Spliced transformer radiator

Abstract

The invention discloses a spliced transformer radiator. Thespliced transformer radiator comprises an oil tank, a fixing pipe, an air cooling heat dissipation device and a water cooling heat dissipation device; supporting legs are fixedly welded to the bottom of the oil tank; an air guide box fixedly installed on the supporting legs is arranged below the oil tank; a driving motor is fixedly installed at the top of the air guide box; and the lower end of the driving motor penetrates through the air guide box to be connected with centrifugal fan blades; the centrifugal fan blades are suspended inthe air guide box; and an air inlet is formed in the bottom of the air guide box. According to the spliced transformer radiator, the centrifugal fan blades and the air guide box are adopted; the airguide box is installed below the oil tank; the driving motor drives the centrifugal fan blades to rotate; the centrifugal fan blades extract air through the air inlet and exhaust the air through an air outlet; airflow exhausted through the air outlet passes through the outer sides of radiating fins and takes away heat; when the centrifugal fan blades stop operating, natural wind is blown into gapsamong the radiating fins; and therefore, obstruction caused by the centrifugal fan blades is avoided, and the natural radiating effect of the radiator is improved.

Description

technical field [0001] The invention relates to the technical field of transformer radiators, in particular to a spliced ​​transformer radiator. Background technique [0002] Transformers will inevitably generate waste heat during operation, and in order to avoid insulation damage caused by the accumulation of waste heat, a radiator is required for heat dissipation. [0003] The existing radiator is usually directly welded on the fuel tank, so that there are many welding points between the radiator and the fuel tank. Once there is a problem in the welding process, it is very easy to cause the transformer to be completely scrapped, which greatly increases the difficulty of production and processing. Now Some radiators only rely on steel heat dissipation pipes to contact air for heat dissipation, but the heat conduction efficiency and heat dissipation efficiency of steel heat dissipation pipes are not high, which leads to the overall efficiency of the radiator is not high, it ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a spliced ​​transformer radiator to solve the problem that the existing radiators proposed in the above background technology are usually directly welded on the oil tank, so that there are many welding points between the radiator and the oil tank. If there is a problem, it is easy to cause the transformer to be completely scrapped, which greatly increases the difficulty of production and processing. The existing radiator only relies on the steel heat dissipation pipe to contact the air for heat dissipation, but the heat conduction efficiency and heat dissipation efficiency of the steel heat dissipation pipe Both are not high, which leads to the problem that the overall efficiency of the radiator is not high, and it is not practical enough to use
