Description

Air-cooled electronic dehumidifier with return fan cover and porous damping wind deflector

Technical Field

The utility model discloses be applied to the electronic type dehumidifier field, involve a change and adjust the dress system part of blowing to dehumidifier radiator and condenser wind direction, amount of wind and wind temperature.

Background

The principle of the electronic dehumidifier is that a semiconductor refrigerating sheet is electrified to work, the refrigerating sheet is provided with a cold end face and a hot end face, the hot end is tightly attached to a radiator to discharge heat during working, so that a condenser tightly attached to the cold end is cooled rapidly, when external humid air is sucked by a shaft flow fan and passes through the low-temperature condenser, moisture in the air is condensed on the condenser due to large temperature difference, flows into a water collecting tank under the action of gravity and is discharged from a water discharging pipe.

Because a compressor is not adopted, the electronic dehumidifier can be made smaller and more exquisite, and has the advantages of small volume, low power consumption, light weight, no vibration, low noise, long service life, simple installation, no maintenance and the like, thereby being widely applied to various industrial switch power distribution cabinets and household applications.

The amount of dehumidification and the dehumidification effect of the electronic dehumidifier mainly depend on the following factors: 1. the power of the refrigeration plate. 2. The heat dissipation and ventilation performance of the hot end is good. 3. The temperature difference between the condenser at the cold end and the humid air is large (the larger the temperature difference, the more likely condensate is produced). 4. The ambient humidity is relatively high and the moist air is allowed to flow continuously through the condenser. 5. The volume of the dehumidified cabinet is matched with the power of the dehumidifier and is relatively sealed.

Because the electronic dehumidifier is generally designed to have a compact structure and a small volume, only one fan is generally selected in the small dehumidifier, and the fan has the following functions: 1. the air quantity is large enough to radiate the heat of the radiator at the hot end. Because the volume of the dehumidifier is small, the radiator is not too large, and the air volume of the configured fan is relatively large to ensure good radiating effect. 2. The fan is with the humid air suction in the rack to the dehumidifier in, the air current carries out the condensation through the cold junction, gets rid of the moisture content in the air, discharges dry air simultaneously, and the purpose of the internal dehumidification of cabinet is reached in the circulation of this way repeatedly. For the condenser, since it takes time to exchange heat and cold with the moist air to achieve the condensation effect, the requirement for the air volume requires a smaller flow rate and a slower wind speed. 3. Since moisture generated after condensation naturally flows into the water collecting tank by gravity, the wind direction at one end of the condenser should be downward, so that the wind direction needs to be changed. 4. Because the power of the cabinet electronic dehumidifier is generally smaller and the minimum power is only 10W, the air quantity can be gathered in the cabinet to form a reasonable air duct so as to achieve a better condensation and dehumidification effect.
