Abstract
The utility mode provides a dustproof heat-dissipation electric control cabinet which comprises a control cabinet shell, wherein a cable door is arranged at the front side of the shell, an air inlet pipe is arranged at the rear side of the shell and is connected with a compressed air device, the compressed air device consists of a compressed air tank, an air dryer and a semiconductor cooler which are connected in sequence through an aeration pipeline, a heat-absorbing phase-change material plate is respectively arranged on each of the inner walls of the upper side and the rear side of the shell, an axial flow fan is arranged at the upper side of the shell, and a dustproof cover is arranged on the axial flow fan. When the dustproof heat-dissipation electric control cabinet works, an air valve is opened, compressed air enters the control cabinet shell through the air dryer and the semiconductor cooler, so that t a positive pressure can be kept inside the control cabinet, and a dustproof role is played; and cooled air is exhausted from the top of the control cabinet by starting the axial flow fan, and the heat-absorbing phase-change material plates can be used for absorbing heat which cannot be discharged in time through phase change. The dustproof heat-dissipation electric control cabinet integrates dust proofness and heat dissipation and can be used for effectively solving the problem that dust proofness and heat dissipation are difficult to coordinate.
Description
Technical field
The utility model relates to dustproof and cooling technology field, specifically a kind of dust-proof radiating electrical control cabinet of control cubicle.
Background technology
Universal frequency converter ventilates cooling because of need, device is all semi open model, and some main devices of frequency converter especially control board is more responsive to dust, etchant gas etc., therefore use in environment abominable working site to be very easy to break down, thereby need to safeguard continually.According to statistics, the fault that frequency converter occurs is because following dust problem causes more than 90%: 1. all kinds of dust adhere to the surperficial long time integration of radiator fin and stop up the air channel, cause the weak effect temperature rise that cools, and even module damage is shut down in the heat that causes protection; 2. the dust that conducts electricity enters and connects electrical short after the intensive place of bare wire (as between module terminals, on control board) accumulation and cause.
Summary of the invention
For addressing the above problem, the utility model provides a kind of dust-proof radiating electrical control cabinet.
The technical solution of the utility model is: a kind of dust-proof radiating electrical control cabinet, comprise the control cubicle housing, the housing front side is provided with the cabinet door, the housing rear side is provided with air inlet pipe, air inlet pipe is connected with Ignitable gas devices, described Ignitable gas devices is comprised of the compressed air cylinder, empty drier and the semiconductor cooler that connect successively, they are connected by breather line each other, heat absorption phase-change material plate is housed on housing upside and rear side inwall, the housing upside is equipped with axial flow blower, on described axial flow blower, dust cover is installed.
Further, on described breather line, gas switch is housed.
Open gas valve during work, the compressed air in compressed air storage tank enters the control cubicle housing by the air inlet pipe on cabinet after air dryer and peltier cooler, can make like this to keep malleation in control cubicle, plays dustproof effect; Open axial flow blower refrigerating gas discharged from the control cubicle top, and heat absorption phase-change material plate can by phase transformation will be in time the heat absorption of discharge fall.The utility model integrates dustproof and heat radiation, efficiently solves problem dustproof and that heat radiation is difficult to take into account.
