Integrated system for vehicle with vapor compression cycle and pump driven two-phase cooling cycle

摘要

In the present invention, a part of the liquid refrigerant circulating in the vapor compression cycle is guided to the electronic component to cool the electronic component, so that a separate cooling water flow path is not required, so the configuration of the flow path can be simplified, as well as boiling heat transfer of the liquid refrigerant. Because it is cooled by using the cooling water, the cooling performance can be improved more than when using the cooling water. In addition, by supplying a refrigerant that has absorbed waste heat from the electronic component while cooling the electronic component to the high-pressure side refrigerant of the vapor compression cycle, the coefficient of performance of the system can be further improved.
