Abstract
The invention relates to a heat pipe-PCM coupled thermal management module with a temperature-controlled thermal switch, including a power battery pack and a thermal management system. Several battery cells are arranged in the battery box, and the adjacent battery cells and the outermost battery surface The phase change material is filled in the gap with the box body; heat pipes are arranged in the phase change material to form a phase change material heat pipe coupling heat dissipation module; a thermal switch is installed at the condensing end of the heat pipe, and ribs are installed at the bottom, and the ribs extend to the air duct; the air duct is arranged in The bottom of the box utilizes the natural wind that exists when the car chassis is driving, and there is no excess power consumption; the thermal switch is formed by the cooperation of the upper heat pipe splint and the lower rib, and the action mode is composed of temperature sensors that are evenly distributed between the battery surface and the phase change material electric control. The invention has the advantages of simple and stable structure, good operation stability, etc., can keep the temperature of the battery group within the working range and has good uniformity, and can adapt to the requirements of different electric equipment after the battery group is connected in series and parallel, and has a wide application range.
Description
technical field [0001] The invention belongs to the field of battery heat management, in particular to a heat pipe-PCM coupled heat management module with a temperature-controlled heat switch. Background technique [0002] Due to its low energy consumption and zero emission characteristics, electric vehicles are well adapted to the requirements of energy saving and emission reduction, and have developed rapidly in recent years. Among them, the temperature of the power battery pack has always restricted the promotion and use of electric vehicles. Whether it is a traditional lead-acid battery or the current nickel-metal hydride or lithium-ion battery, the temperature has a very significant impact on the performance of the battery. If the temperature is too high or Too low is not conducive to the performance of the battery. Considering the annual temperature difference and the large daily temperature range in most parts of our country, it is necessary to carry out thermal mana...
