Abstract
The invention discloses a safe electric control cabinet applied to dangerous areas. The safe electric control cabinet comprises an electric control cabinet body, a cold air inlet filtering net, a sealed air channel and a miniature explosion-proof fan, wherein the cold air inlet filtering net is arranged on one side of the upper part of the electric control cabinet body; the miniature explosion-proof fan is arranged on one side of the lower part of the electric control cabinet body; and both ends of the sealed air channel are connected to the cold air inlet filtering net and the miniature explosion-proof fan. The safe electric control cabinet has a simple structure and can dissipate heat for electric components which are operated in inflammable and explosive areas.
Description
Technical field
The present invention relates to a kind of electric control cabinet, a kind of safety-type electrical equipment control cubicle that is applied to the deathtrap of saying so more specifically.
Background technology
Because the propelling that the whole world " Montreal Protocol " and ODS transform substitutes the floride-free household electrical appliances of original freon foam production, protection atmospheric ozone layer at household electric appliances extensive use pentamethylene.Pentamethylene is a kind of alkanes chemical raw material, has physical characteristics such as inflammable, explosive, volatile.So the control system of in the regional space that uses pentamethylene, using must possess good security performance and explosion-proof performance; It seems that to common electrical equipment control cabinet electrical equipment control cabinet has the heat radiation defective usually: the inner electric elements of electrical equipment control cabinet need heat radiation at work, and general electrical equipment control cabinet all must be offered ventilating opening; It is low that the ventilation of offering according to the mode of hot and cold air flow is necessary for inlet; Outlet is high, guarantees that cold air gets into from electrical equipment control cabinet bottom, discharges from top behind the cooling electric elements; But pentamethylene vapor density ratio air is high; Inflammable pentamethylene steam is in air lower floor, and electrical equipment control cabinet can inhaled loop pentane steam when sucking cold air down, so just has the danger of detonation; If simply change into from the bottom discharge of electrical equipment control portion's suction cashier's office in a shop cold air and do not meet the rule that the heat radiation hot-air makes progress again.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of simple in structure, can be explosion-proof and the safety-type electrical equipment control cubicle that is applied to the deathtrap of heat radiation.
The technical scheme that the present invention solves above-mentioned technical problem is: comprise electric control cabinet body, cold air inlet screen pack, sealing air channel and small-sized explosion-proof fan; Described cold air inlet screen pack is installed in electric control cabinet upper part of body one side; Described small-sized explosion-proof fan is installed in bottom one side of electric control cabinet body, described seal channel two ends be connected on the cold air inlet screen pack with small-sized explosion-proof fan on.
Owing to adopt technique scheme; Technique effect of the present invention is: owing to adopted cold air is blown into the sealing air channel from the cold air inlet screen pack on electric control cabinet top; Cold wind gets into small-sized explosion-proof fan through seal channel, and small-sized explosion-proof fan drives cold wind and in electric control cabinet, rises, and takes away the heat that electric elements give out in the control cubicle; Thereby avoided sucking inflammable and explosive pentamethylene, played effect explosion-proof and heat radiation.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
As shown in Figure 1; The present invention includes electric control cabinet body 1, cold air inlet screen pack 2, sealing air channel 3 and small-sized explosion-proof fan 4; Described cold air inlet screen pack 2 is installed in top one side of electric control cabinet body 1; Described small-sized explosion-proof fan 4 is installed in bottom one side of electric control cabinet body 1, described seal channel 3 two ends be connected on the cold air inlet screen pack 2 with small-sized explosion-proof fan 4 on.
Operation principle of the present invention is: during work; Cold air gets into sealing air channel 3 from the cold air inlet screen pack 2 on electrical equipment control cabinet body 1 top; And through the small-sized explosion-proof fan 4 of sealing air channel 3 entering; Small-sized explosion-proof fan 4 drive cold wind rise in cabinet and take away the heat that electric elements distribute in the electric control cabinet, reach electric elements heat radiation and explosion-proof effect in the hazardous area.
