Thermal management system and control method thereof and auto

Abstract

The invention provides a thermal management system and a control method thereof and an auto. The thermal management system comprises a battery assembly (11) and a heat pipe assembly, wherein the heatpipe assembly comprises a first heat pipe evaporation end (8), a heat pipe heat exchange end (10) and a second heat pipe condensation end (14); the heat pipe heat exchange end (10) is arranged in theposition of the battery assembly (11), and the heat pipe heat exchange end (10) may be communicated with the first heat pipe evaporation end (8) to absorb heat from the first heat pipe evaporation end(8) to heat the battery assembly (11); the heat pipe heat exchange end (10) may also be communicated with the second heat pipe condensation end (14) to release heat to the second heat pipe condensation end (14) to cool the battery module (11). The invention cannot only cool the battery, but also heat the battery, realizing a wider range of application, and the heating and cooling system pipelineis simple, improving the reliability and operating efficiency of the system.

Description

technical field [0001] The invention belongs to the technical field of heating and cooling, and in particular relates to a thermal management system, a control method thereof, and an automobile. Background technique [0002] The battery of an electric vehicle has high temperature requirements, and the performance of the battery will be affected if the temperature of the battery is higher or lower than the optimal operating range. In summer, batteries of electric vehicles, compressors of air conditioners, and heating elements of controllers will generate a lot of heat during operation, and efficient heat dissipation is required, otherwise reliability and operating efficiency will be reduced; while batteries in winter need to be heated, and the outside of the air conditioner room When a high-quality heat exchanger is used as an evaporator, it is easy to generate condensation water, resulting in a short frosting cycle and reducing system performance and comfort. Existing elect...
