Utility model content
Technical problem to be solved in the utility model is just to provide a kind of dehumidification system being applicable to outdoor power cabinet, solves the problem of the effect on moisture extraction difference that current outdoor power cabinet exists.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of dehumidification system being applicable to outdoor power cabinet, semi-conductor dehumidifying module and heating module are installed simultaneously cashier's office in a shop at outdoor power, described semi-conductor dehumidifying module comprises the P-N junction that semiconductor material is formed, fan, condenser and liquid collecting funnel, the P-N junction that described semiconductor material is formed forms thermopair pair, in seal cavity, air-flow is formed by fan, air water molecule is condensate in condenser condenses plate periphery, cold plate is the hydrone condensation in air, collect through liquid collecting funnel and drain into seal cavity outside through flexible pipe, described heating module comprises PTC ceramic heating assembly and is bonded in the ripple aluminum strip on described PTC ceramic heating assembly.
Preferably, also be provided with humiture sensor module and GPRS module, described humiture sensor module gathers the temperature and humidity of air in electric power cabinet, and described GPRS module sends to WEB platform the working condition of the humiture situation in electric power cabinet, semi-conductor dehumidifying module and heating module by GPRS mobile network.
Preferably, at least one of this outdoor power cabinet is provided with heat insulation structure on the surface, and described heat insulation structure comprises hollow layer, is provided with thermofin outside described hollow layer.
Preferably, described hollow layer comprises dividing plate, form hollow structure between described dividing plate and outdoor power cabinet outside surface, be provided with the feet being fixed on outdoor power cabinet outside surface inside described dividing plate, described thermofin is the vacuum heat-insulation plate or the phenolic-aldehyde heat-insulation board that are adhered to dividing plate outside surface.
The utility model is provided with semi-conductor dehumidifying module and heating module cashier's office in a shop at outdoor power simultaneously, therefore, can heat air in electric power cabinet while dehumidification by condensation, in double shield electric power cabinet, equipment is in dry environment all the time, solves the problem of the effect on moisture extraction difference that current outdoor power cabinet exists.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is structural principle block diagram of the present utility model;
Fig. 2 is the heat insulation structure schematic diagram of outdoor power cabinet.
Embodiment
As shown in Figure 1, a kind of dehumidification system being applicable to outdoor power cabinet, comprise arm processor module 1, semi-conductor dehumidifying module 2, heating module 3, humiture sensor module 4, GPRS module 5, note cat 6, WEB platform 7, mobile phone 8, semi-conductor dehumidifying module 2, heating module 3, humiture sensor module 4, GPRS module 5, note cat 6 are all electrically connected with arm processor module 1, GPRS module 5 and WEB platform 7 wireless telecommunications, note cat sends alarm message on the mobile phone 8 of managerial personnel.
Semi-conductor dehumidifying module is based upon on thermoelectric cooling basis, namely the P-N junction that extraordinary semiconductor material is formed is utilized, form thermopair pair, produce Peltier effect, in seal cavity, form air-flow by fan, air water molecule is condensate in condenser condenses plate periphery, cold plate air themperature is down to dew point, the hydrone condensation in air, collects and drain into seal cavity outside through flexible pipe through liquid collecting funnel, continual work like this, thus reach reduction electric power cabinet inner space humidity object.
Heating module utilizes PTC ceramic heating assembly and ripple aluminum strip through the gluing composition of high temperature, and the type ptc heater has the advantage that thermal resistance is little, heat exchange efficiency is high, is the electric heater of a kind of automatic constant-temperature, power saving.An its large outstanding feature is in security performance, there is a temperature artificially set, when its temperature is lower than design temperature, its resistance value can raise with its temperature and diminish, when its temperature is higher than design temperature, its resistance value becomes large with its temperature rising, all can not produce surface " rubescent " phenomenon as electric heating tubing well heater under any applicable cases, thus cause scald, the potential safety hazards such as fire.
Humiture sensor module gathers the temperature and humidity of air in electric power cabinet.GPRS module sends to WEB platform the working condition of the humiture situation in electric power cabinet, semi-conductor dehumidifying module and heating module device by GPRS mobile network.Note cat sends antecedent moisture value on the mobile phone of managerial personnel.Antecedent moisture value normally causes due to the emergency situations such as to intake in semi-conductor dehumidifying module not operation troubles or electric power cabinet, and its numerical values recited sets in arm processor module by WEB platform.WEB platform arranges systematic parameter by GPRS module, comprises the work that the starts or stops threshold values of semi-conductor dehumidifying module and heating module, and the work of artificial force start or stopping semi-conductor dehumidifying module and heating module device.
Above-mentioned functions for can not remote monitoring be carried out to dehumidifier ruuning situation at present, once there is dehumidifier failure problems, just can detectable potential safety hazard when the user such as to only have carry out manual inspection, be provided with remote supervision system.When outdoor power cabinet humidity higher than 80% time to send a warning message managerial personnel's mobile phone and WEB platform; so that the process semi-conductor dehumidifying module not emergency situations such as operation troubles or the interior water inlet of electric power cabinet in time; long-rangely can also carry out optimum configurations to dehumidification module and heating module simultaneously; such as the non-plum rain season of southern china can set to start when electric power cabinet humidity reaches 70% dehumidifying and but do not start heating; but can set electric power cabinet humidity when plum rain season and reach 60% startup dehumidifying simultaneously and heating, object realizes energy-conservation and balance that is proterctive equipment.
As shown in Figure 2, at least one of this outdoor power cabinet 10 is provided with heat insulation structure on the surface, and described heat insulation structure comprises hollow layer, is provided with thermofin 102 outside described hollow layer.Described hollow layer comprises dividing plate 101, hollow structure is formed between described dividing plate and outdoor power cabinet outside surface, be provided with the feet 103 being fixed on outdoor power cabinet outside surface inside described dividing plate, described thermofin is the vacuum heat-insulation plate or the phenolic-aldehyde heat-insulation board that are adhered to dividing plate outside surface.Flow into air in hollow layer heat is taken away fast, thus enhance the radiating effect thermofin of cabinet, can play and prevent the heat transfer process such as direct sunlight, ir scattering, the outside surface of thermofin applies one deck insulating moulding coating, this coating can reflective infrared, far infrared, visible ray, have adhesion jail, anti-filth, heat reflection performance is excellent, further strengthens effect of heat insulation.
