To provide a vehicular heat management system capable of effectively using exhaust heat from on-vehicle equipment which causes heat generation during operation.SOLUTION: A vehicular heat management system comprises: a heat pump cycle 2 for heating blown air blown into a vehicle cabin; and a refrigerant circulation circuit 3 for exhaust heat which releases exhaust heat from on-vehicle equipment 50-53 to outside air. An exhaust heat recovery heat exchange part 61a for performing heat exchange in the heat pump cycle 2 between a refrigerant for the cycle and heated air heated by the exhaust heat from the on-vehicle equipment 50-53 and a discharge heat exchange part 61c for performing heat exchange in the refrigerant circulation circuit 3 for the exhaust heat between a refrigerant for the exhaust heat and the heated air are integrally configured as a combined type heat exchanger 61 capable of transferring heat between the refrigerant for the cycle and the refrigerant for the exhaust heat. In addition, the on-vehicle equipment 50-53 and at least a part of the combined type heat exchanger 61 are accommodated in a heat insulation housing 4. Thus, the exhaust heat from the on-vehicle equipment 50-53 is used for heating the blown air via the heated air.SELECTED DRAWING: Figure 1
【課題】作動時に発熱を伴う車載機器の排熱を有効に利用可能な車両用熱管理システムを提供する。【解決手段】車室内に送風される送風空気を加熱するヒートポンプサイクル2と、車載機器50〜53の排熱を外気に放熱させる排熱用冷媒循環回路3とを備え、ヒートポンプサイクル2にてサイクル用冷媒と車載機器50〜53の排熱によって加熱された加熱空気とを熱交換させる排熱回収熱交換部61aおよび排熱用冷媒循環回路3にて排熱用冷媒と加熱空気とを熱交換させる排出熱交換部61cを、サイクル用冷媒と排熱用冷媒との間の熱移動が可能な複合型熱交換器61として一体的に構成する。さらに、車載機器50〜53と複合型熱交換器61の少なくとも一部とを断熱筐体4の内部に収容する。これにより、車載機器50〜53の排熱を、加熱空気を介して、送風空気を加熱するために利用する。【選択図】図1
