Batteries are important components on ships. During the operation of the ship, batteries provide power for electronic equipment on board. There are many types of batteries. Lithium battery modules are widely used in power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields because of their high storage energy density, long service life, high rated voltage, high power tolerance, strong high and low temperature adaptability and green environmental protection. Lithium battery modules will generate heat during operation. In order to avoid heat accumulation in the lithium battery module and cause damage, a heat dissipation device is needed to dissipate the heat of the lithium battery module.

[0003] Deficiencies of existing technology: Existing lithium battery mother modules mostly use cooling fans to quickly discharge the heat inside the lithium battery module when in use. However, the internal shape of the lithium battery module is irregular during use. At the same time, when the cooling fan is running, the fan blades rotate to push the air to generate wind, which is prone to eddy currents. This causes the air to be unevenly distributed when flowing inside the lithium battery module, resulting in uneven heat dissipation of the lithium battery module, affecting its use.
