Semi-open high-power equipment cooling system and cooling method

Abstract

The invention relates to the technical field of cooling systems, and provides a semi-open high-power equipment cooling system and method. The system comprises a semi-open high-power equipment structure, semi-open high-power equipment, inner radiators, inner radiator fans and a pipeline connection cooling system. The cooling requirements of the semi-open high-power equipment and a closed environment can be met at the same time, so that the total cost of the cooling system is greatly reduced. The convection heat transfer of the outer wall of the semi-open high-power equipment structure can be enhanced by 5-10 kW, and therefore self power consumption of the cooling system is remarkably reduced. A cooling backpack is omitted, and the plurality of inner radiators are arranged below the semi-open high-power equipment, so that the size limitation pressure of the high-power equipment in the layout in a closed environment is effectively relieved. Compared with single-side ventilation, double-side ventilation is adopted, so that local hot spots of a heating element are effectively reduced.

Description

technical field [0001] The present invention generally relates to the technical field of cooling systems. Specifically, the present invention relates to a semi-open high-power equipment cooling system and method. Background technique [0002] For high-power equipment arranged in a closed environment, its supporting cooling system is a very important part. Taking the offshore wind turbine as an example, the high-power equipment in the offshore wind turbine can be, for example, a fan transformer, which is arranged in the wind tower, and its heating element is mainly the transformer winding. [0003] Such as figure 2 As shown, the wind turbine transformer in the prior art usually adopts a closed water-cooled dry-type transformer, in which the cooling of the transformer winding 201 is realized through the cooling backpack 203 arranged on the side of the wind turbine transformer. However, due to the use of a closed water-cooled dry-type transformer, the air inside the fan towe...

AI Technical Summary

Problems solved by technology

In this way, since the wind turbine transformer and the wind tower environment need to be equipped with independent cooling equipment, this makes the total cost of the cooling system high and the self-consumption of the offshore wind turbine also greatly increases

Moreover, since the cooling backpack 203 usually needs to be arranged on the side of the fan transformer, this makes the circumferential dimension of the fan transformer larger, which is not conducive to building the fan transformer into the fan tower.

In addition, since the cooling backpack is only ventilated on one side of the cooling backpack, its ventilation flow balance is poor, which will cause local temperature rise hot spots on the leeward side of the transformer winding 201
