ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a dehumidifier. More particularly, the present invention relates to a dehumidifier for an electronic device such as a computer without a compressor.
A chiller chip needs a transformer to increase a voltage so that an output power of the chiller chip will be increased.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a dehumidifier which is disposed in an electronic device in order to dehumidify an interior of the electronic device without any compressor nor transformer.
Accordingly, a dehumidifier comprises a main casing, a cover plate, a cool air fan, a hot air fan, two aluminum plates, a foamed plastics plate, a plurality of chiller chips, a rectifier, a temperature controller, a filter capacitor, and a voltage converter. The cover plate is fastened on a main frame. The main casing has a round hole, a hot air vent formed on a top portion of the main casing, a plurality of water collecting apertures formed on a bottom of the main casing, two parallel positioning plates, and an upper chamber receiving the rectifier, the temperature controller, the filter capacitor, and the voltage converter. A cover is inserted in the round hole of the main casing. The hot air fan and the aluminum plates are disposed in the main casing. The foamed plastics plate is disposed between the aluminum plates. Each of the aluminum plates has a plurality of radiation fins. The chiller chips are disposed on the aluminum plates. Two temperature sensing rods are disposed on the aluminum plates.
