Title:
BOILING HEAT-TRANSFER MEMBER AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH10121110
Kind Code:
A
Abstract:

To provide a boiling heat-transfer member having a structure to further increase heat-transfer efficiency and its production method.

This boiling heat-transfer member has a metallic porous body obtained by compressing an open-cell metallic sintered compact in the thickness direction on its surface. The powder of metal or metallic alloy is deposited on the surface of the skeleton of a three-dimensional reticular structure as a substrate. The three-dimensional reticular structure coated with the powder is laminated on the surface of a member 130, then heated and burned off. The metal or metallic alloy is sintered to obtain an open-cell metallic sintered compact 110 which is fused to and integrated with the member surface. The formed metallic sintered compact is compressed in the thickness direction to form a metallic porous body 120 having a specified thickness, and a boiling heat- transfer member 100 is produced.
