Description

technical field [0001] The invention relates to an air cooling device, in particular to a heat pipe type generator air cooling device, which belongs to the technical field of generator cooling. Background technique [0002] During the working process of the generator, a large amount of heat will be generated inside the motor due to various losses of the stator and rotor. If the motor is not cooled in time, the power generation efficiency will be reduced, and the motor will be damaged in severe cases. At present, air-to-air coolers are generally used for low- and medium-power generators to cool the generators. The existing air-to-air coolers are fixed on the top of the generator case, that is, the external fan of the cooler sucks the ambient air The air is heated up inside the heat exchange tube bundle and then discharged through the wind guide hood. The hot air inside the motor is sent into the cooler box by the auxiliary fan, so that the hot air exchanges heat with the oute...

Problems solved by technology

The cooling method of this structure needs to increase the air circuit circulation inside the motor, which not only increases the power loss of the circulating fan, but also increases the difficulty of sealing the inside of the motor. In addition, due to the flow of cold air inside the tube bundle, scaling Makes it more difficult to clean
