Abstract

The utility model relates to a heat exchanger for heat dissipation of a high-power transformer, which comprises a heat dissipation core body arranged around a body of the transformer, and an upper cover plate and a lower cover plate that are respectively fixed at the upper end and the lower end of the heat dissipation core body; the heat exchanger for the heat dissipation of the high-power transformer is characterized in that the heat dissipation core body comprises an outer side shell and an inner side shell, wherein a cavity of the heat dissipation core body is formed by the outer side shell and the inner side shell; the inner side shell of the heat dissipation core body is provided with an internal fin; the outer side shell of the heat dissipation core body is provided with an external fin; and the outer side shell of the heat dissipation core body is also provided with an inlet pipe nozzle and an outlet pipe nozzle. The heat exchanger for the heat dissipation of the high-power transformer is high in heat exchange efficiency, compact in structure, low in manufacturing technique difficulty, low in product cost and small in occupied space.

Description

High-power transformer heat transmission heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, and especially a kind of high-power transformer heat transmission heat exchanger belongs to the transformer radiator field.

Background technology

Transformer capacity needs bigger area of dissipation more greatly; Normally around around fuel tank, install heat exchanger; And the heat exchanger of present most of transformer heat transmissions all is a radiator board-like or the corrugated tube type structure usually; The huge radiation that is of its structure is arranged, and this kind structure is comparatively huge, and cost is high.

For further enhance heat effect, have establish below the transformer cabinet air intake vent, above establish exhaust outlet, through the air channel of going into, form between the exhaust outlet transformer is dispelled the heat thus.But because the device body and the distance between the transformer case inwall of transformer are excessive; Cause air quantity to run off from the transformer outside basically; Can not play due cooling effect; Thereby cause transformer heat radiation bad, influenced the operating efficiency of transformer, make the transformer can only could oepration at full load in certain ambient temperature range.

Because radiating effect can not reach perfect condition, the problem that transformer can't be operated at full capacity also has to adopt and falls the means of appearance, but will influence the actual operating efficiency of transformer so greatly in order to improve.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that exists in the prior art, and the high-power transformer heat transmission heat exchanger of a kind of heat exchange efficiency height, compact conformation is provided.

According to the technical scheme that the utility model provides, said high-power transformer heat transmission heat exchanger comprises heat radiation core body around the device body setting of transformer, is separately fixed at the upper cover plate and the lower cover of said heat radiation core body upper and lower side; Characteristic is: said heat radiation core body comprises outside housing and interior side body, and outside housing and interior side body form the cavity of heat radiation core body, on the interior side body of heat radiation core body, is provided with inner fin, fin outside on the outside housing of heat radiation core body, being provided with.

On the housing of the outside of said heat radiation core body, be provided with inlet nipple and outlet ozzle.

The described high-power transformer heat transmission of the utility model heat exchanger heat exchange efficiency is high, compact conformation, and the manufacturing process difficulty is little, and product cost is low, and it is little to take up room.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with concrete accompanying drawing the utility model is described further.

As shown in the figure: high-power transformer heat transmission heat exchanger comprises upper cover plate 1, outer fin 2, outlet ozzle 3, inner fin 4, lower cover 5, cavity 6, inlet nipple 7 etc.

The utility model comprises around heat radiation core body, the upper cover plate 1 that is separately fixed at said heat radiation core body upper and lower side and the lower cover 5 of the device body setting of transformer; Said heat radiation core body comprises outside housing and interior side body, and outside housing and interior side body form the cavity 6 of the heat radiation core body of negotiable cooling fluid; On the interior side body of heat radiation core body, be provided with inner fin 4, fin 2 outside on the outside housing of heat radiation core body, being provided with;

On the outside housing of heat radiation core body, be provided with inlet nipple 7 and outlet ozzle 3.

The described high-power transformer heat transmission of the utility model heat exchanger utilizes plate-fin structure to make 2 groups 8 plate wing heating panels through vacuum brazing; Through the two groups of square structures that vary in size in argon arc welding welding besieged city; Again upper cover plate is connected two prescription type heating panels with lower cover; Weld radiator turnover oil pipe mouth at last, constitute an airtight square ring-type radiator.The utility model applies to the finned plate heat exchanger design feature in the transformer radiator, improves heat transfer efficiency, makes its structure more compact; Adopt plate-fin structure, increased considerably the area of dissipation of heat exchanger, the heat exchange effect significantly improves, and taking up room relatively also greatly reduces before.
