Abstract

The invention relates to a power battery module group and a heat radiation system thereof. The power battery module group comprises a casing, and several cells which are arranged in the casing. The heat radiation system comprises the following components: a heat radiation component which is arranged on at least one side surface of the casing; the heat radiation component comprises heat radiation air channels which are arranged at external sides of corresponding sides of the casing, and air supply units for blowing air into the heat radiation air channels; the heat radiation air channels and the inside of the casing are communicated, and gas which is blown by the air supply units is used for radiating heat of the cells in the casing. The heat radiation component of the heat radiation systemis placed outside the power battery casing, in order to facilitate installation of air supply units and sealing design of inlets; and the product has system installation convenience and simple latermaintenance, and installation convenience is guaranteed; the heat radiation air channels are positioned outside the battery casing, so that cleaning and dustless state in the casing are effectively maintained, and air channels are convenient to clean.

Description

technical field [0001] The present invention relates to a power battery module, and more specifically, to a power battery module and a cooling system thereof. Background technique [0002] As the global energy crisis and environmental problems are intensifying, the traditional automobile industry is facing unprecedented severe challenges. As a new type of energy-saving and environmentally friendly vehicle, pure electric vehicles have the advantages of low energy consumption, simple structure, low vibration and noise, and no pollutant emissions. They have become an important direction for future automotive development. [0003] Lithium-ion power batteries have become the first choice for electric vehicle power batteries due to their high operating voltage, high specific energy and specific power, low self-discharge rate, long cycle life, no memory effect, and no environmental pollution. The power battery pack generates a lot of heat during the operation of the car. If the he...
