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...

Embodiment Construction

[0051] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0052] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0053] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and should not be construed as limiting.

[0054] In the present invention, unless otherwise specified, the quantifiers "a" and "an" do not exclude the scen...
