Embodiment Construction

[0063] Such as Figure 1-3 As shown, the present invention provides a thermal management system, which includes:

[0064] Battery pack 11 (preferably accumulator);

[0065] It also includes a heat pipe assembly, which includes a first evaporation end 8 of the heat pipe, a heat exchange end 10 of the heat pipe, and a second condensation end 14 of the heat pipe;

[0066] And the heat exchange end 10 of the heat pipe is arranged at the position of the battery assembly 11. When the battery assembly 11 needs to be heated, the heat exchange end 10 of the heat pipe can communicate with the first evaporation end 8 of the heat pipe, so that Heat is absorbed from the first evaporation end 8 of the heat pipe to heat the battery assembly 11; and when the battery assembly 11 needs cooling, the heat exchange end 10 of the heat pipe can also be condensed with the second heat pipe The end 14 is connected to release heat toward the second condensing end 14 of the heat pipe to cool the batter...

Abstract

The invention provides a thermal management system and its control method and a car, the thermal management system includes: a battery assembly (11); and a heat pipe assembly, the heat pipe assembly includes a first evaporation end (8) of the heat pipe and a heat exchange end (10) of the heat pipe and the second condensing end (14) of the heat pipe; The battery assembly (11) is heated by absorbing heat from the first evaporation end (8) of the heat pipe; ) release heat to cool the battery assembly (11). The invention can not only cool the battery, but also heat the battery, has a wider application range, and has simple pipelines in the heating and cooling system, thereby improving system reliability and operating efficiency.

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...
