Abstract:
A heat exchanger for exchanging heat between a fluid and a gas having improved gas-side heat transfer characteristics, said heat exchanger comprising:a housing having a hollow chamber that defines a flow path for gas flowing through said heat exchanger; a conduit extending through said chamber transverse to said flow path of said gas and defining a flow path for fluid flowing through said heat exchanger; a porous heat transfer element in heat conducting contact with said conduit and positioned in said flow path of said gas in said chamber, said porous heat transfer element having a porosity greater than about 25 percent, and a plurality of flow elements extending substantially through said porous heat transfer element and oriented substantially orthogonal to said porous heat transfer element; wherein said conduit extends through said porous heat transfer element.
