Integrated water-cooling power battery box for electric bus

Abstract

The invention discloses an integrated water-cooling power battery box for an electric bus. The integrated water-cooling power battery box comprises a battery box, a cooling module and a battery core module, and is characterized in that the cooling module and the battery core module are both arranged in the battery box to form an integrated structure so as to make the equipment structure of the power battery box compact, efficient and miniaturized, save the occupied space of the equipment and save the manufacturing and using cost, the cooling module is in contact with the surface of the battery core module, a circulation loop is communicated in the box wall of the battery box, and is communicated with the cooling module, a circulation flow channel for a temperature adjusting medium to circularly flow is formed outside the box wall of the battery box, the temperature adjusting medium flows to the circulation loop through the circulation flow channel, the temperature adjusting medium in the circulation loop uniformly absorbs heat on the battery core module through the cooling module so as to cool the battery core module, and the heat source temperature of the battery core module is reduced through the cooling module, so that the cooling effect is achieved, and the heat dissipation effect and the heat dissipation efficiency of the battery core module are improved.

Description

Technical field [0001] The present invention relates to the field of power cells, in particular, to a one-piece electric pine-cooling power battery oven. Background technique [0002] In recent years, the electric bus has frequently upgraded, and the product iteration has continued growth, and the performance continues to improve. With the improvement of equipment performance, the increase in heat generation is increased, and the heat of electric bus has a great impact on the speed of the car, in high The temperature is rapidly increased under load, in order to ensure the safety of the car, some manufacturers often use the "reduction frequency" means to achieve the cooling effect, although there is a certain cooling effect, but the speed has also generated a large impact, but also affects the user driving experience. . [0003] At present, there are also some heat sinks to cool down, but the existing heat sink is substantially all-aluminum radiator or copper radiator, such radiat...

Problems solved by technology

[0010] In view of the existing technology, the structure of the water-cooled battery box is relatively complex, the heat dissipation effect is not ideal, the efficiency is low, the space is relatively large, thermal runaway is prone to occur, and there are potential safety hazards. It is necessary to add a frame and a support module to fix the battery cell and increase the number of parts. , also increased the cost, inconvenient assembly and other deficiencies, the technical problem to be solved by the present invention is to provide a heat exchange device that can make the heat exchange equipment compact, efficient, miniaturized, good heat dissipation effect, fast heat dissipation efficiency, without adding frames or The support module fixes the battery cells, reduces parts and costs, and is a water-cooled power battery box that facilitates equipment assembly
