[0033] Please refer to Figures 1-4 A high-frequency filter heat dissipation assembly includes: a filter body 1 with a heat sink 2 mounted on the front side; a heat sink substrate 3 mounted on the side of the heat sink 2 near the filter body 1, with the heat sink substrates 3 on both sides tightly attached to the sides of the filter body 1; a heat dissipation assembly 4 disposed between the heat sink substrate 3 and the heat sink 2; an installation groove 7 opened on the side of the heat sink 2 away from the filter body 1, a cooling fan 5 installed on the inner wall of the installation groove 7, and a disassembly and assembly assembly 6 disposed between the cooling fan 5 and the heat sink 2.
[0034] Please refer to Figure 2 The heat dissipation assembly 4 includes multiple sets of parallel heat dissipation fins 401 mounted on the outer side of the heat dissipation substrate 3. Each set of heat dissipation fins 401 is vertically fixed to the outer side of the heat dissipation substrate 3. A heat dissipation channel 403 is formed between two adjacent sets of heat dissipation fins 401. The heat dissipation fins 401 are wavy in shape and have ventilation holes 402. An air guide groove 404 is formed inside the heat dissipation block 2. The air outlets on both sides of the air guide groove 404 are perpendicular to it. The air outlets on both sides of the air guide groove 404 correspond to the multiple sets of heat dissipation fins 401 on the upper and lower sides. A through slot 405 is provided between the 04 and the mounting slot 7. A diverter block 406 is installed at the bottom of the air guide 404. The diverter block 406 is raised in the middle and extends downward in an arc shape on both sides. Arc-shaped guide blocks 407 are provided at the corners of the vertical air outlets on both sides of the air guide 404. Air guide plates 408 are installed on the outer sides of the air outlets on both sides of the air guide 404. The two air guide plates 408 face the multiple sets of heat dissipation fins 401 on the upper and lower sides respectively. When the high-frequency filter body 1 generates heat during operation, the heat is first conducted to the heat dissipation substrate 3, which is in close contact with both sides of the filter body 1. Since the heat dissipation substrate 3 has a large contact area with the filter body 1, it can efficiently absorb heat. Subsequently, the heat is transferred to the heat dissipation fins 401 installed on the outer side of the heat dissipation substrate 3. The wave-shaped heat dissipation fins 401 increase the heat dissipation area, and the ventilation holes 402 on them further enhance airflow, allowing heat to be quickly dissipated into the surrounding environment. After the cooling fan 5 is turned on, the airflow enters the air guide slot 404 through the mounting slot 7 and the through slot 405. The diverting block 406 at the bottom of the air guide slot 404, with its raised middle and arc-shaped downward extension on both sides, can evenly divert the airflow to both sides; the guide blocks 407 at the corners of the vertical air outlets on both sides use an arc design to reduce airflow resistance and guide the airflow to flow more smoothly; the air guide plates 408 on the outer sides of the air outlets on both sides of the air guide slot 404 precisely guide the airflow to the heat dissipation fins 401 on the upper and lower sides, accelerate the airflow in the heat dissipation channel 403, and quickly remove the heat from the heat dissipation fins 401.
[0035] Please refer to Figure 3 and 4The heat sink 2 has mounting holes 8 on both its upper and lower sides that communicate with the mounting groove 7. The disassembly and assembly assembly 6 includes a fixing pin 601 that slides into the inner wall of the mounting hole 8. The inner walls of both the upper and lower sides of the heat sink 2 have limiting grooves 602 that communicate with the mounting holes 8 and are located on the same central axis. A limiting plate 603 that slides into the inner wall of the limiting groove 602 is installed around the fixing pin 601. A spring 604 is installed between one side of the limiting plate 603 and the inner wall of the limiting groove 602. The cooling fan 5 has mounting holes 8 on both sides. The mounting slots 605 cooperate with the fixing pins 601. For the installation and removal of the cooling fan 5, when it is necessary to install the cooling fan 5, place the cooling fan 5 in the mounting slot 7, and push the fixing pins 601 to insert them into the fixing slots 605 on both sides of the cooling fan 5. At this time, the limiting plate 603 slides within the limiting slot 602, and the spring 604 is compressed. When the fixing pins 601 are fully inserted into the fixing slots 605, the spring 604 returns to its original shape, pushing the limiting plate 603 to securely fix the cooling fan 5. For disassembly, press the fixing pins 601 to compress the springs 604, causing the fixing pins 601 to disengage from the fixing slots 605, allowing the cooling fan 5 to be removed, thus achieving convenient installation and removal.
