Abstract
A novel solar energy heat-collecting pipe comprises a heat-collecting pipe molded by metal pressure casting, fins and reinforcing ribs. Protruded fins are connected to one symmetrical plane of the heat-collecting pipe; a circle in the heat-collecting pipe under the fins is embedded with the reinforcing ribs; and heat absorbing paint is coated on the surfaces of the heat-collecting pipe and the fins; A certain number of protruded fins are arranged on the cylindrical surface of the symmetrical plane of the heat-collecting pipe; fins can not only increase the surface area absorbing sunlight but can effectively decrease the speed of wind flowing through the surface and reduce self heat radiation; and the groove formed by the fins can enable the heat to be repeatedly reflect, thereby further reducing heat radiation. Therefore, the novel solar energy heat-collecting pipe is advantageous by good heat absorbing effect and high heat absorbing efficiency.
Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe, and particularly a kind of solar energy collecting tubes, belong to solar energy hot blast device technical field.
Background technology
Thermal-collecting tube is the key element of solar energy hot blast device, and its main effect is: be used for absorbing the sun energy, the heat of absorption is delivered to corresponding space.At present, the thermal-collecting tube of solar energy hot blast device is all structurally the columned structure led directly to, because periphery is long-pending limited, thereby, its area that effectively absorbs sunlight is also directly by the surface area decision of cylinder, and smooth periphery is under identical air velocity condition in addition, and the flow velocity of its surperficial air is very fast, so the heat of himself is easily taken away by wind-force.So the thermal-collecting tube of existing solar energy hot blast device exists that limit lighting surface is less, self heat is held vaporific defect.
The utility model content
The purpose of this utility model is: a kind of solar energy collecting tubes that a kind of endothermic effect is good, heat absorption efficiency is high is provided, overcomes that the existing daylighting area of existing solar energy hot blast device is less, self heat holds vaporific defect.
The technical scheme that the above-mentioned purpose that realizes the utility model adopts is: a kind of solar energy collecting tubes, it is thermal-collecting tube, fin, the reinforcement that has a die cast metal to be integrated by solar energy collecting tubes, on the surface of thermal-collecting tube symmetrical plane one side, be connected with protruding fin, circle the inside below fin in thermal-collecting tube is inlaid with reinforcement, is coated with heat-absorbing paint on the surface of thermal-collecting tube, fin.
Beneficial effect: the fin that some projections are arranged on the periphery of the utility model due to symmetrical plane one side at thermal-collecting tube, fin has not only increased the surface area that absorbs sunlight, simultaneously, the fin of projection effectively Drag Reducing Flow through surperficial wind speed, reduce distributing of self heat, simultaneously, due to the formed groove of fin, make heat reflection repeatedly therein, reduced further scattering and disappearing of heat, so, the utlity model has the advantage that endothermic effect is good, heat absorption efficiency is high.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present utility model is described further;
Fig. 1 is structure principle chart of the present utility model;
Shown in figure: 1, thermal-collecting tube; , 2, fin; 3, heat-absorbing paint; 4, reinforcement.
The specific embodiment
Thermal-collecting tube 1, fin 2, reinforcement 4 that solar energy collecting tubes has a die cast metal to be integrated, on the surface of thermal-collecting tube 1 symmetrical plane one side, be connected with protruding fin 2, circle the inside below fin 2 in thermal-collecting tube 1 is inlaid with reinforcement 4, is coated with heat-absorbing paint 3 on the surface of thermal-collecting tube 1, fin 2.
