Description

Transformer natural cooling high-efficiency radiator

Technical field

The utility model relates to a kind of radiator more particularly to a kind of fluid radiator, transformer natural cooling height Imitate radiator.

Background technique

The natural cooling of existing transformer is mainly gilled radiator, using irony plate, after punching press, is welded, Product is heavy, and material heat dissipation effect characteristic is poor, and without inner fin and outer fin, therefore heat exchange area very little in unit, heat dissipation are imitated Fruit is poor, as a result often sufficiently bulky just to can overcome the disadvantages that the insufficient defect of heat dissipation, volume this state bigger than normal lead to transformer oil Usage amount also increases；In order to solve the slow defect that radiates, it is scattered to improve that Ye You manufacturer increases radiator fan outside transformer Thermal velocity, but this equally also increases use cost, therefore it is badly in need of a kind of small in size, rapid heat dissipation goes out, is at low cost.

Utility model content

In view of this, the technical problem to be solved by the utility model is to providing a kind of knot in view of the deficiencies of the prior art Structure is simple, perfect heat-dissipating, outside small in size, at low cost use the transformer nature in binary channels air radiating airflow channel Cooling high-efficiency radiator.

In order to reach said effect, what the utility model adopts the following technical solution to realize:

A kind of transformer natural cooling high-efficiency radiator, including radiator casing and radiator body, the radiator The upper end of shell is equipped with hot oil entrance, and the lower end of the radiator casing is exported equipped with cold oil, and the radiator body is set to institute It states in radiator casing body, the radiator body is equipped with the oily channel of several streams, and the two sides for flowing oily channel are respectively welded vertical Straight outer fin and horizontal outer fin.

Preferably, the oily channel of the stream includes runner fin and runner plate, the runner fin seal is welded in described Runner plate.

Preferably, the runner fin is in rectangle channel-shaped.Rectangular configuration design had both increased runner fin as heat dissipation The heat dissipation area of the inner fin of device, simultaneously because rectangular configuration, the linear design of runner fin to the resistance of the flowing of oil very It is small.

Preferably, the upper and lower section for flowing oily channel be it is horizontally disposed, the middle section in stream oil channel is vertically arranged, described The upper and lower section difference sealing welding in oily channel is flowed in the middle section for flowing oily channel.Upper section level stream of the hot oil from the oily channel of stream The lower section level that then cold oil that vertical component after entering into middle section cools flows into oily channel is flowed into radiator casing Cold oil outlet and from cold oil export flow out.

Preferably, the vertical outer fin is in wave channel-shaped.Wave channel-shaped fin increases the heat dissipation of vertical outer fin Area.

Preferably, the outer fin of level is in wave channel-shaped.Wave channel-shaped fin increases the heat dissipation of the outer fin of level Area.

Preferably, the radiator body is aluminum alloy material.Aluminium alloy material mass-energy reduces the weight of radiator, carries It is convenient and at low cost.

As shown from the above technical solution, the beneficial effects of the utility model are:

Compared with prior art, structure is simple, perfect heat-dissipating, small in size, at low cost；Outside is using vertical outer fin and water The binary channels air heat transmission gas circulation of flat outer fin, which can increase heat dissipation area and flow through fin outside level using natural wind, to be added The effect of quickly cooling but, significant effect at low cost.

Specific embodiment

In order to enable those skilled in the art to be further understood that the feature and technology contents of the utility model, please refer to Under the detailed description and accompanying drawings in relation to the utility model.

Please refer to a kind of transformer natural cooling high-efficiency radiator shown in Fig. 1 to Fig. 7, including radiator casing 1 and aluminium Alloy heat-sink device ontology 2, the upper end of radiator casing 1 are equipped with hot oil entrance 3, and the lower end of radiator casing 1 is exported equipped with cold oil 4, radiator body 2 is set in radiator casing 1, and radiator body 2 is equipped with the oily channel 21 of several streams, flows oily channel 21 Vertical outer fin 22 and horizontal outer fin 23 is respectively welded in two sides；Flowing oily channel 21 includes runner fin 211 and runner plate, runner 211 sealing welding of fin is in the runner plate.

As Figure 2-3, the hot oil in oil tank of transformer 5, which flows into enter from hot oil entrance 3, flows oily channel upper section level stream The lower section level for entering the then oily channel of cold oil inflow stream that middle section vertical component cools after entering is flowed into radiator casing 1 It is simultaneously flowed out from cold oil outlet 4 cold oil outlet 4；Hot oil transfers heat to vertical outer fin 22 and level by runner fin 211 Outer fin 23, cools rapidly；Natural wind horizontal direction enters the outer fin 23 of level and takes away hot oil heat；Wave channel-shaped is hung down Hot gas after being heated in the wave channel of straight outer fin 22 by hot oil flows out vertical outer fin 22 vertically upward takes away heat；Hot oil quilt Density becomes larger after radiator is cooling, flows down into oil tank of transformer 5, and cold oil is again introduced into radiator after being heated, and forms heat The continuous circulating cooling of convection current, oily flowing do not need oil pump driving, have saved very big cost.

The foregoing is merely the preferable possible embodiments of the utility model, not to limit to the patent model of the utility model It encloses, thus it is all with the variation of equivalent structure made by the utility model specification and accompanying drawing content, it is practical new to be similarly included in this In the range of type.
