Transformer heat dissipation device

Abstract

The invention provides a transformer heat dissipation device. A transformer is installed in a transformer cabinet body; a top plate of the transformer cabinet body is provided with exhaust ports, and a bottom plate or side plates of the transformer cabinet body are provided with intake ports. The heat dissipation device comprises air guide pipes which are only arranged around a transformer body; an air outlet and an air inlet are formed in the upper end and the lower end of each air guide pipe respectively; inner transverse partition plates are arranged on the air guide pipes and extend to the transformer body from the inner walls of the air guide pipes; air guide gaps are reserved between the inner transverse partition plates and the transformer body, and the length of the air guide pipes is smaller than or equal to that of the transformer body; external transverse partition plates are arranged between the air guide pipes and the transformer body and separate the air guide pipes from the transformer body; the ends, provided with the air outlets, of the air guide pipes are open. Compared with an existing heat dissipation device, the transformer heat dissipation device is good in heat dissipation effect, simple in structure, high in packaging efficiency and low in packaging cost, overcomes technology biases, is not affected by technological factors and achieves positive and beneficial technical effects.

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...

[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
