Abstract

L'invention concerne un procédé de chauffage d’un boîtier (7) renfermant au moins un organe fonctionnel, ledit boîtier comprenant : - au moins une paroi (9) commune avec un réservoir (1) destiné à recevoir un liquide, et - au moins une paroi (11) munie d’un orifice débouchant sur l’extérieur et fermé par une membrane (13) d’équilibrage de pression poreuse à la vapeur d’eau et étanche à l’eau liquide, ce procédé étant remarquable en ce qu’on chauffe le volume intérieur dudit boîtier (7) dans au moins une des situations suivantes : - lorsque ledit réservoir (1) est soumis à une baisse de température autre qu’une baisse de température susceptible de faire geler ledit liquide, - à chaque démarrage d’un véhicule équipé de ce boîtier, - quand on détecte des conditions thermiques susceptibles d’engendrer des condensats dans le volume intérieur dudit boîtier, fermé par ladite membrane.
