AI Technical Summary
Existing electric forklift batteries suffer from problems such as small ventilation and high energy consumption, especially in poorly ventilated environments where the cooling effect is poor.
The patented heat dissipation device uses an aluminum alloy heat dissipation shell with an inner cavity filled with thermally conductive silicone oil. The combination of the aluminum alloy heat dissipation shell and the thermally conductive silicone oil achieves liquid cooling. The battery heat is conducted to the heat dissipation shell through the thermally conductive silicone oil and then dissipated by the heat dissipation fins.
This technology improves battery heat dissipation without increasing energy consumption, thus eliminating the need for a cooling fan.
