As shown in Fig. 2 on an end of the pipe 16 and another end, formed with the width direction (arrow A1, A2 directions) constriction for Rack narrow shape a pair of insertion sections 38a, 38b.

The insertion section 38a, 38b be, for example, by by an end of pipe 16 and another end respectively towards width side Formed to central conquassation, relative to (the arrow in the width direction of the position beyond said one end and another end A1, A2 direction) equably formed with defined conquassation amount by conquassation.Thus, insertion section 38a, 38b is in pipe 16, such as Fig. 3 A It is shown, the end in the width direction in multiple streams 24 is played the 2nd stream 32a, 32b conquassation as the 2nd, in the 2nd stream On road 32a, 32b, formed with the bellying for making the wall portion 40 formed with the 2nd rib 36 be bloated respectively towards inner side with section arc-shaped 42。

That is, the 2nd stream 32a, 32b is changed into narrow compared with other streams 24, and its passage sections product is relative to other streams 24 passage sections area and reduce.

In other words, the 2nd stream 32a, 32b so that one formed with the 2nd rib 36 and another wall portion 40 it is closer to each other Mode respectively towards inner side with section arc-shaped deform and formed.

Then, as shown in Fig. 2 making insertion section 38a, 38b of pipe 16 respectively to the 1st catch box 12 and the 2nd catch box 14 Inside insertion and fixed by soldering etc., thus make inside and the pipe 16 of above-mentioned 1st catch box 12 and the 2nd catch box 14 Stream 24 connects.

As shown in figure 1, fin 18 is such as by and warpage being section corrugated by the sheet moulding aluminum, its with Relative to 2 pipes 16 being adjacent to along the width of the 1st catch box 12 and the 2nd catch box 14 (arrow B1, B2 directions) Alternately the mode of connection configures, and is formed as, with thickness direction (arrow of the undulatory cross sectional shape along heat exchanger 10 A1, A2 direction) only extend Rack.

The heat exchanger 10 of embodiment of the present utility model is substantially being formed as described above, referring next to figure 4A~Fig. 4 C illustrate the end progress dimensioned relative to pipe 16 and form insertion section 38a situation.

First, the fixture for processing 44 for dimensioned is briefly described.The fixture for processing 44 is by with insertion groove 46 A pair of blocks 48a, 48b form, the insertion groove 46 be section oblong-shaped and can be inserted into for pipe 16 thickness center, should plus Work is approached with width (arrow A1, A2 directions) of the fixture 44 along above-mentioned pipe 16, separation is set freely.

In addition, the upper shed of end face 50 relative to each other in block 48a, 48b has insertion groove 46, it is along width (arrow A1, A2 directions) is respectively formed as straight line shape, and the section of its cross sectional shape and pipe 16 with of approximately equal length Shape (section flat) is correspondingly formed.

The insertion groove 46 is formed as, and makes the length ratio of block 48a length and another block 48b length sum The width dimensions of pipe 16 are short, and the difference of the length and width dimensions turns into insertion section 38a conquassation amount.

That is, a block 48a and another block 48b is so that end face 50 relative to each other turns into symmetric figure as border The mode of shape is formed.

Next, formed by dimensioned using above-mentioned fixture for processing 44 and on an end of pipe 16 slotting Enter portion 38a, in this case, turn into the state for fixing pipe 16 by fixture (not shown) etc., and relative to one end thereof Block 48a, 48b of fixture for processing 44 is set to approach respectively on the outside of the width of pipe 16.Then, as shown in Figure 4 A, from pipe 16 width end is inserted to block 48a, 48b insertion groove 46, and makes its close direction movement to each other.By This, the width of block 48a, 48b along pipe 16 moves.

And by moving block 48a, 48b, as shown in Figure 4 B, turn into the width end of pipe 16 respectively with insertion The state of the end abutment of groove 46, by further making block 48a, 48b closer to each other from the state, and make above-mentioned width Close direction is pushed to each other for end.As a result, for example pushing force is paid respectively to the width end of pipe 16, should Pushing force is exerted a force in a manner of towards width inboard compression, and the outside of pipe 16 is limited by block 48a, 48, thus with Wall portion 40 is set to be had an effect towards the mode of deformation on the inside of thickness direction.

Thus, to pipe 16 it is paying, towards the pushing force on the inside of width in the 2nd stream 32a, 32b, to the 2nd rib 36 directions formed, discharged on the inside of thickness direction, the wall portion 40 for being consequently formed above-mentioned 2nd rib 36 is moulded in curved manner Property deformation and form bellying 42.

Finally, as shown in Figure 4 C, be moved to a block 48a and another block 48b it is against each other untill, thus pipe 16 An end only with Rack by conquassation, and the insertion section 38a formed with bellying 42 is formd, by making above-mentioned block The direction movement that 48a, 48b are separated to each other, so as to which above-mentioned pipe 16 be taken out, this completes above-mentioned insertion section 38a size Processing.

Further, since relative to another end of pipe 16 carry out dimensioned and formed insertion section 38b situation also with The above-mentioned dimensioned to an end is likewise, so omitting specific description herein.

Next, explanation includes the dynamic of the heat exchanger 10 of the pipe 16 formed with insertion section 38a, 38b as described above Make.

First, in the case where the engine in driving vehicle (not shown) makes compressor action, by (not shown) Pipe arrangement and from ingress pipe 20 import refrigerant from the 1st catch box 12 by the stream 24 of multiple pipes 16 and flow downwards and to 2nd catch box 14 imports.Then, make by multiple pipes 16 refrigeration from the 2nd catch box 14 to the 1st catch box 12 that again returned to from Agent is discharged from delivery line 22.Like this, between the 1st catch box 12 and the 2nd catch box 14, stream of the refrigerant in multiple pipes 16 Circulate in road 24, it carries out heat exchange between the air passed through from fin 18, makes the air cooled and downstream side (arrow Head A1 directions) supply.

Then, the engine stop in the state of vehicle parking, the therewith action of compressor stop, in this case, The 2nd stream 32a, 32b in one end of pipe 16 and another end is provided with bellying 42, compared with other streams 24 Passage sections area reduces, and formed with multiple 2nd ribs 36, therefore, the system circulated when driving engine in inner wall surface thereof Cryogen can be difficult to discharge from the 2nd stream 32a, 32b compared with other streams 24, so as to remain in inside.In other words, rule can be made Quantitative refrigerant is remained in the 2nd stream 32a, 32b.Thus, in the state of engine stop, if air from dissipate Pass through the cold of, the refrigerant that thus can just make to remain in the 2nd stream 32a, 32b of each pipe 16 between backing 18 and pipe 16 It can be transmitted to fin 18, so as to carry out heat exchange with air, thus air is cooled so as to which as cold wind, downstream side supplies.

That is, in the state of the stopping along with engine stops compressor, pass through from heat exchanger 10 Air also can be by remaining in each pipe 16 the 2nd stream 32a, 32b in refrigerant be suitably cooled.

As described above, in the present embodiment, have on the multiple pipes 16 for forming heat exchanger 10 along width Have multiple streams 24, formed on an end of the pipe 16 and another end and be inserted into the 1st catch box 12 and In insertion section 38a, 38b of 2nd catch box 14, shape on the 2nd stream 32a, 32b as the 2nd is played in end in the width direction Into the bellying 42 having towards inner side bulging, and multiple 2nd ribs 36 are formed on internal face.

Thus, path of the passage sections area of the 2nd stream 32a, 32b in 38a, the 38b of insertion section than other streams 24 Area of section is small, when engine stop, refrigerant can also suitably remained in as an insertion section 38a with it is another In above-mentioned 2nd stream 32a, 32b between one insertion section 38b.As a result, without as the heat exchanger of conventional art Ground, the cool storage material and cool storage material container cooled down during engine stop is provided between the tubes, it becomes possible to pass through Carry out the heat exchange between the interior refrigerants and air remained of the 2nd stream 32a, 32b of each pipe 16 and cool down air, so as to The reduction of cooling performance during suppression engine stop.

Like this, without setting cool storage material container between pipe 16, therefore part number of packages and manufacture can be sought Cut down and lightweight, and can whole pipe 16 between set fin 18, thus, it is possible to conventional heat exchanger phase Than increase refrigerant and air between heat transfer area, be additionally, since in the absence of when air between above-mentioned pipe 16 by when hinder Hinder the part of flowing, so aeration resistance can be reduced.

In addition, carry out dimensioned relative to an end of pipe 16 and another end formed insertion section 38a, During 38b, it is preferably, can simultaneously makes to deform with the wall portion 40 that the 2nd stream 32a, 32b faces and form bellying 42, therefore not The new manufacturing process for forming the bellying 42 or processing cost can be increased.

Moreover, by forming bellying 42 on the 2nd stream 32a, 32b with the 2nd rib 36, and in its without rib Passage sections area can be reduced by setting the situation of bellying 42 to compare on his stream 24, and can utilize the 2nd adjacent rib 36 Between surface tension and make refrigerant (arrow C2 directions) be mobile upward, therefore refrigerant can be made in the upper and lower of pipe 16 Equably remain upwards, so as to equably carry out heat exchange.

In addition, heat exchanger of the present utility model is not limited to above-mentioned embodiment, this can not departed from certainly Various compositions are used in the range of the purport of utility model.
