るものである。As described above, according to the first aspect of the present invention, the block-shaped capacitor-side joint provided on the capacitor side and the receiver-tank-side joint provided on the corresponding receiver tank side are detachable. And the receiver tank is integrally connected to the condenser, so that the receiver tank can be removed, the maintenance property such as replacement of the desiccant can be improved, and the serviceability is impaired. In addition, the apparatus can be easily assembled by integrating the receiver tank. Since a pipe connecting the condenser and the receiver tank is not required, it is possible to eliminate the external pipe which has been a problem in the past, and to reduce the number of parts and reduce the weight of the entire apparatus. According to the second aspect of the present invention, at least a part of the receiver tank body is inserted into the recess provided in the header pipe, so that the amount of protrusion from the condenser of the receiver tank is reduced, and the entire apparatus can be downsized. It is.
