To appropriately configure a heat management system in a vehicle by an on-vehicle inverter unit for performing drive control of a rotary electric machine and a vehicle drive system as main components and to configure the on-vehicle inverter unit and the vehicle drive system in small size.SOLUTION: A refrigerant module 1 constituting a refrigerant circuit for circulating refrigerant for an on-vehicle air conditioner comprises: a refrigerant channel 29; and a plurality of functional components 31, 32, 41, and V. The refrigerant channel 29 is formed inside a cover 93 which blocks an opening 9a of a case 9 for accommodating an inverter module INV. The cover 93 comprises a projection 93p projecting on any side in a direction along the opening 9a to the case 9. The specific functional components 31, 32, 41 as at least a part of the plurality of functional components 31, 32, 41, and V are attached to a surface 93b facing a case side X2 in an opening direction at the projection 93p and connected with the refrigerant channel 29.SELECTED DRAWING: Figure 1
【課題】回転電機を駆動制御するための車載インバータユニットや車両用駆動装置を中核として車両における熱マネジメントシステムを適切に構成すると共に、車載インバータユニットや車両用駆動装置を小型に構成する。【解決手段】車載エアコンディショナ用の冷媒を循環させる冷媒回路を構成する冷媒モジュール1は、冷媒流路29と、複数の機能部品31,32,41,Vとを備える。冷媒流路29は、インバータモジュールINVを収容するケース9の開口部9aを閉塞するカバー93の内部に形成される。カバー93は、ケース9に対して開口面9aに沿う方向の何れかの側に突出した突出部93pを備える。複数の機能部品31,32,41,Vの少なくとも一部である特定機能部品31,32,41は、突出部93pにおける開口方向ケース側X2を向く面93bに取り付けられ、冷媒流路29に接続されている。【選択図】図1
