the cooling media for rectifier transformers

What is the cooling media for rectifier transformers?

Heat can generally be removed from the inverter using three media: air, water, and oil.

High-voltage inverters primarily generate heat through two main components: the rectifier transformer and the power components . Early transformers primarily used oil cooling, immersing the transformer in an oil tank. Because oil has a higher specific heat capacity and higher dielectric strength than air, this cooling method became the mainstream for high-power transformers. However, the oil requires maintenance, and sealing the lead wires is difficult. With advances in insulation materials, dry-type transformers have become dominant in small and medium-power transformers. Dry-type transformers are cooled by air. Water cooling is also possible, with the transformer's coils made hollow and filled with purified water to remove heat.

Rectifier transformers are widely used in various industries, mainly in lighting, machine tool electrical appliances, mechanical and electronic equipment, medical equipment, rectifier devices, etc. The product performance can meet the various special requirements of users. The electrochemical industry is the industry that uses rectifier transformers the most, electrolyzing non-ferrous metal compounds to produce aluminum, magnesium, copper and other metals; electrolyzing salt to produce chlorine alkali; and electrolyzing water to produce hydrogen and oxygen.
