A cooling device for a transformer

Abstract

The invention discloses a transformer cooling device. Transformer bodies are mounted in a cabinet, the cabinet comprises a top plate, a bottom plate and side plates on four sides, the side plates areof double-layer structures, and a gap is reserved between each inner plate body and teach outer plate body; a plurality of ventilation grills A is arranged on each inner plate body from top to bottom;a plurality of ventilation grills B is arranged on each outer plate body from top to bottom; an air outlet is arranged in the top plate of the cabinet; an air intake is arranged in the bottom plate of the cabinet; a cooling frame is arranged between two neighboring transformer bodies; guide ducts are arranged on the cooling frame. The guide ducts are arranged around the transformer bodies, flow of wind is accelerated, and temperature of a transformer is forcefully lowered.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device applied to a transformer. Background technique [0002] In the prior art, the heat dissipation method of the transformer is generally to open cooling holes on the cabinet body of the transformer, so as to dissipate heat through natural wind. As a result, the transformer is dissipated through the air duct formed between the air inlet and the exhaust port. However, due to the excessive distance between the transformer body and the inner wall of the transformer cabinet, part of the air volume is basically lost from the outside far away from the transformer body, which cannot be achieved. As a result, the heat dissipation of the transformer is not good, which affects the working efficiency of the transformer, so that the transformer can only operate at full load within a certain ambient temperature range. [0003] In order to improve the problem that the transfo...

Problems solved by technology

[0002]In the prior art, the heat dissipation method of the transformer is generally to open heat dissipation holes on the cabinet body of the transformer, so as to dissipate heat through natural wind. In order to further enhance the heat dissipation effect, there are An air inlet is provided at the bottom of the cabinet, and an air exhaust outlet is arranged at the top, so that the transformer can be dissipated through the air channel formed between the air inlet and the exhaust outlet. However, because the distance between the transformer body and the inner wall of the transformer cabinet is too large, As a result, part of the air volume is basically lost from the outside away from the transformer body, which cannot play the role of cooling, which leads to poor heat dissipation of the transformer and affects the working efficiency of the transformer, so that the transformer can only be fully loaded within a certain ambient temperature range run

[0003] In order to improve the problem that the transformer cannot work at full load due to the fact that the heat dissipation effect cannot reach the ideal state, there are also means of reducing the capacity, but this greatly affects the actual operating efficiency of the transformer
