Novel transformer heat dissipation box

Abstract

The invention discloses a novel transformer heat dissipation box which comprises a box body, a transformer is sleeved with the box body, an annular cooling cavity is formed between the inner wall of the box body and the outer wall of the transformer, and an annular water collection platform communicated with the annular cooling cavity is formed at the top of the box body. Annular water storage cavities communicated with the annular cooling cavity are formed in the middle of the inner wall of the box body and in the position close to the bottom of the box body respectively, a plurality of heat dissipation sets are evenly distributed on the outer wall of each annular water storage cavity in the annular direction, and each heat dissipation set comprises three heat dissipation rods formed by protruding the outer wall of the corresponding annular water storage cavity upwards and downwards respectively. The heat dissipation box has the advantages that the heat dissipation fins are structurally designed to be formed in the mode that the outer wall of the annular water storage cavity protrudes upwards and downwards, efficient heat dissipation is achieved, and the occupied area of the heat dissipation box is greatly reduced while the heat dissipation effect is not reduced through the structure.

Description

technical field [0001] The present application relates to the field of transformers, in particular to a novel transformer cooling box. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). [0003] The transformer will generate a lot of heat when it is worki...
