Abstract
The utility model relates to a novel concentrating glass vacuum solar collector tube, comprising an inner bag, an outer layer and a baffle-board, which is characterized in that compared with the prior glass vacuum solar collector tube, the utility model enlarges the space of the vacuum layer, and a hyperboloid baffle-board or a compound paraboloid baffle-board is arranged in the vacuum layer. The solar collector tube has the advantages of high heat-collecting efficiency and lighting ratio, in addition, the baffle-board has no dust stratification.
Description
The utility model relates to a kind of glass vacuum heat collection tube of solar energy.
The inner bag caliber of existing glass vacuum solar collector tubes is slightly less than outer field caliber, and promptly the clearance distance of vacuum layer is little.Solar water heater by some glass heat-collecting vacuum tubes side by side in a row and reflecting plate, water tank be formed by combining.Certain spacing is arranged between the thermal-collecting tube.Be mapped on the thermal-collecting tube in a row side by side with different angles from morning to dusk sunshine.Wherein partly sunlight is mapped on the thermal-collecting tube inner bag outer surface through transparent thermal-collecting tube skin, is absorbed by the coating for selective absorption that is coated with on the thermal-collecting tube inner bag surface; Another partly sunlight be mapped to thermal-collecting tube reflecting plate behind by the gap between the thermal-collecting tube, thereby reflex to glass heat-collecting vacuum tube inner bag rear face and be absorbed.The light that reflecting plate reflected have again part by the gap directive environment between the thermal-collecting tube by the absorption of air in the environment.
The shortcoming of above-mentioned existing glass heat-collecting vacuum tube is: (1) some sunshine can not be utilized owing to reflex to environment space.(2) since reflecting plate below thermal-collecting tube, easily dust stratification and don't easy cleaning and cause reflection efficiency low, thus influence the thermal efficiency of thermal-collecting tube.
The purpose of this utility model is: a kind of converging vacuum glass soalr energy heat-collecting pipe of novelty is provided, has not multiple advantages such as dust stratification dirt of collecting efficiency height, reflector.
The technical solution of the utility model is: (1) enlarges the space of vacuum layer.Thermal-collecting tube internal layer and outer field spacing have promptly been strengthened.(2) light collecting reflecting plate of the hyperboloid of particular design or composite parabolic reflecting plate are placed in the vacuum layer of thermal-collecting tube.The sunlight of different angles directive hyperboloid reflecting plate or composite parabolic reflecting plate is all absorbed by the lip-deep coating for selective absorption of thermal-collecting tube inner bag through reflection or refraction for several times.The gap that the solar water heater that converging vacuum glass soalr energy heat-collecting pipe of the present utility model is formed is arranged between the thermal-collecting tube in a row is very little.The minute surface of reflecting plate upwards.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the front view of the utility model solar energy heat collection pipe embodiment 1;
Fig. 2 is the vertical view of the A-A section of the utility model solar energy heat collection pipe embodiment 1.
Fig. 3 is the front view of the utility model solar energy heat collection pipe embodiment 2.
Fig. 4 is the vertical view of the A-A section of the utility model solar energy heat collection pipe embodiment 2.
Embodiment 1:
The utility model converging vacuum glass soalr energy heat-collecting pipe first embodiment as shown in Figure 1 and Figure 2 comprises hyperboloid reflecting plate 1, thermal-collecting tube inner bag 2, vacuum layer 3, thermal-collecting tube skin 4.
The outer surface of thermal-collecting tube inner bag 2 scribbles coating for selective absorption, but 2 retainings of thermal-collecting tube inner bag or insertion metal sleeve; The concave surface of hyperboloid reflecting plate 1 is made minute surface, and the width of hyperboloid reflecting plate 1 equates with the inner diameter of thermal-collecting tube skin 4 and is close on the inwall of thermal-collecting tube skin 4.
S1, S2, S3 represent that different angles penetrate the sunshine on the minute surface of hyperboloid reflecting plate 1.The outer surface at thermal-collecting tube inner bag 2 is penetrated in the reflection of light process hyperboloid reflecting plate 1 minute surface or refraction back homopolymerization, thereby being painted on coating for selective absorption on the outer surface of thermal-collecting tube inner bag 2 absorbs and transfers heat energy to, because of hyperboloid reflecting plate 1 is installed in the vacuum layer 3, so dust stratification dirt not, the reflectivity height.
Embodiment 2:
The utility model second embodiment as shown in Figure 3, Figure 4, its basic structure is identical with first embodiment, its difference be embodiment 1 thermal-collecting tube reflecting plate be the hyperboloid shape, and the converging vacuum glass soalr energy heat-collecting pipe of embodiment 2 in reflecting plate be the composite parabolic shape.S1, S2, S3 represent that different angles penetrate the sunshine on the minute surface of composite parabolic reflecting plate 1.The reflection of light process composite parabolic reflecting plate 1 minute surface or refraction back homopolymerization are penetrated at the outer surface of thermal-collecting tube inner bag 2 and are absorbed.
Claims (3)
1, a kind of converging vacuum glass soalr energy heat-collecting pipe comprises thermal-collecting tube inner bag (2), thermal-collecting tube skin (4) and reflecting plate (1), it is characterized in that: installed reflecting plate (1) in the vacuum layer (3) of described glass vacuum heat collection tube of solar energy.
2, glass vacuum heat collection tube of solar energy according to claim 1 is characterized in that: the shape of described reflecting plate (1) is the hyperboloid shape.
