Description

Technical Field

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. During the power generation process of the generator, a large amount of heat will be generated due to the mechanical drive, which needs to be cooled and dissipated through a cooler.

[0003] The fans used in existing wind turbines are mostly volute-shaped, that is, R-shaped. Since the shell guides the air sucked into the fan, the air volume is relatively small. In addition, conventional generators use fans to form an external air path and centrifugal impellers to form an internal circulation air path. The internal and external airflows exchange heat in aluminum tubes, which not only has poor thermal conductivity, but also has large mass and high manufacturing cost. Utility Model Content
