What are the applications of chillers?
The laser industry is mainly used in laser marking machines, laser engraving machines, laser welding machines, laser printers, laser cutting machines, etc. It can precisely control the temperature required by laser equipment, thus ensuring the laser equipment. normal work. Additional sources of cooling may be required for laser generation sources, beam controllers, and electrical control cabinets in laser (laser) systems. The freezing water temperature requirement is usually between 15-22 °C, and the accuracy of the frozen water is usually ±1K or ±2K. Some equipment may require ±0.5K, and some other equipment have certain requirements for the conductivity of the frozen water and corrosion resistance. Therefore, the water quality requirements are very high, and the pipes are made of stainless steel or PVC pipes. For special applications in laser systems, industrial chillers can be specifically designed to meet different requirements. 2. Food industry It is used for high-speed cooling after food processing to adapt it to packaging requirements. There is also a temperature for controlling the fermented food. 3, plastic industry chiller used in plastic processing machinery molding mold cooling, can greatly improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, so that the product does not shrink, no deformation, easy to release plastic products, accelerate products Styling, which greatly improves the production efficiency of plastic molding machines. The plastic pellets are melted into the mold after being heated and melted, and then the mold is extruded to form a plastic workpiece. In the continuous production process, the mold is cooled to shorten the plastic setting time, improve the dimensional accuracy of the workpiece, and the molding quality and surface quality. . The cooling capacity of the chiller is related to the injection volume of the injection molding machine. The larger the injection volume, the greater the required cooling capacity. The production of plastic containers (blowing bottles) and packaging films is even more inseparable from the chiller: in the production process, if the containers cannot be cooled in time, the containers produced will not be full of uneven thickness, and the color will not be bright or even shaped. The quality is low, and the production of the packaging film cannot be produced without the cold water (wind) cooling molding. Cooling with cold water (wind) provided by a chiller not only greatly improves product quality but also increases production efficiency. 4, the glass industry will generally heat the glass after high temperature and then quickly cooled, the temperature of the cooling water can not be too high or it will affect the quality of tempering. The industrial chiller is used to provide the frozen water for cooling, and the water temperature does not affect the influence of the ambient temperature to ensure the quality of the product. 5, electroplating industry in the electroplating industry oxidation, electrophoresis industry, chiller to help stabilize metal and non-metal ions, so that metal ions quickly attached to plating parts, oxidation parts, electrophoresis parts, not only increase density and smooth, and can reduce plating In the electroplating production, the electroplating solution generates heat in the electroplating reaction, so that the temperature of the electroplating solution is gradually increased. When the temperature of the electroplating solution is higher than the requirements of the process, the plating of the electroplated product is firm. Uniformity, flatness and appearance have a great influence. The freezing provided by the chiller is required to connect or cool the components at a specific temperature during the production process of the electronic components, and the functional parameters of the electronic components are controlled in a preset state. The constant temperature of the water to cool and connect the plating solution will greatly improve the electroplating production process and production efficiency. 6. Coating industry A. Vacuum film: The medium frequency vacuum coating machine is generally equipped with a chiller as the cooling device of the coating machine (mainly cylindrical target). The intermediate frequency equipment must be supplied with cooling water because of its high frequency and high current. The current has a skin effect when the conductor flows, and the electric charge will accumulate on the surface area of the conductance, so that the conductance is heated, so the mesoporous tube is used as the middle of the conductor to add water to cool. B. Ion plating: surface treatment of watches, parts, jewelry, jewelry, daily hardware, plumbing equipment, craft jewelry, plastic products, sanitary ware, locks, lamps, tableware and other handles. The ionization source needs to be heated and started during the initial work, and needs to be cooled during operation. The failure of the cooling system will cause damage to the ionization source. The cooling water must be cooled by a high pressure water pump to a cooling channel in the ionization source to cool the ionization source. C. Coated glass: often requires a large cooling unit, usually using a combination of multiple screw chillers. The coating line needs to be heated to reach a certain temperature before starting. After starting, it needs to be cooled by chilled water to maintain a lower temperature due to its own heat generation. 7. Reactor special chiller for reaction kettle industry Features: It adopts imported low-temperature compressor, automatic computer controller, refrigeration pipe material is “titanium”, high-efficiency heat exchanger, also uses well-known brand accessories, temperature control range It is widely used in fine chemicals, food additives, corn deep processing (starch), pharmaceutical, pharmaceutical storage, etc. at -80 °C ~ 20 °C. 8. Pharmaceuticals and biological products industry Low temperature and low humidity environment are required during production and storage. The low-temperature chiller can use ethylene glycol as the coolant to provide 5...-15 °C freezing liquid to provide the necessary cold source for low temperature and low humidity. When it is necessary to cool in winter, the unit can be equipped with a special control system, so that the unit can still maintain cooling operation at a low temperature of -15 °C. 9. Electronic product industry During the manufacturing process of the circuit board, heat is generated when the copper surface of the copper plate is corroded, so that the temperature inside the corrosion cell rises, affecting the quality of the circuit board, and the temperature of the corrosion pool can be protected by using an industrial chiller. Circuit board cleaning: The industrial chiller can reduce the temperature of the cleaning agent and condense the gaseous cleaning agent to effectively prevent the evaporation of the cleaning agent. The electronic components and the circuit board are cleaned, and the cleaning agent will be volatilized into the air. The cleaning agent is condensed by passing the frozen water/refrigerant through the copper tube/titanium tube, and the cleaning pool maintains a moderate temperature to reduce the evaporation of the cleaning agent.
