Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for a bottom platform of a wind power tower. Background Art

[0002] The bottom platform of the wind turbine tower, where electrical components such as the frequency converter, auxiliary transformer, and main control cabinet are located, will accumulate heat generated by these components. If the heat cannot be discharged in time, it will affect the life of the electrical components and the stability of operation. Therefore, the bottom platform of the wind turbine tower needs to be cooled. Currently, there are several ways to cool the bottom platform of the wind turbine tower:

[0003] Method 1: Installing axial flow fans on the side walls of the tower solves the heat dissipation problem of the platform at the bottom of the tower. However, the use of traditional axial flow fans for ventilation and heat dissipation has several inevitable problems. First, electrical components need to be protected from dust and sand during operation. Axial flow fans must be installed with dust screens, which will affect the ventilation effect of the axial flow fans and require regular cleaning of dust. Second, in specific environments such as the Gobi Desert, the ambient temperature outside the tower is also relatively high. When high-temperature air enters the space at the bottom of the tower, the heat dissipation effect is greatly reduced. Third, the bottom of the tower is an important load-bearing component of the wind turbine. Installing axial flow fans requires openings in the side walls of the tower, which affects the safety of the tower. The reinforcement structure around the openings of the axial flow fans will also increase the processing and manufacturing costs of the tower.

[0004] Method 2: Use an above-ground water-cooled heat exchange system to dissipate heat from the tower base platform. Although this method can solve the dust prevention problem and partially resolve the problem of opening holes in the tower wall, it still cannot specifically address the high ambient temperature of the wind farm.

[0005] Method 3: Using an air conditioning refrigeration system. While this effectively solves the ventilation and heat dissipation issues associated with axial fans, it is expensive to operate and requires increased equipment security costs. Therefore, the technical problem to be solved by this invention is how to provide a solution with lower operating and security costs to solve the heat dissipation problem at the base platform of the wind turbine tower.

[0006] Application number CN202320360815.5 in the prior art provides a heat dissipation device for the bottom platform of a wind turbine tower. The electrical equipment compartment inside the tower is provided with electrical equipment that is not in contact with the tower wall. The electrical equipment is installed on the bottom platform of the wind turbine tower. The wind turbine tower includes a concrete foundation at the part below the ground. The heat dissipation device includes: an energy-absorbing tube arranged in the electrical equipment compartment inside the tower; a bottom space is provided in the concrete foundation, the bottom space has water, and some heat dissipation tubes are arranged below the water surface; or / and some heat dissipation tubes that extend into the concrete foundation and are in direct contact with the concrete foundation; the energy-absorbing tube and the heat dissipation tube are connected by a pipeline to form a loop, the loop has a heat transfer fluid, and the loop is provided with a drive motor that drives the heat transfer fluid to flow in the loop. The use of this application can achieve a solution with lower operating costs and security costs to solve the heat dissipation problem of the bottom platform of the wind turbine tower. The above-mentioned heat dissipation device at the bottom platform of the wind turbine tower absorbs heat through the energy-absorbing tube and then inputs the heat into the concrete foundation. However, this method will reduce the strength of the concrete foundation, thereby affecting the safety of the entire wind turbine equipment. Therefore, it is necessary to improve it to address the above problems. Utility Model Content
