Abstract
The utility model relates to a forced air-cooled explosion preventive electric box for mines, particularly an explosion preventive box for installing power electronic devices under coal mines. The forced air-cooled explosion preventive electric box for mines comprises a box body and a copper heat radiator which is installed in the box body, wherein heat radiating fins of the copper heat radiator are exposed out of the box body. The utility model is characterized in that an air channel which covers the heat radiating fins of the copper heat radiator is installed on the outer surface of the box body, and an explosion preventive blower fan is installed on the air channel. The utility model has the advantages that the heat radiating efficiency is high, the heat radiating problem of large capacity power electronic devices under coal mines when working in the explosion preventive electric box is solved on one hand and the service lives of the large capacity power electronic devices are guaranteed. The utility model is particularly suitable for large power electronic devices under coal mines.
Description
Technical field
The utility model relates to a kind of explosion-proof tank of installation power electronic equipment of underground mine use.
Background technology
In the coal production field, the power electronic equipment under the coal mine all requires to be installed in the explosion-proof tank.Existing explosion-proof tank is an airtight casing, to the power component heat dissipation problem in the device all is to adopt to establish a copper radiator in casing usually, the electronic power heater element is installed in above the copper radiator, the fin of radiator is exposed at outside the casing, by the air in the tunnel it is carried out natural cooling.Its weak point is that the tunnel of down-hole is narrow, and the natural cooling radiating efficiency is extremely low, makes the thermal diffusivity extreme difference of power electronic equipment, and capacity is limited, and service condition badly causes its useful life.
The utility model content
The purpose of this utility model is intended to overcome the above-mentioned deficiency of existing explosion-proof tank, provides a kind of radiating efficiency high forced air-cooled mine explosion electric box.
The formation of this forced air-cooled mine explosion electric box comprises that casing and its fin that is installed in the casing are exposed at the outer copper radiator of casing, it is characterized in that an explosion-proof fan being installed on described air channel in that an air channel on the fin that covers on copper radiator is installed on the outer surface of casing.Blow to fin by blower fan during work, carry out air blast cooling.
Described explosion-proof fan can be arranged on an end in air channel, is installed on the casing with support, and cold wind is from the air inlet air intake, and by the air channel of flowing through after the blower fan pressurization, the heat of fin is exchanged at a high speed by cold wind and takes away, and discharges hot blast from the other end in air channel.
Described explosion-proof fan can be arranged on the position over against fin in air channel, the air channel two ends be openend.Directly dispel backing by explosion-proof fan, cold wind and fin carry out that heat exchange is laggard goes into the air channel, discharge hot blast from two ends.In this version, a plurality of air outlets can be opened in the air channel.
Compared with the aforementioned existing similar products, the advantage of this forced air-cooled mine explosion electric box is the radiating efficiency height, has solved the heat dissipation problem when the large-capacity power electronic installation under the coal mine is worked in explosionproof electric box on the one hand, makes its useful life secure; Improved the capacity of the installation power electronic equipment of explosionproof electric box on the other hand; Security performance is good, and the high power electronic equipment that is particularly suitable under the coal mine uses.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Embodiment
Embodiment 1:
Shown in Fig. 1～3, the formation of this forced air-cooled mine explosion electric box comprises that casing 1 and its fin 2 that is installed in the casing 1 are exposed at the outer copper radiator 3 of casing, in that an air channel 4 on the fin 2 that covers on copper radiator is installed on the outer surface of casing 1, an explosion-proof fan 7 is installed on air channel 4.Explosion-proof fan 7 can be arranged on an end in air channel, is installed on the casing 1 with support 6.5 are the transition air duct among the figure, and 8 is the electronic power heater element.Cold wind is from the air inlet air intake, and by the air channel of flowing through after the blower fan pressurization, the heat of fin is exchanged at a high speed by cold wind and takes away, and discharges hot blast from the other end in air channel.
Embodiment 2:
Referring to Fig. 4, in the present embodiment, explosion-proof fan 9 is arranged on the position over against fin 2 in air channel 10, and the two ends in air channel are openend.Directly dispel backing by explosion-proof fan, cold wind and fin carry out that heat exchange is laggard goes into the air channel, discharge hot blast from two ends.In this version, a plurality of air outlets 11 can also be opened in the air channel, the structural representation in the air channel that provides referring to Fig. 5～6, and 12 is fresh air inlet among the figure, 13 for installing the installing holes of explosion-proof fan.
Claims (3)
1, a kind of forced air-cooled mine explosion electric box, its fin that comprises casing and be installed in the casing is exposed at the outer copper radiator of casing, it is characterized in that an explosion-proof fan being installed on described air channel in that an air channel on the fin that covers on copper radiator is installed on the outer surface of casing.
2, explosionproof electric box as claimed in claim 1 is characterized in that described explosion-proof fan is arranged on an end in air channel, is installed on the casing with support.
