A heat exchange system

By introducing a temperature sensor and controller into the heat exchange system to regulate the speed of the circulating pump, and combining this with the high-level water tank and booster pump to regulate pressure and temperature, the problem of low heat exchange efficiency caused by the fixed speed of the circulating pump is solved, achieving dynamic adjustment and efficient heat exchange.

AI Technical Summary

Technical Problem

The speed of the circulating pump in the existing heat exchange system cannot be dynamically adjusted according to the actual situation, resulting in poor heat exchange efficiency.

Method used

The first temperature sensor detects the cooling water temperature. The controller adjusts the speed of the circulating pump according to the temperature signal, and adjusts the pressure and temperature of the circulating loop through the high-level water tank and the booster pump to form a semi-closed circulating loop to dynamically adjust the cooling water flow rate and temperature.

Benefits of technology

It enables dynamic adjustment of the circulating pump speed, improves heat exchange efficiency, avoids excessive or insufficient pressure, ensures appropriate cooling water temperature, and enhances the heat exchange effect.
