VEHICULAR HEAT MANAGEMENT SYSTEM

WIPO Patent Application WO/2017/043319

A1

The vehicular heat management system is equipped with a first heat medium circuit (11), a second heat medium circuit (12), a changeover unit (40), a communication part (43), and a device (44). The first heat medium circuit has a first heat medium flow path through which a heat medium circulates. The second heat medium circuit has a second heat medium flow path through which the heat medium circulates. The changeover unit switches between an independent mode in which the heat medium circulates in the first heat medium flow path and in the second heat medium flow path independently of each other and a cooperative mode in which the heat medium circulates between the first heat medium flow path and the second heat medium flow path. The communication part is arranged parallel to the changeover unit in terms of the flow of the heat medium, and allows communication between the first heat medium flow path and the second heat medium flow path. The device is disposed on the communication part. The flow path cross-sectional area of the communication part is smaller than the flow path cross-sectional area of the part of the first heat medium flow path where the communication part is connected, and is smaller than the flow path cross-sectional area of the part of the second heat medium flow path where the communication part is connected. According to this vehicular heat management system, pressure loss by the device can be reduced.
