Abstract

The utility model relates to an improved radiator for a transformer, which comprises the components such as a bottom seat, a transformer main body, etc. The bottom seat is formed by that L-shaped sheets are locked opposite to each other, and the transformer main body is composed of a coil cladding component and silicon steel sheets which are ranged by being mutually stacked. An inverted-L-shaped heat-radiating guide plate is matched and inserted in a clearance on one side of the silicon steel sheets and the coil cladding component, the inner part of the heat-radiating guide plate is hollow, and heat-conducting fluid is filled in the inner part of the heat-radiating guide plate. Heat radiating squamae which are annularly ranged are arranged on an outer ring of the horizontal section of a plate surface on the outer top of the heat-radiating guide plate. High heat quantity of the inner part of a transformer is rapidly guided and emitted to outside by the heat-conducting fluid, and the heat-conducting fluid cooperates with the structure of the heat radiating squamae arranged on the surface of the outer margin of the heat-radiating guide plate to make heat radiating area increased oppositely, so the effect of rapid cooling can be achieved, the service life of the entire transformer can be properly prolonged, and the service power of the entire transformer is improved.

Description

Heat dissipating device of transformer

The utility model relates to the transformer in a kind of electricity essential electronic element field, particularly relate to a kind of heat radiation when aiming at transformer and using and design, insert group by a heat radiation guide plate, the serviceability temperature of whole transformer can be dispelled the heat rapidly, and guarantee the effectively lasting use of its internal insulator, and can reach the heat dissipating device of transformer of the improvement radiator structure of the effect that improves service efficiency and prolong service life.

The design of general traditional transformer, mostly be designed to as Fig. 4, shown in Figure 5, its whole structure installing, mainly do not arrange folded group silica steel disc 22 together mutually by there being several pieces, cooperate the bottom to be provided with 20 dresses of base of forming by two L shaped 21 mutual clampings, then cooperate in the outside of silicon steel sheet 22 and to be provided with coil 23 and to give around coating, and also be provided with two L shaped 24 relative lockers at the top, the common structural entity of forming a complete transformer, and because transformer can produce high temperature in use, be the raising and the prolongation of trying to achieve its service efficiency, so it must be seated in the better position of ventilation, cooperate suitable ventilation to make its high temperature can obtain suitable cooling, to reach the instructions for use of safety and persistent high efficiency rate.

Yet assembling position for general transformer, because it mostly must be seated in the higher place of safety, its entire heat dissipation is also because the ventilation effect of eminence is preferable, and the heat radiation function of the actual use of raising transformer that can be suitable, though but the use of whole transformer can be strengthened by ventilation, but mainly generating heat for it is the space segment that the silicon steel sheet 22 in inside is covered, make inner hot gas can't effectivelyly distribute or be directed to always the outside relatively, and the also general just transformer temperature outside of this point should have the cause of preferable ventilation cooling, make its surface on temperature, can obtain the use situation of a lower temperature, yet its inner high temperature but can't obtain more suitable or appropriate heat radiation always to be improved, and this point also is the defective that general transformer is felt puzzlement in the use most.

Because the drawback of above-mentioned traditional product, the design people is based on abundant practical experience and professional knowledge, through constantly studying, design, and after studying sample repeatedly and improving, creates the utility model finally.

Main purpose of the present utility model is, overcome the deficiencies in the prior art, and provide a kind of structure improved heat dissipating device of transformer, it is provided with is inserted into the heat radiation guide plate that transformer coats coil and silicon steel sheet inside, the fluid that heat absorption is arranged according to guide plate hollow inner filling, by flowing of fluid, can be rapidly the heat of inside be dispersed into the outside, the structure setting of set heat radiation scale on the matching board face, can increase considerably area of dissipation, effectively reduce the heating temp of whole transformer, further can reach proper extension service life and increase fail safe, and have the effect that improves power.

The purpose of this utility model is realized by following technical scheme.A kind of structure improved heat dissipating device of transformer includes a base of being dressed up by L shaped relative lock and reaches the members of being made up of the silicon steel sheet and the coil coating of folded arrangement mutually such as transformer body; It is characterized in that: the side clearance that this silicon steel sheet and coil coat, cooperate insert group to be provided with one and be down L shaped heat radiation guide plate, the inside of this heat radiation guide plate is designed to a hollow form, and its inner filling has heat-conducting fluid.

The purpose of this utility model can also further realize by following technical measures.Aforesaid heat dissipating device of transformer, the plate face outer shroud of wherein said its outer top, horizontal section of heat radiation guide plate is provided with annular heat radiation scale.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, the utility model is the heat dissipating device of transformer of the new-type heat dissipation improved structure of heat dissipation design when aiming at the transformer use, its mainly between each coil that transformer coats outside it and inner silicon steel sheet insert group be provided with the heat radiation guide plate of a hollow form, the fluid that heat absorption is arranged according to heat radiation guide plate inner filling, by flowing of fluid, the high heat of transformer inside can be guided rapidly and be dispersed into the external world, and the heat radiation supplementary structure setting that cooperates on the heat radiation guide plate outer edge surface ring respectively to establish the heat radiation scale of protrusion, area of dissipation is increased relatively, and can reach the effect of rapid cooling, make the internal high temperature of transformer can obtain suitable improvement, effectively reduce the heating temp of whole transformer, overcome traditional transformer effectively and produced the bad shortcoming of heat radiation in the use, can reach the service life of the whole transformer of proper extension further and increase its fail safe, and have the effect that improves transformer use power.

In sum, heat dissipating device of transformer of the present utility model, its insert group structure by the heat radiation guide plate is provided with, cooperate the increase of heat radiation scale area of dissipation, make its running heat that can rapidly transformer inside be produced, be rejected to the external world apace, guarantee the safety of the inner package assembly of whole transformer and suitable its useful life of prolongation, can reach the cost that reduces maintenance and change the outfit, have more effect safe in utilization and raising power; No matter it structurally or all have on the function significantly and to improve, really is a new and innovative, progressive, practical new design.
