Abstract
The utility model discloses a corrugated vacuum heat collecting pipe used for a solar water heater, which is mainly composed of an outer pipe and an inner pipe. A vacuum heat insulation layer is arranged between the outer pipe and the inner pipe. The utility model is characterized in that concave convex corrugation is arranged on the pipe wall of the inner pipe, and an inner lining pipe is also arranged in the inner pipe. The open end of the inner lining pipe is connected with the bottom of the inner pipe, and an inner cavity of the inner lining pipe is mutually isolated with an inner cavity of the inner pipe. The utility model has the advantages that because the pipe wall of the inner pipe is provided with the concave convex corrugation, the heating area of the inner pipe can be added. In particular that a circular arc-shaped surface which is outwards convex is provided with good effect of heat collection, and the inner pipe with the structure has better heat collection effect. In addition, after the inner lining pipe is arranged in the inner pipe, storing water in the inner pipe can be reduced. Then, the utilization rate of water resources can be improved and the heating time of water in the inner pipe can be shortened. Consequently, the heat collection efficiency of the solar water heater can be improved.
Description
Technical field
The utility model relates to the vacuum heat collection pipe that is widely used on the solar water heater.
Background technology
Vacuum heat collection pipe is the heat collecting element in the solar water heater, and the vacuum heat collection pipe that uses mainly is made of outer tube and interior pipe at present, is vacuum heat-insulating layer between outer tube and the interior pipe; The intake-outlet of interior pipe is connected with water tank in the solar water heater.Its temperature can raise after water in the interior pipe was subjected to solar radiation, and can form convection current with the water in the water tank, thereby the water in the water tank is heated.Present its inner pipe wall of employed vacuum heat collection pipe is smooth cylinder, and its heating surface area of interior pipe of this shape is less, and Heat-collecting effect is not fine; In addition, because the caliber of interior pipe is thicker relatively, thereby the water of storing in the interior pipe is more, this part water can not enter into water tank and be utilized by people, and this has reduced the utilization rate of water resource on the one hand, on the other hand, because the water in the interior pipe is more, thereby the time of heating is just longer, and the thermal efficiency is just lower.
Summary of the invention
The utility model will provide the back-shaped formula vacuum heat collection pipe of ripple that a kind of Heat-collecting effect is better, water utilization rate is higher.
The technical solution adopted in the utility model is: the back-shaped formula vacuum heat collection pipe of described ripple, mainly constitute by outer tube and interior pipe, and be vacuum heat-insulating layer between outer tube and the interior pipe; Be characterized in: have the ripple of concaveconvex shape on the tube wall of interior pipe, and also be provided with an internal lining pipe in interior pipe, the openend of internal lining pipe is connected with the bottom of interior pipe, and is isolated mutually between the inner chamber of internal lining pipe and the inner chamber of interior pipe.
The further technical scheme of the utility model is: the inner chamber of internal lining pipe is connected with vacuum heat-insulating layer.
A kind of further technical scheme of the utility model is: the ripple of described concaveconvex shape is formed by connecting by the arc male and fomale(M﹠F).
The utility model another kind further technical scheme is: the ripple of described concaveconvex shape is formed by connecting by trapezoidal male and fomale(M﹠F).
The utility model has the advantages that: owing to have the ripple of concaveconvex shape on the tube wall of interior pipe, thereby the heating surface area of pipe in can increasing greatly, particularly the arc surface that outwards protrudes has good Heat-collecting effect, thereby the interior pipe of this structure compares with pipe in the common smooth cylinder, just has better Heat-collecting effect; And, after in interior pipe, being provided with internal lining pipe, the space of tube cavity in can significantly reducing, just significantly reduced the water in the interior pipe, this has not only improved the utilization rate of water resource greatly, and shortened heat time heating time of interior Guan Zhongshui, thereby improved the collecting efficiency of solar water heater greatly.

Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, be a kind of embodiment of the back-shaped formula vacuum heat-insulating pipe of ripple described in the utility model, its structure is: the back-shaped formula vacuum heat collection pipe of described ripple, mainly constitute by outer tube 1 and interior pipe 2, and be vacuum heat-insulating layer 3 between outer tube 1 and the interior pipe 2; Be characterized in: on the tube wall of interior pipe 2, have the ripple that is formed by connecting by the arc male and fomale(M﹠F), and in interior pipe 2, also be provided with an internal lining pipe 4, the openend of internal lining pipe 4 is connected with the bottom of interior pipe 2, and is isolated mutually between the inner chamber of the inner chamber of internal lining pipe 4 and interior pipe 2; In the present embodiment, the inner chamber of internal lining pipe 4 is connected with vacuum heat-insulating layer 3.
As Fig. 4, Fig. 5, shown in Figure 6, be the another kind of embodiment of vacuum heat-insulating pipe described in the utility model, its structure is: described vacuum heat collection pipe, constitute by outer tube 1 and interior pipe 2, be vacuum heat-insulating layer 3 between outer tube 1 and the interior pipe 2; Be characterized in: on the tube wall of interior pipe 2, have the ripple that is formed by connecting by trapezoidal male and fomale(M﹠F), and in interior pipe 2, also be provided with an internal lining pipe 4, the openend of internal lining pipe 4 is connected with the bottom of interior pipe 2, and is isolated mutually between the inner chamber of the inner chamber of internal lining pipe 4 and interior pipe 2; In the present embodiment, the inner chamber of internal lining pipe 4 is connected with vacuum heat-insulating layer 3.
In actual use, the same with vacuum heat collection pipe in the traditional solar water heater, the intake-outlet 5 of interior pipe 2 is connected with the water tank in the solar water heater.
From the above mentioned as can be known, owing to have the ripple of concaveconvex shape on the tube wall of interior pipe 2, thereby pipe 2 heating surface area in can increasing greatly, particularly the arc surface that outwards protrudes has good Heat-collecting effect, thereby the interior pipe 2 of this structure compares with pipe in the common smooth cylinder, just has better Heat-collecting effect; And, after in interior pipe 2, being provided with internal lining pipe 4, the space of tube cavity in can significantly reducing, just significantly reduced the water in the interior pipe 2, this has not only improved the utilization rate of water resource greatly, and shortened heat time heating time of water in the interior pipe 2, thereby improved the collecting efficiency of solar water heater greatly.
In addition, described bellows-shaped also can be formed by connecting by the triangle male and fomale(M﹠F)---and be the indention bellows-shaped, perhaps described bellows-shaped is made of the thread-shaped male and fomale(M﹠F) on similar bolt surface, and perhaps the male and fomale(M﹠F) hybrid combining by several shapes forms; And above-mentioned bellows-shaped is all arranged on the axial cross section of interior pipe and is formed bellows-shaped in the utility model, can also form bellows-shaped on the radial cross-section of interior pipe equally in addition, the interior pipe of these structures also has than the better Heat-collecting effect of pipe in the common smooth cylinder; And similar these variations must belong to protection domain of the present utility model.
