Abstract
The utility model provides a novel heat-exchange apparatus for a wind-power generation device. The heat-exchange apparatus includes a heat-exchange core used for dissipating heat. The heat-exchange core is fixed at the center of the outer side of the top wall of a machine chamber and is provided with an internal-circular air duct and an external-circular air duct. The internal-circular air duct is provided with an internal-circular draught-fan assembly. The external-circular air duct does not include the draught-fan assembly and dissipates heat through natural wind and the direction of the external-circular air duct is vertical to a rotating circumferential face of the fan blades of a wind power generator. The two ends of the internal-circular air duct are connected through a closed pipe and the pipe is connected with the generator in the machine chamber through the machine chamber. The air-inlet port and the air-outlet port of the internal-circular air duct are used as an internal-circular air-inlet port and an internal-circular air-outlet port. The two ends of the external-circular air duct are used as an external-circular air inlet port and an external-circular air outlet port and heat in the heat-exchange core is taken away by the natural wind. The novel heat-exchange apparatus for the wind power generation device realizes internal and external circular and cross heat exchange through use of the natural wind so that the external-circular draught fan assembly is completely saved and heat dissipation efficiency is greatly improved.
