Description

Technical Field

[0001] The utility model belongs to the technical field of solar power generation, and in particular relates to a solar power generation device. Background Art

[0002] The existing solar power generation device generally only has a solar panel to convert light energy into electrical energy. However, the unconverted light energy in the solar panel is converted back into heat energy. If the temperature of the solar panel is too high, on the one hand, it will cause the performance of solar energy to decline, which is not conducive to the power generation of the solar panel; on the other hand, the heat energy cannot be used, resulting in waste. In addition, the temperature of the current solar panel cannot be controlled. Too low or too high a temperature is not conducive to solar power generation. Utility Model Content

[0003] The utility model provides a solar power generation device, aiming to solve the problems in the prior art that the temperature of the solar cell panel in the solar power generation device is uncontrollable and the thermal energy utilization rate is low.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a solar power generation device, which is provided with a solar cell panel, a heat conduction plate, a thermoelectric power generation sheet, a phase change generating chamber and a rear cover plate in sequence from front to back; the thermoelectric power generation sheet is provided with a positive electrode and a negative electrode for supplying power to the outside; the solar panel is provided with a positive electrode and a negative electrode for supplying power to the outside; the heat conduction plate is arranged on the back of the solar panel and is used to transfer the heat energy on the solar cell panel to the thermoelectric power generation panel for generating electricity, and the phase change generating chamber is used to store the residual heat energy of the thermoelectric power generation sheet that is not converted into electrical energy.

[0005] A further improved solution: the phase change temperature in the phase change chamber is within the range of 25-35°C.

[0006] Based on the above scheme, the temperature of the solar panel can be controlled at about 25-35°C through the phase change chamber, at which the solar panel has the best power generation effect.

[0007] A further improved solution: a shell is provided on the solar panel, the solar panel is arranged on the front surface of the shell, and a cavity for accommodating a heat conducting plate, a temperature difference power generation sheet and a phase change generating chamber is formed between the shell and the rear cover.

[0008] Further improved solution: the solar cell panel and the heat conducting plate are connected with thermally conductive adhesive, the heat conducting plate and the temperature difference power generation sheet are connected with thermally conductive adhesive, and the temperature difference power generation sheet and the phase change generating chamber are connected with thermally conductive adhesive.

[0009] Based on the above scheme, two adjacent components are connected by thermally conductive adhesive, which can avoid the generation of gaps when the two adjacent components are directly connected. Since the existence of gaps will reduce the thermal conductivity efficiency, the above scheme can improve the thermal conductivity efficiency by filling thermally conductive adhesive.

[0010] Further improved solution: a cooling module is provided between the phase change chamber and the rear cover plate.

[0011] Based on the above solution, heat can be recycled by setting a cooling module.

[0012] A further improved solution: the cooling module comprises a heat conducting plate and a medium flow pipe arranged on the heat conducting plate.

[0013] Based on the above solution, heat can be recovered and utilized through the medium flow pipe.

[0014] A further improved solution: the phase change temperature in the phase change chamber is within 40-45°C.

[0015] Based on the above scheme, 40-45°C is suitable for human body temperature. Therefore, by setting the phase change temperature in the phase change chamber within 40-45°C, a living temperature can be provided.

[0016] A further improved solution: the heat-conducting substrate and the phase change chamber are connected with each other by using heat-conducting glue.

[0017] Based on the above scheme, the thermally conductive substrate and the phase change chamber are connected by thermally conductive glue, which can avoid the generation of gaps when the adjacent thermally conductive substrates and phase change chambers are directly connected. Since the existence of gaps will reduce the thermal conductivity efficiency, the thermally conductive substrate and the phase change chamber can improve the thermal conductivity efficiency by filling with thermally conductive glue.

[0018] A further improved solution: the medium in the medium flow pipe is water.

[0019] Based on the above scheme, water can be used to provide daily water at a suitable temperature for bathing, etc.

[0020] A further improved solution: a heat preservation plate is provided between the phase change chamber and the rear cover plate.

[0021] Based on the above solution, the use of insulation boards can reduce heat loss and allow the heat to be absorbed and reused.

[0022] The beneficial effects of the utility model are:

[0023] The solar cell power generation device in the utility model is provided with a phase change chamber, which can be used to store the heat energy converted from solar energy and maintain it at a specific temperature for a long time, so as to control the temperature of the solar cell panel, avoid the temperature being too high or too low, and make the solar cell panel maintain a better power generation performance; in addition, the utility model is also provided with a temperature difference power generation sheet, which can convert the heat energy converted from solar energy into electrical energy again, so as to improve the power generation effect; in addition, at night, after the temperature of the temperature difference power generation sheet close to the solar cell panel is reduced, the temperature in the phase change chamber is maintained at a higher temperature, forming a reverse temperature difference, so that the heat energy in the phase change chamber can be converted into electrical energy, and all-weather power generation can be achieved by releasing heat energy.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0031] Embodiment 1:

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a solar power generation device, which is provided with a solar cell panel 1, a heat conductive plate 2, a thermoelectric power generation sheet 3, a phase change generating chamber 4 and a rear cover plate 8 in sequence from front to back; the thermoelectric power generation sheet 3 is provided with a positive electrode and a negative electrode for supplying power to the outside; the solar cell panel 1 is provided with a positive electrode and a negative electrode for supplying power to the outside; the heat conductive plate 2 is arranged on the back of the solar cell panel 1 and is used to transfer the heat energy on the solar cell panel 1 to the thermoelectric power generation panel for generating electricity, and the phase change generating chamber 4 is used to store the residual heat energy of the thermoelectric power generation sheet 3 that is not converted into electrical energy.

[0033] Among them, the phase change temperature in the phase change chamber 4 is within 25-45°C; the specific temperature setting can be set according to actual needs. The phase change materials filled in the phase change chamber 4 are different, and the phase change temperature is also different. The phase change material can be purchased directly on the market according to the demand for phase change temperature. For example: the microcapsule phase change material with model TH-ME25 has a phase change temperature of 25°C; the microcapsule phase change material with model TH-ME28 has a phase change temperature of 28°C.

[0034] On the basis of the above solution, more specifically, a shell 10 is provided on the solar panel 1, and the solar panel 1 is arranged on the front surface of the shell 10, and a cavity for accommodating the heat conducting plate 2, the temperature difference power generation sheet 3 and the phase change generating chamber 4 is formed between the shell 10 and the rear cover plate 8. The shell 10 is preferably square, and the cavity is arranged on the back of the shell 10.

[0035] See also Figure 1 In order to connect adjacent components together and form a better heat conduction effect, based on any of the above schemes, the solar cell panel 1 and the heat conducting plate 2 are connected by thermal conductive glue 9, the heat conducting plate 2 and the temperature difference power generation sheet 3 are connected by thermal conductive glue 9, and the temperature difference power generation sheet 3 and the phase change generating chamber 4 are connected by thermal conductive glue 9.

[0036] The present embodiment is further described below in conjunction with the working principle:

[0037] In this embodiment, after sunlight irradiates the solar cell panel 1, part of the light energy is converted into electrical energy, which is then supplied to the outside through the positive and negative electrodes; part of the light energy is converted into thermal energy, which is then transferred to the temperature difference power generation sheet 3 after passing through the heat conductive plate 2. The temperature difference power generation sheet 3 converts part of the thermal energy into electrical energy, which is then supplied to the outside through another set of positive and negative electrodes, and part of the thermal energy is transferred to the phase change generating chamber 4 for storage, and the temperature of the solar cell panel 1 is adjusted.

[0038] At night, after the temperature of the side of the temperature difference power generation sheet close to the solar panel drops, the temperature in the phase change chamber is kept at a higher temperature, forming a reverse temperature difference, so that the heat energy in the phase change chamber can be released and converted into electrical energy using the temperature difference power generation sheet.

[0039] Embodiment 2:

[0040] See also Figure 3 On the basis of the first embodiment, a cooling module for absorbing and utilizing the heat energy in the phase change chamber 4 is further provided between the phase change chamber 4 and the rear cover plate 8 .

[0041] Specifically, the cooling module includes a heat-conducting substrate 5 and a medium flow pipe 6 arranged on the heat-conducting substrate 5; heat can be recycled through the medium flow pipe 6.

[0042] In order to provide a living temperature, the phase change temperature in the phase change chamber 4 is preferably within a range of 40-45°C.

[0043] The heat-conducting substrate 5 and the phase change chamber 4 are connected by heat-conducting adhesive 9. The heat-conducting substrate 5 and the phase change chamber 4 are connected by heat-conducting adhesive 9, which can avoid the generation of gaps when the adjacent heat-conducting substrates 5 and the phase change chamber 4 are directly connected. Since the existence of the gap will reduce the heat conduction efficiency, the heat-conducting substrate 5 and the phase change chamber 4 can improve the heat conduction efficiency by filling the heat-conducting adhesive 9.

[0044] In order to provide domestic water with a suitable temperature for bathing, etc., the medium in the medium flow pipe 6 is water.

[0046] The utility model is further described below in conjunction with the working principle:

[0047] The heat stored in the phase change generating chamber 4 can be transferred to the medium flow pipe 6 through the heat conductive substrate 5. After the water in the medium flow pipe 6 absorbs the heat, it is used as domestic water.

[0048] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
