IP23 wind power generator adopting direct cooling heat dissipation device

Abstract

The invention discloses a wind power generator and aims to provide an IP23 wind power generator adopting a direct cooling heat dissipation device, and the IP23 wind power generator is simple in structure and good in heat dissipation effect. The IP23 wind power generator includes a generator body and a heat dissipation device, the head end and the tail end of the generator body are correspondinglyprovided with a first air inlet and a second air inlet, the middle part of the generator body is provided with an air outlet, the heat dissipation device is arranged above the generator body, the heatdissipation device includes a shell, a cooling fan and a wind outlet, the bottom of the shell is provided with a first wind inlet and a second wind inlet which correspond to and communicate with thefirst air inlet and the second air inlet, a plurality of air suction openings are formed in the side wall of the shell, first air channels are formed between the air suction openings and the first andsecond wind inlets, the shell is provided with a vent opening matched with the air outlet, and a second air passage for discharging air inside the generator outwards is formed between the vent opening and the air outlet. By means of the IP23 wind power generator, the cost of manufacturing the heat dissipation device is saved, the power of the generator is improved, and the electricity cost is reduced.

Description

technical field [0001] The invention relates to the field of wind power generation heat dissipation, in particular to an IP23 wind power generator adopting a direct cooling heat dissipation device. Background technique [0002] At present, the cooling methods adopted by mainstream wind turbines in the market are: external air-to-air cooling with internal drive (IC616), external air-to-air cooling without internal drive (IC666), and external air-to-water cooling (IC86W). The above cooling methods are to ensure the IP grade (IP54) of the generator, and they are all primary cooling media (gas or liquid media whose temperature is lower than that of a certain part of the motor, which will be in contact with the part of the motor and take away the heat released by it. ) and the secondary cooling medium (gas or liquid whose temperature is lower than that of the primary cooling medium, the heat released by the primary cooling medium is taken away by the appearance of the motor or th...
