[0030] 4. Heat sink. DETAILED DESCRIPTION

[0031] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0032] The present invention provides a technical solution: an amplifier that is easy to dissipate heat and is applied to electronic equipment, such as Figure 1 and Figure 2 As shown, it includes an amplifier housing 1 and a heat dissipation component 3. A control system (i.e., a PLC controller) is provided in the amplifier and is in communication connection with the heat dissipation component 3 to realize intelligent control of heat dissipation. A circular groove 2 is provided on the top of the amplifier housing 1. A heat sink 4 is provided inside the amplifier housing 1. The amplifier generates a large amount of heat when working. The heat sink 4 can help to quickly conduct the heat to the surrounding air by increasing the surface area, thereby preventing the internal components of the amplifier from overheating. The shape and size of the heat sink 4 can be adjusted according to the design of the amplifier to meet different heat dissipation requirements.

[0033] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the heat dissipation component 3 is arranged above the amplifier housing 1, and the heat dissipation component 3 includes an exhaust member for exhausting hot air from the amplifier housing 1, and evenly exhausts the heat conducted to the air by the heat sink 4. The exhaust member includes a dual-axis motor 31, an exhaust fan 32, a gear 33 and a multi-claw tooth ring 34. The exhaust fan 32 and the gear 33 are respectively fixed to the two ends of the output shaft of the dual-axis motor 31, and the multi-claw tooth ring 34 is fixed to the top of the inner wall of the amplifier housing 1. The gear 33 is located on the inner side of the multi-claw tooth ring 34, and the tooth surfaces of the gear 33 and the multi-claw tooth ring 34 are meshed with each other. A temperature sensor can be added to the top of the inner wall of the amplifier housing 1, and the temperature sensor is used to monitor the temperature inside the amplifier housing 1 in real time, and the data is transmitted to the output shaft of the amplifier housing 1. The temperature is transmitted to the control system, and the control system sets one or more temperature thresholds (such as normal temperature, various levels of temperature for starting the heat dissipation intensity, etc.). The control system compares the real-time temperature obtained by the temperature sensor with the set threshold. When the temperature is lower than the set value, it is within the safety range. The dual-axis motor 31 and the exhaust fan 32 can remain in the off state to save energy. If the temperature exceeds the set safety threshold, the control system will send a signal to start the dual-axis motor 31, and change the speed of the dual-axis motor 31 according to the set various levels of temperature for starting the heat dissipation intensity, increase air flow, and accelerate the heat dissipation process. When the exhaust fan 32 is working, the temperature sensor still monitors the temperature in real time to ensure that the exhaust fan 32 is shut down or the speed is adjusted at the appropriate time.

[0034] like Figure 1-7As shown, the heat dissipation component 3 also includes a dust blocking member, which is arranged inside the circular groove 2. The dust blocking member is used to intercept dust and mosquitoes in the air to prevent dust from scattering through the ventilation groove 37 and accumulating on the components inside the amplifier and the heat sink 4 to affect the heat dissipation effect. The dust blocking member includes a disc hollow shell 35 that rotates inside the circular groove 2. A placement groove 36 is provided above the disc hollow shell 35. The filter screen 314 pushed out of the placement groove 36 is the filter screen 314 that needs to be cleaned. The filter screen 314 in the placement groove 36 can be easily taken out, cleaned and then put back. A ventilation groove 37 is provided inside the disc hollow shell 35. The ventilation groove 37 runs through the disc hollow shell 35 and is the main channel for the exhaust fan 32 to exhaust hot air. The top and bottom of the inner wall of the disc hollow shell 35 are provided with the A sealing groove 38 is provided, and a second sealing groove 39 is provided on the inner surface of the disc hollow shell 35. A filter frame 310 is rotated inside the disc hollow shell 35. The filter frame 310 is circular and has multiple through grooves in the middle to ensure that hot air can pass through. First sealing rings 311 are fixed above and below the filter frame 310. The two first sealing rings 311 are respectively clamped in the inside of the two first sealing grooves 38. A second sealing ring 312 is fixed on the outer surface of the filter frame 310. The second sealing ring 312 is clamped in the inside of the second sealing groove 39. Multiple filter grooves 313 are provided above the filter frame 310. Filters 314 are provided inside the multiple filter grooves 313. Two paddles are fixed above the filter 314. The setting of the paddles facilitates the application of a force point for upward extraction to the filter 314.

[0035] like Figure 1-7 As shown, a connecting arm 315 is fixed below the disc hollow shell 35, and the connecting arm 315 is located below the ventilation slot 37. The dual-axis motor 31 is fixedly installed at one end of the connecting arm 315, so that the exhaust fan 32 corresponds to the ventilation slot 37, ensuring that the hot air can be discharged along the exhaust direction, and the dual-axis motor 31 will drive the disc hollow shell 35 to rotate with the meshing of the gear 33 and the multi-claw tooth ring 34 and the rotation connection of the disc hollow shell 35, thereby making the exhaust fan 32 continuously rotate in the amplifier housing 1. When rotating, the exhaust fan 32 will exhaust air from different positions in the amplifier housing 1. Only one exhaust fan 32 is needed to achieve sufficient and uniform heat dissipation, effectively reduce the power consumption during heat dissipation, and achieve low-energy heat dissipation.

[0036] like Figure 1-7As shown, the heat dissipation component 3 also includes a screen changing component, which is used to automatically monitor whether the filter 314 is blocked and replace the blocked filter 314, timely replace the blocked filter 314 located at the ventilation slot 37, and replace the clean filter 314 to the position of the ventilation slot 37 to prevent the mesh from being blocked and affecting the efficiency of hot air discharge. The screen changing component includes a wind speed sensor 316 and a motor 317. The wind speed sensor 316 and the motor 317 are both connected to each other through existing technology and control system communication, and a threshold value is set in the control system (i.e., the maximum value to keep the motor 317 turned on and the minimum value to control the motor 317 to turn on). The wind speed sensor 316 can continuously monitor the airflow at the filter 314, and when an abnormality is detected When the air flow rate drops to the minimum value, a signal is generated. The control system receives the signal from the wind speed sensor 316 and instructs the motor 317 to start if it confirms that the filter 314 needs to be cleaned or replaced. The wind speed sensor 316 is fixed above the hollow shell 35 of the disc and is located at the edge of the ventilation slot 37. The motor 317 is fixed inside the hollow shell 35 of the disc and one end of the output shaft of the motor 317 is fixed below the filter frame 310. After the motor 317 is turned on by the control system, the filter frame 310 is rotated to a set angle and the filter 314 located at the ventilation slot 37 is transferred to the placement slot 36. At this time, another clean filter 314 is transferred to the ventilation slot 37 for continued use.

[0037] like Figure 1-7 As shown, a slot 318 is provided at the top of the inner wall of the disc hollow shell 35, and a plurality of inclined fixing blocks 319 are fixed above the filter frame 310. The plurality of inclined fixing blocks 319 are all located inside the slot 318. When the filter frame 310 rotates, the rotation tracks of the plurality of inclined fixing blocks 319 are carried out inside the slot 318. The inclined fixing blocks 319 block the slot 318 to prevent external dust and mosquitoes from entering the disc hollow shell 35 and making the unused filter 314 dirty. A mounting shell 320 is fixed on the inner side of the placement and retrieval slot 36. The mounting shell 320 is mounted and fixed above the corresponding position of the slot 318. An alarm 321 is fixed above the mounting shell 320. The alarm 321 is an audible and visual alarm. When the alarm 321 sounds, it indicates that there is a The filter screen 314 is pushed out of the hollow shell 35 of the disc, an opening button 322 is fixed on the top of the inner wall of the mounting shell 320, a fixing plate 323 is fixed inside the mounting shell 320, a sliding rod 324 is slid inside the fixing plate 323, a pressing head 325 is fixed at one end of the sliding rod 324, the pressing head 325 is close to the opening button 322 and is located above the fixing plate 323, an inclined block 326 is fixed at the other end of the sliding rod 324, a spring 327 is sleeved on the outside of the sliding rod 324, the spring 327 is located below the fixing plate 323, the inclined block 326 extends to the bottom of the mounting shell 320, when the spring 327 is in its original state and length, the inclined block 326 is located below the mounting shell 320, and the pressing head 325 is located above the fixing plate 323.

[0038] When in use, the heat sink 4 conducts the heat generated by the components of the amplifier when in use to the air in the amplifier housing 1, and the dual-axis motor 31 drives the exhaust fan 32 to exhaust the hot air in the amplifier housing 1. At the same time, the gear 33 is driven to rotate by the dual-axis motor 31, and when the gear 33 rotates, it realizes self-rotation and turnover around the inner side of the multi-claw tooth ring 34 through the meshing teeth and the connecting arm 315 supporting the dual-axis motor 31, thereby driving the connecting arm 315, the exhaust fan 32 and the hollow disc shell 35 to rotate continuously, ensuring that while exhausting the air, the exhaust fan 32 can always maintain a corresponding position with the ventilation slot 37, so as to maintain air exhaust and circulation. When rotating, the exhaust fan 32 will exhaust air from different positions in the amplifier housing 1. Only one exhaust fan 32 is needed to achieve sufficient and uniform heat dissipation, effectively reducing the power consumption during heat dissipation, and realizing low-energy heat dissipation.

[0039] When the filter 314 at the ventilation slot 37 is used for a long time, the scattered dust will block the filter holes of the filter 314. Once the filter holes are blocked, the exhaust fan 32 will be hindered to discharge hot air, which makes the heat dissipation more laborious, and the heat dissipation efficiency and effect are greatly reduced. It will also increase the power consumption of the dual-axis motor 31. The air flow rate of the filter 314 at the ventilation slot 37 is monitored in real time through the wind speed sensor 316. If it is detected that the gas flow rate is reduced to the minimum value, the control system will instruct the motor 317 to start, and the motor 317 will drive the filter frame 31 0 rotates, and the filter 314 located at the ventilation slot 37 is transferred to the discharge slot 36. At this time, another clean filter 314 is transferred to the ventilation slot 37. Every time the wind speed is detected to be reduced to the minimum value, the motor 317 will transfer a filter 314 to the discharge slot 36 until a clean filter 314 is transferred to the ventilation slot 37, so that the air flow rate of the exhaust fan 32 when exhausting is restored to a normal value. The motor 317 is in a closed state, so that the blocked filter 314 can be automatically and timely replaced to prevent the filter 314 from being blocked and affecting the heat dissipation effect.

[0040] When the filter frame 310 is rotated by the motor 317, the inclined fixing block 319 on the filter frame 310 will rotate accordingly. When the filter 314 rotates to the placement slot 36, the inclined fixing block 319 set at one edge of the filter 314 will slide over the inclined surface of the inclined block 326, and the inclined block 326 will be pushed into the mounting shell 320 by the inclined fixing block 319. During the upward movement, the spring 327 is squeezed and the slide bar 324 is driven to move upward. When the slide bar 324 moves upward, the pressing head 325 is pushed upward, and the pressing head 325 presses the opening button 322 to turn on the alarm 321, reminding the surrounding personnel that the filter 314 that needs to be cleaned is pushed out and can be taken down for cleaning at any time. After cleaning, it can be put back into the filter slot 313 and wait for the next use. If you forget to clean the filter 314 for a while, there are also a few extra filters 314 for adjustment.
