To prevent a failure caused by expansion of a heating medium even in the case that a reservoir is provided only in one circuit of two circuits connected in parallel with each other.SOLUTION: A thermal management circuit 100 comprises: a low-temperature circuit 130 including a reservoir tank 136 and a battery circuit 170 including no reservoir tank. A heat management system 1 includes an ECU configured to switch a plurality of modes related to a flow path of a heat medium in the heat management circuit 100 by controlling a five-way valve 180. The plurality of modes includes a first mode (first circuit mode) and a second mode (third circuit mode). The first mode is a mode in which the low-temperature circuit 130 and the battery circuit 170 are connected in series. The second mode is a mode in which the low-temperature circuit 130 and the battery circuit 170 are connected in parallel, and a part of the heat medium flowing through the battery circuit 170 flows to the low-temperature circuit 130 via the five-way valve 180.SELECTED DRAWING: Figure 2

    【課題】互いに並列接続される2つの回路のうちの一方の回路にしかリザーバが設けられていなくても、熱媒体の膨張に伴う不具合を防止する。【解決手段】熱管理回路100は、リザーバタンク136を含む低温回路130と、リザーバタンクを含まないバッテリ回路170とを有する。熱管理システム1は、五方弁180を制御することによって、熱管理回路100における熱媒体の流通経路に係る複数のモードを切り替えるECUとを備える。複数のモードは、第1モード(第1回路モード)および第2モード(第3回路モード)を含む。第1モードは、低温回路130とバッテリ回路170とが直列接続されるモードである。第2モードは、低温回路130とバッテリ回路170とが並列接続され、かつバッテリ回路170を流通する前記熱媒体のうちの一部が五方弁180を介して低温回路130に流通するモードである。【選択図】図2
