Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, and in particular to a filter cavity with a heat dissipation structure. Background Technology
[0002] A filter is a circuit or device used to process signals. It achieves the filtering effect by changing the frequency characteristics of the signal. Depending on the different properties of its transfer function, filters play an important role in fields such as electronic circuits, communication systems, audio processing, and image processing.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: due to the relatively small size of some filters, the heat sink area is small, which limits its heat dissipation effect. Poor heat dissipation will cause the internal components of the filter to overheat, which can easily cause damage to the components or reduce their performance, thereby affecting the normal operation of the filter.
[0004] Therefore, this utility model provides a filter cavity with a heat dissipation structure. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where some filters are relatively small in size, resulting in small heat sink areas that limit their heat dissipation effect and thus affect the normal operation of the filters. Therefore, this invention proposes a filter cavity with a heat dissipation structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a filter cavity with a heat dissipation structure, comprising a filter body, a heat dissipation device on the surface of the filter body, the heat dissipation device comprising two heat sinks, the surfaces of the two heat sinks being slidably connected to the filter body, two square plates being fixedly installed on the surfaces of the two heat sinks, a positioning rod being fixedly inserted inside the heat sinks, a rotating plate being rotatably sleeved on the arc surface of the positioning rod, a limiting groove being formed on the surface of the rotating plate, two pins being fixedly installed on the surface of the filter body, the surfaces of the pins abutting against the inner wall of the limiting groove, an elastic sleeve being fixedly sleeved on the surface of the pins, and the surface of the elastic sleeve abutting against the rotating plate.
[0007] The effect achieved by the above components is that by setting up a heat dissipation device, the heat dissipation area of the filter can be increased, the heat dissipation effect of the filter can be improved, the internal components of the filter will not overheat, and the performance of the filter can be improved.
[0008] Preferably, an elastic pad is fixedly mounted on the surface of the filter body, and the surface of the elastic pad abuts against the two rotating plates.
[0009] The effect achieved by the above components is that the elastic pad presses against the two rotating plates with elastic force, thereby assisting in fixing the rotating plates.
[0010] Preferably, a card plate is fixedly mounted on the surface of the filter body, and the surface of the card plate is slidably connected to two square plates.
[0011] The effect achieved by the above components is that the pallet allows workers to easily place the square board in the required position.
[0012] Preferably, an iron plate is fixedly installed inside both of the rotating plates, and a magnet is fixedly installed on the surface of both of the heat sinks.
[0013] The effect achieved by the above components is as follows: when the rotating plate is rotated, after the rotating plate rotates to a certain angle, the iron plate on the rotating plate comes into contact with the magnet. At this time, the rotating plate cannot rotate due to the limitation of the iron plate and the magnet, thus achieving the effect of restricting the rotation of the rotating plate.
[0014] Preferably, the surfaces of the two heat sinks are provided with a cleaning structure, the cleaning structure including two support frames, the surfaces of the two support frames are respectively fixedly connected to the two support frames, the surfaces of the support frames are slidably fitted with fixed frames, the surfaces of the fixed frames are uniformly fixedly mounted with a plurality of mounting plates, the surfaces of the mounting plates are fixedly fitted with cleaning sleeves, and the surfaces of the cleaning sleeves are slidably connected to the heat sinks.
[0015] The effect achieved by the above components is that by setting up a cleaning structure, it is convenient for staff to clean the dust on the heat sink, which improves the heat dissipation effect of the heat sink and allows the heat sink to dissipate heat better.
[0016] Preferably, each of the two fixing frames has two limiting wheels rotatably connected inside, and the surface of the limiting wheels is slidably connected to the support frame.
[0017] The effect achieved by the above components is that the fixing frame can slide along the surface of the support frame with the support of the limiting wheel, thus achieving the effect of assisting the sliding of the fixing frame.
[0018] Preferably, both of the fixing frames are internally threaded with extrusion frames, and the surface of the extrusion frames abuts against the heat sink.
[0019] The effect achieved by the above components is as follows: when the extrusion frame is rotated, the extrusion frame moves towards the heat sink with the help of the screw thread. After the extrusion frame moves a certain distance, the surface of the extrusion frame presses against the heat sink. At this time, the fixed frame cannot slide, thus achieving the effect of restricting the sliding of the fixed frame.
[0020] In summary:
[0021] 1. In this utility model, when the heat dissipation effect of the filter is poor, two heat sinks are fixed on the filter. At this time, the heat sinks can assist the filter in dissipating heat. By setting up a heat dissipation device, the heat dissipation area of the filter can be increased, the heat dissipation effect of the filter can be improved, the internal components of the filter will not overheat, and the performance of the filter can be improved.
[0022] 2. In this utility model, when a lot of dust accumulates on the surface of the heat sink on the heat dissipation device, the sliding fixing bracket slides along the surface of the support frame with the assistance of the limiting wheel. While the fixing bracket slides, it drives the mounting plate to slide. While the mounting plate slides, it drives the cleaning sleeve to slide. During the sliding process of the cleaning sleeve, the cleaning sleeve removes the dust accumulated on the heat sink. By setting up the cleaning structure, it is convenient for staff to clean the dust on the heat sink, which improves the heat dissipation effect of the heat sink and allows the heat sink to dissipate heat better.

[0028] Reference Figure 1As shown, this utility model provides a technical solution: a filter cavity with a heat dissipation structure, including a filter body 1 and two heat sinks 201. The surface of the filter body 1 is provided with a heat dissipation device 2. By setting the heat dissipation device 2, the heat dissipation area of the filter can be increased, the heat dissipation effect of the filter can be improved, the internal components of the filter will not overheat, and the performance of the filter can be improved. The surfaces of the two heat sinks 201 are provided with a cleaning structure 3. By setting the cleaning structure 3, it is convenient for staff to clean the dust on the heat sinks 201, improving the heat dissipation effect of the heat sinks 201, and making the heat sinks 201 replaceable for heat dissipation.
[0029] The specific setup and function of its heat dissipation device 2 and cleaning structure 3 will be explained below.
[0030] Reference Figure 2 As shown in this embodiment: the heat dissipation device 2 includes two heat sinks 201, the surfaces of which are slidably connected to the filter body 1. Two square plates 209 are fixedly installed on the surfaces of the two heat sinks 201. A positioning rod 203 is fixedly inserted inside the heat sink 201. A rotating plate 204 is rotatably sleeved on the arc surface of the positioning rod 203. A limiting groove 211 is formed on the surface of the rotating plate 204. Two pins 207 are fixedly installed on the surface of the filter body 1. The surface of the pins 207 abuts against the inner wall of the limiting groove 211. An elastic sleeve 208 is fixedly sleeved on the surface of the pins 207. The surface of the elastic sleeve 208 abuts against the rotating plate 204. An elastic pad 206 is fixedly installed on the surface of the filter body 1. The surface of the elastic pad 206 abuts against the two rotating plates 204. The elastic pad 206 presses the two rotating plates 204 with elastic force, thereby achieving the effect of assisting in fixing the rotating plates 204. A clamping plate 210 is fixedly mounted on the surface of the filter body 1. The surface of the clamping plate 210 is slidably connected to two square plates 209, allowing the staff to easily place the square plates 209 in the desired position. Iron plates 205 are fixedly mounted inside each of the two rotating plates 204, and magnets 202 are fixedly mounted on the surfaces of the two heat sinks 201. When the rotating plate 204 is rotated, after a certain angle, the iron plates 205 on the rotating plate 204 come into contact with the magnets 202. At this point, the rotating plate 204 cannot rotate due to the limiting effect of the iron plates 205 and the magnets 202, thus achieving the effect of restricting the rotation of the rotating plate 204.
[0031] Reference Figure 3 and Figure 4As shown, specifically, the cleaning structure 3 includes two support frames 34, with the surfaces of the two support frames 34 fixedly connected to each other. A fixing frame 33 is slidably fitted onto the surface of each support frame 34. Several mounting plates 32 are evenly fixedly mounted on the surface of each fixing frame 33, and a cleaning sleeve 31 is fixedly fitted onto the surface of each mounting plate 32. The surface of the cleaning sleeve 31 is slidably connected to the heat sink 201. Two limiting wheels 35 are rotatably connected inside each of the two fixing frames 33. The surfaces of the limiting wheels 35 are slidably connected to the support frame 34, allowing the fixing frame 33 to slide along the surface of the support frame 34 with the support of the limiting wheels 35, thus assisting in the sliding of the fixing frame 33. A pressing frame 36 is threadedly connected inside each of the two fixing frames 33. The surface of the pressing frame 36 abuts against the heat sink 201. Rotating the pressing frame 36 causes it to move closer to the heat sink 201 via the threads. After moving a certain distance, the surface of the pressing frame 36 presses against the heat sink 201, preventing the fixing frame 33 from sliding, thus limiting its sliding.
[0032] Working principle: When the heat dissipation effect of the filter is poor, two heat sinks 201 are placed on the filter, so that the two square plates 209 connected to the heat sinks 201 come into contact with the clamping plate 210. Then, the rotating plate 204 is rotated. After rotating a certain angle under the support of the positioning rod 203, the rotating plate 204 is fitted onto the pin 207. At this time, due to the compression of the elastic sleeve 208 and the elastic pad 206, the rotating plate 204 is fixed on the pin 207. At this time, the heat sinks 201 are also fixed on the filter. At this time, the heat sinks 201 can assist the filter in heat dissipation. By setting the heat dissipation device 2, the heat dissipation area of the filter can be increased, the heat dissipation effect of the filter can be improved, the internal components of the filter will not overheat, and the performance of the filter can be improved.
[0033] When a lot of dust accumulates on the surface of the heat sink 201 on the heat dissipation device 2, the extrusion frame 36 is rotated. The extrusion frame 36 moves away from the heat sink 201 by means of the thread. After the extrusion frame 36 moves a certain distance, the surface of the extrusion frame 36 no longer extrudes the heat sink 201. At this time, the fixing frame 33 loses its fixation. Then the fixing frame 33 slides. With the assistance of the limit wheel 35, the fixing frame 33 slides along the surface of the support frame 34. While the fixing frame 33 slides, it drives the mounting plate 32 to slide. While the mounting plate 32 slides, it drives the cleaning sleeve 31 to slide. During the sliding process, the cleaning sleeve 31 removes the dust accumulated on the heat sink 201. By setting the cleaning structure 3, it is convenient for staff to clean the dust on the heat sink 201, which improves the heat dissipation effect of the heat sink 201 and allows the heat sink 201 to dissipate heat better.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
