With reference now to accompanying drawing, structure of the present invention and operation are described.
As shown in Figure 2, comprise that according to evaporimeter of the present invention a pair of unit of collector pipe up and down 101 that each has an input pipe 151 and an efferent duct 152 and 102, two rows connect the pipe 200 of collector pipe unit and are arranged on folding fin 400 between the pipe.
Herein, box component 110 has been extruded into a U font cross section, so that two ends 111 of width are orientated by same direction.If desired, can obtain as shown in the figure W font cross section by the mid portion of the U font that curves inwardly.
The tube sheet 120 that catchments is assemblied between two sides of box component, thereby is used for sealed inner, and left and right sides is then near the inboard of two sides.The tube sheet 120 that catchments has many pores 121.
Baffle plate 130,131,132 forms according to the shape of the width that is formed by the box component 110 and the tube sheet 120 that catchments, so that the inner space longitudinally is spaced apart, spacer member 140 forms according to the shape of the length direction of the inner space that is formed by the collector pipe unit 100 and the tube sheet 120 that catchments, to enable broad ways inner space at interval.
At this moment, as the characteristic of the box component 110 of the present invention and the tube sheet 120 that catchments, box component 110 has a U font cross section (or W font cross section as shown in the figure) by the extrusion method manufacturing, and the tube sheet 120 that catchments is then according to the process for stamping manufacturing.After, as shown in Figure 7, the end of two widths of the tube sheet 120 that catchments all is inserted in the inboard of both sides of box component 110 regularly, gives soldering then.
The characteristic of the box component 110 that is used to improve assembly performance is described below.
Shown in Fig. 3 to 6, two sides 111 at box component 110 form a groove 111b along its length, then can be with two sides of the tube sheet 120 that catchments regularly in the insertion groove.
Therefore, might in a manner described the tube sheet 120 that catchments temporarily be fixed on the box component 110.In the present invention, omit traditional temporary transient welding by the said fixing measure.
The characteristic of the tube sheet 120 that catchments that is used to improve assembly performance is described below.
As shown in Figure 4, so the tube sheet 120 that catchments of assembling is configured as the shape bending of pressing baffle plate, with binding ability and the performance of ventilating of raising with box component 110.
As shown in Figure 6, its degree of crook is that radius R equals 75～85mm.
Therefore, middle baffle plate all contacts with the inner surface of the tube sheet that catchments with the end stop that will illustrate later on.Herein, middle baffle plate and end stop each have the radius R of 75～85mm.
The value of radius R is determined according to the experiment of Figure 19.That is to say, after evaporimeter installed, the air velocity that produces by fan changed over from 2.5m/s, 2.0m/s to 1.5m/s, and radius R then changes to 105mm from 60mm, consequently know, when radius R is 75～85mm, obtain best performance of ventilating.
Have again, longitudinally in the middle of the tube sheet 120 that catchments, form a sweep 123a, simultaneously, on lateral surface, form the projection 123b of a bending.In above-mentioned structure, the lower end of spacer member 140 be inserted in box component 110 the bottom in the middle of in the vertical groove 112 that forms, then insert among the crooked groove 123a its upper end.
The groove 125 of one level forms in the tube sheet 120 that catchments and crosses at two sides.The upper end that is assemblied in the baffle plate 130 in two sides of box component 110 is inserted in the level trough 125.Therefore, baffle plate 130 can not gone to the outside of box component.
The characteristic of the baffle plate 130 that is used to improve assembly performance is described below.
As shown in Figure 2, baffle plate 130 comprises that more than at least one middle baffle plate 131 and a pair of end stop 132 the former is used for the volume inside of collector pipe unit 100 at interval, and the latter is used for two lateral end seal inner spaces in collector pipe unit 100.
In addition, as shown in Figure 8, baffle plate 130 can have a groove that cuts out 134 in certain part, is assembled together with spacer member 140 being used for.One of baffle plate 132 has a pair of pore 133, to be used to connect a fluid inlet tube 151 and a fluid outlet 152.
When connecting fluid intake pipe 151 and fluid outlet pipe 152, the adapter 300 of Fig. 2 preferentially is set, to be used to improve the convenience and the sealing force of connection with pore 133.
As shown in Figure 9, adapter 300 comprises that insertion tube portion 310 in the pore 133 of a pair of insertion end stop 132, a pair of tube connector part 330 that is used to connect pipe and a pair of insertion tube portion 310 wear the slotted hole 301 to tube connector part 330.
As shown in figure 10, when the insertion tube portion 310 that will manage connection adapter 300 is connected on the end stop 132, form the edge 320 of a circle outside on the diameter parts.Therefore, it is inserted in the pore 133 of end stop 132, is blocked by the edge 320 of circle until it, and its end is then by enlarging and flange regularly.
The characteristic of the spacer member 140 that is used to improve assembly performance is described below.
As shown in figure 11, spacer member 140 can need comprise a groove that cuts out 2 (143) with the mid portion that middle baffle plate 131 is assembled together one.Can form a groove that cuts out 141 in the end, be assembled together with end stop 132 being used for.
Side at mid portion can form a through hole 142, is communicated with space, the left and right sides being used for.Spacer member 140 has improved the intensity of box component 110 and has prevented distortion.
Characteristic according to chest 200 of the present invention is described below.
As shown in figure 14, pipe 200 has the width W of one 30～50mm and the thickness T of one 1.5～3.0mm, and then there are the width TW of one 1～3mm and the thickness T T of 0.5～3.0mm in coupling part 230.
The width TW of coupling part 230 and thickness T T determine according to the experiment of Figure 20 and 21.
With regard to the experiment of the heat radiation degree of Figure 20, when the width TW of coupling part is 1.0～3.0mm, and the height of folding fin 400 is when being respectively 5.5mm, 7.5mm and 9.5mm, and the heat radiation degree does not change, and when the scope of width surpassed 3.0mm, heat produced performance and just reduces.
In addition, with regard to the experiment of the loss of air pressur of Figure 21, when the width TW of coupling part is 1.0～3.0mm,, there are not the pressure loss and variation even change the thickness T T of coupling part yet.When the scope of width surpassed 3.0mm, the pressure loss strengthened.
When thickness T T is 0.0mm (not having the coupling part), as can be seen, compare with the situation that the coupling part is arranged, the bigger pressure loss is arranged in the coupling part.
When current tube portion 210 was connected and blocks with tube portion 220 usefulness coupling parts 230, back, flow air can not flow between the pipe in the next compartment between optional pipe, so that the flow velocity of air improves the cooling performance raising.
Easy speech, because folding fin forms between pipe, therefore, when flow air between optional pipe was subjected to certain resistance by folding fin, air just was directed to along side direction.But, in the present invention, front tube portion divide 210 and the back coupling part 230 is arranged between the tube portion 220, therefore, prevent that air is along lateral flow.
As shown in figure 12, comprise the process portion of making fillet of planar section 240 and on the angle of planar section 240 along the side direction outside according to pipe 200 of the present invention.
When forming planar section 240 on the outer side surface at pipe 200, flow air causes an eddy current in the end in peripheral part of pipe, and this eddy current prevents that condensate water from splashing.
Therefore, in the present invention, might prevent the fin and capillarity pipe between or surface tension gathering of condensate water by folding.Condensate water directly falls in the planar portions office of end and is discharged.
If the angle of two sides of planar section 240 is changeed too soon, then corner may produce eddy current and stop air to flow.Therefore, need a process portion of making fillet 250 with certain circularity.At this moment, the fillet radius of curvature R of making the process portion 250 of fillet is preferably in the scope of 0.5～1.0mm.
0.5 the radius of～1.0mm is relevant with the soldering of the folding fin 400 that forms between each pipe 200.
That is to say that when the folding fin wanted between the soldering pipe, if radius is too big, then the end of Zhe Die fin 400 can not contact with pipe.Therefore, even melt during in soldering when clad material, welding can not be finished to the end.If radius is too little, then in air stream, also strengthened eddy current.
According to the experiment of considering that above-mentioned situation is carried out, the fillet radius of curvature is preferably in the scope of 0.5～1.0mm.
As shown in figure 13, pipe 200 can comprise that one is divided into the inner fin 201 in many spaces with the inner space, and can comprise many dividing plates 202 integratedly, and the latter is divided into the inner space many spaces as shown in figure 14.
In addition, as shown in figure 14, dividing plate 202 is installed by an angle that tilts, so that the flow path of cold-producing medium preferably has a triangle and a side triangle, they repeat in its cross section in order.
As shown in figure 12, folding fin 400 of the present invention has the width 2 (W2) identical with the width W of pipe 200.
That is to say that in traditional technology, when the width 2 (W2) of the width W of pipe and folding fin 400 was identical, folding fin was with regard to pressurized and distortion, so that reduce and ventilate.But, in the present invention, because the end of pipe forms by planar section 240, so folding fin 400 pressurized not, consequently ventilation does not reduce.
