Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat dissipation devices for switches, and specifically to a removable heat dissipation device used in audio and video transmission equipment. Background Technology
[0002] Existing high-power devices typically have built-in cooling fans for better heat dissipation. However, over time, these fans accumulate dust or fail due to lifespan limitations, preventing the heat generated inside the device from dissipating effectively. This can lead to poor chip performance and, in severe cases, even system crashes, effectively ending the device's lifespan. Replacing the cooling fan is often difficult due to the device's enclosed casing, requiring professional disassembly or even returning it to the manufacturer for repair. The process is neither user-friendly nor convenient.
[0003] Currently, in the field of switches, there is a type of removable fan device that allows a broken fan assembly to be quickly pulled out from the outside of the device by pressing a latch, and a new fan assembly can be inserted, thereby improving product lifespan. However, existing removable fan devices still have the following drawbacks:
[0004] (1) The fan device has a relatively large structure and complex sheet metal bending structure. It requires stamping grooves on all four sides for pasting and fixing conductive foam. At the same time, studs need to be made inside the sheet metal to provide a position for fixing the fan, resulting in high overall cost.
[0005] (2) Conductive foam is used in the fan device as a buffer for the gaps in the plug-in structure, and also as a bridge for grounding. Although conductive foam has elastic cushioning, its textile material determines that it is not wear-resistant, and its elasticity and conductivity will be affected over time.
[0006] (3) The clip structure of the fan device is located on the bottom surface. When the device is placed on the desktop or inside the server rack, the clip is very close to the desktop, making it inconvenient for users to operate. Utility Model Content

[0010] As a further improvement of this utility model, it also includes a locking lever, which is installed on one side of the front panel of the bracket body. The side of the locking lever is provided with an elastic buckle. When the locking lever is pressed, the elastic buckle can be engaged or disengaged from the housing of the high-power equipment.
[0011] As a further improvement of this utility model, it also includes a PCB board, which is mounted on the bottom panel of the bracket body. The PCB board is provided with gold fingers. When the handle is pulled to insert or remove the heat dissipation device, the gold fingers can be connected to or disconnected from the preset female socket inside the high-power device.
[0012] As a further improvement of this utility model, the fan is provided with a power cord and a power cord terminal, which are located between the PCB board and the bottom panel of the bracket body.

[0034] Example
[0035] like Figure 1 , Figure 2 and Figure 3As shown, the removable heat dissipation device of this utility model includes a bracket body 1, a handle 2, spring contacts 3, and a fan 5. The handle 2 is mounted on the front panel 115 of the bracket body 1 to facilitate movement of the bracket body 1. The fan 5 is mounted on the inner side of the bracket body 1 to provide cooling air. Multiple spring contacts 3 are arranged around the outer periphery of the bracket body 1 along the direction of its retraction and insertion movement, and the spring contacts 3 are used to achieve a clearance fit between the bracket body 1 and the housing of a high-power device.
[0036] In this embodiment, by arranging multiple spring plates 3 around the outer perimeter of the bracket body 1 along the insertion and removal direction of the bracket body, the elastic buffering effect provided by the spring plates 3 achieves a clearance fit between the bracket body 1 and the outer shell of the high-power equipment. This avoids the inability of the heat dissipation device to operate due to manufacturing and assembly tolerances. The heat dissipation structure can be inserted and removed from the outside of the high-power equipment, enabling convenient replacement of the heat dissipation device without opening the equipment shell. This ensures the stable operation of the high-power equipment, thereby extending the service life of the high-power equipment and reducing costs.
[0037] like Figure 1 and Figure 2 As shown, it also includes a latching lever 4. The latching lever 4 is installed on one side of the front panel 115 of the bracket body 1. The side of the latching lever 4 is provided with an elastic buckle 41. When the latching lever 4 is pressed, the elastic buckle 41 is engaged or disengaged from the housing of the high-power equipment.
[0038] The heat dissipation device of this embodiment can be applied to video transmission equipment in the broadcasting and television industry. When the fan 5 in the heat dissipation device stops due to a large amount of dust accumulation or the drying of bearing lubricating oil, the latching lever 4 can be pressed very conveniently, and the entire heat dissipation device can be pulled out of the equipment through the handle 2, thereby replacing the heat dissipation device and extending the service life of the entire equipment.
[0039] In this embodiment, the bracket body 1 is a sheet metal part. Different holes are made on a flat sheet metal part with a thickness of 0.8mm to 1.0mm. Without complex stamping and bending structures, the bracket body 1 is obtained by simply bending it into shape by a few 90° bends and then riveting two screw posts 10.
[0040] In this embodiment, both the spring 3 and the latching lever 4 are made of beryllium copper, which has good elasticity. Furthermore, the spring 3 has good electrical conductivity, ensuring proper grounding between the heat dissipation device and the equipment casing, thus improving the operational safety of the heat dissipation device.
[0041] like Figure 1As shown, it also includes a PCB board 6. The PCB board 6 is mounted on the bottom panel 114 of the bracket body 1, and the PCB board 6 is provided with gold fingers 7. When the handle 2 is pulled to insert or remove the heat dissipation device, the gold fingers 7 can be connected or disconnected from the preset female socket inside the high-power device.
[0042] like Figure 3 As shown, the fan 5 is equipped with a power cord 51 and a power cord terminal 52, which are located between the PCB board 6 and the bottom panel 114 of the bracket body 1.
[0043] like Figure 4 and Figure 5 As shown, the front panel 115 has a second threaded hole 104 arranged diagonally for mounting the handle 2. By screwing the first fastening screw 8 into the second threaded hole 104, the handle 2 is mounted at a 45° angle, which is ergonomic and allows the four fingers (excluding the thumb) to be held comfortably by the user in their natural position.
[0044] Furthermore, the front panel 115 is provided with multiple heat dissipation holes 103 to achieve cooling airflow and improve heat dissipation.
[0045] like Figure 4 and Figure 7 As shown, the bracket body 1 also includes a top panel 110, a first side panel 111, and a second side panel 113. The top panel 110, the first side panel 111, the second side panel 113, and the bottom panel 114 are each provided with a plurality of first mounting holes 102 in a rectangular structure for mounting spring clips 3. The spring clips 3 can be fastened into the first mounting holes 102, making them easy to install and remove.
[0046] like Figure 4 and Figure 6 As shown, the first side panel 111 has a third threaded hole 105 and a limiting hole 106 on both sides, with the limiting hole 106 close to the front panel 115. The lower side of the front panel 115 has a second mounting hole 108; one end of the latching lever 4 has a fifth threaded hole 42, and a second fastening screw 9 is screwed into the fifth threaded hole 42 and the third threaded hole 105. This connects and fixes one end of the latching lever 4 to the front panel 115, while the other end of the latching lever 4 passes through the second mounting hole 108 and extends to the outside of the bracket body 1; the elastic buckle 41 passes through the limiting hole 106, and a limiting groove is provided in the corresponding part inside the high-power equipment. Pressing the latching lever 4 causes deformation, which moves the elastic buckle 41 in the limiting hole 106 and the limiting groove. Releasing the latching lever 4 allows the elastic buckle 41 to spring back to its original position in the limiting hole 106 and the limiting groove. Once the elastic buckle 41 moves to a preset distance in the limiting hole 106 and the limiting groove, the heat dissipation device can be pulled out from inside the high-power equipment.
[0047] In other embodiments, the end of the latching lever 4 and the third threaded hole 105 can be connected by rivets or welded.
[0048] like Figure 4 and Figure 8 As shown, the bracket body 1 also includes a first rear panel 109 and a second rear panel 112. Both the first rear panel 109 and the second rear panel 112 are provided with first threaded holes 101 for fixing the fan 5. Specifically, an arc-shaped through hole is formed between the first rear panel 109 and the second rear panel 112 to facilitate the blowing of cooling air towards high-power equipment. The fan 5 has sixth threaded holes 53 at its four corners. A directional slot is formed at the top of the bracket body 1. The fan 5 is inserted downwards through the square slot at the top of the bracket body 1, and then secured in place by four third fastening screws 11 into the first threaded holes 101 and the sixth threaded holes 53, thus fixing the fan 5 inside the bracket body 1.
[0049] like Figure 4 and Figure 9 As shown, two screw posts 10 are riveted to the bottom panel 114, and two seventh threaded holes 61 are provided on the PCB board 6. The 3-pin power cable 51 of the fan 5 is connected to the female connector on the PCB board 6. The PCB board 6 is fixed to the seventh threaded holes 61 and the screw posts 10 of the bottom panel 114 by two fourth fastening screws 12 with spring washers, thus completing the assembly of all components. When the heat dissipation device is inserted into the chassis, the gold fingers 7 connect with the pre-set female connector inside the device, and the elastic clips 41 cooperate with the relevant parts of the device housing to complete the installation.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
