Abstract
Method of and apparatus for exchanging heat between two fluids wherein a core member is composed essentially of vermicular expanded graphite which has been compressed primarily along one axis and heat is exchanged in the core member between the two fluids along an axis normal to the primary axis of compression of the core member.
Claims1
A heat exchanger comprising a cylindrical core member composed of a plurality of circular plates, each plate being composed of vermicular expanded graphite which has been compressed along an axis normal to the radius of said plate to a density of at least 100 pounds per cubic foot, means for compressing said plates in a fluid tight relationship against one another and along an axis normal to the radius of said plates, means for passing a first fluid in contact with said core member, and means for passing a second fluid through said core member in separate but heat exchanging relationship with said first fluid, the axis of heat exchange between the first and second fluids being along the radius of said plates.
