Description

Description Technical field of heat exchanger with liquid receiver Technical field The present invention relates to a heat exchanger with liquid receiver, and more specifically, an anodized aluminum alloy or an aluminum alloy. The present invention relates to a heat exchanger with a liquid receiver, which is made of aluminum, and is suitable as a heat exchanger incorporated in air conditioning equipment installed in an automobile, for example. · '

1 = 1 Scenic technology Conventionally, this type of heat exchanger is generally a pair of aluminum header pipes formed in a substantially cylindrical shape. A heat exchanger body having a plurality of heat exchange tubes erected in parallel between the header pipes and fins interposed between the heat exchange tubes adjacent to each other; The aluminum receiver body formed in the shape of an aluminum is connected and fixed to each other by an aluminum connection via an aluminum connecting member. Things are known.

Then, in such a conventional heat exchanger, the liquid receiver main body is, for example, as described in Japanese Patent Application Laid-Open No. 2002-195,701. It is manufactured as follows. That is, a foot having a shape in contact with the cylindrical portion and the header pipe. (Joint) An aluminum extruded section with a cross-sectional shape that has and is cut to the required length, and then an extra portion of the foot is left, leaving the necessary joint with the header pipe. It is formed by cutting and removing. Here, the cut part of the foot of the formed liquid receiver's body is usually the part in contact with the hot part of the header pipe (the area where the high-temperature heat medium flows). And the part where the filter and seal cap are fitted (inserted).

The reason for cutting the feet of the receiver main body in this way is that, first, the part of the header pipe that contacts the high temperature part is the amount of heat in the high temperature part of the heat exchanger main body. The heat medium (refrigerant), which has been cooled and liquefied by cooling, is re-vaporized and the cooling efficiency is reduced, so it is necessary to remove this part. Second, the area where the filter and seal cap are inserted is improved by cutting the inner diameter and uniformly expanding the inner surface of the cylindrical part to improve the sealing performance. This is for fine adjustment of inner diameter and surface roughness.

For this purpose, when forming the receiver body by cutting unnecessary parts of the feet from the extruded profile made of anore mini with this cylindrical part and feet. Because it is necessary to maintain the balance of the wall thickness when extruding the extruded section, it is necessary to make the cylindrical section of this extruded section extra thick. It is necessary to adjust the wall thickness of the inlet part of the heater and the seal cap by adjusting the wall thickness. As a result, if the weight of the receiver body is increased, there is a problem.

However, depending on the type and application of the heat exchanger, its light weight In some cases, the thickness of the cylindrical part must be reduced because of the need to reduce the weight of the receiver body and the necessity of attaching a seal cap. It is necessary to cut the cylinder and the foot, which is extremely troublesome.In addition, if the cutting part is made larger with emphasis on weight reduction, the area to be roasted becomes smaller. There is a possibility that the bonding strength will be insufficient, and if the diameter of the receiver body is changed, the design of the extruded shape must also be newly changed. There's a problem.

In addition, in the above-described conventional heat exchanger, as shown in Fig. 37, the receiver a is heat-exchanged as a connection structure between the header pipe and the receiver. A structure in which a row is directly attached to the flat part e formed on the header pipe c of the vessel b (see Fig. 37 (a)), and the receiver pipe a and the header pipe c of the heat exchanger b are connected. The structure to be roasted via the pipe f and the bracket g (see Fig. 37 (b)), the receiver pipe a and the header pipe c of the heat exchanger b are extruded It is known that a bracket (see FIG. 37 (c)) or the like is attached via a bracket h formed by opening a through-hole i serving as a pipe. However, in the connection structure shown in Fig. 37 (a), the strength and strength of the connection between the header a of the header pipe c of the receiver a and the heat exchanger b In order to obtain durability, it is necessary to increase the joint area, so this joint must be formed in a plane, and the flat part e is formed. Requires a lot of time and effort, and the part where the contact between the receiver a and the header pipe c can be formed in a plane is omitted from the input force of the tube d. The receiver is limited to 180 ° offset There is a problem S that the mounting position of a is limited to the position just beside the heat exchanger b.

In the connection structure shown in Fig. 37 (b), since the pipe f is inserted into the receiver a with the pipe f being slightly inserted, the connection is made inside the receiver a. There is a risk that the bag of the disposed desiccant j may be damaged, and the desiccant j may obstruct the flow path when the refrigerant flows into the receiver a. In addition to an increase in flow path resistance, there is a possibility that gas-liquid separation of the inflowing refrigerant may be suppressed. Also, since the supporting bracket g of the receiver a is formed separately from the pipe f, the number of parts increases and the assembling work is troublesome. There is a problem with this.

Further, in the connection structure shown in FIG. 37 (c), since the connection member h has a shape close to the block, the distance between the header pipe c and the receiver a is increased. When the distance increases, the volume and the weight of the connecting member h increase accordingly. As a result, there is a problem that the roasting property decreases and the material cost increases.

Therefore, as shown in FIG. 37 (d), a header pipe is used as a structure for solving the problems of the connection structure shown in FIGS. 37 (a) to 37 (c). It is conceivable that a plate-like connecting member k is interposed between c and the liquid receiver a, and a refrigerant flow pipe m is formed in this connecting member k by burring. It is.

ら Due to the low force S, there is a limit to the molding height of the above-mentioned pearling m, and in order to increase the height of the knurling m, the thickness of the connecting member k must be increased. It must be formed, and as the thickness of the connecting member k increases, the pressing ability of the pearling process must also be improved. There is a problem. Also the bar As the ring m is formed high, there is also a problem that the draft area decreases the flow path area and the flow resistance of the refrigerant increases. Also, since the receiver a or the connecting member k interferes with the tube d of the heat exchanger b, the mounting angle of the receiver a with respect to the header pipe c is changed. The problem arises of being limited.

Furthermore, in the conventional heat exchangers described above, for example, if the heat exchanger is used for an automobile, the installation space is limited to a narrow space in the Bonnet. For this reason, the heat transfer pipe is connected so that the heat transfer pipe can be placed very close to the header pipe of the heat exchanger. It has been practiced that a connector is attached to a header pipe by roving to form an integral part (for example, Japanese Patent No. 2,756,106, Japanese Patent Publication No. 2000-202, No. 523, JP-A-2003-021,490, etc.).

Since the connector fixed to the heat exchanger in this way from the low force S, it is manufactured by extrusion molding or forging, it is provided with an opening material layer on the surface. When connecting this connector to the header pipe, it is difficult to directly connect the connector to the header pipe by means of the mouth piece provided on the surface of the header pipe. It is attached to the header pipe, but since the thickness of the header pipe is usually as thin as about 1 mm, the connection between the connector and the header pipe is not possible. If it is complete, the header pipe attached to the connector may be damaged when the connector is subjected to a high force.

In order to strengthen the connection between the connector and the header pipe, it is necessary to increase the amount of filler material provided on the surface of the header pipe. However, the header pipe has A plurality of cooling tubes (heat exchange tubes) are connected by brazing, and the wall thickness of the cooling tubes is usually about 0.2 to 0.5 mm. In addition, if the header material on the surface of the header nope becomes unnecessarily large, erosion may occur on the surface of the cooling tube during roving. Therefore, the amount of material required for the header pipe and cooling tube to be properly roasted is determined by itself, and the amount of header pipe roasting material must be reduced. In many cases, it is not possible to set a sufficient cladding ratio to ensure the connection of the connector and the header pipe.

The present invention has been made in view of the above circumstances, so that the material can be reduced and the weight can be reduced, the manufacturing operation can be facilitated, and the main body of the liquid receiver is separated from the main body of the heat exchanger. It is also possible to provide a heat exchanger with a liquid receiver that can reduce the thermal effect to be received and that can surely and firmly perform the bonding between the heat exchanger body and the liquid receiver body. It is.

Further, the present invention provides a simplified structure of a header pipe, a receiver main body, and a connecting member, a reduction in the material of a connecting member, an improvement in a rotatable property, and a header pipe. The purpose of the present invention is to provide a heat exchanger with a liquid receiver that can increase the mounting angle of the liquid container body.

Further, the present invention provides a heat exchanger with a liquid receiver, which is capable of improving connector mounting strength and rotatable properties, reducing the number of constituent members, and reducing the number of processing steps. is there. Disclosure of the invention That is, the present invention provides a pair of aluminum header pipes, a plurality of heat exchange tubes erected in parallel with each other between the pair of header pipes, and A heat exchanger body having a fin interposed between the heat exchange tubes, and one of the heat exchanger bodies arranged along the header pipe and made of aluminum. The headano, through the connecting member of the above. And an aluminum receiver body that is connected and fixed to the lobe by mouth. A heat exchanger with a receiver, wherein the receiver body has one end force. Towards the other end, it is formed in a stepped cylindrical shape having a small-diameter cylindrical portion, an intermediate cylindrical portion larger in diameter than the small-diameter cylindrical portion, and a large-diameter cylindrical portion larger in diameter than the intermediate cylindrical portion. The receiver is connected and fixed to the liquid receiver main body and the header pipe by mouth bonding with an aluminum connecting member interposed between the liquid receiver main body and the header pipe. It is a heat exchanger with a liquid container.

In the present invention, the liquid receiver main body may be an extruded aluminum-made material having a horizontal shape such as a circular shape, a rectangular shape, a polygonal shape, an elliptical shape, a semicircular shape, and an elliptical shape. It is formed by molding a cylindrical member of a color into a stepped cylindrical shape. Preferably, a cylindrical member having a circular cross-sectional shape is subjected to press working. It is formed by molding into a stepped cylindrical shape. The length of the small-diameter cylinder, the intermediate cylinder, and the large-diameter cylinder of the receiver body is not particularly limited. However, it is preferable that at least one of the lengths be closer to the one end opening side. The filter part of the filter cap, in which the filter and the plug are integrally formed, and the seal part by the ring are the intermediate cylindrical part, and the large diameter part of the cylindrical part of the plug body is Be contained It is preferable that the desiccant is formed into a large-diameter cylindrical portion and a small-diameter cylindrical portion is formed from the other end opening side, and more desirably, the desiccant is contained in the intermediate cylindrical portion. It is advisable to design the intermediate cylinder so that its length is relatively large.

Any method can be used for pressing the cylindrical member, as long as the cylindrical member can be finally formed into a stepped cylindrical shape, but is preferably the same as that for the small-diameter cylindrical portion. A cylindrical member having a diameter is formed by extrusion molding, and then a cylindrical molding die having a larger diameter than the small-diameter cylindrical portion is press-fitted from one end opening side of the cylindrical member, and the other end of the cylindrical member is formed. The intermediate cylinder is formed by enlarging the diameter of the other part while leaving the small-diameter cylinder on the opening side, and further from the opening end side of the intermediate cylinder to the intermediate cylinder. By press-fitting a cylindrical mold with a larger diameter and leaving the intermediate cylindrical part in the middle of the cylindrical member, the diameter of the other end opening side of the cylindrical member is enlarged. The force S for forming a large-diameter tube is good. By forming the cylindrical member into a stepped cylindrical shape by pressing the cylindrical member in this way, a groove in the extrusion direction inevitably generated on the inner surface of the cylindrical member when the cylindrical member is extruded. Disappears and the surface roughness of the inner surface is improved, and when the cylindrical member is a cylindrical member and the stepped cylindrical shape is a stepped cylindrical shape, the roundness is also improved. As a result, the force S can be improved to improve the airtightness at the opening on the side of the intermediate cylinder in which the o-ring seal portion of the filter is accommodated.

In addition, by forming the receiver main body into a stepped cylindrical shape by pressing the cylindrical member in this manner, the liquid receiving body can be formed from an extruded shape having a cylindrical portion and a foot portion. Cutting unnecessary parts of the foot and the inner surface of the cylinder Significant reduction in material compared to the conventional structure At the same time, the weight can be significantly reduced, and the manufacturing operation of the receiver body can be simplified. In addition, even when the diameter of the receiver body is changed, it is possible to cope only by changing the diameter expansion in the press working. For example, when a receiver body with an outer diameter of 31.2 ra m Φ and an inner volume of 150 cc was manufactured, the pre- The weight was 156 g in the molding by, and it was possible to drastically reduce the material and reduce the weight.

Further, in the present invention, the connecting member is formed on one side surface of the substantially flat base portion such that the connecting member is relatively close to the joining surface of the header pipe (c0mp1ementa11y). ) Headano contact. A plate-shaped member on which the connecting surface on the tip side is provided, and the receiving surface on the other side is provided with the connecting surface on the receiver body side that complementarily contacts the connecting surface of the receiver body And between the heat medium outlet communication port and the heat medium communication port provided in the header pipe and the receiver main body, respectively, passing through the plate member. And a communication part for communicating with the plate-shaped member. If necessary, the plate-shaped member is joined and fixed to the above-mentioned plate-shaped member by means of a row, and one end is connected to a header pipe. The connector is provided with an aluminum connector to which the other end of the heat medium outlet pipe is connected.

Preferably, the communication portion is fitted into a through hole formed in a joint surface of the plate-shaped member on the side of the receiver main body, which is in contact with the joint surface of the intermediate cylinder portion of the receiver main body. At the same time, a pipe member that can be fitted to the outflow communication port and the inflow communication port of the heat medium provided in the header pipe and the receiver body, respectively. It is formed . As a result, even when the distance between the header pipe and the receiver body is large, it is possible to easily connect the pipe members by changing the length of the pipe members. Also, even if the length of the pipe member becomes longer, the inner diameter of the pipe member is constant, so that, for example, a draft due to pearling does not occur. Therefore, the force S can be maintained without reducing the cross-sectional area of the flow path and keeping the passage resistance constant.

Further, in the present invention, the pipe member has an end portion that fits into the through hole of the plate-shaped member formed in a tapered shape with an outward diameter, and these plate members are formed in a tapered shape. The connection between the shape member and the pipe member may be fixed by bonding. Further, at least one of the plate-shaped member and the pipe member is formed of a cladding material.

In other words, the plate-shaped member has a convex or concave portion formed at its end, and the header pipe or the receiver main body has a concave portion or a concave portion which engages with the convex portion. A convex portion may be formed to engage with the concave portion so that positioning and connection of the connecting member to the header pipe or the liquid receiver main body can be easily and reliably performed. In addition, the plate-shaped member is divided into a plurality of joint surfaces each of the joint surface on the header pipe side and / or the joint surface on the receiver main body, and the header pipe and the receiver main body are separated from each other. Even if the fixed shaft length is ensured.

Further, the plate-shaped member may be provided with a connecting step for separating the joint surface between the header pipe side and the receiver main body side. The connecting step may have an inclination angle. By forming such a connecting step, the header is increased. One pipe and the receiver body can be connected at a distance from each other, reducing heat conduction from the header pipe to the receiver body, and connecting this step. By providing an inclination angle at the bottom, vibration resistance and workability of the plate-shaped member can be improved. Furthermore, a plurality of cutouts may be formed in the side of the plate-shaped member to avoid interference with the heat exchange tubes of the heat exchanger body. Form the brackets together.

In addition, for the heat medium outflow and inflow communication ports provided in the header pipe, the receiver body is heat-exchanged in parallel with the center axis of the header pipe of the heat exchanger. When the pipe is mounted at a position that is rotated approximately 90 ° with respect to the mounting direction of the pipe to the pipe, the pipe is eccentric to the outside from the center of the header pipe. It may be provided in

Also, the joining surface of the plate-shaped member on the side of the receiver main body may be formed so as to abut the joining surface of the intermediate cylinder portion of the receiver main body. A relatively wide gap is formed between the small-diameter cylindrical part of the receiver and the small-diameter cylinder to further reduce the thermal effect of the receiver from the high-temperature part of the heat exchanger and reduce the heat exchange efficiency. It can be improved.

Furthermore, the plate-shaped member is provided with a second receiver-side main body-side joining surface that abuts complementarily on the joint surface of the receiver body, and the second receiver-side body A connector-side joint surface is provided on the back side of the main-unit-side joint surface so that the connector-side joint surface abuts mutually with respect to the joint surface of the connector. It is preferable that it is firmly attached to the receiver body. Then, the joint surfaces formed on the above-mentioned header pipe, the liquid receiver main body, and the connector, and the joint between the plate-like member and the plate-like member which is in contact with these joint surfaces, is connected to the header pipe. If one of the surfaces, the receiver body side connection surface and the connector side connection surface is a convex curved surface (concave curved surface), it will come into contact with the other surface. The joint surface of this has a concave curved surface (convex curved surface), and if one of the joint surfaces is planar, the other joint surface that comes into contact with this joint surface also becomes planar. The joints formed on these header pipes, the receiver body, the connector, and the plate-shaped member should be designed freely. can do . For example, the joining surface of the above header pipe and the joining surface of the header and the pipe that is in contact with this joining surface are formed into a curved surface, and the joining surface of the receiver main body and this joining surface are formed. The contact surface of the receiver body side may be formed in a flat surface, or the contact surface of the header pipe and the receiver body may be in contact with these joint surfaces. Both the joint surface on the header pipe side and the joint surface on the receiver body side of the plate-shaped member may be formed in a flat shape. Furthermore, the connecting surface of the connector and the connecting surface of the plate-shaped member that contacts the connecting surface on the connector side may be formed in a flat shape.

Fig. (B) is an enlarged side view (c) and an enlarged cross-sectional view (d) of a main part of (b).

The heat exchanger der Ru condenser (capacitor) is Remind as in FIG. 1, the header one Nono ⁰ I flop 2 a, 2 b to each of a pair of steel Aluminum two © arm, which Their header. For example, a plurality of heat exchange tubes 3 erected between the pipes 2a and 2b, and a heat exchange fin interposed between the heat exchange tubes 3 and integrally joined. For example, a heat exchanger body 1 (hereinafter, referred to as a capacitor body 1) having a colgate fin 4 and a liquid receiver body 11 having an aluminum receiver body 11. It is mainly composed of a vessel 10 and. In this case, the capacitor main body 1 and the liquid receiver main body 11 are integrally mounted via a connecting member 60 made of aluminum. The header pipes 2a and 2b are formed in an approximately cylindrical shape by using, for example, an extruded aluminum material, and the upper and lower ends of the header pipes are formed with an azo-resin. The cap member is made of rubber and is fixedly attached by five-color attachment. In addition, for example, one of the header pipes 2a (the left side in FIG. 1) is provided with a high-temperature heat medium inlet 2c near the upper end on the outside, and the other header 2a Near the lower end of the outer side of the pipe 2b (right side in Fig. 1), there is an outlet 2d for the heat medium. Further, as shown in FIG. 2, a communication port for outflow and inflow of the heat medium is formed on the side surface of the header pipe 2a so as to communicate with the liquid receiver 10 as shown in FIG. An outflow hole 9a and an inflow hole 9b are formed, and the liquid receiver 10 is connected to the outflow hole 9a and the inflow hole 9b via a connecting member 60 so as to communicate with the outflow hole 9a and the inflow hole 9b. The mouth is integrally attached to the header pipe 2a and laid.

A partition plate 2e is provided at about 1/3 of the upper side of the header pipe 2a, and a partition plate 2f is provided between the outflow hole 9a and the inflow hole 9b. Have been taken. In addition, a partition plate 2g is provided at a position corresponding to the lower partition plate 2f in the header pipe 2b as shown in FIG.

By arranging the partition plates 2e, 2f, and 2g on the header pipes 2a and 2b, the high-temperature and high-pressure flows into the header pipe 2a from the inflow hole 2c. The heat medium flows through the heat exchange pipe 3 in the superheated area 1A (high temperature area) above the partition plate 2e, and flows into the header pipe 2b. At this time, heat exchange is performed in a gaseous state, and the temperature of the heat medium drops. Heat medium flowing into header pipe 2b is condensed between partition plates 2e and 2f and 2g. It flows through heat exchanger tube 3 in region 1B (gas-liquid two-phase region) and flows again into header pipe 2a. At this time, latent heat is exchanged and 100. /. It changes from a gas state to a liquid state of approximately 100%. In this region, there is no temperature change accompanying the phase change. The liquid heat medium flowing into the header pipe 2a flows into the receiver main body 11 through the outlet hole 9a, and is separated into gas and liquid by the receiver 10. After that, the heat medium in the liquid state flows through the inflow holes 9b, flows through the heat exchange pipes 3 in the subcooling region 1C (subcooling region) below the partition plates 2f, 2g, and flows therethrough. Flows into dark pipe 2b. At this time, heat exchange is performed in a liquid state of the heating medium, and the temperature drops.

Further, as shown in FIG. 1 (a), the heat exchange tube 3 is formed of an aluminum extruded shape, for example, in a flat plate shape. A plurality of flow paths (not shown) of the heat medium are formed, which penetrate in the longitudinal direction, and are defined. The two ends of the heat exchange tube 3 formed in this way are arranged on the opposing sides of both the header-pipes 2a and 2b at a suitable interval and in parallel with each other. It is inserted and fixed in a slit (not shown).

As shown in Fig. 1 (a), the heat exchange fin, namely, the corrugated fin 4, is continuously formed by bending an aluminum plate material. It is formed in a corrugated shape, and is interposed between the heat exchange tubes 3 and is provided with a row.

As shown in FIG. 2, the liquid receiver 10 is, for example, a multi-stage cylindrical member formed by pressing a cylindrical member formed of an aluminum extruded shape member by press processing described later. It has a liquid receiver main body 11 formed in a shape.

In order to form the liquid receiver main body 11, as shown in Fig. 5, a cylindrical extruded member made of aluminum is cut into appropriate lengths to form a cylindrical member 11A. Prepare (see Fig. 5 (a)). Next, the cylindrical member 11A is set in a press device (not shown), and the diameter is larger than the inner diameter of the cylindrical portion (small cylindrical portion) 12 at one end toward one end of the cylindrical member 11A. The cylindrical member 11A is expanded by press-fitting the cylindrical molding die PA, and the intermediate cylindrical portion 13 connected to the small-diameter cylindrical portion 12 at the end (one end) is formed (see FIG. 5 (b)). After the intermediate cylindrical portion 13 has been formed, the cylindrical member 11A is again compressed from the other end by pressing the cylindrical molding die PB having a diameter larger than the inner diameter of the intermediate cylindrical portion 13, and the intermediate cylindrical portion 13 is further expanded.

(See Fig. 5 (c)). As a result, the liquid receiver main body 11 is formed in a multi-stage cylindrical shape having a small-diameter cylindrical portion 12, an intermediate cylindrical portion 13, and a large-diameter cylindrical portion 14 whose diameter gradually increases from one end to the other end. .

By forming the liquid receiver main body 11 as described above, the foot and the inner surface of the cylinder are extruded from a conventional aluminum extruded shape having a cylindrical portion and a foot. It is possible to reduce the material, to reduce the weight, and to simplify the production work, as compared to `` The unnecessary part is removed and the enlarged diameter part is formed at the end. '' In both cases, mass production can be achieved. The receiver Even when the diameter of the main body 11 is changed, it can be dealt with by simply changing the diameter of the press-molding dies PA and PB for the same cylindrical member 11A. .

As shown in FIG. 2, the liquid receiver main body 11 is located above the partition plate 2f in the header pipe 2a. Outflow port 18 communicating with outflow hole 9a of a is formed. Also, Headano. An inlet 19 is formed at a position corresponding to the inlet 9b of the header pipe 2a below the partition plate 2f in the pipe 2a. .

A cap 15 is closed at the open end of the small-diameter cylindrical portion 12 at one end (upper end) of the liquid receiver main body 11 formed as described above. The cap 15 is made of an aluminum member, and is fixed to the receiver main body 11 by, for example, a mouthpiece and is laid. In addition, a desiccant 42 is contained in the intermediate cylindrical portion 13.

A filter cap 40 in which a filter 30 and a plug 20 are integrally formed is fitted (inserted) into the open end of the large-diameter cylindrical portion 14. The filter cap 40 is made of, for example, a synthetic resin such as a nail cap, and a filter main body 31 is provided on an upper side thereof, and a plug body is provided on a lower side thereof. The main body 21 is arranged.

The filter main body 31 is formed in a large cylindrical shape having an appropriate gap with the inner surface of the intermediate cylindrical portion 13 of the liquid receiver main body 11, and a flange is provided at the tip of the filter main body 31. A part 32 is formed and the tip part is opened as it is, while the rear bottom face 33 also serves as the tip face of the plug 20. In addition, a window 34 is formed on the peripheral surface of the filter body 31, for example, at a position that divides the filter body 31 into four parts in the circumferential direction, and the filter body 31 receives the liquid. When the heat transfer medium is inserted into the receiver main body 11 at a predetermined position, the heat medium that has flowed into the receiver main body 11 enters the filter main body 31 through the opening at the tip end of the filter main body 31. And flows out from the windows 34 to the capacitor body 1 through the inlet 19. Further, a filter membrane 35 is provided in the window 34 of the filter body. This filtration membrane 35 is for trapping impurities contained in the heat medium, and is formed in a mesh shape by a nip, for example. .

A cylindrical portion 23 is formed. Further, an O-ring groove 25 for mounting the O-ring 24 is formed in the outer peripheral portion of the cylindrical portion 22. The ring groove 25 has a height (width) and depth large enough to fit the O-ring 24 on the outer peripheral surface of the cylindrical portion 22. In this example, two pieces are arranged along the axial direction on the outer peripheral surface of the cylindrical portion 22. When the filter cap 40 is inserted into a predetermined position in the receiver main body 11, the ring 24 connects the cylindrical part 22 to the receiver main body 11. By receiving compressive deformation between them, the two 22 and 11 are sealed.

Further, a locking circumferential groove 17 is provided on the inner peripheral surface of the lower opening 16 provided in the large-diameter cylindrical portion 14 of the receiver main body 11. . In this locking peripheral groove 17, a finlet cap 40 is locked at a predetermined position of the receiver main body 11 with a predetermined pressing force. The retaining ring 50 is adapted to be removably locked. The retaining ring 50 is formed in a C-shape, and a locking hole (not shown) is formed at each end in the circumferential direction and at a position facing each other. It has been done. The retaining ring 50 is locked (attached) to the lower opening portion 16 by, for example, being deformed by a jig or the like in a direction in which the locking holes are brought closer to each other. The diameter is reduced elastically, and in the state of the reduced diameter, the diameter is reduced within the parallel inner peripheral surface formed at the end of the lower opening 16 of the large-diameter tube 14 of the receiver body 11. It is sufficient to lock the retaining ring 50 in the locking peripheral groove 17 by inserting.

In this case, since the upper surface of the retaining ring 50 comes into contact with the bottom surface 26 of the plug body 21 in the filter cap 40, the filter cap 40 receives liquid. It can be locked at a predetermined position in the container body 11 with a desired pressing force. For this reason, the locking peripheral groove 17 is formed to be annularly concave so that the retaining ring 50 can be locked at the end of the parallel inner peripheral surface forming the lower opening 16.

The cylindrical portion 22 of the plug 20 is provided with a grip portion 27 for taking out the finhole cap 40 inserted into the liquid receiver main body 11. The grip portion 27 has a rectangular shape or a cross shape formed by hanging down to the cylindrical portion 23 at the center of the lower surface of the cylindrical portion 22. When the filter cap 40 is removed from the receiver main body 11, the grip portion 27 is gripped by a tool (not shown), and is held in the gripped state. By being pulled out downward, the filter cap 40 in which the stopper 20 and the filter 30 are integrally formed is received. Fluid body 11 can be taken out from the car. Note that the desiccant 42 contained in the receiver main body 11 is made of a gel (not shown) such as silica gel (not shown) in a bag formed by polyester fibers. It is shaped like a rod like an elliptical cylinder by packing the moisture absorbing means.

In order to assemble the liquid receiver 10 configured as described above, the capacitor body 1 and the liquid receiver body 11 must be joined by fixing them together by soldering, and then first. Then, the desiccant 42 is introduced into the receiver main body 11, and then the filter 30 and the stopper 20 are applied to the receiver main body 11. Insert the tap 40 from the filter 30 side.

After the filter cap 40 has been inserted, the retaining ring 50, which has been elastically reduced in diameter, is further inserted into the parallel inner peripheral surface from the lower opening 16. When the diameter reduction of the retaining ring 50 is released at the position of the locking peripheral groove 17, the retaining ring 50 receives an elastic restoring force. At the same time as fitting, it comes into contact with the bottom surface 26 of the plug 20.

As a result, the plug 20 and the filter cap 40, which serves as a filter, are locked to the receiver main body 11 at a predetermined pressure. State can be maintained.

In the third embodiment, the connecting member 60B, the header pipe 2a, and the receiver main body 11 are separated from each other so as to be joined by roving. That is, as shown in Figs. 12 and 13 In addition, the plate-shaped member 6B constituting the connecting member 60B is in contact with the joint surface of the receiver main body 11, the second and third joint surfaces 62, 63 having an arc-shaped cross section, and the joint surface of the header pipe 2a. This is the case where the first and fourth joint surfaces 61 and 64 having an arc-shaped cross section that come into contact with are formed.

Also, between the second joint surface 62 and the first joint surface 61 of the connecting member 60B (plate-like member 6B), between the first joint surface 61 and the third joint surface 63, A connecting step 69 is formed between the third joining surface 63 and the fourth joining surface 64 so as to separate each joining surface. As shown in the figure, for example, an inclination angle Θ is provided with respect to a line perpendicular to the second and third joint surfaces 62 and 63. In this case, a slit 66 for facilitating the bending process is formed at the bent portion forming the connecting step portion 69 in the plate-shaped member 6B (see FIG. 14 and Figure 15).

As shown, a plurality of notches 8 are formed to avoid interference with the heat exchange tube 3 of the capacitor body 1. These notches 8 are formed on both sides of the plate member 6B, and each notch 8 has a width slightly larger than the thickness of the heat exchange tube 3. It is formed in a substantially U-shape. In addition, a mounting bracket 81 is formed on the connecting member 60B (plate-like member 6B). For example, Remind as in FIG. 1 6及Pi Figure 1 7, coupling member ⁶ 0 B to the bonding surface 64 of the (plate-like member 6 B) in contact only that fourth connecting member 60 B (plate-like member 6 B ), And a mounting bracket 81 having a mounting hole 82 formed substantially in the middle thereof is formed integrally by bending.
