Description
A photovoltaic inverter heat dissipation device with intelligent temperature control function Technical Field
[0001] This utility model relates to the technical field of inverter heat dissipation devices, and in particular to a photovoltaic inverter heat dissipation device with intelligent temperature control function. Background Technology
[0002] Photovoltaic inverters are the core equipment in photovoltaic power generation systems. Their main function is to convert the direct current (DC) generated by photovoltaic modules into alternating current (AC) to meet the power demand of AC loads or to be connected to the grid. As the "heart" of the photovoltaic system, the performance of the inverter directly affects power generation efficiency, system stability, and return on investment. Currently, inverters are often equipped with cooling devices such as fans to dissipate heat from their internal components. However, most current cooling fans are installed at a fixed angle, which cannot be adjusted to different angles according to usage requirements, resulting in limitations in the heat dissipation angle. Moreover, existing cooling devices are used with dust filters to prevent dust from entering, but dust filters are mostly fixed with screws or interlaced. Screw-fixed filters are cumbersome to disassemble, and interlaced filters are prone to loosening and falling off. Therefore, we have launched a photovoltaic inverter cooling device with intelligent temperature control function. Summary of the Invention
[0003] The main purpose of this invention is to provide a heat dissipation device for a photovoltaic inverter with intelligent temperature control function, which can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A photovoltaic inverter heat dissipation device with intelligent temperature control function includes an inverter body. A control panel and several operation buttons are installed and connected to the front end of the inverter body. Two mounting legs are fixedly connected to the rear left and rear right ends of the inverter body. An outer shell is fixedly connected to the middle right end of the inverter body. The outer shell has an internal hollow structure and is internally connected to the inverter body. Three heat dissipation mechanisms are movably connected inside the outer shell. A dustproof device is movably connected to the right rear end of the outer shell.
[0006] Preferably, the heat dissipation mechanism includes a heat dissipation fan, a connecting shaft is fixedly connected to the rear part of the outer surface of the heat dissipation fan, and a limiting shaft is fixedly connected to the front part of the outer surface of the heat dissipation fan. The limiting shaft has an "L" shaped structure, and a threaded hole is opened on the left side of the front end of the limiting shaft. A limiting bolt is threadedly connected in the threaded hole.
[0007] Preferably, a temperature sensor is installed and connected to the left side of the inner wall of the outer casing, a slot is opened on the right side of the rear end of the outer casing, three connection holes are opened at the front end of the outer casing, all three connection holes penetrate and extend to the rear end of the outer casing, and three high limit holes, middle limit holes and low limit holes are opened at the front end of the outer casing.
[0008] Preferably, the three connecting holes, the three low-limit holes, the three middle-limit holes, and the three high-limit holes are divided into three groups.
[0009] Preferably, both the connecting shaft and the limiting shaft are movably connected to the connecting hole via bearings, and the cooling fan is located inside the outer casing.
[0010] Preferably, the dustproof device includes a frame, a handle is fixedly connected to the rear end of the frame, a dustproof net is installed and connected inside the frame, clamps are fixedly connected to the upper and lower ends of the frame, and a locking block is fixedly connected to the end of each clamp away from the frame.
[0011] Preferably, the frame is movably connected to the slot, and the two clamps are located at the upper and lower parts of the outer shell, respectively.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, by setting up a heat dissipation mechanism, the connecting shaft and the limiting shaft installed on the outer surface of the heat dissipation fan are connected to the outer shell through bearings, so that the heat dissipation fan can freely adjust its angle within the outer shell. By moving the limiting shaft, since the outer shell has a low limiting hole, a middle limiting hole and a middle limiting hole with the limiting shaft as the center, the limiting bolt is threaded to the limiting shaft, and then the limiting bolt is inserted into the low limiting hole, the middle limiting hole or the middle limiting hole, so that the heat dissipation fan at three angles can be limited, thereby improving heat dissipation efficiency and flexibility.
[0014] 2. In this utility model, by setting a dustproof device, after the frame and the outer shell are interlocked, the two clamps are located at the upper and lower ends of the outer shell. After the frame is fully inserted, the locking blocks at the ends of the two clamps will hold the outer shell, limiting the frame and the dustproof net inside it, so that the frame can be quickly installed and disassembled, improving convenience.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Please refer to Figures 1-4. This utility model provides a technical solution:
[0024] A photovoltaic inverter heat dissipation device with intelligent temperature control function includes an inverter body 1. A control panel 7 and several operation buttons 6 are installed and connected to the front end of the inverter body 1. Two mounting legs 2 are fixedly connected to the rear left and rear right ends of the inverter body 1. An outer shell 3 is fixedly connected to the middle right end of the inverter body 1. The outer shell 3 has an internal hollow structure and is internally connected to the inverter body 1. Three heat dissipation mechanisms 5 are movably connected inside the outer shell 3. A dustproof device 4 is movably connected to the rear right end of the outer shell 3.
[0025] In this embodiment, the heat dissipation mechanism 5 includes a heat dissipation fan 51. A connecting shaft 52 is fixedly connected to the rear part of the outer surface of the heat dissipation fan 51. A limiting shaft 53 is fixedly connected to the front part of the outer surface of the heat dissipation fan 51. The limiting shaft 53 has an "L" shaped structure. A threaded hole 54 is opened on the left side of the front end of the limiting shaft 53. A limiting bolt 55 is connected to the threaded hole 54. A temperature sensor 36 is installed and connected to the left side of the inner wall of the outer shell 3. A slot 33 is opened on the right side of the rear end of the outer shell 3. Three connecting holes 32 are opened at the front end of the outer shell 3. All three connecting holes 32 penetrate and extend to the rear end of the outer shell 3. Three high limiting holes 34, middle limiting holes 35 and low limiting holes 31 are opened at the front end of the outer shell 3. The three connecting holes 32, three low limiting holes 31, three middle limiting holes 35 and three high limiting holes 34 are divided into three groups. The connecting shaft 52 and the limiting shaft 53 are movably connected to the connecting holes 32 through bearings. The heat dissipation fan 51 is located inside the outer shell 3.
[0026] By using the above method: by moving the limiting shaft 53, the limiting bolt 55 can be inserted into the low limiting hole 31, the middle limiting hole 35 or the middle limiting hole 35 as needed, and the cooling fan 51 after the angle is adjusted can be limited.
[0027] In this embodiment, the dustproof device 4 includes a frame 41, a handle 42 is fixedly connected to the rear end of the frame 41, a dustproof net 43 is installed and connected inside the frame 41, and clamps 45 are fixedly connected to the upper and lower ends of the frame 41. A locking block 44 is fixedly connected to the end of the two clamps 45 away from the frame 41. The frame 41 is movably connected to the slot 33, and the two clamps 45 are located at the upper and lower parts of the outer shell 3, respectively.
[0028] The above solution involves inserting the frame 41 into the outer shell 3. At this time, the two clamping plates 45 are slightly deformed and open, and are located at the upper and lower ends of the outer shell 3 respectively. After the frame 41 is fully inserted, the locking blocks 44 at the ends of the two clamping plates 45 will hold the outer shell 3, thereby realizing the quick installation and disassembly of the frame 41 and the dustproof net 43, which improves convenience.
[0029] It should be noted that this utility model describes a photovoltaic inverter heat dissipation device with intelligent temperature control function. When the angle of the cooling fan 51 needs to be adjusted, by moving the limiting shaft 53, since the outer casing 3 has a low limiting hole 31, a middle limiting hole 35 and a middle limiting hole 35 centered on the limiting shaft 53, by threading the limiting bolt 55 to the limiting shaft 53, and then inserting the limiting bolt 55 into the low limiting hole 31, the middle limiting hole 35 or the middle limiting hole 35, the cooling fan 51 at three angles can be limited, improving heat dissipation efficiency and flexibility. By operating the other two heat dissipation mechanisms 5 in the same way, heat dissipation at different angles can be achieved. After installation, the temperature sensor 36 detects the internal temperature of the inverter body 1. When the temperature is too high and temperature control is required, the temperature sensor 36 sends an electrical signal to the control panel 7, causing the control panel 7 to start the three cooling fans 51 to dissipate heat. When the frame 41 and dust filter 43 need to be installed, the frame 41 is inserted and connected to the outer shell 3. At this time, the two clamping plates 45 are slightly deformed and opened, respectively located at the upper and lower ends of the outer shell 3. After the frame 41 is fully inserted, the locking blocks 44 at the ends of the two clamping plates 45 will hold the outer shell 3, limiting the frame 41 and the dust filter 43 inside it, so that the frame 41 can be installed quickly, improving convenience.
