Heat Transfer Properties of Porous Surface Tubes Under the Vacuum Conditions
In this paper, the heat transfer enhancement about sintered porous surface tubes which were applied in adsorption refrigeration vaporizer had been studied under the vacuum conditions. The result showed that the heat transfer coefficient of sintered porous surface tubes was higher than that of smooth tubes. Further, the heat transfer enhancement factor of sintered porous surface tubes increased from 1.2 to 5.0 with the increase in pressure. Also, the research showed that both the porous tubes and the smooth tubes had tube bundle effect in the condition of vacuum, and the heat transfer performance of porous tubes was significantly higher than smooth tubes.
