分離性が向上する。In the above embodiment, the main body 2a of the condenser 2 is installed parallel to the header pipe 1b of the condenser 1, so if the condenser 1 is installed diagonally due to the installation space of the vehicle, the receiver main body 2a is similarly installed diagonally, and as a result, due to the gas-liquid separability of the liquid receiver main body 2a, the liquid refrigerant that accumulates inside the tank of the liquid receiver main body 2a accumulates obliquely. Therefore, the gas refrigerant is easily sucked into the suction pipe 2d. Therefore, in this embodiment, the upper mounting bracket 1g of the outlet side header pipe 1b is replaced with a mounting bracket 1h having a long groove shaped like an arc with the outlet side union 1f as the center, as shown in FIG. By fixing the mounting bracket 1h to the ear part 2 by inserting the liquid receiver body 2a into the outlet side union 1 with respect to the condenser 1 installed diagonally.
Attach in the vertical direction rotated around f. The lower mounting bracket 1n has a shape having a recess that matches the inclination direction of the header pipe 1b. As a result, in this embodiment, the liquid receiver body always faces in the vertical direction, so that the gas-liquid separation property is improved.
