Specific embodiment
Below in conjunction with the attached drawing in the embodiment shown in the embodiment of the present application, to the embodiment shown in the embodiment of the present application
In technical solution be clearly and completely described.
Referring to Fig. 1, a kind of low voltage drawing-out switching carbinet, successively include from top to bottom exhaust fan room 1, drawer room 2 and
Supply fan room 3；The drawer room 2 includes upper layer cavity 201, drawer 202, lower layer's cavity 203 and guide rail 204, the drawer
202 slide on the guide rail 204；It is provided with exhaust fan 101 in the exhaust fan room 1, is provided in 2 side of drawer room
Exhaust column 102, the exhaust fan room 1 are connected by the exhaust column 102 with upper layer cavity 201；It is set in the supply fan room 3
It is equipped with breeze fan 301,2 other side of drawer room is provided with air supply tube 302, is provided with and send below the guide rail 204
Wind cavity 303, the guide rail 204 are provided with two and are separately fixed at the upper surface both ends of air-supply cavity 303, the air-supply wind
Machine 301 is connected by the air supply tube 302 with the air-supply cavity 303.
303 upper surface of air-supply cavity of the application offers air holes, for the wind in air supply tube 302 to be entered and left drawer 22
In, while cavity 303 of blowing is made of metal, provides supporting force for drawer 202, and therefore, the low-voltage drawing out type electric of the application
Cabinet, which eliminates, no longer needs to supporting parts required for being equipped with drawer 202, thus the draw-out type low-voltage switch cabinet structure of the application it is simple,
It is compact, it is user-friendly.
The low voltage drawing-out switching carbinet of the application is sucked the cold wind in environment by breeze fan 301, is sent by air supply tube 302
Enter in drawer 202, while the suction of exhaust fan 101 to form negative pressure in drawer 202, accelerates the wind speed of breeze fan 301,
To accelerate heat exchange.Simultaneously as heat often moves upwards, thus the wind that is blown into of breeze fan 301 is from drawer
202 bottoms enter in drawer, and induced draft fans 101 are from drawer top heat extraction, the thermodynamic principles made full use of, therefore dissipate
Thermal effect is very good.
It is described air-supply cavity 303 width it is equal with the width of the drawer 202, it is described air-supply cavity 303 length and
The equal length of the drawer 202.Cavity 303 of blowing is identical as the size of drawer 202, and the needs of cavity 303 of on the one hand blowing are held
The weight of drawer 202 is held in the palm, on the other hand can preferably be blown in drawer 202, so that wind can be blown down in drawer 202,
Can have good ventilation effect, therefore perfect heat-dissipating.
The top surface of the air-supply cavity 303 offers air hole 3031, and the air hole 3031 includes that several groups are uniformly arranged
The circular through-hole of column evenly distributed has several rectangular open-works in one week on the outside of each circular through-hole.The air hole
3031 are located between two guide rails 204.Air hole is evenly distributed in air-supply 303 upper surface of cavity, and rectangular open-work
It is uniformly distributed along circular through-hole, wind is blown down in drawer 202 with 360 ° of angle, so that the area blowed air over is maximum
Change, improves heat-sinking capability.
The drawer 202 is the cuboid of upper surface opening, in the shell for the drawer 202 being located in the drawer room
Surface offers evenly distributed through-hole.Other than front, lap can divulge information the surface of shell of drawer 202, increase
Draught area, improves ventilation effect.
In conclusion the low voltage drawing-out switching carbinet of the application is by under the action of blower 101 and breeze fan 301,
Heat exchange is accelerated, meanwhile, the thermodynamic principles that the setting position of exhaust column 102 and air supply tube 302 makes full use of, therefore dissipate
Thermal effect is very good.
