Description
Technical field
The present invention relates to a kind of power distribution cabinets, particularly a kind of high efficiency and heat radiation power distribution cabinet.
Background technology
Existing low-voltage distribution cabinet is generally the cabinet of cuboid, and front is equipped with instrument, control panel and display, for work
Make personnel's operation or monitoring, be internally provided with mutually independent element cell, bus-bar room, cable vault etc..Therefore low-voltage distribution cabinet is general
It is all heavier, it carries very difficult.Secondly because its internal high current busbar, cable and electronic component operational heat, therefore meeting
Power distribution cabinet internal temperature is caused to raise.And the radiating mode of existing low-voltage distribution cabinet is all by being set in cabinet top into air draft grid
Lattice set on the interlayer board between electrical drawer and electrical drawer air grid to carry out thermal wind exhausting, realize the purpose of cooling.This
The aeration-cooling effect of kind is very poor, so as to easily lead to the malfunction in electric prospection circuit so that and electric elements service life reduces,
Influence the operation of electrical equipment.
In addition, power distribution cabinet is often unavoidably attacked be subject to water, if water drips or tilts from the plan vertical of power distribution cabinet
The housing slot to drip enters inside power distribution cabinet, and the element of power distribution cabinet will be soaked in water, can not so as to cause electrical equipment
Normal operation.
The content of the invention
The goal of the invention of the present invention is：In view of the problems of the existing technology, a kind of high efficiency and heat radiation power distribution cabinet is provided.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of high efficiency and heat radiation power distribution cabinet, including cabinet and cabinet door, the cabinet door is movably connected on cabinet, the top of the cabinet
And bottom is equipped with aeration structure, the cabinet is equipped with aeration structure on other three sides in addition to the cabinet door one side.
As the preferred embodiment of the present invention, the aeration structure on the cabinet side is heat emission hole, the heat emission hole it is upper
Along with outwardly extending water blocking cover edge.
As the preferred embodiment of the present invention, the water blocking cover edge has reclinate cambered surface.
As the preferred embodiment of the present invention, the heat emission hole is horizontally extending elongate holes.
As the preferred embodiment of the present invention, at the top of the cabinet and the aeration structure of bottom is screen frame.
As the preferred embodiment of the present invention, be additionally provided with cover board above screen frame at the top of the cabinet, the cover board with it is described
Ventilative gap is formed between screen frame.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, after electric elements generate heat in cabinet, temperature rises, and hot-air is arranged by the aeration structure of cabinet top and cabinet side
Go out, and cold air is constantly supplemented by the aeration structure of cabinet lower part, and cabinet is made to form a natural ventilation channel from bottom to top,
Without using achieving the purpose that heat dissipation under conditions of the radiator of external power supply.
2nd, water blocking cover edge can prevent the water that the side wall along power distribution cabinet flows down from entering heat emission hole, and then prevent water from heat emission hole
It flows into power distribution cabinet；The cover board at the top of cabinet prevents rainwater from directly dripping into ventilation screen frame simultaneously, and then flows into cabinet, leads
The element of power distribution cabinet is caused to be immersed in water, is unable to operate normally so as to cause electrical equipment.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is left view of the present invention.
It is marked in figure：1- cabinet doors, 2- cabinets, 3- ventilation screen frames, 4- cover boards, 5- water blocking cover edges, 6- heat emission holes.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Embodiment 1
A kind of high efficiency and heat radiation power distribution cabinet, including cabinet 1 and cabinet door 2, the cabinet door 2 is movably connected on cabinet 1, the cabinet 1
Top and bottom be equipped with ventilation screen frame 3, the cabinet 1 is equipped on other three sides in addition to 2 one side of cabinet door
Heat emission hole 6.
Further, the upper edge of the heat emission hole 6 has outwardly extending water blocking cover edge 5.
Further, the water blocking cover edge 5 has reclinate cambered surface.
Further, the heat emission hole 6 is horizontally extending elongate holes.
Further, cover board 4 is additionally provided in the top of the 1 top portion ventilation screen frame 3 of cabinet, the cover board 4 and the ventilation
Ventilative gap is formed between screen frame 3, prevents rainwater from dripping into ventilation screen frame 3, and then making for power distribution cabinet is influenced into cabinet 1 is interior
With.
After 1 electric elements generate heat in cabinet, temperature rises, the ventilation knot that hot-air passes through 1 top of cabinet and 1 side of cabinet
Structure is discharged, and cold air is constantly supplemented by the aeration structure of 1 lower part of cabinet, and cabinet 1 is made to form one from bottom to top and is led to naturally
Air passage achievees the purpose that heat dissipation under conditions of the radiator without using external power supply.Meanwhile water blocking cover edge 5 can prevent edge
The water that the side wall of power distribution cabinet flows down enters heat emission hole 6, and then prevents water from being flowed into from heat emission hole 6 in power distribution cabinet, ensures power distribution cabinet
It is safe to use.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
