Utility Model Content

[0005] In order to dissipate heat from a solar power conversion circuit, the present application provides a power supply device with a solar power conversion circuit.

[0006] The present application provides a power supply device with a solar power conversion circuit that adopts the following technical solutions:

[0007] A power supply device with a solar power conversion circuit includes a fuselage, a photovoltaic panel connected to the outside of the fuselage, and a power conversion module fixedly arranged in the fuselage. A cooling water pipe is fixedly connected in the fuselage, with both ends of the cooling water pipe extending from both ends of the fuselage respectively. One end of the cooling water pipe is fixedly connected to a water inlet pipe, and the other end of the cooling water pipe is fixedly connected to a water outlet pipe. The outlet pipe is fixedly connected to an evaporation box, which is arranged at the bottom of the photovoltaic panel. A heat conducting plate is fixedly connected to the top of the evaporation box, and the heat conducting plate abuts against the bottom of the photovoltaic panel. The evaporation box is fixedly connected to a steam pipe, which is fixedly connected to a solenoid valve and a compressor. The other end of the steam pipe is fixedly connected to a turbine, and the turbine is fixedly connected to a transmission rod, which drives the transmission rod to rotate.

[0008] The fuselage is provided with a cooling fan, the transmission rod is fixedly connected to the cooling fan, the turbine is fixedly connected to a return water pipe, the other end of the return water pipe is fixedly connected to a cooling water tank, the cooling water pipe is fixedly connected to the cooling water tank, and the cooling water pipe is fixedly connected to a water pump.

[0009] By adopting the above solution, the cooling water pipes allow water to flow through the interior of the fuselage, and the cooling fan cooperates with the cooling of the interior to cool and dissipate heat. After absorbing heat, the water flows into the evaporator. Due to the extremely high temperature on the back of the photovoltaic panel, the evaporator absorbs the temperature on the back of the photovoltaic panel through the heat conduction plate, accelerating the evaporation of the water in the evaporator. The evaporated water vapor enters the compressor through the steam pipe. The user can control the amount of steam entering the compressor by controlling the solenoid valve to avoid insufficient steam causing the turbine to malfunction. After compressing a certain amount of steam, the compressor guides the steam into the turbine, which drives the cooling fan. The condensed water then flows back to the cooling water tank through the return water pipe to cool down. It is then pumped into the cooling water pipe by the water pump for circulation. The higher the ambient temperature, the more frequently the cooling fan is activated, and the better the cooling effect. At the same time, the heat conduction plate can also reduce the temperature of the photovoltaic panel, providing a certain cooling protection effect for the photovoltaic panel.

[0010] Preferably, the power supply conversion module includes an inverter electrically connected to the photovoltaic panel, a voltage regulator electrically connected to the inverter, and an AC / DC transformer electrically connected to the voltage regulator.

[0011] By adopting the above solution, the DC power generated by the photovoltaic panel is converted into AC power through the inverter, stabilized at the voltage stabilizer, and finally converted into high-voltage and stable DC power for transmission through the AC / DC transformer.

[0012] Preferably, the turbine includes a shell fixedly connected to the steam pipe, a rotor rotatably connected inside the shell, turbine blades fixedly connected to the rotor, a transmission rod fixedly connected to the rotor, and a cooling water pipe fixedly connected to one end of the shell away from the steam pipe.

[0013] By adopting the above solution, steam is introduced into the outer shell through the steam pipe, driving the turbine blades to rotate, and the rotor drives the transmission rod to rotate.

[0014] Preferably, the cooling water pipe is arranged in a coiled shape around the power conversion module in the fuselage.

[0015] By adopting the above solution, the coiled cooling water pipe has a large contact surface with the air and a good cooling effect.

[0016] Preferably, the cooling water pipes are fixedly connected with heat exchange fins at positions close to the power supply conversion modules.

[0017] By adopting the above solution, the heat exchange fins further increase the heat exchange effect of the cooling water pipe.

[0018] Preferably, the water outlet pipe is fixedly connected to the bottom of the evaporation box, and the steam pipe is fixedly connected to the top of the evaporation box.

[0019] By adopting the above solution, the water outlet pipe guides water into the bottom of the evaporator, which is conducive to accelerating the flow of water inside the evaporator and thus accelerating the evaporation rate. It can also pressurize the inside of the evaporator, and the steam pipe receives the steam floating up at the top.

[0020] Preferably, a heat-insulating layer is fixedly connected to the outside of the evaporator box, and the heat-insulating layer covers the outer surface of the evaporator box.

[0021] By adopting the above solution, the thermal insulation layer reduces the heat leakage of the evaporation box and accelerates the evaporation rate of water.

[0022] Preferably, a heat-conducting fan directed downward is fixedly connected to the interior of the evaporator near the heat-conducting plate.

[0023] By adopting the above solution, since hot air tends to gather upwards, the heat-conducting fan blows the hot air downwards, thereby accelerating the heat absorption of the water in the evaporation box.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. During water cooling, the higher the ambient temperature, the more frequently the cooling fan starts, and the better the heat dissipation effect. It can cool the circulating water with better effect to ensure the water cooling effect. At the same time, it can also reduce the temperature of the photovoltaic panel through the heat conduction plate, which also plays a certain cooling protection effect on the photovoltaic panel.

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The embodiment of the present application discloses a power supply device with a solar power conversion circuit, such as Figure 1 and Figure 2 As shown, it includes a fuselage 1, a photovoltaic panel 2 fixedly connected to the outside of the fuselage 1, and a power conversion module 3 fixedly arranged in the fuselage 1.

[0036] like Figure 2 and Figure 3 As shown, the power conversion module 3 includes an inverter 31 electrically connected to the photovoltaic panel 2, a voltage regulator 32 electrically connected to the inverter 31, and an AC / DC transformer 33 electrically connected to the voltage regulator 32. The DC power generated by the photovoltaic panel 2 is converted into AC power by the inverter 31, stabilized by the voltage regulator 32, and finally converted into high-voltage and stable DC power by the AC / DC transformer 33 for transmission.

[0037] like Figure 2 and Figure 4As shown, a cooling water pipe 11 is fixedly connected to the fuselage 1 and arranged in a coiled shape around the power conversion module 3. Heat exchange fins 112 are fixedly connected to the cooling water pipe 11 near the power conversion module 3. The heat exchange fins 112 extend from both ends of the cooling water pipe 11. One end of the cooling water pipe 11 is fixedly connected to the water inlet pipe 12, and the other end is fixedly connected to the water outlet pipe 13. The water outlet pipe 13 is fixedly connected to the evaporator 4, which is fixedly connected to the bottom of the evaporator 4. The evaporator 4 is mounted at the bottom of the photovoltaic panel 2. A heat conducting plate 41 is fixedly connected to the top of the evaporator 4, which abuts the bottom of the photovoltaic panel 2. The heat conducting plate 41 can abut multiple photovoltaic panels 2 to improve the heating effect. An insulation layer 43 is fixedly connected to the outside of the evaporator 4, covering the outer surface of the evaporator 4. A downward-facing heat-conducting fan 44 is fixedly connected to the interior of the evaporator 4, near the heat-conducting plate 41. This fan 44 is located at the top center of the evaporator 4, ensuring that the air blown by the fan 44 does not affect the entry of steam into the evaporation duct. Water heated within the fuselage 1 enters the evaporator 4, where it receives heat from the photovoltaic panels 2 via the heat-conducting plate 41, causing the water to continuously evaporate into water vapor within the evaporator 4. Since hot air tends to accumulate upward, the heat-conducting fan 44 blows the hot air downward, accelerating the absorption of heat by the water within the evaporator 4. The insulation layer 43 reduces heat leakage from the evaporator 4, accelerating the evaporation of water.

[0038] like Figure 5 and Figure 6 As shown, the evaporator 4 is fixedly connected to a steam pipe 42, which is fixedly connected to the top of the evaporator 4. The steam pipe 42 is fixedly connected to a solenoid valve 421 and a compressor 422. The other end of the steam pipe 42 is fixedly connected to a turbine 5. The turbine 5 includes a housing 51 fixedly connected to the steam pipe 42. A rotor 52 is rotatably connected within the housing 51. The rotor 52 is fixedly connected to turbine blades 53. The rotor 52 is fixedly connected to a transmission rod 15, and the turbine 5 drives the transmission rod 15 to rotate. A cooling water pipe 11 is fixedly connected to the end of the housing 51 away from the steam pipe 42. The fuselage 1 is provided with a cooling fan 14, and the transmission rod 15 is fixedly connected to the cooling fan 14. The turbine 5 is fixedly connected to a return water pipe 61, the other end of which is fixedly connected to the cooling water tank 6. The cooling water pipe 11 is fixedly connected to the cooling water tank 6 and is fixedly connected to a water pump 111. After a certain amount of steam has accumulated or after a certain period of time, the operator opens solenoid valve 421, allowing the steam to enter compressor 422. After compression, the steam enters turbine 5, driving rotor 52. At the same time, the steam energizes turbine blades 53 and turns back into condensed water, which flows back into cooling water tank 6 through return pipe 61. Turbine 5 can use a small steam turbine, or cooling fan 14 and turbine 5 can use an integrated turbo blower, which can be retrofitted to the side wall of fuselage 1.

[0039] The implementation principle of a power supply device with a solar power conversion circuit in an embodiment of the present application is as follows: the cooling water pipe 11 allows water to flow through the inside of the fuselage 1, and cooperates with the cooling fan 14 to cool and dissipate heat from the inside of the fuselage 1. After absorbing heat, the water flows into the evaporator 4. Since the back of the photovoltaic panel 2 has an extremely high temperature, the evaporator 4 absorbs the temperature of the back of the photovoltaic panel 2 through the heat conducting plate 41, thereby accelerating the evaporation of water in the evaporator 4. The evaporated water vapor enters the compressor 422 through the steam pipe 42. The user can control the amount of steam entering the compressor 422 by controlling the solenoid valve 421 to avoid the turbine 5 from failing to work due to insufficient steam. After compressing a certain amount of steam, the compressor 422 introduces the steam into the turbine 5. The turbine 5 drives the cooling fan 14 to rotate. The condensed water then flows back to the cooling water tank 6 through the return water pipe 61 to be cooled and then pumped into the cooling water pipe 11 by the water pump 111 for circulation. The higher the ambient temperature, the more frequently the cooling fan 14 is started, and the better the cooling effect. At the same time, the temperature of the photovoltaic panel 2 can be lowered through the heat conducting plate 41, which also has a certain cooling protection effect on the photovoltaic panel 2.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
