Power transformer with active heat dissipation function

Abstract

The invention discloses a power transformer with an active heat dissipation function, and relates to the field of electrical devices. The power transformer comprises a case, a case door, a case cover, a coil iron core module, four ventilation pipes, heat pipes, a heat dissipation assembly and a heat conduction block; the four ventilation pipes are symmetrically arranged at the positions close to the four corners of the case and are fixedly connected into the case through a rack; the two ventilation pipes located at the front side of a coil iron core and the two ventilation pipes located at the rear side of the coil iron core are connected through a heat dissipation assembly, and the heat conduction blocks and the heat dissipation assemblies are connected together through the heat pipes, so that the heat conduction effect can be achieved. Telescopic heat conduction mechanisms capable of adjusting the positions of the heat conduction plates according to the temperature change are further mounted at the front and rear sides of the heat conduction blocks. According to the present invention, the heat in the case is discharged in time in an active heat dissipation manner; by adopting a heat pipe heat dissipation technology, and compared with the traditional cooling fin heat dissipation, the heat dissipation efficiency is remarkably improved; and by matching with the heat dissipation assemblies, a better heat dissipation effect can be obtained.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to an active heat dissipation power transformer. Background technique [0002] As a general-purpose equipment, transformers are widely used in the power field. They are divided into two types: oil-immersed and dry-type. For dry-type transformers, the heat dissipation method is mostly natural heat dissipation through the metal shell, and some use internal fans for auxiliary heat dissipation. However, since the fan can only be installed on the periphery of the coil cores, the heat between adjacent coil cores cannot be effectively dissipated, and the overall heat dissipation effect is not ideal, especially when the external ambient temperature is relatively high. Contents of the invention [0003] The object of the present invention is to provide an active heat dissipation power transformer to solve the above-mentioned defects caused by the prior art.

[0002] As a general equipment, transformers are widely used in the field of electric power. They are divided into two types: oil-immersed and dry-type. The shell dissipates heat naturally, and some use a fan inside for auxiliary heat dissipation, but since the fan can only be installed on the periphery of the coil core, the heat between adjacent coil cores is often not effectively dissipated, and the overall heat dissipation effect Not ideal, especially if the outside ambient temperature is high
