Description

Technical Field

[0001] The present invention relates to the field of inverters, and in particular to an energy-saving and heat-dissipating inverter. Background Art

[0002] In the current global off-grid photovoltaic market, especially in Africa and Southeast Asia, mainstream inverters generally adopt an IP21 protection level that can only protect against vertical dripping and large dust particles. The overall structural design has the following common defects: (1) Since the shell adopts a single-layer sheet metal shell and is fixed by screws, the overall gap width is ≥1.2mm, which cannot prevent the intrusion of dust particles with a diameter of ≤1mm, resulting in a circuit board short circuit failure rate as high as 15%-20%; (2) Since exposed terminals or ordinary plastic covers are used without waterproofing, the water seepage rate at the interface reaches 35% under continuous rainfall in the rainy season, which can easily cause damage to the internal circuit. (3) In order to reduce costs, some inverters use open heat dissipation holes and no protective structure. Although the heat dissipation efficiency is guaranteed, the protection performance is sacrificed. If it is upgraded to IP65 level, the power device and heat sink must be separated into compartments, resulting in a 40%-60% increase in material costs, which cannot meet the market demand for high cost performance.

[0024] The following will further describe the technical solution of the present invention in conjunction with the drawings of the embodiments of the present invention. The present invention is not limited to the following specific implementation methods. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0025] like Figures 1 to 7 As shown, an energy-saving and heat-dissipating inverter includes: a housing 100, a top cover 200, a first side cover 300, a second side cover 400, and a heat dissipation assembly; the heat dissipation assembly includes a first heat dissipation net 510, a second heat dissipation net 520, and two radiators 530, wherein the first heat dissipation net 510 is arranged at one end of the housing 100, the second heat dissipation net 520 is arranged at the other end of the housing 100, and the two radiators 530 are both arranged in the housing 100; the first side cover 300 and the second side cover 400 both cover the side of the housing 100, and the first side cover 300 abuts the second side cover 400; the top cover 200 covers one end of the housing 100, and the top cover 200 is spaced apart from the first heat dissipation net 510.

[0026] Specifically, the shell 100 is provided with two sealing strips 600, and one side of the first side cover 300 is sealedly connected to the shell 100 through one sealing strip 600, and the other side is sealedly connected to the shell 100 through another sealing strip 600. The shell 100 is provided with two water receiving grooves 700, and the two water receiving grooves 700 are both arranged at the bottom of the inner side of the shell 100, and the two water receiving grooves 700 are arranged correspondingly. A plurality of water outlet holes are provided at the bottom of each water receiving groove 700, and the plurality of water outlet holes are equidistantly provided. Furthermore, the heat dissipation assembly also includes a mounting plate 800, one end of the mounting plate 800 is detachably provided on the top of one water receiving groove 700, and the other end is detachably provided on the top of the other water receiving groove 700, and the two radiators 530 are both arranged on the mounting plate 800. That is to say, the interior of the shell 100 is separated by the mounting plate 800, the area covered by the first side cover 300 is used to place various components required for the inverter, and the area covered by the second side cover 400 is the wiring area, that is, the staff or user can connect the components by wiring in the wiring area.

[0027] In one embodiment, the first side cover 300 is provided with a plurality of first inserting blocks 310, and the first heat dissipation net 510 is provided with a plurality of first sockets, each of which is movably engaged with one of the first sockets. The second side cover 400 is provided with a plurality of second inserting blocks 410, and the second heat dissipation net 520 is provided with a plurality of second sockets, each of which is movably engaged with one of the second sockets.

[0028] In another embodiment, a water baffle 900 is provided at one end of the housing 100, and the water baffle 900 is located between the top cover 200 and the first heat dissipation net 510. Furthermore, a first vertical plate 320 is provided on the first side cover 300, and the first side cover 300 is connected to the top cover 200 via the first vertical plate 320. A second vertical plate 420 is provided on the second side cover 400, and the second side cover 400 is connected to the first side cover 300 via the second vertical plate 420.

[0029] During assembly, screws are inserted through the first riser 320 and then screwed onto the top cover 200. First, the first side cover 300 is connected to the top cover 200. Then, the first side cover 300 and the top cover 200 are installed together on the housing 100. At this point, both sides of the first side cover 300 abut against a sealing strip 600, providing a good waterproof seal. The first side cover 300 is then secured to the housing 100 using screws. It is worth noting that when the first side cover 300 is connected to the housing 100, each first insert 310 on the first side cover 300 inserts into a first socket on the first heat sink 510, effectively securing the connection. Furthermore, after the first side cover 300 is connected, a certain distance remains between the top cover 200 and the first heat sink 510. This means that the top cover 200 prevents external water from entering the inverter through the first heat sink 510 while also preventing internal heat dissipation. Although there is a gap on one side between the top cover 200 and the first heat dissipation network 510, since the side where the gap is located is located on the edge of the wall during installation, no water will enter directly from the gap. In addition, a water baffle 900 is provided in the gap. The height of the water baffle 900 is higher than the position where the first heat dissipation network 510 is located. Even if water flows down from the top cover 200, the water baffle 900 can well block the water, and then the water will flow down along the water baffle 900.

[0030] Furthermore, after the first side cover 300 and the top cover 200 are connected, a gap still exists between them. However, by designing the first riser 320 and setting the first riser 320 higher than the location of the first heat dissipation mesh 510, even if water flows down along the top cover 200 and into the gap between the top cover 200 and the first side cover 300, it will not enter the interior of the housing 100. Furthermore, because the first riser 320 is disposed on the first side cover 300 and the connection between the first riser 320 and the first side cover 300 has a certain curvature, water will flow down along this curvature, that is, from the outside of the first side cover 300, and will not accumulate at the connection.

[0031] Similarly, in the above embodiment, after the first side cover 300 and the second side cover 400 are connected, a gap exists between them. By designing the second riser 420, the second riser 420 abuts the edge of the internal mounting plate 800, thereby preventing water flowing down from the first side cover 300 from directly entering the interior of the housing 100 through the gap between the second side cover 400 and the second side cover 400. Furthermore, an inclined portion 430 is provided at the connection between the second riser 420 and the second side cover 400, and the inclined portion 430 is inclined from the center to both sides. It is worth mentioning that each water receiving trough 700 has a water receiving port 710, and each water receiving trough 700 abuts the inclined portion 430. That is, the center of the inclined portion 430 is the highest point, and the two ends are the lowest points. Then, each water receiving groove 700 is located on one side of the lowest point, and the lowest point is just next to a water receiving port 710. In other words, after water flowing down from the first side cover 300 enters the gap between the first side cover 300 and the second side cover 400, it will flow along the inclined portion 430 to the two ends, and finally enter one of the water receiving grooves 700 along any of the water receiving ports 710, and then flow out through the water outlet at the bottom of the water receiving groove 700. It is worth mentioning that by providing two water receiving grooves 700, the two sides of the mounting plate 800 can be directly mounted on the top of the two water receiving grooves 700. Therefore, the mounting plate 800 does not need to be locked to the housing 100, that is, there is no need to screw the mounting plate 800 from the outside, making the overall appearance more beautiful.

[0032] In the above embodiment, a first heat dissipation net 510, a second heat dissipation net 520, and two heat sinks 530 are used. The heat sinks 530 are cooling fans. When heat dissipation is required, the two cooling fans are activated, and the cooling fans blow air upward from the interior of the housing 100. In other words, external air enters the area covered by the second side cover 400 through the second heat dissipation net 520, and then enters the area covered by the first side cover 300 along the direction of the cooling fans. Hot air from the area covered by the first side cover 300 is then blown out through the first heat dissipation net 510 and then out through the gap formed between the top cover 200 and the first heat dissipation net 510. It is worth noting that dustproof cotton 550 is provided on each of the first and second heat dissipation nets 510, 520. While the dustproof cotton 550 does not block the heat dissipation holes in the first or second heat dissipation nets 510, it still effectively prevents dust from entering the interior of the housing 100 and affecting the operation of the inverter.

[0033] Because this energy-saving, heat-dissipating inverter is primarily used in Africa, it is designed as an IP54 inverter. Compared to traditional IP65 inverters, which require a separate compartment design and result in high costs, this energy-saving, heat-dissipating inverter is more affordable and user-friendly. Furthermore, it provides excellent waterproofing and heat dissipation, eliminating the need to add a heat sink 530 to improve overall heat dissipation performance. This effectively avoids the noise that would otherwise affect users' daily lives.

[0034] In summary, the above embodiments are not limitative embodiments of the present invention, and any modifications or equivalent variations made by those skilled in the art based on the essential contents of the present invention are within the technical scope of the present invention.
