Description
Technical field
The present invention relates to electrical cabinet body more particularly to a kind of electrical cabinets with air current circulation.
Background technique
The external plate hull shape that is equipped with is at a rectangular cabinet body, vertical beam and cross after electrical cabinet usually forms frame by crossbeam vertical beam
Beam is hollow structure, and surface is provided with fixation hole of the equidistant fixation hole as fixed component mounting plate, when electric device band
When electricity work, heat can be generated simultaneously, cause temperature to be increased to beyond electrical device to guarantee that the heat generated accumulates not in cabinet
The normal working temperature of part.It is generally equipped with cooling system on the cabinet.
Currently, electrical cabinet cooling system generally uses two ways.First way install additional on the cabinet give, air draft wind
Fan, when starting fan, colder air is sent into interior of the cabinet, the hotter air discharge of interior of the cabinet, this mode outside cabinet body
It is at low cost, heat dissipation effect is obvious, but the dust that is inevitable in cabinet body outside air of disadvantage and moisture content enter cabinet body 0
Inside is easy to impact the insulation performance of electric device.
The second way is such as sky-water, air-air, oil-air radiator using radiator mode, using this kind of mode
It can guarantee the IP degree of protection of unit, but maximum the disadvantage is that higher equipment cost, occupied space are big.
Summary of the invention
It is an object of the invention to overcome disadvantages described above, a kind of reliable performance is provided cost is relatively low the preferable band of heat dissipation effect
There is the electrical cabinet of air current circulation.
The purpose of the present invention is achieved by the following technical programs, a kind of electrical cabinet with air current circulation,
Including plate shell, crossbeam, vertical beam, fan, plate shell is located at outside the frame being made of crossbeam and vertical beam and forms closed cabinet body, further includes
Air intake cover, the vertical beam and crossbeam are hollow structure and are equipped with mounting hole and exhaust vent, and portion on the cabinet is arranged in the fan,
The air outlet of fan that hot wind is sucked out of cabinet is connected with the air intake vent of air intake cover, the air outlet of air intake cover from the top of vertical beam and
Vertical beam hollow passageway communicates.
Preferably, the top of cabinet body center is arranged in the fan.
Preferably, for the processing conducive to vertical beam, the mounting hole and exhaust vent that the vertical beam is equipped with are equidistantly, for benefit
It further include plug in the heat dissipation of hot wind, the plug is for sealing the extra mounting hole in part, conducive to hot wind uniformly from vertical beam
Blowout in hollow passageway.
Preferably, the air outlet of the air intake cover is also also to communicate with the crossbeam hollow passageway on cabinet body top.
It preferably, further include heater, the heater is arranged inside air intake cover.
The method have the benefit that: the fan sucking intracorporal hot-air of cabinet is introduced to by vertical beam by air intake cover
It is interior, an air duct circulation, which is formed, in interior of the cabinet realizes that circulation in cabinet, hot wind carry out heat exchange with extraneous by the plate shell of metal,
Without increasing special heat-exchange apparatus, and it is not necessary that wind sucking cabinet body outside cabinet body is just able to satisfy heat dissipation effect, cabinet ensure that
The degree of protection of body.In particular, being additionally arranged heater in air intake cover, when environment temperature is lower, cabinet body is effectively prevented
The interior operating temperature for forming condensation and guaranteeing interior of the cabinet electric elements.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the embodiment of the present invention；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the B-B cross-sectional view of Fig. 2；
Fig. 4 is the present embodiment beam structure schematic diagram；
Fig. 5 is the present embodiment vertical beam structural schematic diagram.
Specific embodiment
Below in conjunction with drawings and examples, the invention will be further described.
Referring to attached drawing, a kind of electrical cabinet with air current circulation comprising plate shell 1, crossbeam 2, vertical beam 3, fan 4,
Heater 7, plate shell 1 are located at outside the frame being made of crossbeam 2 and vertical beam 3 and form closed cabinet body, further include air intake cover 5, described
Vertical beam 3 and crossbeam 2 are the interior hollow structure equipped with hollow passageway and are equipped with multiple mounting holes 6, and mounting hole 6 is also as hollow logical
The air outlet in road, in order to be conducive to the processing of vertical beam 3, the mounting hole that the vertical beam 3 is equipped with is that hole 6 is mounted equidistant, in order to be conducive to heat
The heat dissipation of wind further includes plug 8, the plug 8 for sealing the extra mounting hole 6 in part, the setting of fan 4 cabinet body just
The top at center, the air outlet that the fan 4 of hot wind is sucked out of cabinet are connected with the air intake vent of air intake cover 5, the air outlet of air intake cover 5
It with the hollow passageway of the hollow passageway of vertical beam 3 and the crossbeam 2 on cabinet body top is to communicate from the top of vertical beam 3, the heater
It is arranged inside air intake cover 5.
When in-cabinet temperature is higher, the suction for the upward direction that the rotation of fan 4 generates accelerates interior of the cabinet hot-air to rise,
And by hot-air by being sucked inside air intake cover 5 after fan 4,5 air inlet of air intake cover, after hot-air enters 5 inside of air intake cover,
The vertical beam 3 connecting with 5 air outlet of air intake cover is blown under the action of fan 4, inside 2 hollow passageway of crossbeam, then by vertical beam 3,
The mounting hole 6 that crossbeam 2 is not enclosed is blown out, the hot-air of blowout realization and cabinet and the plate shell 1 close with mounting hole 6 contacts
The external space is into heat exchange, to reduce the air themperature in space in cabinet.Meanwhile circulation accelerates electrical component and cabinet in buoyance chamber
The heat exchange of interior air improves the heat exchanger effectiveness of electrical component.
When, there are when condensation risk or too low in-cabinet temperature, heater 7, fan 4 start, and air is in fan in cabinet in cabinet
By being sucked inside air intake cover 5 after fan 4,5 air inlet of air intake cover under 4 suctions, added inside air intake cover 5 by heater 7
Heat at relatively warm air, the relatively warm air after heating be blown under the action of fan 4 vertical beam 3 being connect with 5 air outlet of air intake cover,
Inside 2 hollow passageway of crossbeam, then blown out by the mounting hole 6 that vertical beam 3, crossbeam 2 are not enclosed, the hot-air of blowout by with peace
It fills the close plate shell 1 in hole 6 to contact, and improves 1 internal surface temperature of plate shell, effectively prevent cabinet body inner surface condensation.Meanwhile it realizing
Electrical component is evenly heated.
It is above one embodiment of the present invention, a preferred demonstration example.The claimed range of the present patent application
It is not only limited in the embodiment.All technical solutions equivalent with the present embodiment all belong to the scope of protection of the present invention.
