Abstract
The invention discloses a detachable dustproof apparatus used for a switching power supply suitably used in pager power amplifiers, electric power systems, cluster systems, mobile communication base stations, etc. The detachable dustproof apparatus comprises a dustproof net, a dustproof net framework and clamping grooves. The dustproof net is shorter than the dustproof net framework. The dustproof net is fixed inside the dustproof net framework. The clamping grooves are arranged on the housing parts respectively located over and under a switching power supply wind inlet position. The upper clamping groove and the lower clamping groove are arranged with the groove openings opposed. The length of each clamping groove is equal to that of the housing face. The dustproof net framework and the clamping grooves which are assembled in a matching way are further detachably connected. The dustproof net framework is longer than each clamping groove. The apparatus with a simple structure is cost effective and practical. The apparatus characterized by detachable connection is convenient to install and further convenient to clean and maintain. The detachable dustproof apparatus which is suitably used for satisfying the dustproof demands of conventional common switching power supplies can effectively reduce dust entering the switching power supply when assembled with the switching power supply. The generated faults are reduced. The equipment service lifetime is prolonged. The cost is further lowered. Dustproof effects are achieved. The aim of nipping dust pollution in the bud is further realized.
Description
Technical field
The present invention relates to dust guard, specifically a kind of detachable dust guard for Switching Power Supply, is applicable to the Switching Power Supply that the occasions such as beep-pager power amplifier, electric power system, group system, mobile communication base station use.
Background technology
Switching Power Supply utilizes modern power electronics technology, the time ratio that control switch pipe turns on and off, and maintains a kind of power supply of regulated output voltage, and Switching Power Supply is generally made up of parts such as pulse width modulation (PWM) control IC and MOSFET.Switch element can produce a large amount of heats due to the action of power component in the course of the work, will likely cause Switching Power Supply cisco unity malfunction even to burn if heat can not carry out heat transfer in time.
The excellent of Switching Power Supply heat-conductive characteristic depends primarily on two aspects, is whether device body heat dissipation design is reasonable on the one hand; Whether device have employed effective dust prevention on the other hand.Field practice proves, in the short time, the heat abstractor of device body ensures that Switching Power Supply normally works one of principal element; But the dust guard of Switching Power Supply is the key factor ensureing that Switching Power Supply is run reliably and with long-term.
Due to Switching Power Supply adopt forced air cooling mode to cool in the majority, air streaming potential will be brought in equipment by dust, and Switching Power Supply often should not dismantle cleaning, and excessive dust accumulation, meet wet weather and will cause short circuit or equipment overheat, causing trouble occurs.Current most of occasion, especially for fields such as beep-pager power amplifier, electric power system, group system, mobile communication base stations, the Switching Power Supply used does not install dust guard, or has installed fixed dust guard.Wherein, for the Switching Power Supply of not installing dust guard, after long-time running, seriously cause its bad consequence of dispelling the heat by likely occurring that component surface is dirty; For the Switching Power Supply of installing fixed dust guard, make dust guard surface seriously dirty owing to being difficult to maintenance in charging operation situation, and cause the consequence of improper ventilation, and then will likely cause serious accident.
My unit just once had an equipment investment to run less than just autostop occurring half a year; come to check through technical staff; taking Switching Power Supply apart and find that in it, electronic component buries by dust thickness, is that dust covers and causes power source internal to dispel the heat badly to cause overheated causing through confirming to cause fault.Recently along with ecological deterioration, contamination by dust has been one of main pollutant sources.Therefore, the angle no matter from economy or the angle from reliability, it is all necessary for installing dustproof isolating device additional.
Summary of the invention
The object of this invention is to provide a kind of detachable dust guard for Switching Power Supply, its structure is simple, reasonable in design, and economical and practical, effectively can solve the dust-proof problem of the Switching Power Supply that the occasions such as beep-pager power amplifier, electric power system, group system, mobile communication base station use.
The technical scheme realizing the object of the invention is:
For a detachable dust guard for Switching Power Supply, comprise Air Filter, Air Filter framework and draw-in groove, the length of Air Filter is less than the length of Air Filter framework, and Air Filter is fixed in Air Filter framework; Draw-in groove is arranged on the housing on upper and lower both sides, Switching Power Supply air intake position, and the notch of upper lower bayonet slot is oppositely arranged, and its length is equal with the length in housing face; Air Filter framework is equipped with pocket matches and is connected for detachable, and the length of Air Filter framework is greater than the length of draw-in groove.
The surrounding of described Air Filter is provided with insulation cortex, and insulation cortex is wrapped in the surrounding of the Air Filter be fixed on Air Filter skeleton.Insulation cortex is fixed on dust-proof wire side by available nylon rope or the rope made of hemp.Air Filter can adopt non-conductive and materials such as the good nylon of gas permeability, terylene, polyamide fibre or cotton to make.
Described draw-in groove is fixed by the housing on strong adhesive or the upper and lower both sides of set bolt and Switching Power Supply air intake position, and material therefor can be the good conductor of hardness, toughness and the chemical property such as iron, steel, alloy or artificial synthetic fiber or insulator.
The length of described Air Filter framework is greater than the length of draw-in groove, maintains easily personnel's dismounting.Air Filter framework material therefor can be the good conductor of hardness, toughness and the chemical property such as iron, steel, alloy or artificial synthetic fiber or insulator.
After Switching Power Supply work a period of time, Air Filter surface is seriously dirty, then can dismantle Air Filter framework when equipment does not have a power failure and clear up, insert draw-in groove again after cleaning out, thus maintained switch power source internal is clean, is conducive to its heat exchange.
The invention has the beneficial effects as follows: economical and practical, structure is simple, is detachable connection, easy for installation, is convenient to cleaning and safeguards.Be applicable to the dust-proof demand of existing regular tap power supply, itself and Switching Power Supply be equipped with and can effectively reduce the dust entered in Switching Power Supply, reduce the generation of fault, extension device useful life, cost-saving, realize dust-proof, the object prevented trouble before it happens.
