A battery heat exchange module, system, energy battery and new energy vehicle

Abstract

The invention discloses a heat exchange module for a battery, a system, an energy battery and a new energy vehicle, and mainly relates to the technical field of new energy batteries. It includes a temperature control flat belt distributed in a serpentine shape between the rows and columns of the battery cells, the temperature control flat belt includes a composite flat tube, and the composite flat tube is composed of a plurality of pipeline units arranged linearly and vertically. There is a cooling medium circulating in the unit. The two ends of the composite flat tube are provided with a medium inlet and a medium outlet. A control valve for controlling the circulation of the cooling medium is installed on the medium inlet, and the cooling medium is used for heat dissipation or heating of the cell. Provides heat exchange; the outside of the composite flat tube is wrapped with a phase-change heat-conducting sheet, the phase-change heat-conducting sheet is U-shaped, and a gap is set between its bottom and the bottom of the temperature control flat belt, and a temperature sensor is installed in the gap. The beneficial effects of the present invention are: bidirectional high-efficiency heat exchange control on the temperature of the energy battery, delaying the life of the battery and maintaining the performance of the battery.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a heat exchange module for batteries, a system, an energy battery and a new energy vehicle. Background technique [0002] In order to improve the ecological environment and ease the pressure of oil consumption, the automotive industry needs to undergo revolutionary changes. According to the "Administrative Regulations on the Access of New Energy Vehicle Manufacturers and Products" by the Ministry of Industry and Information Technology, new energy vehicles are completely powered by rechargeable batteries. As the core component of new energy vehicles, the battery has strict requirements on the working environment, and the temperature is too high or too low, which has a great impact on the working efficiency and life of the battery. When the ambient temperature is too low, the chemical reaction rate inside the battery will be limited, the internal resistance of the bat...

AI Technical Summary

Problems solved by technology

[0003] At present, the cooling methods of new energy vehicle batteries are relatively comprehensive, such as air cooling method, liquid cooling method, phase change material cooling method and heat pipe cooling method, etc. The battery preheating method is also applied, but with the change of battery structure The battery pack is changed to a single multiple cylindrical batteries, blade batteries, etc., and its heat dissipation and preheating management are relatively strict, and currently on the market, the heat dissipation, preheating and its control system can be integrated to control such as 18650 and blade batteries. There is still no more suitable product and control system for this kind of battery
