Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically to a heat dissipation structure for an inverter. Background Technology

[0002] An inverter converts direct current (DC) energy (from batteries or storage batteries) into alternating current (typically 220V, 50Hz sine wave). It consists of an inverter bridge, control logic, and filter circuits, and is widely used in air conditioners, home theaters, electric grinders, power tools, refrigerators, video recorders, massagers, fans, lighting, etc. However, existing inverters contain a variety of electronic components, which generate heat during operation. Excessive heat can cause the internal temperature of the inverter to rise and easily damage the electronic components. Therefore, rapid heat dissipation is required to balance the internal temperature of the inverter.

[0003] According to Chinese Patent Publication No. CN221328806U, an inverter heat dissipation structure is disclosed. This structure simplifies the overall mounting box by facilitating installation and connection of the mounting structure. The control plate facilitates the installation of control knobs and the ventilation fan structure. The mounting base facilitates the installation and fixing of the working device. The switch and socket plate facilitates the installation of sockets and switches. Simultaneously, the ventilation fan structure allows for opposing airflow for heat dissipation. The ventilation fan structure rapidly dissipates and removes heat from the internal space, ensuring a stable internal temperature. A small motor drives the fan blades to rotate in both directions. The device rotates to allow for exhaust and air supply. The spiral protective cover can be rotated and removed for easy dust cleaning. The device uses a ventilated plate structure and a protective plate to transfer and dissipate heat from the internal and side areas. Heat dissipation is achieved through heat dissipation strips and then discharged through vents. The hollow plate is equipped with heat-absorbing filler to accelerate heat absorption and protect the sides of the device. The device can be quickly opened by a hinged inspection cover for easy maintenance and replacement of internal components. The split top plate can be flipped open by rotating a rod. When closed, the fixed connector is inserted into the hole of the docking block to lock it in place.

[0004] However, in this technical solution, when the ventilation fan structure fails, it is difficult for personnel to disassemble and replace it in a timely manner. The inverter body needs to be shut down first before the ventilation fan structure can be maintained and replaced, which affects the normal operating efficiency of the inverter body. Therefore, we propose an inverter heat dissipation structure. Utility Model Content

The T-shaped sliding plate and the T-shaped sliding groove are slidably connected. By setting the T-shaped sliding plate and the T-shaped sliding groove, the first fixed frame and the second fixed frame can be limited, so that the first fixed frame and the second fixed frame can be fixedly slid on one side of the inverter body.

By setting the limit rod, the movable block and the spring can be limited, ensuring the stability of the movable block when moving and the spring when compressed.

[0010] Preferably, the second fixed frame is provided with a storage shell on the outside. The storage shell is fixedly installed on one side of the inverter body. By providing the storage shell, the cooling fan 2 in the second fixed frame can be protected to a certain extent.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1:

[0026] A preferred embodiment of the inverter heat dissipation structure provided by this utility model is, for example... Figures 1 to 6 As shown: An inverter heat dissipation structure includes an inverter body 1, a heat dissipation port 2 on one side of the inverter body 1, and a vent 3 on the other side of the inverter body 1. A fixing frame 5 is provided on one side of the heat dissipation port 2, and a fixing frame 7 is provided below the fixing frame 5. The fixing frame 5 and the fixing frame 7 are slidably connected to one side of the inverter body 1. A connecting component is provided between the fixing frame 5 and the fixing frame 7. A cooling fan 6 and a cooling fan 8 are respectively fixedly installed inside the fixing frame 5 and the fixing frame 7. A retaining plate 15 is slidably connected to one side of the inverter body 1. A retaining groove 16 is provided on the outer wall of the fixing frame 5 and the fixing frame 7, and the retaining plate 15 is inserted into the retaining groove 16.

[0027] Specifically, in the above technical solution, when the inverter heat dissipation structure is in use, the cooling fan 6 in the fixed frame 5 is activated, allowing the cooling fan to expel heat from the inside of the inverter body 1 through the heat dissipation port 2, thereby achieving heat dissipation of the inverter body 1. When the cooling fan 6 in the fixed frame 5 malfunctions, the locking plate 15 can be pulled outwards directly, causing the locking plate 15 to drive the moving block 12 to compress the spring 14, causing the locking plate 15 to disengage from the locking slot 16 on the fixed frame 5, so that the locking plate 15 no longer limits the fixed frame 5. At this time, the fixed frame 5 can be pulled upwards directly, so that the fixed frame 5 and the cooling fan 6 are not on the side of the heat dissipation port 2. The fixed frame 5, through the connecting component, drives the fixed frame 7 upwards, so that the fixed frame 7 and the cooling fan 8 are on the side of the heat dissipation port 2. Then the locking plate 15 is released. When the moving block 12 is activated by the reset force of the spring 14, it drives the card plate 15 to insert into the slot 16 on the fixed frame 7, thereby limiting and fixing the fixed frame 7. Then, the cooling fan 8 in the fixed frame 7 is directly started, so that the cooling fan 8 continuously dissipates heat from the inverter body 1. Through the above structure, a backup cooling fan is designed. When one set of cooling fans fails, it can be replaced with another set of cooling fans in time, ensuring the normal heat dissipation of the inverter body 1 during use, improving the reliability and stability of the heat dissipation structure, and solving the problem in the existing technical solution that when the ventilation fan structure fails, it is difficult for personnel to disassemble and replace it in time. The inverter body 1 must be stopped first before the ventilation fan structure can be maintained and replaced, which affects the normal operating efficiency of the inverter body 1.

[0028] Furthermore, T-shaped sliding plates 9 are fixedly installed on the inner sides of both the first fixed frame 5 and the second fixed frame 7, and a T-shaped sliding groove 10 is opened on one side of the inverter body 1. The T-shaped sliding plate 9 and the T-shaped sliding groove 10 are slidably connected.

[0029] By setting T-shaped sliding plate 9 and T-shaped sliding groove 10, the fixed frame 5 and fixed frame 7 can be limited, so that the fixed frame 5 and fixed frame 7 can be fixedly slid on one side of the inverter body 1.

[0030] Furthermore, a movable block 12 is fixedly installed on the inner side of the card plate 15, and a movable groove 11 is opened on one side of the inverter body 1. The movable block 12 is slidably connected to the movable groove 11. A limit rod 13 is fixedly installed on the inner wall of the movable groove 11. The limit rod 13 moves through the movable block 12. A spring 14 is surrounded on the outer wall of the limit rod 13. The spring 14 is fixedly installed between the outer wall of the movable block 12 and the inner wall of the movable groove 11.

[0031] By setting a limiting rod 13, the moving block 12 and the spring 14 can be limited to ensure the stability of the moving block 12 when moving and the spring 14 when compressed.

[0032] Furthermore, a storage shell 18 is provided on the outside of the fixed frame 2 7, and the storage shell 18 is fixedly installed on one side of the inverter body 1.

[0033] The storage shell 18 provides some protection for the cooling fan 8 in the fixed frame 7.

[0034] Furthermore, a dustproof grid plate 4 is provided on one side of the vent 3, and the dustproof grid plate 4 is fixedly installed on the other side of the inverter body 1. Dustproof nets 23 are fixedly installed on the inner walls of the first fixed frame 5 and the second fixed frame 7 near the outer side.

[0035] The dustproof grille 4 can provide some dust protection for the vent 3, and the dustproof net 23 can provide some dust protection for the heat dissipation vent 2.

[0036] Example 2:

[0037] Based on Embodiment 1, a preferred embodiment of the inverter heat dissipation structure provided by this utility model is, for example... Figures 1 to 6 As shown: The connecting assembly includes a fastening screw 21, a connecting block 19, and a connecting sleeve 20. The connecting sleeve 20 is fixedly installed at the bottom end of the first fixed frame 5, and the connecting block 19 is fixedly installed at the top end of the second fixed frame 7. The connecting sleeve 20 is sleeved on the outer wall of the connecting block 19. The fastening screw 21 is threadedly connected to the threaded holes opened on the connecting sleeve 20 and the connecting block 19. A knob 22 is fixedly installed at one end of the fastening screw 21.

[0038] Specifically, in the above technical solution, when personnel need to disassemble the fixed frame 5 and the fixed frame 7 to maintain the cooling fan 6, they can directly rotate the knob 22, causing the knob 22 to drive the fastening screw 21 to rotate, causing the fastening screw 21 to disengage from the connecting sleeve 20 and the connecting block 19. At this time, the fixed frame 5 is moved upward, causing the fixed frame 5 to drive the connecting sleeve 20 to disengage from the connecting block 19, thereby completing the disassembly between the fixed frame 5 and the fixed frame 7. Through the above structure, it is convenient for personnel to disassemble the fixed frame 5 and the fixed frame 7, thereby facilitating the maintenance of the cooling fan and ensuring the normal use of the cooling fan in the future. The structure is simple and highly practical.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
