With the high requirements and high standards of the electroplating process, the electroplating rectifier has entered the era of high-frequency switching power supply, and the DC electroplating process has been extended to the pulse plating process. There are several types of cooling during normal operation of the electroplated rectifier, namely air-cooled or forced air-cooled, water-cooled, and oil-cooled, which is widely used in the early days.
Air-cooling and water-cooling are two types of cooling methods used in today's electroplating rectifiers. The advantages of cooling, environmental protection and production cost savings are far superior to oil cooling.
In terms of air cooling, air cooling is the most widely used cooling method for various electronic equipments. It is because of the advantages of convenient movement, simple maintenance and good cooling effect. The air-cooled plating rectifier is produced by a fan. When the wind is dissipated, the fan is used for blasting or drawing air to increase the air flow speed inside the device to achieve the purpose of heat dissipation. The form of forced air cooling is mainly convection heat dissipation, and the cooling medium is air.
As for water cooling, it uses the circulating flow of water to take away the heat generated by the rectifier work. It is usually combined with a water circulation cooling system. Therefore, it can be seen that the water-cooled plating rectifier is more troublesome because its movement will drive the movement of some related equipment. In addition, the water supply has certain requirements for water quality, at least it should be ordinary tap water. Since the impurities in the water will form alkali adhesion in the water cooling tube, the water flow is blocked, and the cooling system Poor work, which in turn causes some potential problems such as equipment damage. This is also the biggest disadvantage of water cooling compared to air cooling, and water is a kind of consumable, which will indirectly increase production costs, and is completely free of charge to the air.
The above air-cooling and water-cooling have their own advantages and disadvantages, air-cooling, simple, but pay attention to the ventilation problems of the equipment, as well as the dust accumulated in the equipment in time; water cooling should pay attention to water quality problems, especially to check the water cooling pipe The problem of plugging is that the water-cooled plating rectifier can be closed and the corrosion resistance is better. After all, the air-cooling is to have a vent.
In addition to the cooling methods of air-cooled and water-cooled two kinds of electroplated rectifiers, there is also a cooling method called oil cooling. In the early days of thyristor rectifiers, oil cooling was more common. What is oil cooling？Oil cooling is similar to substation. The transformer uses mineral oil as a cooling liquid to dissipate heat and avoid any sparks. The corrosive problem is also serious. Therefore, compared with oil cooling, air cooling and water cooling obviously have better excellent characteristics.
