Description

Technical Field

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

[0002] In the current global off-grid photovoltaic market, especially in Africa and Southeast Asia, the mainstream inverters generally adopt the IP21 protection level, which can only protect against vertical dripping and large dust particles. The overall structural design has the following common defects: (1) Since the shell is a single-layer sheet metal shell and is fixed by screws, the overall gap width is ≥1.2mm, which cannot block the intrusion of dust particles with a diameter ≤1mm, resulting in a short circuit failure rate of 15%-20% for the circuit board; (2) Since the exposed terminals or ordinary plastic covers are used without waterproofing, the water seepage rate at the interface reaches 35% in the rainy season, which can easily cause damage to the internal circuit. (3) In order to reduce costs, some inverters adopt open heat dissipation holes without designing a protective structure. Although the heat dissipation efficiency is guaranteed, the protection performance is sacrificed. If upgraded to IP65 level, the power device and heat sink need to be designed separately, which increases the material cost by 40%-60%, which cannot meet the market demand for high cost performance. Summary of the Invention

[0003] To solve the above problems, the present invention adopts the following technical solution: an energy-saving heat dissipation inverter, comprising: a housing, a top cover, a first side cover, a second side cover, and a heat dissipation assembly;

[0024] The technical solutions of the present invention will be further described below with reference to the accompanying drawings of the embodiments of the present invention. The present invention is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0025] like Figures 1 to 7 As shown, an energy-saving heat dissipation 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 mesh 510, a second heat dissipation mesh 520, and two heat sinks 530. The first heat dissipation mesh 510 is disposed at one end of the housing 100, the second heat dissipation mesh 520 is disposed at the other end of the housing 100, and both heat sinks 530 are disposed inside 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 against 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 mesh 510.

[0026] Specifically, the housing 100 is provided with two sealing strips 600. One side of the first side cover 300 is sealed to the housing 100 via one of the sealing strips 600, and the other side is sealed to the housing 100 via another sealing strip 600. The housing 100 is provided with two water receiving grooves 700, both of which are located at the bottom of the inner side of the housing 100 and are correspondingly arranged. Each water receiving groove 700 has a plurality of water outlet holes at its bottom, which are equidistant from each other. Further, the heat dissipation assembly also includes a mounting plate 800, one end of which is detachably mounted on the top of one water receiving groove 700, and the other end of which is detachably mounted on the top of the other water receiving groove 700. Both radiators 530 are mounted on the mounting plate 800. In other words, the interior of the housing 100 is separated by the mounting plate 800. The area covered by the first side cover 300 is used to place various components required by the inverter, and the area covered by the second side cover 400 is the wiring area. This means that staff or users can connect and conduct wires to the components through the wiring area.

[0027] In one embodiment, the first side cover 300 is provided with a plurality of first insert blocks 310, and the first heat dissipation mesh 510 is provided with a plurality of first sockets, each of the first insert blocks 310 being movably fastened into a first socket. The second side cover 400 is provided with a plurality of second insert blocks 410, and the second heat dissipation mesh 520 is provided with a plurality of second sockets, each of the second insert blocks 410 being movably fastened into a second socket.

[0028] In another embodiment, a baffle plate 900 is provided at one end of the housing 100, the baffle plate 900 being located between the top cover 200 and the first heat dissipation mesh 510. Further, 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 passed through the first vertical plate 320 and screwed onto the top cover 200. First, the first side cover 300 is connected to the top cover 200, and then the first side cover 300 and the top cover 200 are installed together on the housing 100. At this time, a sealing strip 600 abuts against each side of the first side cover 300, thus providing a good waterproof seal. The first side cover 300 is then fixed to the housing 100 with screws. It is worth mentioning that when the first side cover 300 is connected to the housing 100, each first insert 310 on the first side cover 300 is inserted into a first socket on the first heat dissipation mesh 510, thus providing a good connection and fixation. Furthermore, after the first side cover 300 is connected, there is a certain distance between the top cover 200 and the first heat dissipation mesh 510. This means that the top cover 200 can prevent external water from entering the inverter's interior through the first heat dissipation mesh 510 without affecting internal heat dissipation. Although there is a gap on one side between the top cover 200 and the first heat dissipation mesh 510, since this side is located on the side of the wall during installation, water will not directly enter through the gap. Furthermore, a baffle plate 900 is installed at this gap, and the height of the baffle plate 900 is higher than the position of the first heat dissipation mesh 510. Even if water flows down from the top cover 200, the baffle plate 900 can effectively block the water, and the water will flow down along the baffle plate 900.

[0030] Furthermore, after the first side cover 300 and the top cover 200 are connected, there is still a gap between them. By designing the first vertical plate 320, and ensuring that the vertical height of the first vertical plate 320 is higher than the position of the first heat dissipation mesh 510, even if water flows down from the top cover 200 into the gap between it and the first side cover 300, it will not enter the interior of the housing 100. Moreover, since the first vertical plate 320 is located on the first side cover 300, and the connection between the first vertical plate 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 point.

[0031] Similarly, in the above embodiments, after the first side cover 300 and the second side cover 400 are connected, there is also a gap between them. By designing the second vertical plate 420, which abuts against the edge of the internal mounting plate 800, water flowing down from the first side cover 300 can be prevented from directly entering the interior of the housing 100 through the gap between it and the second side cover 400. Furthermore, an inclined portion 430 is provided at the connection between the second vertical plate 420 and the second side cover 400, and the inclined portion 430 is inclined from the middle to both sides. It is worth mentioning that each water receiving groove 700 has a water inlet 710, and each water receiving groove 700 abuts against the inclined portion 430. In other words, the center of the inclined section 430 is the highest point, and both ends are the lowest points. Each water receiving trough 700 is located on one side of the lowest point, and the lowest point is exactly next to a water inlet 710. That is, water flowing down from the first side cover 300 enters the gap between the first side cover 300 and the second side cover 400, flows along the inclined section 430 to both ends, and finally enters a water receiving trough 700 through any water inlet 710, and then flows out through the water outlet at the bottom of the water receiving trough 700. More importantly, by setting two water receiving troughs 700, the two sides of the mounting plate 800 can be directly installed on the top of the two water receiving troughs 700. Therefore, the mounting plate 800 does not need to be locked to the housing 100, that is, it does not need to be fixed to the mounting plate 800 from the outside with screws, making the overall appearance more aesthetically pleasing.

[0032] In the above embodiment, by using a first heat dissipation mesh 510, a second heat dissipation mesh 520, and two heat sinks 530 (which are cooling fans), when heat dissipation is required, the two cooling fans are activated. At this time, the cooling fans blow the air inside the housing 100 upwards. That is, external air enters the area covered by the second side cover 400 through the second heat dissipation mesh 520, and then, following the airflow direction of the cooling fans, enters the area covered by the first side cover 300. The hot air from the area covered by the first side cover 300 is blown out through the first heat dissipation mesh 510 and then out through the gap formed between the top cover 200 and the first heat dissipation mesh 510. It is worth mentioning that both the first heat dissipation mesh 510 and the second heat dissipation mesh 520 are provided with a dustproof cotton 550. This means that the dustproof cotton 550 does not block the heat dissipation holes on the first heat dissipation mesh 510 or the second heat dissipation mesh 520, but it provides excellent dust protection. Therefore, there is no need to worry about external dust entering the interior of the housing 100 and affecting the inverter's operation.

[0033] In other words, since this energy-saving and heat-dissipating inverter is primarily used in Africa, it is an IP54 inverter overall. Compared to the traditional IP65 inverter, which is too expensive due to its compartmentalized design, this energy-saving and heat-dissipating inverter is more economical and affordable for users. Furthermore, it provides excellent waterproofing and heat dissipation, eliminating the need to add additional heatsinks (530) to improve overall heat dissipation performance. This effectively avoids the noise issues that would arise from adding heatsinks (530) and disrupt users' daily lives.

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