Circulating water cooling tower

The cooling principle of a closed-cycle cooling tower is, in simple terms, based on two cycles: an internal cycle and an external cycle. Without fillers, the main core consists of a copper tube surface cooler. ①Internal circulation: It connects with the target equipment to form a closed-loop system (the circulating medium is soft water). Cool the target device by removing heat from it to the cooling unit. ②External circulation: In a cooling tower, it is used to cool the cooling tower itself. It does not come into contact with the internal circulating water; heat is dissipated only through the copper tube surface coolers inside the cooling tower. Under this cooling method, the operation of the motor is controlled automatically based on the water temperature setting. Two cycles are required; when the environmental temperature is high in spring and summer, both cycles need to operate simultaneously. In autumn and winter, the ambient temperature is not high, and in most cases only an internal circulation is required.
