Webb3 maj 2014 · Details of evacuated tube heat pipe solar collector. In order to promote thermosyphon flow in the heat pipe solar collector, the outlet of the manifold is tilted about 170 mm higher than the inlet as can be seen in Figure 3. The relative height configuration is shown in Figure 5. Webb12 sep. 2015 · Thermosyphon heat pipe (THP), firstly introduced by Perkins in 1936 [ 4 ], is a two-phase closed heat transfer devices. Its structure is revealed in Fig. 1 schematically. Traditionally, there is no wick structure in such a device, and the evaporation section must be positioned vertically below the condensation section.
