Abstract

The invention discloses a shell-and-tube electrical automobile battery device with an enhanced radiation function, which comprises battery single bodies, a heat exchanger shell and an interceptor plate, wherein the plurality of battery single bodies are arranged in the heat exchanger shell; each battery single body is a battery bundle formed by placing a plurality of single batteries into a heat exchanger tube and connecting the single batteries in series or parallel or both series and parallel; the heat exchanger shell is also provided with a liquid inlet pipe for allowing a phase-change material or liquid to enter the heat exchanger shell, or a foam material is filled in gaps among adjacent battery single bodies and gaps between the battery single bodies and the heat exchanger shell; the interceptor plate for controlling the flow speed of fluid is also arranged in the heat exchanger shell; and the two ends of the heat exchanger shell are provided with cover plates. The device can realize the effective cooling of an entire battery module of a power battery in a severe hot environment, keep the temperature distribution balance among the battery single bodies and the temperature in the battery in a reasonable range for reaching the optimal operation condition of power equipment, prolong the service life of the battery, and improve the power performance of the power equipment.

Description

technical field [0001] The invention is a shell-and-tube electric vehicle battery device with enhanced heat dissipation function, which belongs to the modification technology of the shell-and-tube electric vehicle battery device with enhanced heat dissipation function. Background technique [0002] Because the internal chemical reaction of the power battery is not stable, when it is used at high temperature, it may cause violent chemical reactions and electrochemical reactions inside the battery, generating a lot of heat. If the heat accumulates quickly inside the battery without time to dissipate, the battery may There will be liquid leakage, outgassing, smoking and other phenomena, and in serious cases, the battery will burn violently and explode. Since the performance and quality of power equipment largely depend on the performance of the configured battery stack, especially the reliability, cycle performance and cost of the battery. The temperature imbalance caused by t...
