Abstract

The invention discloses a microchannel-based cylindrical power battery thermal management device. The microchannel-based cylindrical power battery thermal management device comprises a battery pack, a circulating pump, a heat exchanger, an upper liquid storage box and a lower liquid storage box; the upper liquid storage box is arranged on the upper head face of the battery pack; a general cooling liquid outlet is formed in the upper liquid storage box; the lower liquid storage box is arranged on the lower head face of the battery pack; a general cooling liquid inlet is formed in the lower liquid storage box; the general cooling liquid inlet is connected with one end of the circulating pump; the other end of the circulating pump is connected with one end of the heat exchanger; the other end of the heat exchanger is connected with the general cooling liquid outlet; and therefore, a cooling circulating system is formed. According to the invention, the temperature control and liquid leakage problems of the power battery in severe environments and under extreme working conditions are solved.

Description

technical field [0001] The invention relates to a power battery heat management device, in particular to a microchannel-based cylindrical power battery heat management device. Background technique [0002] With the development of the world economy, the problem of energy utilization has become increasingly prominent. In recent years, people have paid more and more attention to the development of new energy. In the automobile industry, due to the problem of exhaust emissions, it has a great impact on the environment. Therefore, a new type of energy is needed to replace fossil fuels such as petroleum. The development of power batteries has solved the problem of exhaust emissions and reduced environmental pollution. pressure. Electric vehicles are powered by batteries, are clean and pollution-free, and are cheaper than fossil fuels such as oil. However, because the power battery generates a lot of heat in harsh environments, the temperature inside the battery will rise, which ...
