Thermal management system of hybrid electric vehicle

Abstract

The invention discloses a thermal management system of a hybrid electric vehicle. The thermal management system comprises an electric drive cooling loop and an engine cooling loop; the electric drivecooling loop is suitable for carrying out thermal management on an electric driving part through the electric driving part, and is provided with a first water pump and a first radiator; the engine cooling loop comprises a turbocharging cooling branch and a heat dissipation branch; the two ends of the turbocharging cooling branch are communicated with the two ends of the electric driving part correspondingly, and the turbocharging cooling branch is provided with a first valve and a turbocharger assembly; and the heat dissipation branch passes through an engine and is suitable for conducting thermal management on the engine, and the heat dissipation branch is provided with a second radiator. The hybrid electric vehicle thermal management system disclosed by the invention is relatively high in part integration degree, and has the advantages of high efficiency and energy conservation.

Description

technical field [0001] The present application relates to the technical field of hybrid electric vehicles, in particular to a heat management system for hybrid electric vehicles. Background technique [0002] There are technical bottlenecks in electric vehicles at the present stage, and electric vehicle users are faced with the problems of charging anxiety and mileage anxiety. Compared with pure electric vehicle solutions, hybrid vehicles are a very effective way to realize clean transportation and solve the anxiety of electric vehicle users at this stage. Advantageous new energy vehicle solutions. [0003] The core of the hybrid technology is to complement each other through the motor and the engine, learn from each other, and match each other so that the car engine can run in a high-efficiency range for a long time. In addition, when braking, the hybrid electric vehicle system solution can increase energy recovery technology, etc., which significantly improves the energy ...
