[0002] As global awareness of climate change grows, more and more households and individuals are turning to renewable energy to reduce their carbon footprint. Household photovoltaic energy storage systems, as efficient and green energy solutions, are becoming a new trend in household energy consumption. As a key component of photovoltaic power generation systems, MPPT converters enable maximum power point tracking (MPPT) of photovoltaic cells. However, in high-temperature environments, such as summer, converters are prone to overheating and shutdown, resulting in the photovoltaic cells being unable to output power, seriously impacting the reliability and economic efficiency of photovoltaic power generation.

[0003] Currently, there are three main heat dissipation methods for energy storage systems: natural heat dissipation, forced air cooling, and forced liquid cooling. For small and medium-power outdoor photovoltaic energy storage systems, forced air cooling is generally used. This involves creating ventilation holes on the sides of the energy storage device and installing cooling fans inside. However, since household photovoltaic energy storage systems are typically installed outdoors, on balconies, or under roofs, heat can easily seep into the battery pack through the ventilation holes, affecting the performance of the energy storage device.

[0035] In the above-mentioned outdoor photovoltaic energy storage and heat dissipation device, the battery pack is installed inside the bottom shell, the heat dissipation top cover is arranged on the bottom shell, a heat dissipation channel is opened on the inner side of the heat dissipation top cover, and the aluminum maximum power point tracking converter is connected to the outer wall of the heat dissipation channel so that the heat of the aluminum maximum power point tracking converter is transferred to the heat dissipation channel through the outer wall of the heat dissipation channel.

[0036] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0037] like Figures 1 to 5 As shown, an outdoor photovoltaic energy storage and heat dissipation device 10 of an embodiment includes a bottom shell 100, a battery pack 200, an aluminum maximum power point tracking converter 300, a heat dissipation top cover 400, a heat dissipation fan 500, a sealing ring 600 and a protective bracket 700. The battery pack 200 is installed inside the bottom shell 100, the heat dissipation top cover 400 is covered with the opening of the bottom shell 100, and a heat dissipation channel 400a is opened on the inner side of the heat dissipation top cover 400. The aluminum maximum power point tracking converter 300 is connected to the outer wall of the heat dissipation channel 400a. The heat dissipation fan 500 is located at the heat dissipation channel 400a. The bottom shell 100 is provided with a mounting hole 110, which is arranged corresponding to the heat dissipation channel 400a. The protective bracket 700 is located in the mounting hole 110 and is connected to the bottom shell 100. The protective bracket 700 is provided with a ventilation hole 710, which is arranged corresponding to the heat dissipation channel 400a. The protective bracket 700, the heat dissipation top cover 400 and the bottom shell 100 jointly form an embedding groove 100a, and the sealing ring 600 is located in the embedding groove 100a.

[0038] In this embodiment, the aluminum maximum power point tracking converter 300 is an MPPT converter 300. The aluminum maximum power point tracking converter 300 is electrically connected to the battery pack 200 to achieve maximum power point tracking of the battery. The aluminum maximum power point tracking converter 300 is connected to the outer wall of the heat dissipation channel 400a. The heat generated by the aluminum maximum power point tracking converter 300 during operation is transferred to the heat dissipation channel 400a and is cooled by the heat dissipation fan 500 in the heat dissipation channel 400a. When the heat dissipation fan 500 is started, the air in the heat dissipation channel 400a is circulated with the outside air through the heat dissipation holes, thereby achieving heat exchange and improving the heat dissipation performance of the device. Furthermore, the protective bracket 700 presses the sealing ring 600 so that the sealing ring 600 abuts against the heat dissipation top cover 400 and the bottom shell 100. The protective bracket 700 is fastened to the bottom shell 100 by screws. At this time, the protective bracket 700, the heat dissipation top cover 400 and the bottom shell 100 jointly form an embedding groove 100a. The sealing ring 600 is located in the embedding groove 100a, so that rainwater in the ventilation hole 710 and the mounting hole 110 is blocked by the sealing ring 600, that is, rainwater cannot penetrate into the battery pack 200 at the bottom, thereby improving the waterproof performance.

[0039] In the outdoor photovoltaic energy storage and heat dissipation device 10, the battery pack 200 is installed inside the bottom shell 100, the heat dissipation top cover 400 is covered on the bottom shell 100, and the inner side of the heat dissipation top cover 400 is provided with a heat dissipation channel 400a. The aluminum maximum power point tracking converter 300 is connected to the outer wall of the heat dissipation channel 400a, so that the heat of the aluminum maximum power point tracking converter 300 is transferred to the heat dissipation channel 400a through the outer wall of the heat dissipation channel 400a. A heat dissipation fan 500 is provided in the heat dissipation channel 400a, and the heat dissipation fan 500 is arranged toward the heat dissipation hole to accelerate the air circulation speed in the heat dissipation channel 400a, thereby improving the heat dissipation of the heat dissipation channel 400a. The heat dissipation performance of the device is improved, and since the heat dissipation channel 400a is hidden in the inner side of the heat dissipation top cover 400, the overall external structure of the device is more beautiful; since the protective bracket 700 is installed in the mounting hole 110 of the bottom shell 100, the heat dissipation hole of the protective bracket 700 is corresponding to the heat dissipation channel 400a, the protective bracket 700, the heat dissipation top cover 400 and the bottom shell 100 jointly form an embedding groove 100a, and the sealing ring 600 is located in the embedding groove 100a to improve the waterproof performance of the mounting hole 110 and the heat dissipation hole, so that rainwater cannot reach the battery pack 200 in the bottom shell 100, thereby extending the service life of the device.

[0040] like Figure 5 and Figure 6As shown, in one embodiment, the sealing ring 600 includes a first sealing body 610 and a second sealing body 620 connected to each other. The first sealing body 610 is clamped and abutted between the heat dissipation top cover 400 and the protective bracket 700, and the second sealing body 620 is clamped and abutted between the bottom shell 100 and the protective bracket 700. It can be understood that the first sealing body 610 and the second sealing body 620 are an integrally formed structure. The first sealing body 610 is perpendicular to the second sealing body 620. The first sealing body 610 is clamped and abutted between the heat dissipation top cover 400 and the protective bracket 700 to prevent rainwater entering through the heat dissipation holes from penetrating into the battery pack 200. The second sealing body 620 is clamped and abutted between the bottom shell 100 and the protective bracket 700 to prevent rainwater at the rainwater installation hole 110 from penetrating into the battery pack 200.

[0041] like Figure 7 As shown, in one embodiment, the heat dissipation top cover 400 includes a top cover body 410, a plurality of first heat dissipation fins 420, and a plurality of second heat dissipation fins 430. The heat dissipation channel 400a is opened in the top cover body 410. The plurality of first heat dissipation fins 420 are spaced apart on a side of the top cover body 410 facing away from the battery pack 200. The plurality of second heat dissipation fins 430 are spaced apart on the inner wall of the heat dissipation channel 400a. It can be understood that the plurality of second heat dissipation fins 430 are spaced apart on the inner wall of the heat dissipation channel 400a. When heat is transferred from the outer wall of the heat dissipation channel 400a to the heat dissipation channel 400a, the second heat dissipation fins 430 increase the heat dissipation area within the heat dissipation channel 400a, thereby improving the heat dissipation performance of the device. Furthermore, multiple first heat dissipation fins 420 are spaced apart on a side of the top cover body 410 facing away from the battery pack 200, that is, the first heat dissipation fins 420 are arranged on the top surface of the top cover body 410. The first heat dissipation fins 420 increase the heat dissipation area of ​​the top cover body 410 and further improve the heat dissipation performance of the device.

[0042] In one embodiment, the top cover body 410, the first heat sink fins 420, and the second heat sink fins 430 are integrally formed. In this embodiment, the top cover body 410, the first heat sink fins 420, and the second heat sink fins 430 are integrally stamped, making the heat sink 400 more compact and stronger. Furthermore, the heat sink 400 is made of aluminum, which provides better heat dissipation.

[0043] like Figure 3 As shown, in one embodiment, the number of the heat dissipation fans 500 is two, and the two heat dissipation fans 500 are respectively located at two ends of the heat dissipation channel 400a; and,

[0044] The number of the mounting holes 110 , the sealing rings 600 , and the protective brackets 700 is also two, and one sealing ring 600 and one protective bracket 700 are disposed in each mounting hole 110 .

[0045] In this embodiment, two cooling fans 500 are provided, one at each end of the heat dissipation channel 400a, to enhance heat exchange between the heat dissipation top cover 400 and the outside air. Accordingly, two mounting holes 110 are provided on either side of the bottom case 100. Each mounting hole 110 houses a sealing ring 600 and a protective bracket 700. The sealing ring 600 ensures a tight seal at the mounting hole 110, while the protective bracket 700 protects the cooling fans 500. The protective bracket 700 also features cooling holes, allowing the heat dissipation channel 400a to circulate with the outside air through these holes.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the heat dissipation channel 400a is extended along the length direction of the top cover body 410. It can be understood that the heat dissipation channel 400a is extended along the length direction of the top cover body 410, that is, the heat dissipation channel 400a is relatively long, so that both ends of the heat dissipation channel 400a are adjacent to the heat dissipation holes of the protective bracket 700, thereby allowing the heat in the heat dissipation channel 400a to be better exchanged with the outside air through the heat dissipation holes.

[0047] like Figure 3 As shown, in one embodiment, the aluminum MPPT converter 300 is bonded to the outer wall of the heat dissipation channel 400a via thermally conductive silicone 310. In this embodiment, the aluminum MPPT converter 300 is bonded to the outer wall of the heat dissipation channel 400a via thermally conductive silicone 310. The thermally conductive silicone 310 has excellent thermal conductivity, allowing heat from the aluminum MPPT converter 300 to be better transferred into the heat dissipation channel 400a.

[0048] like Figure 3 As shown, in one embodiment, the aluminum MPPT converter 300 is connected to the middle of the outer wall of the heat dissipation channel 400a. As will be appreciated, this connection allows the heat generated by the aluminum MPPT converter 300 to be more evenly transferred to the interior of the heat dissipation channel 400a. Heat is then exchanged with the outside air via the cooling fans 500 at both ends, resulting in better heat dissipation.

[0049] like Figure 2 and Figure 3As shown, in one embodiment, the bottom shell 100 is provided with a mounting groove 120, and the mounting hole 110 is provided on the bottom wall of the mounting groove 120. It can be understood that the bottom shell 100 is partially recessed inward to form the mounting groove 120, and the mounting hole 110 is provided on the bottom wall of the mounting groove 120. The protective bracket 700 is installed in the mounting hole 110, that is, the peripheral wall of the mounting groove 120 protrudes from the protective bracket 700, so that the mounting groove 120 plays a role in initially blocking rainwater, and at the same time, the protective bracket 700 does not protrude from the surface of the bottom shell 100, so as to avoid the protective bracket 700 scratching the user. Furthermore, an electrical connection port is also provided in the mounting groove 120, so that an external device can be electrically connected to the battery pack 200 through the electrical connection port.

[0050] The present application also provides an energy storage device, comprising the outdoor photovoltaic energy storage and heat dissipation device 10 described in any of the above embodiments.

[0051] Compared with the prior art, the present disclosure has at least the following advantages:

[0052] In the outdoor photovoltaic energy storage and heat dissipation device 10, the battery pack 200 is installed inside the bottom shell 100, the heat dissipation top cover 400 is covered on the bottom shell 100, and the inner side of the heat dissipation top cover 400 is provided with a heat dissipation channel 400a. The aluminum maximum power point tracking converter 300 is connected to the outer wall of the heat dissipation channel 400a, so that the heat of the aluminum maximum power point tracking converter 300 is transferred to the heat dissipation channel 400a through the outer wall of the heat dissipation channel 400a. A heat dissipation fan 500 is provided in the heat dissipation channel 400a, and the heat dissipation fan 500 is arranged toward the heat dissipation hole to accelerate the air circulation speed in the heat dissipation channel 400a, thereby improving the heat dissipation of the heat dissipation channel 400a. The heat dissipation performance of the device is improved, and since the heat dissipation channel 400a is hidden in the inner side of the heat dissipation top cover 400, the overall external structure of the device is more beautiful; since the protective bracket 700 is installed in the mounting hole 110 of the bottom shell 100, the heat dissipation hole of the protective bracket 700 is corresponding to the heat dissipation channel 400a, the protective bracket 700, the heat dissipation top cover 400 and the bottom shell 100 jointly form an embedding groove 100a, and the sealing ring 600 is located in the embedding groove 100a to improve the waterproof performance of the mounting hole 110 and the heat dissipation hole, so that rainwater cannot reach the battery pack 200 in the bottom shell 100, thereby extending the service life of the device.

[0053] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
