The cooler is composed of main components such as an induced draft fan, a cooling core body (the heat exchange element is a finned tube, where cooling water flows inside the tube and hot air flows outside the finned tube), a filter, a ventilation cabinet, and so on. Working process: The hot air emitted by the motor enters the cabinet, passes through a filter, cools the core, and is then fed into the motor by a fan to cool the motor, forming a closed circulation system
No contact thermal resistance, high heat transfer efficiency, fins can be made of copper or aluminum, easy to clean, not easy to scale, small product size, strong corrosion resistance, and light weight
Mainly used for circulating cooling of hot air in generators/motors
The heat transfer components are string finned tubes, wound finned tubes, and rolled finned tubes. The heat exchange tube is made of red copper, brass, and white copper. Aluminum alloy fins or copper fins. The pipe box is made of carbon steel
