Embodiment

For the content of the invention, feature and effect of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate Accompanying drawing detailed description is as follows, refers to Fig. 1-Fig. 3.

Embodiment 1 is described as follows with cabinet I to be split type：

As shown in Figure 1 and Figure 2：Cabinet I is made up of radiator 1, A chamber enclosures 2 and B chamber enclosures 3 and is mutually permanently connected into one Body, the top and bottom of cabinet I are respectively fixed with top cover labyrinth 4 and lower sealing cover 5；Dissipated on radiator 1 with staggered relatively Backing 6 and A fin 6-1, two dissipation backings 6 and A fin 6-1 are that the centre separated carries isolation strip；A chamber enclosures 2 are solid The side of radiator 1 is scheduled on, space is left between A chamber enclosures 2 and radiator 1 and forms A chambers 7, A of the fin 6 close to A chamber enclosures 2 In chamber 7, B chamber enclosures 3 are fixed on the opposite side of radiator 1, and space is left between B chamber enclosures 3 and radiator 1 and forms B chambers 8, A radiatings Piece 6-1 is in the B chambers 8 of B chamber enclosures 3；Two square holes are provided with A chamber enclosures 2, screen pack 9, top are fixed with its upper aperture The hot-air being had warmed up in sealing electric box is constantly flow back to sealing by hole as the venthole of A chambers 7 by A chambers 7 in cabinet I Electric box simultaneously circulates in sealing electric box, as heat dissipation capacity can not among screen pack 9 and A chamber enclosures 2 increase air ejector fan, Blast cushion chamber framework 10, induced draught fan 11 and A screen packs 12 are fixed with lower square hole successively, induced draught fan 11 is filtered by A Net 12 by the pressure of hot-air in electric box it is buffered after suction A chambers 7, hot-air is transmitted to by the fin 6 on radiator 1 A fin 6-1 at B chambers 8；Also two square holes are provided with B chamber enclosures 3, ventilating fan 13 and B mistakes are fixed with successively at its upper aperture Filter screen 14, dust collection chamber framework 15 and C screen packs 16 are fixed with successively at lower square hole, passes through the He of ventilating fan 13 at upper aperture B screen packs 14 are circulated the hot-air discharge in B chambers 8 and outside sealing electric box, and extraneous cold air is again outside B chambers 3 times square holes of shell cold sink 6-1 after C screen packs 16, dust collection chamber framework 15 enter B chambers 8, if heat dissipation capacity can not be Increase induced draught fan among C screen packs 16 and B chamber enclosures 3；Described all parts use refractory seals when fixing Glue seals to junction；A chambers 7 and B chambers 8, it is impossible to wind is gone here and there, to be isolated entirely from A chambers 7 and B chambers 8；Outside described A chambers Left between shell 2 and radiator 1 and leave space between space and A chambers 7 and B chamber enclosures 3 and radiator 1, be good in order to ensure to have Ventilation, to reach the effect of good isolation radiating.

During work, the device for cooling is placed in sealing electric box, seals the outer STH of electric box by B chamber enclosures 3 Hold towards external environment condition；Hot blast in closing electric box is sucked A chambers 7 by induced draught fan 11, and is discharged from screen pack 9 in sealing electricity Being circulated in gas tank, the hot-air for being at the same time used to suck raises the temperature of fin 6 of the side of A chambers 7, then on fin 6 Heat is transmitted to the fin 6-1 of the side of B chambers 8, then, is discharged the air to have cooled by the ventilating fan 13 on B chamber enclosures 3, Because air is in electric box outermost loops, the cold air of outside is further through the C screen packs 16 and dust collection below B chamber enclosures 3 Chamber framework 15 enters B chambers 8, and the fin 6-1 of the side of B chambers 8 is cooled down, and the heat conduction to go round and begin again can realize sealing electricity The isolation radiating cooling effect of gas tank.

Its advantage is：It is simple in construction, it is easy to manufacture, cost is low, and employing isolation cooling method, it has a wide range of application, real It is strong with property, such as the electrical equipment that can be used on family, factory, mine and military industry equipment needing dust-proof temp-lowering, it ensure that electric appliance and electronic member When gas part works, not by dust pollution and good cooling effect.

Embodiment 2 is described as follows with cabinet I for integral type：

As shown in Figure 3：Cabinet I is that integral type is 3 radiator 1, A chamber enclosures 2 and B chamber enclosures extrusion formings into one Body, other structures, operation principle, advantage are identical with embodiment 1.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to utility model Scope be defined, on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this practicality The various modifications of new technical scheme operation and improvement, the protection domain of the utility model claims book determination all should be implemented It is interior.
