Description

Technical Field

[0001] The utility model relates to the technical field of module cooling, in particular to a module cooling device. Background Art

[0002] Currently, there are three main cooling methods for modules; the first is natural cooling, which achieves cooling through the natural cooling of the battery cells. The advantages are low investment cost of the battery pack and simple structure. The disadvantage is poor cooling effect, which is generally used in low-end energy storage projects; the second is air cooling, which achieves cooling by installing blade fans inside the module. The advantages are low cost and simple structure. The disadvantage is general cooling effect. It is generally used in energy storage and low-end models; the third is liquid cooling, which mainly adds a liquid cooling plate at the bottom of the module and achieves cooling through the flow of coolant inside the liquid cooling plate. The advantage is good cooling effect. The disadvantage is high cost, relatively complex structure, and the risk of poor insulation due to leakage. It is generally used in high-end models and energy storage. Utility Model Content
