Description
Technical field
The utility model is related to low voltage switch equipment technical field, especially a kind of improved AC low-tension switch cubicle knot
Structure.
Background technology
AC low-tension switch cubicle is applied to the industries such as power plant, oil, chemical industry, metallurgy, weaving, skyscraper, used as defeated
The conversion of electricity, distribution and electric energy is used.In summer, because ambient temperature is high, inside switch cabinet electric elements in addition itself
Radiating, can cause the temperature in cabinet higher.The U of Chinese utility model patent CN 204927881 disclose a kind of AC low-tension
Switch cubicle, by setting radiator and louvre, serves the effect for reducing cabinet body temperature.But, this radiator structure pair
It is uneven in the radiating effect of various pieces in cabinet, apart from radiator and louvre position good heat dissipation effect closer to the distance,
Distant position radiating effect is poor.The installation rack position concentrated especially is installed in electric elements, due to air current flow
Resistance is big, causes radiating effect not good.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of improved AC low-tension switch cabinet structure, can solve the problem that
The deficiencies in the prior art, improve the radiating effect at mounting bracket position.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of improved AC low-tension switch cabinet structure, including cabinet, are provided with several mounting brackets, the cabinet in cabinet
Air inlet and air outlet are provided with body, circular set is fixed with by support on air inlet, ajutage is plugged with circle set, sent
The air intake of airduct is connected with air blower, and ajutage is arranged on the bottom of mounting bracket, and ajutage is set towards the side of mounting bracket
The bottom for having some groups of exhaust vents, mounting bracket is provided with and the one-to-one radiating fin of exhaust vent, exhaust vent and radiating fin
Gap coordinates, and radiating fin is provided centrally with blind hole, and the both sides of radiating fin are provided with arc groove, blind hole and arc groove it
Between be provided with several through holes, the through hole on adjacent arc groove is staggered, and ventilating fan is provided with air outlet.
Preferably, the ajutage outside is enclosed with thermal insulation layer.
Preferably, being provided with filter screen between the circular set and air inlet.
The beneficial effect brought using above-mentioned technical proposal is：The utility model is set in air inlet by circular set
Actively air-supply and passive air-supply Liang Tao mechanisms, for improving the radiating effect in cabinet.As the air-supply of active wind pushing mechanism
Pipe, active air-supply is carried out by air blower, and air-flow flow to mounting bracket bottom by ajutage, is then flowed out by exhaust vent, right
Radiating fin installed in mounting bracket bottom carries out directly air-supply radiating.The heat that radiating fin distributes electric elements on mounting bracket
Amount is quickly absorbed.Flowed inside and outside blind hole from the air-flow of exhaust vent outflow, improve connecing for radiating fin and air-flow
Contacting surface is accumulated.Air-flow flows out blind hole by through hole, mutual convection current of the air-flow between two arc grooves is realized, so as to further carry
Flow distance of the air-flow between radiating fin high, improves the time of contact of air-flow and radiating fin, improves heat transfer effect
Really.Used as passive wind pushing mechanism, in the presence of ventilating fan, the hot-air in cabinet is constantly discharged, due to the gas of exhaust vent
Stream flow is smaller compared with the flow of ventilating fan, between outside air passes through between air inlet and circular set under pressure differential effect
Gap enters in cabinet, and overall cooling is carried out to cabinet.By setting thermal insulation layer on the outside of ajutage, the gas in ajutage can be made
Stream kept relatively low temperature before exhaust vent is reached.Filter screen can reduce the dust impurity of outside by circular set and air inlet
Between gap enter cabinet.

Specific embodiment
The standardized element used in the utility model can commercially, and shaped piece is according to specification and attached
The record of figure can carry out it is customized, the specific connected mode of each part using bolt ripe in the prior art, rivet,
The conventional meanses such as welding, stickup, will not be described in detail herein.
Reference picture 1-2, one specific embodiment of the utility model includes being provided with several installations in cabinet 1, cabinet 1
Frame 2, is provided with air inlet 3 and air outlet 4 on the cabinet 1, circular set 6, circle set 6 are fixed with by support 5 on air inlet 3
Ajutage 7 is inside plugged with, the air intake of ajutage 7 is connected with air blower 8, and ajutage 7 is arranged on the bottom of mounting bracket 2, blown
Pipe 7 is provided with some groups of exhaust vents 9 towards the side of mounting bracket 2, and the bottom of mounting bracket 2 is provided with and is corresponded with exhaust vent 9
Radiating fin 10, exhaust vent 9 and the gap of radiating fin 10 coordinate, and radiating fin 10 is provided centrally with blind hole 11, radiating fin
10 both sides are provided with arc groove 12, and several through holes 13, adjacent arc are provided between blind hole 11 and arc groove 12
Through hole 13 on groove 12 is staggered, and ventilating fan 14 is provided with air outlet 4.As the ajutage 7 of active wind pushing mechanism, lead to
Crossing air blower 8 carries out active air-supply, and air-flow is flow to the bottom of mounting bracket 2, then flowed out by exhaust vent 9 by ajutage 7, to peace
Radiating fin 10 mounted in the bottom of mounting bracket 2 carries out directly air-supply radiating.Radiating fin 10 distributes electric elements on mounting bracket 2
Heat quickly absorbed.Flowed from the air-flow of the outflow of exhaust vent 9 blind hole 11 is inside and outside, improve radiating fin 10 with
The contact area of air-flow.Air-flow flows out blind hole 11 by through hole 13, realizes that air-flow is mutual right between two arc grooves 12
Stream, so as to further increase flow distance of the air-flow between radiating fin 10, improves connecing for air-flow and radiating fin 10
The time of touching, improve heat-transfer effect.Used as passive wind pushing mechanism, in the presence of ventilating fan 14, the hot-air in cabinet 1 is not by
Disconnected discharge, because the air flow rate of exhaust vent 9 is smaller compared with the flow of ventilating fan 14, outside air leads under pressure differential effect
The gap crossed between air inlet 3 and circular set 6 enters in cabinet 1, and overall cooling is carried out to cabinet 1.The outside of ajutage 7 is enclosed with
Thermal insulation layer 15, thermal insulation layer 15 can make the air-flow in ajutage 7 keep relatively low temperature before exhaust vent 9 is reached, so as to carry
Cooling-down effect for radiating fin 10 high.Filter screen 16 is provided between circle set 6 and air inlet 3, it is possible to reduce outside ash
Trifle in the world matter enters cabinet 1 by the gap between circular set 6 and air inlet 3.
