In the process of product production, the extruder first undergoes a heating process to shape the plastic. During this process, the plastic product will come out in a medium to high temperature state. If natural cooling is used, this time will be relatively slow. In order to improve the production efficiency of the product, a chiller will be used to quickly cool the product. There are two cooling modes in the extruder field: first, die head cooling, and second, direct product cooling1： The die head is cooled by directly cooling the extrusion grinding tool of the extruder, and the chilled water is directly introduced into the die for cooling.2： The product is directly cooled, and after the plastic product is extruded by an extruder, there will be a water tank through which the product passes. During this process, the product temperature is rapidly cooled, and the chiller keeps the water temperature constant at a lower temperature to ensure the cooling effect of the product.

During the process of processing products, electroplating and electrophoresis will use a rectifier to introduce current into the electroplating tank, plating the metal in the electroplating solution on the surface of the workpiece. Under the action of the current, the temperature of the electroplating solution will continuously rise. When the temperature is too high, it will cause defects in the coating layer of the product. At this time, a chiller is needed to control the temperature of the electroplating solution. There are also two cooling methods in the electroplating field: indirect cooling. Because the electroplating solution is generally corrosive in acidic or alkaline conditions, customers usually coil some corrosion-resistant titanium tubes in the electroplating tank, and then the cooling water is cooled once through the titanium tubes.Direct cooling refers to making corrosion-resistant materials in the evaporator of the chiller, and directly passing the electroplating solution into the chiller to cool down before returning to the electroplating tank.

Many mechanical processing equipment generates heat during processing and production. In order to increase the service life of mechanical components, we need to use a chiller to cool the machinery. For example, machining centers, precision carving machines, CNC machine tools, etc. will generate a large amount of heat during the processing. During this process, a chiller is needed to cool it down and extend its service life.

Industrial refrigerators are mainly used in the chemical industry for cooling and cooling chemical reaction vessels (chemical heat exchangers), timely removing ordinary heat generated by chemical reactions to achieve the purpose of cooling and improving product quality.
