Invention field

The present invention relates to a kind of clothesdriers including heat pump, more particularly to a kind of optimization energy expenditure and/or do The clothesdrier of the duration in dry period.

Background technology

Most of drying machines include the rotating cylinder for being referred to as roller, therefore are referred to as cylindrical drier, the sky of heating Gas circulates through rotating cylinder so that moisture is made to be evaporated from load.Roller, which encloses, to be rotated about the axis thereof.

Known clothesdrier includes two categories：Condensing clothes drying machine and ventilation-type laundry drying machine.First The drying machine of classification makes the air circulation discharged from roller pass through heat exchanger/condenser so as to cooling air and condensed moisture； After heater heating air has been used, drying machine then makes air return to recycling across roller.In operation, The drying machine of second category extracts air, heating air from peripheral region, air is blown into roller, then passes through ventilation hole Air is discharged to outside.

It generally, such as will be from roller since the drying machine of first category is not required for suitably installing special device The exhaust manifolds of damp-heat air discharge, so they are most common in the market.However, generally for equal-wattage and Identical load amount, the arid cycle of condensation dryer in ventilating drier than waiting the periods long.

According to the prior art it has been proposed that several solutions, to improve condensation dryer and ventilating drier Efficiency.Specifically, heat pump techniques have been applied to clothesdrier, to enhance the efficiency of drying clothes.In conventional heat pump In drying machine, air flows in the closed.Roller is passed through by the air that fan moves, removes water from wet clothes, then air It is cooled in evaporator with heat pump and is dehumidified and is heated to be re-inserted into rolling in heat pump condenser Among cylinder.In order to run, heat pump includes air and carries out the refrigerant of heat exchange therewith, and refrigerant is by compressor compresses, It is laminated in the condenser in expansion device and condenses, then evaporated in evaporator.

EP 1209277 discloses a kind of heat pump clothes drier device, wherein accommodating clothes to be dried for driving The motor of roller is also connected on the first fan for recycling dry air and on the second fan of cooling compressor.

US 2011/0280736 is related to a kind of method for controlling drying machine.A kind of control includes having speed changing type compressor Heat pump drying machine method, which includes the following steps：At least one of selection supply air or dry air Route；When implementing selected route, the startup speed of compressor is increased into target velocity；And it adjusts and is arranged in heat pump Expansion valve aperture.

Invention content

The present invention relates to a kind of clothesdrier for being used for drying clothes and other clothes, which includes having The heat pump of first heat exchanger and second heat exchanger.The clothesdrier of the present invention can include ventilating drier or cold Solidifying formula drying machine.The configuration of heat exchanger in the clothesdrier of the present invention is such that the spy according to clothesdrier Determine geometry realize, the best heat transfer ability of substantially custom-made.Preferably, according to the internal part of clothesdrier Layout, the layout of especially preferably air loop and optional fan, there is the cloth drying of the special air loop configuration Machine is according to the present invention for maximizing the geometry optimization of the heat exchanger of heat exchange between refrigerant and processing air It is obtainable.

Heat pump drier includes hothouse (such as roller), has load to be dried (such as clothes) to be placed on hothouse In.The hothouse be handle air loop a part, the processing air loop in the case of condensation dryer specifically It is open circuit for closed loop or in the case of ventilating drier, which includes drawing in both cases Flow guide is so as to the air conduit of dry load.The processing air loop is connected to the drying by its two opposite ends On room.Preferably, hot dehumidified air is fed in hothouse, so as to be flowed on clothing, and generated tide Wet cooling air leaves the hothouse.The moist airflow being rich in vapor is then fed into the evaporator of heat pump, In evaporator, moisten warm processing air be cooled and in the presence of it moisture condensation.Generated cooling is Dehumidified air is then expelled in dryer outer, the environment that the drying machine is located at or the air is relayed in closed loop It is continuous.In this second case, the dehumidified air in treatment loop is then before being again introduced into hothouse by means of heat The condenser of pump heats, and entirely circulate in terminate arid cycle before always repeat.Alternatively, surrounding air via Entry conductor is from the condenser that environment enters heat pump, and surrounding air is added before hothouse is entered by the condenser of heat pump Heat.

The heat pump of the equipment includes refrigerant circuit, and refrigerant can be flowed in the refrigerant circuit and the refrigerant Circuit connects first heat exchanger or condenser, second heat exchanger or evaporator, compressor and dropping equipment via pipeline.System Cryogen is pressurizeed by compressor and circulates through system.In the waste side of compressor, the steam of heat and height pressurization be referred to as it is cold It is cooled in the first heat exchanger of condenser, until it is condensed into the liquid of high pressure, moderate temperature, so as in processing air It is heated before being introduced in hothouse.The refrigerant of condensation then passes through dropping equipment, such as expansion device, example Such as choker, valve or capillary.Low-pressure, liquid refrigerant is handed over subsequently into second heat exchanger (evaporator) in second heat In parallel operation, fluid with leaving the processing air of hothouse due to carrying out heat exchange and absorb heat and evaporate.Then refrigerant returns It returns to compressor and the period repeats.

In some embodiments, in first heat exchanger and/or second heat exchanger, refrigerant may be not subjected to phase Become.

Hereinafter, the position of the flow direction with term " downstream " and/or " upstream " instruction reference fluid inside pipeline It puts.Additionally, in the present context, term " vertical " and " level " refer to that element is opposite in the normal mounting of drying machine or operation In the position of drying machine.In fact, defined in 3-D spaces by the direction X of two horizontal verticals, Y shape into horizontal plane (X ", Y "), and also define the vertical direction Z " perpendicular to horizontal plane.

Applicant already allows for a kind of heat pump drier, and the wherein first heat exchanger of heat pump and/or the second heat is handed over Parallel operation includes the one or more heat exchanger modules being implemented as described below.Each module includes two header boxs, allows refrigerant stream The outlet header box for entering mould entrance header box in the block and refrigerant being allowed to be discharged from module.In addition to addition entry point header box And/or other than outlet header box, it may also include additional header box.Further, module includes stacking in the stacking direction multiple Heat exchange layers (for example, these layers along assigned direction self be arranged).Although often refer to term " in stacking direction Self upper ground stacks ", but this does not imply that self the ground placement along vertical direction of these heat exchange layers.This only anticipates Taste, and along assigned direction (stacking direction), these layers are that self is placed in order, although stacking direction is also likely to be water Square to.

Each heat exchange layers include the more than one channel for refrigerant stream, these channels are located at the layer adjacent to each other It is interior.These channels are in and are in fluid communication with entrance header box and/or outlet header box, allow refrigerant in this way from entrance header box It flow to outlet header box and/or vice versa.Preferably, multiple channel in each heat exchanger layer with it is parallel to each other. Each heat exchange layers limit two opposite ends：These ends be fixed on entrance header box and/or outlet header box on or It is fixed on extra play (for example, layer of above and or below).

In each heat exchange layers, these channels can be with angled or they can have irregular shape Shape.

Preferably, stacking direction is vertical direction, and these heat exchange layers vertically stack self.

These heat exchange layers have the given width for the number of channels for depending on realization layer and with being formed in the layer of channel Channel be longitudinally extended corresponding be longitudinally extended.It width and is longitudinally extended direction and preferably limits plane.This plane can Can perpendicular to the stacking direction of layer or it can with the stacking direction formed angle.Alternatively, heat exchange layers can be relative to It inclines towards each other or can be with self landform archwise.

The channel of adjacent (that is, neighbouring in the stacking direction) layer in the stacking direction is connected by fin.

The distance that entrance header box and outlet header box can be given with mutual distance, so that the one of each heat exchange layers End connect with entrance header box, opposite end with export header box connect, for example, these heat exchange layers be inserted in entrance header box and Between outlet header box.Alternatively, entrance header box and outlet header box can be positioned so that one contacted with another or Neighbouring (for example, one is located on another top), so that these heat exchange layers can be by one end and entrance header box Or outlet header box attachment and its opposite end and additional intermediate header box are attached, be oriented and entrance header box and gone out Mouth header box distance gives set a distance.Also in this case, one end of each heat exchange layers joins with entrance header box or outlet Bobbin carriage connection, the other end are connect with additional header box, so as to which each layer is still inserted in always between two header boxs.First In the case of kind, in order to reach outlet header box from entrance header box, refrigerant passes through single heat exchange layers, and in the second situation Under, refrigerant must flow through at least two heat exchange layers from entrance header box, and refrigerant stream is in one layer during this is two layers Tool has essentially the inverse direction there are one direction in another layer, to reach outlet header box.

In the different additional embodiments of heat exchanger module, entrance header box and outlet header box respectively with it is multiple Individual layer connection in layer.For example, entrance header box can be along highest (or minimum) layer in stacking direction and multiple layer Free end connection, outlet header box can be connect with the free end of minimum (or highest) layer.Other each layers in multiple layer (except top and lowermost layer) is then connected by its corresponding adjacent layer in its end (above or below), this results in The bending that the end of one layer one end layer adjacent thereto is connected.By this method, single group channel forms all layers, and this group Channel repeatedly folds, so as to form zigzag pattern.

In all embodiments, multiple channel is at least partly through being subject to processing air stream, so that is flowed in channel There are heat exchanges between dynamic refrigerant and processing air.Therefore, purpose thus at least partly, the entire extension for them For preferably, the channel of the heat exchange layers of the module of first heat exchanger and/or second heat exchanger is preferably located in sky In airway, which is the part for handling air loop.

Header box has the function of to keep different layers and/or be used as entering mould import in the block for refrigerant and/or going out Mouthful.

Applicant have appreciated that the processing air flowed in the air loop of known clothesdrier is spatially simultaneously It is not uniform, in other words, it is in air conduit and without unified space flow speed.Air conduit is taken in its any position On cross section, flow through the air in the section has generally different speed, and this in the difference in the section Outside, flow velocity is different in the different zones in the section.

In addition, the flow direction of air is equally not always parallel to the wall of air pipeline.The streamline for handling air stream can To follow the complex pattern in air pipeline, including whirlpool and turbulent flow.

This inhomogeneities is caused by air pipeline construction in itself：Processing air inside clothesdrier leads to It is often flowed not along straight catheter, on the contrary, there is processing air in pipeline and the such as element of the end of a thread filter Several bend pipes that stream must traverse and that turbulent flow and flow deviation may be caused and bending part.

For example, in some drying machines, processing air is left dry by the hole realized in the boundary of the door of shell Dry room, and handle air and be bent downwardly to pass through the filter for collecting the end of a thread.Further, processing air is curved again Song to be flowed in the base portion of shell, be usually available in the base portion for position heat pump heat exchanger space.

In other drying machines, processing air by hothouse in itself in, realize in the uppermost region in hothouse Hole leave the room, and return in the room via the hole realized in the lowermost region of the room, processing air thus in clothing It is flowed in the top area of the shell of object drying machine, heat exchanger is positioned in top area so as to hot with processing air exchange Amount.

In addition, generally, fan is present in air pipeline to blow processing air, so as to force processing air along Air loop recycles in itself.Similarly, by several elements inside the volume and the volume that are limited by shell there are institutes The constraint forced, fan is simultaneously not always centrally located relative to air pipeline, but it may be eccentric, this implies it By air be blown into one (or multiple) in the side wall of pipeline than another (other) closer to.Therefore, fan is this Bias also causes asymmetry on the flow velocity across the processing air of air pipeline.

Since heat exchange mainly occurs, and the wing of the heat exchange layers stacked in connection in the channel for forming heat exchange layers Occur in piece, so applicant have appreciated that, flow through the processing air of module and its spatial non-uniformity of turbulent flow Influence the heat exchanger effectiveness of module.

Heat exchanger another common problem encountered is that, heat exchanger, which is generally designed to maximize, must exchange heat Two kinds of fluids (be in this case refrigerant and processing air) between surface area, while minimize to passing through exchanger Fluid stream resistance.Therefore, it is however generally that, these heat exchanger modules are designed to have most wide possibility heat exchange table Face.However, in the utensils such as such as drying machine, it is limited for the space of any part, and therefore must be with as small as possible total Volume realizes the maximization of heat exchange surface.The gross area of heat exchange surface is limited by the volume available of this or these module System.

Applicant have appreciated that can be with the geometry of optimization module, without changing the overall structure of module, this is dark Show that the cost for building module and manufacture complexity holding are basically unchanged.In other words, applicant have appreciated that, mould can be increased The available surface of heat exchange in the block, the overall volume that occupies for keeping module is identical, and at the same time optimum geometry realization pair Across the better control of the air-flow of heat exchanger module.

In order to maximize heat exchange surface, applicant has optimized the geometry of fin, wherein to be located The maximum extension for the heat exchange surface that reason air flows at most.It has been discovered by the applicants that by the first and second adjacent heat exchanges Device module is connect with shared fin, that is, the first module layer and the second module layer share identical multiple fins, while both increase Add the available surface of heat exchange and reduce the turbulent flow across the air-flow of module.The latter's effect is due to passing through fin in itself Processing air " tunnel-effect " caused by, these fins are relatively long (bridge joint two modules) in the direction of the air flow.

In this context, fin is to include extending will pass through from object (in this case, being heat exchange layers) Increase convection current to increase the element on the surface of heat transfer rate.

Fin is added to the table increased on object (being the surface of heat exchange layers in this case) for heat exchange Area.The fin of any types and geometry can be applied to the present invention.Preferably, fin is inserted in two neighbours of module Between the heat exchange layers of nearly vertical stacking.Fin can reside between each pair of adjacent heat exchange layers or exist only in them Some between.

Fin includes the wall for foring heat exchange surface.

According in a first aspect, the present invention relates to a kind of clothesdrier, which includes：

A. shell, shell support have the hothouse of load to be dried for reception；

B. air pipeline is handled, which connects with the hothouse, and in the processing air pipeline, processing is empty Air-flow is readily flowed；

C. heat pump, the heat pump have the heat pump circuit that refrigerant can flow wherein, and the heat pump circuit includes：First Heat exchanger, the refrigerant is cooled in the first heat exchanger and the processing air stream is heated；And second heat hand over Parallel operation, the refrigerant is heated in the second heat exchanger and the processing air is cooled；The first heat exchanger and/ Or the second heat exchanger is thermally coupled on the processing air pipeline, described in performing and being flowed in the heat pump circuit Heat exchange between refrigerant and the processing air stream；The first heat exchanger and/or the second heat exchanger are into one Step includes first heat exchanger module and second heat exchanger module, and each module includes

The refrigerant stream is directed in the heat exchanger module by ■ entrance header boxs, the entrance header box；

■ exports header box, which discharges the refrigerant from the heat exchanger module；And

The entrance is fluidly connected to the outlet header box by the more a heat exchange layers of ■, multiple heat exchange layers, so as to The refrigerant is enable to flow to the outlet header box and/or vice versa from the entrance header box；The layer is pre- Self ground stacks on fixed stacking direction, and each layer includes multiple channels；

It is characterized in that, the first heat exchanger module and the second heat exchanger module are to be mounted adjacent one another , and the first heat exchange layers of the first module with the second heat exchange layers of second module consistent with the stacking direction It being separated by gaps on direction, the first heat exchanger module and the second heat exchanger module include multiple fins, this A little fins are arranged in both first heat exchange layers and second heat exchange layers and extend through the gap.

According to the present invention, belong to same heat exchanger (for example, the two, which belongs to first heat exchanger or both, belongs to Two heat exchangers) or belong to different heat exchangers (for example, the first module may belong to first heat exchanger, and the second module category In second heat exchanger) the first heat exchange module and the second heat exchange module be located adjacent to.In the first module First layer and the second module the second layer between there are gaps.

Typically, since the layer of a module cannot be contacted with the layer of adjacent block, so there are gaps.This is because for example The size of header box is usually more wider than the width of these layers or since other limitations cause.Therefore, although the first module this Those layer of adjacent positioned (even minimum) of a little layers and the second module, there are spacing or gaps between two groups of layers.

The size in gap is defined with the following methods.First layer and the second layer respectively include the first boundary edge of face each other Edge and the second boundary edge.The distance between first edge and second edge are the size or length in gap.Gap size need not It is uniform：First heat exchanger module can be parallel with second heat exchanger module, for example, with parallel to each other Layer, so that the gap between first layer and the second layer is base along the first layer of face each other and the external margin of the second layer It is constant or be angled with respect to each other in sheet, so that the distance between first edge and second edge are along edge Extension and lasting variation.

In other words, the size in gap is two heat exchange modules along the separated spacing in a direction.The gap defines One direction means, which extends along line not parallel with stacking direction, i.e., it forms connection first layer and the Two layers of line, on the contrary it is consistent with stacking direction.This and then it is meant that first heat exchanger module and second heat exchanger module Along stacking direction, self ground does not position.

According to the present invention, first heat exchanger module is connect by multiple fins with second heat exchanger module, these fins It is arranged on the first heat exchanger layer of the first module and on the second heat exchanger layer of the second module.Multiple fins are also worn The gap between first layer and the second layer is crossed, forms the bridge joint from the first module to the second module.

For example, in embodiment, a fin in multiple fin includes wall, and this wall is located at the upper of first layer On the top on surface and on the top of the upper surface of the second layer, and it also extends through the gap as discrete component.

Using this geometric configuration, there are two module (each moulds for overall volume and tool that heat exchanger of the invention occupies Block has fin between each layer of module itself, does not extend to adjacent block) heat exchanger it is identical, but exist simultaneously Wider heat exchange surface.Surface after increase includes extending through the finless parts in the gap between module.Meanwhile fin Wall forms in " tunnel ", and guiding processing air passes through module, and turbulent flow is minimized.In fact, length " the tunnel formed with fin Road " (these tunnels not by the end of module interrupt) is so that the air distribution in air pipeline where module is more uniform.

The presence of shared fin in two modules in addition improve individual unit mechanical resistance (this be by fin that This fixed two module itself can encounter).The installation of this unit in the air pipeline of drying machine is simplified, because single A unit (rather than two units) must be positioned and is aligned.

It should be understood that more than two module can be attached by identical multiple fins.If for example, the first heat Exchanger module, second heat exchanger module and third heat exchanger module are all mounted adjacent one another, individually multiple Fin can be located on one layer of each module, and in this case can extend across two gaps, and a gap is present in Between first module and the second module, and second gap is present between the second module and third module.

This structure is suitable for the adjacent block of any quantity N.

In above-mentioned aspect, alternatively or in combination, there may be characteristic additionally below.

According to preferred embodiment, first module includes third heat exchange layers, the third heat exchange layers and described first Heat exchange layers form first pair of adjacent heat exchange layers on the stacking direction together, and second module includes the Four heat exchange layers, the 4th heat exchange layers form second pair of heat in the stacking direction together with second heat exchange layers and hand over Change layer, the multiple fin is arranged in described first pair between the first layer and third layer of the second centering and second respectively Between layer and the 4th layer.

Therefore, each module is included at least along the adjacent heat exchanger layer of a pair of stacking direction.In the first module It is more that this is inserted between layer between layer in first pair of this kind of adjacent layer and in this kind of adjacent layer of the second couple of the second module A fin.In the present invention, be not that there are between these layers in first pair multiple fins, but the layer in second pair it Between there are multiple fins for separating, including individual multiple fins and these fins from the first module " extension " arrival second Module, in other words, identical multiple fins are adjacent by second pair in the block with the second mould of first pair of adjacent layer in the first module Layer connection.

In an advantageous embodiment, the distance between adjacent heat exchange layers of first and third of the first centering and described second Centering second and the 4th the distance between adjacent heat exchange layers be substantially identical.

By this method, the size of multiple fin keeps uniform, for example, in fin from a module to another module In extension, multiple fin for example not only keeps identical spacing, also keeps identical height, without particularly changing.Therefore, Standard fin can be used.

It is highly preferred that the multiple fin defines height on the stacking direction, the height is substantially equal to institute State existing distance or hot equal to second between first pair or the first heat exchange layers of second centering and third heat exchange layers Existing distance between switching layer and the 4th heat exchange layers.

Therefore these fins occupy this all free space between adjacent layer of each module, the heat for limiting it Exchange surface maximizes.

Advantageously, the gap is present on the direction substantially perpendicular to the stacking direction.

It is front and rear each other on the flow direction of the processing air of first module and the second module preferably in air conduit to put It puts, and places with being preferably parallel to one another, so that be easier to install, and by shared volume minimization.It is highly preferred that Gap direction is substantially parallel direction.

In a preferred embodiment, the length in the gap is preferably incorporated between 5mm to 50mm.

Preferably, first heat exchange layers and the second heat exchange layers are respectively provided with the first width and the second width, described The width of multiple fins is substantially equal to the summation of the length of first width, second width and the gap.

Further more, in order to make to be maximized by the heat exchange surface that multiple fin limits, the width of these fins is as far as possible It is wide, thus cover the entire width of first layer, the entire width of the second layer and the length in gap therebetween.

In most popular embodiment, the first heat exchanger module and the second heat exchanger module are located at institute In the air conduit for stating air pipeline, the multiple fin includes multiple walls, and each wall is defined from described first and/or described The heat exchange walls surface that second heat exchange layers extend out, the multiple wall are arranged so that is flowed in the air hose The flow direction of the processing air is arranged essentially parallel to the heat exchange walls surface.

Multiple fins define the multiple tunnels formed by fin walls by this method, these tunnels are used as in air pipeline Handle the guiding tool of air.Therefore, the turbulent flow for handling air is minimized in this way.

Preferably, the first heat exchanger module and the second heat exchanger module are located at the sky of the air pipeline In airway, first module and second module and the air conduit are reciprocally arranged so that in the sky The flow direction of the processing air flowed in airway is substantially perpendicular to the stacking direction.

The heat exchange layers that heat exchange wherein occurs are located among a part for air loop.It is excellent in order to maximize heat exchange Choosing is to flow through the processing air stream of air conduit " to hit " module substantially in vertical manner, that is, its mode is makes It is basic to obtain by module stack direction and the direction of processing air stream being longitudinally extended in the module flat and air conduit limited It is upper vertical.By this method, air turbulence is minimized and heat is transmitted and is maximized.Therefore, in first heat exchanger and In the case that both two heat exchangers include module, preferred configuration is that have two moulds substantially parallel in air conduit Block.It is highly preferred that the two modules also are normal to being longitudinally extended for air conduit.

Advantageously, the first heat exchanger module and the second heat exchanger module are located at the air pipeline In air conduit, the air conduit and first thermal modules and second module are reciprocally arranged so that entrance The flow direction of the processing air in the air conduit is arranged essentially parallel to the heat exchange layers.

In this embodiment, since different heat exchange layers are parallel to processing air-flow direction in itself, so by flowing The resistance encountered across the processing air of module is minimized.

The tunnel-effect of fin is best simultaneously.

Advantageously, the first heat exchanger module and the second heat exchanger module are located at the air pipeline In air conduit, the air conduit and first module and second module are reciprocally arranged so that into institute The flow direction for stating the processing air in air hose is arranged essentially parallel to the direction in the gap.

These modules thus preferably front and rear positioning each other on the flow direction of processing air, to make heat exchange maximum Change.

Advantageously, which includes the fan for the processing air to be made to be recycled in the air pipeline.

In general, the fan is constructed such that blow the processing air, mode is so that processing air passes through institute The spatial distribution for stating the flow velocity in the cross section of air pipeline is spatially asymmetric, so as to the higher region of flow velocity and The relatively low region of flow velocity.This is often as fan relative to caused by " non-central " position of air pipeline.Therefore, it is multiple The geometry of fin improves this heterogeneity.

Preferably, first mould is defined in the first heat exchanger module and the second heat exchanger module The second longitudinal direction direction of the heat exchange layers of the first longitudinal direction direction of the heat exchange layers of block and second module, and described first Longitudinal direction and second longitudinal direction direction are substantially parallel to one another.

It is highly preferred that the first heat exchanger module and/or the second heat exchanger module are arranged so that institute The first longitudinal direction direction and/or the second longitudinal direction direction for stating heat exchange layers are substantially perpendicular in the air conduit The flow direction of the processing air.

The geometric position of these modules is to optimize always, to maximize heat exchange and to make in air conduit Air turbulence minimizes.

In a preferred embodiment, the entrance of first heat exchange module and/or second heat exchange module joins Bobbin carriage and the outlet header box position on self ground along the stacking direction.

In particular configuration, one or both of the first module and the second module have the entrance connection self stacked Bobbin carriage and outlet header box.For example, it can realize these header boxs by being divided into two sections of same pipe by separator.Each For another section of Duan Buyu in direct fluid communication, refrigerant has to flow through this or these layer to be reached out from entrance header box Mouth header box.

According to advantageous embodiment, the entrance header box and/or the outlet header box and/or the intermediate header box Section is elongated, and wherein its minimum diameter is less than the width of the layer.

Preferably, the header box of the module of these heat exchangers is elongated, for example, there is oval or rectangle to cut for they Face, to be further reduced the internal volume of these exchangers so as to reduce space and also to save some refrigerants.System Cryogen is strictly relatively expensive, and is preferable to minimize that the refrigerant for giving heat exchange amount.Further, since processing air The part that conduit is used to place header box is reduced therefore the extension of channel can be increased, so exchange surface (example Such as, the total surface of channel layer and fin) it can be increased.In one direction, the minimum dimension of cross section is fixed：It Must it is wide enough to be connected on one end of layer and therefore it must at least as layer it is wide.However, in vertical direction, Maximum width or diameter can be decreased below the width of layer.

It is highly preferred that the entrance header box and/or the horizontal stroke of the outlet header box and/or the intermediate header box Section is ellipse or rectangle.

Advantageously, the channel has the hydraulic diameter less than or equal to 5mm.

According to an embodiment of the invention, in hydraulic diameter D_HIt is defined as

Wherein, in the case of the profit week of cross section that A is the cross-sectional area of channel and P is channel, the water of each channel Power diameter is less than or equal to 5mm, i.e. D_H≤ 5mm, more preferably D_H≤ 3mm, even more preferably D_H≤1mm。

Due to the size of hydraulic diameter, module of the invention can include many channels, therefore refrigerant stream is divided into Multiple smaller refrigerant streams, each one stream of channel.By this method, in the pressure drop and larger passage of the refrigerant in channel Refrigerant pressure drop is compared and is decreased.

Additionally, it is known that the maximum pressure that pipe can be resistant to is inversely proportional with its hydraulic diameter.Therefore small hydraulic diameter The pressure that meaning channel can be resistant to is higher than larger pipe.For this reason, in the heat pump circuit of the drying machine of the present invention In can use high-pressure refrigerant, such as carbon dioxide.

In addition, it is still due to smaller size, compared in standard heat pump drying machine, needed for the appropriate operation of module The amount smaller for the refrigerant wanted.Since required amount is low, it is also contemplated that using inflammable hydro carbons.

The cross-sectional shape of channel is incoherent for the present invention, and it can be rectangular, rectangle, circular (in this case, hydraulic diameter is consistent with diameter of a circle), ellipse, etc..For all logical in multiple channel Road, the cross section of multiple channel need not be identical, but it can be different, and different channels can have with above-listed The combination of possibility cross section gone out.In addition, cross section can change along extending in hydraulic diameter and/or shape the two for channel Become.

Preferably, the heat exchange layers include multiple channels parallel to each other.

Preferably, these channels extend, and along the direction for being arranged essentially parallel to horizontal plane when drying machine is run Perpendicular to the flowing of processing air stream.In other words, it is therefore preferred to have much smaller than its length diameter channel from the first header box Extend to the second header box, mode be so that they be longitudinally extended result be arranged essentially parallel to horizontal plane and perpendicular to Handle the flowing of air (heat exchange occurs with the processing air).

If these channels are straight lines, they are longitudinally extended the longitudinal axis of (and longitudinal direction) corresponding to them. If these channels are not straight line, such as their formation arch, they are longitudinally extended (and longitudinal direction) corresponding to engagement One point (these channels leave from the point from entrance header box/outlet header box) and first point of (this first point and entrance connection Bobbin carriage/outlet header box longitudinal axis have maximum distance) line.

According to the first embodiment of the module 10 of the drying machine 1 of the present invention described in figs 4 a and 4b, entrance header box 5 With outlet header box 6 by vertically (i.e. their axis Z is the vertical axis Z " of drying machine 1) mounted on the base portion of drying machine 1 It is parallel to each other on 24, and X is substantially straight to the channel 7 of two header boxs 5,6 of connection along the longitudinal direction.Stacking direction Z It is parallel to vertical direction Z ".Channel 7 is divided in heat exchange layers 8, wherein every layer includes limiting upper surface 9a and lower surface 9b The different pipes of (see Figure 10), channel 7 are implemented in the pipe.Entrance header box 5 is connected to outlet union by multiple heat exchange layers 8 On case 6, all heat exchange layers have to be connected to opposite first end 8b and the second end 8c, the first end longitudinally of one another On the entrance header box and the second end is connected on the external connection bobbin carriage.Heat exchange layers along vertical direction Z self It stacks.In addition, each heat exchange layers 8 have the width direction Y for being longitudinally extended X perpendicular to these channels 7.In the present embodiment In, this width direction Y is parallel to horizontal plane (X ", Y ") and air-flow direction；That is, these layer planes (X, Y) are horizontal (being parallel to horizontal plane (X ", Y ")).In other words, module 10 is mounted so that these heat exchange layers 8 form processing air The parallel horizontal plane flowed therebetween.In each header box 5,6, each heat exchange layers end 8b, 8c it is corresponding Place, multiple hole 7a are implemented, and a channel 7 is inserted into each hole 7a.The row (only visible in figure 3) of the hole 7a formed in this way It is parallel to each other and be longitudinally extended Z perpendicular to header box 5,6.

Refrigerant R is via ingate 5_EnterEnter the connection of module 10 along the flow direction for being longitudinally extended Z for being parallel to header box 5 Bobbin carriage 5, and branch into each channel 7 via hole 7a.Heat exchange layers 8 be according to the flow direction of refrigerant each other " parallel " , it means that refrigerant flows in the same direction in all layers.In each channel 7 for forming identical layer 8, refrigeration The flowing of agent is arranged essentially parallel to flow direction of the refrigerant in other channels and with the same direction.Refrigerant passes through after By the outlet opening 6 of outlet header box 6_{Go out}Leave module 10.

Flow directions of the refrigerant R in header box 5,6 is substantially perpendicular to processing air stream.In addition, refrigerant is entering Flowing in mouth header box 5 is parallel to flowing of the refrigerant in header box 6 is exported, but with opposite direction.

In the different embodiments do not described, the refrigerant flowing in entrance header box and outlet header box can also be flat It is capable and with identical direction.

According to another embodiment of the module 10 of the discribed present invention in figs. 5 a and 5b, entrance header box and go out Mouth header box 5,6 self ground on stacking direction Z stacks.In other words, entrance header box and outlet header box 5,6 are by phase What same pipe or pipe were formed, the transverse separators 17 including the pipe to be divided into two sseparated parts.This embodiment Module 10 thus including three parallel vertical header boxs being connected by heat exchange layers 8, but two in these header boxs Header box (entrance header box and outlet header box 5,6) is implemented as the single pipe being divided into two.Third header box 5a is to use In the intermediate header box of refrigerant stream.Heat exchange layers 8 are parallel to each other, define the layer plane for being parallel to horizontal plane (X ", Y ") (X, Y).Each layer 8 includes two opposing longitudinal ends 8b, 8c, and one end is connect with entrance header box or outlet header box 5,6, And the other end is connect with centre header box 5a.Into entrance header box 5 refrigerant stream therefore by separator 17 prevent so as to from Entrance header box reaches outlet header box.Therefore these heat exchange layers 8 are divided into two groups：First group of G1 (enters first part 5 Mouth header box 5) it is connected on intermediate header box 5a, and intermediate header box 5a is connected to second part (outlet by second group of G2 Header box 6) on.

It is flowed through on vertical direction Z into the refrigerant R of entrance header box 5 and first group of G1 heat exchange layers is distributed to by hole 7a In 8, and the refrigerant flows in the parallel channels in first group of G1 towards intermediate header box 5a.Therefore, in first group of G1 These layers relative to refrigerant levelling row.Refrigerant stream leaves first group of G1 heat exchange layers 8 and enters intermediate header box 5a, In intermediate header box, they merge.From intermediate header box 5a, refrigerant stream subsequently into second group of G2 heat exchange layers 8, so as to Reach outlet header box 6.Therefore, these heat exchange layers in second group of G2 are parallel to each other also relative to refrigerant stream.However, two These layers in a group of G1, G2 are series connection relative to refrigerant stream.In fact, refrigerant is handed in all heat for belonging to same group It changes in layer and parallelly flows, but it must be passed through with given sequential flowing in first group and second group of heat exchange layers-the two groups These layers therefore be series connection.

According to the additional embodiment of the module 10 for the drying machine according to the present invention 1 described in Fig. 6 a and Fig. 6 b, module 10 Only include two header boxs 5,6, entrance header box and outlet header box.In this case, header box is located at horizontal plane On (X ", Y "), placed more preferably along air-flow direction Y ".In addition, not every layer all with entrance header box and The connection of both header boxs 5,6 is exported, on the contrary, only top and lowermost layer is connect respectively with entry level and outlet layer.Other End 8b, 8c of all layers 8 are connected to its adjacent layer, for example, one end is connected to its lower end and one end is connected thereto layer.Cause This, different layer 8 is substantially to be formed by single tube channel, and pipe itself bending of the single channel is repeatedly to form heap Lamination.It is that the entrance header box being placed in substrate 24 is arranged essentially parallel to processing air flowing side with outlet header box 5,6 To Y ", the refrigerant flowing also generated in header box is parallel to horizontal plane (X ", Y ").However, entrance header box and going out Mouthful header box 5,6 is located at different height in Z " base portions 24 along vertical direction, thus be all formed by single pipe it is multiple Self ground on stacking direction Z still corresponding with vertical direction Z " of layer 8 stacks.Channel layer 8 is parallel to each other, and It is longitudinally extended X perpendicular to processing air-flow direction Y ".It realizes that the single pipe of different channels 7 has in it and limits first The first straight line part 8e of channel layer, the first passage layer are connect via an end 8b in its end with entrance header box 5, Then the pipe includes return bend 8f and it is parallel to first part 8e and extends towards second straight line part 8g, the second straight line Part defines second channel layer, etc., and the last straight line portion 8z until forming last layer, the last straight line portion passes through Its end 8c is connected to outlet header box 6.By this method, single trepanning 7a is formed in each header box 5,6, and is believed that Refrigerant stream in different layers 8 is series connection relative to refrigerant stream.Form the refrigerant in the different channels 7 of channel layer Stream is parallel to each other.In addition, planar channel layer (X, Y) is parallel to horizontal plane (X ", Y ").

The stream of entrance header box and the refrigerant R in outlet header box 5,6 are preferably parallel to each other.The two streams can With identical direction or opposite direction.

It is highly preferred that in each module 10,10 ', multiple fin 50 is in stacking direction Z, Z ' on two adjacent layers Contact.Preferably, in each module 10,10 ', have at least a pair of adjacent heat exchange layers 8 to, 8 pairs ' (see Figure 12), quilt It is defined in same module 10,10 ' along stacking direction Z, Z ' most similar two layers.Two adjacent layers in every pair it Between be inserted into more fins 50, and the opposing surface of more preferably its two each layer with every centering is in contact.

Multiple fins 50 are more than on the first layer and the second layer that are individually positioned in the first module and the second module, Er Qieqi The space between first layer and the second layer is also taken up, that is, it extends through gap g.Therefore, make the big of two modules 10,10 ' It is small to remain unchanged, for example, identical with situation discribed in Fig. 8 a, Fig. 8 b, the module 10,10 ' of Fig. 9 a-9c of the invention Heat exchange surface be increased.

As can be seen in Figure 11 and Figure 12, the length of multiple fins 50 is equal to the gap, first layer and the second layer In other words the summation of length, is equal to the length of W+W '+g.

The height h of multiple fin is preferably equivalent to first pair and/or second pair 8 pairs, 8 pairs ' in two adjacent layers it Between existing space D 1, D2.It is highly preferred that between these layers of 1 and second centering of space D between these layers of the first centering Space D 2 be substantially identical, and then equal to multiple fins 50 height h.

By this method, the fin 50 of most of available width and height for occupying module 10,10 ' is used in heat exchange Surface maximizes.Such as in Figure 12 a (enlarged view for showing Figure 12 of first pair and second pair 8 pairs, 8 pairs ' heat exchange layers) It is visible, these fins 50 respectively include from first layer and the second layer 8,8 ' extension (and be preferably also from first layer and The second layer forms a pair of equivalent layer extension) wall 50w.Each wall 50w defines a heat exchange surface 50s, the heat exchange Surface is the surface (certainly, there are the other surfaces that heat exchange occurs in the module) that heat exchange occurs.

In view of the total volume of the free space and module between two adjacent layers of disparate modules preferably remains unchanged, Surface 50s using the geometry of above-mentioned fin may be it is basic under it is most wide, it is too many without increasing in the manufacture of module Complexity, for example, need not consider extremely complex surface.

In addition, as in Fig. 9 a, Fig. 9 b it is better seen that, the wall 50w of fin defines the " tunnel for handling air Road " t.These tunnels t is substantially along processing air-flow direction Y " extensions.By this method, the wall 50w of fin 50 will handle sky Gas is directed across module 10,10 ', so as to reduce possible vortex and turbulent flow.It is identical with the example of Fig. 8 a and Fig. 8 b, it is relatively short Width after the interruption in tunnel will not obtain this kind of efficient result.By fin wall 50w realize these tunnels t therefore It improves refrigerant R and handles the heat exchange between air, so as to reduce the turbulent flow of processing air.

Although in Fig. 9 a-9c, Figure 11 and the discribed embodiments of Figure 12, each pair of adjacent layer in module 10,10 ' includes Multiple fins, it will be appreciated that, it is somebody's turn to do or these centerings only has some layers to may include being located between form that a pair two layers Fin.It can be non-finned to layer that mould is in the block a certain or certain.In addition, not all multiple fins can extend across two Module, in some cases, these fins can be restricted to the single pair adjacent layer of individual module.

In attached drawing 3, Fig. 4 a-4b, Fig. 5 a-5b, Fig. 6 a-6b, Fig. 7 a-7b, Fig. 9 a-9c, although same mould is in the block each The spacing of the distance between layer and multiple fins seems constant, but this is intended merely to the clear of attached drawing and simplifies, in office In the embodiment what is referred to, module 10,10 ' can be realized as in the variable spacing with multiple fins and/or same module Adjacent heat exchange layers between variable range.

In the case where the more than two module 10,10 ' of connection according to the present invention is present in air pipeline 11, such as example As depicted in Figure 2, the processing air successive strokes disparate modules flowed in air pipeline 11.Therefore, because module sheet Body and specifically caused by fin is to processing air stream " turbulent flow minimum effect ", first is impacted module down-stream Processing air spatial distribution be different from same module upstream processing air distribution.For this reason, a module The geometry of another module in downstream can be different from the first geometry for being impacted module.This reasoning is suitable for clothing Module present in object drying machine 1.
