However, when disassembling and replacing the biofilm, it is inconvenient to rotate the fixing bolts back and forth, which affects the applicability of the device.

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1
[0026] like Figure 1-4 As shown, this utility model provides a technical solution: an anti-scaling device for an IGBT radiator, including a radiator body 1, a cooling fan 5 installed inside the radiator body 1, a mounting base 4 disposed on the side wall of the radiator body 1, an anti-scaling box 2 fixedly installed on one side of the radiator body 1, and a connecting assembly 3 disposed on one side of the radiator body 1. The connecting assembly 3 includes a disassembly and assembly mechanism 31 disposed on one side of the radiator body 1, and a shock-absorbing mechanism 32 disposed on one side of the radiator body 1. The disassembly and assembly mechanism 31 includes an installation groove opened inside the anti-scaling box 2, into which an installation frame 311 is inserted. A filter plate 312 is fixedly installed inside the installation frame 311, and a slot 313 is opened on one side of the installation frame 311 to prevent scaling. The inside of the box 2 is provided with a rectangular groove 314. A rectangular column 315 is slidably connected to the inner wall of the rectangular groove 314. A fixed column 316 is fixedly connected to the inner wall of the rectangular groove 314. An ejector ring 317 is slidably connected to the outer wall of the fixed column 316. A first spring 318 is fixedly connected to the inner wall of the rectangular groove 314. The inside of the anti-scalding box 2 is provided with an inner groove 319. A movable block 3110 is slidably connected to the inner wall of the inner groove 319. An inclined plate block 3111 is fixedly connected to one side of the movable block 3110. A connecting rod 3113 is fixedly connected to the side of the movable block 3110 away from the inclined plate block 3111. A second spring 3112 is fixedly connected to the inner wall of the inner groove 319. A pull rod 3114 is fixedly connected to the outer end of the connecting rod 3113 through a limiting block.
[0027] In this embodiment, one end of the second spring 3112 is fixedly connected to the movable block 3110, and the inclined plate block 3111 is movably inserted through the mounting groove and the slot 313 for engagement. The outer end of the connecting rod 3113 is movably connected to the anti-scaling box 2. Through the cooperation of the mounting frame 311, the filter plate 312, and the anti-scaling box 2, dust and impurities can be filtered, thereby preventing dust and impurities from adhering to the surface of the cooling fan 5 and affecting the heat dissipation effect of the radiator body 1. Furthermore, through the cooperation of the slot 313, the rectangular groove 314, the rectangular column 315, the fixed column 316, the ejector ring 317, the first spring 318, the inner groove 319, the movable block 3110, the inclined plate block 3111, the second spring 3112, the connecting rod 3113, and the pull rod 3114, it is convenient to manually disassemble the mounting frame 311, thereby facilitating manual cleaning and replacement of the mounting frame 311 and the filter plate 312, and preventing the filter holes of the filter plate 312 from becoming clogged and affecting the air intake effect.
[0028] Furthermore, the rectangular column 315 is fixedly connected to the mounting frame 311, the rectangular column 315 is slidably connected to the outer wall of the fixed column 316, and one end of the first spring 318 is fixedly connected to the ejector ring 317.
[0029] In use, the device first involves manually installing the cooling fans 5 on both sides of the radiator body 1 and the IGBTs. The radiator body 1 then provides cooling to the IGBTs. When the cooling fans 5 are operating, the mounting frame 311, filter plate 312, and anti-scaling box 2 prevent external dust and impurities from adhering to their surface, thus achieving an anti-scaling effect. Furthermore, when the mounting frame 311 needs to be disassembled, simply hold the pull rod 3114 and pull the connecting rod 3113 outwards. This causes the movable block 3110, fixedly connected to the inner end of the connecting rod 3113, to move the inclined locking block 3111 outwards simultaneously, separating the inclined locking block 3111 from the slot 313. Then, under the elastic force of the first spring 318, the ejector ring 317 presses upwards against the rectangular column 315. Since the rectangular column 315 is fixedly connected to the mounting frame 311,... This allows the mounting frame 311 to pop upwards, and then the mounting frame 311 and filter plate 312 can be manually removed, facilitating manual cleaning and replacement of the filter plate 312. When the mounting frame 311 needs to be installed, it can be manually inserted into the mounting groove, with the rectangular column 315 engaging with the rectangular groove 314. When the mounting frame 311 enters the mounting groove, it will press against the inclined block 3111. Since the upper part of the inclined block 3111 is inclined, it can be pressed into the inner groove 319. After the mounting frame 311 and the mounting groove are fully engaged, the second spring 3112, under the action of elasticity, can cause the movable block 3110 to move the inclined block 3111 outwards, allowing the inclined block 3111 to engage with the slot 313, thus achieving a fixed effect on the mounting frame 311. The installation operation is simple and convenient. Example 2
[0030] Based on Embodiment 1, a preferred embodiment of the anti-scaling device for IGBT heat sinks provided by this utility model is as follows: Figures 1 to 4 As shown: The shock absorption mechanism 32 includes a groove 321 formed inside the mounting base 4. A mounting block 322 is slidably connected to the inner wall of the groove 321. A damper 327 is fixedly installed on the inner wall of the groove 321. A sliding groove 323 is formed on the inner wall of the groove 321. A sliding rod 324 is fixedly connected to the inner wall of the sliding groove 323. A connecting block 325 is slidably connected to the outer wall of the sliding rod 324. A third spring 326 is fixedly connected to the inner wall of the groove 321.
[0031] In this embodiment, the mounting block 322 is fixedly connected to the side wall of the radiator body 1, and the top of the damper 327 is fixedly connected to the mounting block 322. Through the cooperation of the groove 321, the mounting block 322, the slide groove 323, the slide rod 324, the connecting block 325, the third spring 326, and the damper 327, when the radiator body 1 is installed through the mounting base 4, it can play a shock absorption effect on the radiator body 1, thereby preventing the radiator body 1 from being damaged by vibration during use, thus extending the service life of the parts.
[0032] Furthermore, one end of the third spring 326 is fixedly connected to the connecting block 325, and one side of the connecting block 325 is fixedly connected to the mounting block 322.
[0033] When the heat sink body 1 is connected to the IGBT via the cooling fan 5, and when it is subjected to external force and vibrates, the mounting block 322 is fixedly connected to the side wall of the heat sink body 1. Under the action of gravity, the mounting block 322 can slide relative to the groove 321. Since the connecting block 325 is fixedly connected to the mounting block 322, the connecting block 325, which is fixedly connected to the side wall of the mounting block 322, can slide relative to the sliding groove 323 via the sliding rod 324. This causes the third spring 326 to deform, and with the cooperation of the damper 327, it can play a shock absorption role, thereby protecting the heat sink body 1 and extending the service life of the heat sink body 1.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
