Air cooling radiator unit of power supply module for electrical vehicle and power supply module thereof

Abstract

The invention discloses an air cooling radiator unit of a power supply module for an electrical vehicle and the power supply module. According to the radiator unit, plastic supports, a radiating aluminum sheet, electrical cores and isolating cotton form a 2P electrical core unit which comprises two 1P electrical core units. The two 1P electrical core units are respectively adhered through two faces of the isolating cotton to the two electrical cores and are stacked up at intervals, and the outermost two plastic supports are mutually fastened as a whole. The invention also discloses a power supply module which comprises a cover plate and a pressure plate and also comprises 2P electrical core units arranged between the cover plate and the pressure plate, wherein the 2P electrical core units are mutually in series connection and stacked up. The structure of the device is optimized. By a gap radiating mode, a good radiating effect is realized, additional liquid cooling radiating structures are removed, and manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power supply equipment, in particular to an air-cooling heat dissipation unit of a power supply module for electric vehicles and a power supply module thereof. Background technique [0002] With the development of new energy vehicles in full swing around the world, more and more people pay attention to electric vehicles. The continuous upgrading of power equipment has higher and higher performance requirements for the power system, and a series of problems caused by poor heat dissipation of the battery have become increasingly prominent. At present, most new energy vehicles in the market often use liquid cooling or air cooling devices to realize the thermal management of the power system. However, the existing technology has caused an excessive increase in the weight of the vehicle to a certain extent, and has problems such as difficult arrangement and high cost, so it is difficult t...

Problems solved by technology

Although this structure can reduce the temperature difference between the inside and outside of the power module and the difference in continuous internal resistance, making the internal temperature consistent and the connection internal resistance consistent, but the first sub-unit and the second power unit that constitute the first power unit and the second power unit In the structure of the two sub-units, four-layer brackets, a layer of heat-dissipating aluminum sheet and foam cotton are used to fix the batteries. The application of the structural parts is cumbersome and complicated, which greatly increases the manufacturing cost. The batteries are directly clamped in the brackets. Shaking is caused, and the non-complete contact assembly between the battery cell and the aluminum sheet does not have a good heat dissipation effect, and the aluminum sheet needs to be connected to an additional liquid cooling device
