ヘツド部６が取付けられている。 This liquid tank adjusts the amount of refrigerant circulating in the cooling cycle, removes moisture and dirt contained in the air conditioner, and converts it into a clean refrigerant.
It has the function of a filter for supplying to the expansion valve, and high-pressure refrigerant is usually stored inside. Therefore, this liquid tank must be highly pressure resistant.
As shown in FIGS. 4 and 5, a conventional liquid tank has end plates 2, 2 welded to the ends of a cylindrical body 1, and a container 3.
It has high pressure resistance. Note that this upper end plate 2 has an inlet portion 4 through which a refrigerant inflow pipe is communicated.
A head portion 6 is attached which has an outlet portion 5 with which a refrigerant outlet pipe is communicated.

が困難となる。(Problem that the invention aims to solve) However, in the case of conventional steel liquid tanks, the end plate 2 and the cylindrical body 1, and the end plate 2 and the head part 6 are joined by arc welding A, so it is relatively easy to use. Although joining is possible easily, when aluminum material is used, welding becomes difficult because there is little difference in melting point between the weld metal and the base metal.
しかも、スチールよりも高価なアルミ材を用い
るため材料費も高くなるという問題がある。 Moreover, since aluminum, which is more expensive than steel, is used, there is a problem in that the material cost is also high.

ようにすると材料費がさらに嵩み好ましくない。 Note that Japanese Patent Application Laid-Open No. 150761/1989 discloses a structure in which an end plate and a cylindrical body are connected via a coupling member with low deformation resistance, but this method reduces material costs. is even bulkier, which is undesirable.
また、実開昭53−165365号公報には、レシーバ

ある。 Furthermore, Japanese Patent Publication No. 55-48895 discloses a method for joining two members;
This is similar to Publication No. 150761, in which the two are connected via a connecting member with low deformation resistance, and the actual situation is that the above-mentioned problems have not been solved yet.

Perforated plates 10, 10 provided inside this cylindrical body 1
It has a drying section 12 filled with a desiccant 11 in between. The upper end plate 2 is provided with an introduction hole 13 for guiding the refrigerant into the inside of the cylindrical body 1, and a discharge hole 14 for guiding the refrigerant to the outside of the cylindrical body 1. 15 is attached by press fitting, and the lower end of this conduit 15 hangs down to the vicinity of the lower end plate 2.

ため、各部品の製作も容易になる。 In particular, the end plates 2, 2 in this embodiment are hardened by being heated and then cooled, and have uneven portions 17 formed on their outer peripheral surfaces.
The end plate 2 is joined to the cylindrical body 1 by plastically flowing the flesh of the body 1 into a relatively soft cylindrical shape at room temperature, which has not been subjected to any heat treatment. That is, this bonding is performed by inserting the heat-hardened end plate 2 into the cylindrical body 1 and then applying pressure to the cylindrical body 1 from the outer periphery at room temperature. In this way, not only can the two parts be easily connected without welding work, but also the reliability of this connection is high, and since both parts are made of the same material, each part can be manufactured easily. becomes easier.

部１２を挾持する必要がある。 Furthermore, in order to make this bonded state more reliable, an inwardly projecting bead portion 18 is formed on the cylindrical body 1 in the vicinity of the end plate 2 in an annular shape or in a plurality of protrusions. This bead part 18
may be formed at the same time when the end plates 2, 2 and the cylindrical body 1 are joined together by pressure, or the bead portion 18 may be formed after this pressure joining, but in any case, the bead portion 18 may be formed. It is necessary for the bead portion 18 to sandwich the end plate 2 or the drying portion 12.

上を図る上からは好ましいものといえる。 FIG. 2 shows another embodiment of the present invention. In this embodiment, an elastic sealing material 19 such as an O-ring is provided on the end plate 2, and this sealing material 19 is provided between the cylindrical body and the end plate 2. The elastic sealing material 19 is pressed and bonded so as to be pressed. However, this elastic sealing material 1
9, as shown in FIG.
It is better to form the elastic sealing material 19 in the recessed part 20 and interposing the elastic sealing material 9 in the recessed part 20 and joining it under pressure.
This is preferable from the standpoint of improving the quality of the seal, as it prevents unnecessary deformation.

シール製は大巾に向上することになる。 In this embodiment as well, if the cylindrical main body 1 and the end plate 2 are made of the same aluminum material as in the previous embodiment, they can be connected almost integrally.
This connection also becomes more reliable. In particular, since welding or the like is not used as in conventional methods, manufacturing costs can be reduced, and even if aluminum material, which is more expensive than steel, is used, there is no disadvantage in terms of cost. Moreover, the seal between the end plate 2 and the cylindrical body 1 is greatly improved compared to the previous embodiment.

ができる。(Effects of the invention) As is clear from the above explanation, according to the invention, the cylindrical body and the end plate are made of the same aluminum material, and the end plate is heated and hardened to form uneven portions on the outer peripheral surface. However, since the end plate and the cylindrical body are joined by causing plastic flow inside the cylindrical body in this uneven portion, the conventional welding can be abolished, and simple pressure joining can be performed. Since the cylindrical body and the end plate can be connected, not only can the cost disadvantage caused by using aluminum material be eliminated, but also the connection between both members can be made more reliable.
