Description

Technical Field

[0001] The invention relates to the technical field of solar inverters, and in particular to a cooling and heat dissipation structure for solar inverters. Background Art

[0002] In the current field of solar inverter technology, the design of cooling and heat dissipation structure is crucial to ensure the stable operation of the inverter and extend its service life. However, with the continuous improvement of solar inverter power and the diversification of working environment, the traditional heat dissipation structure has gradually shown its shortcomings, especially under high temperature, humid or changeable weather conditions. The heat inside the inverter is difficult to dissipate effectively and is easily affected by the external environment (such as rain), resulting in circuit short circuit and other faults.

[0003] The existing patent announcement number: CN109245561A discloses a cooling and heat dissipation structure for a solar inverter. The structure is equipped with components such as a circuit board, a heat collecting plate, heat dissipation fins and a heat dissipation fan inside the inverter. The heat on the circuit board is transferred to the heat collecting plate by heat conduction, and then the heat is dissipated by the cooperation of the heat dissipation fins and the fan. In addition, the structure is also equipped with a movable circular plate at the air outlet. The circular plate is driven by a cylinder to seal and shield on rainy days to prevent rainwater from entering the inverter. This design improves the heat dissipation efficiency and waterproof performance of the inverter to a certain extent.

[0004] However, although the structure has achieved certain results in heat dissipation and waterproofing, there are still some shortcomings: the layout of the cooling fins and the fan is not optimized, resulting in the heat dissipation efficiency not being optimal, and the position of the circular plate is not convenient for quickly discharging hot air, which in turn hinders the effective dissipation of heat, causing heat to accumulate inside the inverter, thereby reducing the service life of the inverter. Summary of the invention

[0049] (III) Beneficial effects

[0050] 1. The cooling and heat dissipation structure for the solar inverter, through the cooperation between the driving device and the heat dissipation device, the output end of the first servo motor undergoes a series of transmissions, and then synchronously drives the two heat dissipation fans to rotate, so as to facilitate the suction of external cold air into the interior of the inverter body, and at the same time, the dust and impurities in the air sucked into the inverter body are filtered through the filter net, and then the air flow is increased by using two heat dissipation fans, because two fans can generate a larger air volume than one fan, which helps to bring the heat on the heat dissipation fins to the external air faster, thereby improving the heat dissipation efficiency.

[0051] 2. The cooling and heat dissipation structure for the solar inverter has a wavy shape of the heat dissipation fins. The wavy design significantly increases the contact area between the fins and the air, so that more heat can be dissipated into the air through the fin surface. This design optimizes the heat conduction path and increases the heat dissipation area. At the same time, the wavy fin structure can improve the disturbance of the air between the fins, so that the air generates more eddies and turbulence when flowing through the fins, thereby enhancing the convective heat transfer effect and further improving the heat dissipation efficiency.

[0052] 3. The cooling and heat dissipation structure for the solar inverter can achieve a larger heat dissipation area in a limited space due to the setting of the heat dissipation fins, thereby making the volume of the entire radiator more compact, saving installation space, and thus improving the adaptability of the device.

[0053] 4. The cooling and heat dissipation structure for the solar inverter has heat dissipation grooves evenly opened on the front and rear sides of the heat dissipation fins, so that the heat dissipation fins further increase the contact area with the air in the heat dissipation grooves through the heat dissipation grooves, so that the heat on the fins can be dissipated more quickly through the rectangular air outlet, thereby further improving the heat dissipation efficiency.

[0054] 5. The cooling and heat dissipation structure for the solar inverter, due to the setting of the flat-top cone cover, enables the heat on the heat dissipation fins to be transferred to the external air of the inverter body through the rectangular air outlet more quickly, which helps to reduce the resistance in the air flow process, so that the heat can be transferred to the external environment more smoothly, thereby improving the heat dissipation effect.

[0055] 6. The cooling and heat dissipation structure for the solar inverter is provided with a moving device, so that the telescopic end of the electric telescopic rod moves to drive the baffle to slide vertically downward inside the rectangular groove, thereby shielding the rectangular air outlet to prevent rainwater from entering the inverter and causing a circuit short circuit. At the same time, the dust or impurities adhered to the outer surface of the dustproof net are scraped off by the inclined end of the baffle, thereby facilitating the cleaning of the dust adhered to the outer surface of the dustproof net, thereby improving the practicality of the device.

[0056] 7. The cooling and heat dissipation structure for the solar inverter, when used in normal weather, has the baffle located inside the rectangular groove so that the baffle is not arranged corresponding to the rectangular air outlet, thereby facilitating the rapid discharge of hot air, contributing to the rapid and effective dissipation of heat, avoiding heat accumulation inside the inverter, and thereby increasing the service life of the inverter.

[0057] 8. The cooling and heat dissipation structure for the solar inverter is provided with a cooling device, and the tap water inside the cooling box is cooled by a semiconductor refrigerator. The cooled water is transported to the inside of the heat exchange coil through the output end of the water pump. The cold air passing through the heat exchange coil and entering the inverter body is further cooled by the heat exchange coil, so that the heat dissipation of the heat dissipation fins can be better performed, thereby further increasing the heat dissipation efficiency of the heat dissipation fins.

[0058] 9. The cooling and heat dissipation structure for the solar inverter, due to the arrangement of the two brush plates, rotates the output end of the first servo motor to synchronously drive the brush plate to rotate, and then the dust on the outer surface of the filter is cleaned promptly and effectively by the brush on the brush plate, so that the device can quickly and effectively clean the dust on the filter, with a high degree of automation, further improving the service life of the inverter.

[0059] 10. The cooling and heat dissipation structure for the solar inverter cooperates with each other through the rectangular hole, the hexagonal nut, the fixing tube, the rectangular block, the screw, the clamping block and the clamping groove, so that the brush plate and the filter can be disassembled synchronously by unscrewing the hexagonal nut, thereby facilitating the replacement of the brush plate and the disassembly and cleaning of the filter, thereby improving the work efficiency of the synchronous disassembly of the filter and the brush plate.

By using two cooling fans 46 to increase the air flow, because two fans can generate a larger air volume than one fan, which helps to take away the heat on the cooling fins 21 faster and improve the heat dissipation efficiency.

[0111] Furthermore, the cooling device includes a cooling box 3, which is fixedly mounted on the upper surface of the sealed box cover 2 near one end of the circular air inlet 41, and tap water is provided inside the cooling box 3.

[0115] Among them, the end of the heat exchange coil 32 away from the cold water outlet pipe is fixedly connected to the water inlet pipe, and the end of the water inlet pipe away from the heat exchange coil 32 passes through the outer surface of the sealed box cover 2 and is fixedly connected to the top of the rear end of the cooling box 3, and the water inlet pipe is connected to the interior of the cooling box 3;

[0116] The heat exchange coil 32 is composed of two conical spiral coils, and the two conical spiral coils are fixedly connected and communicated with each other through a connecting pipe. The two conical spiral coils are respectively arranged corresponding to the two circular air inlets 41, and the semiconductor refrigerator 34 is electrically connected to the control panel.

[0117] Furthermore, by providing a cooling device, the tap water inside the cooling box 3 is cooled by the semiconductor refrigerator 34, and the cooled water is transported to the inside of the heat exchange coil 32 through the output end of the water pump 35, and then flows into the cooling box 3 from the other end of the heat exchange coil 32. In this process, the heat exchange coil 32 will further cool the cold air passing through it and entering the inverter body 1, so that it can better dissipate the heat to the heat sink fins 21, further increasing the heat dissipation efficiency of the heat sink fins 21.

[0118] Furthermore, each heat dissipation fin 21 has arc surfaces on both the front and rear sides of one end away from the rectangular air outlet 4, and heat dissipation grooves 27 are evenly opened on the front and rear sides of each heat dissipation fin 21, and the heat dissipation fin 21 is made of copper.

[0119] Furthermore, due to the arrangement of the heat dissipation fins 21, the heat dissipation fins 21 can achieve a larger heat dissipation area within a limited space, thereby making the volume of the entire radiator more compact, saving installation space, and further improving the adaptability of the device.

[0120] Furthermore, since heat dissipation grooves 27 are evenly opened on the front and rear sides of the heat dissipation fins 21, the heat dissipation grooves 27 further increase the contact area between the heat dissipation fins 21 and the air in the heat dissipation grooves 27, so that the heat on the heat dissipation fins 21 can be dissipated more quickly through the rectangular air outlet 4, thereby further improving the heat dissipation efficiency.

[0121] Furthermore, the moving device includes an electric telescopic rod 7, a mounting block 28 is fixedly mounted at the bottom of the fixed end of the electric telescopic rod 7, and the mounting block 28 is fixedly mounted at the longitudinal middle position on the right side of the top of the inverter body 1 by the same screws;

[0124] Furthermore, by providing a moving device, the movement of the telescopic end of the electric telescopic rod 7 drives the baffle 30 to slide vertically downward inside the rectangular groove 29, thereby shielding the rectangular air outlet 4 to prevent rainwater from entering the inverter and causing a circuit short circuit. At the same time, the dust or impurities adhered to the outer surface of the dustproof net 5 are scraped off by the inclined end of the baffle 30, thereby facilitating the cleaning of the dust adhered to the outer surface of the dustproof net 5, thereby improving the practicability of the device.

[0125] Furthermore, since the baffle 30 is located inside the rectangular groove 29 when used in normal weather, the baffle 30 is not arranged corresponding to the rectangular air outlet 4, which facilitates the rapid discharge of hot air, helps to quickly and effectively dissipate heat, avoids heat accumulation inside the inverter, and thus increases the service life of the inverter.

[0126] Furthermore, a rain shield 6 is fixedly installed on the outer surface of the inverter body 1 at a position corresponding to the rectangular air outlet 4, and the rain shield 6 is arranged just above the rectangular air outlet 4.

[0127] A through hole 31 matching with the mounting block 28 is provided on the sealing box cover 2 at a position corresponding to the mounting block 28 .

[0128] Furthermore, the rotating device includes a fixing plate 37, the fixing plate 37 is fixedly mounted on the front end of the left side of the outer surface of the inverter body 1, and a second servo motor 38 is fixedly mounted on the upper surface of the fixing plate 37;

[0129] Among them, ear plates 11 are fixedly installed on the front and rear sides of the left top of the outer surface of the inverter body 1, and a first rotating shaft 40 is rotatably installed between the two ear plates 11. The front end of the first rotating shaft 40 is fixedly connected to the output end of the second servo motor 38;

[0130] An L-shaped rotating rod 54 is sleeved and fixedly installed on the outer surface of the first rotating shaft 40, and a convex sealing plate 10 is fixedly installed on the ends of the two L-shaped rotating rods 54 away from the first rotating shaft 40 by screws, and a sealing ring is provided on the inner wall of the two convex sealing plates 10;

[0131] The two convex sealing plates 10 are respectively arranged to be tightly fitted with the two annular protective covers 12 at one end away from the inverter body 1 , and the second servo motor 38 is electrically connected to the control panel.

[0132] Furthermore, on rainy days, the output end of the second servo motor 38 rotates to drive the first rotating shaft 40 to rotate, thereby synchronously driving the two L-shaped rotating rods 54 to rotate, and then synchronously driving the two convex sealing plates 10 to seal the two annular protective covers 12 respectively, thereby preventing rainwater from entering the inverter body 1 through the two annular protective covers 12, thereby improving the sealing of the interior of the inverter body 1.

[0133] Working principle: When the cooling and heat dissipation structure for the solar inverter is used, the inverter body 1 is fixedly mounted on the solar bracket through the mounting holes on the mounting plate 9, and the power is turned on. The heat of the circuit board 16 in the inverter is guided to the heat collecting plate 18 through the heat conducting strip 17, and then the heat is dissipated through the heat dissipation fins 21. The output end of the first servo motor 8 rotates to drive the second rotating shaft 43 to rotate, and then synchronously drives the two first bevel gears 44 to rotate, and then the two first bevel gears 44 respectively drive the second bevel gears 49 meshing with them to rotate, and then synchronously drive the two third rotating shafts 48 to rotate, and then synchronously drive the two cooling fans 46 to rotate, so as to facilitate the suction of external cold air into the interior of the inverter body 1. By using two cooling fans 46, the air flow is increased, because two fans can generate a larger air volume than one fan, which helps to take away the heat on the heat dissipation fins 21 faster, thereby improving the heat dissipation efficiency;

[0134] Furthermore, since the shape of the heat dissipation fins 21 is wavy, the wavy design significantly increases the contact area between the fins and the air, so that more heat can be dissipated into the air through the fin surface. This design optimizes the heat conduction path and increases the heat dissipation area. At the same time, the wavy fin structure can improve the disturbance degree of the air between the fins, so that the air generates more eddies and turbulence when flowing through the fins, thereby enhancing the convective heat transfer effect and further improving the heat dissipation efficiency.

[0135] Furthermore, since the heat dissipation grooves 27 are evenly provided on the front and rear sides of the heat dissipation fins 21, the heat dissipation fins 21 further increase the contact area with the air in the heat dissipation grooves 27 through the heat dissipation grooves 27, so that the heat on the heat dissipation fins 21 can be dissipated more quickly through the rectangular air outlet 4, thereby further improving the heat dissipation efficiency;

[0136] Furthermore, due to the arrangement of the flat-top cone cover 20, the heat on the heat dissipation fins 21 can be transferred to the external air of the inverter body 1 through the rectangular air outlet 4 more quickly, which helps to reduce the resistance in the air flow process, so that the heat can be transferred to the external environment more smoothly, thereby improving the heat dissipation effect;

[0137] Furthermore, the movement of the telescopic end of the electric telescopic rod 7 drives the baffle plate 30 to slide vertically downward inside the rectangular groove 29, thereby shielding the rectangular air outlet 4, preventing rainwater from entering the inverter and causing a circuit short circuit. At the same time, the dust or impurities adhering to the outer surface of the dustproof net 5 are scraped off by the inclined end of the baffle plate 30, thereby facilitating the cleaning of the dust adhering to the outer surface of the dustproof net 5, thereby improving the practicality of the device;

[0138] Furthermore, since the baffle 30 is located inside the rectangular groove 29 when used in normal weather, the baffle 30 is not arranged corresponding to the rectangular air outlet 4, so that the hot air can be quickly discharged, which helps to quickly and effectively dissipate the heat, avoids the accumulation of heat inside the inverter, and thus improves the service life of the inverter;

[0139] Furthermore, the tap water inside the cooling box 3 is cooled by the semiconductor refrigerator 34, and the cooled water is transported to the inside of the heat exchange coil 32 through the output end of the water pump 35. The cold air passing through the heat exchange coil 32 and entering the inverter body 1 is further cooled by the heat exchange coil 32, so that the cold air can be better cooled by the heat dissipation fins 21, and the heat dissipation efficiency of the heat dissipation fins 21 is further increased.

[0140] Furthermore, due to the arrangement of the two brush plates 14, the brush plates 14 are driven to rotate synchronously by the rotation of the output end of the first servo motor 8, and the dust on the outer surface of the filter 13 is promptly and effectively cleaned by the brush on the brush plate 14, so that the device can quickly and effectively clean the dust on the filter 13, with a high degree of automation, and further improve the service life of the inverter;

[0141] Furthermore, through the cooperation between the rectangular hole 39, the hexagonal nut 47, the fixing tube 53, the rectangular block 50, the screw 51, the block 52 and the slot 42, it is convenient to simultaneously disassemble the brush plate 14 and the filter screen 13 by unscrewing the hexagonal nut 47, thereby facilitating the replacement of the brush plate 14 and the disassembly and cleaning of the filter screen 13, thereby improving the work efficiency of the simultaneous disassembly of the filter screen 13 and the brush plate 14.
