Air-conditioning system for vehicles

摘要

According to the present invention, a blower/evaporator housing case for housing side-by-side a blower that is rotated by a motor and creates an air flow and an evaporator linked with coolant pipings through which a coolant flows in and out is provided so as to completely prevent leakage of condensed water which collects at the evaporator of the an air-conditioning system for automotive use and also to simplify the structure of a means for locking used to lock an expansion valve at the evaporator. The blower/evaporator housing case is constituted of two recessed members, i.e., an upper recessed member and a lower recessed member, set on the two sides of a parting line extending along the horizontal direction. The means for locking used to lock the expansion valve is formed at joint portions at the edges of the upper and lower recessed members constituting the blower/evaporator housing case.
