Research Progress of Manufacturing Technology of Enhanced Heat Transfer Structures

Abstract:

In order to transfer heat as much as possible through a unit area in unit time, this paper introduces three enhanced heat transfer structures, namely microchannel, open-celled metal foam and open-celled sintered porous metal. Furthermore, the manufacturing methods of three enhanced heat transfer structures are summarized and comparatively analyzed. Among three enhanced heat transfer structures, open-celled sintered porous metal has the best heat transfer performance, followed by open-celled metal foam and microchannel. While, the sequence of the pressure drop of three enhanced heat transfer structures is in the reverse order. In addition, the manufacturing technology of three enhanced heat transfer structures remain inadequate. Thus, enhanced heat transfer structures with good heat transfer performance and small pressure drop and their corresponding manufacturing technology are the future research direction.
