Description

Technical Field

[0001] This application relates to the field of terminal device technology, and more particularly to terminal devices. Background Technology

[0002] As the functionality of terminal devices (such as mobile phones) improves, the heat generated by the heat-generating components within these devices also increases. Therefore, it is necessary to dissipate heat from these components and improve their ambient temperature. How to provide a terminal device that can efficiently dissipate heat from its components while minimizing the area occupied by its heat dissipation structure on the inner surface of the device's casing is a challenge that the industry needs to address. Summary of the Invention

[0003] This application provides a terminal device that enables efficient heat dissipation of the heat-generating components of the terminal device, and the heat dissipation structure occupies a small area of ​​the inner plane of the terminal device cover.

[0004] The embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, embodiments of this application provide a terminal device, including a housing, a camera module, a ventilation channel, and a fan. The housing includes a cover and a decorative element, the decorative element being disposed on the cover and having a receiving cavity, an air inlet, and an air outlet. The camera module is disposed within the receiving cavity. The ventilation channel is at least partially disposed within the receiving cavity, and the ventilation channel connects the air inlet and the air outlet. The fan is used to generate airflow within the ventilation channel to dissipate heat from a predetermined heat-generating device disposed on the housing. The fan is disposed at the bottom of the camera module, or the fan is disposed between adjacent camera modules.

[0006] The terminal device provided in this application embodiment has a housing including a cover and a decorative component disposed on the cover. A camera module can be placed inside the decorative component. A ventilation channel is disposed within the receiving cavity of the decorative component, connecting the air inlet and outlet of the decorative component. When the fan operates, it generates airflow within the ventilation channel. The airflow flows along the ventilation channel, dissipating heat generated by predetermined heat-generating components in the housing, achieving efficient active heat dissipation of the predetermined heat-generating components and improving the thermal reliability of the terminal device. The fan can be located at the bottom of the camera module or between adjacent camera modules. As a heat dissipation structure, the fan occupies a small area on the inner surface of the cover, having minimal impact on the internal component layout and appearance design of the terminal device.

[0007] In one alternative implementation, the decorative element and the cover can be an assembled structure or a single piece. The decorative element protrudes from the cover to facilitate the placement of the camera module within the cavity of the decorative element.

[0008] In one alternative implementation, the ventilation duct includes an interconnected air inlet duct and an air outlet duct, with the air inlet duct connected to the air inlet and the air outlet duct connected to the air outlet; the air inlet side of the fan is connected to the air inlet duct, and the air outlet side of the fan is connected to the air outlet duct. The airflow generated when the fan is operating enters through the air inlet, passes through the air inlet duct and the air outlet duct, and is finally discharged through the air outlet.

[0009] In one alternative implementation, the fan, air intake duct, and air exhaust duct are positioned adjacent to the same camera module. By fully utilizing the space around the same camera module and centrally arranging the air intake and exhaust ducts, their lengths can be shortened, reducing pressure loss of the airflow within the ventilation channels. This also reduces the space occupied by the fan, air intake duct, and air exhaust duct at the decorative elements.

[0010] In one alternative implementation, the fan is located at the bottom of the camera module, and the fan and a portion of the air intake channel are stacked on the bottom of the camera module, occupying a small area inside the cover. A predetermined heat-generating device is connected to the air intake channel, and the heat generated by the predetermined heat-generating device is conducted to the air intake channel; alternatively, the predetermined heat-generating device is connected to the fan, and the heat generated by the predetermined heat-generating device is conducted to the fan. The airflow carrying heat flows towards the air outlet channel and exits through the air outlet, achieving air cooling of the predetermined heat-generating device.

[0011] In one alternative implementation, the air intake channel has a first air intake section connected to an air inlet. The air intake channel also has a second air intake section connected to the first air intake section, located between the fan's air inlet side and a predetermined heat-generating device. The air outlet channel has a first air outlet section connected to an air outlet. The first air outlet section and the second air intake section are located on the same side of the camera module, while the second air intake section and the fan are located at the same bottom of the camera module.

[0012] In one alternative implementation, the fan is located at the bottom of the camera module, and the thickness direction of the fan is parallel to the optical axis direction of at least one camera module. This allows for a smaller thickness of the stacked structure formed by the fan and camera module, thus reducing the overall thickness of the terminal device.

[0013] In one alternative implementation, the camera module, fan, and a portion of the air intake channel are arranged sequentially, with the air intake channel connected to a predetermined heat-generating device. This results in a smaller footprint within the cover.

[0014] In one alternative implementation, a thermally conductive layer is provided between the air inlet channel and the predetermined heat-generating device. The thermally conductive layer can reduce thermal resistance and improve the thermal conductivity between the predetermined heat-generating device and the ventilation channel.

[0015] In one alternative implementation, the camera module, a portion of the air intake channel, and the fan are arranged sequentially, with the fan connected to a predetermined heat-generating device. This results in a smaller footprint within the cover.

[0016] In one alternative implementation, a thermally conductive layer is provided between the fan and the intended heat-generating device. This thermally conductive layer reduces thermal resistance and improves the heat conduction between the intended heat-generating device and the fan.

[0017] In one alternative implementation, the predetermined heat-generating device is located at the bottom of the camera module. This reduces the length of the ventilation channel, decreases pressure loss within the ventilation channel, and improves air-cooling efficiency.

[0018] In one alternative implementation, the housing further includes a mid-frame, with a first circuit board disposed on one side of the mid-frame. A predetermined heat-generating device is mounted on the first circuit board, and the predetermined heat-generating device and one of the camera modules are located on opposite sides of the first circuit board. The predetermined heat-generating device can achieve air cooling through ventilation channels and fans located in the decorative element.

[0019] In one alternative implementation, the terminal device further includes a second circuit board, with the first and second circuit boards stacked together. Both the first and second circuit boards can house electronic components, allowing for the placement of more electronic components within a limited space. A fan is located at the bottom of the camera module, and the second circuit board and the fan are arranged adjacent to each other on the plane of the first circuit board. This effectively utilizes the space of the plane containing the first circuit board, and the stacked structure does not increase the overall thickness.

[0020] In one alternative implementation, a third circuit board is also included, which may be disposed within the housing. The first and third circuit boards may be disposed in different areas of the housing. A battery may be disposed between the first and third circuit boards.

[0021] In one alternative implementation, a fan is positioned between adjacent camera modules. The housing includes a first heat-conducting component, comprising a first extension and a second extension connected together. The first extension is connected to a predetermined heat-generating device, and the second extension is located between adjacent camera modules. A fan and a portion of an air inlet channel are stacked between adjacent camera modules, and the second extension is connected to the fan or the air inlet channel. This configuration occupies a relatively small area within the housing. The heat generated by the predetermined heat-generating device is conducted to the first extension and then to the second extension. The heat from the second extension flows along the air outlet channel with the fan's airflow and exits at the air outlet, achieving air cooling for the predetermined heat-generating device.

[0022] In one alternative implementation, the extension directions of the first extension and the second extension are different. The first extension has two opposite ends, and the second extension has two opposite ends. One end of the first extension and one end of the second extension are connected. The heat generated by the predetermined heat-generating device can be guided to a predetermined location, and air cooling of the first heat-conducting component is achieved through a fan between adjacent camera modules, thus dissipating heat from the predetermined heat-generating device.

[0023] In one alternative implementation, the first heat-conducting element is a vacuum chamber heat spreader or a heat-conducting body.

[0024] In one alternative implementation, the fan is positioned between adjacent camera modules, with the fan's thickness direction perpendicular to the optical axis of at least one camera module. This fully utilizes the gap between adjacent camera modules, ensuring the fan does not occupy other space on the cover.

[0025] In one alternative implementation, a thermally conductive layer is provided between the first extension and the predetermined heat-generating device. The thermally conductive layer can reduce thermal resistance and improve the thermal conductivity between the predetermined heat-generating device and the first extension.

[0026] In one alternative implementation, the second extension, the fan, and the air inlet channel are arranged sequentially, with the second extension connected to the fan. This results in a smaller footprint within the cover.

[0027] In one alternative implementation, a heat-conducting layer is provided between the second extension and the fan. The heat-conducting layer can reduce thermal resistance and improve the heat conduction between the second extension and the fan.

[0028] In one alternative implementation, the fan, the air inlet channel, and the second extension are arranged sequentially, with the second extension connected to the air inlet channel. This solution occupies a smaller area inside the cover.

[0029] In one alternative implementation, a heat-conducting layer is provided between the second extension and the air inlet channel. The heat-conducting layer can reduce thermal resistance and improve the heat conduction capacity between the second extension and the air inlet channel.

[0030] In one alternative implementation, the terminal device further includes a second circuit board, with the first and second circuit boards stacked together. Both the first and second circuit boards can accommodate electronic components, allowing for the arrangement of a greater number of electronic components within a limited space.

[0031] In one alternative implementation, a fan is positioned between adjacent camera modules, with one camera module, a second circuit board, and a first circuit board arranged sequentially along the thickness direction of the first circuit board. The second circuit board can be positioned on the back of the camera module, with its area increased to accommodate more electronic components.

[0032] In one alternative implementation, the air intake channel has a first air intake section located between two adjacent camera modules. The cross-sectional length of the first air intake section is parallel to the optical axis of the camera module. By fully utilizing the small gap between adjacent camera modules, the cross-sectional area of ​​the first air intake section is maximized. Combined with a fan, this allows for a large airflow within the first air intake section, which is beneficial for improving heat dissipation.

[0033] In one alternative implementation, the air outlet channel has a first air outlet section located between two adjacent camera modules. The cross-sectional length of the first air outlet section is parallel to the optical axis of the camera module. By fully utilizing the small gap between adjacent camera modules, the cross-sectional area of ​​the first air outlet section is maximized. Combined with a fan, this allows for the generation of a large airflow within the first air outlet section, which is beneficial for improving heat dissipation.

[0034] In one alternative implementation, a second heat-conducting element is provided on the side of the middle frame opposite to the first circuit board. The middle frame has an opening through which a predetermined heat-generating device passes, and the second heat-conducting element is connected to the predetermined heat-generating device. The large-area second heat-conducting element conducts heat from the predetermined heat-generating device to other locations, reducing local hot spots on the predetermined heat-generating device.

[0035] In one alternative implementation, a thermally conductive layer may be provided between the second thermally conductive element and the predetermined heat-generating device to reduce thermal resistance, improve thermal conductivity, and make it easier for the heat from the predetermined heat-generating device to be conducted to the second thermally conductive element, thereby improving the heat dissipation effect.

[0036] In one alternative implementation, the area of ​​the second heat-conducting element is larger than the area of ​​the predetermined heat-generating device. The area of ​​the second heat-conducting element refers to the area of ​​its larger surface area. The heat generated by the predetermined heat-generating device can be diffused through the larger area of ​​the second heat-conducting element, thus improving heat dissipation capacity.

[0037] In one alternative implementation, the decorative element includes a cover plate and a surrounding wall, with the surrounding wall connecting the cover plate and the cover body. The cover plate and the surrounding wall form a receiving cavity within which a camera module and a ventilation channel can be placed. An air inlet may be located on the cover plate and / or the surrounding wall. An air outlet may be located on the cover plate and / or the surrounding wall. A fan operates to generate airflow, which enters the air intake channel through the air inlet, passes through the air outlet channel, and exits through the air outlet.

[0038] In one alternative implementation, the cover plate can be a transparent plate that protects the camera module, allowing the camera module to capture external images through the transparent cover plate. Alternatively, the cover plate may include a plate-like portion and a lens, with the lens located at a hole in the plate-like portion and positioned on the light-incident side of the camera module, thus protecting the camera module while allowing the camera module to capture external images through the lens.

[0039] In one alternative implementation, the orientation of the air outlet forms a predetermined angle with the length direction of the housing. The hot airflow exits through the outlet without blowing directly onto the user's hands, resulting in a better user experience.

[0040] In one alternative implementation, both the air inlet and the air outlet are located on the enclosure of the decorative component. The air inlet is located on the enclosure along the length of the casing, and the air outlet is located on the enclosure along the width of the casing.

[0041] In one alternative implementation, the fan can be a centrifugal fan or a piezoelectric fan. It generates airflow within the ventilation channel, carrying away the heat. Both centrifugal and piezoelectric fans are miniature fans, occupying relatively little space. Attached Figure Description

[0068] See Figure 1In (a) and (b) of the related technology, a terminal device 1 includes a back cover 11, a camera module 12, a ventilation channel 13, and a fan 14. The camera module 12 and its decorative part 12a are located at the upper middle position of the back cover 11. The ventilation channel 13 is located on the inner side of the back cover 11 and extends along the left and right direction of the back cover 11. The opposite ends of the ventilation channel 13 form an air inlet 13a and an air outlet 13b, respectively. The fan 14 is located at the air inlet 13a. A heat-generating device (such as a main chip) may be located at the bottom of the ventilation channel 13 or the bottom of the fan 14.

[0069] See Figure 2 In (a) and (b) of the related technology, another terminal device 2 includes a back cover 21, a camera module 22, a ventilation channel 23, and a fan 24. The camera module 22 and its decorative part 22a are located in the middle of the back cover 21. The ventilation channel 23 is located on the inner side of the back cover 21. The ventilation channel 23 is roughly U-shaped and located near one edge of the back cover 21. A part of the ventilation channel 23 passes through the decorative part 22a. The two ends of the ventilation channel 23 form an air inlet 23a and an air outlet 23b, respectively. Both the air inlet 23a and the air outlet 23b are located on one edge of the back cover 21. A fan 24 is provided at each of the two turning points of the ventilation channel 23. A heat-generating device (such as a main chip) may be located at the bottom of the ventilation channel 23 or the bottom of the fan 24.

[0070] In both of the above terminal device solutions, the fan generates airflow within the ventilation channel when it operates. This airflow moves along the direction from the air inlet to the air outlet, carrying away the heat generated by the heat-generating components and achieving air cooling. However, the fan and camera module are arranged adjacent to each other on the plane of the back cover. As a heat dissipation structure, the fan occupies a large area of ​​the inner plane of the back cover, which has a significant impact on the internal component layout and appearance design of the terminal device.

[0071] The terminal devices provided in this application can be consumer electronics, home electronics, financial terminal products, etc. Consumer electronics can include mobile phones, tablets, laptops, e-readers, personal computers (PCs), personal digital assistants (PDAs), desktop monitors, smart wearable products (such as smartwatches and smart bracelets), virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, drones, etc. Home electronics can include smart door locks, televisions, refrigerators, and small rechargeable household appliances (such as robot vacuum cleaners). Financial terminal products can include automated teller machines (ATMs) and self-service terminals.

[0072] See Figures 3 to 6 This application provides a terminal device 100, including a housing 110, a camera module 120, a ventilation channel 130, and a fan 140. The housing 110 includes a cover 111 and a decorative element 112. The decorative element 112 is disposed on the cover 111 and has a receiving cavity 1121, an air inlet 112a, and an air outlet 112b. The camera module 120 is disposed within the receiving cavity 1121. Figure 7 , Figure 8 In (a) and (b), the ventilation channel 130 is at least partially disposed within the accommodating cavity 1121, and the ventilation channel 130 is used to connect the air inlet 112a and the air outlet 112b. The fan 140 is used to generate airflow within the ventilation channel 130 to dissipate heat from the predetermined heat-generating device 170 disposed on the housing 110. The fan 140 is disposed at the bottom of the camera module 120, or the fan 140 is disposed between adjacent camera modules 120. Figure 7 , Figure 8 The solid arrow on the ventilation duct 130 indicates the airflow direction. Figure 8 The dashed arrows in the diagram indicate the direction of heat conduction.

[0073] The housing 110 serves as a carrier for various components, and can house a screen 191, a battery 192, a circuit board, an earpiece, a speaker, a camera module 120, and / or other components. There can be one or more camera modules 120. In cases where there are multiple camera modules 120 and the fan 140 is located at the bottom of any one of the camera modules 120, the fan 140 can be located at the bottom of any one of the camera modules 120.

[0074] Decorative element 112 is a decorative component surrounding the lens of camera module 120, used to enhance the appearance and protect the lens. The intended heat-generating device 170 may be a system-on-chip (SOC) or similar device, which generates significant heat during operation.

[0075] Combination Figure 7 The ventilation duct 130 may have an inlet 131a and an outlet 132b, with the inlet 131a correspondingly connected to the air inlet 112a of the decorative element 112, and the outlet 132b correspondingly connected to the outlet 132b of the decorative element 112. The ventilation duct 130 connects the air inlet 112a and the air outlet 112b.

[0076] The terminal device 100 provided in this application embodiment has a housing 110 including a cover 111 and a decorative element 112 disposed on the cover 111. A camera module 120 can be placed inside the decorative element 112. A ventilation channel 130 is disposed within the receiving cavity 1121 of the decorative element 112, allowing the air inlet 112a and air outlet 112b of the decorative element 112 to communicate. When the fan 140 is working, it generates airflow within the ventilation channel 130. The airflow flows along the ventilation channel 130, dissipating heat generated by the predetermined heat-generating device 170 of the housing 110, achieving efficient active heat dissipation of the predetermined heat-generating device 170 and improving the thermal reliability of the terminal device 100. The fan 140 can be located at the bottom of the camera module 120 or between adjacent camera modules 120. As a heat dissipation structure, the fan 140 occupies a small area on the inner plane of the cover 111, having minimal impact on the internal component layout and appearance design of the terminal device 100.

[0077] When the terminal device is 100% in the form of a mobile phone or tablet computer, please refer to Figure 4 The cover 111 can serve as a back cover or a back shell. The camera module 120 disposed on the cover 111 can serve as a rear camera module, which can capture images of the scene in front of the user when the user holds the terminal device 100. The cover 111 can be rectangular or rounded rectangular in shape.

[0078] When setting the cover 111 and the decorative element 112, refer to Figure 4 , Figure 5 The decorative element 112 and the cover 111 can be an assembled structure or a one-piece structure. Figure 6 , Figure 7 The decorative element 112 protrudes from the cover 111, facilitating the arrangement of the camera module 120 within the receiving cavity 1121 of the decorative element 112. The shape of the decorative element 112 can be determined according to the number and arrangement of the camera modules 120.

[0079] For example, the cover 111 has four camera modules 120 arranged in an array, and the decorative piece 112 can be circular in shape. The lenses of the four camera modules 120 are located within the circular decorative piece 112. The four camera modules 120 can be a main camera, a wide-angle camera, a telephoto camera, and a macro camera, respectively.

[0080] For example, the cover 111 has three camera modules 120 arranged in an array, and the large surface of the decorative piece 112 can be a rounded triangle. The lenses of the three camera modules 120 are respectively located at the three corners of the rounded triangle decorative piece 112. The three camera modules 120 can be a main camera, a wide-angle camera, and a telephoto camera, respectively.

[0081] When setting up ventilation duct 130 and fan 140, refer to Figure 7 , Figure 9 , Figure 10 In (a) and (b), ventilation duct 130 includes an air inlet duct 131 and an air outlet duct 132 that are connected to each other. Air inlet duct 131 is connected to air inlet 112a, and air outlet duct 132 is connected to air outlet 112b. The air inlet side 140a of fan 140 is connected to air inlet duct 131, and the air outlet side 140b of fan 140 is connected to air outlet duct 132. Figure 9 , Figure 10 The solid arrow on the ventilation duct 130 indicates the airflow direction. The inlet 131a of the ventilation duct 130 is on the air intake duct 131, and the outlet 132b is on the air outlet duct 132. The air intake duct 131 also has an outlet 131b communicating with the inlet 131a, and the air outlet duct 132 also has an inlet 132a communicating with the outlet 132b. The outlet 131b of the air intake duct 131 is connected to the air intake side 140a of the fan 140, and the inlet 132a of the air outlet duct 132 is connected to the air outlet side 140b of the fan 140.

[0082] When the fan 140 is working, the airflow enters through the air inlet 112a, passes through the air inlet channel 131 and the air outlet channel 132, and is finally discharged through the air outlet 112b. The air inlet channel 131 and the air outlet channel 132 can be manufactured separately and assembled with the fan 140, or they can be an integral structure assembled with the fan 140. The air inlet channel 131 and the air outlet channel 132 are connected. They can be directly connected, or the fan 140 can be installed between the air inlet channel 131 and the air outlet channel 132, and the connection can be indirectly achieved through the internal cavity of the fan 140.

[0083] To minimize the space occupied by the ventilation duct 130 and the fan 140, in some embodiments, see [reference]. Figures 7 to 10The fan 140, air inlet channel 131, and air outlet channel 132 are arranged adjacent to the same camera module 120. By making full use of the space around the same camera module 120, the air inlet channel 131 and air outlet channel 132 are arranged in a concentrated manner, allowing the air inlet channel 131 and air outlet channel 132 to be made smaller and shorter, thus reducing the pressure loss of airflow within the ventilation channel 130. This reduces the space occupied by the fan 140, air inlet channel 131, and air outlet channel 132 at the decorative component 112, making it easier to reserve more space within the decorative component 112 for installing other camera modules 120 or other devices.

[0084] In some embodiments, see Figure 8 In (a) and (b), the fan 140 is located at the bottom of the camera module 120, and the fan 140 and a portion of the air inlet channel 131 are stacked on the bottom of the camera module 120. This design occupies a smaller area inside the cover 111. When the fan 140 is working, the airflow generated flows from the air inlet side 140a to the air outlet side 140b, and the airflow flows along the air inlet 112a, air inlet channel 131, air outlet channel 132, and air outlet 112b of the decorative piece 112. The predetermined heat-generating device 170 is connected to the air inlet channel 131, and the heat generated by the predetermined heat-generating device 170 is conducted to the air inlet channel 131; or, the predetermined heat-generating device 170 is connected to the fan 140, and the heat generated by the predetermined heat-generating device 170 is conducted to the fan 140. The airflow carrying heat flows towards the air outlet channel 132 and flows out from the air outlet 112b, realizing the air cooling of the predetermined heat-generating device 170. The connection between two structural components can be either a direct connection or an indirect connection through other structural components.

[0085] For example, see Figures 7 to 10The air inlet channel 131 has a first air inlet section 1311, which communicates with the air inlet 112a. The air inlet channel 131 also has a second air inlet section 1312, which communicates with the first air inlet section 1311 and is located between the air inlet side 140a of the fan 140 and the predetermined heating element 170. The air outlet channel 132 has a first air outlet section 1321, which communicates with the air outlet 112b. The first air inlet section 1311 and the first air outlet section 1321 can be arranged in an L-shape. The first air outlet section 1321 and the first air outlet section 1321 are located on the side of the same camera module 120, and the second air inlet section 1312 and the fan 140 are located at the bottom of the same camera module 120. This arrangement ensures that the fan 140, the air inlet channel 131, and the air outlet channel 132 are adjacent to the same camera module 120, thus occupying less internal space in the decorative component 112. When the fan 140 is working, the airflow enters through the air inlet 112a, passes through the first air inlet section 1311 and the second air inlet section 1312 in sequence, enters the fan 140, passes through the first air outlet section 1321, and is finally discharged through the air outlet 112b.

[0086] In some embodiments, when fan 140 is configured, refer to Figure 8 In (a) and (b), the fan 140 can be positioned at the bottom of the camera module 120, with the thickness direction D4 of the fan 140 parallel to the optical axis direction 120a of at least one camera module 120. This allows for a smaller thickness of the stacked structure formed by the fan 140 and the camera module 120, thus reducing the overall thickness of the terminal device 100. It also prevents the fan 140 from occupying other space inside the cover 111, allowing for more space inside the cover 111 to accommodate other components. The thickness direction D4 of the fan 140 is typically smaller than its length and width dimensions.

[0087] When the fan 140 is located at the bottom of the camera module 120 and the fan 140 and the air intake channel 131 are stacked, there are several possible implementation methods. Two implementation methods are given as examples below.

[0088] The first implementation method of stacking fan 140 and air inlet channel 131: see [link / reference] Figure 8 In (a) and (b), the camera module 120, fan 140, and a portion of the air inlet channel 131 are arranged sequentially, with the air inlet channel 131 connected to the predetermined heating device 170. This design occupies a relatively small area inside the cover 111. The heat generated by the predetermined heating device 170 is conducted to the air inlet channel 131, and the airflow generated by the fan 140 flows from the air inlet channel 131 to the air outlet channel 132, where the heated airflow is discharged.

[0089] In some embodiments, a thermally conductive layer is provided between the air inlet channel 131 and the predetermined heat-generating device 170. The thermally conductive layer serves as a passive heat dissipation method. It reduces thermal resistance and enhances the thermal conductivity between the predetermined heat-generating device 170 and the air inlet channel 130, allowing heat to be easily conducted from the predetermined heat-generating device 170 to the air inlet channel 131. Combined with the air inlet channel 130 and the fan 140, efficient heat dissipation of the predetermined heat-generating device 170 can be achieved. The thermally conductive layer can be a layer structure made of thermally conductive materials such as thermally conductive gel.

[0090] For example, see Figure 8 In (a) and (b) of the diagram, the predetermined heat-generating device 170 is located on the side of the first circuit board 181 away from the fan 140. The heat generated by the predetermined heat-generating device 170 is conducted to the fan 140 through the first circuit board 181. A heat-conducting layer is provided between the position of the first circuit board 181 opposite to the predetermined heat-generating device 170 and the air inlet channel 131, which can reduce thermal resistance and improve heat dissipation efficiency.

[0091] For example, a predetermined heat-generating device 170 is disposed on the side of the first circuit board 181 facing the fan 140. The heat generated by the predetermined heat-generating device 170 is directly conducted to the air inlet channel 131. A thermally conductive layer is disposed between the predetermined heat-generating device 170 and the air inlet channel 131, which can reduce thermal resistance and improve heat dissipation efficiency.

[0092] The second implementation involves stacking the fan 140 and the air inlet channel 131: the camera module 120, a portion of the air inlet channel 131, and the fan 140 are arranged sequentially, with the fan 140 connected to a predetermined heating device 170. This solution occupies a smaller area inside the cover 111. The heat generated by the predetermined heating device 170 is conducted to the fan 140, and the airflow generated by the fan 140 flows from the air inlet channel 131 to the air outlet channel 132, where the heated airflow is discharged.

[0093] In some embodiments, a thermally conductive layer is provided between the fan 140 and the predetermined heat-generating device 170. The thermally conductive layer serves as a passive heat dissipation method. The thermally conductive layer can reduce thermal resistance and improve the thermal conductivity between the predetermined heat-generating device 170 and the fan 140, making it easier for heat to be conducted from the predetermined heat-generating device 170 to the fan 140. Combined with the ventilation channel 130 and the fan 140, efficient heat dissipation of the predetermined heat-generating device 170 can be achieved.

[0094] When setting the position of the predetermined heating element 170, refer to Figure 8 (a) and (b) in Figure 9The predetermined heat-generating device 170 is located at the bottom of the camera module 120. This reduces the extension length of the ventilation channel 130, decreases the pressure loss of the airflow within the ventilation channel 130, and allows the airflow generated by the fan 140 to flow more quickly along the ventilation channel 130, thereby dissipating the heat from the predetermined heat-generating device 170, reducing the impact of heat on surrounding devices, and improving air-cooling efficiency. The predetermined heat-generating device 170 and the bottom of the camera module 120 can be positioned directly opposite each other or offset.

[0095] In some embodiments, see Figure 5 , Figure 8 In (a) and (b) of the diagram, the housing 110 also includes a middle frame 113. A first circuit board 181 is provided on one side of the middle frame 113. A predetermined heat-generating device 170 is disposed on the first circuit board 181. The predetermined heat-generating device 170 and one of the camera modules 120 are respectively located on opposite sides of the first circuit board 181. The predetermined heat-generating device 170 can achieve air cooling through the ventilation channel 130 and the fan 140 located on the decorative part 112. The side of the predetermined heat-generating device 170 away from the first circuit board 181 can achieve heat dissipation through other means. The predetermined heat-generating device 170 may be a heat-generating device such as a main chip disposed on the first circuit board 181.

[0096] The middle frame 113 may include a plate 1131 and a frame 1132, with the frame 1132 located at the edge of the plate 1131. The middle frame 113 can serve as a carrier for devices such as the screen 191 and the battery 192. The cover 111 may be located on one side of the middle frame 113, and the screen 191 may be located on the other side of the middle frame 113. The cover 111 and the middle frame 113 can be an assembled structure or an integrated structure. The cover 111 can be assembled onto the middle frame 113 by means of snap-fit ​​or adhesive. The screen 191 can be adhesively attached to the middle frame 113.

[0097] Screen 191 is used to output light to display images and information. Screen 191 can be an organic light-emitting diode (OLED) screen or an active matrix organic light-emitting diode (AMOLED) screen.

[0098] In some embodiments, see Figure 5 , Figure 8 (a) Figure 9 The terminal device 100 also includes a second circuit board 182, with the first circuit board 181 and the second circuit board 182 stacked together. Both the first circuit board 181 and the second circuit board 182 can accommodate electronic components, allowing for the arrangement of a greater number of electronic components within a limited space. Combined with... Figure 11A frame-shaped adapter plate 183 can be stacked between the first circuit board 181 and the second circuit board 182, so that the first circuit board 181 and the second circuit board 182 are stacked and electrically connected.

[0099] See Figure 8 (a) Figure 9 The fan 140 is located at the bottom of the camera module 120, and the second circuit board 182 and the fan 140 are arranged adjacent to each other on the plane of the first circuit board 181. The fan 140 is not stacked with the second circuit board 182, but is located at the bottom of the camera module 120, which effectively utilizes the space of the plane of the first circuit board 181, so that the stacked structure formed by the camera module 120, the fan 140 and a part of the air inlet channel 131 (the second air inlet section 1312) does not increase the overall thickness.

[0100] In some embodiments, see Figure 5 , Figure 6 It also includes a third circuit board 184, which can be disposed within the housing 110. The first circuit board 181 and the third circuit board 184 can be disposed in different areas of the housing 110. A battery 192 can be disposed between the first circuit board 181 and the third circuit board 184.

[0101] In some embodiments, see Figures 12 to 17 The fan 140 is disposed between adjacent camera modules 120. The housing 110 is provided with a first heat-conducting element 150. The first heat-conducting element 150 includes a first extension 151 and a second extension 152 connected to each other. The first extension 151 is connected to a predetermined heat-generating device 170, and the second extension 152 is located between adjacent camera modules 120. The fan 140 and a portion of the air inlet channel 131 are stacked between adjacent camera modules 120, and the second extension 152 is connected to the fan 140 or the air inlet channel 131. Figures 15 to 17 The solid arrow on the ventilation duct 130 indicates the airflow direction. Figure 16 The dashed arrows in the diagram indicate the direction of heat conduction. The connection between two structural components can be direct or indirect, with other structural components between them.

[0102] This design occupies a relatively small area inside the cover 111. The heat generated by the predetermined heating element 170 is conducted to the first extension 151, and then to the second extension 152. When the fan 140 is working, the airflow generated flows from the air inlet side 140a to the air outlet side 140b, along the air inlet 112a of the decorative element 112, the air inlet channel 131 and the air outlet channel 132 of the ventilation channel 130, and the air outlet 112b of the decorative element 112. The heat in the second extension 152 flows along the air outlet channel 132 with the airflow from the fan 140 and exits at the air outlet 112b, indirectly achieving air cooling of the predetermined heating element 170.

[0103] For example, the air inlet channel 131 has a first air inlet section 1311, which is connected to the air inlet 112a. The air outlet channel 132 has a first air outlet section 1321, which is connected to the air outlet 112b. The fan 140 and the first air inlet section 1311 are stacked on the side of the same camera module 120. The first air inlet section 1311 and the first air outlet section 1321 can be arranged in an L-shape and are located on the outer periphery of the same camera module 120. This makes the fan 140, the air inlet channel 131, and the air outlet channel 132 adjacent to the same camera module 120, occupying less internal space in the decorative part 112. When the fan 140 is working, the airflow enters through the air inlet 112a, passes through the first air inlet section 1311 into the fan 140, and passes through the first air outlet section 1321 and is discharged through the air outlet 112b.

[0104] When setting the shape of the first heat-conducting element 150, refer to Figures 15 to 19 The extension directions D51 of the first extension 151 and D52 of the second extension 152 are different. The first extension 151 has two opposite ends, and the second extension 152 has two opposite ends. One end of the first extension 151 and one end of the second extension 152 are connected. The two opposite ends of the first extension 151 are located on the extension direction D51 of the first extension 151. The two opposite ends of the second extension 152 are located on the extension direction D52 of the second extension 152. The first heat-conducting element 150 is bent and extended as a three-dimensional structure, which can guide the heat from the operation of the predetermined heat-generating device 170 to a predetermined position. The fan 140 between adjacent camera modules 120 realizes air cooling of the first heat-conducting element 150, thereby realizing heat dissipation of the predetermined heat-generating device 170.

[0105] When the first heat-conducting element 150 is configured, it can be a vacuum chamber heat spreader or a heat conductor. The specific configuration is determined as needed.

[0106] A vapor chamber (VC) is a vacuum chamber with a microstructured inner wall, containing an evaporation zone and a condensation zone. The vacuum chamber is filled with water or other cooling media. When heat is conducted to the evaporation zone, the liquid cooling media in the chamber vaporizes upon heating, rapidly expanding in volume as it absorbs heat, quickly filling the entire chamber. When the vapor cooling media comes into contact with the cooler condensation zone, it condenses, releasing the heat accumulated during evaporation. The condensed liquid cooling media returns to the evaporation zone through capillary channels in the microstructure. This process continuously cycles, transferring heat from the evaporation zone to the condensation zone. Airflow from fan 140 dissipates the heat from the evaporation zone of the vapor chamber.

[0107] The heat conductor can be a structure made of thermally conductive metal materials such as copper. The heat of the heat conductor is dissipated by the airflow of fan 140.

[0108] In some embodiments, when fan 140 is configured, refer to... Figure 16 In (a) and (b), the fan 140 can be positioned between adjacent camera modules 120, with the thickness direction D4 of the fan 140 perpendicular to the optical axis direction 120a of at least one camera module 120. This fully utilizes the gap between adjacent camera modules 120, ensuring the fan 140 does not occupy other space on the cover 111, thus minimizing its impact on the internal component layout and appearance design of the terminal device 100. The thickness direction D4 of the fan 140 is typically smaller than its length and width dimensions.

[0109] In some embodiments, see Figure 16 In (a) and (b) of the diagram, a thermally conductive layer 151b is provided between the first extension 151 and the predetermined heat-generating device 170. The thermally conductive layer 151b serves as a passive heat dissipation method. The thermally conductive layer 151b can reduce thermal resistance and improve the thermal conductivity between the predetermined heat-generating device 170 and the first extension 151, making it easier for heat to be conducted from the predetermined heat-generating device 170 to the first extension 151. The thermally conductive layer 151b can be a layer structure made of thermally conductive materials such as thermally conductive gel.

[0110] When the fan 140 is located between adjacent camera modules 120 and the fan 140 and the air intake channel 131 are stacked, there are several possible implementation methods. Two implementation methods are given below as examples.

[0111] The first implementation method of stacking fan 140 and air inlet channel 131: see [link / reference] Figure 16In (a) and (b), the second extension 152, the fan 140, and the air inlet channel 131 are arranged sequentially, with the second extension 152 connected to the fan 140. This design occupies a relatively small area inside the cover 111. The heat generated by the predetermined heating element 170 is conducted to the fan 140 through the first heat-conducting element 150. The airflow generated by the fan 140 flows from the air inlet channel 131 to the air outlet channel 132, and the heated airflow is discharged through the air outlet channel 132.

[0112] In some embodiments, a heat-conducting layer is provided between the second extension 152 and the fan 140. The heat-conducting layer serves as a passive heat dissipation method. The heat-conducting layer can reduce thermal resistance and improve the heat conduction capacity between the second extension 152 and the fan 140, making it easier for heat to be conducted from the second extension 152 to the fan 140.

[0113] The second implementation involves stacking the fan 140 and the air inlet channel 131: the fan 140, the air inlet channel 131, and the second extension 152 are arranged sequentially, with the second extension 152 connected to the air inlet channel 131. This solution occupies a smaller area inside the cover 111. The heat generated by the predetermined heating element 170 is conducted to the air inlet channel 131 via the first heat-conducting element 150. The airflow generated by the fan 140 flows from the air inlet channel 131 to the air outlet channel 132, and the heated airflow is discharged through the air outlet channel 132.

[0114] In some embodiments, a heat-conducting layer is provided between the second extension 152 and the air inlet channel 131. The heat-conducting layer serves as a passive heat dissipation method. The heat-conducting layer can reduce thermal resistance and improve the thermal conductivity between the second extension 152 and the air inlet channel 131, making it easier for heat to be conducted from the second extension 152 to the air inlet channel 131.

[0115] In some embodiments, see Figure 13 , Figure 16 (a) and (b) in Figure 17 The terminal device 100 also includes a second circuit board 182, with the first circuit board 181 and the second circuit board 182 stacked together. Both the first circuit board 181 and the second circuit board 182 can accommodate electronic components, allowing for the arrangement of a greater number of electronic components within a limited space. Combined with... Figure 20 A frame-shaped adapter plate 183 can be stacked between the first circuit board 181 and the second circuit board 182, so that the first circuit board 181 and the second circuit board 182 are stacked and electrically connected.

[0116] See Figure 16In (a) and (b), the fan 140 is located between adjacent camera modules 120. One of the camera modules 120, the second circuit board 182, and the first circuit board 181 are arranged sequentially along the thickness direction D8 of the first circuit board 181. The second circuit board 182 can be arranged on the back of the camera module 120. The area of ​​the second circuit board 182 is made larger to accommodate more electronic components.

[0117] For example, the predetermined heat-generating device 170 may be disposed on the side of the first circuit board 181 away from one of the camera modules 120, or on the side of the first circuit board 181 facing one of the camera modules 120. The heat generated by the bending and extending first heat-conducting member 150 is directed to the space between adjacent camera modules 120, and the airflow generated by the fan 140 exhausts the heat along the air outlet channel 132, thereby achieving heat dissipation of the predetermined heat-generating device 170.

[0118] In order to minimize the space occupied by the air intake duct 131, in some embodiments, see [reference] Figure 9 , Figure 10 (a) and (b) in Figure 17 , Figure 19 In (a) and (b), the air intake channel 131 has a first air intake section 1311, which is located between two adjacent camera modules 120, combined with Figure 8 (a) Figure 16 In (a), the cross-sectional length direction D31 of the first air inlet section 1311 is parallel to the optical axis direction 120a of the camera module 120. The cross-section of the first air inlet section 1311 refers to the cross-section obtained by cutting the first air inlet section 1311 with a vertical plane along the extension direction of the first air inlet section 1311, and it can be rectangular or other shapes.

[0119] The length direction D31 of the first air intake section 1311 is set to be parallel to the optical axis direction 120a of the camera module 120. This fully utilizes the small gap between adjacent camera modules 120, maximizing the cross-sectional area of ​​the first air intake section 1311. Combined with the fan 140, this allows for the generation of a large airflow within the first air intake section 1311, which is beneficial for improving heat dissipation. The length direction D31 of the first air intake section 1311 is typically larger than the width direction of the first air intake section 1311.

[0120] In order to minimize the space occupied by the air outlet duct 132, in some embodiments, see [reference] Figure 8 (b) Figure 16In (b), the air outlet channel 132 has a first air outlet section 1321, which is located between two adjacent camera modules 120. The cross-sectional length direction D32 of the first air outlet section 1321 is parallel to the optical axis direction 120a of the camera module 120. The cross-section of the first air outlet section 1321 refers to the cross-section obtained by cutting the first air outlet section 1321 with a plane perpendicular to the extension direction of the first air outlet section 1321, and it can be rectangular or other shapes.

[0121] The length direction D32 of the first air outlet section 1321 is set to be parallel to the optical axis direction 120a of the camera module 120. This fully utilizes the small gap between adjacent camera modules 120, maximizing the cross-sectional area of ​​the first air outlet section 1321. Combined with the fan 140, this allows for the generation of a large airflow within the first air outlet section 1321, which is beneficial for improving heat dissipation. The length direction D32 of the first air outlet section 1321 is typically larger than the width direction of the first air outlet section 1321.

[0122] To improve the heat dissipation effect of the predetermined heat-generating device 170, in some embodiments, see [reference]. Figure 5 , Figure 8 (a) and (b) in Figure 13 , Figure 16 In (a) and (b), the middle frame 113 is provided with a second heat-conducting element 160 on the side opposite to the first circuit board 181. The middle frame 113 has an opening 1133, and a predetermined heating device 170 passes through the opening 1133. The second heat-conducting element 160 and the predetermined heating device 170 are connected.

[0123] The second heat-conducting element 160 serves as a passive heat dissipation method. The second heat-conducting element 160 can be configured with a large area. By using the large-area second heat-conducting element 160, heat from the predetermined heat-generating device 170 is conducted to other locations, reducing localized hot spots on the predetermined heat-generating device 170 and improving the thermal reliability of the terminal device 100. The second heat-conducting element 160 can be a vapor chamber heat sink.

[0124] In some embodiments, see Figure 8 (a) and (b) in Figure 16 In (a) and (b), a heat-conducting layer 160a may be provided between the second heat-conducting element 160 and the predetermined heat-generating device 170 to reduce thermal resistance, improve heat conduction capacity, and make it easier for the heat from the predetermined heat-generating device 170 to be conducted to the second heat-conducting element 160, thereby improving the heat dissipation effect.

[0125] In some embodiments, see Figure 6 , Figure 14The area of ​​the second heat-conducting element 160 is larger than the area of ​​the predetermined heat-generating device 170. The area of ​​the second heat-conducting element 160 refers to the area of ​​its large surface. The area of ​​the predetermined heat-generating device 170 also refers to the area of ​​its large surface. This allows the heat generated by the predetermined heat-generating device to be diffused through the large area of ​​the second heat-conducting element, improving heat dissipation capacity.

[0126] When setting decorative element 112, refer to Figures 4 to 7 The decorative element 112 includes a cover plate 1122 and a surrounding wall 1123, with the surrounding wall 1123 connecting the cover plate 1122 and the cover body 111. The cover plate 1122 and the surrounding wall 1123 form a receiving cavity 1121, within which a camera module 120 and a ventilation channel 130 can be placed. An air inlet 112a may be located on the cover plate 1122 and / or the surrounding wall 1123. An air outlet 112b may be located on the cover plate 1122 and / or the surrounding wall 1123. A fan 140 generates airflow, which enters the air intake channel 131 through the air inlet 112a, passes through the air outlet channel 132, and exits through the air outlet 112b. The number of air inlets 112a and the number of air outlets 112b can be one or more.

[0127] When the cover plate 1122 is provided, the cover plate 1122 can be a transparent plate. The cover plate 1122 can protect the camera module 120, and the camera module 120 can capture external scenes through the transparent cover plate 1122. Alternatively, the cover plate 1122 may include a plate-shaped part and a lens. The lens is disposed in a hole in the plate-shaped part and is located on the light-incident side of the camera module 120, thereby protecting the camera module 120 and allowing the camera module 120 to capture external scenes through the lens.

[0128] In some embodiments, see Figure 4 The orientation of the air outlet 112b forms a predetermined angle with the length direction D11 of the housing 110. The orientation of the air outlet 112b is the normal direction of the air outlet 112b and also the airflow direction at the air outlet 112b.

[0129] The predetermined heating element 170 generates heat during operation. The airflow generated by the fan 140 flows within the ventilation channel 130, carrying away the heat from the predetermined heating element 170. The hot airflow is then blown out from the air outlet 112b. The end of the housing 110 along its length D11 is typically where the user operates the terminal device 100, such as when holding one end of the housing 110 with one hand or holding both ends of the housing 110 along its length D11 with both hands. In these scenarios, the hot airflow does not blow directly onto the user's hands, resulting in a better user experience.

[0130] For example, both the air inlet 112a and the air outlet 112b are provided on the enclosure 1123 of the decorative member 112. The air inlet 112a is located at the position of the enclosure 1123 along the length direction D11 of the housing 110, and the air outlet 112b is located at the position of the enclosure 1123 along the width direction D12 of the housing 110.

[0131] When fan 140 is installed, fan 140 can be a centrifugal fan or a piezoelectric fan. Both can generate airflow within the ventilation channel 130 to carry away the heat. Both centrifugal fans and piezoelectric fans are miniature fans and occupy little space.

[0132] The centrifugal fan generates centrifugal force by driving the impeller to rotate rapidly through a motor. This force draws air into the impeller and then discharges it. The air inlet side 140a of the centrifugal fan is located on one axial side of the centrifugal impeller, and the air outlet side 140b is located tangentially around the centrifugal impeller.

[0133] A piezoelectric fan works by using an alternating electric field to cause piezoelectric materials to expand and contract, generating high-frequency resonance that drives an oscillator to do work, thus producing a micro-airflow. Piezoelectric fans are characterized by low energy consumption, low noise, and long lifespan. They also enable imperceptible active cooling.

[0134] When confirming whether it is the terminal device 100 of this embodiment, it can be confirmed by disassembly analysis that the ventilation channel 130 is located in the accommodating cavity 1121 of the decorative part 112. The ventilation channel 130 is used to connect the air inlet 112a and the air outlet 112b of the decorative part 112. The fan 140 is located at the bottom of the camera module 120, or the fan 140 is located between adjacent camera modules 120.

[0135] Finally, it should be noted that the above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
