<p><P>PROBLEM TO BE SOLVED: To provide a gas liquefaction element which can efficiently cool and liquefy flowing gas. <P>SOLUTION: The gas liquefaction element 200a is equipped with: a refrigerant channel 15 in which a refrigerant is made to flow and which has a thermally conductive partition wall 15a; and a gas channel 10 which is provided via the partition wall 15a and in which gas including liquefaction components is made to flow. A thermally conductive porous body 102 which is joined to the partition wall so as to be able to carry out heat exchange and which has continuous air pores 101b where gas is made to flow, is provided in the gas channel. The thermally conductive porous body is equipped with a skeleton 110 which has a thermally conductive shell 110a and a core 110b made of a hollow or/and electrically conductive material. The skeleton 110 constitutes a three-dimensional network structure which is continuous as one body and further a protective covering layer 170 with corrosion resistance is provided on a skeleton surface. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
