- Structure & Working Principle

Structure & Working Principle
The cooling water tank features a well-designed circulating structure, making it easy to operate and maintain. It consists of a vortex pump, a circulating cooling system, a radiator, a cooling fan, and a high-temperature-resistant plastic water tank.
Water stored in the tank is pumped into the vortex pump for pressurization. It then flows through the circulating system to the equipment that requires cooling. The heated water returns to the radiator, where heat is dissipated by the cooling fan. After cooling, the water flows back into the tank and re-enters the circulation system, achieving continuous cooling.
