Battery thermal management system with air cooling mechanism

Abstract

The invention discloses a battery thermal management system with an air cooling mechanism. The battery thermal management system comprises a bottom shell, the top end of the bottom shell is connected with a top cover in a clamped mode, the bottom end of the bottom shell is rotatably connected with a liquid cooling mechanism, the bottom of the inner wall of the bottom shell is connected with a heat exchange mechanism in a clamped mode, and the top end of the top cover is fixedly connected with the air cooling mechanism. The invention relates to the field of new energy automobiles. A cushioning base and a cooling plate complete heat dissipation and cooling treatment through the liquid cooling mechanism, efficient heat dissipation protection of the device on the battery pack is achieved, the lower protection plate is matched with the air cooling fins to provide air cooling heat dissipation protection for the water tank, and the cooling effect of the liquid cooling mechanism is improved; and air with little heat radiation is provided for the device through the air inlet pipe and the flexible adjustable air guide pipe for air cooling heat dissipation, the device is prevented from directly obtaining hot air from the road surface, and the heat dissipation efficiency of the device is improved. The problems that an existing battery thermal management system with an air cooling mechanism is low in cooling efficiency, insufficient in anti-explosion protection and inconvenient to maintain are solved.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a battery thermal management system with an air cooling mechanism. Background technique [0002] The batteries used in the battery packs of new energy vehicles are mainly divided into lithium iron phosphate batteries and ternary lithium batteries. Among them, lithium iron phosphate batteries have the problems of poor low temperature performance and low energy density, and ternary lithium batteries have poor safety and are not resistant to high temperatures. and the problem of elemental toxicity. [0003] The existing patent (notification number: CN111883877A) discloses an electric vehicle battery thermal management device that combines air cooling and liquid cooling, including a box body and multiple rows of battery packs arranged in the box body, and each row of battery packs is composed of multiple cells. Each single battery is embedded in a composite phase change material b...
