摘要

A cooler unit housing (12) is located in a passenger room (PR) near a dashboard (100) of a motor vehicle. A piping arrangement of the cooler unit comprises a pipe joint which is positioned at and supported by an opening (112) of the dashboard. The pipe joint has a first face (22) facing toward the passenger room (PR) and a second face (24) facing toward the engine room (ER). An expansion valve unit (20) is connected to the first face (22) of the pipe joint. Coolant inlet and output pipes are arranged, each having one end connected to an evaporator (14) in the cooler unit housing (12) and the other end led to the expansion valve unit (20). A grommet (30) is disposed between a peripheral portion of the opening (112) and an outer wall portion of the pipe joint thereby to establish sealing therebetween. <IMAGE>
