What is the role of industrial chillers in vacuum coating process? Vacuum coating works by the membrane at a high temperature falling surface evaporation crystallization. Since the air for the evaporation of the membrane molecules will produce resistance cause a collision, a crystal was roughened matte, it is necessary under high vacuum to make the crystals fine bright injection freezer, fruit such as the degree of vacuum is not high crystal will lose luster binding force is also very poor. Early vacuum coating is to rely on natural evaporation body scattering, combined with low gloss poor poor ergonomics. Now add frequency magnetron sputtering target magnetron target shooting evaporated film of precursor molecules under the influence of an electric field to accelerate the bombardment target freezer, a large number of target atoms sputtered, neutral target atoms (or molecules) a film is deposited on the substrate, can not be solved in the past the natural evaporation process of membrane species, such as titanium zirconium oxide and the like. IF equipment cooling water must be added, because of its high frequency current is large. Current from flowing in a conductor skin effect, the charge will be gathered in the conductance has a surface area, such that the conductance heat pipe do so using the hole conductor intermediate water cooling. (Mostly cylindrical target) Why should water cooling? Magnetron sputtering target at launch will generate heat gun will shoot deformation, so it has a cooling water jacket to shoot a gun. At the same time there is an important reason may magnetron sputtering coating technology is considered one of the most outstanding achievements. It sputtering rate, the substrate temperature is low, the film - substrate with good adhesion. From a deeper study the movement of electrons in a non-uniform electromagnetic field, discusses the magnetron sputtering of a more general principle and transverse magnetic field inhomogeneity and symmetry is the essential reason for magnetic confinement. Magnetron sputtering coating can be considered one of the most outstanding technical achievements. It sputtering rate, the substrate temperature is low, the film - a good base binding force, stable performance of the device. Precautions when matters concerning the safe operation of the chiller when the chiller safe operation must be noted: 1. During installation, check the machine for damage air-cooled chillers, choose the right place for easy installation and future maintenance. 2. Install the unit floor area must be installed pad or foundation, and its level within 6.4mm of degrees, and can withstand the weight of the unit is running. 3. The chiller should be placed within the room temperature 4.4-43.3 ℃, the sides and top of the unit should have adequate space air-cooled screw chillers for routine maintenance work. 4. At one end of the unit should be set aside to clean the condenser tubes pumping tube space, but also can take advantage of openings or other location suitable hole. 5. Select the appropriate pipe diameter, maximum power operation unit cooling system and water system, and properly connected. 6. For normal applications, through the evaporator and condenser water flow rate is permitted between 1.0-3.6m / s.
