Description
本实用新型涉及镜反射复合抛物聚光器，根据边缘光线原理，可将给定接收角范围内的入射光线按设想的聚光比收集在接收器上。实验郊果是比现热管真空管(板状集热板)吸热快，吸热效率高出1.5倍，可较大程度地降低成本，可用于较高温度的特殊用途。因此，利于开辟新的生活和工业用热市场，故应用范围很广。The utility model relates to a mirror-reflection compound parabolic concentrator, which can collect incident light within a given receiving angle range on a receiver according to a conceived concentrating ratio according to the principle of edge rays. The result of the experiment is that it absorbs heat faster than the existing heat pipe vacuum tube (plate-shaped heat collector), and the heat absorption efficiency is 1.5 times higher, which can greatly reduce the cost and can be used for special purposes with higher temperatures. Therefore, it is beneficial to open up new domestic and industrial heat markets, so it has a wide range of applications.
目前太阳能热水器，除全玻璃真空管外，就是热管真空管。全玻璃真空管价格低廉，但易冻，管内易结水垢，加之生产简单，遍地生产，市场已有饱和之势。热管真空管具有耐冷冻，启动快，保温好等优点，深受用户欢迎，但价位较高，因此，安装者数量有限。如何利用两者的优点，尤其是提高热管真空管集热器工作温度，增加效率，降低成本，是开辟新领域扩大太阳能用热市场立足的关键所在。太阳能镜反射复合抛物聚光器就是为此而设计的。At present, solar water heaters, except all glass vacuum tubes, are heat pipe vacuum tubes. The all-glass vacuum tube is cheap, but it is easy to freeze, and scale is easy to form inside the tube. In addition, the production is simple and it is produced everywhere. The market is already saturated. The heat pipe vacuum tube has the advantages of freezing resistance, fast start-up, good heat preservation, etc., and is very popular among users, but the price is relatively high, so the number of installers is limited. How to make use of the advantages of both, especially to increase the working temperature of heat pipe vacuum tube collectors, increase efficiency and reduce costs, is the key to opening up new fields and expanding the solar heat market. Solar mirror reflective compound parabolic concentrators are designed for this purpose.
本实用新型的技术方案如下：在玻璃真空管(1)内置入由镜反射复合抛物聚光面(2)和接收体(3)组成的太阳能镜反射复合抛物聚光器，加上玻璃真空管(1)就组成了太阳能镜反射复合抛物内聚光热管真空管集热器和以热管真空管为接收器(3)，只在外部增设一套镜反射复合抛物聚光面(2)就组成了太阳能镜反射复合抛物外聚光热管真空管集热器。同样若以全玻璃真空管为接收器(3)在外部增设一套镜反射复合抛物聚光面(2)就组成了太阳能镜反射复合抛物外聚光全玻璃真空管集热器。镜反射复合抛物聚光面的材料可用镀锌铝板简单加工而成，将其应用在太阳能集热器中将减少集热管，收到很好的效果。The technical scheme of the utility model is as follows: a solar mirror reflective compound parabolic concentrator composed of a mirror reflective compound parabolic concentrating surface (2) and a receiver (3) is embedded in the glass vacuum tube (1), and the glass vacuum tube (1 ) has just formed the solar mirror reflection compound parabolic inner concentrating heat pipe vacuum tube collector and the heat pipe vacuum tube as the receiver (3), only adding a set of mirror reflection compound parabolic concentrating surface (2) has just formed the solar mirror reflection Compound parabolic external concentrating heat pipe vacuum tube collector. Equally if take all-glass vacuum tube as receiver (3), set up a set of mirror reflective compound parabolic concentrating surface (2) on the outside and have just formed solar mirror reflective compound parabolic external concentrating all-glass vacuum tube heat collector. The material of the specular reflective compound parabolic concentrating surface can be simply processed by galvanized aluminum plate, and its application in the solar heat collector will reduce the number of heat collecting tubes and receive good results.
镜反射复合抛物面由二条母线为方程的抛物球面相交而成。图4两条对称轴NA.NB夹角为45°，复合抛物面由有共同焦点F的两条抛物线M1A、M2B和M1O1M2一段园的渐开线共同组成。两条抛物线的主轴M1B、M2A间夹角为2a即接收角。由反射聚焦的原理可知，抛物线能把与其主轴平行的光线会聚成一点，抛物柱面能把与其主轴平行的光线会聚成一条直线(焦线)。早上当太阳能从东方升到某高度时，入射光线和M2A平行，这时到抛物线M2B上的光线反射后聚焦在F点。当太阳能继续移动，则光线就由M2A逐渐向M1B方向运动。在此过程中阳光在抛物线M2B上的入射角逐渐增大，反射角也由小变大，于是反射后的光斑就沿FM2逐渐向M2下移；而对于抛物线M1A而言，情况正好相反，阳光在抛物线M1A上的入射角逐渐变小，反射角也逐渐由大变小，反射后的光斑沿M1F向M1向F方移动，当入射光线和M1B平行时，反射后会聚在F点。由此可见反射光始终是射在FM1和FM2之间，将接收体放在此处，就能有效地提高吸收光线的能量密度。The mirror reflection compound paraboloid is formed by the intersection of two paraboloids whose generatrices are equations. The angle between the two symmetry axes NA and NB in Fig. 4 is 45°, and the compound paraboloid is composed of two parabolas M 1 A, M 2 B and M 1 O 1 M 2 with a common focus F and an involute of a circle. The included angle between the main axes M 1 B and M 2 A of the two parabolas is 2a, which is the acceptance angle. According to the principle of reflective focusing, a parabola can converge the rays parallel to its principal axis into a point, and a parabolic cylinder can converge the rays parallel to its principal axis into a straight line (focal line). In the morning, when the solar energy rises to a certain height from the east, the incident light is parallel to M 2 A, and at this time, the light on the parabola M 2 B is reflected and focused at point F. When the solar energy continues to move, the light will gradually move from M 2 A to M 1 B. During this process, the incident angle of sunlight on the parabola M 2 B gradually increases, and the reflection angle also changes from small to large, so the reflected light spot gradually moves down to M 2 along FM 2 ; while for the parabola M 1 A , the situation is just the opposite. The incident angle of sunlight on the parabola M 1 A gradually decreases, and the reflection angle gradually decreases from large to small. The reflected light spot moves from M 1 F to M 1 to F. When the incident light and M 1 B When they are parallel, they converge at point F after reflection. It can be seen that the reflected light is always shot between FM 1 and FM 2 , and placing the receiver here can effectively increase the energy density of the absorbed light.
本实用新型与现有全玻璃真空管和热管真空管相匹配就构成了新的镜反射复合抛物(内外)聚光型全玻璃真空管热水器和镜反射复合抛物聚光型(内外)热管式真空管热水器，由于本实用新型热得快，温度高，(达到95℃以上)这就给用于开水器和太阳能，干燥器，太阳炉，热力发电等领域开发提供了重要条件。The utility model is matched with the existing all-glass vacuum tube and the heat pipe vacuum tube to form a new mirror reflection composite parabolic (inside and outside) concentrating all-glass vacuum tube water heater and a mirror reflection composite parabola concentrating type (inside and outside) heat pipe vacuum tube water heater. The utility model heats up quickly, and the temperature is high (reaching more than 95° C.), which provides important conditions for the development of fields such as water boilers, solar energy, dryers, solar furnaces, and thermal power generation.
