Description

Technical Field

[0001] The present invention relates to the technical field of generator set alarm devices, and in particular to a fault and abnormality alarm device for a generator set. Background Art

[0002] A generator set is a device that converts other forms of energy into electrical energy through power devices such as engines. It is mainly composed of an engine, a generator and a control system, and can provide power support for industrial manufacturing, home life and other scenarios. The fault abnormality alarm of a generator set usually refers to the use of sensors to monitor the key parameters of the generator set in real time during operation. When the parameters exceed the normal range, the control system will trigger the alarm mechanism and notify the operator through sound and light, display prompts, remote signals or Internet platforms to avoid excessive damage to the generator set and ensure the safe and stable operation of the generator set.

[0003] However, the generator sets with fault abnormality alarm function still have the following problems: First, the alarm device in the generator set lacks an alarm mechanism that is comparable to the sensor monitoring alarm method. The current sensor monitoring alarm method may have false alarms and fail to alarm normally and in time, which makes it impossible for the generator set to issue multiple signal alarms in time when a fault occurs, which in turn affects the reliability of the generator set alarm system; and when the generator set is overheated and vibrates abnormally, it is impossible to issue targeted alarms based on the source of the fault. For example, when the generator set is overheated, the staff should immediately take corresponding shock absorption or fire extinguishing cooling measures to avoid serious damage to the generator set; and the alarm device is difficult to adaptively notify the staff according to the severity of the generator set fault, so that the staff cannot judge the fault type and severity level in time, and thus it is difficult for the staff to take effective emergency repair measures in time; secondly, the heat dissipation mechanism set in the generator set box usually needs to have a protective function, so the heat dissipation and ventilation effect is relatively limited, and when the generator set overheats during operation, it is difficult to quickly adjust its heat dissipation and ventilation volume, resulting in further damage to the generator set. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a fault abnormality alarm device for a generator set, which can effectively solve the problem that the alarm device in the generator set in the prior art lacks an alarm mechanism that is corresponding to the sensor monitoring alarm method, making it impossible for the generator set to promptly issue multiple signal alarms when a fault abnormality occurs, thereby affecting the reliability of the generator set alarm system, and the staff cannot promptly judge the fault type and the severity level of the fault, making it difficult for the staff to take effective emergency repair measures according to the fault type in a timely manner, and the generator set is difficult to quickly adjust its heat dissipation ventilation volume when overheating, resulting in further damage to the generator set.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides a fault abnormality alarm device for a generator set, comprising: The generator set body includes a generator set and a box body.

[0006] Furthermore, the alarm trigger component includes two limit guide rails fixedly connected to the inner wall of the support frame, and a lifting support plate is slidably connected between the two limit guide rails. A No. 1 touch pressure switch and a No. 2 touch pressure switch are fixedly installed on the upper end surface of the lifting support plate.

[0007] Furthermore, the graded sound alarm component includes a sound alarm fixedly mounted on the upper end face of the box body, the sound alarm is electrically connected to the No. 1 touch pressure switch, the No. 2 touch pressure switch, and the PLC controller, the upper end face of the box body is fixedly connected to two shaft seats, the two shaft seats are evenly distributed on both sides of the sound alarm, the upper ends of the two shaft seats are rotatably connected to a rotating shaft, a spiral spring is fixedly connected between the end of the rotating shaft and the shaft seat, the outer peripheral walls of the two rotating shafts are fixedly connected to a hollow speaker frame, two fan-shaped elastic plates are slidably connected between the two hollow speaker frames, the upper ends of the two hollow speaker frames are fixedly connected to an arc-shaped electromagnet, and the two arc-shaped electromagnets are in a state of repulsion with the same poles when energized.

[0008] Furthermore, the graded sound alarm component also includes a support frame fixedly connected to the lower position of the inner wall of the support frame, a number of support springs are fixedly connected between the support frame and the lifting plate, a sliding resistance rod is fixedly connected to the lower end surface of the lifting plate, a through hole is opened in the middle of the support frame, the sliding resistance rod is slidably engaged with the through hole, and a damping slide is slidably connected to the outer peripheral wall of the sliding resistance rod.

[0009] Furthermore, the sliding resistor rod and the damping slider constitute a sliding rheostat, and the sliding rheostat, two arc-shaped electromagnets and an external power supply constitute a closed series circuit. When the damping slider moves toward the upper end of the sliding resistor rod, the resistance value of the sliding rheostat in the closed series circuit composed of the sliding resistor rod, the damping slider, two arc-shaped electromagnets and the external power supply increases.

[0013] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention provides a classification alarm component. When the generator set overheats or vibrates abnormally, the central hammer connecting rod will move down to contact and squeeze the No. 1 touch-pressure switch due to abnormal temperature, or the lateral hammer connecting rod will swing to contact and squeeze the No. 2 touch-pressure switch due to abnormal vibration, so that the dual-color alarm light and the sound alarm start to receive signals and continue to give sound and light signal alarms. At the same time, the trigger signal generated by the No. 1 touch-pressure switch can make the dual-color alarm light display red, indicating that the generator set is overheated, and the trigger signal generated by the No. 2 touch-pressure switch will make the dual-color alarm light display yellow, indicating that the generator set is vibrating abnormally, so that the dual-color alarm light can display different alarm colors according to different fault sources, so that the staff can judge the fault type in time and take effective emergency repair measures.

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: Refer to Figures 1 to 9 A fault abnormality alarm device for a generator set comprises: a generator set body 1, the generator set body 1 comprises a generator set and a box body 2, the generator set is arranged inside the box body 2, and a classification alarm component 3 is fixedly connected to the top of the box body 2; the classification alarm component 3 comprises a support frame 31 fixedly connected to the top of the box body 2, a two-color alarm light 32 is fixedly installed on the upper end surface of the support frame 31, a universal joint 33 is fixedly connected to the inner top surface of the support frame 31, a swing bracket 34 is fixedly connected to the lower end surface of the swing bracket 34, a piston cylinder 35 and a plurality of slide rails 36 are fixedly connected to the lower end surface of the swing bracket 34, a control piston 37 is sealingly and slidably connected to the inner wall of the piston cylinder 35, a liquid storage cavity is formed between the control piston 37, the inner wall of the piston cylinder 35 and the inner top surface of the piston cylinder 35, the liquid storage cavity is filled with a thermal expansion and contraction medium, and the lower end surface of the control piston 37 is fixedly connected to a center hammer connecting rod 38; The inner sides of the plurality of slide rails 36 are slidably connected to lifting blocks 39, the lower end surfaces of the plurality of lifting blocks 39 are fixedly connected to lateral hammer head connecting rods 310, and tension springs 311 are fixedly connected between the upper end surfaces of the plurality of lifting blocks 39 and the lower end surface of the swing bracket 34; An alarm trigger component 4 is fixedly connected to the inner wall of the support frame 31. The alarm trigger component 4 includes two limit guide rails 41 fixedly connected to the inner wall of the support frame 31. A lifting plate 42 is slidably connected between the two limit guide rails 41. A No. 1 touch-pressure switch 43 and a No. 2 touch-pressure switch 44 are fixedly installed on the upper end surface of the lifting plate 42. The lower end of the central hammer head connecting rod 38 and the lower end of the lateral hammer head connecting rod 310 selectively contact and squeeze with the No. 1 touch-pressure switch 43 and the No. 2 touch-pressure switch 44 respectively. A monostable trigger 45 and a PLC controller 46 are fixedly installed on the outer wall of the support frame 31. The No. 1 touch-pressure switch 43, the No. 2 touch-pressure switch 44, the two-color alarm light 32, the monostable trigger 45 and the PLC controller 46 are electrically connected; When the temperature inside the housing 2 rises, the thermal expansion and contraction medium in the piston cylinder 35 expands in volume due to the thermal expansion and contraction principle. The pressure in the liquid storage chamber of the piston cylinder 35 increases, pushing the control piston 37 downward to perform a sealing sliding motion. The central hammer connecting rod 38 also moves downward and eventually contacts and squeezes the No. 1 touch-pressure switch 43. Specifically, the thermal expansion and contraction medium uses silicone oil, which has a boiling point higher than the upper limit of the normal operating temperature of the generator set and has insulation properties; When the box body 2 vibrates abnormally, the swing bracket 34 will swing flexibly in three-dimensional space, causing the side hammer connecting rods 310 to swing and contact and squeeze the second touch-press switch 44; When the generator set is operating normally, the lifting plate 42 is in the initial position. When the central hammer connecting rod 38 moves down to contact and squeeze the No. 1 touch-pressure switch 43 due to abnormal temperature, or when the lateral hammer connecting rod 310 swings to contact and squeeze the No. 2 touch-pressure switch 44 due to abnormal vibration, the corresponding No. 1 touch-pressure switch 43 or No. 2 touch-pressure switch 44 is triggered and generates an electrical signal, so that the two-color alarm light 32 and the sound alarm 51 start to receive signals and continue to sound and light signal alarms. At the same time, the trigger signal generated by the No. 1 touch-pressure switch 43 can make the two-color alarm light 32 display red, indicating that the generator set is overheated, and the trigger signal generated by the No. 2 touch-pressure switch 44 can make the two-color alarm light 32 display yellow, indicating that the generator set is vibrating abnormally, so that the two-color alarm light 32 can display different alarm colors according to different fault sources, so that the staff can promptly determine the fault type and take effective emergency repair measures. At the same time, it can be compared with the sensor monitoring alarm mode to realize the dual insurance signal alarm of the generator set, which is beneficial to improving the reliability of the generator set alarm system; Specifically, the No. 1 touch-pressure switch 43 is circular in structure and is located at the center of the upper end surface of the lifting plate 42, and the No. 2 touch-pressure switch 44 is annular in structure and is located at the edge of the upper end surface of the lifting plate 42. After receiving the trigger signal generated by the No. 1 touch-pressure switch 43 being triggered, the No. 2 touch-pressure switch 44 being triggered, or the No. 1 touch-pressure switch 43 and the No. 2 touch-pressure switch 44 being triggered synchronously, the monostable trigger 45 can flip the trigger signal from a steady state to a temporary steady state and output a high-level signal that lasts for a certain period of time, that is, when the No. 1 touch-pressure switch 43 or the No. 2 touch-pressure switch 44 is subsequently contacted and squeezed again, it will still be in the triggered state, so as to ensure the continuous alarm of the two-color alarm light 32 and the sound alarm 51; Specifically, the two-color alarm light 32 is provided with a red light group and a yellow light group, and the PLC controller 46 can simultaneously monitor the trigger signal status of the No. 1 touch-pressure switch 43 and the No. 2 touch-pressure switch 44. When the No. 1 touch-pressure switch 43 generates a trigger signal, the PLC controller 46 controls the red light group of the two-color alarm light 32 to display accordingly. When the No. 2 touch-pressure switch 44 generates a trigger signal, the PLC controller 46 controls the yellow light group of the two-color alarm light 32 to display accordingly. When the No. 1 touch-pressure switch 43 generates a trigger signal or the No. 2 touch-pressure switch 44 generates a trigger signal or both the No. 1 touch-pressure switch 43 and the No. 2 touch-pressure switch 44 generate trigger signals, the PLC controller 46 controls the two-color alarm light 32 to display only the red light group or only the yellow light group or both the red light group and the yellow light group. Specifically, when the PLC controller 46 detects the trigger signal, it will synchronously transmit a start signal to the sound alarm 51, causing the sound alarm 51 to generate a sound signal alarm.

[0020] The upper end surface of the box body 2 is fixedly mounted with a graded sound alarm component 5, which includes a sound alarm 51 fixedly mounted on the upper end surface of the box body 2. The sound alarm 51 is electrically connected to the No. 1 touch pressure switch 43, the No. 2 touch pressure switch 44, and the PLC controller 46. The upper end surface of the box body 2 is fixedly connected with two shaft seats 52, which are evenly distributed on both sides of the sound alarm 51. The upper ends of the two shaft seats 52 are rotatably connected with a rotating shaft 53, and the end of the rotating shaft 53 is connected to the shaft seat 52. A volute spring 54 is fixedly connected, and the outer peripheral walls of the two rotating shafts 53 are fixedly connected to hollow speaker frames 55. Two fan-shaped elastic plates 56 are slidably connected between the two hollow speaker frames 55. An annular sound insulation cotton 8 is fixedly connected to the outer peripheral wall of the sound alarm 51. The lower ends of the two hollow speaker frames 55 and the two fan-shaped elastic plates 56 are squeezed and matched with the annular sound insulation cotton 8. The upper ends of the two hollow speaker frames 55 are fixedly connected to arc-shaped electromagnets 57. The two arc-shaped electromagnets 57 are in a state of repulsion with the same poles when energized; The graded sound alarm component 5 also includes a support frame 58 fixedly connected to the lower position of the inner wall of the support frame 31, a number of support springs 59 are fixedly connected between the support frame 58 and the lifting plate 42, a sliding resistor rod 510 is fixedly connected to the lower end surface of the lifting plate 42, a through hole is opened in the middle of the support frame 58, the sliding resistor rod 510 slides with the through hole, and a damping slider 511 is slidably connected to the outer peripheral wall of the sliding resistor rod 510, the sliding resistor rod 510 and the damping slider 511 constitute a sliding rheostat, and the sliding rheostat, two arc-shaped electromagnets 57 and an external power supply constitute a closed series circuit. It should be noted that the two arc-shaped electromagnets 57 are always in an energized state to ensure a timely response to the sound signal alarm, and when the damping slider 511 moves toward the upper end of the sliding resistor rod 510, the resistance value of the sliding rheostat in the closed series circuit composed of the sliding resistor rod 510, the damping slider 511, the two arc-shaped electromagnets 57 and the external power supply increases; When the No. 1 touch-pressure switch 43 or the No. 2 touch-pressure switch 44 is triggered, the lifting plate 42 will move downward due to the pressure of the central hammer head connecting rod 38 or the lateral hammer head connecting rod 310, so that the damping slide 511 moves toward the upper end of the sliding resistor rod 510. That is, when the sliding resistor rod 510 moves downward and the damping slide 511 moves upward relatively, the longer the lifting plate 42 moves downward, the more serious the overheating or abnormal vibration fault is, the greater the resistance value of the sliding rheostat connected to the circuit, and the connected current of the two arc-shaped electromagnets 57 is reduced. The smaller the arc-shaped electromagnets 57, the smaller the magnetic repulsion between them. This in turn reduces the size of the amplifying structure composed of the two hollow speaker frames 55 and the two fan-shaped elastic plates 56 and increases the internal vibration frequency, making the alarm sound of the sound alarm 51 sharper, indicating that the severity of the overheating or abnormal vibration of the box 2 is higher, thereby realizing a graded sound signal alarm, which can adaptively notify the staff according to the severity of the fault of the generator set, so that the staff can promptly judge the severity of the fault and take effective emergency repair measures. Specifically, the damping slider 511 is made of a rubber-metal composite material. The rubber provides friction damping, while the metal provides electrical conductivity. Due to the friction damping effect of the rubber, the damping slider 511 stays on the sliding resistor rod 510 when it moves upward relative to the sliding resistor rod 510, thereby maintaining the stability of the resistance change of the sliding resistor composed of the sliding resistor rod 510 and the damping slider 511. Specifically, the volute spring 54 is pre-tightened and has an initial tensile force, so that the volute spring 54 can continuously and elastically stretch the rotating shaft 53 to rotate, thereby making the hollow speaker frame 55 always tend to move closer to the sound alarm 51; Specifically, the annular sound insulation cotton 8 can be squeezed and matched with the two hollow speaker frames 55 and the lower ends of the two fan-shaped elastic plates 56 to focus the alarm sound emitted by the sound alarm 51; Specifically, when the lifting plate 42 moves downward and approaches the support frame 58, the support spring 59 is in a compressed state and accumulates a certain elastic force. When the lifting plate 42 is no longer contacted and squeezed by the central hammer head link 38 or the lateral hammer head link 310, several support springs 59 can elastically support the lifting plate 42, so that the lifting plate 42 can automatically move up and reset.

[0021] The two opposite side walls of the box body 2 are provided with heat dissipation windows 6, and the inner side of the heat dissipation window 6 is rotatably connected to an adjustable heat dissipation component 7, which includes a plurality of rotating rods 71 rotatably connected to the inner side of the heat dissipation window 6, and the outer peripheral walls of the plurality of rotating rods 71 are fixedly connected to heat dissipation fins 72, and the ends of the plurality of heat dissipation fins 72 located in the box body 2 are rotatably connected through a plurality of rectangular connecting rods 73. A rotating seat 74 is fixedly connected to the lower position of the inner wall of the box body 2, and an electric push rod 75 is rotatably connected to the rotating seat 74. The telescopic end of the electric push rod 75 is rotatably connected to the heat dissipation fin 72 located at the bottom. The adjustable heat dissipation component 7 also includes a displacement sensor 76 fixedly mounted on the inner wall of the support frame 31. The displacement sensor 76 is used to monitor the displacement of the center hammer connecting rod 38 relative to the piston cylinder 35 in real time. The displacement sensor 76 and the electric push rod 75 are electrically connected to the PLC controller 46; The displacement sensor 76 can monitor the displacement of the center hammer connecting rod 38 relative to the piston cylinder 35 in real time. The displacement of the center hammer connecting rod 38 relative to the piston cylinder 35 can reflect the degree of abnormal temperature inside the box body 2. When the center hammer connecting rod 38 moves downward due to temperature increase, the telescopic end of the electric push rod 75 can be controlled by the PLC controller 46 to extend and retract. The plurality of heat dissipation fins 72 will rotate to a corresponding angle to automatically increase the ventilation volume of the heat dissipation window 6, thereby realizing adaptive heat dissipation adjustment of the heat dissipation window 6 to the box body 2, ensuring that the generator set can effectively dissipate heat in the event of an overheating fault, thereby avoiding further damage to the generator set due to overheating. Specifically, the displacement sensor 76 is an image recognition type non-contact displacement sensor, and the displacement sensor 76 is located at a -45° direction of the central hammer head connecting rod 38, so that when the lateral hammer head connecting rods 310 swing, there will be no motion interference with the displacement sensor 76; Specifically, the two ends of the rectangular connecting rod 73 are rotatably connected to the ends of adjacent heat dissipation fins 72 through hinge shafts to form a parallelogram linkage mechanism. When the electric push rod 75 pushes the lowest heat dissipation fin 72 to rotate, the rigid transmission of the rectangular connecting rod 73 drives all the heat dissipation fins 72 to rotate synchronously at the same angle, ensuring that the ventilation volume of the heat dissipation window 6 is evenly adjusted.

[0022] Specifically, when the electric push rod 75 is extended or retracted, it pushes the bottom heat dissipation fin 72 to rotate, and through the transmission action of the rectangular connecting rod 73, it drives the other heat dissipation fins 72 to rotate synchronously, so as to change the inclination angle of the heat dissipation fins 72, thereby adjusting the ventilation volume of the heat dissipation window 6. The larger the inclination angle of the heat dissipation fins 72, the greater the ventilation volume of the heat dissipation window 6, and the better the heat dissipation effect of the box body 2; The working principle of the present invention is as follows: When the temperature inside the box 2 rises due to an abnormal fault in the generator set, such as overheating or short circuit of a component, the thermal expansion and contraction medium in the piston cylinder 35 expands in volume due to the thermal expansion and contraction principle. The pressure in the liquid storage chamber of the piston cylinder 35 increases accordingly, pushing the control piston 37 downward to perform a sealing sliding motion. The center hammer connecting rod 38 fixedly connected to the lower end surface of the control piston 37 also moves downward and eventually contacts and squeezes the No. 1 touch-press switch 43. If abnormal vibration occurs during the operation of the generator set, the box body 2 will synchronously generate abnormal vibration and transmit it to the support frame 31. Since the swing bracket 34 is connected to the top surface of the support frame 31 through the universal joint 33, the universal joint 33 can make the swing bracket 34 flexibly swing in three-dimensional space to adapt to the vibration of the box body 2 in different directions. Under the vibration of the support frame 31, the swing bracket 34 will shake synchronously and cause the multiple slide rails 36 to swing synchronously. When the slide rail 36 swings, the lifting block 39 on the inside thereof will overcome the tension of the tension spring 311 under the action of the inertial force of the vibration and slide along the slide rail 36, causing the multiple lateral hammer connecting rods 310 to swing accordingly. When the abnormal vibration amplitude of the generator set reaches a certain level, the lower end of the lateral hammer connecting rod 310 will contact and squeeze the No. 2 touch-pressure switch 44. When the generator set is in normal operation, the lifting plate 42 is in the initial position, and the No. 1 touch-pressure switch 43 and the No. 2 touch-pressure switch 44 are not triggered. When the central hammer connecting rod 38 moves down to contact and squeeze the No. 1 touch-pressure switch 43 due to abnormal temperature, or when the lateral hammer connecting rod 310 swings to contact and squeeze the No. 2 touch-pressure switch 44 due to abnormal vibration, the corresponding No. 1 touch-pressure switch 43 or No. 2 touch-pressure switch 44 is triggered and generates an electrical signal, so that the two-color alarm light 32 and the sound alarm 51 start to receive signals and continue to sound and light signal alarms. At the same time, the two-color alarm light 32 can display two alarm colors, red and yellow. The trigger signal generated by the No. 1 touch-pressure switch 43 can make the two-color alarm light 32 display red, indicating that the generator set is overheated, and the trigger signal generated by the No. 2 touch-pressure switch 44 can make the two-color alarm light 32 display yellow, indicating that the generator set is abnormally vibrating, so that the two-color alarm light 32 can display different alarm colors according to different fault sources; The trigger signal of the No. 1 touch-pressure switch 43 or the No. 2 touch-pressure switch 44 can be synchronously transmitted to the sound alarm 51, causing it to emit a basic alarm sound. When the No. 1 touch-pressure switch 43 or the No. 2 touch-pressure switch 44 is triggered, the lifting plate 42 will move downward due to the squeezing of the central hammer head connecting rod 38 or the lateral hammer head connecting rod 310. During this process, the sliding resistance rod 510 will synchronously pass through the through hole in the middle of the support frame 58 and drive the damping slide 511 to move downward, and the support frame 58 will hinder the downward movement of the damping slide 511. When the damping slide 511 moves toward the upper end of the sliding resistance rod 510, the longer the downward movement distance of the lifting plate 42 is, the more serious the overheating or abnormal vibration fault is. The higher the degree, the greater the resistance value of the sliding rheostat connected to the circuit. According to Ohm's law, the current in the circuit will decrease, that is, the current connected to the two arc-shaped electromagnets 57 will decrease, so that the magnetic repulsion between the two arc-shaped electromagnets 57 will be smaller, and the two hollow speaker frames 55 and the two fan-shaped elastic plates 56 can form a trumpet-shaped sound amplification structure. When the magnetic repulsion between the two arc-shaped electromagnets 57 is smaller, the rotation angle of the two hollow speaker frames 55 is smaller, and the sound amplification structure composed of the two hollow speaker frames 55 and the two fan-shaped elastic plates 56 is reduced and its internal vibration frequency is increased, so that the alarm sound of the sound alarm 51 is sharper, indicating that the severity of the fault of overheating or abnormal vibration of the box 2 is higher; The displacement sensor 76 can monitor the displacement of the center hammer connecting rod 38 relative to the piston cylinder 35 in real time. The displacement of the center hammer connecting rod 38 relative to the piston cylinder 35 can reflect the degree of temperature abnormality inside the box body 2. When the center hammer connecting rod 38 moves down due to temperature increase, the displacement sensor 76 converts the displacement signal of the center hammer connecting rod 38 into an electrical signal and transmits it to the PLC controller 46. After processing the signal, the PLC controller 46 sends an instruction to the electric push rod 75 according to the preset control logic to control the extension amount of the telescopic end of the electric push rod 75. When the temperature abnormality inside the box body 2 is relatively mild, the PLC controller 46 can control the telescopic end of the electric push rod 75 to extend and retract slightly, and several heat dissipation fins 72 will rotate a small angle to moderately increase the ventilation volume of the heat dissipation window 6. When the temperature abnormality inside the box body 2 is serious, the PLC controller 46 will control the telescopic end of the electric push rod 75 to extend and retract significantly, and several heat dissipation fins 72 will rotate a large angle to significantly increase the ventilation volume of the heat dissipation window 6.
