Abstract
The invention relates to the technical field of the power distribution cabinets and in particular relates to an air outlet structure of a power distribution cabinet. The air outlet structure comprises a cabinet body and an air outlet formed in the top of the cabinet body, wherein the air outlet is a radial circular-ring-shaped structure composed of a plurality of slotted holes, and wherein each slotted hole is composed of a plurality of square holes arranged orderly. The ventilation system of the low-voltage power distribution cabinet is re-designed and modified and replaced with the outwards radial air outlet; the air outlet structure is similar with a fan in heat dissipation manner, so that the heat dissipation effect is better, the air flow channel is optimized and the heat dissipation efficiency is improved; an enough ventilation channel can be formed, so that sufficient ventilation effect is achieved, excellent ventilation and heat dissipation are realized, and the protection grade IP4X is satisfied.
Description
Technical field
The present invention relates to power distribution cabinet technical field, relate in particular to a kind of low-voltage distribution cabinet exhaust vent structure.
Background technology
Low-voltage distribution cabinet has been widely used in power distribution network, the heat producing when low-voltage distribution cabinet is normally worked raises low-voltage distribution cabinet internal temperature, it is bad that problem of temperature rise solves, and can cause low-voltage distribution cabinet body or internal unit premature aging, even can produce major accident when serious.Therefore, the heat radiation of low-voltage distribution cabinet and cooling problem affect very large for long-term, the stable operation of low-voltage distribution cabinet, can not be ignored.
On the cabinet of low-voltage distribution cabinet, ventilating opening is set, utilizes air to carry out heat exchange and reach heat radiation object, there is certain radiating effect.But still there is the obstructed problem of heat dissipation channel in the ventilating opening arranging at present, has the hidden danger that temperature rise exceeds standard.
Summary of the invention
The object of the invention is to propose a kind of low-voltage distribution cabinet exhaust vent structure, the heat that the electric component in cabinet can be produced fully distributes, simple in structure, reasonable in design.
For reaching this object, the present invention by the following technical solutions:
A kind of low-voltage distribution cabinet exhaust vent structure, comprises cabinet and is arranged on the air outlet at cabinet top, the serve as reasons radial circular ring structure of several bar holes compositions of described air outlet, and wherein, each bar hole is made up of the multiple square holes that are arranged in order.
Wherein, described square hole is provided with protruding curved edge to the periphery, and described edge is towards the interior lateral buckling of described cabinet.
Wherein, described square hole and described cabinet outer surface junction are curved and be smoothly connected.
Wherein, the wide of described square hole is 1-2cm, and the length of described square hole is 1-2cm, and the angle between described bar hole is 10 °-20 °.
Wherein, also comprise and be arranged near the air exhausting device of air outlet, described air exhausting device is axial fan.
Wherein, described cabinet inside is also provided with Temperature Humidity Sensor and control unit, and described Temperature Humidity Sensor is all connected with control unit with air exhausting device.
Beneficial effect:
Compared with prior art, the present invention includes cabinet and be arranged on the air outlet at cabinet top, the serve as reasons radial circular ring structure of several bar holes compositions of described air outlet, wherein, each bar hole is made up of spaced square hole.The utility model is by improving design to the ventilating system of low-voltage distribution cabinet, employing is the air outlet of outside radial structure, because this air outlet structure is similar to the radiating mode of fan, better heat-radiation effect, has optimized gas channel, has improved radiating efficiency, can form enough vent passages, both possessed enough ventilation effects, reached good ventilation and heat, met again the degree of protection of IP4X.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of low-voltage distribution cabinet exhaust vent structure of providing of the specific embodiment of the invention.
In figure:
1-cabinet; 2-air outlet; 3-circular ring structure.
Embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the structural representation of a kind of low-voltage distribution cabinet exhaust vent structure of providing of the specific embodiment of the invention.As shown in Figure 1, a kind of low-voltage distribution cabinet exhaust vent structure of the present invention comprises cabinet 1 and is arranged on the air outlet 2 at cabinet 1 top, the serve as reasons radial circular ring structure 3 of several bar holes composition of described air outlet 2, wherein, each bar hole is made up of the multiple square holes that are arranged in order.
The present invention is by improving design to the ventilating system of low-voltage distribution cabinet, employing is the air outlet 2 of outside radial structure, because this air outlet 2 structures are similar to the radiating mode of fan, better heat-radiation effect, has optimized gas channel, has improved radiating efficiency, can form enough vent passages, both possessed enough ventilation effects, reached good ventilation and heat, met again the degree of protection of IP4X.
Described square hole is provided with protruding curved edge to the periphery, and described edge is towards the interior lateral buckling of described cabinet 1.This structure is beneficial to extraneous cold wind and enters in cabinet, has expanded the size of the interior air outlet 2 of cabinet 1 simultaneously, and the hot gas being conducive in cabinet 1 more distributes.
Described square hole and described cabinet 1 outer surface junction are curved and be smoothly connected.The smooth structure of arc has expanded the size of cabinet 1 outer surface air outlet 2, is conducive to extraneous cold wind and enters in cabinet, mutual with the hot gas in cabinet, can reach good radiating effect.
The wide of described square hole is 1-2cm, and the length of described square hole is 1-2cm, and the angle between described bar hole is 10 °-20 °.
Also comprise and be arranged near the air exhausting device of air outlet 2, described air exhausting device is axial fan, is also provided with Temperature Humidity Sensor and control unit, and described Temperature Humidity Sensor is all connected with control unit with air exhausting device.By air outlet 2, the heat that electric component in power distribution cabinet can be produced fully distributes; If the heat that the electric component in cabinet produces makes air outlet 2 be not enough to distribute completely, humiture information in Temperature Humidity Sensor detects power distribution cabinet is during higher than the set point of control unit, control system will start axial fan and further strengthen heat radiation, good heat dissipation effect.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
