Heat radiating device of inner wall of wind turbine generator system

Abstract

The invention discloses a heat radiating device of an inner wall of a wind turbine generator system. A whole is formed through an air discharging barrel, a filtering net, a stopping cover, an upper fixing ring, a vertical air guide plate, a horizontal air guide plate and a lower fixing ring, high temperature air at the upper portion of a tower of the wind turbine generator system is discharged outfrom the air discharging barrel, and foreign matter or rainwater and the like are prevented from entering the device; a supporting frame, a fan motor and a fan impeller are matched so that the high temperature air in the tower of the wind turbine generator system can flow to the air discharging barrel along an air guide opening to be discharged out, and the heat radiating effect can be achieved;and in addition, the effect of replacing air in a liquid discharging pipe and a flow dividing pipe is achieved, the air flowing upwards can be brought away through partial heat of the inner side of the tower of the wind turbine generator system, and the heat radiating effect is strengthened. By means of the heat radiating device, the high temperature air at the upper portion of the tower of the wind turbine generator system can be directly discharged out from the upper portion, the heat inside the tower of the wind turbine generator system can be brought away, the heat radiating efficiency ishigh, the structure is simple, and the overhauling, dismounting and mounting are convenient.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and specifically relates to a cooling device for the inner wall of a wind power generating set. Background technique [0002] Many devices in the wind power generating set will emit a large amount of heat after running for a certain period of time, which will increase the temperature inside the tower of the wind power generating set and affect the normal operation of the equipment. The heat dissipation device of the existing wind power generating set transports the external ambient air to the heating equipment through the air duct, so that the air in the air duct will take away the heat around the heating equipment to achieve the effect of cooling the heating equipment, but the heat generated by the equipment As a result, the hot air can spread to the inside of the tower in a large range, and the heat dissipation efficiency of the existing heat dissipation device is still low.
