Description
Technical Field
[0001] This utility model relates to the field of inverter heat sink technology, and in particular to an inverter heat sink with a detachable air guide cover. Background Technology
[0002] Power devices in frequency converters, such as IGBTs (Insulated Gate Bipolar Transistors), experience power losses during operation, which are converted into heat. If not dissipated promptly, the device temperature will continuously rise. The performance and lifespan of electronic components are highly sensitive to temperature; excessively high temperatures can cause changes in component parameters, reducing their efficiency and reliability, and even leading to component damage, thus affecting the normal operation of the frequency converter. Heat sinks can quickly dissipate this heat, keeping power devices and other electronic components operating within a suitable temperature range, thereby protecting their performance and lifespan.
[0003] However, existing inverter heat sinks are relatively weak in terms of manual disassembly of the air guide cover, making it inconvenient to clean the dust accumulated inside the inverter heat sink, greatly reducing the heat dissipation effect. In addition, uneven heat dissipation can lead to thermal stress inside the inverter. Differences in thermal expansion between different components can cause mechanical deformation, loose connections and other problems, further affecting the performance and reliability of the equipment. Therefore, an inverter heat sink with a detachable air guide cover is proposed to solve the above problems. Utility Model Content

[0032] 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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a frequency converter heat sink with a detachable air guide cover, including an air guide shell 1, which is designed to guide the airflow in a directional manner to optimize heat dissipation efficiency, and a heat sink 2, which is designed as the core component of the heat sink. The air guide shell 1 is slidably connected to the outside of the heat sink 2. A rotating handle 3 is rotatably connected inside the heat sink 2. The rotating handle 3 is designed to unlock / lock the air guide shell 1 by manual rotation without tools, improving the convenience of disassembly and assembly. A rotating plate 4 is fixedly connected to the top of the rotating handle 3. The rotating plate 4 is designed to affect the locking and releasing states. The outside of the rotating plate 4 is rotatably connected to the inside of the heat sink 2. Multiple rotating arms 5 are rotatably connected to the outside of the rotating plate 4. The rotating arms 5 are designed to convert rotational motion into linear motion.
[0034] The rotating arm 5 is externally fixedly connected to a locking block 6. This locking block 6 serves as a locking mechanism to ensure the air guide shell 1 is securely installed. Multiple locking blocks 6 are externally engaged with the interior of the air guide shell 1. The external parts of the locking blocks 6 are slidably connected to the interior of the heat sink 2. A retaining plate 7 is fixedly connected to the top of the locking blocks 6. This retaining plate 7 serves as a limiter, restricting the movement range of the rotating arm 5. The external parts of the retaining plate 7 are slidably connected to the interior of the heat sink 2. The heat sink 2 has multiple retaining grooves 8 inside. These grooves provide sliding tracks for the locking blocks 6, ensuring they move along a fixed path and preventing deviation or jamming. The external parts of the retaining plate 7 are slidably connected to the outside of the retaining grooves 8. The air guide shell 1 has multiple locking slots 9 inside. These slots 9 form a plug-in locking mechanism with the locking blocks 6, enabling quick fixing of the air guide shell 1 and the heat sink 2. The external parts of the locking blocks 6 are engaged with the outside of the locking slots 9. A fixing component for installing and fixing the air guide cover is fixedly connected inside the heat sink 2.
[0035] Reference Figures 4 to 6 The fixing component includes a clamping plate 10, which is designed as a base for fixing the component and provides support for the installation of other components. The clamping plate 10 is fixedly connected to the outside of the heat sink 2. The bottom end of the heat sink 2 is fixedly connected to a spiral post 11, which is designed to provide adjustable mechanical locking force. Both the spiral post 11 and the rotating handle 3 have spiral threads on their exteriors. The spiral post 11 is spirally connected to the outside of a spiral shaft 12, which is designed as a nut structure sleeved on the spiral post 11 and moves up and down along the thread when rotating. The spiral shaft 12 is spirally connected to the outside of the rotating handle 3.
[0036] A spring 13 is fixedly connected inside the clamping plate 10. The spring 13 is designed here as an elastic buffer. A locking ball 14 is fixedly connected outside the spring 13. The locking ball 14 is designed here as a quick positioning and auxiliary locking. A "click" sound indicates that it is in place when installed. When disassembling, it needs to be pulled out with a little force. The locking ball 14 is externally engaged with the outside of the spiral shaft 12, and the locking ball 14 is externally slidably connected to the inside of the clamping plate 10.
[0037] Working principle: When it is necessary to facilitate the disassembly and installation of the air guide cover outside the inverter heat sink, slide the air guide cover 1 to the outside of the heat sink 2. At this time, rotate the handle 3 to rotate, which in turn drives the rotating plate 4 to rotate. When the rotating plate 4 rotates, it drives the multiple rotating arms 5 connected to it to rotate, which in turn pushes the locking blocks 6 connected to the rotating arms 5 to slide in the sliding groove 8 in the heat sink 2 on the top binding slide plate 7, keeping the trajectory running smoothly. This pushes the multiple locking blocks 6 outward and into the locking groove 9 in the air guide cover 1, so that the locking is completed. When disassembly is required, rotate the handle 3 in the opposite direction to reverse the above operation, so that the locking blocks 6 are disengaged from the locking groove 9, thus achieving the purpose of easy disassembly.
[0038] When installing the air guide cover to prevent instability caused by external factors during use, after the air guide cover and radiator are installed, the handle 3 is rotatably connected to the spiral column 11. At this time, the spiral shaft 12 is rotatably connected to the handle 3 and the external spiral pattern of the spiral column 11, so that the spiral shaft 12 enters the clamping plate 10. Because the multiple springs 13 and the clamping ball 14 inside the clamping plate 10 are subjected to the elastic force of the spring 13, the clamping ball 14 is pushed to engage with the external pattern of the spiral shaft 12, thereby making the handle 3 firmly fixed and preventing external factors from causing the handle 3 to rotate, which would affect the installation of the air guide cover and radiator.
[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
