Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subcooled condenser (subcooled condenser), and more particularly to a subcooled condenser in which the function of a conventional receiver dryer containing a desiccant is provided to the condenser itself.

[0002]

2. Description of the Related Art Heretofore, there has been known a subcooled type condenser in which a refrigerant condensing core for condensing a refrigerant and a subcooling core for further supercooling the refrigerant condensed by the refrigerant condensing core are formed into one condenser as a whole. ing.
In conventional subcooled condensers, the liquid reservoir for the refrigerant and the components for removing moisture in the refrigerant circuit incorporating the condenser are provided separately from the subcooled condenser or brazed to form an integral part. To provide additional connection to the capacitor, or to provide a structure in which the inside of the header is partitioned by a vertical cross section.

[0003] For example, Japanese Patent Application Laid-Open No. Hei 8-219590 discloses that refrigerant flowing into the inside of a condenser main body in which a plurality of flat tubes for condensation and supercooling are arranged in parallel is separated into gas and liquid. FIG. 1 shows a structure in which a liquid receiver containing a dryer inside is joined. Also, Japanese Patent Application Laid-Open No. 9-5
Japanese Patent No. 3867 discloses a structure in which a liquid receiving section in which a desiccant container is suspended from a header pipe of a condenser through an end plate cover and a partition plate is provided. Further, Japanese Patent Application Laid-Open No. 9-170853
JP-A-9-170854 discloses a structure in which a separate liquid tank is provided on a side surface of a header pipe in an integrated main body capacitor and a sub-condenser, and is disclosed in JP-A-10-122705. Discloses a structure in which a liquid tank is provided on a side surface of one header pipe constituting a capacitor.

In Japanese Patent Application Laid-Open Nos. 9-48232 and 3-241273, only a liquid storage function is provided in a header tank portion of a capacitor, and a dryer is separately installed in a refrigerant circuit for a water removing function. The structure is disclosed.

[0005]

However, Japanese Unexamined Patent Publication Nos. Hei 8-219590, Hei 9-53867, Hei 9-170853, Hei 9-170854 and Hei 10-122705 disclose the above. In the structure, the liquid receiving part with moisture removal function is joined or provided separately on the side of the header pipe of the integrated main body condenser and sub-condenser. When placing capacitors,
Since the area occupied by the liquid receiving part is reduced by the area of the condenser heat radiation part, there is a problem that the heat radiation performance of the capacitor is reduced.

Further, as in the structures disclosed in JP-A-9-48232 and JP-A-3-241273, a structure is provided in which a water removing function component is separately installed in a refrigerant circuit.
If the function of the liquid receiving part provided to the header tank part of the condenser is limited to liquid storage, the condenser itself does not need to have a dryer replaceable structure by omitting the water removal function. Although the structure can be simplified as compared with the case where a liquid receiving part having a removing function is provided,
Since the dryer is separately installed, when it is used for an air conditioner for a vehicle, there is a disadvantage that the layout of an engine room or the like is deteriorated and the cost is increased due to the separate installation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a subcooled capacitor having both a liquid storing function and a water removing function, while preventing a reduction in the area of the heat radiating portion of the capacitor and maintaining a predetermined heat radiating performance. It is in.

Another object of the present invention is to reduce the number of parts in the refrigerant circuit as a whole and to reduce the size of the system as a whole by providing the subcool type condenser itself with a moisture removing function as compared with a case where a separate dryer is provided. It is to measure.

It is another object of the present invention to easily incorporate a desiccant therein.

Means for Solving the Problems In order to solve the above problems, a subcooled type capacitor according to the present invention is a capacitor which is connected by a plurality of heat exchange tubes extending in parallel between two headers. A first header that is divided into a refrigerant condensing core that condenses the refrigerant and a subcool core that further supercools the refrigerant condensed by the refrigerant condensing core, and is located on the inlet side of the subcool core among the two headers. A subcool-type condenser in which at least a header portion corresponding to an inlet portion to the subcool core is formed as a refrigerant reservoir, wherein at least one of the headers contains a desiccant. .

In the above subcool type capacitor, the desiccant may be filled in a liquid-permeable container and housed in the header, and the granular desiccant may be adhered with a binder or the like.
Instead of using a special container member, the desiccant itself formed into an integrally solidified mass may be stored in the header. Further, the desiccant formed into an integral mass may be housed in a container, which may be housed in a header.

The cross-sectional shape of the desiccant container can be, for example, substantially circular, approximately semicircular, substantially oblong, or the like. When the cross section of the container is formed in a substantially elliptical shape, the cross section of the header is preferably formed in a substantially oval shape.

The desiccant container has, for example, a skeleton. In particular, it is preferable that the container has a skeleton and a liquid-permeable mesh portion. This mesh portion preferably has the function of a strainer. In such a container, at least one of the skeleton and the mesh portion can be formed of a resin. Alternatively, at least one of the skeleton and the mesh portion may be formed of metal.

Further, the desiccant container may be configured to have a skeleton and a punching member. The punching member can be formed by punching metal.

Since the connection between the header and the heat exchange tube is usually performed with the tip of the heat exchange tube slightly protruding into the header, the tip of the heat exchange tube protruding into the header is connected to a desiccant or drying agent. In order to avoid interference with a container filled with the agent, a gap is preferably formed between the two.

For example, the tips of the plurality of heat exchange tubes are cut out along the outer peripheral surface of the desiccant or desiccant container, so that the desiccant or desiccant container and the tips of the plurality of heat exchange tubes can be connected. By adopting a structure in which a gap is formed therebetween, interference between the desiccant or the desiccant container and the tip of the heat exchange tube is avoided.

The desiccant or desiccant container can be intermittently contained in the header. However, from the viewpoint of easy handling or drying performance, the desiccant or desiccant container extends over substantially the entire length of the header. Is preferred.

Further, in this subcooled condenser, a partition plate is provided at a position corresponding to a boundary between the refrigerant condensing core and the subcool core in at least one of the headers, and the desiccant passes through the partition plate. And it is preferably supported by a partition plate. When the desiccant is filled in the container, the container may be supported by the partition plate. By the support by the partition plate, the desiccant or desiccant container is fixed at a desired position or posture in the header.

In this structure, the through hole of the desiccant or desiccant container of the partition plate has the same shape as the cross-sectional shape of the desiccant or desiccant container, and is formed in a hole which is equal to or slightly larger than that. Thus, the desiccant or the desiccant container can be easily inserted and removed, and the desiccant or the desiccant container can be maintained in a predetermined posture after penetration.

The desiccant may be filled in a bag and stored in the header. Further, a desiccant may be filled in the bag and stored in the container.

Further, the desiccant may be formed, for example, as one integral mass. Further, the desiccant may be fixed by a heat-shrinkable tube.

In such a subcooled type capacitor according to the present invention, it is possible to integrally braze the whole while the desiccant is contained in the header as described above. For example, the desiccant container and the header can be integrally brazed.

In the above-described subcooled condenser according to the present invention, the refrigerant from the outlet of the refrigerant condensing core flows in the first header toward the inlet of the subcooled core and is formed in the liquid reservoir. Then, it flows into the subcool core via the header portion corresponding to the entrance of the subcool core. Since the desiccant is stored in one of the headers, moisture is removed from the refrigerant flowing through the condenser by the desiccant. In particular, by storing the desiccant in the first header, the refrigerant from the outlet of the refrigerant condensing core flows to the inlet of the subcool core through the desiccant filling part. Moisture is properly removed. That is, in the first header,
A portion having a liquid storage function and a portion having a water removing function will be configured together, and these portions do not cause a problem that the header becomes particularly large or the flow of the refrigerant is obstructed. , The first header. Therefore, the area of the heat radiating portion as the entire subcooled capacitor is not reduced, and the desired heat radiating performance is maintained.

Further, by providing both the liquid storage function and the water removal function to the subcooled type condenser, the number of parts in the entire refrigerant circuit can be reduced and the size of the entire system can be reduced as compared with a case where a separate receiver dryer or the like is provided. Achieved.

Further, by providing the partition plate as described above, the desiccant or desiccant container is held at a desired position in the header in a desired posture. Further, by forming a gap between the desiccant or the desiccant container and the tip of the heat exchange tube, it is possible to easily avoid the problem of interference between them.

From the entire length, it extends from the inside of the first header 3 to the entire length of the header portion 3 a corresponding to the entrance to the subcool core 10, and the desiccant 13 is also accommodated substantially over the entire internal length of the first header 3. . Reference numeral 17 in FIG. 2 denotes a liquid refrigerant stored in the liquid storage section 11 in the first header 3.

In this embodiment, the desiccant container 14 is
In the first header 3, the desiccant container 14 is disposed at a position slightly eccentric to a position opposite to the tip of the heat exchange tube 4, and has a substantially circular cross section. An appropriate gap 18 is formed between the tip of each heat exchange tube 4 protruding into the first header 3 and the desiccant container 14 having a substantially circular cross section. Interference between the refrigerant and the desiccant container 14 is avoided, and the fluidity of the refrigerant in the first header 3 and the ease with which the refrigerant enters and exits the desiccant container 14 and the desiccant 13 filled therein. Is secured.

At the position corresponding to the boundary between the refrigerant condensing core 9 and the subcool core 10 in the first header 3, as shown in FIG. 3, a partition plate 19 is provided. Is inserted through a hole 20 formed in the partition plate 19 and extends through the partition plate 19. The hole 20 formed in the partition plate 19 is formed in a substantially circular hole similarly to the cross-sectional shape of the desiccant container 14. The size of the hole 20 is shown in FIG.
As shown in the figure, the cross-sectional area of the desiccant container 14 is substantially the same,
Alternatively, the desiccant container 14 is preferably slightly larger than that, so that the desiccant container 14 can be inserted while being guided by the hole 17. In order to determine the insertion position at a predetermined position, it is preferable that an engagement plate 21 to be locked to the partition plate 19 is added to the container 14.

Alternatively, as shown in FIG. 4, the desiccant container portion inserted into the hole 20 has a stepped portion such that the cross section of the desiccant container portion on the lower side (subcool core side) becomes larger. Formed in a desiccant container 14a having a shape,
The step portion 22 may be locked by the partition plate 19, and an engagement plate similar to that shown in FIG. 3 may be added. In any case, it is preferable that the tip-side insertion portion (the upper end portion in the illustrated example) of the desiccant container 14 be tapered so as to be easily inserted into the hole 20 of the partition plate 19. When the desiccant container 14 is inserted into the hole 20 of the partition plate 19, the desiccant container 14 is held at a predetermined position and a predetermined posture by the partition plate 19 at that portion.

In this embodiment, as shown in FIGS. 2 and 5, the lid 23 on the subcool core side of the first header 3 is configured as a detachable lid, and the desiccant container 14 is placed inside the header 3. The lid 23 can be closed after it has been inserted. Alternatively, the desiccant container 14
After the desiccant container 14 is inserted into the header 3, the desiccant container 1 is fixed together with the lid 23.
4 may be fixed. In the latter case, the lid 23 can be attached to and detached from the first header 3 together with the desiccant container 14, and replacement of the desiccant container 14 becomes easier.

The partition plate 1 in the first header 3 described above.
9 functions as a guide member at the time of insertion and a holding member after insertion into the desiccant container 14, so that a plurality of 9 can be provided in the longitudinal direction of the first header 3 as necessary.

In the subcooled type capacitor 1 according to the first embodiment having the above-described structure, a liquid reservoir 11 having a liquid storage function is formed in the lower portion of the first header 3 so as to be separately received. It is not necessary to provide a liquid container or the like, and a water-permeable desiccant container 14 filled with a desiccant 13 is inserted and extended from the refrigerant condensing core 9 to the inlet of the subcool core 10 so that the water removing function is improved. This eliminates the need to provide a separate dryer. Since the liquid reservoir 11 and the desiccant container 14 are formed and installed compactly in the first header 3, the area of the heat radiating portion as the subcooled capacitor 1 is not reduced.
That is, the function of the liquid receiver and the function of the dryer can be given to the subcool type capacitor 1 itself while maintaining the heat radiation performance of the subcool type capacitor 1. Therefore, it is possible to greatly reduce the number of components in the entire refrigerant circuit using the subcool type capacitor 1, and to significantly reduce the size of the entire system. Further, for example, it is also possible to braze the desiccant container 14 integrally with the first header 3 in a state in which the desiccant 13 is stored, and this brazing is performed, for example, in the entire brazing process (for example, heating (A brazing step in a furnace), it is possible to facilitate the manufacture of the subcool type capacitor 1 having a desirable form.

When the desiccant container 14 is supported by the partition plate 19, the desiccant container 14 can be held at a desired position and posture in the first header 3. Also,
If the desiccant container 14 is fixed and supported by both the lid 23 and the partition plate 19, the desiccant container 14 is more reliably held at the desired position and posture.

Further, by providing an appropriate gap 18 between the desiccant container 14 having a substantially circular cross section and the tip of the heat exchange tube 4, the inserted desiccant container 14 and the tip of the heat exchange tube 4 The interference is reliably avoided, and the occurrence of a defect due to the interference is prevented.

The above interference can be avoided by another structure. 6 to 8 show a subcooled type capacitor 31 according to a second embodiment of the present invention. In the present embodiment, the desiccant container 32 having a substantially circular cross section is disposed substantially at the center in the cross section of the header 3, and is held by the partition plate 33 at a position halfway in the longitudinal direction. Then, the desiccant container 32 and the heat exchange tube 3
In order to avoid interference with the tip of
4 is cut out in an arc shape along the outer peripheral surface of the desiccant container 32. However, if the interference can be avoided even without the cutout, there is no need to separately cut out. Since other configurations, operations, and effects are the same as those of the first embodiment, the same reference numerals as those shown in FIGS.

FIGS. 9 and 10 show a subcooled capacitor 41 according to a third embodiment of the present invention. In the present embodiment, the desiccant 42 is formed as one integral mass, and the desiccant container is not used. However, the lump formed may be stored in the above-described container. For example, a method of solidifying the particulate desiccant using an adhesive or a method of solidifying the particulate desiccant by heat fusion can be adopted for the formation into such a mass.

In such a configuration, by forming the desiccant 42 as one integral mass, the desiccant container can be omitted, and the structure can be further simplified.

Further, although not shown, the desiccant can be fixed by a heat-shrinkable tube or held in a desired shape. The heat-shrinkable tube may be made water-permeable by making a large number of holes. Furthermore, it is also possible to store in a header without a container in a state of being fixed with a heat-shrinkable tube, or to store the entire heat-shrinkable tube in a container and store it in the header.

[0044]

As described above, according to the subcooled capacitor of the present invention, the liquid reservoir is formed in the header, and the desiccant is filled in the container or solidified into an integral mass. By storing and holding it in a predetermined position inside, the subcool type condenser itself has a liquid storage function of the refrigerant without attaching special extra parts, and without increasing the size of the capacitor or reducing the area of the heat radiation part. And water removal capability. Therefore, it is possible to reduce the size and the cost of the refrigerant circuit and the entire system using the subcool type capacitor while securing the desired performance as the subcool type capacitor.
