Automobile and cooling system

Abstract

Provided are an automobile and a cooling system. The cooling system comprises a heat exchanger, a waste gas pipeline, a battery heating loop and a heating control part, wherein the waste gas pipelinecommunicates with an exhaust pipe of an engine; the battery heating loop is connected with a battery of the automobile; the waste gas pipeline and the battery heating loop both communicate with the heat exchanger; and the heating control part is arranged in the battery heating loop and controls fluid in the battery heating loop to flow. The liquid flowing in the battery heating loop can absorb theheat of waste gas in the waste gas pipeline and further heat a battery, so that the energy utilization rate is improved. Furthermore, heat energy in the waste gas pipeline is subjected to heat exchange with the battery heating loop and then heats the battery, a certain heat energy loss is caused in the heat energy transmission process, heat energy carried in the battery heating loop is reduced, damage to the service life of the battery due to too high waste gas heat can be reduced, the waste gas pipeline and the battery heating loop are adopted for heat exchange, the complex pipeline design is not needed, and the structure is simple.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobiles, in particular to an automobile and a cooling system. Background technique [0002] When the power battery is used in a low temperature environment for a long time, the capacity of the power battery will be lost sharply. Traditional cars usually use the cooling pipes of the engine to heat the battery at low temperature, or directly heat the battery through the heat of the exhaust gas of the engine, or directly use the current of the battery itself for heating. [0003] However, when the ambient temperature of the battery is low, the effect of using the engine's cooling ducts to heat the motor is minimal. However, directly using the heat of the exhaust gas of the engine to heat the battery will cause damage to the battery due to the high exhaust gas temperature. When directly using the current of the battery itself for heating, it takes too long. [0004] Therefore,...
