Description
Technical Field
[0001] This utility model relates to the field of heat dissipation of energy storage equipment, and more specifically, to a spray-type liquid cooling heat dissipation device for energy storage equipment. Background Technology
[0002] To accommodate as many energy storage devices as possible within a limited space, the battery packs in energy storage power stations are highly clustered, which can lead to insufficient heat dissipation. Under the influence of various internal and external factors, the temperature of the battery pack rises sharply, which can easily cause the battery separator to collapse and internal short circuits, resulting in thermal runaway and potentially causing a fire in the system.
[0003] Currently, the main types of cooling devices used for energy storage equipment on the market are water-cooled immersion type and spray type. Immersion type refers to completely immersing the battery pack in coolant to achieve heat dissipation, while spray type refers to spraying coolant onto the surface of the battery pack to remove heat. However, due to gravity, the sprayed coolant flows through the battery pack quickly, resulting in insufficient contact time, incomplete contact area of the coolant, and poor heat dissipation effect.
