AI Technical Summary

Technical Problem

In order to accommodate the three-dimensional coiled core, the existing transformer oil tank has a large volume and size, a large area and difficult to dissipate heat.

Method used

A transformer oil tank including a box and a chip radiator is designed. The box forms a hexagonal structure. A spaced-mounted chip radiator is installed on the outside of the long box wall. The chip radiator includes a spaced-mounted heat sink and fins, and the fins are connected to adjacent heat sinks to enhance the heat dissipation effect.

Benefits of technology

Through a compact hexagonal structure and a chip radiator that is close to the long box wall, the space occupation of the transformer fuel tank is reduced, the heat dissipation effect is improved, and the problems of large footprints and difficult heat dissipation are solved.

Abstract

The utility model discloses a transformer oil tank and transformer relates to transformer technical field, the transformer oil tank includes box body and plate radiator, box body includes box cover, side wall and base, box cover and base are connected to the top and bottom of side wall respectively, side wall includes three long box wall and three short box wall, the plate radiator includes plate radiator, the plate radiator includes plate radiator. The three long box walls and the three short box walls are alternately connected to define an oil storage space with a hexagonal cross section, and the box cover and the base are both in a hexagon shape matched with the shape of the cross section of the oil storage space. The outer side of each long box wall is provided with a plurality of finned radiators which are arranged at intervals, each finned radiator comprises a plurality of radiating fins which are arranged at intervals, and a fin is connected between any two adjacent radiating fins. The finned radiators are tightly attached to the long tank wall, the space of the transformer oil tank can be reduced as much as possible, and the occupied area is saved. The finned radiators on the three long box walls are far away from one another, mutual interference among the multiple finned radiators is avoided, and the heat dissipation effect is good.
