What is the role of industrial chillers in the vacuum coating process? Vacuum coating works at a high temperature membrane surface evaporation falling crystals. As the air for evaporation of the membrane molecules will produce resistance caused by collision to make crystals become rough dull, it must be under high vacuum in order to make fine crystal bright, if not high vacuum will lose luster crystal bonding force is 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 film of precursor molecules will evaporate under the influence of an electric field to accelerate the bombardment target, a large number of target atoms sputtered, neutral target atoms (or molecules) is deposited a film on the substrate, can not be solved in the past 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. Currents flowing in a conductor skin effect, the charge will be gathered in the conductance have surface area, so that the conductance heat pipes do so using the hole conductors middle water cooling. (Mainly cylindrical target) Why should water cooling? Magnetron sputtering target at launch will generate heat will deform a gun, so it has a water jacket for cooling a gun. At the same time there is an important reason may magnetron sputtering coating technology is considered one of the most prominent 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 and to explore the more general principle of magnetron sputtering 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 achievements of technology. It sputtering rate, the substrate temperature is low, the film - a good base bonding force, stable performance of the device. Air-cooled chiller and water-cooled chillers and cooling functions is the same way, the overall structure and operation of the circuit in addition to the condenser, the other part is the same. Air-cooled chiller using fin condenser with fan forced air flow directly away refrigerant heat; water-cooled chiller using shell and tube condenser, cooling water constantly flowing away refrigerant heat dispersed through cooling towers the heat absorbed by the cooling water. Comparison of energy efficiency of heat transfer due to the different temperature, in the same outdoor ambient conditions, air-cooled chiller running than water-cooled condensing temperature is high, so in the same cooling capacity, the power consumption of air-cooled chillers It will be higher. From energy efficiency, it is generally a water-cooled unit cooling capacity than air-cooled unit to be higher than 300 ~ 500 Kcal / h. Hot and cold machine using the main features of the highest in Europe and America imported compressor head brass welding method using anaerobic heating power switching function RS485 communication function for automated management (optional) electrical use OMRON, FUJI, TE, LG, MOELLER, ABB temperature control range: water temperature + 5oC-98oC stainless steel integrated pipelines for less pipe resistance and rust using imported components, life is long control mode: imported for the computer or PLC (optional) Perfect safety protection, fault indication, maintenance, maintenance without professional high efficiency evaporator, can save more energy than 30% C-10 uses two compressors used independently or together.
