Energy-saving cooling system of wind generating set frequency converter

Abstract

The invention provides an energy-saving cooling system of a wind generating set frequency converter. The energy-saving cooling system comprises the frequency converter, a pipeline pump, a cooling liquid pipe, a hot liquid divider, a cold liquid divider, a high-level liquid collection box and two sets of radiating pipes, wherein the frequency converter, the pipeline pump and the cooling liquid pipe are located in a tower; the pipeline pump is connected with a heating component in the frequency converter through the cooling liquid pipe; one end of the hot liquid divider is connected with the high-level liquid collection box through the first set of radiating pipes; the other end of the hot liquid divider is connected with the heating component inside the frequency converter through the cooling liquid pipe; one end of the cold liquid divider is connected with the pipeline pump through the cooling liquid pipe; the other end of the cold liquid divider is connected with the high-level liquid collection box through the second set of air cooling radiating pipes; the top face of a cabin on the top of the tower is provided with an exhaust skylight of which an opening is back on to a wind wheel. According to the energy-saving cooling system, natural wind makes full contact with the surfaces of the radiating pipes inside the tower and takes heat energy away, cooling liquid with heat energy of the heating component of the frequency converter inside the radiating pipes is cooled rapidly, the good cooling effect is achieved without an air blower, energy sources are saved greatly, and environment noise of a whole wind power plant is lowered greatly.

Description

technical field [0001] The invention relates to a wind power generation technology, in particular to a cooling and cooling system in the wind power generation technology, and more particularly to an energy-saving cooling and cooling system for a frequency converter of a wind power generating set. Background technique [0002] As an emerging energy with great potential, wind power has become the most promising emerging energy industry for commercial development due to its renewable, pollution-free, and low-cost characteristics. It has also been widely used around the world. Wind power may become The world's most important alternative energy in the future. [0003] A large wind turbine consists of two parts: the mechanical part and the electrical part. The mechanical part includes the wind wheel, yaw system, pitch system and brake system. Its function is to drive the generator to rotate by the wind and convert wind energy into mechanical energy; Parts include generators, freq...

Problems solved by technology

A wind turbine with a stand-alone capacity of 2000 kilowatts requires two 4 kilowatt blowers to blow air to its radiator 24 hours a day to achieve the corresponding cooling effect. This kind of inverter cooling system not only consumes a lot of energy , and produce very loud environmental noises. In addition, the radiators and blowers installed outside the tower are vulnerable to environmental influences and man-made damage, requiring a large maintenance fee. These not only increase the cost of wind power generation, but also affect The efficiency of wind power
