Problems solved by technology

With this structure, since the heat dissipation rib is a solid structure with two heat dissipation surfaces, the heat generated on the generator stator frame is dissipated through the two surfaces of each heat dissipation rib, so the heat dissipation effect is poor

Abstract

The invention discloses a stator frame of a generator. The stator frame comprises a frame body and cooling rib bars that are uniformly distributed at the outer peripheral surface of the frame body. The cooling rib bars have cavity structures; cooling plates are arranged in the cooling rib bars; a plurality of through holes are formed in the cooling plates, wherein the through holes are uniformly distributed at the cooling plates. Compared with the prior art, the provided stator frame enables the heat radiation area to be enlarged because of the cooling rib bars with the cavity structures; during heat radiation, the heat at the inner layers of the cooling rib bar cavities is transmitted to the outer-layer surface by the air medium and then is dissipated by the outer-layer surface. Therefore, the heat radiation speed is fast and the heat radiation effect is good; and the service life of the generator is prolonged.

Description

technical field [0001] The invention relates to a generator stator frame. Background technique [0002] With the development of generators, the heat dissipation requirements for generators are getting higher and higher. Now, there is a generator stator base, which will generate a lot of heat under the high-speed rotation of the rotor. If a fast and effective heat dissipation method is not adopted And the structure will affect the life of the generator. The current generator base includes a base and heat dissipation ribs, the heat dissipation ribs are installed on the outer circumference of the base, the heat dissipation ribs are solid structures, and the generator base is cast Into, the base and the heat dissipation ribs are integrated. With this structure, since the heat dissipation rib is a solid structure with two heat dissipation surfaces, the heat generated on the stator base of the generator is dissipated through the two surfaces of each heat dissipation rib, so that...
