Generator Cooling

Air coolers are primarily used for large generators/motors. By cooling the air/hydrogen inside the generator/motor with cooling water, the temperature inside is maintained below a safe level, which is extremely important for ensuring the normal and continuous operation of the unit.

This product is an air cooler that cools the air inside the generator/motor that generates heat as it rotates using water. It is used in large rotating machines such as generators and motors in various fields such as power generation, transmission, and industry. The cooling element was developed using a proprietary technology with reliable performance. The cooling pipes can be made of corrosion-resistant stainless steel or copper alloy pipes. The fins are made of copper or aluminum with a lattice structure, and are tightly combined with the cooling pipes using expansion heads to improve heat transfer efficiency. The cooling pipes can be single-pipe or double-pipe structures, and the double-pipe structure can detect corrosion and prevent leakage. With a focus on large capacity, low air resistance, compactness, and lightweight design, the air cooler is designed to be customizable for customers' needs, resulting in a high-quality product.

The iron core and coil's temperature will steadily rise while the generator is running as a result of copper and iron loss. The temperature of the coil must not rise above a specific level in order to slow the rate of aging and extend the life of the insulation. Therefore, steps must be taken to promptly remove the heat produced by the coil and iron core in order to maintain the coil insulation's temperature below the set limit. The three cooling techniques that are most frequently employed are air cooling, hydrogen cooling, and water cooling.

  Before the air is sent into the generator, the air cooler (air cooler) employs cooling water to cool the air with a higher temperature coming out of the generator. In actuality, the cooling water removes the heat produced by the generator while the air just serves as a medium.

For big generators with effective cooling because of the weak cooling impact of air, hydrogen cooling and water cooling are frequently used.

The stator and rotor coils produce heat while the generator is working. The hydrogen inside the generator absorbs the heat. In order to exchange heat with the cold water in the water pipe, the hot hydrogen is pushed into the hydrogen cooler's pipeline. The heat released transforms into cold hydrogen, which is then compressed. Inside the generator, this cycle is repeated, and the hot water is pushed out and replenished with cold water. They exchange heat in the hydrogen cooler, which functions similarly to a refrigerator's condensing chamber. Why hydrogen, you ask? High-power generators are cooled with hydrogen or water while small-power generators are entirely air-cooled since hydrogen absorbs heat more than air.

  A reputable company, Vrcoolertech manufactures a variety of heat exchangers, including corrugated and finned heat exchange tubes as well as air heat exchangers (radiators), air coolers, and air coolers.
