Abstract

A heat exchanger includes at least one hot fluidflow channel comprising a first plurality of open cell porous elements having first gaps therebetween for flowing a hot fluid in a flow direction and at least one cold fluid flow channel comprising a second plurality of open cell porous elements having second gaps therebetween for flowing a cold fluid in a countercurrent flow direction relative to the flow direction. Ther thermal conductivity of the porous elements is at least 10 W/m*K. A separation member is interposed between the hot and cold flow channels for isolating flow paths aossciated with these flow channels. The first and second plurality of porous elements at least partially overlap one another to form a plurality of heat transfer pairs which transfer heat from respective ones of the first porous elements to respective ones of the second porous elements through the separation member.
