Description

Technical Field

[0001] The present disclosure relates to the technical field of heat dissipation devices, and in particular, to a heat dissipation component and an electronic device. Background Art

[0002] Nowadays, users have increasingly high requirements for the performance of computers, which leads to an increasing power consumption of chips. In particular, AI chips dedicated to processing a large number of computing tasks in artificial intelligence applications, although having a high processing efficiency, also have a greater power consumption, and the system generates more heat, resulting in higher temperatures of the C-shell and D-shell of the laptop computer and a poor user experience.

[0003] The existing solution is to adopt a double-outlet fan design. Its main air outlet is used to dissipate heat from the CPU, and another air outlet is opened on the side of the fan as a second air outlet to divert a part of the air to blow towards the C-shell and D-shell to reduce the temperature of the casing. However, the existing fan structure designs on the market are all continuously blowing air through the double air outlets, and the second air outlet cannot be switched on and off according to different functional requirements. When the second air outlet is not needed, it is open for a long time, resulting in the fan blades being exposed outside. When the fan starts to rotate, more dust is sucked into and accumulated inside the fan and on the fan blades, which easily leads to a weakening of the fan performance and a shorter service life. In addition, continuous blowing heat dissipation will also affect the heat dissipation effect of the CPU and reduce the heat dissipation efficiency. Summary of the Utility Model

[0004] The present disclosure provides a heat dissipation component and an electronic device to at least solve the above technical problems existing in the prior art.

[0009] In an implementable embodiment, a guide rail structure is fixedly arranged on the side wall. The guide rail structure includes opposite first guide rail and second guide rail. The first guide rail and the second guide rail are arranged at intervals along a first direction, and the first guide rail and the second guide rail meet the parallel condition. The stop structure is slidably connected to the guide rail structure.

[0010] In an implementable embodiment, first sliding parts and second sliding parts are respectively arranged on two side edges of the stop structure. The first sliding parts and the second sliding parts are respectively slidably connected to the first guide rail and the second guide rail.

[0011] In an implementable embodiment, the driving structure includes a driving member, a rotating shaft connected to the driving member, and a gear fixed on the rotating shaft. The driving member is arranged on the housing. The rotating shaft is arranged along the first direction. The gear is connected to the stop structure.

[0012] In an implementable embodiment, the stop structure includes a first surface located in the accommodating space and a second surface opposite to the first surface. A plurality of grooves for engaging with the teeth of the gear are formed on the first surface. The second surface is a closed surface.

[0013] In an implementable embodiment, the driving structure includes a driving member, a rotating shaft connected to the driving member, and a gear sleeved on the rotating shaft. The driving member is arranged on the housing. The rotating shaft is arranged along the first direction. A rack is arranged on the stop structure. The gear is meshed and connected with the rack.

[0014] In an implementable embodiment, the first guide rail and the second guide rail are in a convex shape. The first sliding parts and the second sliding parts are grooves respectively imitating the first guide rail and the second guide rail.

[0015] In an implementable embodiment, the first guide rail and the second guide rail are grooves. The first sliding parts and the second sliding parts are convex blocks respectively imitating the first guide rail and the second guide rail.

[0016] In an implementable embodiment, the stop structure has at least a first position and a second position in the guide rail structure. When the stop structure is in the first position, the stop structure covers the air outlet, so that the air outlet is in a closed state. When the stop structure is in the second position, the air outlet is in an open state.

[0017] According to a second aspect of the present disclosure, an electronic device is provided, including a housing and electronic components disposed inside the housing. A heat dissipation component as described in any of the above implementable embodiments is further disposed inside the housing. The air outlet is correspondingly disposed opposite to the electronic components, so that the air blown by the fan can pass through the air outlet and blow towards the electronic components.

[0018] In the present disclosure, since an air outlet is provided on the side wall of the heat dissipation component, the air of the fan in the accommodation space can be blown out from the air outlet to dissipate heat from the wafer, components or the housing of the notebook computer.

Detailed implementation manners

[0029] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0030] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0031] Referring to Figures 1 to 3 As shown, a heat dissipation component according to an exemplary embodiment of the present disclosure includes a housing 1, a fan 2, a side wall 3, a stop structure 4, and a drive structure 5. The side wall 3 and the housing 1 enclose an accommodation space 30, and the side wall 3 is provided with an air outlet 31. The fan 2 is located in the accommodation space 30; the stop structure 4 is slidably connected to the side wall 3, and the stop structure 4 can at least completely cover the air outlet 31 to block the air blown by the fan 2 from blowing out through the air outlet 31; the drive structure 5 is disposed beside the side wall 3 and within the accommodation space 30, and the drive structure 5 is connected to the stop structure 4 and can drive the stop structure 4 to move along the extension direction of the side wall 3 to adjust the relative position between the stop structure 4 and the air outlet 31.

[0032] In this embodiment, the heat dissipation component is applied to various scenarios that require heat dissipation functions. For example, it can be applied to, including but not limited to, computers, game consoles, industrial equipment, or communication equipment, etc. The size of the stop structure 4 is based on the standard that it can at least completely block the air outlet 31. When the stop structure 4 and the air outlet 31 overlap, the air from the fan 2 is blocked within the side wall 3. The driving structure 5 is connected to the stop structure 4 to push the stop structure 4 to block the air outlet 31 or open the air outlet 31. The air outlet 31 is usually arranged corresponding to the heat-generating components to blow air on the heat-generating components for heat dissipation, and at the same time, it can also dissipate heat from the C shell (referring to the shell around the keyboard and touchpad of the laptop) and the D shell (referring to the lower shell in contact with the desktop at the bottom of the laptop) of the laptop. The stop structure 4 is arranged beside the side wall 3. Specifically, the side beside the side wall 3 is the inner side close to the fan 2 or the outer side far from the fan 2. When the stop structure 4 is arranged on the outer side of the side wall 3, correspondingly, the driving structure 5 is also located on the outer side of the side wall 3, so that the driving structure 5 can be connected to the stop structure 4 and drive it to move along the extending direction of the side wall 3; when the stop structure 4 is arranged on the inner side of the side wall 3, correspondingly, the driving structure 5 is also located on the inner side of the side wall 3, so that the driving structure 5 can be connected to the stop structure 4 and drive it to move along the extending direction of the side wall 3. In the embodiments shown in this disclosure, the example is taken where the stop structure 4 is located on the inner side of the side wall 3 and the driving structure 5 is also arranged in the accommodation space 30 on the inner side of the side wall 3. The control system is connected to the driving structure 5 through the control line 53. Specifically, when the CPU generates a relatively high amount of heat during high-load operation, this heat is captured by the CPU temperature sensor. For example, initially, the air outlet 31 is in the closed state, that is, the stop structure 4 overlaps with the air outlet 31 to block the air outlet 31. When the CPU temperature sensor captures that the CPU temperature reaches 65°, the EC sends an instruction to open the air outlet 31 to the fan IC. The fan IC controls the driving structure 5 to drive the stop structure 4 to move through the control line 53, so as to move the stop structure 4 away from the air outlet 31, making the air outlet 31 in a ventilated state; when the CPU sensor captures that the CPU temperature is less than 65°, the EC sends an instruction to close the air outlet 31 to the fan IC. The fan IC controls the driving structure 5 to drive the stop structure 4 to move in the opposite direction through the control line 53, so as to block the air outlet 31 with the stop structure 4, making the air outlet 31 in the closed state. Among them, the EC is a single-chip microcomputer, commonly used in laptops, responsible for various functions such as keyboard control, touchpad, power management, fan control, and laptop battery management; the fan IC is an integrated circuit specifically used for fan control and management. It realizes functions such as starting, speed regulation, or protection of the fan by receiving control signals. In a laptop, the fan IC is responsible for adjusting the on / off or speed of the fan according to the heat dissipation requirements of the system to ensure the stable operation of the system. It can be understood that the 65° in the above temperature is not limited to this temperature and can be adaptively set according to actual needs.

[0033] In this embodiment, since an air outlet 31 is formed on the side wall 3 of the heat dissipation component, the air from the fan 2 in the accommodation space 30 can be blown out from the air outlet 31 to dissipate heat from the wafer, components or the outer shell of the laptop; since the heat dissipation component further includes a stop structure 4 and a driving structure 5, the driving structure 5 can control the stop structure 4 to move along the extending direction of the side wall 3, so that when the stop structure 4 moves to coincide with the air outlet 31, the stop structure 4 blocks the air outlet 31 to prevent the air from the fan 2 from being blown out from the air outlet 31; when the stop structure 4 is removed from the air outlet 31, the air from the fan 2 can be blown out from the air outlet 31. Thus, the heat dissipation component can switch the air outlet 31 on and off according to different functional requirements, solves the problem of dust accumulation caused by the continuous opening of the air outlet 31, improves the performance of the heat dissipation component, increases the heat dissipation efficiency, and can extend the service life. Specifically, when the user runs software with a small load, such as a word processor application, etc., the driving structure 5 will control the stop structure 4 to keep the air outlet 31 closed; when the user runs software with a large load, such as a game software or a simulation software, etc., the driving structure 5 will control the stop structure 4 to keep the air outlet 31 in a ventilated state to blow the heat-generating components, the C-shell and the D-shell, so as to reduce the temperature and improve the user experience.

[0034] Refer to Figure 4 As shown, in an implementable embodiment, a guide rail structure 6 is fixedly arranged on the side wall 3. The guide rail structure 6 includes opposite first guide rail 61 and second guide rail 62. The first guide rail 61 and the second guide rail 62 are arranged at intervals in a first direction and the first guide rail 61 and the second guide rail 62 meet the parallel condition. The stop structure 4 is slidably connected to the guide rail structure 6.

[0035] Specifically, in an implementable embodiment, first sliding parts 41 and second sliding parts 42 are respectively arranged on two sides of the stop structure 4. The first sliding parts 41 and the second sliding parts 42 are respectively slidably connected to the first guide rail 61 and the second guide rail 62.

[0036] In this embodiment, the guide rail structure 6 is fixedly arranged inside the side wall 3. The guide rail structure 6 can extend from the position of the air outlet 31 to the position where the air outlet 31 can be fully ventilated by the stop structure 4, or the guide rail structure 6 can also extend over the entire side wall 3. The first direction is the Z-axis direction in the three-dimensional coordinate system. The stop structure 4 is arranged between the first guide rail 61 and the second guide rail 62. The first sliding part 41 is slidably connected to the first guide rail 61, and the second sliding part 42 is slidably connected to the second guide rail 62, so that the stop structure 4 can slide along the guide rail structure 6. The stop structure 4 can be made of, including but not limited to, Polybutylene Terephthalate (PBT). PBT material is an important thermoplastic polyester, which has high heat resistance and can maintain the stability of its physical and chemical properties at relatively high temperatures; PBT material also has good toughness and fatigue resistance, good self-lubrication, and a low friction coefficient, so that the relative movement between the stop structure 4 and the guide rail structure 6 can be stable and smooth.

[0037] In an implementable embodiment, the stop structure 4 has at least a first position and a second position within the guide rail structure 6. When the stop structure 4 is in the first position, the stop structure 4 covers the air outlet 31, making the air outlet 31 in a closed state; when the stop structure 4 is in the second position, the air outlet 31 is in an open state.

[0038] Further, referring to Figures 4 to 6 As shown, in an implementable embodiment, the first guide rail 61 and the second guide rail 62 are in a convex shape, and the first sliding part 41 and the second sliding part 42 are grooves respectively conforming to the first guide rail 61 and the second guide rail 62.

[0039] Alternatively, in an implementable embodiment, the first guide rail 61 and the second guide rail 62 are grooves, and the first sliding part 41 and the second sliding part 42 are convex blocks respectively conforming to the first guide rail 61 and the second guide rail 62.

[0040] In this embodiment, the first sliding part 41 and the second sliding part 42 in the groove structure slide along the convex guide rail, which can prevent the stop structure 4 from disengaging from the guide rail structure 6, and the structure is reliable and stable; similarly, when the first guide rail 61 and the second guide rail 62 are grooves, the convex first sliding part 41 and the second sliding part 42 slide along the groove guide rail, which can prevent the stop structure 4 from disengaging from the guide rail structure 6, and the structure is reliable and stable. It can be understood that the cooperation between the first guide rail 61 and the first sliding part 41 and between the second guide rail 62 and the second sliding part 42 is not limited to the above manner, as long as it can ensure that the stop structure 4 slides along the guide rail structure 6 and does not disengage from the guide rail structure 6.

[0041] In an implementable embodiment, the driving structure 5 includes a driving member, a rotating shaft 51 connected to the driving member, and a gear 52 fixed on the rotating shaft 51. The driving member is arranged on the housing 1. The rotating shaft 51 is arranged along a first direction, and the gear 52 is connected to the stop structure 4.

[0042] Specifically, in an implementable embodiment, the stop structure 4 includes a first surface located in the accommodating space 30 and a second surface opposite to the first surface. A plurality of grooves 43 for meshing with the teeth of the gear 52 are formed on the first surface, and the second surface is a closed surface.

[0043] In this embodiment, the driving member (not shown in the figure) is a small motor, which is small in size and light in weight and can convert electrical energy into mechanical energy. The control system is electrically connected to the small motor through a control line 53. The small motor can control the rotating shaft 51 to rotate clockwise or counterclockwise, thereby driving the gear 52 to rotate clockwise or counterclockwise. When the gear 52 rotates clockwise, the teeth on the gear 52 are sequentially meshed with a plurality of grooves 43 on the first surface, so that the stop structure 4 moves away from the air outlet 31 along the extending direction of the side wall 3; when the gear 52 rotates counterclockwise, the teeth on the gear 52 are sequentially meshed with a plurality of grooves 43 on the first surface in the opposite direction, so that the stop structure 4 moves toward the air outlet 31 along the extending direction of the side wall 3. Specifically, it is assumed that the air outlet 31 is initially in a closed state, that is, the stop structure 4 overlaps with the air outlet 31 to block the air outlet 31. When the CPU temperature sensor captures that the CPU temperature reaches 65°, the EC sends an instruction to open the air outlet 31 to the fan IC. The fan IC controls the small motor to rotate clockwise through the control line 53 and drives the gear 52 to rotate clockwise, thereby moving the stop structure 4 away from the air outlet 31 and making the air outlet 31 in an open state; when the CPU sensor captures that the CPU temperature is less than 65°, the EC sends an instruction to close the air outlet 31 to the fan IC. The fan IC controls the small motor to rotate counterclockwise through the control line 53 and drives the gear 52 to rotate counterclockwise, thereby blocking the air outlet 31 with the stop structure 4 and making the air outlet 31 in a closed state. It can be understood that 65° in the above temperature is not limited to this temperature and can be adaptively set according to actual needs. When the stop structure 4 coincides with the air outlet 31, since the second surface is a closed surface, even if a plurality of grooves 43 are formed on the first surface, the air blown out by the fan 2 will not pass through the stop structure 4.

[0044] In an implementable embodiment, the driving structure 5 includes a driving member, a rotating shaft 51 connected to the driving member, and a gear 52 sleeved on the rotating shaft 51. The driving member is arranged on the housing 1. The rotating shaft 51 is arranged along a first direction, and a rack is arranged on the stop structure 4. The gear 52 is meshed and connected with the rack.

[0045] In this embodiment, the rack (not shown in the figure) can be adaptively designed according to the movement path of the stop structure 4. The rack is fixed to the stop structure 4, and the rack is driven to move by engaging the gear 52 with the rack, so as to drive the stop structure 4 to move along the extending direction of the side wall 3. It can be understood that the connection manner between the driving structure 5 and the stop structure 4 is not limited to the above manner. The driving structure 5 can also be a cam mechanism or the like, as long as the driving structure 5 can drive the stop structure 4 to move.

[0046] The present disclosure also provides an electronic device (not shown in the figure), including a housing and electronic components disposed inside the housing. The heat dissipation component in any of the above embodiments is further disposed in the housing 1, and the air outlet 31 is disposed corresponding to the electronic components, so that the air blown by the fan 2 can pass through the air outlet 31 and blow towards the electronic components.

[0047] In this embodiment, taking the electronic device as a laptop computer as an example, the housing includes a C shell and a D shell. The electronic components can be any components that generate heat. The air outlet 31 is arranged facing the electronic components to dissipate heat from the electronic components. Since the electronic device is provided with a heat dissipation component, and the air outlet 31 is provided on the side wall 3 of the heat dissipation component, the air of the fan 2 in the accommodation space 30 can be blown out from the air outlet 31 to dissipate heat from the wafer or components. Also, since the heat dissipation component further includes a stop structure 4 and a driving structure 5, the driving structure 5 can control the stop structure 4 to move along the extending direction of the side wall 3. Thus, when the stop structure 4 moves to coincide with the air outlet 31, the stop structure 4 blocks the air outlet 31 to prevent the air of the fan 2 from blowing out from the air outlet 31; when the stop structure 4 moves away from the air outlet 31, the air of the fan 2 can be blown out from the air outlet 31. Therefore, the heat dissipation component can switch the air outlet 31 on and off according to different functional requirements, solves the problem of dust accumulation caused by the continuous opening of the air outlet 31, improves the performance of the electronic device, enhances the heat dissipation efficiency, and can extend the service life of the electronic device. Specifically, when the user runs software with a small load, such as a word processor application program, etc., the driving structure 5 will control the stop structure 4 to keep the air outlet 31 in a closed state; when the user runs software with a large load, such as a game software or a simulation software, etc., the driving structure 5 will control the stop structure 4 to keep the air outlet 31 in a ventilated state to blow the electronic components, the C shell and the D shell, so as to reduce the temperature and improve the user experience.
