Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to an airflow control device and electronic equipment. Background Technology

[0002] Electronic devices such as computers and air conditioners generate heat during operation. Overheating can lead to decreased performance or even damage. Cooling fans effectively reduce this heat, ensuring normal operation and extending the device's lifespan.

[0003] Existing technologies typically employ air cooling for heat dissipation. This involves setting up multiple exhaust fans to expel air from the enclosure, creating negative pressure inside the enclosure. This allows external air to enter through the intake module for heat dissipation. During this process, the airflow within the enclosure needs to be adjusted according to the internal temperature to ensure that the electronic components inside the enclosure are within a suitable temperature range.

[0004] Currently, airflow is adjusted by changing the speed of the exhaust fan itself. This not only generates a lot of noise, but also requires a certain feedback time during the speed adjustment process because it involves changing the motor, connecting parts, and other indirect structures to change the fan speed. This results in low conversion efficiency and unnecessary energy loss. Utility Model Content

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0048] The inventive concept of this application is as follows:

[0049] In the first aspect, this application provides an airflow control device in Embodiment 1. The airflow adjustment method adopted by the device is to change the area of ​​the opening 310 formed by the opening and closing component 300 on the support body 100 by moving the drive plate 200 between the first position and the second position, thereby changing the airflow through the opening 310. Compared with the prior art that controls the airflow by changing the power of the motor 410, this device directly controls the airflow itself, the adjustment effect is more direct, the conversion efficiency is improved, and the power loss generated by the motor 410 during adjustment is eliminated.

[0050] Secondly, in Embodiment 1, the structure between the opening and closing component 300, the drive plate 200 and the support body 100 is set. That is, through the linkage design of the drive plate 200 along the first position and the second position, the guide plate 320 in the opening and closing component 300 is used as the connecting component between the support body 100 and the drive plate 200 to realize the switching of the opening 310 between the first state and the second state.

[0051] Subsequently, in Embodiment 1, the connection method of the guide vane 320 between the support body 100 and the drive plate 200 was set to ensure that the torque can be effectively transmitted during the movement of the drive plate 200, thereby improving the reliability of the product.

[0052] Secondly, in Embodiment 2, this application provides an improved structure and a method for automatically adjusting the heat dissipation of the device on the electronic device, based on the heat generation of the electronic device. Through the electrical connection between the drive member 400 and the control member, the drive member 400 applies a reciprocating force to the drive plate 200 between a first position and a second position, while the control member controls the drive member 400 to adjust the distance between the support body 100 and the drive plate 200 according to the actual use of the electronic device.

[0053] Thirdly, in Embodiment 3, this application provides a method for integrating the device into an electronic device.

[0054] The following is a detailed description of the above-mentioned inventive concept:

[0055] Example 1

[0056] like Figure 1 As shown, this embodiment provides an airflow control device, including:

[0057] Supporting main body 100;

[0058] An opening and closing component 300 is provided on the support body 100; and the opening and closing component 300 is provided with an adjustable opening 310.

[0059] The drive plate 200 has a first position and a second position relative to the support body 100;

[0060] One end of the opening and closing component 300 is connected to the drive plate 200. When the drive plate 200 is in the first position, the opening 310 of the opening and closing component 300 is in the first state. When the drive plate 200 is in the second position, the opening 310 of the opening and closing component 300 is in the second state. The opening 310 in the first state and the second state are different in size.

[0061] Specifically, the support body 100 is located in the control area requiring heat dissipation. A fan or other power device is installed on the side of the support body 100 facing away from the control area. This power device provides a continuous and stable airflow to the support body 100 to enhance heat circulation within the control area. An opening / closing assembly 300 is provided on the support body 100, with an opening 310 for allowing airflow to enter the other side of the support body 100. By changing the size of the opening 310, the amount of airflow entering the control area can be adjusted. The control structure of the opening 310 is as follows:

[0062] One end of the opening and closing component 300 is connected to the drive plate 200. The drive plate 200 has a first position and a second position relative to the support body 100, and the drive plate 200 moves between the first position and the second position. When the drive plate 200 is in the first position, the opening 310 is in the first state. When the drive plate 200 gradually moves to the second position, the opening 310 gradually changes to the second state as the drive plate 200 moves. Since the opening 310 in the first state and the second state are different in size, the airflow through the opening 310 is changed, thereby achieving the adjustment of the airflow volume entering the control area.

[0063] It should be noted that the first and second positions need to be set according to the specific structure of the opening and closing component 300, such as... Figure 1 As shown, the opening and closing component 300 controls the airflow of the opening 310 by adjusting the angle at which the guide vane 320 is tilted outward. In this structure, the first and second positions are set in the same direction as the airflow and are positioned relative to the support body 100. Figure 5 As shown, the opening and closing component 300 uses a drive plate 200 to slide along the opening 310, thereby adjusting the air volume by increasing the ventilation area of ​​the opening 310. In this structure, the first position and the second position are set on the support body 100, which serves as the sliding trajectory of the drive plate 200 relative to the opening 310.

[0064] The following is a detailed description of the different linkage structures of the opening and closing component 300 and the drive plate 200 relative to the supporting body 100.

[0065] like Figure 1 As shown, when the opening / closing assembly 300 uses the guide vane 320 to control the ventilation area of ​​the opening 310, its structure is as follows:

[0066] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the opening and closing assembly 300 is provided with a guide plate 320 along the opening 310. The guide plate 320 includes a first connecting end 321, a guide body 323, and a second connecting end 322. The first connecting end 321 and the second connecting end 322 are respectively located at both ends of the guide body 323. The first connecting end 321 is rotatably connected to the support body 100, and the second connecting end 322 is connected to the drive plate 200.

[0067] When the drive plate 200 moves to the first position, the guide body 323 covers the opening 310 so that the opening 310 is in the first state;

[0068] When the drive plate 200 moves from the first position to the second position, the drive plate 200 drives the first connection end 321 to rotate through the second connection end 322 so that the opening 310 is in the second state.

[0069] A corresponding through hole is provided on the support body 100 at the connection position of the opening and closing component 300, serving as the prototype of the ventilation opening 310. By providing a guide plate 320 at the opening 310, a ventilation area controllable opening 310 structure is formed. The guide plate 320 consists of three main parts: a first connecting end 321, a guide body 323, and a second connecting end 322. The first connecting end 321 is rotatably connected to the support body 100, allowing the guide plate 320 to rotate around the connection point. The second connecting end 322 is connected to the drive plate 200, serving as the key point for the drive plate 200 to move the guide plate 320 when it moves. The guide body 323 is the main part of the guide plate 320, and its function is to cover or open the opening 310 in different states to adjust the airflow.

[0070] When the driver board 200 is in different positions, the following changes will occur:

[0071] When the drive plate 200 is in the first position, the flow guide body 323 is arranged to cover the opening 310 due to the position of the drive plate 200. At this time, the opening 310 is basically closed or has only a very small gap. This represents the first state of the opening 310, which is suitable for situations that require less ventilation.

[0072] When the drive plate 200 moves from the first position to the second position, it pulls the guide vane 320 through the second connecting end 322, causing the guide vane 320 to rotate around the first connecting end 321 (i.e., the rotatable connection point with the connecting rod of the support body 100). As a result, the guide body 323 gradually moves away from the opening 310, expanding the area of ​​the opening 310 and increasing the airflow, reaching the second state of the opening 310. This state is suitable for situations requiring greater ventilation to improve heat dissipation efficiency.

[0073] This design allows for highly flexible and precise control of airflow within electronic devices, improving response speed and conversion efficiency, reducing noise and energy loss, and better adapting to different heat dissipation needs. Furthermore, regulating airflow through direct mechanical operation rather than changing fan speed further simplifies the control system and may provide a faster and more direct temperature regulation response.

[0074] Furthermore, such as Figure 2 and Figure 3 As shown, the support body 100 includes a connecting bracket 120, the connecting bracket 120 includes a connecting rod 110, and the first connecting end 321 is rotatably connected to the connecting rod 110.

[0075] In this embodiment, the rotational connection between the first connecting end 321 and the support body 100 is provided by the connecting rod 110. The number of connecting rods 110 corresponds to the number of guide vanes 320. This connection method can be composed of the following two methods:

[0076] When there is only one guide vane 320, the connecting rod 110 is set to one side of the opening 310 through the connecting bracket 120. The guide body 323 is rotatably connected to the connecting rod 110 through the first connecting end 321 and can cover the opening 310. As the drive plate 200 moves from the first position to the second position, the drive plate 200 drives the first connecting end 321 to rotate through the connection with the second connecting end 322, thereby controlling the guide vane 320 body to be gradually opened.

[0077] Preferably, there can be multiple air guide vanes 320 and multiple connecting rods 110, which are connected longitudinally and transversely to allow multiple air guide vanes 320 to be arranged around the opening 310. In this structure, the multiple connecting rods 110 not only serve to rotatably connect with the air guide vanes 320, but also act as "joints" to a certain extent, enabling each air guide vane 320 to move in a coordinated manner to jointly complete the fine adjustment of the size and shape of the opening 310. That is, each air guide vane 320 can adjust its angle independently or collaboratively, thereby more accurately controlling the airflow and direction. This flexibility allows the system to respond quickly to different heat dissipation requirements, providing greater freedom and possibilities for optimizing the airflow inside electronic devices, and further improving the overall performance and service life of the equipment.

[0078] Furthermore, such as Figure 4 As shown, a groove 210 is provided at the position where the drive plate 200 is connected to the second connecting end 322; the second connecting end 322 is inserted into the groove 210 and moves along the groove 210;

[0079] The chute 210 is provided with a first end point and a second end point. When the drive plate 200 is in the first position, the second connection end 322 is located at the first end point, and the guide body 323 covers the opening 310 so that the opening and closing assembly 300 is in the first state.

[0080] When the drive board 200 moves from the first position to the second position, the second connection end 322 moves from the first end point to the second end point, so that the opening and closing component 300 is in the second state.

[0081] In this embodiment, the connection between the second connection end 322 and the drive plate 200 is provided with a corresponding groove 210 structure to make the movement of the guide vane 320 smoother and more accurate. Specifically:

[0082] When the drive plate 200 is in the first position, the second connection end 322 is located at the first end of the slide 210; at this time, the guide body 323 completely covers the opening 310, that is, the opening 310 is in a closed state, allowing very little or no airflow. At this time, the opening and closing assembly 300 is in the first state, which is suitable for situations requiring minimal ventilation.

[0083] When the drive plate 200 moves from the first position to the second position, the second connecting end 322 moves from the first end point to the second end point of the slide groove 210. This causes the guide body 323 to gradually move away from the opening 310, expanding the area of ​​the opening 310 and increasing airflow. When the second connecting end 322 reaches the second end point of the slide groove 210, the opening 310 reaches its maximum opening. At this time, the opening / closing assembly 300 is in the second state, suitable for situations requiring maximum ventilation to improve heat dissipation efficiency.

[0084] With the chute 210 in place, the second connecting end 322 of the guide vane 320 can move smoothly along the chute 210, thereby enabling continuous adjustment of the angle of the guide vane 320. This not only improves the smoothness of operation but also reduces mechanical wear and extends the service life of the equipment. Simultaneously, because the chute 210 has clearly defined first and second endpoints, the size of the opening 310 can be accurately adjusted by precisely controlling the position of the drive plate 200, ensuring optimal heat dissipation. Furthermore, this design allows for flexible adjustment of the opening 310 size according to actual needs, responding quickly to both slight temperature fluctuations and significant changes in heat dissipation requirements.

[0085] Furthermore, such as Figure 4 As shown, the end of the second connecting end 322 that contacts the slide groove 210 is provided with an abutment 324, which is used to restrict the second connecting end 322 from sliding out of the slide groove 210.

[0086] Specifically, in this embodiment, the abutment 324 can achieve its function by physical blocking, for example, by using protrusions, blocks or the like to fix it to the end of the second connecting end 322. When the second connecting end 322 reaches the end of the slide groove 210, the abutment 324 will touch the edge of the slide groove 210 and prevent further movement.

[0087] By providing the abutment 324, the movement range of the second connecting end 322 within the slide 210 can be limited, preventing it from sliding out of the slide 210 due to excessive movement. This ensures the integrity of the entire mechanical structure and prevents functional failure or equipment damage due to component detachment.

[0088] To further improve the movement accuracy of the driver board 200, the following improvements are made in this embodiment:

[0089] Furthermore, such as Figure 2 and Figure 3 As shown, a guide 130 is also provided between the drive plate 200 and the support body 100. The guide 130 is provided on the support body 100. The drive plate 200 is provided with a connection hole, and the drive plate 200 is connected to the guide 130 through the connection hole.

[0090] The guide member 130 is disposed on the support body 100, and the drive plate 200 is connected to the guide member 130 through the connecting hole thereon. The main function of the guide member 130 is to provide a precise moving path for the drive plate 200, ensuring that the drive plate 200 can only move in a preset direction without deviation or tilting.

[0091] The design of the guide component 130 significantly improves the accuracy and smoothness of the drive plate 200's movement, which is crucial for applications requiring precise adjustment of the opening 310 size to control airflow. Simultaneously, the guide component 130 provides additional mechanical support, increasing the overall system's stability and durability, and reducing the risk of mechanical failure due to prolonged use or external impacts.

[0092] In order to ensure that the airflow control of opening 310 is in a stable initial state, that is, when no additional force is applied, the drive plate 200 will automatically return to the first position, at which time the opening and closing component 300 is in the first state and the airflow guide body 323 covers the opening 310, the following improvements are made in this embodiment:

[0093] Furthermore, the elastic member 140 is disposed between the drive plate 200 and the support body 100, and the elastic member 140 is used to apply a force to the drive plate 200 to hold it in a first position.

[0094] The elastic component 140 can be configured with a return spring, damping component, or other components with a rebound function, so that the drive plate 200 always tends to rebound towards the first position. Through the elastic component 140, the drive plate 200 can reliably return to or maintain the first position even under changes in the external environment or equipment vibration, ensuring the overall stability and reliability of the equipment. Simultaneously, the elastic component 140 can absorb and buffer the impact force generated by the movement of the drive plate 200, protecting internal components from damage. Furthermore, when it is necessary to change the position of the drive plate 200, overcoming the resistance of the elastic component 140 helps the drive plate 200 move smoothly to the target position.

[0095] In summary, the guide component 130 and the elastic component 140 work together to ensure that the drive plate 200 can move smoothly and accurately along the predetermined trajectory; on the other hand, they also ensure that the system has good self-resetting ability and resistance to external interference, thus improving the stability of the device operation.

[0096] like Figure 5 As shown, when the opening and closing assembly 300 uses the drive plate 200 to slide along the opening 310, thereby controlling the ventilation area of ​​the opening 310, its structure is as follows:

[0097] The drive plate 200 includes a cover plate 330 and a slide rail 340. The slide rail 340 is located near the opening 310. The cover plate 330 is connected to the support body 100 via the slide rail 340 or a similar structure. By sliding along the slide rail 340, the ventilation area of ​​the opening 310 can be adjusted. This sliding connection allows the drive plate 200 to move along a preset path.

[0098] The sliding connection opening 310 on the driver board 200 is ideally suited for electronic devices requiring frequent airflow adjustments and efficient heat dissipation. It not only provides excellent adjustability but also simplifies the overall design, reduces manufacturing costs, and enhances system durability and responsiveness.

[0099] Example 2

[0100] Embodiment 1 provides a technical solution for adjusting the ventilation area of ​​the opening 310 and thus controlling the airflow by linking a drive plate 200 and an opening / closing component 300 disposed on the support body 100. In this solution, the drive plate 200 can be moved manually or controlled by an electronic device. This embodiment provides a control method for moving the drive plate 200 along a first position and a second position to achieve precise and effective automatic adjustment of the ventilation area of ​​the opening 310.

[0101] Specifically:

[0102] Furthermore, it also includes a drive member 400; the drive member 400 is connected between the support body 100 and the drive plate 200, and the drive member 400 is used to drive the drive plate 200 to move between a first position and a second position.

[0103] Specifically, the drive unit 400 can be a motor 410, a cylinder 430, or other types of actuators. By sending commands through the control system, the drive unit 400 can accurately position the drive plate 200 in the required position, ensuring that the size of the opening 310 meets the heat dissipation requirements.

[0104] The structural principle of the drive unit 400, which is controlled by motor 410, is as follows:

[0105] Furthermore, such as Figure 6 As shown, the drive unit 400 includes a motor 410 and a drive rod 420. One end of the drive rod 420 is connected to the output end of the motor 410, and the other end is connected to the drive plate 200.

[0106] When the drive plate 200 moves from the first position to the second position, the motor 410 drives the drive rod 420 to move, so that the drive rod 420 applies a thrust to the drive plate 200 toward the second position.

[0107] Specifically, the output end of the motor 410 is connected to one end of the drive rod 420, while the other end of the drive rod 420 is connected to the drive plate 200. Driven by the motor 410, the drive plate 200 smoothly slides from a first position to a second position along the path provided by the guide 130, or moves back to the first position. This linear movement directly changes the effective ventilation area of ​​the opening 310, thereby regulating the airflow through the device.

[0108] The technical advantages of this solution are as follows: Using a motor 410 and a drive rod 420 to control the movement of the drive plate 200 not only improves the operational flexibility and efficiency of the airflow control device, but also enhances its reliability and durability, making it suitable for various electronic devices requiring efficient heat dissipation management. This design allows users to flexibly adjust the ventilation volume according to actual needs, ensuring that the equipment maintains its optimal operating temperature under different working conditions.

[0109] The structural principle of the drive component 400, which is controlled by cylinder 430, is as follows:

[0110] Furthermore, such as Figure 7 As shown, the drive unit 400 includes a plurality of cylinders 430 arranged opposite to each other. The cylinder body of the cylinder 430 is disposed on the support body 100. The piston rod of the cylinder 430 is connected to the drive plate 200 and drives the drive plate 200 to move between a first position and a second position.

[0111] The cylinder body of cylinder 430 can be detachably connected to the support body 100 via threaded connection, plug-in connection, or other methods. One end of the piston rod of cylinder 430 is connected to the drive plate 200. When cylinder 430 is charged or discharged, the piston rod will move linearly within the cylinder body, thereby pushing or pulling the drive plate 200. When it is necessary to increase the size of opening 310, the control system will supply air to cylinder 430, causing the piston to extend and apply a thrust to drive plate 200 toward the second position, opening the guide vane 320 to increase the ventilation area. Conversely, if it is necessary to decrease the size of opening 310, the control system will discharge the gas within the cylinder body, causing the piston to retract and driving drive plate 200 back to the first position, reducing the ventilation area.

[0112] Furthermore, it also includes a control component electrically connected to the drive component 400 and used to control the distance between the support body 100 and the drive plate 200 through the drive component 400, so as to control the size of the opening 310 of the opening and closing assembly 300 in the first and second states.

[0113] This control unit can be programmed using control elements such as circuit boards, and controls the movement of the drive board 200 through its connection with the drive unit 400. Specifically:

[0114] When the drive unit 400 uses the motor 410 as the power source, the control unit is electrically connected to the motor 410. By controlling the rotation direction of the output end of the motor 410, the movement direction of the drive plate 200 is controlled, thereby changing the size of the opening 310.

[0115] When the drive unit 400 uses the cylinder 430 as its power source, a solenoid valve can be connected between the control unit and the cylinder 430. Through the electrical connection between the control unit and the solenoid valve, the flow rate and pressure of compressed air entering the cylinder 430 can be precisely controlled, allowing for rapid response and adjustment of the piston position.

[0116] Furthermore, it also includes a temperature sensor, which is electrically connected to the control unit. The temperature sensor is used to monitor temperature changes in the controlled area. Based on these temperature changes, the control unit can adjust the area and airflow of the opening 310 by moving the drive plate 200, thereby achieving a constant temperature within the controlled area. Specifically:

[0117] This mode includes shutdown mode, normal mode, and turbo mode.

[0118] In the power-off mode: when the driver board 200 is in the first position and the opening 310 is in the first closed state, the electronic components in the control area are in the power-off state. The closed state of the opening 310 can prevent external dust from entering the control area.

[0119] In normal mode: When the electronic components in the control area need to work, the controller sends a command to the drive unit 400, which moves the drive board 200 to a position between the first position and the second position, so that the opening 310 is half open, allowing an appropriate amount of airflow to maintain the normal heat dissipation requirements of the equipment. At this time, the speed of the external fan is limited to below 3000 RPM to provide a moderate cooling effect without consuming too much energy.

[0120] When the temperature sensor detects that the temperature in the control area is too high, the speed of the external fan increases to more than 3000 RPM. The controller sends a command to the drive unit, which moves the drive board 200 to the second position and the opening 310 is fully opened to the second state to maximize airflow and quickly reduce the internal temperature of the equipment.

[0121] The above control method enables dynamic ventilation control, which automatically adjusts the position of the guide vane 320 and the speed of the fan according to the actual operating status of the system and the external ambient temperature, thereby optimizing heat dissipation efficiency and saving energy.

[0122] Its technical effects are as follows:

[0123] In low-temperature environments, it reduces unnecessary energy consumption and extends the lifespan of fans and other components.

[0124] It responds quickly in high-temperature environments to prevent overheating and protect sensitive electronic components from damage.

[0125] It provides a smooth transition from complete shutdown to full power operation, ensuring a consistent user experience and device security.

[0126] The use of this device can significantly improve the reliability and performance of electronic equipment, while also contributing to energy conservation and emission reduction. Furthermore, this control method can be further integrated into more complex monitoring and management systems to achieve remote monitoring and automated management.

[0127] Example 3

[0128] The airflow control device in Embodiment 1 can be integrated into various industrial equipment such as computers, medical devices, servers, and charging piles. This embodiment provides an electronic device, such as... Figure 8 As shown, it includes:

[0129] The enclosure has an exhaust chamber 1 inside; the exhaust chamber 1 has an air inlet 2 and an air outlet 3.

[0130] An exhaust mechanism is installed inside the exhaust chamber 1 and is used to discharge the gas inside the exhaust chamber 1 out of the exhaust chamber 1 through the air outlet 3.

[0131] The air volume control device includes a support body 100, an opening and closing component 300, and a drive plate 200. The opening and closing component 300 has an opening 310 communicating with the air inlet 2. When the drive plate 200 is in the first position, the opening 310 of the opening and closing component 300 is in the first state. When the drive plate 200 is in the second position, the opening 310 of the opening and closing component 300 is in the second state. The opening 310 in the first state and the second state are different in size.

[0132] Through the integration of airflow control and the connection between opening 310 and air inlet 2, the airflow in exhaust chamber 1 can be effectively controlled by adjusting the ventilation area of ​​opening 310, specifically:

[0133] When the drive plate 200 is in the first position, the opening 310 of the opening and closing assembly 300 is small or completely closed, allowing less air to flow in. When the drive plate 200 moves to the second position, the opening 310 of the opening and closing assembly 300 becomes larger, allowing more air to enter the exhaust chamber 1.

[0134] The electronic devices employing this structure offer the following technical advantages:

[0135] High-efficiency heat dissipation: By precisely controlling the air intake and combining it with an effective exhaust mechanism, heat dissipation efficiency can be significantly improved, ensuring that the equipment maintains a stable operating temperature even when running under high load.

[0136] Energy saving and noise reduction: Compared with the traditional fan speed adjustment method, this method is more energy-efficient and produces less noise because it does not require frequent adjustment of fan speed to adapt to different heat dissipation needs.

[0137] Highly flexible: It can adjust the ventilation volume according to actual needs, and can respond quickly to both slight temperature fluctuations and large changes in heat dissipation requirements.
