Abstract

Le respirateur comprend un masque (1) recouvrant le nez et la bouche, et doté d'une bande (2) le fixant sur la tête. Audit masque (1) est fixé un échangeur thermique (3) réalisé en un matériau hautement thermoconducteur. Ledit échangeur thermique (3) comporte des canaux linéaires de passage (4) orientés le long de l'axe dudit échangeur thermique (3). Le rapport entre le volume total des canaux (4) et le volume total de l'échangeur thermique (3) est compris entre 30 et 80 %. L'air expiré, tandis qu'il passe dans lesdits canaux (4) dudit échangeur thermique (3), restitue sa chaleur à la matière dudit échangeur thermique, et la vapeur contenue dans l'air est partiellement condensée. Le condensat est éliminé à l'extérieur le long des parois desdits canaux (4). L'air expiré est chauffé tandis qu'il passe dans lesdits canaux (4), et ainsi de l'air chaud va jusqu'aux organes respiratoires.
