[0002] An inverter is a converter that converts direct current electrical energy (battery, storage battery) into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated alternating current (generally 220V, 50Hz sine wave). It consists of an inverter bridge, control logic, and a filter circuit, and is widely applicable to household appliances and production equipment. According to different application scenarios, the sizes of the inverters used are different, and micro-inverters have emerged and are used in medium and small-sized equipment. They have the advantages of being small and beautiful in size, can be directly installed on components or brackets, and are light in weight. Due to the continuous introduction of high-power components used in conjunction with them, the output power of micro photovoltaic inverters is getting larger.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a highly efficient heat dissipation type micro-inverter, including an inverter 1, a heat dissipation mechanism 2 is arranged at one end of the inverter 1, and a reinforcement mechanism 3 is arranged at one end of the inverter 1;

[0021] The heat dissipation mechanism 2 includes a water tank 201, a water injection pipe 202, a water pump 203, a water extraction pipe 204, a drain pipe 205, a heat dissipation water pipe 206, a partition plate 207, heat absorption fins 208, a heat dissipation fan 209 and a protection plate 210. One side surface of the inverter 1 is connected to the water tank 201. One end of the water tank 201 is provided with the water injection pipe 202. One side surface of the water tank 201 is fixedly installed with the water pump 203. One end of the water pump 203 is provided with the water extraction pipe 204. One end of the water tank 201 is provided with the drain pipe 205. One end of the drain pipe 205 is fixedly connected to the heat dissipation water pipe 206. A partition plate 207 is arranged inside the water tank 201. The heat absorption fins 208 are installed at the upper end of the partition plate 207. The heat dissipation fan 209 is installed on one side surface of the water tank 201. The protection plate 210 is fixedly installed on one side surface of the inverter 1. Through the settings of the water tank 201, the water injection pipe 202, the water pump 203, the water extraction pipe 204, the drain pipe 205, the heat dissipation water pipe 206, the partition plate 207, the heat absorption fins 208, the heat dissipation fan 209 and the protection plate 210, before dissipating heat from the inverter 1, first inject an appropriate amount of cold water into the water tank 201 through the water injection pipe 202. When the inverter 1 is working, the water pump 203 extracts the water in the water tank 201 through the water extraction pipe 204 and discharges the water into the heat dissipation water pipe 206 through the drain pipe 205. When the cold water flows in the heat dissipation water pipe 206, it can absorb the heat of the inverter 1. The water flow that has absorbed the heat flows back into the water tank 201 and contacts the heat absorption fins 208. The heat absorption fins 208 absorb its heat. At this time, the heat dissipation fan 209 rotates to discharge the heat on the heat absorption fins 208.

[0022] Further, a slot matching the size of the heat dissipation water pipe 206 is opened on one side of the protection plate 210. One side surface of the heat dissipation water pipe 206 is closely attached to one side surface of the inverter 1. Through the setting of the protection plate 210, the protection plate 210 can protect and fix the position of the heat dissipation water pipe 206 to prevent the heat dissipation water pipe 206 from being damaged.

[0023] Further, both ends of the heat dissipation water pipe 206 are respectively connected to the drain pipe 205 and the water tank 201. Through the setting of the heat dissipation water pipe 206, when the cold water flows in it, it can absorb the heat of the inverter 1, thereby enhancing the working safety of the inverter 1.

[0024] Furthermore, the reinforcement mechanism 3 includes a connector 301, a rubber pad 302, a first clamp 303, a connecting rod 304, a second clamp 305, a fixing groove 306, a bolt 307 and a nut 308. One end of the inverter 1 is provided with the connector 301, and the outer wall of the connector 301 is closely attached to the rubber pad 302. One side surface of the rubber pad 302 is adhesively connected to the first clamp 303. One end of the first clamp 303 is fixedly connected to the connecting rod 304. One end of the connecting rod 304 is connected to the second clamp 305. One end surface of the second clamp 305 is provided with the fixing groove 306. One end of the first clamp 303 is provided with the bolt 307, and one end of the bolt 307 is connected to the nut 308. Through the settings of the connector 301, the rubber pad 302, the first clamp 303, the connecting rod 304, the second clamp 305, the fixing groove 306, the bolt 307 and the nut 308, when connecting to the inverter 1, the first clamp 303 is installed at the connection part. The rubber pad 302 on the inner wall of the first clamp 303 wraps the connection part. Then the second clamp 305 is rotated. At this time, the second clamp 305 rotates around the connecting rod 304, so that the rubber pad 302 on the inner wall of the second clamp 305 wraps the other side of the connection part. Finally, the bolt 307 passes through the fixing groove 306 and is threadedly connected to the nut 308, so that water or dust cannot enter the connection part, completing the protection and reinforcement of the connection part.

[0025] Furthermore, the connecting rod 304 and the second clamp 305 are connected by a bearing. The connecting rod 304 and the second clamp 305 form a rotating structure. Through the setting of the connecting rod 304, the second clamp 305 can rotate around the connecting rod 304 at one end of the first clamp 303, and the second clamp 305 and the first clamp 303 can wrap the connection part, ensuring the safety of the connection part.

[0026] Furthermore, the fixing groove 306 is provided on one side surface of both the first clamp 303 and the second clamp 305, and the rubber pad 302 is adhesively connected to the inner walls of both the first clamp 303 and the second clamp 305. Through the setting of the rubber pad 302, the rubber pad 302 has good friction and sealing performance, can protect and reinforce the connection part, and will not cause damage to the connection part.

[0027] Furthermore, one end of the bolt 307 passes through the fixing groove 306 and is threadedly connected to the nut 308. Through the setting of the bolt 307, the bolt 307 passes through the fixing groove 306 provided on one side of the first clamp 303 and the second clamp 305 and is threadedly connected to the nut 308 to lock the first clamp 303 and the second clamp 305, so that the first clamp 303 and the second clamp 305 can protect and reinforce the connection part.

[0028] Working principle: First, inject an appropriate amount of cold water into the water tank 201 through the water injection pipe 202. When the inverter 1 is working, the water pump 203 pumps out the water in the water tank 201 through the water extraction pipe 204 and discharges the water into the heat dissipation water pipe 206 through the drain pipe 205. When the cold water flows in the heat dissipation water pipe 206, it can absorb the heat of the inverter 1. The water flow that has absorbed the heat flows back into the water tank 201 and contacts the heat absorption fin 208. The heat absorption fin 208 absorbs its heat. At this time, the cooling fan 209 rotates to discharge the heat on the heat absorption fin 208. When connecting to the inverter 1, install the first clamp 303 at the connection part. The rubber pad 302 on the inner wall of the first clamp 303 wraps the connection part. Then rotate the second clamp 305. At this time, the second clamp 305 rotates around the connecting rod 304 so that the rubber pad 302 on the inner wall of the second clamp 305 wraps the other side of the connection part. Finally, use the bolt 307 to pass through the fixing groove 306 and thread it with the nut 308, so that water or dust cannot enter the connection part, completing the protection and reinforcement of the connection part.
