To provide a temperature control system for vehicle capable of suppressing a second temperature control medium from flowing back from a first branch flow passage to a second branch flow passage.SOLUTION: A temperature control system 10 for vehicle comprises: a first temperature control circuit 61 where a first temperature control medium TCM1 circulates; a second temperature control circuit 62 where a second temperature control medium TCM2 circulates; and a heat exchanger 63 which exchanges heat between the first temperature control medium TCM1 and the second temperature control medium TCM2. The second temperature control circuit 62 has a pressure feed flow passage 620a which has one end part connected to the branch part 624 and the other end part connected to a confluence part 625, and a first branch flow passage 620b1 and a second branch flow passage 620b2. At a confluence part 625, a backflow suppression part 625a is formed which suppresses the second temperature control medium TCM2 from flowing back from the first branch flow passage 620b1 to the second branch flow passage 620b2.SELECTED DRAWING: Figure 3 【課題】第１分岐流路から第２分岐流路へ第２温調媒体が逆流するのを抑制することができる車両用温調システムを提供する。【解決手段】車両用温調システム１０は、第１温調媒体ＴＣＭ１が循環する第１温調回路６１と、第２温調媒体ＴＣＭ２が循環する第２温調回路６２と、第１温調媒体ＴＣＭ１と第２温調媒体ＴＣＭ２との間で熱交換を行う熱交換器６３と、を備える。第２温調回路６２は、一端部が分岐部６２４に接続し他端部が合流部６２５に接続する圧送流路６２０ａ、第１分岐流路６２０ｂ１及び第２分岐流路６２０ｂ２を有する。合流部６２５には、第１分岐流路６２０ｂ１から第２分岐流路６２０ｂ２へ第２温調媒体ＴＣＭ２が逆流するのを抑制する逆流抑制部６２５ａが形成されている。【選択図】図３
