TUBE AND TUBE SHEET ASSEMBLY FOR HEAT EXCHANGING BETWEEN TWO DIFFERENT FLUID

摘要

PURPOSE: A heat exchange tube assembly is provided to optimize the heat exchange between different kinds of fluids by allowing the inner and outer tubes to contact one kind of the fluids while blocking from the other. CONSTITUTION: A heat exchange tube assembly(10) comprises a heat exchange tube used for heat exchange between fluids and a tube seat(3) in which both ends of the heat exchange tube are assembled. The heat exchange tube is formed of a double tube consisting of a first heat exchange tube(11) and a second heat exchange tube(12). The tube seat comprises a first joint part(13) in which an end of the first heat exchange tube is installed and a second joint part(14) in which an end of the second heat exchange tube is installed. The first and second heat exchange tubes and the tube seat are assembled by friction fit using expansion.
