Stacked in the middle In addition, the projections 7b and 7b are bent inward at both ends in the longitudinal direction of the tube plate 8 and fixed in a state of being close to or in contact with the longitudinal end of the tank plate 8, and the claw portion. 7g and 7g are clamped and fixed to the outside of the tank plate 8 so that they are partitioned by the first to fourth partition plates D1, D2, D3, and D4 inside the header 4 as shown in FIG. Three second chambers R2, fourth chamber R4, and fifth chamber R5 are formed.

[0028] The header 5 is configured in a substantially bilaterally symmetric shape with the header 4 described above, and similarly to the header 4, the three first chambers R1 and R1 divided by the fifth to eighth partition plates D5 to D8 are included therein. In addition to the formation of the third chamber R3 and the sixth chamber R6, the connector P1 is provided in communication with the first chamber R1, and the connector P2 is provided in communication with the sixth chamber R6.

[0029] The core section 6 is composed of a plurality of tubes 6a that are threaded through and fixed to the tube plate holes 7c of the headers 4 and 5 corresponding to both ends, and a plurality of fins 6b that are alternately arranged with the tubes 6a. The upper and lower ends of the upper and lower ends are connected and reinforced by a pair of reinforcements 10a and 10b that are threaded through and fixed to the reinforcement holes 7d of the headers 4 and 5, respectively.

[0030] As shown in FIGS. 6 and 7, the coupling member 3 has a function of fixing and supporting the receiver tank 2, and the fourth chamber R4 and the fifth chamber R5 of the header 4 are connected to the interior of the receiver tank 2. The joint member 11 and the adapter member 12 are also used.

As shown in FIGS. 8 and 9, the joint member 11 is formed in a substantially cylindrical shape with a bottom as a whole by joining the first divided member 13 and the second divided member 14 together.

In addition, an adapter member connection portion 1 la into which a reduced diameter portion 12d of the adapter member 12 described later can be inserted is formed at the opening end portion of the joint member 11, and the bottom portion 1 lb is formed in a gentle R shape. Has been.

Both divided members 13 and 14 are each formed in a substantially semi-cylindrical shape with a bottom, and can be inserted into the corresponding communication holes 8b and 8c of the tank plate 8 in the side portion 13a of the first divided member 13, respectively. The header connecting portions 13b and 13c having a functional elliptical cross section are formed so as to be spaced apart from each other in a state of protruding sideways.

Further, the header connecting portions 13b and 13c are formed in elliptical cross sections corresponding to the corresponding communication holes 8b and 8c, respectively, and step portions 13d formed by vertical surfaces are formed on the respective base end sides. Has been. In the heat exchanger with a receiver tank according to the first embodiment, the second divided member 14 is overlapped on the inner side of the first divided member 13, and the outer sides of the first divided member 13 are substantially outward. One of the lower surfaces of the fitting parts 13e, 13e (corresponding to positioning means) and the bottom part 13f refracted in an L shape, one of both edges 14a, 14a (corresponding to positioning means) and the bottom face 14b The lower surfaces of the parts are joined as joints of the two divided members 13 and 14, respectively. In the present embodiment, there is a force where there is a portion where a part of both edge portions 14a, 14a of the second divided member 14 does not contact the fitting portions 13e, 13e.

[0032] The divided members 13 and 14 are press-formed products formed by press-forming aluminum plate materials having a thickness of about 1 to 2 mm with a die not shown.

The header connection portions 13b and 13c are formed by punching press molding accurately because the leading ends of the header connection portions 13b and 13c are punched and opened during the press molding process.

In addition, the material, thickness, and the like of both the divided members 13 and 14 can be set as appropriate. For example, the first divided portion 13 may be set to be thicker than the second divided member 14.

Therefore, although the first divided member 13 has both the connecting portions 13b and 13c and has a complicated shape, the first divided member 13 can be manufactured easily and inexpensively in a short time, so that the manufacturing cost can be kept low. In addition, since extrusion and cutting are not used, there is no material left in the extra part, and compact and light weight can be realized.

[0033] The first divided member 13 and the second divided member 14 can also be manufactured by forging or forging.

[0034] The adapter member 12 is integrally formed in a substantially cylindrical shape, and an annular seal groove 12a to which the seal member S1 is attached is formed inside the upper portion thereof. A female screw groove 12b is formed in a predetermined range in the vicinity below.

Further, a reduced diameter portion 12d having a stepped portion 12c and having a reduced diameter is formed in the lower portion of the adapter member 12.

The material and thickness of the adapter member 12, the positions where the grooves 12a and 12b are formed, the formation range, and the like can be appropriately set.

[0035] Further, the adapter member 12 is formed by machining an aluminum columnar block material with a lathe or the like into a cylindrical shape with a thickness of about 1 to 2 mm, and then cutting both grooves 12a and 12b. The

Accordingly, since the adapter member 12 is not complicated, it can be easily manufactured by a relatively simple operation.

As shown in FIG. 1, the receiver tank 2 includes a cylindrical main body 2a, a substantially disc-shaped lid member 2b that closes the upper end of the main body 2a, and a substantially cylindrical connecting pipe attached to the lower end. 15, and internal structures such as a desiccant and a filter (not shown) are accommodated in the main body 2a.

Further, as shown in FIG. 10, a flange portion 15a is formed on the outer periphery of the connecting pipe 15 attached to the lower end of the main body 2a so as to expand radially outward and come into contact with the lower end of the receiver tank 2. In both cases, a male screw groove 15b is formed in a predetermined range below the flange portion 15a.

[0037] Further, a seal groove 15c fitted with an annular seal member S2 for sealing both the flange portion 15 and the main body 2a is formed, and spaced apart vertically below the groove 15b. The positions are formed with seal grooves 15d and 15e in which the seal members S3 and S4 are mounted.

[0038] Then, as shown in FIG. 11, the connecting portions 8b and 8c of the joint member 11 are fixed in a state where the corresponding connecting portions 13b and 13c for the joint member 11 are inserted into the communication holes 8b and 8c of the tank plate 8 of the header 4, respectively. Further, the adapter member connection portion 11a of the joint member 11 is fixed in a state where the step portion 12d of the adapter member 12 is inserted.

[0039] Furthermore, the receiver tank 2 is fixed in a state where the groove 15b of the connection pipe 15 of the receiver tank 2 is screwed into the groove 12b of the adapter member 12.

Further, the sealing performance between the connecting pipe 15 and the adapter member 12 is secured by the sealing members S1, S3, and S4.

[0040] Accordingly, the receiver tank 2 is detachably fixed to the adapter member 12, and the fourth chamber R4, the fourth chamber 4 of the header 4 via the connection portions 13b, 13c of the adapter member 12 and the joint member 11. 5 rooms are in communication with R5.

[0041] In addition, in the heat exchanger HA with a receiver tank according to the first embodiment, all the constituent members are made of aluminum, and at least one of the contact portions of the constituent members is a clad layer that also has a brazing filler metal. (Brazing sheet) is provided!

[0042] Next, the assembly of the heat exchanger with a reserve tank according to the first embodiment will be described.

When manufacturing the heat exchanger with a receiver tank configured as described above, first, after the heat exchanger body 1 is temporarily assembled, as shown in FIG. 12, the header connecting portion 13b of the first divided member 13 is used. , 13c are inserted into the corresponding communication holes 8b, 8c of the tank plate 8 of the header 4, and the stepped portions 13d of the header connecting portions 13b, 13c are in contact with the outer peripheral surface of the tank plate 8. And

Next, as shown in FIGS. 12 and 13, a substantially elliptical columnar jig 20, 20 having a stepped portion 20a whose diameter is increased outward in the radial direction is used for the header from the opening side of the first divided member 13, respectively. The header connecting portions 13b and 13c are inserted into the connecting portions 13b and 13c, and the inner force is expanded to the outside, so that the connecting holes 8b and 8c are swaged and fixed.

At this time, the step portions 20a of the jigs 20 and 20 abut against the inner side of the step portions 13d of the header connection portions 13b and 13c and are pressed toward the tank plate 8, thereby the header connection portions 13b and 13c. With the respective step portions 13d in close contact with the outer peripheral surface of the tank plate 8, the header connection portions 13b and 13c can be fixed by crimping them into the communication holes 8b and 8c.

Note that the header connecting portions 13b and 13c may be plastically deformed and caulked so as to increase in diameter toward the tip side.

Therefore, it is possible to easily insert the jig 20 that also needs a jig for fixing the tank plate 8 with the opening side force of the first divided member 13 to expand the diameter of the header connecting portions 13b and 13c. Good workability.

Further, the stepped portions 13d of the header connecting portions 13b and 13c abut against the outer peripheral surface of the tank plate 8, so that the insertion allowance of the header connecting portions 13b and 13c into the communication holes 8a and 8b can be easily positioned. I can decide.

In addition, before temporarily assembling the tank plate 8 to the heat exchanger body 1, the first dividing member 13 can be fixed in advance as described above. In this case, the jig 20 can be inserted from the inside of the tank plate 8 and the header connection parts 13b, 13c can be fixed by being crimped to the communication holes 8b, 8c.

[0045] Next, the second divided member 14 is overlapped inside the first divided member 13 in the middle, and the joint portion After the material 11 is temporarily fixed, the reduced diameter portion 12d of the adapter member 12 is inserted into the adapter member connection portion 11a.

At this time, the fitting portions 13e and 13e of the first divided member 13 and the both edge portions 14a and 14a of the second divided member 14 are fitted, and thereby, both can be fixed in a properly positioned state.

[0046] Next, the heat exchanger body 1 on which the both divided members 13 and 14 and the adapter member 12 are temporarily fixed is transported to a heating furnace (not shown) and heat-treated, so that the joint portions of the constituent members are brazed. Fix it.

[0047] At this time, in Example 1, brazing material is provided on the inner surfaces of the first divided member 13 and the second divided member 14, and both the divided members 13, 14 and the adapter member 12 are brazed and fixed together. Therefore, consideration is given to fixing each of these three contact portions with a small amount of brazing material.

In addition, the site | part which sets a brazing material can be set suitably, for example, you may provide a brazing material in the adapter member 12. FIG.

[0048] In addition, since the two divided members 13, 14, in particular, the first divided member 13 that is in direct contact with the tank plate 8, are press-molded and have a light weight and a low thermal mass, the tank during brazing and fixing Stable brazing and fixing can be realized by reducing the thermal effect on the plate 8.

[0049] Further, the header connecting portions 13b and 13c of the joint member 11 project in a cylindrical shape toward the header 4 so that a space O is formed between the outer peripheral surface of the header 4 and the header connecting portions 13b and 13c. (See Fig. 11), it is possible to reduce the contact area between these two as much as possible, and to achieve a smooth rise and fall of the header 4 during brazing and fixing.

[0050] Further, in addition to the stepped portions 13d of the header connecting portions 13b and 13c being in contact with the outer peripheral surface of the tank plate 8, the header connecting portions 13b and 13c of the joint member 11 have an elliptical cross section. Compared to the case of a circular cross section, the joint member 11 and the adapter member 12 can be stably fixed during and after brazing.

[0051] Next, the groove 15b of the connecting pipe 15 of the receiver tank 2 is screwed into the groove 12b of the adapter member 12, and the lower end of the flange portion 15 is brought into contact with the upper end portion of the adapter member 12. To complete the manufacture of heat exchanger with receiver tank.

At this time, the screwing operation can be performed by applying a tightening tool to the flange portion 15a of the connecting pipe 15 of the receiver tank 2 and rotating it, and the brazing material of the peripheral member is cracked or broken. There is no risk of damage.

Further, since the lower end of the flange portion 15 abuts on the upper end portion of the adapter member 12, excessive tightening of the connecting pipe 15 to the adapter portion 12 can be prevented.

Accordingly, the receiver tank 2 can be easily attached to and detached from the adapter member 12, and the type and size of the receiver tank 2 can be easily designed and changed according to the type and core size of the heat exchanger main body 1.

Further, when the receiver tank 2 is damaged, it can be removed from the adapter member 12 for replacement and repair is excellent.

[0052] Next, the operation of heat exchange with a receiver tank according to the first embodiment will be described.

After the heat exchanger with a receiver tank configured as described above was mounted on a vehicle, the compressor side force (not shown) also flowed into the chamber R1 of the header 5 via the connection hole 16a of the connector P1 (see FIG. 1). The distribution medium of about 70 ° C is a vehicle running wind passing through the core section 6 while passing through the tubes 6a corresponding to the first chamber R1 and the second chamber R2 of the core section 6, or forced wind and fins by the fan. After heat exchange via 6b, it flows into the second chamber R2 of the header 4.

[0053] The distribution medium in the second chamber R2 flows through the tubes 6a5 corresponding to the second chamber R2 and the third chamber R3 of the core portion 6 and flows into the third chamber R3 of the header 5. Next, the distribution medium in the third chamber R3 is generated by the vehicle running wind or fan passing through the core portion 6a while flowing through the tubes 6a corresponding to the third chamber R3 and the fourth chamber R4 of the core portion 6. After heat exchange with forced air, it flows into the fourth chamber R4 of the header 4.

[0054] Next, the flow medium in the fourth chamber R4 flows into the main body of the receiver tank 2 from the connection portion 13b of the joint member 11, and is separated into gas and liquid by an internal structure (not shown), and then connected to the connection portion. It flows into the room R5 from 13d.

[0055] Next, the liquid circulation medium in the fifth chamber R5 passes through the core portion 6 while flowing through the tubes 6a corresponding to the fifth chamber R5 and the sixth chamber R6 of the core portion 6. Or by heat exchange with the forced air by the fan, it is supercooled to about 45 ° C and flows into the sixth chamber R6 of the header 5.

[0056] Finally, the distribution medium in the sixth chamber R6 is discharged from the connection hole 16b of the connector P2 to the evaporator side outside the figure, and as a result, as shown in FIG. 1 is room 1 Rl ~ It functions as a condenser divided into an upper condensing part El corresponding to the fourth chamber R4 and a lower supercooling part E2 corresponding to the fifth chamber R5 and the sixth chamber R6.

[0057] Next,

As described above, in the heat exchanger with a receiver tank of the first embodiment, a plurality of tubes 6a whose both ends are connected to both headers 4 and 5 are arranged between the pair of headers 4 and 5. The heat exchanger body 1 and the heat exchanger body 1 are divided into a condensing part E1 and a supercooling part E2 by dividing the inside of both headers 4 and 5 by first to eighth partition plates D1 to D8. In a heat exchanger with a receiver tank 2 having a receiver tank 2 connected to the condensing part E1 and the supercooling part E2 of one header 4 via the connecting member 3, the connecting member 3 is connected to the condensing part of the one header 4. E1 and joint member 11 having header connection parts 13b and 13c connected in communication with supercooling part Ε2, and this joint member 11 and receiver tank 2 are connected in communication, and receiver tank 2 is detachably fixed. Adapter member 12 and joint member 11 with both header connecting parts 1 3b and 13c. Since the first divided member 13 and the second divided member 14 joined to the first divided member 13 are formed, the receiver tank can be detached and the material can be left in a portion not necessary for the function. It is possible to reduce the manufacturing cost and weight of the coupling member that couples the receiver tank and the heat exchanger body by suppressing the increase in weight.

[0058] Further, in the above heat exchanger HA with a receiver tank, since at least the first divided member 13 is a press-formed product of a metal plate material, the coupling member 3 can be manufactured more easily and inexpensively. Can do.

[0059] Further, since the header connecting portions 13b and 13c are formed on the first divided member 13, the brazing property and the header connecting portions 13b and 13c are separated from each other. Sealability can be improved and product reliability can be improved.

In addition, since the joint portion between the two divided members 13 and 14 is formed at a position away from the header 4, even when a crack or breakage occurs in the joint portion, the workability when repairing is good.

[0060] Also, the first divided member 13 and the second divided member 14 are each formed into a substantially semi-cylindrical shape with a bottom, and these are joined together to form the joint member 11 with a substantially cylindrical shape with a bottom. Since the adapter member connecting portion 11a is formed at the open end of the joint member 11 so that the adapter member 12 is connected in communication, the adapter member 12 and 14 are joined together. The connecting member 11a can be formed.

Since it is not necessary to cover the bottom of the joint member 11 with a separate lid member or the like, the number of parts can be reduced and the cost can be reduced.

[0061] Further, communication holes 8b and 8c are formed in the condensing part E1 and the supercooling part E2 of one header 4, respectively, and both header connection parts 13b and 13c protrude in a cylindrical shape toward the one header 4 side. In this state, a step portion 13d having a surface perpendicular to the base end side of both header connecting portions 13b and 13c is formed, and both header connecting portions 13b and 13c are inserted into corresponding communication holes 8b and 8c, respectively. In addition to being fixed in a state, the stepped portion 13d is brought into contact with the outer peripheral surface of one header 4, so that both header connecting portions 13b, 13c can be fixed in a state of being positioned with respect to the header 4, and the contact area between the two It is possible to fix the receiver tank firmly and to support the receiver tank stably.

[0062] Further, since both header connecting portions 13b and 13c have an elliptical cross section, the contact area with the header 4 can be increased, and the joint member 11 and the adapter member 12 can be stably fixed.

[0063] Further, since the space O is formed between the header connecting portions 13b, 13c and the outer peripheral surface of one header 4, the heat effect received by the header 4 during brazing and fixing is reduced and stable. Can be brazed.

[0064] Since the first split member 13 and the second split member 14 are provided with positioning means (fitting portions 13e, 13e, both edge portions 14a, 14a) for positioning the first split member 13 and the second split member 14, the first The divided member 13 and the second divided member 14 can be fixed in a properly positioned state.

As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments, and design changes and the like within the scope of the present invention are not included in the present invention. It is.

For example, in the first embodiment, the two divided members 13 and 14 are press-formed products, but only the first divided member 13 may be a press-formed cache product.

[0066] Further, the portion where the brazing material (brazing sheet) of each component described in the first embodiment is provided can be set as appropriate.

Industrial applicability
