Heat Pipe Solar Collector and Its Sealing Structure

Abstract

The invention discloses a heat pipe solar thermal collector and sealing structures of the heat pipe solar thermal collector. The heat pipe solar thermal collector comprises heat-exchange pipe bodies, the sealing structures and heat pipes. Each heat-exchange pipe body is provided with a containing space, and moreover each heat-exchange pipe body is provided with screw holes and at least one through hole communicating the containing space. Each sealing structure comprises a penetrating connection sleeve and a sealing plug ring, each penetrating connection sleeve comprises a pipe column provided with through holes, the heat pipe penetrates trough the through holes, and a plurality of threads are arranged on the outer edge face of the pipe column and screwed with the screw holes. Each sealing plug ring comprises a ring sleeve and a ring piece, wherein the ring sleeve is sleeved on one heat pipe in a matched mode, the ring piece extends outwards from the outer edge of the ring sleeve, the ring piece is squeezed by one heat-exchange pipe body to abut against the at least one through hole, and one end of each heat pipe is placed in the heat-exchange pipe body through one sealing structure, so that tightness of the combination of each heat-exchange pipe body and the heat pipes is maintained, and the effect of heat exchange is promoted.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to a sealing structure of a heat pipe type solar heat collector. Background technique [0002] At present, in the application of solar radiation heat energy, solar thermal collectors are relatively commercialized and economical products. In order to improve the conversion efficiency of solar radiation thermal energy, heat pipes with excellent thermal conductivity are used in solar thermal collectors. Elements that transfer heat have achieved good results. [0003] Please refer to figure 1 and figure 2 , which are the schematic diagram and cross-sectional view of the current heat pipe solar collector; figure 1 Among them, the sealing structure 1a of the heat pipe type solar heat collector includes a heat exchange pipe body 10a, a plurality of branch pipes 20a inserted into the heat exchange pipe body 10a, and a plurality of heat pipes 30a penetrated into the branch pipes 20a . When the...

Problems solved by technology

[0005] The assembling method of the above-mentioned heat pipe solar collector 1a is not only complicated and time-consuming, but also has the possibility of leakage at the weld. In addition, since these heat pipes 30a do not directly contact the water in the heat exchange pipe body 10a when exchanging heat, Instead, it is indirectly conducted into the heat exchange tube body 10a through the branch pipes 20a, so the heat conduction efficiency is greatly reduced and needs to be improved.
