Patent ID: 7721732

Claim:
A personal heat exchanger device, comprising: a plurality of first elements including: first and second side surfaces; and a desiccant on at least a one of said side surfaces; a plurality of second elements including: first and second side surfaces, wherein each of said first elements is adjacent at least one of said second elements, wherein said second elements further include: protrusions extending from a substantially planar surface of said first side surface by a first distance; and protrusions extending from a substantially planar surface of said second side surfaces by said first distance, wherein a distance between said planar side surfaces of each of said first elements and an adjacent side surface of a second element is about equal to said first distance; an interconnecting member, wherein said first and second elements are positioned spaced apart from and substantially parallel to one another, and wherein said first and second elements are held by said interconnecting member and define at least a first curved surface in a plane that is substantially orthogonal to said first and second side surfaces of said first and second elements.
