Embodiment Construction
[0031] Such as Figure 1-2 As shown, the reflector of the reflective heat collector involved in the present invention is composed of a main reflector 2 and a secondary reflector 3 . The reflective surface 1 of the main reflector is a parabolic cylindrical mirror, that is, any cross-section thereof is a parabola 5 with the same shape, the focus of which is 6, and the apex is 7. Connecting the vertices or focal points of the parabolas formed by each cross section is the top line AA' or focal line BB' of the reflecting surface of the main reflector. The plane formed by the top line and the focal line is a symmetrical longitudinal section of the reflecting surface of the main reflector. When the reflective surface of the main reflector is placed facing the sun, the reflective surface can converge and reflect the light irradiated on it to its focal line. The reflective surface 4 of the secondary reflector is a plane reflector. The secondary reflector can reflect the light irra...

The utility model relates to a solar water heater using a plurality of reflective heat collectors, which is composed of a plurality of reflective heat collectors and a water circulation device. The reflective heat collector is composed of reflector, heat collecting tube, sun tracking device and bracket. Multiple reflective collectors used in solar water heaters are arranged in several rows or columns in a matrix, and can be rotated horizontally or vertically under the drive of a common motor responsible for horizontal or vertical rotation. Its characteristics are: the reflective heat collector has the advantages of fast heating and high equilibrium temperature; the use of secondary reflectors effectively reduces the cost of the reflective heat collector; this solar water heater using multiple reflective heat collectors is Efficient and large-scale utilization of solar energy provides an effective method.
Description
technical field [0001] The invention relates to a device for heating water by using solar energy, in particular to a solar water heater using multiple reflective heat collectors. Background technique [0002] Due to the continuous increase in the demand for energy in human production and life, the price of energy has risen rapidly. At the same time, the problem of environmental pollution caused by the extensive use of fossil energy such as coal and petroleum is becoming more and more serious. Energy saving and environmental protection are more and more problems that are mentioned and urgently needed to be solved in the current energy use and production process. [0003] Solar energy is a kind of energy with huge reserves and no pollution. But we still haven't solved the problem of how to use solar energy efficiently and on a large scale. Taking the more common direct sunlight solar water heater as an example, although the vacuum layer between the inner and outer tank...
