Description
Technical field
The utility model relates to a kind of dehumidifier, is specifically related to a kind of dewatering type electricity cabinet dehumidifier, is applicable to the electric cabinet dehumidifying of power industry.
Background technology
Present domestic power industry electricity cabinet generally adopts the heater heating to reach effect on moisture extraction, but when heater is worked, the electricity in-cabinet temperature constantly raises, because the moisture that comprises in the higher temperature air rests in the air always, when waiting variation of ambient temperature round the clock, the moisture that comprises in the air is separated out, and bigger air humidity will cause condensation rapidly.Especially switch cabinet wall, terminal board are first-class serious condensation, a harm equipment safety operation.And dewatering type in the market is generally very low except efficient except wet method.The liquefying plant that work is adopted, heat radiation and refrigeration are all undesirable, and efficient is low, the dehumidifier DeGrain.
The utility model content
The purpose of this utility model is to provide a kind of ring main unit dewatering type dehumidifier, adopts the fan fast-refrigerating, and the moisture of liquefaction is discharged electric cabinet, solves condensation problem, when ensureing the electric equipment safe operation, efficiently finishes dehumidifying.
For achieving the above object, the utility model provides a kind of ring main unit dewatering type dehumidifier, comprise housing, described housing front end is provided with the cooling assembly cold junction, the rear end is equipped with a fan, be equipped with on the housing of rear end one with the suitable guard of described fan, the air in the electric cabinet is introduced dehumidifier, fan is fixed on the described guard; Described cooling assembly cold junction back is equipped with the cooling assembly hot junction, and the area of described cooling assembly cold junction is cooling assembly hot junction area half; In the middle of cooling assembly cold junction and cooling assembly hot junction, be equipped with semiconductor chilling plate; Cooling assembly cold junction below is equipped with a catch basin, and described catch basin below connects a drainage pipe.
Further improvement of the utility model is: heat radiating fin structure is all adopted in described cooling assembly cold junction and cooling assembly hot junction, effectively finishes the demand of heat radiation dehumidifying.
Further improvement of the utility model is: described housing is built-in with a control module, by control program with set threshold values and realize control to cooling assembly cold junction, cooling assembly hot junction and fan, the moisture stable in the cabinet in a reasonable range.
The beneficial effects of the utility model are: simple in structure, cheap, easy to operate, and the dehumidification rate height.

Embodiment
In order to deepen understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, this practical protection range is not constituted to limit.
Referring to accompanying drawing 1 and accompanying drawing 2, the utility model proposes a kind of ring main unit dewatering type dehumidifier, comprise housing 1, described housing 1 front end is provided with cooling assembly cold junction 2, and the rear end is equipped with a fan 5, be equipped with on the rear end housing 1 one with the suitable guard of described fan 5, fan 5 all is fixed in housing 1 rear end with guard, air in the electricity cabinet can flow in the dehumidifier by guard, and guard has also guaranteed staff's safety simultaneously, avoids fan to hurt sb.'s feelings and security incident occurs; Described cooling assembly cold junction 2 back are equipped with cooling assembly hot junction 3, and the area of described cooling assembly cold junction 2 is cooling assembly hot junction 3 areas half, the area that is cooling assembly cold junction 2 fin is half of cooling assembly hot junction 3 fin areas, can reduce the cooling assembly cold junction temperature rapidly, improve the operating efficiency of cooling assembly, thereby increase work efficiency and effect on moisture extraction; At cooling assembly cold junction 2 and the cooling assembly hot junction 3 middle semiconductor chilling plates 6 that are equipped with, mode by the fan heat radiation reduces semiconductor chilling plate 6 hot-side temperatures, and semiconductor chilling plate 6 cold junction temperatures also can descend accordingly, reach lower temperature, thereby accelerate cooling assembly cold junction 2 airborne steam is condensed into aqueous water; Cooling assembly cold junction 2 belows are equipped with a catch basin 7, collect condensed aqueous water, and aqueous water is discharged outside the electric cabinet by the drainage pipe 8 that catch basin 7 belows connect.
Described housing 1 is built-in with a control module 4, by control program with set threshold values and realize control to cooling assembly cold junction 2, cooling assembly hot junction 3 and fan 5, the moisture stable in the cabinet in a reasonable range.
When surpassing the threshold values of control module setting, electric cabinet interior humidity just begins dehumidifying work, initiatively the leave heat in cooling assembly hot junction 3 of fan 5, reduce semiconductor chilling plate 6 hot-side temperatures, and the also corresponding decline of semiconductor chilling plate 6 cold junction temperatures, reach lower temperature, thereby reduce the temperature of cooling assembly cold junction 2 rapidly, heat leaves more abundant more rapid, the temperature of cooling assembly cold junction 2 will descend more soon, temperature is just more low, cold like this assembly cold junction 2 just can be condensed into aqueous water to airborne steam, and these aqueous waters fall in the catch basin 7 because of gravity, discharges outside the electric cabinet by drainage pipe 8; When being lower than threshold values, humidity just quits work.Because the area of cooling assembly cold junction 2 is half of cooling assembly hot junction 3 areas, improved the product service behaviour greatly; Effectively the moisture stable in the cabinet in a reasonable range, avoid the condensation problem that causes because of air humidity that the temperature difference produces, thoroughly solve the humidity problem in the electric cabinet, reach protection electric equipment purpose of safe operation.
