Title:
THERMAL MANAGEMENT SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/236957
Kind Code:
A1
Abstract:
A thermal management system and a vehicle. A second heat exchanger (40) is connected in series to a second pipeline (200); a first heat exchanger (30) is connected in series on a first pipeline (100); the first pipeline (100) is connected in parallel to the second pipeline (200) by means of a first pipe section (300) and a second pipe section (400); a first multi-way valve (500) is provided at the inlet end of the first pipe section (300) or the second pipe section (400); by adjusting the opening degrees of ports in the first multi-way valve (500), when the first heat exchanger (30) and the second heat exchanger (40) work at the same time, part of a cooling liquid in the second pipeline (200) can enter the first pipeline (100) to adjust the temperature of the cooling liquid entering the first heat exchanger (30), so that the temperature of a device (10) to be liquid cooled (such as a battery) is controlled within a suitable range, the mass flow entering the second heat exchanger (40) and the temperature thereof can be ensured to be within suitable ranges, and the temperature of a structure (20) waiting for temperature adjustment (such as a passenger compartment) is adjusted to a suitable range. Thus, the effect of balancing the cooling capacity and temperature of the device to be liquid cooled and the structure waiting for temperature adjustment is achieved, and the structure and a control method of the heat management system are simplified.
