Multifunctional radiator for high-efficiency transformer

Abstract

The present invention relates to a multifunctional radiator for a high-efficiency transformer. The multifunctional radiator comprises an upper oil collecting pipe, a lower oil collecting pipe and a heat dissipation mechanism which is located between the upper oil collecting pipe and the lower oil collecting pipe and communicates with the upper oil collecting pipe and the lower oil collecting pipe,the heat dissipation mechanism comprises a plurality of heat dissipation pipes which are arranged in a linear array, the outer edge contours of the heat dissipation pipes are of tooth-shaped curved surface structures, and heat dissipation fins are arranged outside the heat dissipation pipes; and a sun shade is arranged outside the heat dissipation pipes in a covering mode, the sun shade is connected with the heat dissipation pipes through a plurality of connecting plates located inside the sun shade, the connecting plates are arranged on the sun shade at intervals, and the connecting plates and the outer surface of the heat dissipation pipes form a plurality of airflow channels. The outer surface of the sun shade is coated with a heat insulation coating; and the upper and lower ends of the radiator are respectively provided with an air outlet and an air inlet. The transformer radiator is good in heat exchange effect, reduces light irradiation and can be widely applied to the technicalfield of transformer radiators.

Description

technical field [0001] The invention relates to the technical field of radiators for power transformers, in particular to a multifunctional radiator for powerful transformers. Background technique [0002] Power transformers play an important role in the transmission process of power resources. Heat dissipation is the most important problem for transformers to solve, and the heat dissipation effect depends on the transformer radiator. At present, the transformers on the market mostly use oil-immersed transformers, and the chip radiator is the main cooling and heat dissipation equipment. More than 80% of the small and medium-sized transformers adopt the cooling method of natural oil circulation + natural air cooling (ie ONAN). It does not require a fan, has no fan noise, and is easy to maintain. The cooling efficiency of this finned radiator is low, the equipment is large in size, it needs to be painted for corrosion protection, and the environmental pollution is serious. Wi...

Problems solved by technology

The cooling efficiency of this finned radiator is low, the equipment is large in size, it needs to be painted for corrosion protection, and the environmental pollution is serious. With the enhancement of people's environmental awareness and higher requirements for noise pollution, coupled with the mandatory Heat is easy to cause oil flow electrification and other reasons, the development of new ONAN cooling radiator is an urgent problem to be solved

For transformers installed outdoors, the sun directly shines on the radiator body, and the surface temperature of the body is as high as 1.5 to 2 times that of the air temperature. Work, accelerate the aging of transformer oil, cause insulation material failure, cause internal short circuit combustion and other electrical failures
