3D POROUS MATERIAL COMPRISING MACHINED SIDE

摘要

3D porous material comprises at least one machined side. The machined side has a solid percentage Ps being (1-Po), said Po is the porosity of the bulk of said 3D porous material and said Ps is within the 99.5% confidence interval. The present invention provides the method of manufacturing such 3D porous material. Preferably, the 3D porous material is open cell metal foam. The present invention also provides use of such open cell metal foam in a heat exchanger. The present invention further provides a heat exchanger comprising open cell metal foam.
