Abstract
The utility model provides a novel light-focusing glass vacuum solar heat collecting pipe, which comprises an inner chamber of the glass vacuum heat collecting pipe, an outer layer and a reflecting plate. The utility model is characterized in that compared with the existing glass vacuum solar heat collecting pipe, the space of a vacuum layer is increased; the hyperboloid reflecting plate is arranged in the vacuum layer. The novel light-focusing glass vacuum solar heat collecting pipe has the multiple advantages of high heat collecting efficiency, low cost, etc.
Description
The utility model provides a kind of novel converging vacuum glass soalr energy heat-collecting pipe.
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.Spacing between the thermal-collecting tube is about as much as the outer field caliber of 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) quite a few sunshine can not be utilized owing to reflex to environment space.(2) since reflecting plate below thermal-collecting tube, easy dust stratification easy cleaning and cause reflection efficiency low not again, thus influence the thermal efficiency of thermal-collecting tube.
The technical solution of the utility model is: (1) glass heat-collecting vacuum tube inner bag and outer field caliber are than about about 1: 3, and the caliber of inner bag is similar with the inner bag caliber that has traditional glass heat-collecting vacuum tube now, but have strengthened the outer caliber of thermal-collecting tube.(2) the light collecting reflecting plate of the hyperboloid of particular design is placed in the vacuum layer of thermal-collecting tube.The sunlight of different angles directive hyperboloid 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 solar water heater that converging vacuum glass soalr energy heat-collecting pipe of the present utility model is formed is closely to arrange in a row, and the minute surface of hyperboloid 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 utility model solar energy heat collection pipe embodiment 1;
Fig. 3 is the vertical view of the A-A section of the utility model solar energy heat collection pipe embodiment 1;
Fig. 4 is the front view of the utility model solar energy heat collection pipe embodiment 2.
Embodiment 1:
As Fig. 1, Fig. 2, the utility model converging vacuum glass soalr energy heat-collecting pipe first embodiment shown in Figure 3, comprise thermal-collecting tube mouth of pipe skin 1, thermal-collecting tube inner bag 2, vacuum layer 3, thermal-collecting tube skin 4, hyperboloid reflecting plate 5 and hyperboloid intersecting straight lines 6.
The thermal-collecting tube mouth of pipe outer 1 is whole transparent glass layers that link to each other with 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 5 is made minute surface, and the width of hyperboloid reflecting plate 5 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 5.Light is penetrated outer surface at thermal-collecting tube inner bag 2 through the reflection of hyperboloid reflecting plate 5 minute surfaces or refraction back homopolymerization, absorbs and transfers heat energy to thereby be painted on coating for selective absorption on the outer surface of thermal-collecting tube inner bag 2.Heat energy is passed to water or other media in the inner bag by the tube wall of thermal-collecting tube inner bag 2 again.
Embodiment 2:
The utility model second embodiment as shown in Figure 4, its basic structure is identical with first embodiment, its difference is that the converging vacuum glass soalr energy heat-collecting pipe of embodiment 1 is unidirectional opening, and the converging vacuum glass soalr energy heat-collecting pipe of embodiment 2 is two-way opening, also can be described as the through type glass vacuum heat collection tube of solar energy.Its function is to be convenient to insert in thermal-collecting tube inner bag 2 metal sleeve, and the solar heat energy that the wall of thermal-collecting tube inner bag 2 obtains is passed to the metal sleeve wall and reached the interior water of metal sleeve again.Second embodiment of the present utility model is particularly useful for the solar energy central collecting system.
Claims (3)
1, a kind of converging vacuum glass soalr energy heat-collecting pipe, comprise thermal-collecting tube inner bag (2), thermal-collecting tube skin (4) and hyperboloid reflecting plate (5), it is characterized in that: in the vacuum layer (3) of described glass vacuum heat collection tube of solar energy, installed hyperboloid reflecting plate (5).
2, solar energy heat collection pipe according to claim 1 is characterized in that: described solar energy heat collection pipe is unidirectional opening.
