[0015] (III) Beneficial Effects

[0016] This utility model provides a mounting structure for a micro inverter, which has the following advantages:

[0017] 1. The fixed structure of this micro inverter, through the integrated arrangement of ventilation slots, heat dissipation mesh, and air guide components, creates an air intake space on the back of the inverter body when the inverter body is installed. When the air guide fan is activated, it draws cool air from the air intake space into the ventilation slots, carrying away the heat from the back of the inverter body and expelling it from the air guide to the front. This ensures that hot air does not circulate back to the space on the back of the inverter body. Thus, the fixed structure actively and efficiently dissipates heat from the micro inverter, extending its service life and avoiding the need for frequent replacements due to inverter damage.

[0018] 2. This micro-inverter fixing structure, through the integrated design of pipe fitting connection components and adhesive connection components, allows for adaptable installation based on the micro-inverter's installation environment. When the micro-inverter needs to be fixed to a tubular structure, the compression ring is fitted onto the tubular structure and the B pressure bolt is tightened. When the micro-inverter needs to be fixed to a planar structure, the adhesive of the adhesive piece is used for bonding. This allows the micro-inverter to be installed in a way that is compatible with the installation scenario. Furthermore, the position of the micro-inverter can be fine-tuned using the pipe fitting sliding piece or the adhesive sliding piece, and then fixed by tightening the A or C pressure bolt. This improves the applicability of the micro-inverter fixing structure. Attached Figure Description

Through the combined arrangement of pipe connection component 7 and adhesive connection component 8, the applicability of the micro inverter mounting structure is improved;

[0026] The inverter body 1 has heat dissipation fins 9 on its side. There are two sets of heat dissipation fins 9, which are symmetrically distributed on both sides of the inverter body 1. The heat dissipation efficiency of the inverter body 1 is improved by setting the heat dissipation fins 9.

[0027] Mounting slots 10 are provided on both sides of the mounting plate 2. There are eight mounting slots 10 in total. The eight mounting slots 10 are evenly distributed on both sides of the mounting plate 2. The mounting slots 10 enable the micro inverter to be extended and fixed using anchor bolts.

[0028] There are four ventilation and heat dissipation slots 3 and four heat dissipation mesh 4. The four ventilation and heat dissipation slots 3 and heat dissipation mesh 4 are evenly distributed in a rectangular array on the surface of the mounting plate 2. The heat dissipation mesh 4 is made of stainless steel. The setting of the stainless steel heat dissipation mesh 4 increases the heat dissipation area of ​​the micro inverter. At the same time, the sturdy stainless steel heat dissipation mesh 4 can ensure that the A pressure bolt 11 or the C pressure bolt 14 can be pressed and fixed.

[0029] The sliding plate 701 of the pipe fitting is threaded with a pressure bolt 11 (A), and the compression ring 703 is threaded with a pressure bolt 12 (B). The pressure bolt 11 (A) is used to fix the sliding plate 701 of the pipe fitting by using the pressure.

[0032] The inverter body 1 is model CP-250. The above parameters and model can be selected according to the actual situation.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When the inverter body 1 is installed, the ventilation and heat dissipation slot 3 and the heat dissipation mesh 4 form an air intake space on the back of the inverter body 1. When the guide fan 501 is turned on, the guide fan 501 draws the cool air from the air intake space into the ventilation and heat dissipation slot 3, and carries the heat from the back of the inverter body 1 out through the air duct 502 to the front, and ensures that the hot air will not circulate to the space on the back of the inverter body 1, thereby using the fixed structure to actively and efficiently dissipate heat from the micro inverter.

[0035] The second step: Depending on the installation environment of the microinverter, when the microinverter needs to be fixed on a tubular structure, the compression ring 703 is fitted onto the tubular structure, and the B pressure bolt 12 is tightened. When the microinverter needs to be fixed on a planar structure, the adhesive of the adhesive piece 803 is used for adhesion, allowing the microinverter to be installed in an adaptable manner according to the installation scenario. Simultaneously, the position of the microinverter can be fine-tuned using the tubular sliding piece 701 or the adhesive sliding piece 801, and then the A pressure bolt 11 or C pressure bolt 14 is tightened for fixation.
