Abstract
A method for manufacturing a heat exchanger includes: providing a porous material that has a porosity of about 30% to about 80%; forming an oxide layer on a surface of the porous material by heat treating the porous material at a temperature in a range of 600° C. to 900° C. for a time period in a range of 8 hours to 12 hours in air; and integrating the porous material into a cold side flow passage of the heat exchanger.
