Description

Technical Field

[0002] A photovoltaic (PV) power generation system is a power generation system that utilizes the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of a PV power generation system comes from the inexhaustible solar energy. The PV power generation process does not pollute the environment or damage the ecosystem. While the PV system converts solar radiation energy into electrical energy for storage, the electrical components (wires, circuit boards, batteries, etc.) need cooling systems to dissipate the heat generated during operation, thus improving the safety of the device. Traditionally, a mesh surface is installed on the device, utilizing passive ventilation for heat dissipation. However, the heat dissipation effect is not ideal, especially in summer, making rapid and efficient heat dissipation inconvenient and reducing the device's performance. Summary of the Invention

[0012] In one embodiment, the heat dissipation mechanism further includes a plurality of heat sinks, which are evenly spaced outside the housing, and the heat exchange tubes are thermally connected to the heat sinks.

[0013] In one embodiment, all or part of the heat sinks are located outside the first fan.

[0014] In one embodiment, the system further includes two cooling components. The box has openings at both the left and right ends, and the two cooling components are located at the openings at the left and right ends of the box, respectively.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0031] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0032] See Figures 1-3 This application provides a photovoltaic energy storage device with active heat dissipation function, mainly including a housing 1, a photovoltaic panel 2, and an active heat dissipation mechanism 3. The photovoltaic panel 2 is installed on the outside of the housing 1 to convert light energy into electrical energy. The heat dissipation mechanism 3 includes a first fan 306 and a second fan 307; mounting holes 301 are provided on both the front and rear walls of the housing 1, and the first fan 306 and the second fan 307 are respectively installed in the corresponding mounting holes 301. In use, when the internal temperature of the housing 1 is not high, passive ventilation through the mounting holes 301 is sufficient to meet the heat dissipation requirements; when the internal temperature of the housing 1 is too high and passive heat dissipation is insufficient, the fans (first fan 306 and second fan 307) can be turned on to actively expel the hot air inside the housing 1, achieving active and rapid heat dissipation.

[0033] It should be noted that the first fan 306 and the second fan 307 can be turned on simultaneously or individually, depending on the internal temperature of the cabinet 1.

[0034] It should be noted that the first fan 306 and the second fan 307 can be connected to an energy storage device for power, or they can be connected to a power supply device or the power grid. These are all conventional power extraction methods, so they will not be described in detail in this article.

[0035] It is understandable that the electrical components related to energy storage (such as wires, circuit boards, batteries, etc.) are installed inside the enclosure 1 and are electrical components that require heat dissipation.

[0036] In some embodiments, to prevent dust and debris from entering the housing 1, filters 302 can be installed at both ends or one end of the mounting hole 301. When filters 302 are installed at both ends of the mounting hole 301, the fans (first fan 306, second fan 307) are located between the two filters 302, which can also prevent dust from accumulating on the fan blades and affecting the heat dissipation effect. When filters 302 are installed at one end of the mounting hole 301, it is recommended to install them on the inside of the fan.

[0037] In some embodiments, for rapid and efficient heat dissipation, the first fan 306 can be configured to blow air out of the housing 1, and the second fan 307 can be configured to blow air into the housing 1. The first fan 306 can transfer heat inside the housing 1, and the second fan 307 blows air from outside the housing 1 into the housing 1 to dissipate heat from the photovoltaic energy storage device. In conjunction with the first fan 306, the airflow inside the housing 1 can be improved, enabling rapid and efficient heat dissipation from the photovoltaic energy storage device during operation.

[0038] It is understandable that the direction of airflow from a fan can be controlled by adjusting the direction of the fan blades, adjusting the direction of the motor rotation, or using a reversing gear set. These are all conventional technical means in the existing technology, so they will not be elaborated further.

[0039] In some embodiments, to enhance heat dissipation, our heat dissipation mechanism 3 may further include a heat-conducting plate 303 and a heat exchange pipe 304. The heat-conducting plate 303 is located inside the housing 1, close to the electrical components. One end of the heat exchange pipe 304 is thermally connected to the heat-conducting plate 303, and the other end is located outside the first fan 306. The heat generated by the electrical components is transferred to the heat-conducting plate 303 nearby, and then discharged outside the housing 1 by the first fan 306 through the heat exchange pipe 304.

[0040] In some embodiments, to further enhance the heat dissipation effect, our heat dissipation mechanism 3 may also include a plurality of heat sinks 305. The plurality of heat sinks 305 are evenly spaced outside the housing 1, and the heat exchange pipe 304 is thermally connected to the heat sinks 305. The heat dissipation effect is improved by increasing the heat dissipation area through the plurality of heat sinks 305.

[0041] Furthermore, all or part of the heat sinks 305 are located outside the first fan 306, which can also utilize the airflow effect of the first fan 306 to accelerate heat dissipation.

[0042] In some embodiments, in order to further improve the heat dissipation effect, any of the above-mentioned photovoltaic energy storage devices with active heat dissipation function also includes two cooling components 309, which are respectively installed at the openings at the left and right ends of the housing 1 (of course, the left and right ends of the housing 1 need to be open). The two cooling components 309 at the left and right ends of the housing 1, together with the first fan 306 and the second fan 307 on the front and rear sides of the housing 1, dissipate heat from the four sides of the housing 1 to maximize the heat dissipation effect.

[0043] Specifically, the cooling component 309 mainly includes a mounting plate 3091 and a heat dissipation mesh 3093. The heat dissipation mesh 3093 is installed on one side of the mounting plate 3091. The mounting plate 3091 is slidably fitted with the inner wall of the housing 1, with the mounting plate 3091 located at the opening and the heat dissipation mesh 3093 located inside the housing 1. When maximum heat dissipation is required, the mounting plate 3091 is pulled out along with the heat dissipation mesh 3093, allowing the housing 1 to ventilate and dissipate heat from both ends. When not in use, the mounting plate 3091 closes the opening, and the heat dissipation mesh 3093 is entirely located inside the housing 1.

[0044] Furthermore, a slider 3094 is provided at the bottom of the mounting plate 3091, and a corresponding sliding groove is provided at the bottom of the housing 1, with the slider 3094 slidingly engaging with the sliding groove. A lead screw 3096 is counterweighted within the sliding groove, and a motor 3097 is mounted on the housing 1. The motor 3097 is connected to the lead screw 3096, and the lead screw 3096 is threadedly connected to the slider 3094. By configuring the motor 3097, lead screw 3096, and slider 3094 to work together, starting the motor 3097 allows for the automatic insertion and removal of the cooling component 309.

[0045] Furthermore, the heat dissipation mesh 3093 is a ring-shaped flexible metal mesh with a fixing plate 3092 at the opening. The two ends of the flexible metal mesh are fixedly connected to the fixing plate 3092 and the mounting plate 3091, respectively. The flexible metal mesh can be unfolded and folded when the cooling component 309 is inserted or removed, and it always remains at the opening without encroaching on the internal space of the housing 1, allowing the photovoltaic energy storage device to be made smaller.

[0046] In some embodiments, a temperature sensor 308 is provided inside the housing 1 to monitor the temperature inside the housing 1. The cooling component 309 and the heat dissipation mechanism 3 can be turned on or off based on the real-time temperature.

[0047] In summary, the beneficial effects of this utility model mainly include:

[0048] (1) By setting up the heat dissipation mechanism 3, when the photovoltaic energy storage device is cooled, the temperature sensor 308 can accurately detect the temperature of the photovoltaic energy storage device to prevent the device from being damaged due to excessive temperature; the heat conduction plate 303 can guide the heat generated by the device, and then the heat exchange tube 304 conducts heat dissipation to cool down the photovoltaic energy storage device; one end of the heat exchange tube 304 cooperates with the heat sink 305 to improve the heat dissipation effect of the device; the rotation of the first fan 306 can transport the heat inside the box 1, and the second fan 307 blows the air outside the box 1 into the box 1 to cool down the photovoltaic energy storage device. The second fan 307 cooperates with the first fan 306 to improve the air flow inside the box 1. The filter screen 302 can prevent dust from entering the box 1 and can quickly and efficiently dissipate the heat generated by the photovoltaic energy storage device during operation, thereby improving the safety of the device.

[0049] (2) By setting the cooling component 3, when the photovoltaic energy storage device is cooled, the motor 3097 drives the lead screw 3096 to rotate. The lead screw 3096 and the slider 3094 cooperate to drive the mounting plate 3091 to move. The mounting plate 3091 drives the heat dissipation mesh 3093 to open from the fixed plate 3092 to cool the photovoltaic energy storage device and improve the ventilation effect of the device. The heat dissipation mesh 3093 is a flexible metal mesh that can quickly diffuse heat and prevent dust from entering the box 1. It can quickly cool the photovoltaic energy storage device and improve the ventilation of the device.
