Description

Technical Field

[0001] This invention relates to the field of photovoltaic inverter technology, specifically to a photovoltaic inverter metal casing and its molding structure with an anti-corrosion coating. Background Technology

[0002] As a key component of photovoltaic power generation systems, the stability and reliability of photovoltaic inverters directly affect the power generation efficiency and lifespan of the entire system. In coastal areas, salt spray environments can easily cause corrosion of inverter equipment, affecting power generation efficiency and equipment lifespan. In high-altitude areas, the dry climate and strong ultraviolet radiation can also lead to corrosion of inverter equipment. Therefore, it is necessary to improve the corrosion resistance of inverters to adapt to different operating environments.

[0003] Traditional thin-plate molded chassis shells are painted on the outside for corrosion protection. However, when subjected to external forces, the joints are prone to cracking or developing fissures. After being bumped or knocked, the exposed interior is easily corroded and rusted. Therefore, this invention provides a metal shell and molding structure for photovoltaic inverters with an anti-corrosion coating. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a photovoltaic inverter metal shell and molding structure with anti-corrosion coating, including an inverter body, a support frame fixedly connected to the inner wall of the inverter body, a distribution panel fixedly connected to the middle of the inner wall of the support frame by bolts, stable mounting brackets fixedly connected to the four corners of the outer surface of the inverter body, and a protective shell fixedly connected to the bottom of the inner wall of the inverter body.

[0006] The inverter body includes a main shell, the outer surface of which is provided with an anti-corrosion coating, and the outer surface of which is provided with a paint coating.

[0007] Preferably, the stable mounting bracket includes a fixed bracket, the bottom of which is fixedly connected to several damping rods, the outer surface of which is fitted with springs, the bottom of which is fixedly connected to a connecting plate connected to the inverter body, and the front of which is provided with several mounting holes.

[0008] Preferably, the inner wall of the protective shell is fixedly connected to an installation frame, and the inner wall of the installation frame is fixedly connected to a cooling fan.

[0009] Preferably, the upper surface of the protective shell is provided with a heat dissipation vent, which is adapted to a cooling fan.

[0010] Preferably, the inverter body has an exhaust port at the bottom, and the exhaust port is adapted to a cooling fan.

[0011] Preferably, heat exchange ports are provided on both sides of the inner wall of the inverter body, and the heat exchange ports are adapted to the exhaust ports.

[0012] Preferably, protective strips are fixedly connected to both sides of the inverter body, and a door panel is rotatably connected to the front end of the inverter body via a hinge.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The photovoltaic inverter metal casing and molding structure with anti-corrosion coating described in this invention can isolate outdoor corrosive factors such as rainwater, salt spray, and ultraviolet rays by setting a double layer of protection on the outside of the main casing with anti-corrosion coating and paint coating, so as to avoid rusting or aging of the metal casing. The protective strips on both sides can buffer the impact of external forces such as collision and squeezing, reduce damage to the main structure, and further ensure the integrity of the device for long-term use.

[0015] 2. The photovoltaic inverter metal casing and molding structure with anti-corrosion coating described in this invention, through the damping rod and spring in the stable mounting bracket to form a shock absorption structure, can absorb interference such as outdoor wind force and ground vibration, and prevent internal precision components such as the distribution panel from loosening or being damaged due to vibration. The cooling fan, heat dissipation port, exhaust port and heat exchange port form a complete airflow circulation system, which can quickly remove the heat generated by the operation of internal electronic components, and avoid performance degradation or component burnout due to high temperature.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown, the photovoltaic inverter metal shell and molding structure with anti-corrosion coating of the present invention includes an inverter body 1, a support frame 2 fixedly connected to the inner wall of the inverter body 1, a distribution panel 3 fixedly connected to the middle of the inner wall of the support frame 2 by bolts, stable mounting brackets 4 fixedly connected to the four corners of the outer surface of the inverter body 1, and a protective shell 5 fixedly connected to the bottom of the inner wall of the inverter body 1.

[0026] The inverter body 1 includes a main shell 103. The outer surface of the main shell 103 is provided with an anti-corrosion coating 102, and the outer surface of the anti-corrosion coating 102 is provided with a paint coating 101. The inner wall of the inverter body 1 is fixed to the distribution panel 3 by a support frame 2, providing a stable installation position for the distribution panel and ensuring its normal operation. The stable mounting brackets 4 at the four corners of the outer surface of the inverter body 1 are used to fix the inverter in a specific position to ensure its installation stability. The protective shell 5 at the bottom of the inner wall of the inverter body 1 can protect some internal components, such as preventing dust and foreign objects from entering and affecting the operation of the components. The anti-corrosion coating 102 on the outer surface of the main shell 103 can prevent the metal shell from being corroded by the external environment, such as preventing rainwater and salt spray from corroding the metal and extending the service life of the shell. The paint coating 101 can further protect the anti-corrosion coating and also serve an aesthetic purpose.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the stable mounting bracket 4 includes a fixed bracket 401. Several damping rods 402 are fixedly connected to the bottom of the fixed bracket 401. Springs 403 are sleeved on the outer surface of the damping rods 402. A connecting plate 404 connected to the inverter body 1 is fixedly connected to the bottom of the damping rods 402. Several mounting holes 405 are opened on the front of the fixed bracket 401. The damping rods 402 and springs 403 in the stable mounting bracket 4 constitute a shock absorption structure. When the inverter is subjected to vibration or impact, the damping rods can absorb some energy, and the springs can buffer the vibration through elastic deformation, reducing the impact of vibration on the internal components of the inverter and ensuring the normal operation of the inverter. The mounting holes 405 on the fixed bracket 401 are used to connect with external mounting components to realize the fixed installation of the inverter.

[0028] like Figures 1 to 3 As shown, a mounting frame 6 is fixedly connected to the inner wall of the protective shell 5, and a cooling fan 7 is fixedly connected to the inner wall of the mounting frame 6. The cooling fan 7 inside the protective shell 5 is fixed by the mounting frame 6. When the cooling fan is working, it can extract the heat generated inside the inverter and discharge it through the heat dissipation port 8, thereby reducing the temperature inside the inverter, ensuring that the internal electronic components work within a suitable temperature range, and improving the performance and stability of the inverter.

[0029] like Figures 1 to 3 As shown, the upper surface of the protective shell 5 is provided with a heat dissipation vent 8, which is adapted to the cooling fan 7. When the cooling fan 7 is running, air enters the protective shell 5 through the heat dissipation vent 8 and is then discharged through the cooling fan, forming an airflow channel, which effectively carries the heat out of the inverter body and realizes the heat dissipation function.

[0030] like Figures 1 to 3 As shown, an exhaust port 9 is provided at the bottom of the inverter body 1. The exhaust port 9 is adapted to the cooling fan 7. The exhaust port 9 at the bottom of the inverter body 1 is adapted to the cooling fan 7. The cooling fan 7 exhausts the hot air inside the protective shell 5 to the outside of the inverter body through the exhaust port 9, promotes air circulation inside the inverter, and enhances the heat dissipation effect.

[0031] like Figures 1 to 3 As shown, heat exchange ports 10 are provided on both sides of the inner wall of the inverter body 1. The heat exchange ports 10 are adapted to the exhaust ports 9. When the cooling fan 7 is working, the hot air inside the inverter flows to the exhaust port 9 through the heat exchange ports 10 and is then discharged. At the same time, the cold air outside can enter the inverter through the heat exchange ports 10 to achieve heat exchange and further improve the heat dissipation efficiency.

[0032] like Figures 1 to 3As shown, protective strips 11 are fixedly connected to both sides of the inverter body 1. A door panel 12 is rotatably connected to the front end of the inverter body 1 via a hinge. The protective strips 11 on both sides of the inverter body 1 can buffer and protect the inverter when it is hit or squeezed, preventing damage to the main body shell. The door panel 12 at the front end is rotatably connected via a hinge, making it convenient for staff to open the door panel to install, debug, repair and inspect the internal components of the inverter.

[0033] During operation, the device is fixed by the four corner mounting brackets 4. The damping rods 402 and springs 403 in the brackets can buffer external vibrations or impacts, preventing internal components such as the distribution panel 3 from being damaged by vibration, and providing a stable environment for overall operation. The main body shell 103 of the inverter body 1 is provided with an anti-corrosion coating 102 and a paint coating 101 in sequence. The anti-corrosion coating isolates corrosive substances such as rainwater and salt spray, while the paint coating further protects the anti-corrosion layer and improves the appearance, extending the outdoor service life of the device.

[0034] The cooling fan 7 inside the protective shell 5 starts, drawing in external cold air through the heat dissipation vent 8 on the upper surface. The cold air flows through the inside of the protective shell, absorbs the heat generated by the inverter operation, and is then pushed by the cooling fan to the exhaust port 9 at the bottom of the inverter body, and finally discharged outside the device. At the same time, the heat exchange vents 10 on both sides of the inner wall of the inverter body form an airflow channel with the exhaust port. The internal hot air flows to the exhaust port through the heat exchange vents, and the external cold air can also enter through the heat exchange vents to accelerate heat exchange and ensure that the internal electronic components are in a suitable temperature range.

[0035] The protective strips 11 on both sides of the inverter body can act as a buffer in case of collision or compression, preventing deformation of the main shell or damage to internal components.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
