Heat-conducting structure of heat-tube type all-glass solar vacuum heat-collection pipe

A heat transfer structure of thermo tube all-glass solar vacuum collector tube comprises at least one thermo tube in which the evaporation section is inserted and sealed inside a vacuum glass tube. A heat transfer fin is arranged between the inner walls of the thermo tube and the vacuum glass tube, which is a flake good heat conduction body snaked into a ring with a certain flexible shoring tension. The evaporation section of the thermo tube is clamped between two layers flake good heat conduction bodies, and both sides are in the formation of a contact along the axial direction. The simplest structure and the techniques with easiest installation can be utilized in the utility model, thereby the better heat transfer efficient can be achieved.
