Abstract
The utility model discloses an improved high-efficiency solar heat collecting tube which comprises a vacuum tube and a heating element; the vacuum tube is in a vacuum structure consisting of inner layered glass and outer layered glass, i.e. an outer layered glass tube and an inner layered heat absorbing tube; the 180-degree pipe wall of the outer layered glass tube is provided with a circular arc-shaped mirror surface; and the spiral heating element is arranged in the vacuum tube. By adopting the structure, circular arc-shaped mirror surface on the outer layered glass tube focuses and reflectslight inwards directly to the inner layered glass tube and the heating element, thereby improving the heat collecting effect. The heating element is spiral, thereby increasing the heated area on theone hand, and receiving the light from different directions on the other hand. Simultaneously, because the thickness of the vacuum layer is increased, the heat loss is low and the heat insulating performance is improved.
Description
Technical field
The utility model belongs to technical field of solar water heaters, is specifically related to a kind of improved efficient solar water heater thermal-collecting tube.
Background technology
At present, the plug-in type solar energy heating tubular construction that generally uses is double-layer glass tube, is evacuated between outer layer glass tube and the inner layer glass tube, inner layer glass tube outer wall painted black, be endothermic tube, absorb luminous energy with the water in the heating tube, utilize vacuum layer to reach the purpose of insulation by endothermic tube.For improving the thermal efficiency of solar energy vacuum tube, constantly the structure of vacuum tube was improved in recent years.A kind of " solar energy heating pipe " disclosed as Chinese patent, its improvements are from descending to having lenticular lens at the solar energy vacuum tube right part, be provided with the METAL HEATING PROCESS rod in the inside of solar energy vacuum tube, the METAL HEATING PROCESS rod is provided with the METAL HEATING PROCESS diaphragm, the upper end of METAL HEATING PROCESS rod is provided with the high temperature heat transfer head, utilizes lenticular lens to focus on, the metallic membrane in the heating, vacuum pipe, with the heating rod heating, add hot water then again.Though this structure has improved the thermal efficiency of vacuum tube, complex structure, parts are done, the assembling processing difficulties, and the manufacturing cost height, influence is promoted the use of.
Summary of the invention
The purpose of this utility model is exactly for overcoming the above problem that existing high-efficiency solar vacuum tube exists, a kind of improved high-efficiency solar thermal-collecting tube is provided, and simple in structure, heat transfer component is few, heat effective, low cost of manufacture.
The purpose of this utility model is achieved through the following technical solutions, this improved high-efficiency solar thermal-collecting tube comprises vacuum tube, heating plate, described vacuum tube is inside and outside layer glass vacuum structure, be outer layer glass tube and internal layer endothermic tube, compare with ordinary vacuum tube, suitably strengthen the diameter of outer layer glass tube, strengthen vacuum layer thickness, 60 millimeters of outer tube diameters, 33 millimeters of diameter of inner pipe, 27 millimeters of vacuum layer thickness are made the circular arc minute surface, to internal reflection on the tube wall of outer layer glass tube 180 degree, described heating plate is positioned at vacuum tube, described heating plate spirality, described heating plate can be selected copper sheet for use, surperficial painted black.
Advantage of the present utility model: the inside reflection ray of the mirror focusing of circular arc type on the outer layer glass tube, directly directive inner layer glass tube and heating plate have improved Heat-collecting effect.Because heating plate is spiral, increased heating surface area on the one hand, can receive light on the other hand from different directions.Simultaneously, owing to strengthened vacuum layer thickness, heat waste is little, has improved heat insulating ability.
