DEVICE FOR DEHUMIDIFYING A CLOSED CASING

WIPO Patent Application WO/2023/135130

A1

The device for dehumidifying (1) comprises a box (3) comprising an inlet (5) communicating with the interior of the closed casing (2) and an outlet (6), a heating module able to be controlled to generate heat, a desiccant (8) configured to adsorb moisture when it is not heated by the heating module (7) and to return adsorbed moisture by desorption when it is heated by the heating module (7), a mobile plug (9) able to be moved to alternately open and close the inlet (5) and the outlet (6), a bias spring (10) configured to move the mobile plug (9) when the heating module (7) does not heat the desiccant (8) and a shape memory alloy spring (11) configured to move the mobile plug (9) when the heating module (7) heats the desiccant (8), said shape memory alloy spring (11) being able to be heated by the heating module (7) at the same time as the desiccant (8). The device for dehumidifying (1) is suited for dehumidifying any type of closed casing, it is cost efficient both in design and in power consumption, and it is easy to implement thanks to its small size and its simple design.
