PROBLEM TO BE SOLVED: To reduce pressure loss caused by equipment.SOLUTION: A vehicle thermal management device comprises: a first heat medium circuit 11 which has a first heat medium passage where a heat medium is circulated; a second heat medium circuit 12 which has a second heat medium passage where the heat medium is circulated; a switching section 40 which switches between a separate mode where the heat medium is circulated separately through the first heat medium circuit 11 and the second heat medium circuit 12 and a coordination mode where the heat medium is circulated straight through the first heat medium circuit 11 and the second heat medium circuit 12; a communication section 43 which is arranged parallel to the switching section 40 in a circulation flow of the heat medium and communicates the first heat medium circuit 11 with the second heat medium circuit 12; and equipment 44 arranged on the communication section 43. A passage cross section of the communication section 43 is smaller than: the passage cross section of a portion of the first heat medium passage to which the communication section 43 is connected; and the passage cross section of the portion of the second heat medium passage to which the communication section 43 is connected.SELECTED DRAWING: Figure 1

    【課題】機器によって生じる圧力損失を低減する。【解決手段】熱媒体が循環する第1熱媒体流路を有する第1熱媒体回路11と、熱媒体が循環する第2熱媒体流路を有する第2熱媒体回路12と、第1熱媒体回路11および第2熱媒体回路12で熱媒体が互いに独立して循環する独立モードと、第1熱媒体回路11と第2熱媒体回路12との間で熱媒体が循環する連携モードとを切り替える切替部40と、熱媒体の流れにおいて切替部40と並列に配置され、第1熱媒体回路11および第2熱媒体回路12とを連通させる連通部43と、連通部43に配置された機器44とを備え、連通部43の流路断面積は、第1熱媒体流路のうち連通部43が接続されている部位の流路断面積よりも小さく、かつ第2熱媒体流路のうち連通部43が接続されている部位の流路断面積よりも小さくなっている。【選択図】図1
