Title:
AIR CONDITIONING DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2016/151878
Kind Code:
A1
Abstract:
The present invention is provided with: an evaporator (6) wherein a compressed refrigerant is vaporized; an expansion valve that expands the refrigerant before the refrigerant flows into the evaporator (6); refrigerant pipes (26, 27) that connect the evaporator (6) and the expansion valve to each other; and a unit case (3), which houses the evaporator (6), the expansion valve, and the refrigerant pipes (26, 27), and which has an air flow channel (4) for passing air through the evaporator (6). In the unit case (3), a refrigerant pipe housing chamber (31) for housing the refrigerant pipes (26, 27) is partitioned by being isolated from the housing section for the evaporator (6) and the air flow channel (4). The outer circumferential surfaces of the refrigerant pipes (26, 27) are separated from the inner wall surfaces of the refrigerant pipe housing chamber (31). Furthermore, the thickness (t1) of the wall surfaces of the refrigerant pipe housing chamber (31) is larger than the thickness (t2) of the wall surfaces of the unit case (3).
