Problems solved by technology

However, during the charging and discharging process of the power battery pack, a large amount of heat will accumulate inside the battery. If the heat is not discharged in time, the temperature of the battery pack will rise sharply, resulting in thermal runaway, which will further cause the battery to release gas, smoke, and leak. liquid, it may even cause the battery to burn

Abstract

The invention relates to an automobile battery heat dissipation structure with a local water cooling function. The automobile battery heat dissipation structure comprises a front rotating disc, a backrotating disc, a rotor and a plurality of battery sub-modules, wherein the cross section of the front rotating disc is in a regular polygon shape, and a water mist fan is arranged on the outer side of the front rotating disc, spray nozzles forming an annular shape are arranged on the water mist fan, and an air nozzle is arranged between every two adjacent spray nozzles; the back rotating disc andthe front rotating disc are arranged in a front-and-back symmetric manner, an exhaust fan is arranged on the outer side of the back rotating disc, and a first guide hood is arranged on the exhaust fan; the front rotating disc and the back rotating disc are fixedly connected onto the rotor, and the rotor is connected with a driving motor; the battery sub-modules are erected between the front rotating disc and the back rotating disc and arranged at all corners of the front rotating disc, and cross sections of the battery sub-modules are consistent with that of the water mist fan. The device isefficient and energy-saving.

Description

technical field [0001] The invention relates to an automobile battery system, in particular to a partially water-cooled automobile battery heat dissipation structure. Background technique [0002] Lithium-ion batteries have the advantages of high working voltage, high energy density, long cycle life, and no memory effect, and become the first choice for power batteries, especially soft-pack lithium-ion batteries due to their high safety, high energy density, and high flexibility. , has become the power battery commonly used in electric vehicles. However, during the charging and discharging process of the power battery pack, a large amount of heat will accumulate inside the battery. If the heat is not discharged in time, the temperature of the battery pack will rise sharply, resulting in thermal runaway, which will further cause the battery to release gas, smoke, and leak. liquid, it may even cause the battery to burn. Therefore, the car battery needs an excellent heat diss...
