| Abstract: | An experiment is done on the given parameter heat pip e. According to several figures obtained from the experiment, the analysis was mad e concerning the relation between the inner heat exchange coefficient in heated segment and the temperature difference, the relation between the inner heat exch ange coefficient in condensation segment and the temperature difference, the rel ation between the theoretical heat exchange capacity and real heat exchange capa city, the relation between the heat exchange coefficient and flux and the heat s tream density and et al. These figures are very important for the research of th e thread gravity heat pipe with inner screw. The inner heat exchange coefficient in heated segment is 1.69 more than that in condensation segment when flux 0.00 6?kg/s. |
