For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of negative pressure heat radiation type electrical appliance cabinet is provided, comprise: negative-pressure air fan, aspirating air pipe, basis casing, moving box door and air strainer, described negative-pressure air fan is arranged on the top of basic casing, described moving box door is symmetricly set on the front of basic casing, described air strainer is symmetricly set on respectively on moving box door, described aspirating air pipe comprises three vertically sealing plastic tubes, described three vertical sealing plastic tubes are evenly distributed in basic casing, described three tops of vertically sealing plastic tube are provided with the ventilation duct being connected with the air inlet of negative-pressure air fan, described three are vertically evenly placed with respectively several suction holes on sealing plastic tube.
In a preferred embodiment of the present invention, on the air outlet of described negative-pressure air fan, be provided with dust cover.
In a preferred embodiment of the present invention, in described basic casing, be provided with two row components and parts card article is installed, described two row components and parts are installed card article and are separately positioned in the interval of three vertical sealing plastic tubes.
In a preferred embodiment of the present invention, on described negative-pressure air fan, be provided with temperature detect switch (TDS).
The invention has the beneficial effects as follows: a kind of negative pressure heat radiation type electrical appliance cabinet that the present invention points out; under the drive of negative-pressure air fan; by three suction holes that vertically seal on plastic tube, in bin, evenly absorb heat; do not stay dead angle; cooling protection to components and parts is effective; air strainer has guaranteed to enter the cleanliness of the air of bin, in order to avoid dust granule impacts the work of components and parts.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of negative pressure heat radiation of the present invention type electrical appliance cabinet one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, negative-pressure air fan, 2, aspirating air pipe, 3, basic casing, 4, moving box door, 5, air strainer, 6, components and parts install card article, 7, dust cover.
Embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of negative pressure heat radiation type electrical appliance cabinet, comprise: negative-pressure air fan 1, aspirating air pipe 2, basis casing 3, moving box door 4 and air strainer 5, described negative-pressure air fan 1 is arranged on the top of basic casing 3, described moving box door 4 is symmetricly set on the front of basic casing 3, described air strainer 5 is symmetricly set on respectively on moving box door 4, described aspirating air pipe 2 comprises three vertically sealing plastic tubes, described three vertical sealing plastic tubes are evenly distributed in basic casing 3, described three tops of vertically sealing plastic tube are provided with the ventilation duct being connected with the air inlet of negative-pressure air fan 1, described three are vertically evenly placed with respectively several suction holes on sealing plastic tube.During negative-pressure air fan 1 work, the interior generation negative pressure of aspirating air pipe 2, suction hole starts to carry out air-breathing work, take away the heat in bin, in casing, produce negative pressure simultaneously, outside air enters box house by air strainer 5, filters out airborne dust granule, avoids components and parts to cause harmful effect.
