With my country's accession to the WTO, the industrial production and manufacturing industry in the society has entered a period of rapid development. At the same time, market competition is fierce and the requirements for product quality have been greatly improved. In fact, in the process of improving product quality, manufacturers have actually ignored a subtle but extremely important factor. In the technological production process, because the mechanical equipment will continuously emit heat during the technological production, when the heat exceeds the temperature of the material, the product information will be unstable and the product quality cannot be guaranteed. Taking plastic products and electroplating production as examples, the cooling time of plastic products in production accounts for more than 80% of the production cycle time. It can be seen that greatly reducing the cooling time is very important for process production, and chilled water can absorb heat in time , It can quickly reduce the temperature of the mold cavity, accelerate the qualitativeness of the product, and shorten the opening surface. In the electroplating process, frozen water can quickly reduce the temperature of the electroplating solution, and can maintain the temperature within a range, allowing metal molecules to attach to the current

The surface of the plated part can increase the surface and density of the product, so that the quality of the product can be better maintained.

One. Chemical industry: Mainly used for cooling of chemical reactors (chemical heat exchangers), to take away the huge heat generated by chemical reactions in time to achieve the purpose of cooling (cooling) and improve product quality.

2. Manufacturing industries of plastic products, plastic containers, food packaging films, medical packaging films, etc.

In the injection molding process of plastic products (televisions, computers, washing machines, mobile phones, refrigerators, air conditioners, plastic toys, automotive plastic parts, etc.), whether the product can be cooled (cooling down) in time and effectively will directly affect the appearance and appearance of the product. Rate, thereby affecting production efficiency, production costs and corporate profits.
