The invention provides a technology capable of suppressing friction loss of a rotating electric machine. A temperature adjustment system for a vehicle is provided with: a first temperature adjustment circuit that adjusts the temperature of a motor and a generator; a second temperature adjustment circuit that adjusts the temperature of the power conversion device; and a heat exchanger that exchanges heat between the first temperature adjustment medium and the second temperature adjustment medium. The second temperature adjustment circuit is provided with: a first heat sink that exchanges heat between the second temperature adjustment medium and the outside air; a first branch flow path of a second temperature adjusting medium bypassing the heat exchanger; a second branch flow path of a second temperature adjusting medium passing through the heat exchanger; and a valve device that adjusts the flow rate of the second temperature adjustment medium to the second branch flow path.

    本发明提供一种能够抑制旋转电机的摩擦损失的技术。车辆用温度调整系统具备:第一温度调整回路,其调整电动机、发电机的温度;第二温度调整回路,其调整电力转换装置的温度;以及热交换器,其进行第一温度调整介质与第二温度调整介质之间的热交换。第二温度调整回路具备:第一散热器,其进行第二温度调整介质与外部空气之间的热交换;绕过热交换器的第二温度调整介质的第一分支流路;通过热交换器的第二温度调整介质的第二分支流路;以及阀装置,其调整第二温度调整介质向第二分支流路的流量。
