Description

Technical Field

[0001] This utility model relates to the field of inverter technology, specifically to a temperature regulation mechanism for inverters. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) energy (from batteries or storage batteries) into alternating current (AC) energy with fixed frequency and voltage or adjustable frequency and voltage. It consists of an inverter bridge, control logic, and filter circuits. It is widely used in air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, and more.

[0003] When existing inverters are working, they usually dissipate heat through internal cooling fans. The electrical components (resistors, capacitors, inductors, transistors, diodes) operate in different states at different temperatures. The external temperature affects the internal temperature of the inverter. High temperatures can easily burn out the electrical components inside the inverter, while low temperatures can affect the electrical components inside the inverter, resulting in a decrease in the inverter's working efficiency.

[0004] According to announcement number CN216356505U, a fast aluminum heat sink for inverters includes an inverter body, heat dissipation vents on both the left and right ends of the inverter body, and a mounting plate connected to the upper surface of the inverter body. A first fan box and a second fan box are respectively located on the left and right sides of the inverter body. Both the first and second fan boxes have fans installed inside. The inner surfaces of both fan boxes are connected to limit rods. Air inlets are opened on the outer surfaces of both fan boxes. Water tanks are connected to the rear surfaces of both fan boxes, and water inlets are opened on the upper surface of the water tanks. This utility model, through its series of structures, can be applied to inverters of different sizes, is easy to install and disassemble, and simultaneously provides air cooling and water cooling, resulting in high heat dissipation efficiency.

[0005] The heat sink described above only dissipates heat. The electrical components operate differently at different temperatures. The external temperature affects the internal temperature of the inverter. Higher temperatures can easily burn out the electrical components inside the inverter, while lower temperatures can also affect the electrical components inside the inverter, leading to a decrease in the inverter's operating efficiency. Therefore, we need to propose a temperature regulation mechanism for inverters. Utility Model Content

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

[0024] Please see Figure 1-5 This utility model provides a temperature regulation mechanism for an inverter, including an inverter housing 1. Both ends of the inverter housing 1 have heat dissipation vents 2, and the inner cavity of each heat dissipation vent 2 is equipped with a dustproof mesh. Movable grooves 3 are provided on both sides of the top of the inverter housing 1. A movable seat 4 is slidably connected to the inner cavity of the movable groove 3. A cleaning seat 5 is provided at the bottom of the movable seat 4. A disassembly and assembly mechanism 6 for easy disassembly and assembly is provided at the top of the cleaning seat 5. A cleaning brush 7 is provided on the inner side wall of the cleaning seat 5. A temperature display 8 is installed on the upper surface of the inverter housing 1. A temperature sensor and a cooling fan 9 are installed inside the inverter housing 1, and four sets of cooling fans 9 are provided.

[0025] When the inverter is working, the temperature sensor senses the internal temperature of the inverter. The temperature sensed by the temperature sensor is displayed externally on the temperature display 8. The user observes the displayed temperature and determines the number of cooling fans 9 that need to be started. By controlling the heat dissipation speed, the internal temperature of the inverter is regulated, thereby regulating the temperature of the inverter during operation, improving the temperature stability of the inverter during operation, and improving the working efficiency of the inverter.

[0026] A rubber pad 10 is attached to the top of the movable base 4. The surface of the rubber pad 10 has anti-slip grooves. The rubber pad 10 makes it easy for the user to push the movable base 4 to move, avoiding friction between the user's hand and the movable base 4. The anti-slip grooves increase the friction between the rubber pad 10 and the user's hand, making it easier to move the movable base 4.

[0027] The surface of the movable seat 4 has a through hole, and a support rod 11 is inserted and slidably connected to the inner cavity of the through hole of the movable seat 4. Both ends of the support rod 11 are fixedly connected to the inner side wall of the movable groove 3. The support rod 11 provides support for the weight on the movable seat 4 and assists the movable seat 4 to slide in the movable groove 3, thereby improving the stability of the movable seat 4 when it moves in the movable groove 3.

[0028] The disassembly and assembly mechanism 6 includes a locking block 61 and an adjustment groove 62. The locking block 61 is slidably connected to the inner cavity of the adjustment groove 62. A slot 63 is provided on the lower surface of the movable seat 4. The locking block 61 is engaged with the inner cavity of the slot 63. A lever 64 is fixedly connected to the surface of the locking block 61. The other end of the lever 64 passes through the adjustment groove 62 and extends to the outside of the cleaning seat 5. Two sets of locking blocks 61 are provided. An elastic component for assisting reset is provided between the two sets of locking blocks 61. The adjustment groove 62 is provided on the upper surface of the cleaning seat 5. When disassembling, pressing the lever 64 at both ends moves the locking block 61 inward to squeeze the elastic component. At the same time, the locking block 61 moves out of the inner cavity of the slot 63, and the cleaning seat 5 can be removed from the movable seat 4. When installing, pressing the lever 64 at both ends inserts the locking block 61 into the slot 63. When released, the elastic component pushes the locking blocks 61 at both ends to reset, so that the locking block 61 moves into the inside of the slot 63, realizing the locking operation.

[0029] The elastic component includes a slide rod 65, and a through hole is provided at the bottom end of the locking block 61. The slide rod 65 is inserted into and slides in the inner cavity of the through hole of the locking block 61. Both ends of the slide rod 65 are fixedly connected to the inner side wall of the adjustment groove 62. A spring 66 is sleeved on the outer surface of the slide rod 65. The spring 66 is located between the two sets of locking blocks 61. The slide rod 65 can assist the locking blocks 61 in moving within the adjustment groove 62, improving the stability of the locking blocks 61 during movement. The spring 66 can also be released to push the locking blocks 61 at both ends back to their original positions, thus assisting in the installation of the cleaning seat 5 and the moving seat 4.

[0030] A semiconductor cooling module 12 is installed inside the inverter housing 1. A conduction rod 13 is fixedly connected to the surface of the semiconductor cooling module 12. The conduction rod 13 is located at the air outlet of the cooling fan 9. When the semiconductor cooling module 12 is activated, it cools the conduction rod 13. The air at the air outlet of the cooling fan 9 is cooled through the conduction rod 13. The cooled air is then blown by the cooling fan 9 to the electrical components to improve the heat dissipation speed.

[0031] The semiconductor cooling module 12 includes heat sink fins, a semiconductor cooling chip, and a gold-plated plate. The semiconductor cooling chip is mounted on a heat sink, and the gold-plated plate is mounted on the cooling end of the semiconductor cooling chip. The gold-plated plate is bonded to the cold end of the semiconductor cooling chip with thermally conductive silicone. The gold-plated plate is connected to the conductive rod 13 to cool the conductive rod 13. At the same time, the hot end of the semiconductor cooling chip is connected to the heat sink fins, and the heat from the hot end of the semiconductor cooling chip is transferred to the heat sink fins for heat dissipation.

[0032] A fixing post 14 is fixedly connected to the top of the cleaning seat 5, and a fixing groove 15 is provided on the lower surface of the movable seat 4. The fixing post 14 and the inner cavity of the fixing groove 15 are engaged and locked together. The engagement of the fixing post 14 and the fixing groove 15 improves the stability of the cleaning seat 5 when it moves on the movable seat 4 and prevents the angle of the cleaning seat 5 from shifting when it moves.

[0033] The semiconductor cooling module 12 includes heat sink fins, a semiconductor cooling chip, and a gold-plated plate. The semiconductor cooling chip is mounted on a heat sink, and the gold-plated plate is mounted on the cooling end of the semiconductor cooling chip. The gold-plated plate is bonded to the cold end of the semiconductor cooling chip with thermally conductive silicone. The gold-plated plate is connected to the conductive rod 13 to cool the conductive rod 13. At the same time, the hot end of the semiconductor cooling chip is connected to the heat sink fins, and the heat from the hot end of the semiconductor cooling chip is transferred to the heat sink fins for heat dissipation.

[0034] A fixing post 1414 is fixedly connected to the top of the cleaning seat 55, and a fixing groove 1515 is provided on the lower surface of the movable seat 44. The fixing post 1414 and the inner cavity of the fixing groove 1515 are engaged and locked. The engagement of the fixing post 1414 and the fixing groove 1515 improves the stability of the cleaning seat 55 when it moves on the movable seat 44 and prevents the angle of the cleaning seat 55 from shifting when it moves.

[0035] Electronic components such as resistors, capacitors, inductors, transistors, and diodes are mounted on a circuit board, which is then fixed in the middle of the inverter housing 1 using bolts. This method of mounting electronic components in the middle of the inverter housing 1 avoids the movement paths of the moving base 4 and the cleaning base 5, ensuring that they do not interfere with each other.

[0036] The cooling fan 9 is connected to a control switch via a power cord. At the same time, the cooling fan 9 is connected to the circuit board inside the inverter housing 1 via a power cord. The cooling fan 9 is a mature existing technology. This utility model does not provide any further protection or limitation for the cooling fan 9. Products with equivalent functions can be purchased on the market for the cooling fan 9.

[0037] When cleaning the dust on the surface of the dust filter, such as when cleaning the dust filter on the right side of the inverter, the outlet of the right heat dissipation port 2 can be blocked using a collection box or a dust plate. Then, turn on the left cooling fan 9 to blow air through the right dust filter, allowing air to be discharged through the right dust filter. At this time, the movable seats 4 at both ends can be pushed to move. When the movable seats 4 move the cleaning seat 5 at the bottom, the cleaning brush 7 rubs the surface of the dust filter. During the friction, the surface of the dust filter shakes, causing the dust to fall off. The fallen dust is blown to the collection box and / or dust plate on the right side for collection, preventing dust from flying around during cleaning and preventing dust from entering the inner cavity of the inverter housing 1 during cleaning.

[0038] Temperature sensor 16 and temperature display 8 are connected via a power cord. At the same time, temperature sensor 16 and temperature display 8 are connected to the circuit board inside the inverter housing 1 via the power cord. The connection method between temperature sensor 16, temperature display 8 and circuit board is a mature existing technology. This utility model does not provide any further protection or limitation for temperature sensor 16 and temperature display 8.

[0039] The working principle of this utility model is as follows: When the inverter is working, the temperature sensor senses the internal temperature of the inverter. The temperature sensed by the temperature sensor is displayed externally through the temperature display 8. The user observes the displayed temperature and determines the number of cooling fans 9 that need to be started. By controlling the heat dissipation speed, the temperature inside the inverter is regulated. After long-term use, the movable seats 4 at both ends can be pushed to move. When the movable seats 4 move the cleaning seat 5 at the bottom, the cleaning brush 7 cleans the surface of the dustproof screen to prevent dust from accumulating for a long time and causing the dustproof screen to become blocked. When disassembling, press the levers 64 at both ends to move the locking block 61 inward to squeeze the spring 66. At the same time, the locking block 61 moves out of the inner cavity of the locking slot 63, and the cleaning seat 5 can be removed from the movable seat 4. During installation, press the levers 64 at both ends again to insert the locking block 61 into the inner cavity of the slot 63. Then release the levers 64 to allow the spring 66 to return and push the locking block 61 to reset. The locking block 61 moves into the slot 63 to complete the locking, which makes it convenient for the user to replace the cleaning structure. This allows for the adjustment of the inverter's operating temperature, improving the stability of the inverter's operating temperature and increasing the inverter's operating efficiency.
