How is the chiller and the oxidizer chiller cooled? Water-cooled direct freezing in the electroplating (oxidation) industry refrigeration principle: the water in the cooling tower bottom basin is sent to the condenser of the chiller through the water pump to cool the condenser, and then flows back to the cooling tower to spray down and through the cooling tower top. The fan on the upper part cools down the water and then flows back to the bottom of the cooling tower, so that it runs back and forth. The oxidation chiller and the electroplating chiller condenser dissipate heat while the refrigerant inside is liquefied, and then flows into the evaporator in the cold gun to evaporate, and absorbs heat when evaporating, thereby cooling the sulfuric acid (tank) in the cold gun. The cooled sulfuric acid is pumped through the water pump to the electroplating (oxidation) tank, which is a cyclic process.
The air-cooled chiller contains a heat-insulating water tank and a water pump in its body, eliminating the need for an additional cooling tower to dissipate heat. Installation and movement are very convenient. However, it requires high working environment. First, the electroplating chiller and the oxidizing chiller are because It is cooled by hot air circulation, so if the ventilation effect of the installation workshop is not good, it will directly affect the cooling effect of the chiller. In addition, if you want to put the chiller in the dust-free workshop with humidity requirements, Then I advise you to modify the water-cooled. Because the air-cooled chiller will spray water vapor on the top of the machine to dissipate heat.
Water-cooled chillers can be divided into open type, sealed type (some called box type) and screw type. First of all, it must be stated that the water-cooled chiller must be additionally equipped with a cooling tower and a water pump to extract hot water for heat dissipation. In order to achieve a good cooling effect, water-cooled indirect freezing in the electroplating (oxidation) industry refrigeration principle: the water in the cooling tower bottom basin is sent to the condenser of the chiller through the water pump to cool the condenser. When it flows back into 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 of the cooling tower, so that it runs again and again. The condenser dissipates heat while the refrigerant inside is liquefied, and then flows into the evaporator in the water tank for evaporation, and absorbs heat during evaporation, thereby cooling the water in the water tank, and the cooled water is transported to the heat exchanger through the water pump (middle) Separating, one side of the water, one side of sulfuric acid,), the electroplating chiller and the oxidizing chiller then cool down the sulfuric acid through the process of heat transfer, thus 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 the acid and alkali are not easy to corrode.
It can be seen from the above that the direct freezing and indirect freezing of the chiller have the same effect, but it is obvious that the direct freezing chiller has no indirect freezing chiller safety, and the former equipment is easy to corrode and the life is relatively short. The price of direct refrigeration equipment is slightly superior, but the service life of the two is compared. The indirect refrigeration chiller is several times longer than the direct chiller, which can be used to calculate the value of the indirect chiller.
