Description
Technical field
The utility model relates to a kind of solar energy and utilizes element, promptly a kind of high-efficiency solar thermal-collecting tube.
Background technology
Existing solar energy heat collection pipe is a double-layer vacuum transparent glass pipe, and the tube wall of its glass tube is double-deck, has higher vacuum between the double-layer tube wall, can adorn heat conducting elements such as heat-conducting medium such as water or heat pipe in the pipe.This thermal-collecting tube is used for solar water heater more, one end of thermal-collecting tube inserts water tank, when sunray shines on the thermal-collecting tube, just can see through double-layer tube wall energy is passed to heat-conducting medium or heat conducting element, because the vacuum layer between double-layer tube wall has good heat-insulating property, the heat energy that heat-conducting medium or heat conducting element are accepted can not scatter and disappear on thermal-collecting tube, and can only transmit in the water tank of an end.Therefore, this thermal-collecting tube has solar collecting performance preferably., it is found that in practice that because the temperature rise of this thermal-collecting tube interior media is evenly slow, power conversion is not smooth, the thermal efficiency is lower, is difficult to satisfy people's demand.
Summary of the invention
The purpose of this utility model provides the higher solar energy heat collection pipe of a kind of thermal efficiency.
Above-mentioned purpose is realized by following technical scheme: develop a kind of high-efficiency solar thermal-collecting tube, this thermal-collecting tube also is a kind of light-transmission tube, and different is: several convex lens are arranged on the tube wall of said thermal-collecting tube, and the focus of convex lens is in pipe.
Said thermal-collecting tube is the dual-layer vacuum glass pipe, and its outer wall is to be formed by several convex lens butt joints.
Said thermal-collecting tube is the dual-layer vacuum glass pipe, and its inner layer tube wall is to be formed by several convex lens butt joints.
Said thermal-collecting tube is the dual-layer vacuum glass pipe, and several convex lens are all arranged on its outer wall and the inner layer tube wall.
Said thermal-collecting tube is the dual-layer vacuum glass pipe, and several convex lens are all arranged on its outer wall and the inner layer tube wall, and the ectonexine convex lens are staggered mutually.
Adopt the high-efficiency solar thermal-collecting tube of technique scheme, can gather the sunray that receives on the interior a plurality of focuses of pipe by top a plurality of convex lens, medium on the focus is heated up rapidly, exchange towards periphery fast again, compare with the mode that existing thermal-collecting tube homogeneous media heats up, the thermal efficiency obviously improves.
Introduce four embodiment below in conjunction with accompanying drawing.

Among the figure as seen: thermal-collecting tube 1, tube wall 2, convex lens 3, vacuum chamber 4, inner tube 5, light beam 6, focus 7, solar water heater 8, water tank 9, upper and lower conduit 10, overflow pipe 11, support 12.
The specific embodiment
First kind of embodiment: as shown in Figure 1, 2, this thermal-collecting tube 1 also is a kind of columned hollow transparent pipe, and its tube wall 2 is to be formed by several convex lens 3 butt joints.The characteristics of convex lens are thick middle, and thin on every side, its form is diversified.What Fig. 3 and Fig. 4 represented is that a kind of cross section is elliptoid convex lens, if collimated light beam 6 is come from a side flat fire, then light converges on the focus 7 of opposite side after by convex lens 3.Because convex lens can converge in Ray Of Light on the focus, it is very fast that the temperature of focus rises.Bigger with the temperature difference on every side, it is also relatively fiercer that heat exchange is carried out.Experiment showed, that convex lens are more much higher than the thermal efficiency of level crossing under same light source irradiation.Its reason is: light is radiated on the medium by level crossing, and medium heats up slowly, and is less with the surrounding medium temperature difference, carries out heat exchange in this case, the rising of intrasystem temperature relative equilibrium, and the chance of radiating part bit-loss heat will increase.And light shines on the medium by convex lens, local heating is very fast, the temperature of each point differs greatly in the system, the thermal source place is awfully hot, other positions are very cool, and the chance of radiating part bit-loss heat will reduce, and heat is concentrated and passed to a bit, the heat that this point obtains is more much bigger than loses heat, helps the accumulation of heat.
Second kind of embodiment: shown in Fig. 5,6, this thermal-collecting tube 1 also is a kind of columned hollow transparent pipe, and its tube wall 2 has inside and outside two-layer, between the two-layer tube wall, is vacuum chamber 4.Outer wall is to be formed by several convex lens 3 butt joints, and inner layer tube wall 5 is common hollow cylindrical.
The third embodiment: shown in Fig. 7,8, this thermal-collecting tube 1 also is a kind of columned hollow transparent pipe, and its tube wall 2 also is inside and outside two-layer, between the two-layer tube wall, also is vacuum chamber 4.Be characterized in, inside and outside two-layer tube wall all is to be formed by several convex lens 3 butt joints, stagger mutually in the convex lens on the inner layer tube wall and the position of the convex lens on the outer wall, space between several convex lens on the center of circle of the convex lens on the inner layer tube wall and the outer wall is relative, can converge the light that the convex outer lens are missed is poly-more like this.
The 4th kind of embodiment: shown in Fig. 9,10, this thermal-collecting tube 1 also is a kind of columned hollow transparent pipe, and its tube wall 2 also is inside and outside two-layer, between the two-layer tube wall, also is vacuum chamber 4.Its inner layer tube wall is to be formed by several convex lens 3 butt joints, and outer wall is common hollow cylindrical.The shape of convex lens 3 such as Figure 11 and shown in Figure 12, one side its cross section is camber line, another side is a straight line, its light also is to converge on the focus 7 of straight line one side.The one side of this convex lens is straight, thereby the difficulty of making is lower.
Figure 13 and Figure 14 have introduced the user mode of this high-efficiency solar thermal-collecting tube.Among the figure as seen, constitute solar water heater 8 by water tank 9, upper and lower conduit 10, overflow pipe 11, support 12, there are many thermal-collecting tubes 1 to be inserted on the water tank 9, when sunray shines on the thermal-collecting tube 1, convex lens 3 are on the poly-focus of converging in pipe of light, media such as interior water of pipe or heat pipe are heated up, in water tank, carry out heat exchange again.
