Below, with reference to accompanying drawing, embodiments of the present invention are described.The invention is not restricted to following embodiment.
(the 1st embodiment)
As shown in Figure 1, the heat exchanger 1 of the 1st embodiment of the present invention possesses multiple flat heat-exchange tube 2, inlet header 10A and outlet header 10B.Multiple heat-exchange tube 2 has the shape of rectangle respectively under overlooking.1st fluid (such as, cold-producing medium) is in the internal flow of multiple heat-exchange tube 2.Multiple heat-exchange tube 2 is arranged in outside and forms the stream carrying out the 2nd fluid (such as, air) of heat exchange with the 1st fluid.Specifically, the stream of the 2nd fluid is formed between adjacent heat-exchange tube 2.Inlet header 10A and outlet header 10B is assemblied in the heat-exchange tube 2 of the end face of the heat exchanger 1 in the orientation forming heat-exchange tube 2.
As shown in Fig. 2 A ~ Fig. 2 C, heat-exchange tube 2 has the internal flow path 3 for the 1st fluid flowing.Inlet header 10A is the pipe supplying the 1st fluid for the entrance 3a of internally stream 3.Outlet header 10B is the pipe for discharging the 1st fluid from the outlet 3b of internal flow path 3.Inlet header 10A can be connected with external equipment (not shown) respectively with outlet header 10B.
As shown in arrow A in Fig. 1, the 1st fluid is supplied to the internal flow path 3 of heat-exchange tube 2 from inlet header 10A.As indicated by arrow b of figure, equipment is discharged to the outside with the 1st fluid that the 2nd fluid has carried out heat exchange from outlet header 10B by internal flow path 3.As indicated by arrow c of figure 1, the 2nd fluid, on the direction parallel with the width of heat-exchange tube 2, is being formed at flowing in the space between adjacent heat-exchange tube 2 (multiple outside stream 8).The width of heat-exchange tube 2 is directions vertical with the both sides of the length direction of heat-exchange tube 2 with the orientation of multiple heat-exchange tube 2.
In FIG, the length direction of the width of heat-exchange tube 2, the orientation of multiple heat-exchange tube 2 and heat-exchange tube 2 corresponds respectively to X-direction, Y-direction and Z-direction.In this manual, the orientation (stacked direction) of heat-exchange tube 2 is parallel with the thickness direction of heat-exchange tube 2.2nd fluid flows abreast with the width (X-direction) of heat-exchange tube 2 substantially.
Heat-exchange tube 2 is made up of 1 group of sheet material 11,12 of fitting each other.At least one party selected from 1 group of sheet material 11,12 has the recess forming internal flow path 3.Specifically, heat-exchange tube 2 is made up of the 1st sheet material 11 and the 2nd sheet material 12.1st sheet material 11 and the 2nd sheet material 12 have the recess forming internal flow path 3 respectively.Internal flow path 3 is formed by the 1st sheet material 11 and the 2nd sheet material laminating 12 laminating.According to such structure, the thin-walled property of heat-exchange tube 2 can be realized, be conducive to the miniaturization of heat exchanger 1.In addition, owing to forming heat-exchange tube 2 by the laminating of the 1st sheet material 11 and the 2nd sheet material 12, so use fixture than being easier to and/or carrying out soldering.
Sheet material 11,12 is made up of metals such as aluminium, aluminium alloy, stainless steels.By carrying out punch process to metallic plate to give the shape expected, thus obtain sheet material 11,12.Sheet material 11,12 is such as fitted by soldering.As the raw material of sheet material 11,12, the covering material with core and at least 1 solder layer can be used.
Except collector 10A, 10B, the heat exchanger 1 of present embodiment is only made up of multiple heat-exchange tube 2.Heat-exchange tube 2 is the simple parts be made up of 1 group of sheet material 11,12.Punch process for obtaining sheet material 11,12 is also easy.Compared with finned tube heat exchanger, heat exchanger 1 has easy manufacture, the advantages such as dew are not easily detained in surface.
As shown in Fig. 2 A ~ Fig. 2 C, multiple heat-exchange tube 2 is engaged with each other with outlet 3b place at the entrance 3a of internal flow path 3.One side of 1 group of adjacent heat-exchange tube 2 relative to the opposing party at direction (X-direction) upper offset vertical with the orientation of multiple heat-exchange tube 2.Specifically, multiple heat-exchange tube 2 offsets with respect to each in the direction of the width.Thus, stair-stepping structure is formed from the end side the orientation (Y-direction) of multiple heat-exchange tube 2 towards another side.
As shown in Figure 2 C, the inlet face 14 of heat exchanger 1 tilts relative to the orientation (Y-direction) of heat-exchange tube 2.Inlet face 14 is the faces of the leading edge 2f comprising multiple heat-exchange tube 2.When overlooking heat exchanger 1 from the direction (Z-direction) parallel with the length direction of heat-exchange tube 2, the profile of heat exchanger 1 is parallelogram.According to the heat exchanger 1 with such structure, can obtain in the following benefit be described.The leading edge 2f of heat-exchange tube 2 refers to the edge being arranged in the upstream side of the flow direction of the 2nd fluid of outside stream 8 of heat-exchange tube 2.
As shown in Figure 3A, heat exchange unit 104 in the past possesses multiple heat exchanger 101 (with reference to Figure 13) and pressure fan 16.Multiple heat exchanger 101 is configured in pressure fan 16 around.But the major part of the 2nd fluid is supplied to the inlet face 102 of heat exchanger 101 from incline direction.2nd fluid flow into the outside stream of heat exchanger 101 while significantly changing flow direction.In this case, easily cause the stripping of the 2nd fluid stream, and easily produce the large pressure loss.As a result, heat exchanger 101 cannot give full play to its performance.Consider the space being supplied to heat exchange unit 104, the ability etc. required heat exchange unit 104, the position, size, posture etc. of changing heat exchanger 101 are very difficult.
As shown in Figure 3 B, the heat exchange unit 200 of present embodiment possesses multiple heat exchanger 1 and pressure fan 16.Pressure fan 16 is such as centrifugal blower.Pressure fan 16 possesses rotating shaft and is fixed on the impeller of rotating shaft, sends the 2nd fluid by the rotation of impeller towards the circumferencial direction of rotating shaft.In other words, when the rotation of the end on observation impeller from rotating shaft, pressure fan sends the 2nd fluid towards the circumferencial direction of the imaginary circle connected with the outer rim of impeller.In the face of the rotational axis vertical with pressure fan, multiple heat exchanger 1 is configured in pressure fan 16 around.The outside stream 8 (being represented by oblique line) of heat exchanger 1 extends on the direction that the inlet face 14 relative to heat exchanger 1 tilts.In multiple outside stream, when observing from the rotating shaft of pressure fan, the downstream of outside stream lays respectively at upstream side than outside stream more by the front in the direction of rotation of rotating shaft.The flow direction of the 2nd fluid in the outside stream 8 of heat exchanger 1 is parallel or almost parallel with the inflow direction of the 2nd fluid heat exchanger 1.That is, according to heat exchanger 1, the angle that the inflow direction of the 2nd fluid is consistent with the flow direction of the 2nd fluid in outside stream 8 or both reducing be can be made.In the front and back of the inlet face 14 of heat exchanger 1, the flow direction of the 2nd fluid changes hardly.In this case, compared with the heat exchange unit 104 of the heat exchanger 101 employed in the past, the stripping of the 2nd fluid stream can be suppressed, also be not easy to produce the large pressure loss.Therefore, it is possible to give full play to the performance of heat exchanger 1.The significantly design alteration of the housing for stationary heat exchangers 1 is not required yet.
Specifically, heat exchanger 1 has the structure of following explanation.
As shown in Fig. 2 A ~ Fig. 2 C, the outer surface of the 1st sheet material 11 is defined as the 1st interarea 11p, the outer surface of the 2nd sheet material 12 is defined as the 2nd interarea 12p.The entrance 3a of internal flow path 3 and outlet 3b is at both sides' opening of the 1st interarea 11p and the 2nd interarea 12p.Entrance 3a and outlet 3b lays respectively at end side and another side of the length direction of heat-exchange tube 2.1st sheet material 11 has the 1st entrance junction surface 4 and the 1st outlet junction surface 5.1st entrance junction surface 4 and the 1st outlet junction surface 5, as the part for being engaged with each other by adjacent heat-exchange tube 2 at entrance 3a and the outlet 3b place of internal flow path 3, are formed at the 1st interarea 11p.2nd sheet material 12 has the 2nd entrance junction surface 6 and the 2nd outlet junction surface 7.2nd entrance junction surface 6 and the 2nd outlet junction surface 7, as the part for being engaged with each other by adjacent heat-exchange tube 2 at entrance 3a and the outlet 3b place of internal flow path 3, are formed at the 2nd interarea 12p.Because heat-exchange tube 2 is engaged with each other, so do not need special attachment by the junction surface 4 ~ 7 by being formed at sheet material 11 and 12.The parts manufactured needed for heat exchanger 1 are only sheet material 11,12.Therefore, it is possible to expect the reduction of cost that realized by the reduction of number of components and the simplification of manufacturing process.
Entrance junction surface 4,6 is the protuberances of the ring-type of giving prominence to a little along the thickness direction of heat-exchange tube 2 around the entrance 3a of internal flow path 3.Outlet junction surface 5,7 is the protuberances of the ring-type of giving prominence to a little along the thickness direction of heat-exchange tube 2 around the outlet 3b of internal flow path 3.1st entrance junction surface 4 is in the position of the relative leading edge 2f near heat-exchange tube 2 with the 1st outlet junction surface 5.2nd entrance junction surface 6 is in the position of the relative leading edge 2f away from heat-exchange tube 2 with the 2nd outlet junction surface 7.1st entrance junction surface 4 engages with the 2nd entrance junction surface 6 of adjacent heat-exchange tube 2.1st outlet junction surface 5 exports junction surface 7 with the 2nd of adjacent heat-exchange tube 2 and engages.Thereby, it is possible to make multiple heat-exchange tube 2 offset with respect to each in the direction of the width.According to junction surface 4 ~ 7, the biased configuration of multiple heat-exchange tube 2 can not only be formed, the broad degree of outside stream 8 can also be specified.
In the present embodiment, the 1st entrance junction surface 4 directly engages with the 2nd entrance junction surface 6 of adjacent heat-exchange tube 2, and the 1st outlet junction surface 5 exports junction surface 7 with the 2nd of adjacent heat-exchange tube 2 and directly engages.Thus, the internal flow path 3 of adjacent heat-exchange tube 2 is communicated with.But, also as aftermentioned 3rd embodiment, coupling member can be set between junction surface 4 and junction surface 6, both are engaged indirectly.When using such coupling member, the broad degree of the outside stream 8 of regulation can be carried out by coupling member, so junction surface 4,6 can be omitted.This is also applicable to junction surface 5,7.
Amount of bias between adjacent heat-exchange tube 2 equals the amount of bias between the 1st entrance junction surface 4 and the 2nd entrance junction surface 6.By adjustment amount of bias, the angle of inclination of inlet face 14 relative to the width of heat-exchange tube 2 of heat exchanger 1 can be adjusted.In addition, in the present embodiment, amount of bias is certain.But amount of bias is not must be certain.Such as, the amount of bias between 1 group of heat-exchange tube 2 also can be different from the amount of bias between another 1 group of heat-exchange tube 2.In addition, in the present embodiment, all heat-exchange tubes 2 have identical structure.Therefore, all heat-exchange tubes 2 are biased in the direction of the width relative to adjacent heat-exchange tube 2.But, also as aftermentioned variation 5, not biased structure can be comprised partly.
1st sheet material 11 can be the component with the shape identical with the 2nd sheet material 12.When formation junction surface, position 4,5 at misalignment in the width direction, the heat-exchange tube 2 shown in construction drawing 2A ~ Fig. 2 C can be carried out by 2 the 1st sheet materials 11 of fitting.Its result, can expect the reduction of the cost realized by the reduction of number of components.
Below, some variation of heat exchanger are described.For key element common in the heat exchanger 1 shown in Fig. 2 A ~ Fig. 2 C and each variation, enclose identical Reference numeral, the description thereof will be omitted sometimes.That is, as long as not contradiction technically, the explanation relevant to heat exchanger 1 also can be applied to following variation.
(variation 1)
As shown in Figure 4 A, in the heat exchanger 1A of variation 1, multiple heat-exchange tube comprises multiple 1st heat-exchange tube 2A and multiple 2nd heat-exchange tube 2B.The structure of the 1st heat-exchange tube 2A is different from the structure of the 2nd heat-exchange tube 2B.1st heat-exchange tube 2A is adjacent in orientation with the 2nd heat-exchange tube 2B.Specifically, the 1st heat-exchange tube 2A and the 2nd heat-exchange tube 2B alternately configuration in orientation.If combinationally used by the 1st heat-exchange tube 2A and the 2nd heat-exchange tube 2B, even if then when the restriction of the broad degree equidimension of amount of bias, outside stream 8 is strict, also the easy angle of inclination by the inlet face 14 of heat exchanger 1A is adjusted to best angle.That is, according to this variation, the free degree of the design of heat exchanger 1A uprises.
1st heat-exchange tube 2A is the heat-exchange tube 2 illustrated with reference to Fig. 2 A ~ Fig. 2 C.Therefore, the explanation of the 1st heat-exchange tube 2A is omitted.
As shown in figs. 4 b and 4 c, the 2nd heat-exchange tube 2B comprises the 3rd sheet material 17 and the 4th sheet material 18 of fitting each other.The outer surface of the 3rd sheet material 17 is defined as the 3rd interarea 17p, the outer surface of the 4th sheet material 18 is defined as the 4th interarea 18p.The entrance 3a of internal flow path 3 and outlet 3b is at both sides' opening of the 3rd interarea 17p and the 4th interarea 18p.3rd sheet material 17 has the 3rd entrance junction surface 24 and the 3rd outlet junction surface 25.3rd entrance junction surface 24 and the 3rd outlet junction surface 25, as the part for being engaged with each other by adjacent heat-exchange tube 2 (the 1st heat-exchange tube 2A and the 2nd heat-exchange tube 2B), are formed at the 3rd interarea 17p.4th sheet material 18 has the 4th entrance junction surface 26 and the 4th outlet junction surface 27.4th entrance junction surface 26 and the 4th outlet junction surface 27, as the part be engaged with each other by adjacent heat-exchange tube 2 (the 1st heat-exchange tube 2A and the 2nd heat-exchange tube 2B), are formed at the 4th interarea 18p.
Entrance junction surface 24,26 is the protuberances of the ring-type of giving prominence to a little along the thickness direction of heat-exchange tube 22B around the entrance 3a of internal flow path 3.Outlet junction surface 25,27 is the protuberances of the ring-type of giving prominence to a little along the thickness direction of heat-exchange tube 2B around the outlet 3b of internal flow path 3.In the face that the orientation (Y-direction) with multiple heat-exchange tube 2A, 2B is vertical, the position at the position at the 3rd entrance junction surface 24 and the 3rd outlet junction surface 25 exports the position consistency at junction surface 27 with the position and the 4th at the 4th entrance junction surface 26 respectively.In other words, when junction surface 24 ~ 27 is projected to the plane vertical with the thickness direction of heat-exchange tube 2B, the projection image at the 3rd entrance junction surface 24 is consistent with the projection image that the projection image and the 4th at the 4th entrance junction surface 26 exports junction surface 27 respectively with the projection image at the 3rd outlet junction surface 25.According to junction surface 24 ~ 27, the biased configuration of multiple heat-exchange tube 2A, 2B can not only be formed, the broad degree of outside stream 8 can also be specified.
In this variation, the 3rd sheet material 17 is the components with the shape identical with the 4th sheet material 18.When make the 3rd sheet material 17 inside and outside to timing, the 3rd sheet material 17 and the 4th sheet material 18 completely the same.In this case, the reduction of the cost realized by the reduction of number of components can be expected.
In addition, when the 1st sheet material 11 and the 2nd sheet material 12 have different shapes, also can be the component with the shape identical with the 1st sheet material 11 or the 2nd sheet material 12 from the 3rd sheet material 17 with at least 1 side that the 4th sheet material 18 is selected.In this case, the reduction of the cost realized by the reduction of number of components can also be expected.

In this variation, heat-exchange tube 2D is made up of the 1st sheet material 41 and the 2nd sheet material 42 of fitting to be formed internal flow path 3 each other.Internal flow path 3 is that the flow direction of the 1st fluid is at the sinuous stream reverse to the midway of outlet 3b from entrance 3a.In this variation, the flow direction of the 1st fluid repeatedly (2 times) is reverse.Internal flow path 3 has the part of the odd number extended on the column direction parallel with the length direction of heat-exchange tube 2D.In this variation, internal flow path 3 comprises 3 parts parallel to each other.According to such structure, the internal diameter of inlet header 10A and outlet header 10B can be increased, so the pressure loss of the inside of inlet header 10A and outlet header 10B can be reduced.And then, can the length of width of shortening heat exchanging tube 2D, so heat exchanger 1D can be made miniaturized.
As shown in Figure 6 A and 6 B, internal flow path 3 has multiple sections that extend on the specific column direction of heat-exchange tube 2D.Specifically, internal flow path 3 has the 1st section of 51, the 2nd sections 52, the 3rd sections the 53, the 1st bending sections 54, the 2nd bending section 55, most upstream section 56 and most downstream sections 57.Heat-exchange tube 2D has outstanding to the both sides of the thickness direction of heat-exchange tube 2D, to form the section 51,52,53 of internal flow path 3 respectively multiple stream forming portions 46,47,48.Multiple stream forming portion 46,47,48 comprises the 1st stream forming portion 46, the 2nd stream forming portion 47 and the 3rd stream forming portion 48.Extend from entrance 3a along the length direction of heat-exchange tube 2D for 1st section 51.2nd section of 52 mode flowed on the direction contrary with the flow direction of the 1st fluid in the 1st section 51 with the 1st fluid extends.3rd section of 53 mode flowed on the direction contrary with the flow direction of the 1st fluid in the 2nd section 52 with the 1st fluid extends.1st section 51 is connected with the 2nd section 52 by the 1st bending section 54.2nd section 52 is connected with the 3rd section 53 by the 2nd bending section 55.Most upstream section 56 is formed in leans on upstream side and the part of the surrounding of entrance 3a than the 1st section 51.Most downstream section 57 is formed in than the 3rd section of 53 downstreams and exports the part of the surrounding of 3b.1st fluid according to entrance 3a, most upstream section 56, the 1st section 51, the 1st bending section 54, the 2nd section 52, the 2nd bending section 55, the 3rd section 53, most downstream section 57 and outlet 3b order, wriggle while flow.
In addition, heat-exchange tube 2D has the 1st thinner wall section 44 and the 2nd thinner wall section 45.1st thinner wall section 44 on the width of heat-exchange tube 2D between the 1st adjacent stream forming portion 46 and the 2nd stream forming portion 47,52 spaced by the 1st section 51 and the 2nd sections along column direction.2nd thinner wall section 45 on the width of heat-exchange tube 2D between the 2nd adjacent stream forming portion 47 and the 3rd stream forming portion 48,53 spaced by the 2nd section 52 and the 3rd sections along column direction.1st thinner wall section 44 and the 2nd thinner wall section 45 are the junction surface between the 1st sheet material 41 and the 2nd sheet material 42 respectively.
As shown in Figure 6A, in the cross section that the length direction (column direction) with heat-exchange tube 2D is vertical, the stream forming portion 46,47 of the heat-exchange tube 2D of the side selected from adjacent 1 group of heat-exchange tube 2D is across the thinner wall section 44,45 relative of outside stream 8 and the heat-exchange tube 2D of the opposing party.In addition, from thinner wall section 44,45 relative across outside stream 8 and the heat-exchange tube 2D of a side of the stream forming portion 47,48 of the heat-exchange tube 2D of adjacent 1 group of the opposing party that heat-exchange tube 2D selects.That is, multiple stream forming portions 46 ~ 48 of multiple stream forming portion 46 ~ 48 of the heat-exchange tube 2D of a side and the heat-exchange tube 2D of the opposing party are arranged in staggered on width (X-direction).According to such structure, the broad degree of the outside stream 8 on the thickness direction of heat-exchange tube 2D is roughly certain in the upper maintenance of the width (flow direction of the 2nd fluid) of heat-exchange tube 2D.Its result, can reduce the pressure loss of the 2nd fluid in outside stream 8.In addition, the stacked spacing of heat-exchange tube 2D can be reduced and expand the heat transfer area of per unit volume.And then, the stripping of the 2nd fluid stream of the surface of heat-exchange tube 2D can be suppressed and expand effective heat transfer area.
In addition, heat-exchange tube 2D also has obstruction structure, and this obstruction structure installation, between adjacent section, hinders the heat between adjacent section to move (heat between the 1st fluid specifically, flowed in each section moves).Specifically, multiple 1st through hole 44h is formed with in the 1st thinner wall section 44.Multiple 2nd through hole 45h is formed in the 2nd thinner wall section 45.1st through hole 44h constructs as the obstruction of the heat movement between obstruction the 1st section 51 and the 2nd sections 52 and plays function.2nd through hole 45h constructs as the obstruction of the heat movement between obstruction the 2nd section 52 and the 3rd sections 53 and plays function.
According to the internal flow path 3 wriggled, swim over to downstream from outside stream 8, occur thermograde on the surface of heat-exchange tube 2D.Thereby, it is possible to make the 1st fluid stream relative approx with the 2nd fluid stream, so the raising that the temperature efficiency of heat exchanger 1D can be expected and the raising of heat exchanger effectiveness of accompanying therewith.And then construct according to above-mentioned obstruction, on the width (flow direction of the 2nd fluid) of heat-exchange tube 2D, the thermograde on the surface of heat-exchange tube 2D becomes large, and temperature efficiency and the heat exchanger effectiveness of heat exchanger 1D improve further.When hindering structure to be through hole 44h, 45h, adjacent section is by spaced apart.Therefore, it is possible to reliably hinder above-mentioned heat mobile.
In this variation, the 1st through hole 44h is the through hole (specifically, slit) of through 1st thinner wall section 44 on the thickness direction of the 1st sheet material 41 and the 2nd sheet material 42.1st through hole 44h is formed in the central portion of the width of the 1st thinner wall section 44, has the shape of rectangle under overlooking.2nd through hole 45h is the through hole (specifically, slit) of through 2nd thinner wall section 45 on the thickness direction of the 1st sheet material 41 and the 2nd sheet material 42.2nd through hole 45h is formed in the central portion of the width of the 2nd thinner wall section 45, has the shape of rectangle under overlooking.Multiple 1st through hole 44h configures at predetermined spaced intervals along the length direction of the 1st thinner wall section 44.Multiple 2nd through hole 45h configures at predetermined spaced intervals along the length direction of the 2nd thinner wall section 45.
In the arbitrary cross section vertical with the thickness direction of the 2nd sheet material 42 with the 1st sheet material 41, the sectional area (total sectional area) of the 1st through hole 44h is than sectional area 1/2 large of the 1st thinner wall section 44.Interval L2 between the length L1 ratio of the length direction of the 1st through hole 44h and the 1st adjacent through hole 44h is long.In the arbitrary cross section vertical with the thickness direction of the 2nd sheet material 42 with the 1st sheet material 41, the sectional area of sectional area ratio the 2nd thinner wall section 45 of the 2nd through hole 45h 1/2 large.Interval L4 between the length L3 ratio of the length direction of the 2nd through hole 45h and the 2nd adjacent through hole 45h is long.The length L3 of the length direction of the 2nd through hole 45h is equal with the length L1 of the length direction of the 1st through hole 44h.Interval L2 between interval L4 between the 2nd adjacent through hole 45h and the 1st adjacent through hole 44h is equal.According to such structure, the heat between the 1st fluid of the 1st fluid of flowing in the 1st section 51 and flowing in the 2nd section 52 can effectively and be reliably hindered to move.Heat between effectively and reliably can hindering the 2nd section 52 and the 3rd sections 53 moves.
The shape, configuration, number, sectional area etc. of through hole 44h, 45h are not particularly limited.Such as, the shape of the 1st through hole 44h can be also other shapes such as circle, polygon, ellipse under overlooking.Also 1 the 1st through hole 44h can be only formed with in the 1st thinner wall section 44.But, when forming multiple 1st through hole 44h in the 1st thinner wall section 44 at predetermined intervals as this variation, the decline of the intensity of the 1st thinner wall section 44 can be suppressed, can effectively hinder again the heat between the 1st section 51 and the 2nd sections 52 to move.This is also applicable to the 2nd through hole 45h.
In addition, heat-exchange tube 2D also has the most upstream thinner wall section 63 the 2nd bending section 55 and most upstream section 56 separated and the 3rd through hole 63h being formed at most upstream thinner wall section 63.Most upstream thinner wall section 63 is in the thinner wall section of the 1st sheet material 41 and the 2nd sheet material 42 having been carried out being formed when fitting.3rd through hole 63h hinders to construct as the upstream side of the heat movement between obstruction the 2nd bending section 55 and most upstream section 56 and plays function.3rd through hole 63h is formed in the part near entrance 3a in most upstream thinner wall section 63.3rd through hole 63h is the through hole (specifically, slit) of through most upstream thinner wall section 63 on the thickness direction of the 1st sheet material 41 and the 2nd sheet material 42.3rd through hole 63h is formed in the central portion of most upstream thinner wall section 63, has the shape of rectangle under overlooking.According to such structure, can effectively and reliably the heat between the 2nd bending section 55 and most upstream section 56 be hindered to move.
In addition, heat-exchange tube 2D also has the most downstream thinner wall section 65 the 1st bending section 54 and most downstream section 57 separated and the 4th through hole 65h being formed at most downstream thinner wall section 65.Most downstream thinner wall section 65 is in the thinner wall section of the 1st sheet material 41 and the 2nd sheet material 42 having been carried out being formed when fitting.4th through hole 65h hinders to construct as the downstream of the heat movement between obstruction the 1st bending section 54 and most downstream section 57 and plays function.4th through hole 65h is formed in the part near outlet 3b in most downstream thinner wall section 65.4th through hole 65h is the through hole (specifically, slit) of through most downstream thinner wall section 65 on the thickness direction of the 1st sheet material 41 and the 2nd sheet material 42.4th through hole 65h is formed in the central portion of most downstream thinner wall section 65, has the shape of rectangle under overlooking.According to such structure, can effectively and reliably the heat between the 1st bending section 54 and most downstream section 57 be hindered to move.Same with the 1st through hole 44h, the shape, configuration, number, sectional area etc. of the 3rd through hole 63h and the 4th through hole 65h are not particularly limited.
The obstruction structure of heat movement is hindered to be not limited to through hole.As the obstruction structure hindering heat movement, also can with there is the material of relatively low pyroconductivity (such as, resin) make thinner wall section 44,45,63,65, the part beyond thinner wall section 44,45,63,65 is made with the material (such as, metal) with relatively high pyroconductivity.
As shown in Figure 6A, in the cross section vertical with column direction, the part (or whole) on the surface of stream forming portion 46 ~ 48 extends towards the direction that thickness direction and this both direction of width relative to heat-exchange tube 2D tilts from thinner wall section 44,45.According to such structure, when the 2nd fluid flows in outside stream 8, the stripping of the 2nd fluid of the surface of stream forming portion 46 ~ 48 can be suppressed.Therefore, the heat exchanger effectiveness of heat exchanger 1D improves further.
In this variation, only used a kind of heat-exchange tube 2D.Thereby, it is possible to expect the reduction of cost and the simplification of manufacturing process.But, also can use the heat-exchange tube of multiple kinds with structure different from each other.
(variation 4)
The quantity forming the section of internal flow path 3 is not limited to 3.As shown in Figure 7 A, the heat-exchange tube 2E that the heat exchanger 1E of variation 4 uses is having in 5 the section this point forming internal flow path 3, different from the heat-exchange tube 2D that the heat exchanger 1D of variation 3 uses.
(variation 5)
Not every heat-exchange tube all must be biased relative to adjacent heat-exchange tube in the direction of the width.As shown in Figure 7 B, the heat exchanger 1F of variation 5 is made up of multiple heat exchange nest of tubes 20.Adjacent heat exchange nest of tubes 20 is at width (X-direction) upper offset.Heat exchange nest of tubes 20 is made up of multiple heat-exchange tube 2D, 2F.Specifically, heat exchange nest of tubes 20 comprises heat-exchange tube 2D and heat-exchange tube 2F.Heat-exchange tube 2D is the heat-exchange tube that the heat exchanger 1D of variation 3 uses.Heat-exchange tube 2F is the variation of heat-exchange tube 2D.In heat-exchange tube 2F, be not biased relative to the entrance junction surface formed at the 2nd sheet material and outlet junction surface respectively at the entrance junction surface that the 1st sheet material is formed and outlet junction surface.In heat exchange nest of tubes 20, heat-exchange tube 2D is not biased relative to heat-exchange tube 2F.Like this, by by the heat-exchange tube with multiple junction surfaces biased in the direction of the width and the heat-exchange tube combination had at the not biased multiple junction surfaces of width, the angle of inclination (the inflow angle of the 2nd fluid heat exchanger) of inlet face 14 suitably can be adjusted.
(other structures)
The cross section of internal flow path 3 also can be the curve shape such as streamline shape, wing-like.In addition, all bights of comprising, the cross section of internal flow path 3 or a part of bight also can have R shape or curve shape.According to such structure, the pressure loss of the 2nd fluid can be reduced, and suppress the stripping of the 2nd fluid stream.
In addition, also can at least one end of heat-exchange tube in the direction of the width be provided with from the stream forming portion forming internal flow path 3 along the outstanding plate-like portion of width.The flow direction of such plate-like portion restriction the 2nd fluid, suppresses the stripping of the 2nd fluid stream.Thus, effective heat transfer area of heat-exchange tube increases.In addition, plate-like portion self bears the effect of fin, and the surface of plate-like portion is added as heat-transfer area.Therefore, by arranging plate-like portion at heat-exchange tube, the miniaturization of heat exchanger can be realized.
Below, the heat exchanger of other embodiments is described.For key element common in the heat exchanger of the heat exchanger illustrated in the 1st embodiment and other embodiments, enclose identical Reference numeral, the description thereof will be omitted sometimes.That is, as long as not contradiction technically, the explanation of the 1st embodiment also can be applicable to following embodiment.
(the 2nd embodiment)

Heat-exchange tube 2G has the protuberance 29 of tabular at the two ends of width (flow direction of the 2nd fluid).Protuberance 29 forms intake section 8a and the exit portion 8b of outside stream 8.Protuberance 29 contributes to the heat transfer area expanding heat-exchange tube 2G.
The intake section 8a of outside stream 8 extends on the direction that the inlet face 14 relative to heat exchanger 1G tilts, to make the flow direction of the 2nd fluid at the intake section 8a place of outside stream 8 close to the direction parallel from the direction that pressure fan (with reference to Fig. 3 B) heat exchanger 1G flows into the 2nd fluid.According to the present embodiment, can consider that the inflow angle of the 2nd fluid externally intake section 8a of stream 8 is to adjust the angle of protuberance 29.Thereby, it is possible to reduce the pressure loss of the 2nd fluid, and the stripping of the 2nd fluid stream can be suppressed.
In the present embodiment, protuberance 29 is exterior regions (or hinder marginal part) of heat-exchange tube 2G, relative to orientation (Y-direction) and width (X-direction) inclination of multiple heat-exchange tube 2G.According to such structure, the angle that the inflow direction not carrying out the direction and the 2nd fluid that significantly design alteration just can reduce the intake section 8a of outside stream 8 is.Its result, can provide a kind of heat exchanger 1G that inhibit cost, have again excellent properties.
Protuberance 29 can be formed by the bend at end of the sheet material by forming heat-exchange tube 2G.The tilt angle alpha (angle of inclination relative to width) of protuberance 29 is upper certain in the orientation (Y-direction) of heat-exchange tube 2G.But tilt angle alpha is not must be certain.Such as, when the inflow angle of the 2nd fluid heat exchanger changes in the orientation of heat-exchange tube, the inflow angle of the 2nd fluid can be coordinated and tilt angle alpha is changed.That is, in heat exchanger 1G, the protuberance 29 with various tilt angle alpha also can be formed with.
