Switch cubicle caloric value is very big, particularly high current copper bar inlet wire scheme, and narrow and small inlet wire copper bar space limits heat and distributed, greatly
The heat aggregation of amount makes switch cubicle upper back, and switch cubicle temperature rise is too high, and longtime running very likely uses electrification.
Utility model content
For above mentioned problem, the utility model carry existing for the back door of middle pressure handcart-type high-current switch in the prior art
For a kind of high-current switch back door for possessing heat sinking function.
The technical solution of the utility model is as follows：
A kind of high-current switch back door for possessing heat sinking function, has been abound with the outside of the high-current switch back door
With the aluminum radiating tube of the vertically disposed tubulose in high-current switch back door, it is provided with the inside of the high-current switch back door
Copper absorber plate, the copper suction for the tubulose being be arranged in parallel with high-current switch back door is abound with the inside of the copper absorber plate
Heat pipe.The rear door of switch cabinet structure is merged the high heat dispersion of the high thermal conductivity of copper and aluminium, and switch cubicle upper back is gathered
The heat of collection, absorbed quickly by the absorber plate on the inside of back door, pass to aluminum back door rapidly afterwards, on the outside of aluminum back door
Radiating tube is discharged outside cabinet quickly.
As further improvement of the utility model, the aluminum radiating tube is arranged in the outside at high-current switch back door
Into circle, aluminum radiating tube parallel of the opening for elongated rectangular shape is used between circular surrounding and high-current switch back door housing
Arrange and be abound with.By many experiments and theoretical research, arrangement of this structure design compared to routine of aluminum radiating tube is found
Mode has optimal radiating effect, can to the full extent by incoming-line busbar run caused by heat leading by Rear Door
Outside hot heat sinking function discharge cabinet.
As further improvement of the utility model, the high-current switch back door is one of the forming structure, the copper
Riveted between matter absorber plate and high-current switch back door by copper aluminium welding technique.
The beneficial effects of the utility model are as follows：
The utility model possesses the high-current switch back door of heat sinking function, and producing one kind using fine forging technology possesses
The aluminium alloy back door of heat sinking function, to the full extent by incoming-line busbar run caused by the heat heat conduction and heat radiation that passes through Rear Door
Outside function discharge cabinet, improve switch cubicle service condition.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The structure of existing high-current switch 3 is special as shown in figure 1, larger running current makes switch cubicle caloric value very big
It is not high current copper bar inlet wire scheme, narrow and small inlet wire copper bar space limits heat and distributed, and substantial amounts of heat is gathered in Fig. 1
Shown heat aggregation position 2, makes switch cubicle upper back make switch cubicle temperature rise too high, electricity consumption thing very likely occurs for longtime running
Therefore.
A kind of structure at the high-current switch back door for possessing heat sinking function of the utility model as illustrated in figs. 2-7, wherein, figure
2-4 shows the outboard structure at the high-current switch back door, and Fig. 5-7 shows the inner side knot at the high-current switch back door
Structure.It is abound with the outside at high-current switch back door 1 and is radiated with the aluminum of the vertically disposed tubulose in high-current switch back door
Pipe 4.Copper absorber plate 5 is provided with the inside of high-current switch back door, the inner side of copper absorber plate 5 has been abound with opens with high current
Close the copper endothermic tube 6 for the tubulose that cabinet back door 1 be arranged in parallel.The rear door of switch cabinet structure is by the high thermal conductivity of copper and the height of aluminium
Heat dispersion is merged, and the heat of switch cubicle upper back aggregation, is absorbed quickly by the absorber plate on the inside of back door, rapid afterwards to pass
Aluminum back door is passed, is discharged quickly outside cabinet by the radiating tube on the outside of aluminum back door.
As a kind of preferred embodiment of the present utility model, aluminum radiating tube 4 is in the outside at high-current switch back door 1
Circle as shown in Figure 2 is arranged into, opening is used as elongated rectangular shape between the circular surrounding and the housing of high-current switch back door 1
Aluminum radiating tube 4 is arranged in parallel and is abound with.By many experiments and theoretical research, it is found that this structure of aluminum radiating tube 4 is set
The arrangement mode counted compared to routine has optimal radiating effect, incoming-line busbar can be run to the full extent caused by
