Problems solved by technology

The current wind turbines are generally cooled by air cooling or liquid cooling. Among them, the air cooling method requires fans, etc., and the liquid cooling method requires fans and pumps. Fans and pumps are prone to failure during long-term use, while wind power generation The cooling equipment of the wind turbine is installed on the top of the tower. The failure of the cooling equipment is not only difficult to repair and replace, but also difficult to be found in time, which may easily affect the normal operation of the wind turbine.

specific Embodiment 1

[0035] Specific embodiment one: as figure 1 As shown, an evaporative cooling device applied to a wind power generator includes a radiator 1 and a cold plate 3 . The radiator is installed on the outside of the nacelle shell 2 of the wind turbine, and the radiator includes a radiator shell, an air storage chamber 1.1 located at the top of the radiator shell, a liquid collection chamber 1.2 located at the bottom of the radiator shell, and several connected air storage chambers. 1.3 Heat dissipation channel of chamber and liquid collection chamber. The cold plate is fixed on the heat generating device of the wind power generator, and is used for cooling the heat generating device. The cold plate 3 includes a cooling chamber arranged in the cold plate and a steam chamber 3.1 located on the top of the cold plate. The steam chamber communicates with the cooling chamber. The cooling cavity is filled with refrigerant. The height of the radiator is higher than that of the cold plate...

specific Embodiment 2

[0043] Specific embodiment two: the specific structure of this embodiment is with reference to specific embodiment one, and its difference is:

[0044] Such as image 3 As shown, there are multiple cold plates 3 in this embodiment, for example, there are 2 or 3 or 4 or more cold plates, and the number of cold plates is determined according to specific heat dissipation devices. There are 3 cold plates shown in the picture.

[0045] In this embodiment, a plurality of partitions 1.0 are provided inside the radiator housing, and the partitions divide the inner cavity of the radiator housing into several heat dissipation cavities distributed side by side. The cooling cavity corresponds to the cold plate one by one. Each cooling cavity includes an air storage chamber at the top of the radiator housing, a liquid collection chamber at the bottom of the radiator housing, and a plurality of cooling passages connecting the air storage chamber and the liquid collection chamber. Each co...

specific Embodiment 3

[0046] Specific embodiment three: the specific structure of this embodiment is with reference to specific embodiment one, and its difference is:

[0047] The steam pipeline in this embodiment is provided with a pump. In this way, the pump can be used to force the refrigerant (including gaseous and liquid refrigerant) to circulate in the evaporative cooling equipment to improve the cooling effect of the evaporative cooling equipment; Compared, it still eliminates the fan, so it can still reduce the possibility that the cooling equipment is prone to failure.

Abstract

The invention discloses an evaporative cooling device applied to a wind driven generator, and aims to provide the evaporative cooling device which can effectively solve the problem that the normal work of the wind driven generator is influenced due to the fact that the cooling device of the current wind driven generator is easy to fail under the condition that the cooling effect is not influenced.The evaporative cooling device comprises a radiator which is installed at the outer side of a cabin shell of the wind driven generator and comprises a radiator shell body, an air storage chamber located at the top of the radiator shell body, a liquid collecting chamber located at the bottom of the radiator shell body and a plurality of radiating channels connected with the air storage chamber andthe liquid collecting chamber; a cold plate which is used for cooling the heating device, comprises a cooling cavity formed in the cold plate and a steam cavity located at the top of the cold plate,wherein the steam cavity is communicated with the cooling cavity, and the cooling cavity is filled with a refrigerant. The radiator is higher than the cold plate, the gas storage chamber is connectedwith the steam cavity through a steam pipeline, and the liquid collection chamber is connected with the liquid storage cavity through a liquid return pipeline.

Description

technical field [0001] The invention relates to a cooling device, in particular to an evaporative cooling device applied to a wind power generator. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. A wind power generator generally includes: a tower, a wind wheel, a generator, a gear box, a cooling device, a controller, etc., wherein the generator, the controller, the gear box, etc. are arranged in the nacelle. During the operation of the wind turbine, the heat-generating device (such as the generator) of the wind-driven generator will generate a large amount of heat, so cooling equipment is required for cooling to ensure the normal operation of the heat-generating device. The current wind turbines are generally cooled by air cooling or liquid cooling. Among them, the air cooling method requires fans, etc., and the liquid cooling method requ...
