Abstract: A heat exchange apparatus for providing temperature regulation to a person, animal, or inanimate object. The heat exchange device includes an inlet receiving a temperature controlled fluid that is distributed to and passes through a porous layer before being collected and discharged through an outlet. The porous layer is encapsulated in a pair of non-porous layers or sheets. In one embodiment, the pair of non-porous layers extend beyond the boundaries of the porous layer and form a pair of manifolds for distributing the inlet and outlet fluid to and from the porous layer. In one embodiment, the manifolds include flow diverters for distributing the fluid to and from the porous layer. In various embodiments, the heat exchange apparatus is adapted for wrapping around a body part or object, for securing to a seat, and for wearing as a vest or other article of clothing.
