2. Description of the Related Art Some condensers used in a refrigerating cycle of an air conditioner for a vehicle include, for example, one of a pair of header pipes as shown in Japanese Patent Application Laid-Open No. 4-131667. A liquid receiving part for storing a liquid-phase refrigerant condensed and liquefied by cooling is provided in addition to provide a function as a liquid tank, and a desiccant is arranged in a form that partitions the inside of the liquid receiving part into upper and lower parts. Liquid phase refrigerant flowing down through the desiccant to absorb moisture,
As disclosed in Japanese Patent Application Laid-Open No. 4-43271, there is known a method in which a pack-type desiccant is rolled into a cylindrical shape and inserted into a liquid receiving portion provided alongside a header pipe.

In the former former structure, since the refrigerant passage area of the desiccant is small, the flowability of the liquid-phase refrigerant deteriorates, leading to a decrease in the cooling performance.

In order to increase the refrigerant passage area of the desiccant, the diameter of the header pipe may be increased. However, since the condenser is disposed on the front side of the engine room at the front of the vehicle body, the dimension in the vehicle width direction is reduced. Therefore, when the diameter of the header pipe is increased, the width of the cooling core between the pair of header pipes is reduced, and the cooling efficiency of the condenser is reduced. In this case, too, the cooling performance is reduced.

Further, in the latter structure, since the water content of the liquid-phase refrigerant passing through the central portion of the cylindrically-shaped packed desiccant cannot be absorbed, the residual water in the refrigeration cycle cannot be completely removed. This leads to a decrease in cooling performance.

Accordingly, the present invention can increase the refrigerant passage area of the desiccant without increasing the diameter of the header pipe, improve the flowability of the liquid-phase refrigerant, and dry all of the liquid-phase refrigerant. An object of the present invention is to provide a condenser capable of improving the performance of removing moisture by passing the same through an agent.

According to a first aspect of the present invention, there is provided a digital camera comprising:
In a condenser, a plurality of cooling pipes are connected in a multi-stage manner in a vertical direction across a pair of header pipes, and a liquid receiving part for storing a liquid-phase refrigerant condensed and liquefied by cooling is provided in one of the header pipes. A partition plate is provided on the lower side of the liquid receiving portion to partition the inside of the liquid receiving portion into upper and lower two chambers, and a desiccant is passed through the upper end cover and the partition plate into the liquid receiving portion. A filled tubular desiccant container having excellent liquid permeability is detachably suspended, and a refrigerant passage for introducing a liquid-phase refrigerant from one header pipe is provided on an upper portion of the liquid receiving portion.

According to the structure of the first aspect, the liquid-phase refrigerant flowing from one header pipe through the refrigerant passage into the liquid receiving portion falls into the upper chamber separated by the partition plate without resistance. After flowing into the desiccant container on the way down, or falling to the partition plate, and then flowing into the desiccant container, the liquid phase refrigerant passes through the desiccant layer to remove moisture, and then the desiccant is removed. It flows out from the lower part of the container to the lower chamber below the partition plate and is stored.

[0009] As described above, the liquid-phase refrigerant flowing from the header pipe into the liquid receiving portion entirely flows into the desiccant container in the upper chamber, passes through the desiccant layer, and flows out and is stored in the lower chamber. Removal performance can be improved.

In addition, since the liquid-phase refrigerant drops from the header pipe to the upper chamber of the liquid receiving portion without resistance, and flows from the upper chamber into a cylindrical desiccant container having a large surface area, the flow resistance is low. It is suppressed and the flowability of the liquid phase refrigerant is improved,
Cooling performance can be improved.

According to the configuration of the second aspect, the desiccant container is directly attached by screwing the screw portion of the head portion into the screw hole of the end cover on the upper side of the liquid receiving portion. In addition, the serviceability is good, and a dedicated part for mounting can be eliminated, which is advantageous in cost.

The liquid refrigerant flowing into the container body 13 flows through the layer of the desiccant 11 and reaches the lower portion of the container body 13 below the partition plate 8, and flows through the layer of the desiccant 11. During the process, the water is removed, flows out into the lower chamber 7B through the small holes 14 in the lower peripheral wall of the container body 13 and is stored, and the liquid-phase refrigerant stored in the lower chamber 7B is the lower refrigerant. Passage 12B
Flows into the lower refrigerant inflow chamber 30a, passes through the lower subcool pipe 5a to the refrigerant outlet 23 of the header pipe 2, is cooled again by the subcool pipe 5a, and is led out from the refrigerant outlet 23 to an indoor air conditioning unit (not shown). Is done.

According to the first aspect, all of the liquid-phase refrigerant flowing from one header pipe into the liquid receiving section flows into the desiccant container in the upper chamber, and flows into the lower chamber after passing through the desiccant layer. Since it is stored, the performance of removing water can be enhanced.

Further, since the liquid-phase refrigerant drops from the header pipe into the upper chamber of the liquid receiving portion without resistance, and flows from the upper chamber through a cylindrical desiccant container having a large surface area, the flow resistance is small. It is suppressed and the flowability of the liquid phase refrigerant is improved,
Cooling performance can be enhanced in combination with the above-described ability to remove moisture.

According to the second aspect, the desiccant container is directly attached by screwing the screw portion of the head portion into the screw hole of the end cover on the upper side of the liquid receiving portion. The work is easy, the serviceability can be improved, and a dedicated part for mounting can be eliminated, so that the cost can be reduced.
