Heat dissipation mechanism for gearbox of wind driven generator

Abstract

The invention discloses a heat dissipation mechanism for a gearbox of a wind driven generator. A horizontal partition plate is fixedly arranged in an outer case, a water-cooling heat dissipation mechanism is installed at the upper end of the partition plate, a heat dissipation pipe is connected with the water-cooling heat dissipation mechanism, and the heat dissipation pipe extends downwards to the position below the partition plate; and the gear box is located in the middle of the lower end of the outer case, connecting frames are fixedly connected with the lower end of the partition plate, the two connecting frames are located on the two sides of the gear box correspondingly, and the connecting frames are parallel to the side wall, provided with a heat dissipation opening, of the outer case. According to the heat dissipation mechanism, two heat dissipation fans drive air around the gear box to distribution rapidly, low-temperature air dissipates heat of the gear box, the heat dissipation effect on the gear box is improved through air cooling circulation, meanwhile, circulated distribution cooling water in a water cooling heat dissipation mechanism conducts the heat of the gear box, and air cooling and water cooling are carried out synchronously, so that the heat dissipation efficiency and the heat dissipation effect of the gear box are ensured.

Description

technical field [0001] The invention relates to the technical field of gear box heat dissipation, in particular to a heat dissipation mechanism for a wind power generator gear box. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The gearbox is an important mechanical component that is widely used in wind turbines. Its main function is to transmit the power generated by the wind wheel under the action of wind force to the generator and make it obtain a corresponding speed. However, after the existing wind turbine gearbox works for a long time, the meshing gears in the gearbox rotate A large amount of heat energy is generated, which affects the working performance of the gearbox. Long-term high temperature causes damage to the internal structure of the gearbox and affects the service life of the gearbox. Therefore, it is necessary to quickly...

Its main function is to transmit the power generated by the wind wheel under the action of wind force to the generator and make it obtain a corresponding speed. However, after the existing wind turbine gearbox works for a long time, the meshing gears in the gearbox rotate A large amount of heat energy is generated, which affects the working performance of the gearbox. Long-term high temperature causes damage to the internal structure of the gearbox and affects the service life of the gearbox. Therefore, it is necessary to quickly dissipate heat from the gearbox to improve the working performance and service life of the gearbox.

[0003] The publication number is: the patent of CN110375061A discloses a gear box heat dissipation system and its gears. Compared with this application, it cannot solve the problem proposed by this application: after the existing wind power generator gearbox works for a long time, the gear The rotation of the meshing gears in the box generates a lot of heat energy, and the cooling effect of the gearbox is poor, which affects the working performance of the gearbox. Long-term high temperature causes damage to the internal structure of the gearbox and affects the service life of the gearbox. Therefore, it is necessary to quickly dissipate heat from the gearbox To improve the working performance and service life of the gearbox
