Description

Technical Field

[0001] This invention relates to the field of thermal insulation box technology, and in particular to thermal insulation boxes based on the integrated utilization of solar photovoltaic thermal and semiconductor heating. Background Technology

[0002] As industrialization accelerates, human demand for and consumption of energy are increasing.

[0003] Finding reliable new energy sources requires meeting two conditions simultaneously: first, they must be abundant and inexhaustible; second, they must be safe, clean, and not threaten humanity or damage the environment. Currently, two main types of new energy sources have been identified: solar energy and fuel cells. Solar energy technology is relatively mature and widely used, found in household water heaters, air conditioners, and both residential and industrial power generation.

[0004] Extensive research and design work has been done on photovoltaic (PV) power generation systems. A PV system mainly consists of solar cells, batteries, controllers, and inverters. Solar cells are the core component for light energy conversion. Monocrystalline silicon solar cells have the highest photoelectric conversion efficiency, around 15%, with a maximum of 23%, but their manufacturing cost is high. The lifespan of monocrystalline silicon solar cells is generally 15 years, with a maximum of 25 years. Polycrystalline silicon solar cells have a photoelectric conversion efficiency of 14% to 16%, and their manufacturing cost is lower than that of monocrystalline silicon solar cells, leading to their widespread development. However, the lifespan of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells, resulting in lower overall solar power generation efficiency.

Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0035] The present application provides a thermal insulation box based on the comprehensive utilization of solar photovoltaic photo-thermal and semiconductor heating, as shown in the figure, comprising: Figures 1-5 As shown in the figure, comprising:

[0036] The box body comprises a top plate 17, a hollow cavity 3 and a box door 12, the top plate 17 is arranged at the top of the hollow cavity 3 and one end is suspended, and the box door 12 is arranged on one side wall of the hollow cavity 3;

[0037] The U-shaped heat pipe 2 is clamped on the top plate 17 and comprises a condensation section 16 and an evaporation section 15, the condensation section 16 is arranged at the bottom of the top plate 17, the evaporation section 15 is arranged at the top of the top plate 17, the U-shaped heat pipe 2 is provided with a capillary core 13 and a heat pipe working medium, the evaporation section 15 absorbs the heat energy after the solar energy irradiates to the solar photovoltaic panel 1, so that the heat pipe working medium is vaporized, transported to the condensation section 16 and liquefied to release heat;

[0038] Solar photovoltaic panel 1 is installed at the top of evaporation section 15;

[0039] Battery 8 is connected to solar photovoltaic panel 1 to store the electrical energy converted by solar photovoltaic panel 1;

[0040] A semiconductor heater 4, connected to a storage battery 8, is mounted on a hollow cavity 3 and includes a heating end facing the inside of the housing and a cooling end facing the outside of the housing.

[0041] The temperature distribution assembly includes a temperature distribution plate 5 and heat dissipation fins 6. The temperature distribution plate 5 is connected to the heating end of the semiconductor heater 4, and the heat dissipation fins 6 are disposed on the temperature distribution plate 5.

[0042] This invention utilizes a solar photovoltaic panel 1 to convert solar energy into electrical energy, which is then stored in a battery 8 and used to power a semiconductor heater 4, regulating temperature through semiconductor heating principles. Simultaneously, it utilizes the heat emitted after solar energy irradiates the photovoltaic panel. This heat is absorbed by a U-shaped heat pipe 2 via heat conduction and supplied to the interior of the insulation box. The U-shaped heat pipe 2 contains a capillary wick 13 and a heat pipe working fluid. The evaporation section 15 absorbs the heat energy from the solar photovoltaic panel 1, causing the heat pipe working fluid to vaporize and be transported to the condensation section 16 where it liquefies and releases heat, achieving insulation at higher temperatures. Furthermore, the condensed heat pipe working fluid returns to the evaporation section 15 via capillary action, completing a reciprocating cycle. This invention not only utilizes solar photovoltaic power generation but also leverages the inherent thermal energy of solar energy, resulting in high energy efficiency.

[0043] The present invention comprises a U-shaped heat pipe 2, a solar photovoltaic panel 1, and a semiconductor heater 4 forming a PV / T module. The PV / T module absorbs solar energy to generate photovoltaic power, and at the same time absorbs the heat accumulated behind the photovoltaic panel, thereby improving the efficiency of solar energy utilization and having environmental protection attributes.

[0044] The U-shaped heat pipe 2 placed behind the solar photovoltaic panel 1 of this invention can absorb solar heat and conduct heat for utilization, combining photovoltaic and solar thermal effects to improve the utilization rate of solar energy.

[0045] The U-shaped heat pipe 2 of this invention absorbs heat from the back of the solar photovoltaic panel 1, reducing the overall temperature of the solar photovoltaic panel 1, preventing damage caused by excessive temperature of the solar photovoltaic panel 1 during midday, and improving the service life of the solar photovoltaic panel 1.

[0046] In this invention, such as Figure 1 and Figure 2As shown, one side of the uniform temperature plate 5 is combined with the semiconductor heating end through the heat-conducting silicone grease, and the other side is combined with the heat dissipation fin 6. The heat generated by the semiconductor heater 4 will be evenly diffused to the outside through the uniform temperature plate 5 and the heat dissipation fin 6. Copper is widely used in fin manufacturing due to its low price, large heat conductivity coefficient and strong heat transfer capacity, so the copper strip is used as the heat dissipation fin 6, and the rectangular shape is adopted.

[0047] The heat dissipation fin 6 is used to increase the heat transfer area with air to enhance the heat exchange effect, and can be combined with the base pipe to form a finned tube heat exchanger to increase the radiation heat transfer and the convection heat transfer. In the present application, due to the small space and the use of the fan 7 and the uniform temperature plate 5 to enhance the heat transfer, it is not recommended to use the finned tube heat exchanger, and only the external heat dissipation fin 6 can meet the requirements.

[0048] Among the shapes of the heat dissipation fin 6 widely used at present, the rectangular and triangular shapes have the best heat dissipation effect, and the selection of the two shapes is related to the size of the distance between the heat dissipation fins 6. When the distance is large, the rectangular shape has better heat dissipation effect than the triangular shape, and when the distance is small, the triangular heat dissipation fin 6 is recommended. However, too small distance is not conducive to processing, so the rectangular heat dissipation fin 6 with large distance is adopted. However, if the processing precision of the distance between the heat dissipation fins 6 can be ensured to be about 4mm, the triangular heat dissipation fin 6 can be adopted.

[0049] The uniform temperature plate 5 and the semiconductor are rectangular because the processing on the market is generally rectangular, which is more regular.

[0050] In the present application, in order to make the temperature in the heat preservation box uniform, a plurality of semiconductor heaters 4 are uniformly distributed on the hollow cavity 3, and the semiconductor heaters 4 are bolted to the heat preservation box.

[0051] In the present application, the fan 7 is arranged in the box body to accelerate the heat diffusion and ensure the uniform temperature distribution in the heat preservation box.

[0052] In the present application, one or two heat dissipation fins 6 are arranged on one side wall of the hollow cavity 3, and a plurality of uniform temperature plates 5 are uniformly distributed on the side of the heat dissipation fin 6 close to the side wall of the hollow cavity 3. Each uniform temperature plate 5 is connected with a semiconductor heater 4.

[0053] In the embodiment of the present application, in addition to the first side of the hollow cavity 3 provided with the box door 12, the other side of the hollow cavity 3 is uniformly provided with four uniform temperature plates 5, and the fan 7 is arranged between the four uniform temperature plates 5.

[0054] In the present application, as Figure 5As shown, in order to better absorb solar energy, the heat pipe working fluid is a mixture of carbon tetrachloride and graphene. The tail of the condensation section 16 is formed into a dendritic shape and includes multiple branches 18. The branches 18 are hollow structures, and two connected branches 18 are connected. The outer surface of the branches 18 is provided with multiple uniformly distributed micro fins 19.

[0055] The invention also includes control components, such as Figure 1 As shown, the control component includes a temperature sensor 9, a voltage regulator module 10, and a control panel 11. The control panel 11 is equipped with a display screen, control buttons, and a controller. The temperature sensor 9 is installed inside the hollow cavity 3 to monitor the temperature. The voltage regulator module 10 is electrically connected to the battery 8. The voltage regulator module 10, temperature sensor 9, semiconductor heater 4, display screen, and control buttons are all electrically connected to the controller. The control panel 11 displays the temperature monitored by the temperature sensor 9. The control component, semiconductor heater 4, and fan 7 are all powered by the battery 8.

[0056] To better regulate the temperature inside the insulation box and create a constant temperature environment, the battery 8, after being regulated by the voltage regulator module 10, supplies power to the temperature sensor 9, control panel 11, semiconductor heater 4, and fan 7. The control panel 11 adjusts the required temperature of the insulation box, the U-shaped heat pipe 2 provides a certain amount of heat to the insulation box, and the semiconductor heater 4 further supplements the heat to bring the insulation box to the required temperature. In addition, the invention continuously measures the temperature through the temperature sensor 9, which can continuously adjust the heating power of the semiconductor heater 4. Furthermore, the invention is equipped with a battery 8, which provides energy to the semiconductor heater 4 to maintain the temperature of the insulation box.

[0057] During the summer when temperatures are high and solar irradiance is strong, the semiconductor heater 4 operates less, and the heating power of the semiconductor heater 4 is reduced based on feedback from the control panel 11. Conversely, during the winter when temperatures are low and solar irradiance is low, the heating power of the semiconductor heater 4 is increased based on feedback from the control panel 11. The power is calculated using a built-in algorithm in the controller, taking the temperature of the solar photovoltaic panel 1 backsheet, the internal temperature of the box, and the air flow coefficient inside the box as variables, thus achieving real-time adjustment of the temperature inside the insulation box.

[0058] The cabinet is equipped with EEP insulation material 14 to form an insulated cavity. The hollow cavity 3, the top plate 17 and the door 12 are combined to form an openable constant temperature storage space, forming a sealed space. The door 12 and the hollow cavity 3 are connected by a hinge for opening and closing the door 12.

[0059] In the application, the VC heat-dissipating plate 5 can transfer heat more evenly, and can improve the heat-dissipating efficiency on the heat-dissipating device with small heat-dissipating area, so many video card heat-dissipating devices also use the VC heat-dissipating plate 5 for heat-dissipating design; here, the heat-dissipating area is increased, the heat distribution in the heat-insulating box is evened, and the heat uneven phenomenon of'some parts are hot and some parts are cold' is avoided; secondly, the heat-dissipating effect difference caused by the gravity in the U-shaped heat pipe 2 is prevented; when the U-shaped heat pipe 2 is used, the evaporation and reflux efficiency of some heat-dissipating devices will be affected by the gravity in different heat pipe directions, but when the VC heat-dissipating plate 5 is used, the temperature difference is small.

[0060] In the application, the solar photovoltaic panel 1 and the U-shaped heat pipe 2 are connected through the laminating mode, so that the heat in the heat-insulating box is not easy to leak, and the substances in the heat-insulating box can be in a sealed environment.

[0061] In the application, as shown in the figure, Figure 1 The capillary core 13 is arranged on the inner wall of the U-shaped heat pipe 2, and the heat pipe working medium flows in the capillary core 13.

[0062] In the application, as shown in the figure, Figure 4 In order to increase the heat absorption efficiency, the plurality of U-shaped heat pipes 2 are evenly distributed on the top plate 17.

[0063] As described above, the heat-insulating box provided by the application has two working modes; the working mode one is that the solar photovoltaic panel 1 supplies power to the storage battery 8, the storage battery 8 supplies power to the semiconductor heat generator 4, the temperature is adjusted by the semiconductor heat sheet (when the current passes through the semiconductor heat sheet, heat is generated in the heat-insulating box, the temperature outside the heat-insulating box is lowered, the temperature difference and the heat transfer are generated, the temperature change is fed back through the temperature sensor 9 and the signal is displayed on the control panel 11(11), the automatic control system such as the voltage stabilizing module 10 is used to realize the automatic control of the temperature, the temperature adjustment is flexible, and the application background is wide.

[0064] The working mode two is that the U-shaped heat pipe 2 absorbs the heat energy on the panel of the solar photovoltaic panel 1, the working medium of the U-shaped heat pipe 2 is vaporized, is transported to the condenser pipe, is liquefied and releases heat in the condenser pipe, the condensed working medium moves upward to the evaporation section 15 through the capillary core 13, and the reciprocating circulation of the working medium is realized. The U-shaped heat pipe 2 reduces the heat dissipation in the heat-insulating box through the heat-insulating material 14.

[0065] The heat-insulating box based on the solar photovoltaic light-heat and semiconductor heat comprehensive utilization provided by the application can have the above two working modes, can use the heat energy of the solar energy itself, realizes the coupling heat generation, and has high practicability.

[0066] Specifically, when the semiconductor heater 4 is not working (i.e., working mode two), the controller in the control panel 11 is turned on. The temperature sensor 9 monitors the temperature information of the inside side of the box and sends it to the controller. The controller compares the temperature inside the insulation box with a preset threshold. When the temperature inside the insulation box is lower than the preset threshold, the controller determines that the heat inside the box is insufficient. The controller connects the battery 8 and the semiconductor heater 4 to supply power to the semiconductor heater 4, making the semiconductor heater 4 work, and simultaneously turning on working mode one. When the temperature inside the box is higher than the threshold, the controller determines that the heat inside the box is sufficient. The battery 8 and the heating system remain disconnected, and only the heat energy on the solar photovoltaic panel 1 is absorbed through the U-shaped heat pipe 2 (i.e., working mode two).

[0067] In addition, the control buttons include a battery 8 switch and a semiconductor heater 4 switch, which control the connection and disconnection between the battery 8 and the semiconductor heater 4 by turning the battery 8 switch or the semiconductor heater 4 on or off.

[0068] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
