Description

Sunlight focusing water heater

The technical field is as follows:

the sunlight focusing water heater belongs to the technical field of solar energy utilization.

Background art:

like the magnifier and the multi-lens assembly, the crystal ball also has the sunlight focusing function. Different from the above, any point on the lighting spherical surface of the crystal ball is the optimal lighting point, the sun does not need to be tracked, and any point under the ball is the optimal focusing point without adjusting the focusing height. Relative to the orbit of the earth, moving with the sun, and crystalsThe focus point under the sphere corresponding to the spherical lighting surface also moves automatically, and the whole focusing process is not interrupted due to the change of the position of the sun. The heat energy obtained by sunlight focusing of the crystal ball in a certain period of time of the water heater can be calculated according to the following formula: h ═ J/m²X EA x Cl x N-HL, wherein H represents the heat energy generated by the focusing of sunlight, J/m²For a certain period of time of solar radiation measurement, EA is the area of a crystal sphere exposed to direct solar radiation, Cl is the sunlight focusing coefficient of the crystal sphere, and if the focusing coefficient of a crystal sphere with the diameter of 100 mm is 1, the focusing coefficients of crystal spheres with the diameters of 300 mm, 200 mm, 80 mm or 50 mm are respectively 3, 2, 0.8 and 0.5, and so on, N is the number of crystal spheres, and HL is heat loss. In a relatively adiabatic environment, heat collection and conduction are key factors for fully utilizing sunlight to focus heat energy. The heating efficiency of a water heater depends on the total heat captured, the efficiency of heat collection and conduction, the effectiveness of the insulation, and the temperature of the water when initially injected into the storage. The water heater adopts 16 crystal balls with the diameter of 80 millimeters as a heat source of the water heater. The basic working principle of the water heater is that heat energy generated by the crystal ball through sunlight focusing is absorbed by the heat-collecting bowl mouth and is directly transmitted to the heated tube; in the gradual heating process, due to the temperature difference effect of water, the water in the heated pipe and the water storage pipe forms convection, so that the water with different temperatures is mixed. The heating process of the water heater does not generate carbon emission. Carbon emissions generated during the production process of crystal balls, metals, rubbers, etc. parts can be neutralized by long-term use.

The positions of the lock ring and the lock rod are required to be correspondingly consistent. (4) The assembled heated tube, water storage tube, and heat collecting/conducting rod were placed in a foam insulated cabinet (fig. 16). In the foam heat insulation box, one end of a hot water resistant hose is screwed on a water inlet interface welded on a water storage pipe through a nut, and the other end of the hose is screwed on a nonmetal water outlet interface of a metal shell through a nut. And the other hose is screwed on the water outlet port welded on the water storage pipe through a nut, and the other end of the hose is screwed on the non-metal water outlet port of the metal shell through a nut. The nylon rope is threaded into the handle hole. The cover of the foam heat insulation box is adhered to the four sides of the foam heat insulation box by silica gel.

(6) And (3) adhering the heat-insulating sealing rubber gasket for fixing the crystal ball to the inner side of the metal shell cover, wherein the circular holes of the shell cover and the rubber gasket are required to be correspondingly consistent. The gaps around the 16 heat collecting/conducting rods were sealed with silicone on top of the foam insulated box cover. The insulating enclosure cover is snapped over the top of the insulating enclosure and the snap-lock is snapped in place. The overall length of the assembled water heater was 958 mm, the overall width was 758 mm, and the overall height was 335 mm. The assembly effect of the water heater is shown in fig. 20.

The water heater is suitable for wide middle and low latitude areas (30 degrees N-30 degrees S), including most parts of east Asia, southeast Asia, middle east, Africa, North America and south America, but is not suitable for high latitude areas and polar regions. The crystal ball array of the water heater is kept parallel to the moving track of the sun as much as possible so as to obtain the longest time of solar irradiation. The water heater operates in clear sky and without trees, buildings and terrain shelters, but cannot normally work in cloudy days and at night.
