A cooling device for a transformer

Abstract

The invention discloses a novel transformer chip heat radiator, and belongs to the technical field of heat radiator devices. The novel transformer chip heat radiator comprises a transformer body, a plurality of vertical main heat dissipating pieces distributed uniformly are welded to the side wall of the transformer body, and a plurality of heat dissipating scale bodies are welded to the verticalmain heat dissipating pieces; a plurality of washing flow guiding holes distributed uniformly are formed in the heat dissipating scale bodies and located at the ends close to the vertical main heat dissipating pieces, and thermal insulating layers are fixedly connected to the upper surfaces of the heat dissipating scale bodies and coated with reflective layers; the radiator can improve the heat dissipating point height of the transformer to increase oil flow falling, it can be easily ensured that oil flow is smooth, and heat transferring and heat dissipating are quick, through the vertical main heat dissipating pieces of bending structures and the heat dissipating scale bodies, the heat dissipating effect can be greatly improved, when sunniness is powerful, temperature rising which is caused by sunlight and occurs on the transformer body can be greatly reduced, and the transformer cannot be easily destroyed due to high temperature.

Description

technical field [0001] The present invention relates to the technical field of heat sinks, and more specifically, to a transformer chip heat sink. Background technique [0002] When the transformer is running, it will generate heat. This heat comes from two aspects. One is the iron loss, which is the heat generated by the eddy current loss in the transformer core. The other is the heat generated by the load current flowing through the transformer winding. The square is proportional, the heat must be dissipated in time, otherwise the transformer will be damaged, so the transformer needs to be installed with a radiator. When selecting a traditional radiator according to the capacity of the transformer, it can only increase the number of radiators and widen the radiator. The heat dissipation point is low and cannot Effective heat dissipation, bulky after widening, resulting in increased transportation costs.

[0002] When the transformer is running, it will generate heat. This heat comes from two aspects. One is the iron loss, which is the heat generated by the loss of eddy current in the transformer core. The other is the heat generated by the load current flowing through the transformer winding. The square is proportional, the heat must be dissipated in time, otherwise the transformer will be damaged, so the transformer needs to be installed with a radiator. When selecting a traditional radiator according to the capacity of the transformer, it can only increase the number of radiators and widen the radiator. The heat dissipation point is low and cannot Effective heat dissipation, bulky after widening, resulting in increased transportation costs

[0003] The cooling effect of the finned radiator directly affects the thermal aging progress of the transformer oil in operation and the solid insulating material. Through analysis and demonstration, the selection of the specification and arrangement of the finned radiator has a great impact on the reliable operation of the transformer. The disadvantages of the existing technology are as follows: , the heat dissipation point is low, and the horizontal dimension is wide, resulting in poor oil flow of the transformer and poor heat dissipation effect, and it will carry a lot of heat when it is exposed to direct sunlight, which is easy to cause the temperature of the transformer to rise and make the transformer easy to be damaged.
