An integrated device for heating and cooling wind turbine gearbox

Abstract

The invention provides a heating and radiating integrated device for a wind driven generator gear box. The heating and radiating integrated device comprises a temperature collection module for collecting a temperature of the gear box, wherein the temperature collection module is connected with a control module; the control module is connected with a motor drive module and a heating and radiating module separately; the motor drive module is connected with the heating and radiating module; the heating and radiating module comprises a heating and radiating fin; a heating resistance wire is arranged in the heating and radiating fin; the heating and radiating fin is connected with a rotating shaft; and the rotating shaft is connected with the motor drive module. The motor drive module drives the rotating shaft to rotate and drives the heating and cooling fin to be clung to the gear box; and the heating resistance wire is opened or closed to heat or stop heating the gear box. The rotating shaft reversely rotates and drives the heating and cooling fin to rotate to be vertical with the wind driven generator gear box, so that radiating of the gear box is achieved. The quality of lubricating oil is not affected by indirect heating. The heating and radiating integrated device is simple in structure and convenient to maintain and repair, and integrates heating and radiating, so that the cost and the occupied space are reduced.

Description

technical field [0001] The invention relates to the technical field of wind-driven generator gearboxes, in particular to an integrated heating and cooling device for a wind-driven generator gearbox. Background technique [0002] The distribution range of wind turbines in my country is extremely wide, and they need to adapt to various complex environmental conditions in China, which brings multiple challenges to the design of wind turbines, especially the severe cold weather environment in winter poses a great challenge to the safe and stable operation of the turbines. [0003] In winter, the lubricating oil in the gearbox of the fan is generally in a low temperature state before the fan is shut down, which has a negative impact on the start-up of the fan, and the lubricating oil in the gearbox needs to be heated. With the fan running, the temperature of the gearbox may rise above the desired temperature, at which point heating is no longer required and cooling is required. ...

AI Technical Summary

Problems solved by technology

[0005] The traditional gearbox heating technology, whether it is an external lubricating oil heating device or a built-in immersion heating device, directly heats the lubricating oil. In actual use, it is often heated due to local overheating of the heater. The lubricating oil deteriorates in a short time, reducing the quality and life of the lubricating oil

In addition, two sets of devices for heating and heat dissipation are required, which occupy a large space and are not economical
