Description

Technical Field

[0001] The utility model relates to the technical field of water-cooled generators, in particular to a new type of water-cooled generator. Background Technique

[0002] In high-power equipment systems such as generators, transformers, and control cabinets, coolers are essential as heat dissipation devices. They mainly absorb the heat generated during system operation for heat exchange to keep the temperature of the system body within the specified range.

[0003] When the existing silent diesel generator set operates, the generator relies on air to cool the stator and rotor. A fan needs to be equipped at the flywheel end of the generator, and an air inlet needs to be equipped at the rear end.

[0004] The air outlet of the existing silent diesel generator set is relatively large, resulting in a longer motor length. When installing at the air inlet of the motor, an air inlet space needs to be reserved. During the installation of the generator set, it is also necessary to avoid the hot air at the air outlet from flowing back into the air inlet, which may cause the heat dissipation of the generator to fail and the generator set to shut down due to high temperature.

[0005] Through the C-type water-cooled structure generator, it is possible to achieve that the motor does not require air inlets and outlets, reduce the length of the generator, and enable the generator set to not need to consider reserving space for the air inlet. Content of the Utility Model
