Thermal management system for vehicle

A thermal management system for a vehicle, comprising:

• a first pump that draws and discharges a heat medium;
• a compressor that draws and discharges a refrigerant in a refrigeration cycle;
• a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the first pump;
• a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the first pump and outside air;
• and
• a controller that includes a pump control unit, wherein
• the pump control unit is configured to control an operation of the first pump such that the operation of the first pump is continued even after the compressor is stopped,
• the controller is configured to
• obtain a temperature of the outside air and a temperature of the heat medium, and
• determine whether the compressor is stopped and the operation of the first pump is continued,
• the controller determines whether a difference obtained by subtracting a temperature of the outside air from a temperature of the heat medium is equal to or less than a first predetermined value when the operation of the first pump is continued while the compressor is stopped, and
• the pump control unit stops the first pump when the controller determines that the difference is equal to or less than the first predetermined value.
