The invention provides a temperature adjusting system for a vehicle, which can restrain increase of friction loss of a rotating electric machine and a gear box. A temperature control system (10) for a vehicle is provided with: a first temperature control circuit (61) for controlling the temperature of an electric motor and a transmission; a second temperature adjustment circuit (62) that adjusts the temperature of the power conversion device; a heat exchanger that exchanges heat between the first temperature adjustment medium and the second temperature adjustment medium; and a control device. The control device is configured so as to be able to control the valve device on the basis of the temperature of the first temperature-adjusting medium detected by the first temperature sensor and the temperature of the second temperature-adjusting medium detected by the second temperature sensor, and to control the valve device when the temperature of the first temperature-adjusting medium is lower than the temperature of the second temperature-adjusting medium. The control valve device increases the flow rate to the second branch flow path compared to a case where the temperature of the first temperature adjustment medium is higher than the temperature of the second temperature adjustment medium.
本发明提供能够抑制旋转电机以及齿轮箱的摩擦损失的增加的车辆用温度调节系统。车辆用温度调节系统(10)具备:第一温度调节回路(61),其进行电动机、变速装置的温度调节;第二温度调节回路(62),其进行电力转换装置的温度调节;热交换器,其进行第一温度调节介质与第二温度调节介质之间的热交换;以及控制装置。控制装置构成为能够基于由第一温度传感器检测出的第一温度调节介质的温度和由第二温度传感器检测出的第二温度调节介质的温度来控制阀装置,在第一温度调节介质的温度低于第二温度调节介质的温度的情况下,控制阀装置以使向第二分支流路的流量与第一温度调节介质的温度高于第二温度调节介质的温度的情况相比增大。
