Abstract
The utility model relates to a solar energy double-layer through heat collector tube, comprising an external tube and an internal tube. The utility model is characterized in that the length of the internal rube is not less than that of the external tube; the external tube is sleeved outside the internal tube so as to form a double-layer structure; the two end openings of the external tube are sealed with the wall of the internal tube; a gap is left between the inner wall of the external wall and the outer wall of the external wall so as to form a chamber; and the two ends of the internal tube are respectively provided with a water inlet and a water outlet. The utility model is characterized in small heat energy consumption, high heat power efficiency, and fast speed of warming up the water temperature; simultaneously, the water inside the water heater is cycled automatically.
Description
Technical field
The utility model relates to the double-deck center of a kind of solar energy and connects thermal-collecting tube.
Background technology
During existing solar energy utilizes, be single heat collector tube method thermal-arrest, that is, an end of single heat pipe inserts in the glass heat-collecting vacuum tube, accounts for about 80% of heat pipe length overall, is heat absorbing end.The other end is colling end outside glass-vacuum tube, account for about 20% of heat pipe length overall.Colling end inserts in the water tank, finishes indirect heat exchange, that is, the heat that heat pipe is absorbed ceaselessly conducts water in the feed-tank to heat energy indirectly by colling end.It is the heat exchange that utilizes " heat conduction " principle in the calorifics to finish.In utilizing the method for single heat collector tube, following weak point is arranged: the one, it is slow that heat power efficiency is low, heat energy loss is big, water temperature rises.The 2nd, heat transfer area is little, can not circulate automatically.Therefore, utilize scope little.
Summary of the invention
The purpose of this utility model is at the deficiency in the existing single tube heat collecting method, provides the double-deck center of solar energy that a kind of heat energy loss is little, heat power efficiency is high to connect thermal-collecting tube.
The purpose of this utility model realizes with the following methods:
The utility model comprises outer tube, interior pipe, it is characterized in that: the length of interior pipe is not less than the length of outer tube, outer tube sleeve is outside interior pipe, form double-layer sleeve structure, seal between the two-port of outer tube and the tube wall of interior pipe, leave the gap between the inwall of outer tube and the outer wall of interior pipe, form cavity, be respectively equipped with water inlet and delivery port at the two ends of interior pipe.
Above-mentioned outer tube, interior pipe adopt the good metal tube of thermal conductivity, as: copper pipe, aluminum pipe, aluminium-alloy pipe etc., or non-metallic pipe, as: earthenware, carbon element pipe;
Cavity between above-mentioned outer tube and interior pipe is preferably vacuum cavity;
Can inject heat-conduction medium in the cavity between above-mentioned outer tube and interior pipe.
The utility model has the advantages that: heat energy loss is little, heat power efficiency is high, and the water temperature programming rate is fast; Reached the purpose of the automatic circulation of water of water heater simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a horizontal cross-sectional schematic of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises outer tube 3, interior pipe 5, and outer tube 3, interior pipe 5 all adopt the good metal tube of thermal conductivity, as: copper pipe, aluminum pipe, aluminium-alloy pipe etc.; The length of interior pipe 5 is not less than the length of outer tube 3, manage outside 5 in outer tube 3 is enclosed within, form double-layer sleeve structure, seal between the tube wall of the two-port of outer tube 3 and interior pipe 5, leave the gap between the outer wall of the inwall of outer tube 3 and interior pipe 5, form cavity 4, be respectively equipped with water inlet 2 and delivery port 1 at the two ends of interior pipe 5.In order to reach best heat-transfer effect, cavity 4 preferably is evacuated, and should add heat-conduction medium in cavity 4, as: glycerine.
During application, the utility model is connected with water-heater water tank, and water in water tank is entered in this thermal-collecting tube by water inlet 2, carries out heat exchange with interior pipe 5 tube walls, and water heats up the back rising from upper water-out mouth 1 reflow tank of this thermal-collecting tube.Endothermic process: heat up after outer tube 3 absorbs solar thermal energy, the heat-conduction medium that drives in the cavity 4 heats up, after heat-conduction medium heats up, heat conduction and interior pipe 5, in pipe 5 heat up after again with the water generation partition convection current of double-deck thermal-collecting tube central passage (interior pipe), water is heated up flows out from delivery port 1, the cold water that the hot water that delivery port 1 flows out promotes the circulatory system (water tank) moves ahead, enter again in the double-deck thermal-collecting tube from water inlet 2, follow back the purpose that has back and forth realized heat-obtaining like this.
Claims (4)
1, the double-deck center perforation of a kind of solar energy thermal-collecting tube comprises outer tube, interior pipe, it is characterized in that: the length of interior pipe is not less than the length of outer tube, outer tube sleeve is outside interior pipe, form double-layer sleeve structure, seal between the two-port of outer tube and the tube wall of interior pipe, leave the gap between the inwall of outer tube and the outer wall of interior pipe, form cavity, be respectively equipped with water inlet and delivery port at the two ends of interior pipe.
