Abstract
The utility model relates to an air-conditioning device of a power distribution cabinet, which comprises a radiator and a fan arranged on the side surface of the radiator. The front air inlet of the fan is provided with a detachable filter screen. The radiator is provided with a mounting bracket. The air-conditioning device is low in cost, long in service life, green and environment-friendly, safe and reliable. When a positive temperature coefficient (PTC) heater emits heat, no open fire exists. Thus, combustion fire hazards are eliminated. Meanwhile, since the device adopts the heated air circulation mode, the device is high in heating and dehumidifying efficiency, low in power consumption and convenient in installation. Therefore, the reliability and the safety of the power distribution operation are greatly improved.
Description
Technical field
The utility model relates to a kind of conditioner, particularly a kind of power distribution cabinet conditioner.
Background technology
At present, power distribution cabinet in the employing of all kinds of buildings uses more and more extensive, mostly adopt the metal material manufacturings such as steel, aluminium due to power distribution cabinet, season and low temperature variation due to the external world, power distribution cabinet is arranged on basement more, physical features is lower, and because body of wall exists crack, hole infiltration, the situations such as high temperature plum rain season air humidity increasing cause indoor ponding or air humidity to approach even over saturation condition.On the other hand, outside air defense basement, the soil moisture is lower than body of wall temperature and indoor temperature, and the body of wall temperature is lower than indoor temperature.According to thermal conductivity law, add that concrete conductive coefficient is higher, so damp-heat air easily forms the moistureproof dewfall phenomenon of basement when touching colder interior metope.Damp-heat air touches colder power distribution cabinet (dish, case) metal shell, during lower than the dew point temperature of air, easily forms dewfall when metallic surface temperature in the metal surface, produces condensate.Appearance is joined
The formation of electricity cabinet dewfall may cause serious fault or the short circuit of rack utensil normally to move.
The utility model content
In order to overcome the deficiency of existing apparatus, the utility model provides a kind of power distribution cabinet conditioner be used to preventing the rack condensation.
The technical scheme that its technical problem that solves the utility model adopts is: the power distribution cabinet conditioner, comprise radiator, and also comprise blower fan, the radiator side is provided with blower fan, and the anterior air inlet of blower fan is provided with the removable filter net, and radiator is provided with mounting bracket.
Be provided with PTC heating element and temperature sensor in radiator.
Heating element of the present utility model connects the 220V AC power, and temperature sensor connects controller, can control the cabinet temperature and humidity of power distribution cabinet, outdoor box change etc., realizes the reliability service of communication apparatus.
The beneficial effects of the utility model are: cost is low, long-life, safety, environmental protection, safe and reliable, the PTC adstante febre is not rubescent, the flames of anger, without the burning disaster hidden-trouble, adopt hot air circulation, heating and dehumidification efficient is high, power consumption is little, easy for installation, can greatly improve distribution reliability of operation and fail safe.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is enforcement illustration of the present utility model.
Parts and numbering in figure:
The 1-radiator; The 2-blower fan; The 3-screen pack; The 4-support.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 1～Fig. 2, the power distribution cabinet conditioner comprises radiator 1, also comprises blower fan 2, and radiator 1 side is provided with blower fan 2, and the anterior air inlet of blower fan 2 is provided with removable filter net 3, and radiator 1 is provided with mounting bracket 4.
Be provided with PTC heating element and temperature sensor in radiator 1.
Implementation process: this power distribution cabinet conditioner too high trestle 4 is installed on rack or cabinet inside, the PTC heating element connects the 220V AC power, temperature sensor is connected to controller, can pass through the controller design temperature, the operation of control heater and blower fan 2, also can carry out the adjustment of heating power, reach best anti-condensation and effect on moisture extraction, add thermal insulation properties more reliable, owing to adopting hot air circulation, outlet temperature continues for a long time 40 ℃ ~ 60 ℃ left and right, and air temperature modification is steady.In cabinet, bulk temperature is relatively even; Blower fan 2 is furnished with screen pack 3, and detachable dedusting keeps cleaning in cabinet, extends the useful life of other device in cabinet.
