Detailed analysis of the selection of industrial chiller in the electroplating and electrophoretic oxidation industries


Many friends do not know how to select industrial chiller in the electroplating and electrophoretic oxidation industry, so this article will explain the selection of industrial chiller in the electroplating and electrophoretic oxidation industry in detail in this regard. For electroplating, electrophoretic coating, electroplating Production lines, anodizing, etc. are all aimed at cooling the plating solution in the plating tank. How to choose a chiller. There are two cooling methods, direct cooling and indirect cooling. Water-cooled chiller is directly refrigerated in the electroplating, electrophoresis and oxidation industries. The cooling principle: the water in the bottom of the cooling tower is pumped to the condenser of the chiller through a water pump to cool the condenser, and then flows back to the cooling tower for spraying and cooling The fan on the top of the tower cools the water and then flows back to the bottom basin of the cooling tower. The condenser dissipates heat while the refrigerant inside it is liquefied, and then flows into the evaporator inside the cold gun to evaporate, and the heat is absorbed during evaporation, so the sulfuric acid (tank solution) in the cold gun is cooled, and the cooled sulfuric acid is transported by the water pump To the electroplating, electrophoresis and oxidation industry tank, such a cyclic process.

Water-cooled chiller is indirectly frozen in the electroplating, electrophoresis and oxidation industry. The principle of refrigeration: the water in the bottom of the cooling tower is transported to the condenser of the chiller through a water pump to cool the condenser. When it flows back to the cooling tower and sprays down, the water is cooled by the fan on the top of the cooling tower, and then flows back to the bottom basin of the cooling tower, so it runs repeatedly. The condenser dissipates heat while the refrigerant inside it is liquefied, and then flows into the evaporator in the water tank to evaporate. During the evaporation, heat is absorbed, and the water in the water tank is cooled. The cooled water is sent to the heat exchanger (middle) by the pump Separated, one side of water, one side of sulfuric acid, and then the temperature of sulfuric acid is cooled by the process of heat transfer, just such a cyclic process. The advantage of this product is that it is easy to install, its service life is relatively longer than that of direct freezing, and acid and alkali are not easy to corrode the chiller. This type of chiller is generally a plate-enclosed heat exchanger.

In addition to this indirect cooling, another method is to coil the coil in the plating tank, and then the chilled water provided by the industrial chiller is circulated in the coil to cool the plating solution. In this way, ordinary chiller can meet the requirements.
