Description
Technical field
The present invention relates to the electronic dehumidifying device in a kind of terminal box, be mainly used in to dehumidifying in terminal box.
Background technology
Current domestic power industry electricity cabinet generally adopts heater heating to reach effect on moisture extraction, but in the time that heater is worked, electricity in-cabinet temperature constantly raises, because the moisture comprising in higher temperature air rests in air always, in the time of the variation of ambient temperature such as round the clock, the moisture comprising in air is separated out, and larger air humidity will cause rapidly condensation, forms condensation chamber.Especially switch cabinet wall, terminal board are first-class serious condensation, a harm equipment safety operation.And dewatering type in the market except wet method except efficiency generally very low.The liquefying plant that work adopts, heat radiation and refrigeration are all undesirable, and efficiency is low, dehumidifier DeGrain.
Summary of the invention
The present invention is low in order to solve dehumidification rate in current terminal box, the problem of weak effect, electronic dehumidifying in a kind of terminal box device is provided for this reason, comprise cabinet 1, in described cabinet 1, be provided with and control mainboard 2, in described cabinet 1, also erect and have a baffle plate 4, baffle plate 4 is fixed between the two side of cabinet 1, and with the bottom vertical of cabinet 1, described control mainboard 2 is arranged on cabinet 1 bottom of baffle plate 4 one sides, the opposite side of baffle plate 4 is fixed with a fan 5, the top of described baffle plate 4 is also provided with a semiconductor cooler 6, the upper surface of semiconductor cooler 6 is provided with cooling piece 7, lower surface is provided with fin 8, described cooling piece 7 is connected with scupper hose, described semiconductor cooler 6 and fan 5 are all electrically connected with controlling mainboard 2, control mainboard 2 and are provided with temperature sensor 9 and humidity sensor 10, are also connected with power supply.
Electronic dehumidifying device in terminal box of the present invention, is also respectively equipped with the first air intlet 11 and the second air intlet 12 on the cabinet sidewall of described semiconductor cooler 6 both sides.
Electronic dehumidifying device in terminal box of the present invention, described semiconductor cooler 6 is positioned at the top of fan 5, and fan blows to fin, lowers the temperature to fin.
Electronic dehumidifying device in terminal box of the present invention, leaves space between described baffle plate 4 and the bottom of cabinet 1, further increases cross-ventilation, accelerates cooling to fin.
The invention has the beneficial effects as follows:
The present invention can be effectively the moisture stable in cabinet between 40%～55%, avoid the situations such as the electric leakage causing because of condensation, protected the safe operation of electric equipment, and dehumidification rate is high, effect on moisture extraction is good.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is right view of the present invention.
Embodiment
Disclosed all features in this specification, or step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification, unless narration especially all can be replaced by other equivalences or the alternative features with similar object.,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
Electronic dehumidifying device in terminal box as depicted in figs. 1 and 2, comprise cabinet 1, the both sides of cabinet are respectively equipped with the first air intlet 11 and the second air intlet 12, in described cabinet 1, be provided with and control mainboard 2, also perpendicular in described cabinet 1 have a baffle plate 4, and baffle plate 4 is fixed between the two side of cabinet 1, with the bottom vertical of cabinet 1, and and leaving space between the bottom of cabinet 1, the design of space and two air intlets can produce cross-ventilation.Described control mainboard 2 is arranged on cabinet 1 bottom of baffle plate 4 one sides, and control on mainboard 2 and be also provided with temperature sensor 9, humidity sensor 10 and power supply, be fixed with a fan 5 at the opposite side of baffle plate 4, the top of fan 5 is provided with a semiconductor cooler 6, semiconductor cooler 6 is fixed on baffle plate 4 tops, described semiconductor cooler 6 and fan 5 are all electrically connected with controlling mainboard 2, control mainboard 2 fan 5 and semiconductor cooler 6 are controlled.Wherein, the upper surface of this semiconductor cooler 6 is provided with cooling piece 7, and lower surface is provided with fin 8, and described cooling piece 7 is connected with scupper hose.
Wherein, temperature sensor is for detection of the temperature in when work, and humidity sensor is for detection of humidity.The threshold values that the control module of controlling on mainboard is arranged to humidity is between 40%～55%, when in humidity sensor detects cabinet, humidity exceedes 55%, controlling mainboard control fan and semiconductor cooler starts working, when lower than 40% time, control mainboard control fan and semiconductor cooler and stop dehumidifying.
Described the first air intlet is positioned at fan side, and in the time that humidity exceedes 55%, fan is lowered the temperature to the fin on semiconductor cooler automatically, make the also corresponding decline of temperature of cooling piece, reach lower temperature, cooling piece is condensed into aqueous water steam, and discharges from scupper hose.And the second air intlet is positioned on the cabinet wall on the first air intlet opposite, and on the side of cooling piece, air with humidity enters from the second air intlet, direct cooled of moisture is wherein condensed into water and is excluded, air is dried, dried air can drive condensation accumulated water to accelerate, toward dirty, to improve condensation effect on the one hand; Owing to first passing through cooling piece, temperature is lower, then pumps to fin by fan on the other hand, can improve the heat radiation to semiconductor cooler.Cooling piece continues steam is condensed into water and gets rid of outside cabinet, and in humidity sensor detects cabinet, humidity lower than 40% time, is controlled mainboard control fan and semiconductor cooler and stopped dehumidifying.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
