Abstract
Description
Technical Field
[0001] This application relates to the field of smart terminal technology, specifically to a heat dissipation device and a smart terminal. Background Technology
[0002] With the rapid development of next-generation chip technology and 5G communication technology, the computing performance and communication capabilities of smart terminal devices have significantly improved, but their power consumption has also increased exponentially. At the same time, consumer demand for thinner, lighter, and more portable terminals continues to drive product iterations towards compactness, resulting in a sharp increase in internal heat flux density. This contradiction presents unprecedented challenges to the design of cooling systems for smart terminals.
[0003] In conceiving and implementing this application, the inventors discovered at least the following problems: Currently, mainstream smart terminals generally employ passive cooling solutions, transferring heat from the inside of the mobile terminal to the screen and back cover through radiation and heat conduction. The screen and back cover then exchange heat with the environment, thereby controlling the surface temperature of the smart terminal. However, when the device is under high load (such as 3D game rendering, 4K video recording, or multitasking), the heat generated by the smart terminal remains at a high level. In this situation, passive cooling alone cannot dissipate the heat to the outside of the smart terminal in a timely manner, leading to severe overheating. This not only affects user experience and the overall lifespan of the device but can also cause serious safety accidents such as burns and explosions. Therefore, improving the heat dissipation effect of smart terminals has become an urgent technical challenge.
[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0005] The purpose of this application is to provide a heat dissipation device and a smart terminal, which aims to solve the problem of low heat dissipation efficiency of smart terminals.
[0006] To address the aforementioned technical problems, this application provides a heat dissipation device, comprising: a frame assembly, a housing, a shielding assembly, a circuit board, and a temperature sensor signal-connected to the circuit board. The frame assembly includes a side frame and a support member disposed on the side frame. An air inlet is provided on one side of the side frame, and an air outlet is provided on the other side of the side frame. The housing is disposed on the support member and forms an air duct with the air inlet and the air outlet. The shielding assembly is used to adjust the size of the air inlet and the air outlet. The shielding assembly is movably disposed on both sides of the side frame. The circuit board is disposed on the support member.
[0007] Optionally, the heat dissipation device further includes a drive component disposed on the support member and pulsatorically connected to the shielding components on both sides of the side frame, the drive component being used to drive the shielding components to move on the side frame, so that the shielding components adjust the size of the air inlet and the air outlet. The circuit board further includes a control component for controlling the drive component to open or close, the control component being signal-connected to the temperature sensor and electrically connected to the drive component.
[0008] Optionally, the shielding assembly includes a guide rail fixedly disposed on the inner side of the side frame and a first shielding member movably disposed on the guide rail, wherein the first shielding member is connected to the driving member in a transmission manner.
[0009] Optionally, the first shielding member includes a first shielding portion and a first connecting portion connected to the first shielding portion, wherein the first connecting portion is drively connected to the driving member.
[0010] Optionally, the air inlet and the air outlet are arranged opposite to each other.
[0011] Optionally, the air inlet is one of a rectangular hole, an elliptical hole, a circular hole, or an oblong hole, and the air outlet is one of a rectangular hole, an elliptical hole, a circular hole, or an oblong hole.
[0012] Optionally, the first shielding member further includes a first protrusion provided on the first connecting portion for pushing the first shielding member to move on the guide rail. Limiting holes are provided on both sides of the side frame, and the limiting holes are used to limit the displacement of the first protrusion. The first protrusion is movably inserted into the limiting holes.
[0013] Optionally, the first shielding member further includes an opening disposed between the first shielding portion and the first connecting portion, the opening being used to open the air inlet and the air outlet.
[0014] Optionally, the heat dissipation device further includes a switch disposed on one side of the side frame for controlling the opening or closing of the drive component, the switch being electrically connected to the drive component.
[0015] Optionally, the shielding assembly includes a guide rail fixedly disposed on the inner side of the side frame and a second shielding member movably disposed on the guide rail. The second shielding member includes a second protrusion for pushing the second shielding member to move on the guide rail. Limiting holes are respectively provided on both sides of the side frame. The limiting holes are used to limit the displacement of the second protrusion. The second protrusion is movably disposed within the limiting holes.
[0016] Optionally, the second shielding member further includes a second shielding portion and a second connecting portion connected to the second shielding portion, wherein the second protrusion is disposed on the second connecting portion.

The display screen is disposed on the support member, the cover is disposed at the end of the side frame away from the display screen, and the battery is disposed between the cover and the support member.
[0018] The heat dissipation device of this application can monitor the internal temperature of the smart terminal in real time by setting a temperature sensor. According to the internal temperature of the smart terminal, the shielding component adjusts the size of the air inlet and outlet. When the internal temperature of the smart terminal is high and the heat dissipation demand is high, the shielding component makes the air inlet and outlet fully open. When the internal temperature of the smart terminal is moderate and the heat dissipation demand is low, the shielding component makes the air inlet and outlet partially open. When the internal temperature of the smart terminal is low and there is no heat dissipation demand, the shielding component makes the air inlet and outlet completely closed to prevent moisture and dust from entering the smart terminal. This design not only improves the heat dissipation and dust prevention effect, but also meets the heat dissipation needs in different scenarios.

[0055] Figure 1 For a hardware structure diagram of a mobile terminal that implements various embodiments of this application, please refer to... Figure 1This is a schematic diagram of the hardware structure of a smart terminal implementing various embodiments of this application. The smart terminal 100 may include: an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111, etc. Those skilled in the art will understand that... Figure 1 The smart terminal structure shown does not constitute a limitation on the smart terminal. A smart terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0056] The following is combined Figure 1 A detailed introduction to each component of the smart terminal:
[0057] The radio frequency unit 101 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 110; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, and a duplexer. Furthermore, the radio frequency unit 101 can also communicate wirelessly with networks and other devices.

[0058] WiFi is a short-range wireless transmission technology. Smart terminals, through the WiFi module 102, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a smart terminal and can be omitted as needed without changing the essence of the invention.
[0059] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the smart terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the smart terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.
[0060] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage media) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.
[0061] The smart terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

Optionally, the ambient light sensor can adjust the brightness of the panel 1061 according to the ambient light level, and the proximity sensor can turn off the panel 1061 and / or backlight when the smart terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that can also be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.
[0064] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides corresponding visual output on the panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the smart terminal. The specific implementation is not limited here.
[0065] Interface unit 108 serves as an interface through which at least one external device can connect to smart terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 108 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within smart terminal 100, or it may be used to transmit data between smart terminal 100 and the external device.
[0066] The memory 109 can be used to store software programs and various data. The memory 109 may primarily include a program storage area and a data storage area.

Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.
[0067] The processor 110 is the control center of the smart terminal. It connects various parts of the smart terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the smart terminal, thereby providing overall monitoring of the smart terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.
[0068] The smart terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.
[0069] although Figure 1 As not shown, the smart terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.
[0070] To facilitate understanding of the embodiments of this application, the communication network system on which the smart terminal of this application is based is described below.

PCRF2036 is the policy and charging control decision point for service data flow and IP bearer resources. It selects and provides available policy and charging control decisions for the policy and charging enforcement function unit (not shown in the figure).
[0075] IP services 204 may include the Internet, intranet, IMS (IP Multimedia Subsystem), or other IP services.
[0076] Although the above description uses the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation.
[0077] Based on the above-described intelligent terminal hardware structure and communication network system, various embodiments of this application are proposed.
[0078] First Embodiment
[0079] Figure 3 This is an exploded perspective view of the heat dissipation device according to the first embodiment of this application. Figure 4 This is a schematic diagram of the heat dissipation device according to the first embodiment of this application with the air inlet and air outlet in a completely closed state. Figure 5 This is a schematic diagram of the heat dissipation device according to the first embodiment of this application with the air inlet and air outlet fully open. Figure 6This is a side view of the heat dissipation device of the first embodiment of this application with the air inlet and air outlet fully open. Figure 7 This is a side view of the first shielding member of the heat dissipation device according to the first embodiment of this application. Figure 8 This is a front view of the first shielding member of the heat dissipation device according to the first embodiment of this application. Figure 9 This is a schematic diagram of the heat dissipation device of the first embodiment of this application with the air inlet and air outlet in a completely closed state, as shown below. Figure 3-9 As shown, a heat dissipation device includes: a frame assembly 1, a housing 2, a shielding assembly 3, a circuit board 4, and a temperature sensor 41 connected to the circuit board 4. The frame assembly 1 includes a side frame 11 and a support member 12 disposed on the side frame 11. An air inlet 111 is provided on one side of the side frame 11, and an air outlet 112 is provided on the other side of the side frame 11. The housing 2 is disposed on the support member 12 and forms an air duct with the air inlet 111 and the air outlet 112. The shielding assembly 3 is used to adjust the size of the air inlet 111 and the air outlet 112. The shielding assembly 3 is movably disposed on both sides of the side frame 11. The circuit board 4 is disposed on the support member 12.
[0080] In this embodiment, the temperature sensor 41 is mounted on the circuit board 4, which can monitor the temperature of the circuit board 4 in real time and convert it into a signal transmitted to the circuit board 4. The circuit board 4 transmits its temperature information to the display screen 7 of the smart terminal for display. The housing 2 abuts against the circuit board 4, allowing the heat of the circuit board 4 to be transferred to the housing 2. The shielding components 3 are movably mounted on both sides of the side frame 11, located at the air inlet 111 and the air outlet 112 respectively. The size of the air inlet 111 and the air outlet 112 can be adjusted by moving them on the side frame 11. Figures 5-6 As shown, when the temperature of circuit board 4 is high and the heat dissipation demand is high, the shielding component 3 moves to fully open the air inlet 111 and the air outlet 112. External air enters the housing 2 from the air inlet 111 on one side of the side frame 11 and exchanges heat with the wall of the housing 2 before being exhausted from the air outlet 112 on the other side of the side frame 11. This provides the best heat dissipation. When the temperature of circuit board 4 is not too high and the heat dissipation demand is low, the shielding component 3 moves to partially open the air inlet 111 and the air outlet 112. Some external air enters the housing 2 from the air inlet 111 on one side of the side frame 11 and exchanges heat with the wall of the housing 2 before being exhausted from the air outlet 112 on the other side of the side frame 11. This ensures the safe use of the smart terminal and optimal heat dissipation. Figure 4 and Figure 9 As shown, when the temperature of the circuit board 4 is low and there is no need for heat dissipation, the shielding component 3 moves to completely close the air inlet 111 and the air outlet 112, preventing moisture and dust from entering the smart terminal. This design not only improves the heat dissipation and dust prevention effects, but also meets the heat dissipation needs in different scenarios.
[0081] Optionally, the shielding components 3 can be movably disposed on both outer sides of the side frame 11, or movably disposed on both inner sides of the side frame 11, such as... Figure 4-5 and Figure 9 As shown, in this embodiment, the shielding components 3 are movably disposed on the two inner sides of the side frame 11, which can save external space and improve the overall space utilization.
[0082] Optionally, such as Figure 4-5 and Figure 9 As shown, the heat dissipation device also includes a drive component 5 disposed on the support member 12 and respectively connected to the shielding components 3 on both sides of the side frame 11. The drive component 5 is used to drive the shielding components 3 to move on the side frame 11, so that the shielding components 3 adjust the size of the air inlet 111 and the air outlet 112. The circuit board 4 also includes a control component 42 for controlling the drive component 5 to open or close. The control component 42 is signal-connected to the temperature sensor 41 and electrically connected to the drive component 5.
[0083] Temperature sensor 41 monitors the temperature of circuit board 4 in real time. When the temperature of circuit board 4 reaches a certain value, controller 42 automatically activates drive component 5. Drive component 5 drives shielding component 3 to move, thereby moving air inlet 111 and air outlet 112 from the closed state to the open state, ensuring the safety of mobile terminal use. When the temperature of circuit board 4 drops below a certain value, controller 42 controls drive component 5 to move shielding component 3, thereby moving air inlet 111 and air outlet 112 from the open state to the closed state, preventing moisture and dust from entering the smart terminal. This achieves intelligent temperature regulation of circuit board 4, optimizes heat dissipation, and achieves better heat dissipation effect. In this embodiment, drive component 5 is a motor.
[0084] Optionally, such as Figure 4-5 and Figure 9 As shown, the shielding assembly 3 includes a guide rail 31 fixedly disposed on the inner side of the side frame 11 and a first shielding member 32 movably disposed on the guide rail 31. The first shielding member 32 is connected to the driving member 5 in a transmission connection.
[0085] By setting the guide rail 31, the first blocking component 32 can move more conveniently, and at the same time, it can also play a certain limiting role.
[0086] Optionally, such as Figure 4-5 as well as Figure 7-9 As shown, the first shielding member 32 includes a first shielding part 321 and a first connecting part 322 connected to the first shielding part 321. The first connecting part 322 is connected to the driving member 5 in a transmission manner.
[0087] In this embodiment, the size of the air inlet 111 and the air outlet 112 is adjusted by the first shielding part 321, and the first connecting part 322 is movably disposed on the guide rail 31.
[0088] Optionally, such as Figure 3-5 as well as Figure 9 As shown, the air inlet 111 and the air outlet 112 are arranged opposite to each other.
[0089] In this embodiment, the axes of the air inlet 111 and the air outlet 112 are on a straight line, which is conducive to the rapid circulation of external air and heat exchange.
[0090] Optionally, the air inlet 111 is one of a rectangular hole, an elliptical hole, a circular hole, or an oblong hole, and the air outlet 112 is one of a rectangular hole, an elliptical hole, a circular hole, or an oblong hole.
[0091] The type of air inlet 111 and air outlet 112 can be selected according to actual needs. For example, for the purpose of saving space, the air inlet 111 is an oblong hole and the air outlet 112 is an oblong hole.
[0092] Optionally, such as Figure 9 As shown, the heat dissipation device also includes a switch 8 disposed on one side of the side frame 11 for controlling the opening or closing of the drive component 5, and the switch 8 is electrically connected to the drive component 5.
[0093] When the control component 42 malfunctions and cannot automatically start the drive component 5, the switch component 8 can control the start and stop of the drive component 5 to ensure the normal operation of the heat dissipation function.
[0094] Second Embodiment
[0095] The heat dissipation device in this embodiment is largely the same as the heat dissipation device in the first embodiment, except that the first shielding member 32 is different. Figure 10 This is a schematic diagram of the heat dissipation device according to the second embodiment of this application with the air inlet and air outlet in a completely closed state. Figure 11 This is a schematic diagram of the heat dissipation device according to the second embodiment of this application with the air inlet and air outlet fully open. Figure 12 This is a side view of the heat dissipation device according to the second embodiment of this application with the air inlet and air outlet fully open. Figure 13 This is a side view of the first shielding member of the heat dissipation device according to the second embodiment of this application. Figure 14 This is a front view of the first shielding member of the heat dissipation device according to the second embodiment of this application, as shown in the figure. Figure 10-14As shown, the first blocking member 32 also includes a first protrusion 323 provided on the first connecting part 322 for pushing the first blocking member 32 to move on the guide rail 31. Limiting holes 113 are provided on both sides of the side frame 11. The limiting holes 113 are used to limit the displacement of the first protrusion 323. The first protrusion 323 is movably inserted into the limiting hole 113.
[0096] In this embodiment, as Figure 10-12 As shown, the limiting hole 113 has a first end and a second end. The first protrusion 323 is used to push the first connecting part 322 to move on the guide rail 31. When the first protrusion 323 moves to the first end of the limiting hole 113, the first blocking part 321 completely blocks the air inlet 111 and the air outlet 112, making the air inlet 111 and the air outlet 112 completely closed. When the first protrusion 323 moves to the second end of the limiting hole 113, the first blocking part 321 does not block the air inlet 111 and the air outlet 112, making the air inlet 111 and the air outlet 112 completely open. The displacement of the first connecting part 322 on the guide rail 31 can be limited by the first protrusion 323 and the limiting hole 113 to ensure its stability. At the same time, the user can adjust the size of the air inlet 111 and the air outlet 112 by pushing the first protrusion 323 according to their own needs to meet the user's heat dissipation requirements. In addition, when the control unit 42 malfunctions and cannot automatically start the drive unit 5, heat dissipation can also be achieved manually.

Figure 15 This is a schematic diagram of the heat dissipation device according to the third embodiment of this application with the air inlet and air outlet fully open. Figure 16 This is a side view of the heat dissipation device according to the third embodiment of this application with the air inlet and air outlet fully open. Figure 17 This is a schematic diagram of the heat dissipation device according to the third embodiment of this application with the air inlet and air outlet in a completely closed state. Figure 18 This is a side view of the first shielding member of the heat dissipation device according to the third embodiment of this application.

[0099] In this embodiment, as Figure 15-19As shown, the limiting hole 113 has a first end and a second end opposite to each other, and the opening 324 is provided with a through hole for external air to pass through. When the first protrusion 323 moves to the first end of the limiting hole 113, the opening 324 is located at the air inlet 111 and the air outlet 112 respectively, so that the air inlet 111 and the air outlet 112 are in a fully open state. When the first protrusion 323 moves to the second end of the limiting hole 113, the first blocking part 321 completely blocks the air inlet 111 and the air outlet 112, so that the air inlet 111 and the air outlet 112 are in a fully closed state.

Figure 21 This is a schematic diagram of the heat dissipation device according to the fourth embodiment of this application with the air inlet and air outlet fully open. Figure 22 This is a side view of the heat dissipation device according to the fourth embodiment of this application with the air inlet and air outlet fully open. Figure 23 This is a side view of the first shielding member of the heat dissipation device according to the fourth embodiment of this application. Figure 24 This is a front view of the first shielding member of the heat dissipation device according to the fourth embodiment of this application, as shown in the figure. Figure 20-24 As shown, the heat dissipation device includes: a frame assembly 1, a housing 2, a shielding assembly 3, a circuit board 4, and a temperature sensor 41 connected to the circuit board 4. The frame assembly 1 includes a side frame 11 and a support member 12 disposed on the side frame 11. An air inlet 111 is provided on one side of the side frame 11, and an air outlet 112 is provided on the other side of the side frame 11.

The circuit board 4 is disposed on the support member 12.
[0102] In this embodiment, the temperature sensor 41 is disposed on the circuit board 4, which can monitor the temperature of the circuit board 4 in real time and convert it into a signal and transmit it to the circuit board 4. The circuit board 4 transmits its temperature information to the display screen 7 of the smart terminal for display. The housing 2 abuts against the circuit board 4, so that the heat of the circuit board 4 can be transferred to the housing 2. The shielding component 3 is movably disposed on both sides of the side frame 11 and located at the air inlet 111 and the air outlet 112 respectively. The size of the air inlet 111 and the air outlet 112 can be adjusted by moving it on the side frame 11.

The second protrusion 333 is movably disposed in the limiting hole 113.
[0104] In this embodiment, the limiting hole 113 has a first end and a second end. When the second protrusion 333 moves to the first end of the limiting hole 113, the second blocking member 33 completely blocks the air inlet 111 and the air outlet 112, making the air inlet 111 and the air outlet 112 completely closed. When the second protrusion 333 moves to the second end of the limiting hole 113, the second blocking member 33 does not block the air inlet 111 and the air outlet 112, making the air inlet 111 and the air outlet 112 completely open. The second protrusion 333 and the limiting hole 113 can limit the displacement of the second blocking member 33 on the guide rail 31, ensuring its stability. At the same time, the user can adjust the size of the air inlet 111 and the air outlet 112 by pushing the second protrusion 333 according to their own needs, so as to meet the user's heat dissipation requirements.

[0106] In this embodiment, the second connecting part 332 is movably disposed on the guide rail 31, and the second protrusion 333 is used to push the second connecting part 332 to move on the guide rail 31. When the second protrusion 333 moves to the first end of the limiting hole 113, the second blocking part 331 completely blocks the air inlet 111 and the air outlet 112 respectively, so that the air inlet 111 and the air outlet 112 are in a completely closed state. When the second protrusion 333 moves to the second end of the limiting hole 113, the second blocking part 331 does not block the air inlet 111 and the air outlet 112, so that the air inlet 111 and the air outlet 112 are in a completely open state.
