Manufacturing method of anti-condensation refrigeration device for variable-pitch system

1. The utility model relates to the technical field of wind power generation systems, in particular to an anti-condensation refrigeration device for a variable pitch system.

Background technique:

2. At present, in recent years, offshore wind power in the wind power industry has entered a large-scale development stage. Its pitch system has been subjected to environmental effects such as high temperature and humidity for a long time, and the conditions are harsh. Once it fails, it will cause major economic losses and serious social impacts.

3. In view of the current high temperature environment of the pitch system, higher requirements are put forward for the stability of the components in the pitch system cabinet, but the heat of the core components still cannot meet the operating conditions of the long-term high temperature environment, making the pitch system The problem of heat dissipation has become increasingly prominent.

4. There are generally two traditional cooling methods: air cooling and semiconductor cooling. The air-cooled heat dissipation method cannot dissipate the heat in such a large high temperature environment, and the cooling effect is limited; in such a large high humidity environment, the condensation generated by the semiconductor refrigeration will follow the operation (rotation) of the pitch system , Short-circuit the panels of other parts in the cabinet, reduce the creepage distance, and cause an explosion in severe cases.
