Abstract
The utility model discloses a vacuum heat collecting pipe used for a solar water heater, which is composed of an outer pipe and an inner pipe, wherein a vacuum heat insulating layer is arranged between the outer pipe and the inner pipe. The utility model is characterized in that the pipe wall of the inner pipe is formed by the connection of a plurality of concave-convex surfaces. The vacuum heat collecting pipe with the structure has the advantages the lateral wall of the inner pipe, which is composed of a plurality of concave-convex surfaces can improve the heating area of the inner pipe. In particular, when the pipe wall of the inner pipe is formed by the connection of a plurality of outwards convex circular arc-shaped surfaces, the inner pipe has better heat collecting effect than a common inner pipe because the outwards convex circular arc-shaped surfaces has good heat collecting effect. Consequently, the heat collecting 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; In pipe be 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 promptly cross section of pipe is rounded in it, and its Heat-collecting effect of interior pipe of this shape is not fine.
Summary of the invention
The utility model will provide a kind of Heat-collecting effect better vacuum heat collection pipe.
The technical solution adopted in the utility model is: described vacuum heat collection pipe, constitute by outer tube and interior pipe, and be vacuum heat-insulating layer between outer tube and the interior pipe; Be characterized in: the tube wall of interior pipe is formed by connecting by a plurality of male and fomale(M﹠F)s.
The further technical scheme of the utility model is: the tube wall of interior pipe is formed by connecting by the arc surface of a plurality of outside protrusions.
A kind of further technical scheme of the utility model is: a kind of version of interior pipe is: the tube wall of interior pipe directly is formed by connecting by the arc surface of a plurality of outside protrusions.
The utility model another kind further technical scheme is: the another kind of version of interior pipe is: the tube wall of interior pipe is formed by connecting with the arc surface space that caves inward by the arc surface of outside protrusion.
The utility model has the advantages that: the heating surface area of pipe in the pipe sidewall can improve greatly in being made up of a plurality of male and fomale(M﹠F)s, particularly the arc surface that outwards protrudes has good Heat-collecting effect, thereby just have than the better Heat-collecting effect of pipe in common, thereby improved the collecting efficiency of solar water heater greatly by the interior pipe that the arc surface of a plurality of outside protrusions constitutes.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of vacuum heat-insulating pipe described in the utility model;
Fig. 2 is the A-A cross-sectional view among Fig. 1;
Fig. 3 is the structural representation of the another kind of embodiment of vacuum heat-insulating pipe described in the utility model;
Fig. 4 is the B-B cross-sectional view among Fig. 3.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, be a 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: the tube wall of interior pipe 2 is formed by connecting with the arc surface space that caves inward by the arc surface of outside protrusion.
As shown in Figure 3, Figure 4, 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: the tube wall of interior pipe 2 directly is formed by connecting by the arc surface of a plurality of outside protrusions.
Because outwards the arc surface that protrudes has good Heat-collecting effect, thereby just have the better Heat-collecting effect of interior pipe, thereby can improve the collecting efficiency of solar water heater greatly than common smooth tube wall by the interior pipe that the arc surface of a plurality of outside protrusions constitutes.
In addition, the tube wall of interior pipe also can be formed by connecting by the side of shapes such as concavo-convex gore, trapezoidal faces, and the heating surface area of the interior pipe of these planforms is more a lot of greatly than the heating surface area of the interior pipe of common smooth tube wall, thereby Heat-collecting effect is preferably also arranged; And these variations must belong to protection domain of the present utility model.
Claims (4)
1, vacuum heat collection pipe is made of outer tube and interior pipe, is vacuum heat-insulating layer between outer tube and the interior pipe; It is characterized in that: the tube wall of interior pipe is formed by connecting by a plurality of male and fomale(M﹠F)s.
2, vacuum heat collection pipe as claimed in claim 1 is characterized in that: the tube wall of interior pipe is formed by connecting by the arc surface of a plurality of outside protrusions.
