[0002] A considerable number of products on the market, such as chips, semiconductor components, LCD panels, batteries or auto parts, contain a lot of high-purity chemicals. The production of chemicals is inseparable from the use of production equipment. During production, many chemicals require raw materials to react at a relatively low temperature. However, it is often difficult to stabilize the production temperature by relying solely on conventional production equipment to ensure that the above chemicals can be produced effectively.

However, common cooling water supply devices often rely on heat exchangers to cool the water directly, and the water with a certain temperature after cooling is cooled again by the heat exchanger. Under this method, due to the temperature difference required for cooling, the performance requirements of the heat exchanger are very high, and the power consumption is large, it is not energy-saving, and the cost is high.
