Radiating device of wind power generation water cooling system and water cooling system

Abstract

The invention discloses a radiating device of a wind power generation water cooling system used for radiating cooling liquid in a liquid collection box of the water cooling system arranged in an engine room cover, wherein the radiating device comprises a plurality of heat pipes, heat absorption segments of the heat pipes are arranged in the liquid collection box, and heat release segments of the heat pipes are arranged at the outside of the engine room cover. The invention further discloses the wind power generation water cooling system comprising the radiating device, wherein the radiating device disclosed by the invention indirectly cools the cooling liquid of the cooling system substantially by means of the heat exchange property of the heat pipes and natural gas with excellent wind field without utilizing cooling fans or plate heat exchangers, thereby avoiding the energy consumption of the fans and avoiding the high braze welding technology of the plate heat exchangers; besides, the radiating device can fully utilize the excellent natural wind in a wind field to cool and radiate the cooling liquid so as to exert the energy saving effect.

Description

technical field [0001] The invention relates to the technical field of water cooling for wind power generation, in particular to a cooling device for a water cooling system for wind power generation and a water cooling system including the cooling device. Background technique [0002] For the existing wind turbine water cooling system, the cooling and heat dissipation device of the coolant is mostly a combination of a plate heat exchanger and a fan, and the fan is installed on the plate heat exchanger to perform forced convection heat dissipation on the coolant, or the plate heat exchanger is placed on the The roof of the nacelle is naturally cooled by the natural wind from the wind field. The former fan consumes energy, increases equipment, and has a complex structure. The latter uses natural wind. Due to the narrow channel size and large wind resistance, when the wind field wind speed is about 10m / s, The natural wind speed that can pass through the cooling air duct is only...

The former fan consumes energy, increases equipment, and has a complex structure. The latter uses natural wind. Due to the narrow channel size and large wind resistance, when the wind field wind speed is about 10m / s, The natural wind speed that can pass through the cooling air duct is only 2m / s-3m / s, and the plate heat exchanger has higher requirements for brazing technology
