[0027] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0028] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0029] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0030] The embodiment of the present utility model provides a solar inverter heat dissipation structure, such as Figure 1-6 Shown, including:

[0031] The inverter box 100 has an operation panel 110 detachably connected to the front end thereof, air inlets 120 are provided on both sides of the inverter box 100, and an air outlet 130 is provided at the bottom of the inverter box 100, and a fan 140 is provided at the air outlet 130;

[0032] The solar inverter assembly 200 is disposed in the inverter housing 100 and is provided with a first heat dissipation fin 210 and a second heat dissipation fin 220 ;

[0033] The heat dissipation cover 300 connects the first heat dissipation fins 210 , the second heat dissipation fins 220 and the air outlet 130 to form a heat dissipation duct 310 through which air can pass through the air inlet 120 , the first heat dissipation fins 210 , the second heat dissipation fins 220 and the air outlet 130 in sequence.

[0034] The front of the inverter housing 100 is detachably connected to an operation panel 110, typically secured with screws or snaps, for easy operation and maintenance. Air inlets 120 are located on both sides of the inverter housing 100, and air outlets 130 are located at the bottom to ensure proper air circulation. The air inlet 120 of the inverter housing 100 is fitted with a dust screen to prevent dust from entering the housing and facilitate cleaning. The solar inverter assembly 200 is placed within the inverter housing 100. The assembly includes electronic circuits and power devices, which generate heat during operation. First and second heat sink fins 210, 220 are installed in the heat-concentrated areas of the inverter assembly. These fins are typically made of aluminum or other high-thermal-conductivity materials to increase the heat dissipation area and improve heat dissipation efficiency. The heat shield 300 is made of a high-temperature-resistant material. Its shape and size must cover the first and second heat sink fins 210, 220 and match the internal structure of the inverter housing 100. Connect the heat shield 300 to the first and second heat sink fins 210 and 220, while ensuring that the other end of the heat shield 300 is connected to the air outlet 130 to form a sealed air passage. Install a fan 140 at the air outlet 130 to extract the hot air from the box, accelerate air flow, and improve heat dissipation efficiency.

[0035] The heat dissipation structure of the solar inverter of the present invention has the following advantages: (1) high heat dissipation efficiency, which ensures the stable operation of the solar inverter assembly 200; (2) simple structure, easy installation, and reduced production costs; (3) easy operation and maintenance, which increases the service life of the equipment; (4) the use of environmentally friendly materials is beneficial to environmental protection.

[0036] The working principle of this utility model is as follows:

[0037] When the solar inverter assembly 200 is operating, the heat generated is transferred to the heat sink fins. When the fan 140 is activated, cool air enters through the air inlet 120, passes through the first heat sink fin 210 and the second heat sink fin 220, and removes the heat. Finally, the hot air is discharged through the air outlet 130, achieving heat dissipation.

[0038] In some embodiments, the first heat dissipating fins 210 are in a rectangular parallelepiped shape.

[0039] The rectangular parallelepiped structure is relatively stable and is easy to install and fix in the heat concentration area of ​​the solar inverter assembly 200.

[0040] Furthermore, the heat dissipation cover 300 includes an open portion 320 matching the first heat dissipation fins 210 .

[0041] The shape of the open portion 320 matches the profile of the first heat dissipation fin 210 . The heat dissipation cover 300 is directly mounted on the first heat dissipation fin 210 . The first heat dissipation fin 210 is used as part of the heat dissipation cover 300 , which can effectively save materials and costs.

[0042] In some embodiments, the second heat dissipating fins 220 have multiple groups and are arranged at intervals.

[0043] Multiple sets of fins increase the heat dissipation area and improve heat exchange efficiency. The spaced-apart fins help air flow between them, reducing air resistance and improving airflow efficiency.

[0044] Furthermore, the heat dissipation cover 300 includes a blocking portion 330 for blocking the gaps between the plurality of groups of second heat dissipation fins 220 .

[0045] The blocking portion 330 can guide air to flow more efficiently within the heat dissipation duct 310, thereby improving heat dissipation efficiency. At the same time, the blocking portion 330 can prevent dust, fibers, and other debris from entering the gaps between the heat dissipation fins, which may reduce heat dissipation efficiency or even damage internal components of the device.

[0046] In some embodiments, the heat dissipation cover 300 includes a first connection portion 340 connected to the first heat dissipation fins 210 and the second heat dissipation fins 220 , and also includes a second connection portion 350 connected to the air outlet 130 .

[0047] The first connection part 340 is used to connect the heat dissipation cover 300 with the first heat dissipation fins 210 and the second heat dissipation fins 220. This connection ensures that the heat dissipation cover 300 is firmly mounted on the radiator while allowing effective heat transfer. The design of the first connection part 340 may adopt a variety of methods, such as snaps, screws, bonding or elastic fixation. It needs to match the shape and size of the heat dissipation fins so that it can be tightly connected. The second connection part 350 is used to connect the heat dissipation cover 300 to the air outlet 130. This ensures that the heat dissipation air flow can be smoothly discharged to the outside of the device through the air outlet 130 after flowing out of the heat dissipation fins. The design of the second connection part 350 can also be diversified, and may include slots, hooks, sealing strips and other forms to adapt to the shape and size of the air outlet 130.

[0048] Furthermore, the cross-sectional area of ​​the heat dissipation duct 310 at the second connection portion 350 is greater than the cross-sectional area of ​​the heat dissipation duct 310 at the first connection portion 340 .

[0049] The design of the heat dissipation system needs to take into account the characteristics of air flow. The air flow rate and flow rate at the air outlet 130 usually need to be greater than the air inlet 120 to ensure that the hot air can be discharged quickly and avoid heat accumulation.

[0050] Furthermore, two fans 140 are provided at the air outlet 130 .

[0051] By designing a larger second connection portion 350 , two fans 140 can be installed. The two fans 140 can work simultaneously, significantly increasing the air flow through the heat dissipation system, thereby improving the heat dissipation efficiency.

[0052] In some embodiments, the heat dissipation cover 300 further includes a bent portion 360 for connecting to the bottom of the inverter box 100 .

[0053] The bent portion 360 is a portion of the heat dissipation cover 300 that is designed to bend or fold to connect to the bottom of the inverter case 100 or other structures. The design of the bent portion 360 allows the heat dissipation cover 300 to be securely connected to the bottom of the inverter case 100, providing structural support and fixation.

[0054] In some embodiments, the heat dissipation cover 300 has fixing holes 370 for fixing to the inverter box 100 or the solar inverter assembly 200 .

[0055] The fixing holes 370 are usually located at the edge or specific positions of the heat dissipation cover 300, which are convenient for alignment with the fixing points of the inverter box 100 or the solar inverter assembly 200. The size of the fixing holes 370 needs to match the fixing screws or fasteners to ensure stability and security during fixing.
