PROBLEM TO BE SOLVED: To prevent increase in work hours of the assembly of a rear cooler and cost increase that are caused by applying multiple heat insulation packings.SOLUTION: A rear cooler includes: an evaporator 32 which cools air; an expansion valve 33 which decompresses a refrigerant supplied to the evaporator 32; a case 30 which stores the evaporator 32 and the expansion valve 33, the case 30 having a drain discharge part 30d which drains drain water occurring in the evaporator 32 and the expansion valve 33 to the exterior; and an insulator 31 which is placed continuing from a bottom part of the case 30 that is located below the expansion valve 33 to an area located below the evaporator 32 and guides the drain water to a drain discharge part 30d.
【課題】、複数の断熱パッキンを貼付することによるリアクーラの組立て作業の工数増加及びコスト増加を防止する。【解決手段】空気の冷却を行うエバポレータ32と、エバポレータ32に供給される冷媒を減圧する膨張弁33と、エバポレータ32及び膨張弁33を収容すると共にエバポレータ32及び膨張弁33で生じたドレン水を外部に排出するドレン排出部30dを有するケース30と、ケース30の底部であって膨張弁33の下方からエバポレータ32の下方に連続して載置され、ドレン水をドレン排出部30dに案内するインシュレータ31とを備える。【選択図】図2
