Comparison Of Water-Cooled And Air-Cooled Temperature Of Transformer

First, water cooling method

The water cooling method of the transformer is to distribute the heat generated inside the transformer through the water cooling device to the outside, so that the temperature inside the transformer can be reduced to a certain extent. The water-cooling method is characterized by large temperature reduction and large water flow, but it needs to consume more water resources. In the case of the same water flow, the heat dissipation effect of water-cooled method is better than that of air-cooled method.

Second, air cooling method

The air cooling method of the transformer is to distribute the heat generated inside the transformer to the outside through the wind path through the wind cooling device, so that the temperature inside the transformer is reduced. The air cooling method is characterized by saving water resources, but the heat dissipation effect is slightly worse than that of the water cooling method. Under the same heat dissipation, the air volume of the air-cooled method is larger than that of the water-cooled method.

Comparison of water-cooled and air-cooled modes

Both water-cooled and air-cooled transformers have their own advantages and disadvantages. If the heat dissipation requirements are high, you can choose water cooling method; If you want to save water, you can choose air cooling. In terms of temperature, the water-cooled method can reduce the temperature more than the air-cooled method, and the temperature of the transformer can generally be reduced to below 50 ° C; The air cooling method can reduce the temperature to about 60 ° C.

In summary, both water-cooled and air-cooled transformers can effectively reduce the temperature of the transformer, but the effect of the two methods will be different. When selecting the heat dissipation mode, comprehensive consideration should be made according to the actual situation.
