ABSTRACT:
A device associates an enclosing capsule in which will be fitted electronic equipment requiring dehumidification, and a medium-to-low voltage converter to recharge electronic equipment. Heat energy released by the coil in the converter will lead to a free thermal exchange of air between the inside and the outside of the capsule, produced by the natural convection from vent holes located in the lower part of the device through which air will be sucked from the outside and vent holes located in the upper part of the device through which warm air thus produced will escape. The circulation of unsaturated warm air around the electronic equipment has the effect of removing the water molecules on the components by saturating the ambient air in the confinement zone, this air being evacuated through vent holes located in the upper part of the device.
