Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION A condenser provided with a liquid tank according to the present invention is installed in series between a compressor and an evaporator of a vapor compression refrigerator forming an automobile air conditioner. Then, after the refrigerant compressed by the compressor is radiated and condensed, the foreign matters such as water are removed and then sent to the evaporator.

2. Description of the Related Art A vapor compression refrigerator is incorporated in an automotive air conditioner for cooling and dehumidifying the interior of an automobile.
FIG. 7 is a circuit diagram showing a basic configuration of a vapor compression refrigerator described in Japanese Patent Application Laid-Open No. 4-95522. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 exchanges heat with the air while passing through the condenser 2 to lower the temperature and become condensed and liquefied. The resulting liquid refrigerant is temporarily stored in the liquid tank 3 and then the expansion valve 4
Is sent to the evaporator 5 via the
Evaporate in. Since the temperature of the evaporator 5 decreases due to the deprivation of latent heat of vaporization, the flow of air for air-conditioning through the evaporator 5 reduces the temperature of the air and simultaneously removes the water vapor contained in the air. Can be. The refrigerant evaporated and vaporized in the evaporator 5 is sucked by the compressor 1 and compressed, and the cycle is repeated again.

A liquid tank 3 constituting such a vapor compression refrigerator of an air conditioner for an automobile is conventionally provided with a condenser 2
And a pipe made between the condenser 2 and the evaporator 5. However, when the liquid tank 3 and the capacitor 2 are separately configured as described above, not only the space for installing the liquid tank 3 is increased, but also the liquid tank 3 is sufficiently vibrated independently of the capacitor 2. It is necessary to attach it to the vehicle body with certain characteristics.

In order to solve such a trouble, conventionally, a structure in which the liquid tank 3 and the condenser 2 are integrally formed is disclosed in JP-A-3-87572 and JP-A-4-103973.
Various proposals have been made as described in JP-A No. 4-131667 and the like. FIG. 8 shows the structure described in Japanese Patent Application Laid-Open No. 4-103973. The condenser 2 has a pair of header pipes 6a and 6b which are arranged in the vertical direction (vertical direction in FIG. 8) and are separated from each other in the horizontal direction (horizontal direction in FIG. 8). A plurality of flat heat transfer tubes 7 are provided between the pair of header pipes 6a and 6b. The plurality of flat heat transfer tubes 7, 7 are arranged in the horizontal direction so as to be separated from each other in the vertical direction. And each of these flat heat transfer tubes 7, 7
Both ends of the pair of header pipes 6a, 6a
b is airtightly and liquid-tightly penetrated, and the respective inner flow paths are made to communicate with the inner side of each of the header pipes 6a and 6b. The core portion 9 is formed between the flat heat transfer tubes 7 vertically adjacent to each other by sandwiching corrugated fins 8 formed of zigzag thin metal plates. Side plates 10 and 11 are provided on the upper and lower sides of the core portion 9, respectively.
0 and 11 are connected to the header pipe 6a,
6b is fixedly connected to the inner surfaces of the upper and lower ends.

In the condenser 2 having the above-mentioned structure, the refrigerant flowing in the flat heat transfer tubes 7 and the air flowing outside the flat heat transfer tubes 7 and 7 exchange heat in the core 9. The refrigerant is condensed and liquefied. That is, the gaseous refrigerant sent from the inlet pipe 12 provided on the upper part of the one (right side in FIG. 8) header pipe 6a and the other (left side in FIG. 8) header pipe 6b While flowing back and forth, the gas flows through the flat heat transfer tubes 7 constituting the core portion 9 and condensed and liquefied during the flow. The resulting liquid refrigerant accumulates at the lower end of the one header pipe 6a and is sent from the refrigerant transfer pipe 13 to the liquid tank 3.

On the other hand, the liquid tank 3 is fixed to the outer surface of the one header pipe 6a. That is, the cylindrical case body 14 constituting the liquid tank 3 is fixed to the side surface of the header pipe 6a by brazing or the like. The lower end opening of the case body 14 is closed by a bottom plate 15, and the upper end opening is closed by an upper plate 16. The refrigerant transfer pipe 13 is made to penetrate the bottom plate 15,
This refrigerant transfer pipe 13 is inserted into the center of the case body 14. Accordingly, a cylindrical space 1 is provided between the outer peripheral surface of the refrigerant transfer pipe 13 and the inner peripheral surface of the case body 14.
8 are formed. In addition, a large number of small holes 17, 17 are formed in the upper end of the refrigerant transfer pipe 13 and above the case body 14, and the small holes 17 are fed into the refrigerant transfer pipe 13 from the header pipe 6a. The liquid refrigerant can be discharged freely. A filter 19 for collecting and removing foreign matter such as dust, and a desiccant 20 such as silica gel and calcium chloride are formed in the middle part of the space 18 in order from the bottom. And a porous holding plate 21 such as a wire mesh or a punched metal are provided in series with each other. The filter 19 and the desiccant 20 constitute a removing means for removing foreign matter mixed in the refrigerant. Further, an outlet pipe 22 is provided at the lower end of the case body 14 so that the liquid refrigerant accumulated at the lower end of the space 18 can be taken out.

When the condenser having the liquid tank constructed as described above is used (when the vapor compression refrigerator having the condenser having the liquid tank is operated),
The refrigerant flowing as shown by the arrow in FIG. 8 is condensed and liquefied in the condenser 2 and then fed into the liquid tank 3. Then, the clean refrigerant from which water and foreign substances have been removed in the liquid tank 3 is sent out from the outlet pipe 22 toward the expansion valve 4 (see FIG. 7) immediately before the evaporator 5.
The condenser having the liquid tank configured and functioning as described above can handle the condenser 2 and the liquid tank 3 integrally, so that the condenser 2 can be easily installed in a limited space inside the engine room, and the condenser 2 and the liquid tank 3 can be easily installed. Since it is not necessary to independently secure vibration resistance with the tank 3, the installation work can be facilitated.

Further, Japanese Patent Laid-Open No. 7-159000 discloses a structure in which one header pipe and the case of a liquid tank are integrally formed by an extrusion molding material. In the case of the structure described in this publication,
The case portion of the liquid tank is offset to the front side with respect to the header pipe portion of the extruded material.

[0009]

However, in the case of the conventional condenser having the liquid tank configured and operating as described above, it becomes difficult to dispose the condenser having the liquid tank immediately before the radiator. That is, the condenser 2 that constitutes a vapor compression refrigerator for an automobile air conditioner is often arranged immediately in front of a radiator for radiating cooling water and close to the front surface of the radiator. On the other hand, the outer diameter of the case body 14 that constitutes the liquid tank 3 is considerably larger than the outer diameter of the header pipe 6a that fixes the case body 14. For this reason, the rear portion of the liquid tank 3 projects rearward from the rear rear surface of the condenser 2 as it is. As a result, the liquid tank 3 interferes with the radiator, making it difficult to dispose the condenser 2 close to the front surface of the radiator immediately before the radiator for cooling water radiation.

In the case of the structure described in Japanese Patent Laid-Open No. 7-159000, the above problem does not occur, but the following problem occurs instead. That is, generally, a removing means for removing foreign matter mixed in the refrigerant is provided inside the case constituting the liquid tank. However, such a removing means is provided in the case made of an integrally extruded material. It is difficult to support. Therefore, in order to obtain the structure including the liquid tank having the removing means, it is necessary to perform troublesome processing, which increases the manufacturing cost of the capacitor including the liquid tank. Furthermore, since the combined state of the header tank and the liquid tank is uniquely restricted by the shape of the integrally extruded material, there is no design freedom. The capacitor provided with the liquid tank of the present invention was invented in view of such circumstances.

[0011]

A condenser provided with a liquid tank according to the present invention has a pair of left and right header pipes, each of which extends horizontally in the same manner as the condenser provided with a conventional liquid tank described above. A condenser provided with a plurality of heat transfer tubes arranged at both ends and opened inside the header pipes, and a fin provided between heat transfer tubes vertically adjacent to each other, and the pair of headers One of the pipes is composed of a liquid tank arranged in parallel with and supported and fixed to the one header pipe, and a refrigerant inlet of the liquid tank and a refrigerant outlet of the condenser communicate with each other. .

Particularly, in the condenser provided with the liquid tank of the present invention, the liquid tank is provided with a case independent of the header tank, and foreign matter mixed in the refrigerant is removed inside the case. And a center axis of the case is located in front of the center axis of the one header pipe. still,
In the present specification, the front side refers to the front side in the traveling direction in the state of being mounted on a vehicle, in other words, the side opposite to the radiator that is disposed in the vicinity of the capacitor.

[0013]

In the condenser provided with the liquid tank of the present invention configured as described above, since the rear portion of the liquid tank does not project rearward from the rear rear surface of the condenser, the condenser provided with the liquid tank is placed immediately before the radiator. It is easy to place. In other words, the automobile design becomes easier. Further, since the liquid tank has a case independent of the header tank, the process of assembling the removing means in the liquid tank becomes easy, and the manufacturing cost of the capacitor having the liquid tank does not increase.

Further, the liquid tank 24 comprises a cylindrical case 35 whose upper end is closed by an upper lid 45, and a mounting block 36 fixed to the lower end of the case 35. The mounting block 36 is the same as the connection block 31.
It is removable with respect to. That is, a pair of upper and lower screw holes are formed in the flange 50 formed in the connection block 31, and a pair of upper and lower through holes are formed in a portion of the mounting block 36 that is aligned with these screw holes.

Further, the upper portion of the case 35 is joined and fixed to the upper portion of the one header pipe 26a by the spacer 43 and the restraining belt 44. That is, with the spacer 43 made of an aluminum material, a synthetic resin or the like being sandwiched between the upper outer surface of the header pipe 26a and the upper inner surface of the case 35, the restraining belt 44 secures the header pipe 26a. The upper part and the upper part of the case 35 are bundled.

When a condenser equipped with the liquid tank of the present invention constructed as described above is incorporated in a vapor compression refrigerator, a refrigerant communicating with the compressor 1 (FIG. 7) is introduced into an inlet port provided in the inlet block 32. The downstream end of the pipe
The upstream ends of the refrigerant pipes leading to the evaporator 5 (FIG. 7) are connected to the outlet ports provided in the outlet block 37, respectively. When the compressor 1 is operated in this state, the condenser equipped with the liquid tank of the present invention condenses the refrigerant discharged from the compressor 1, supercools it, and then sends it to the evaporator 5.

The refrigerant gas sent from the inlet port provided in the inlet block 32 to the condenser 23 is passed through the heat transfer tubes 28, 28 constituting the condenser 23.
It flows while turning back between a pair of header pipes 26a and 26b. During this time, the refrigerant gas exchanges heat with the air passing between the heat transfer tubes 28, 28 and the fins 34, 34 to be condensed and liquefied. The liquid refrigerant generated as a result is sent from the discharge port provided in the connection block 31 to the intake port 39 provided in the mounting block 36 constituting the liquid tank 24. The liquid refrigerant thus sent to the intake port 39 is sent to the upper part of the case 35 through the refrigerant transfer pipe 42 and then flows down inside the case 35. Then, while the water and foreign substances mixed in the refrigerant are removed by the filter 19 and the desiccant 20 that constitute the removing means while flowing down, the water is passed through the outlet 40 to the inlet provided in the connection block 31. Sent in. The liquid refrigerant sent to the sending port in this way is supercooled while passing through the sub heat transfer tubes 33, 33 forming the sub condenser 25. Then, the liquid refrigerant supercooled in this way is sent toward the evaporator 5 through the outlet port formed in the outlet block 37.

When it is necessary to repair or replace the liquid tank 24, the retaining belt 44 is removed and the bolts 38, 38 are removed, so that the mounting block provided at the lower end of the liquid tank 24. 36
Is removed from the connection block 31 fixed to the lower outer surface of the one header 26a. As a result, capacitor 2
It is possible to repair or replace only the liquid tank 24 while leaving 3 and the sub condenser 25 as they are.

Particularly, in the case of the capacitor provided with the liquid tank of the present invention, the connection block 31 is used as described above.
The liquid tank 24 is offset to the front side as compared with the one header pipe 26a by making the shape of the above asymmetrical. Therefore, the rear portion of the liquid tank 24 having a diameter larger than that of the header pipe 26a is connected to the condenser 2
3 and the sub-capacitor 25 do not project more rearward than the rear rear surface. Condenser 23 and sub-condenser 25 constituting a vapor compression refrigerator for an automobile air conditioner
Is a radiator 4 for radiating cooling water as shown in FIG.
Immediately before 8 is often placed close to the front surface of the radiator 48. Therefore, if the rear portion of the liquid tank 24 projects rearward from the rear surface of the condenser 23 and the sub-condenser 25, it becomes difficult to dispose the condenser including the liquid tank 24 immediately in front of the radiator. On the other hand, in the case of the condenser equipped with the liquid tank of the present invention, the rear portion of the liquid tank 24 does not project rearward from the rear rear surface of the condenser 23 and the sub-condenser 25. It becomes easy to arrange it just before the radiator 48. In other words, the automobile design becomes easier.

Next, FIG. 6 shows a second embodiment of the present invention. In the case of the present embodiment, by supporting and fixing the case 35 that constitutes the liquid tank 24 in front of the header pipe 26a that constitutes the condenser 23, the central axis of the case 35 is set to the front side with respect to the central axis of the header pipe 26a ( Figure 6
Located on the lower side). Therefore, in the case of the present embodiment, the case 35 does not easily interfere with the radiator 48, and the case 35 does not project to the side of the capacitor 23. In this embodiment having such a structure, the header pipe 26a and the side panel 4 of the automobile body are used.
When 9 and 9 are close to each other, it is possible to prevent interference between the liquid tank 24 and the side panel 49. Therefore, the structure of this embodiment is effective when a condenser equipped with a liquid tank is installed in an engine room having a small width. If the width of the engine room is the same, the width of the core portion of the capacitor 23 installed in the engine room can be increased. As the liquid tank 24 used in such a structure of the second embodiment, the same liquid tank as that of the first embodiment described above can be used. That is, in this embodiment, only the shape of the connection block 31a fixed to the header pipe 26a is changed, and the same liquid tank 24 as that of the first embodiment can be used.

The effect of offsetting the liquid tank 24 to the front side as compared with the header pipe 26a is that the liquid tank 24 is not necessarily of the removable type (the fixed type structure as shown in FIG. 8). But you can get it.
Further, a structure having no sub-capacitor (as also shown in FIG. 8) can be similarly obtained. The fixed structure of these liquid tanks and the structure without a sub-capacitor are also subject to the present invention.

[0028]

Since the condenser provided with the liquid tank of the present invention is constructed and operates as described above, the condenser and the liquid tank can be integrally handled as in the conventional structure, and therefore, the limit inside the engine room is limited. Since it is easy to install in the space provided and it is not necessary to separately secure the vibration resistance of the condenser and the liquid tank, the installation work can be facilitated. While maintaining the above effect as it is, the condenser and the radiator can be arranged close to each other, so that the condenser can be installed in a limited space and the automobile design can be facilitated. Even if the positional relationship between the liquid tank and the condenser is changed, the same body can be used as the condenser body and the liquid tank. Therefore, the same component can be used for different vehicle types, which contributes to cost reduction by simplifying manufacturing work and component management. It has an excellent effect.
