る。2. Description of the Related Art A cooling cycle of an air conditioner such as a car air conditioner is provided with a dryer tank (also called a receiver tank) for removing moisture in a refrigerant. This is because if moisture is mixed in the refrigerant, the cooling performance is significantly reduced even in a very small amount. FIG. 6 shows a conventional dryer tank.
As shown in FIG. 5, an assembly (shown in FIG. 5) in which an adsorbent storage container C having a group of small holes is fixed and integrated in a skewered manner with a pipe P on both surfaces inside the tank T is mounted. The refrigerant is introduced into the rear chamber separated by the adsorbent storage container C in the dryer tank T by the pipe P, and the internal granular adsorbent M is removed from the group of small holes on the rear surface of the adsorbent storage container C. This is a mechanism in which the moisture in the refrigerant is removed during that time, sent to the front room, and sent out from the front room to the outside.

Then, the filter paper is covered and a lid is provided, and the process is performed. Finally, the adsorbent M is airtightly packed so as not to absorb moisture in the air.

作上の難点を伴う。However, filling the adsorbent M into the adsorbent storage container C after inserting the pipe P is time consuming due to the obstruction of the pipe P, and is an operation under unstable conditions. In the meantime, there is a manufacturing difficulty that the adsorbent M easily absorbs moisture.

ならず、その作業は大変厄介なものであった。[0005] In the assembly process of mounting to the dryer tank T, the length of the pipe P varies depending on the manufacturer, the model, and the like of the dryer tank T.
You have to select and assemble from dozens of pipes (12 kinds of sizes are used for the length between 130mm and 175mm in the case of car air conditioners) and the work is very difficult. It was troublesome.

低下してしまう難点があった。Further, in delivering the integrated assembly between factories, about 80 solids are collectively sealed in a vinyl bag, stored in a can, and transported. Although the one-piece assembly is arranged and stored in the can in one direction, a large clearance space is still formed around the pipe P. Furthermore, if the storage is performed without being organized, the storage space becomes bulky, so that a large amount cannot be stored at once, and the clearance space is further increased. For this reason, there was a problem that the moisture in the interstitial space was adsorbed by the adsorbent M and the adsorbing ability was greatly reduced.

Is filled with a granular adsorbent 7, and a filter paper 9 is placed thereon.
The container part A is formed by fitting a drop lid 5 having an opening corresponding to the outer diameter of the container part A. The filter papers 8, 9 prevent the particles from being discharged from the small hole groups 4, 6, and adsorb fine powder. As shown in FIG. 2, a refrigerant introduction pipe B shown in FIG. 1B is inserted into the through receiving cylinder 3 of the container part A in a skewered state.

Is covered with filter paper 9 and the drop lid 5 is placed. Then, once the drop lid 5 is attached, the container portion A is airtightly packed with the airtight resin sheet K for packing so that the adsorbent 7 does not absorb moisture in the air without any time. (Figure 7 shows the packing state)

The refrigerant introduction pipe B is prepared, and one of them is selected which matches the dryer-tank 1, and the airtight packing of the container part A is unpacked, and the refrigerant introduction pipe B is inserted in a short time. It is fixed in the dryer tank 1 to complete the assembly.

になった。According to the present invention, since the container section A and the refrigerant introduction pipe B are independently assembled as described above, the adsorbent storage container C and the pipe P can be compared with a conventional integrated assembly. Since only the container portion A can be separately manufactured, the automation of the manufacturing is facilitated. Further, in the assembly with the dryer tank 1, the drying tank 1 is used.
The container A can be inserted in advance, and the length of the refrigerant introduction pipe B can be selected and chasingly inserted.

で輸送コストが削減できる。In the delivery of the assembly between factories, the conventional integrated type is bulky due to the protruding portion formed by the pipe, and for example, can store only about 80 solids in one can. In the present invention, the refrigerant introduction pipe B may be separately conveyed without being packed. Therefore, if only the container part A is stored in the same one can, it is possible to store about 150 times or more. As described above, since many can be efficiently transported at a time, transport costs can be reduced.

この結果、吸着材７の湿気吸着量が従来のパイプ一体型

吸着能力を高く保持することが可能となる。In the assembly packaging, the conventional integrated type has a protruding portion formed by a pipe, so that a large interstitial space containing moisture is generated in the airtight packaging, and the moisture there is adsorbed by the adsorbent M. In contrast to this, the moisture adsorption capacity is greatly reduced, but in the present invention, since only the container portion A is airtightly packed, there is almost no gap in which moisture exists.
As a result, the amount of moisture adsorbed by the adsorbent 7 can be reduced by about 70% in the humidity absorption rate as compared with the conventional pipe integrated type, and the moisture adsorption capacity can be kept high.
