The effect of the light condensing assembly in the application is to converge solar energy to the vicinity of a light condensing point, so that as much solar energy as possible can be irradiated on a solar cell and collected and utilized by a solar cell panel, the light condensing assembly can be a lens capable of converging light rays, and technicians in the field such as specific lens materials and specifications can select the light condensing assembly in the prior art.
Since the earth and the sun continuously move relatively to each other, so that the incident direction of the sun is changed at any moment, the solar tracking assembly is arranged to enable the light to vertically irradiate the light-gathering assembly as much as possible.
The solar cell can directly convert light energy into electric energy through a photoelectric effect or a photochemical effect, and the converted electric energy is stored in the storage battery and used by electric equipment.
Since the solar cell cannot convert all light energy into electric energy, a part of the light energy is converted into heat energy, and the purpose of the heat energy collecting module is to collect the part of the heat energy as much as possible. The heat energy collecting device in the embodiment comprises a heat collecting pipe 1 and a heat collecting tank 2, wherein heat exchange liquid is filled in the heat collecting tank 2, and the heat exchange liquid leaves from the heat collecting tank 2, enters the heat collecting pipe 1, absorbs heat in the heat collecting pipe 1 and then returns to the heat collecting tank 2. In addition, in order to enable the collected heat to be utilized, a first heat exchange box 3, a heat conduction pipe 5, a second heat exchange box 4 and a heat exchange device 6 which are connected in sequence are further arranged, low-temperature liquid leaves from the first heat exchange box 3 and enters the heat conduction pipe 5, the heat conduction pipe 5 absorbs the heat in the heat collection box 2 and then enters the second heat exchange box 4, then the low-temperature liquid leaves from the second heat exchange box 4 and transfers the heat to the heat exchange device 6 through the heat exchange device 6, and then the low-temperature liquid returns to the first heat exchange box 3 again, so that the heat transfer and utilization are realized.
For the same region, the irradiation intensity of the sunlight at the same time in different seasons or at different times on the same day is greatly different, so the embodiment further comprises a thermal management module. The heat energy collection module in this embodiment can be provided with one or more according to the circumstances, and the heat energy management module can adjust the opening or the opening degree of heat energy collection module according to actual conditions, specifically: the thermal management module monitors the flow rate of the liquid in the heat collecting tube 1 and the heat conducting tube 5 and the temperature of the liquid in the first heat exchange box 3 and the second heat exchange box 4. For example, when the temperature of the liquid outlet of the heat collecting tank 2 is too high, it indicates that the heat exchange is insufficient, and the flow rate of the liquid in the heat conducting pipe 5 can be increased according to the requirement, or the number of the heat exchange pipes can be increased, so as to increase the heat exchange area; if the conditions allow, the flow velocity of the liquid in the heat collecting pipe 1 can be reduced, the heat exchange time is prolonged, and vice versa.
The thermal management module can monitor data, compares the monitored data with preset parameters, and determines whether the specified switch is turned on or turned off.
Further, the light condensing assembly is a Fresnel lens.
Fresnel lenses are capable of converting light from a relatively large area to a relatively small area, allowing for light collection, and can be sized larger than glass while being lighter and more economical.
Furthermore, the solar cell is a triple junction gallium arsenide solar cell.
GaAs belongs to III-V group compound semiconductor materials, the energy gap of the GaAs is matched with the solar spectrum more suitably, and the GaAs can resist high temperature. Compared with a silicon solar cell, the GaAs solar cell has better performance.
Furthermore, more than two heat collecting boxes 2 are sequentially arranged between the heat exchange liquid inlet and the heat exchange liquid outlet of the heat collecting tube 1, and each heat collecting box 2 is correspondingly provided with a first heat exchange box 3 and a second heat exchange box 4.
More than two heat collecting tanks 2 are arranged in sequence, and the graded utilization of heat can be realized according to the specific conditions of the heat exchange equipment 6 or the heat utilization equipment. The embodiment can collect heat energy by using the boiling point difference of liquid in the multistage heat conduction pipes, for example: the material is used in a heat conduction pipe at a low temperature (-70-200 ℃): freon, ammonia, acetone, methanol, ethanol, heptane, water, or the like; the medium temperature (200-500 ℃) end heat conduction pipe is used as follows: naphthalene, dowtherm, thermex, sulfur or mercury, etc.; the high-temperature (500-1000 ℃) end heat conduction pipe is used as follows: cesium, rubidium, potassium or sodium, etc.; the high-temperature extremely-high-temperature (> 1000 ℃) end heat conduction pipe is used: lithium, calcium, lead, indium or silver, etc. When the device is specifically arranged, the heat exchange liquid in the heat collection pipe 1 can sequentially pass through the high-temperature end, the medium-temperature end and the low-temperature end. In some areas or some times, when the light intensity is weak and the high temperature end, or even the middle temperature end cannot be reached, the corresponding heat conduction pipe 5 can be closed.
According to the actual working conditions, a person skilled in the art can use the same liquid as that in the heat conduction pipe 5 at the high temperature end, the high temperature end and the medium temperature end without grading the heat quantity.
Further, a connecting pipe 7 is arranged between the liquid inlet and the liquid outlet of each heat collecting tank 2.
When the heat collection tank 2 needs to be started, the valve on the connecting pipe 7 may be closed, so that the heat exchange fluid passes through the heat collection tank 2; when the heat collection box 2 does not need to be started, the valve on the connecting pipe 7 can be opened, and the valve at the inlet and the outlet of the heat collection box 2 is closed, so that the heat exchange liquid passes through the connecting pipe 7 and does not pass through the heat collection box 2, and the heat management module can conveniently manage the heat mobile phone device.
In summer or at midnoon, the illumination intensity is high, more heat is collected by the heat collecting pipes 1, more heat collecting tanks 2 may need to be started, and less heat is collected by the heat collecting pipes 1 at night or in winter, and fewer heat collecting tanks 2 may need to be started.
Furthermore, more than two heat collecting boxes 2 are connected in parallel between a heat exchange liquid inlet and a heat exchange liquid outlet of the heat collecting tube 1, and each heat collecting box 2 is correspondingly provided with a first heat exchange box 3 and a second heat exchange box 4.
More than two heat collecting tanks 2 are arranged in parallel, when the illumination intensity is high, more heat collecting tanks 2 can be opened, when the illumination intensity is low or even no illumination intensity is available, all heat collecting tanks 2 can be reduced or closed, the control is convenient, and each heat exchange device 6 obtains similar heat energy.
Further, the heat conduction pipe is a flat pipe, and the contact area is increased.
Further, the first heat exchange box 3 is positioned below the corresponding second heat exchange box 4, so that the heat exchange efficiency is improved.
Furthermore, the solar energy heat collecting tube further comprises an energy recovery device which comprises a temperature difference sheet, wherein the temperature difference sheet is positioned between the heat collecting tube 1 and the solar cell, and the temperature difference sheet is connected with a power utilization or storage device.
