[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the description of this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0037] See Figures 1-6 This application provides an electronic device including a display component 600, a heat-generating component 100, and a heat dissipation component. The area between the heat-generating component 100 and the display component 600 is a target area. The heat dissipation component has an air outlet component 310 and a target body 320. The air outlet component 310 is located on the side of the heat-generating component 100 facing away from the target area and has a first air outlet. The target body 320 has a channel 321, one end of which is connected to the first air outlet, and the other end is connected to the target area. The electronic device can be of various types, such as a handheld device, tablet computer, laptop computer, mobile phone, or monitor, and this application does not limit this type. The display component 600 is used to output display content; that is, the display component 600 has a display screen. The heat-generating component 100 is a component that generates heat during operation; that is, the heat-generating component 100 in the working state has a need for heat dissipation. The heat dissipation component is used to dissipate heat from the electronic device, thereby reducing the impact of temperature factors on the operational stability of the electronic device and the user experience.

[0038] The heat-generating component 100 is located inside the electronic device, separated from the back of the display component 600 (i.e., the side facing away from the display surface) by a target area. The heat dissipation component has an air outlet component 310, which is located on the side of the heat-generating component 100 facing away from the target area. That is, the display component 600, the heat-generating component 100, and the air outlet component 310 are stacked sequentially. In this way, the combined projected area of ​​the air outlet component 310 and the heat-generating component 100 on the surface of the display component 600 is smaller, thereby leaving more space on the back of the display component 600 for other components (such as the battery module 500 described later). At the same time, the heat dissipation component has a target body 320, which has a channel 321. One end of the channel 321 is connected to the first air outlet of the air outlet component 310 (located in...). Figure 2 At position B in the diagram, the other end connects to the target area between the heat-generating component 100 and the display module 600. This allows at least a portion of the airflow from the air outlet component 310 to be blown into this target area to simultaneously dissipate heat from both the heat-generating component 100 and the display module 600. This helps prevent localized high temperatures in the heat-generating component 100 and reduces the temperature of the display module, resulting in better overall heat dissipation. In summary, the electronic device of this application achieves a compact heat dissipation layout to leave more space for other components while mitigating the adverse effects of a compact layout on overall heat dissipation.

[0039] The heat-generating component 100 can be of various types, such as a motherboard or a discrete graphics card. In this specification, the heat-generating component 100 is represented as a motherboard in the accompanying drawings. In some embodiments, the heat-generating component 100 may be provided with a ventilation hole 101 that passes through the heat-generating component 100. The ventilation hole 101 connects to the end of the channel 321 of the target body 320 away from the first air outlet of the air outlet assembly 310. The air blown out from the first air outlet of the air outlet assembly 310 travels along the channel 321 of the target body 320 to the ventilation hole 101 of the heat-generating component 100, and then enters the area between the heat-generating component 100 and the display assembly 600, i.e., the aforementioned target area, thereby simultaneously dissipating heat from both the heat-generating component 100 and the display assembly 600. The air outlet assembly 310 is located on the side of the heating element 100 facing away from the target area. The air blown out from the first air outlet of the air outlet assembly 310 needs to enter the target area through the channel 321 of the target body 320. A ventilation hole 101 is provided on the heating element 100, extending from the side of the heating element 100 facing the air outlet assembly 310 to the side of the heating element 100 facing the target area. In this way, the channel 321 of the target body 320 delivers air to the ventilation hole 101 of the heating element 100, thus achieving the purpose of delivering air to the target area. In this way, it is not necessary to arrange the target body 320 around the side of the heating element 100 in order to deliver air to the target area. That is, the orthogonal projection of the target body 320 onto the heating element 100 does not occupy the outer side of the heating element 100, thereby further saving the arrangement space of other components around the heating element 100. It should be understood that the aforementioned target area is not a closed area. Therefore, the air from the channel 321 of the target body 320 will eventually leave the target area carrying heat after entering the target area.

[0040] The position of the ventilation hole 101 on the heating element 100 can be set as needed, such as... Figure 1 As shown, in some embodiments, the ventilation hole 101 can be configured as a notch located on the side of the heating element 100. This configuration makes the area on the heating element 100 used for arranging devices more continuous, reducing the adverse effects of the ventilation hole 101 on device arrangement. It should be noted that when the ventilation hole 101 is configured as a notch, the cross-sectional profile of the ventilation hole 101 is not closed, that is, the side of the heating element 100 is cut off at the ventilation hole 101. In order to deliver the air into the target area more smoothly, there needs to be other entities at the location where the side of the heating element 100 is cut off to prevent the air from running away before entering the target area. These other entities are not part of the heating element 100, but can be a part of the target body 320, a part of other components around the heating element 100, etc.

[0041] In some embodiments, the display assembly 600 may include a display screen and a driver board 610 electrically connected to the display screen. The ventilation hole 101 and the driver board 610 may be configured such that their orthographic projections onto the display screen overlap or are adjacent. The driver board 610 is a component used to control and drive the display screen. During the operation of the display assembly 600, the driver board 610 generates more heat than other parts of the display assembly 600. Therefore, it is beneficial for the display assembly 600 to achieve better heat dissipation by preferentially cooling the area near the driver board 610 after the airflow enters the target area. Both the driver board 610 and the heat-generating component 100 are located on the back side of the display screen. Since the orthographic projections of the ventilation hole 101 and the driver board 610 onto the display screen overlap or are adjacent, the airflow first reaches the area near the driver board 610 when entering the target area. It should be noted that when the orthographic projections of the ventilation hole 101 and the driver board 610 onto the display screen overlap, the orthographic projection of the ventilation hole 101 may be entirely within the orthographic projection of the driver board 610, or it may be partially within the orthographic projection of the driver board 610. The adjacency of the orthographic projection of the vent 101 and the drive board 610 onto the display screen means that the orthographic projection of the vent 101 is outside the orthographic projection of the drive board 610, but the distance between them is small (e.g., no more than 5 mm).

[0042] In some embodiments, the air outlet assembly 310 may include a housing 312 and a fan located within the housing 312. The side of the housing 312 facing the heat-generating component 100 may be configured to be thermally connected to a target heat source component mounted on the heat-generating component 100. The target heat source component includes at least a central processing unit 102. A heat source component is a device on the heat-generating component 100 that generates heat. To improve the overall heat dissipation effect on the heat-generating component 100, a heat source component with relatively high heat generation can be arranged in the area corresponding to the orthographic projection of the housing 312 of the air outlet assembly 310 onto the heat-generating component 100, and the heat source component is thermally connected to the housing 312 of the air outlet assembly 310. In this way, the heat from the heat source component can be rapidly diffused to a larger area using the housing 312 of the air outlet assembly 310, improving heat dissipation efficiency. The central processing unit 102 generates relatively high heat during operation. Therefore, the central processing unit 102 can be configured as a target heat source in the manner described above. That is, the central processing unit 102 can be configured to be thermally connected to the side of the housing 312 facing the heat-generating component 100, thereby accelerating the heat dissipation of the central processing unit 102 to a larger area. Furthermore, the target heat source may also include other components, such as those in… Figure 1 In the exemplary embodiment shown, the heat-generating component 100 includes a power supply module 103 that powers the central processing unit 102. The power supply module 103 also generates a high amount of heat when it is in operation. Therefore, the target heat source may include the power supply module 103.

[0043] There are several options for the thermally conductive connection between the target heat source component and the housing 312 of the air outlet assembly 310. For example, the target heat source component can be directly attached to the housing 312, or the target heat source component can be connected to the housing 312 through a thermally conductive layer. The thermally conductive layer can be in various forms such as thermal paste or thermal pads. Both sides of the thermally conductive layer are directly connected to the target heat source component and the housing 312 of the air outlet assembly 310, respectively, thereby transferring the heat from the target heat source component to the housing 312. See also Figure 6 In some embodiments, a heat-conducting plate 700 can be disposed between the housing 312 of the air outlet assembly 310 and the target heat source components. The heat-conducting plate 700 is connected to at least two target heat source components simultaneously, and the heat from the target heat source components is transferred to the housing 312 of the air outlet assembly 310 through the heat-conducting plate 700. The heat-conducting plate 700 can provide a large diffusion area for the heat from multiple target heat source components simultaneously, playing a role in temperature uniformity. At the same time, the heat-conducting plate 700 itself is easy to shape and process, and can well adapt to situations where there are height differences between target heat source components, thereby helping to reduce the requirements for the dimensional accuracy of the housing 312. The heat-conducting plate 700 can be made of various forms such as copper or aluminum alloy.

[0044] See Figure 3 Heat source components with relatively low heat generation on the heating component 100, such as the flexible cable 400 and the solid-state drive 104, can be set outside the orthogonal projection of the air outlet assembly 310 onto the display assembly 600. That is, heat source components with relatively low heat generation can be set outside the area of ​​the heating component 100 corresponding to the air outlet assembly 310 as much as possible, so that the area between the air outlet assembly 310 and the heating component 100 is reserved as much as possible for heat source components with relatively high heat generation.

[0045] In some embodiments, an air inlet 311 may be provided on the side of the housing 312 facing away from the heating element 100. Since the display component 600, the heating element 100, and the air outlet component 310 are stacked sequentially, the size of the housing 312 of the air outlet component 310 in the stacking direction should not be too large in order to minimize the overall size of the electronic device in the stacking direction. For example, the air outlet component 310 can be configured as a centrifugal fan. When the size of the housing 312 in the stacking direction is relatively small, the side of the housing 312 facing away from the heating element 100 has a large area. Therefore, the air inlet 311 is provided on the side of the housing 312 facing away from the heating element 100 so that the air inlet 311 has a large airflow cross-section. See also Figure 5 and Figure 6In some embodiments, a secondary air inlet 313 may be provided on the side of the housing 312 facing the heating element 100. In this way, the heat in the area between the heating element 100 and the housing 312, such as the heat dissipated into the surrounding air by the aforementioned target heat source, can enter the housing 312 of the air outlet assembly 310 through the secondary air inlet 313, thereby improving the heat dissipation efficiency.

[0046] In some embodiments, the fan's rotation axis can be eccentrically positioned within the housing 312, so that two opposite sidewalls of the housing 312 in the eccentric direction of the rotation axis form a first zone and a second zone with different operating air pressures between them and the fan. The aforementioned first air outlet is formed on the sidewall of the housing 312 corresponding to the zone with the higher operating air pressure. See also Figure 2 The fan's rotation axis is offset relative to the center of the housing 312 of the air outlet assembly 310. Figure 2 The fan is positioned to the left, so the distance between the fan and the left side wall of the housing 312 of the air outlet assembly 310 is smaller than the distance between the fan and the right side wall of the housing 312. This results in a greater working air pressure between the left side wall of the housing 312 and the fan compared to the right side wall. Therefore, the first air outlet is located on the right side wall of the housing 312. Figure 2 At position B, the air generated by the fan leaves the air outlet assembly 310 from a position with relatively low working air pressure and goes to the target body 320. This allows a small portion of the total air volume to be taken and sent to the target area between the heat-generating component 100 and the display component 600, so that most of the remaining air volume can be sent to other places that need more air volume, thus achieving a more reasonable and efficient use of the total air volume of the fan.

[0047] It should be noted that, in Figure 2 In the exemplary embodiment shown, the housing 312 and target body 320 of the air outlet assembly 310 are integrally formed. In other embodiments, the housing 312 and target body 320 may be two connected parts, which is not limited in this application. There are various options for the integral forming of the housing 312 and target body 320. For example, the housing 312 and target body 320 may be integrally injection molded from plastic, or the housing 312 and target body 320 may be made from the same metal part (copper, aluminum, etc.) through sheet metal processing; that is, the housing 312 and target body 320 are two parts of that metal part. In embodiments where the housing 312 and target body 320 are two connected parts, the target body 320 may be a plastic part or a metal part (e.g., copper, aluminum, etc.). The materials of the housing 312 and target body 320 may be the same or different. The connection method between the housing 312 and target body 320 may include welding, riveting, bonding, insertion, etc.

[0048] In some embodiments, the electronic device may include a battery module 500, which is located on the same side of the display component 600 as the heating element 100. The battery module 500 may have a bent portion formed by a bending extension, such that the orthographic projection of the battery module 500 onto the display component 600 includes a preset area. The preset area is obtained by a first case where the air outlet component 310 is located on the side of the heating element 100 facing away from the target area, compared to a second case where the orthographic projections of the air outlet component 310 and the heating element 100 onto the display component 600 do not overlap. In conventional arrangements of the air outlet component 310 and the heating element 100, they are typically arranged in the same layer, in which the orthographic projections of the air outlet component 310 and the heating element 100 onto the display component 600 do not overlap. In the electronic device provided in this application, the air outlet assembly 310 is located on the side of the heating element 100 facing away from the target area, so that the display component 600, the heating element 100, and the air outlet assembly 310 are stacked sequentially. Compared with the conventional arrangement described above, the heating element 100 and the air outlet assembly 310 occupy a smaller area on the back side of the display component 600. That is, compared with the conventional arrangement described above, this application can save some area on the back side of the display component 600 to arrange other components. This saved area can be called a preset area. Utilizing the preset area to arrange the battery module 500 is beneficial for configuring a large-capacity battery module 500 in the electronic device, thereby achieving long battery life. To this end, this application provides a bent portion formed by a bent extension in the battery module 500. Compared with the conventional straight battery module 500, this better adapts to the stacked arrangement of the air outlet assembly 310 and the heating element 100, so that the frontal projection of the battery module 500 onto the display component 600 can include the aforementioned preset area.

[0049] See Figures 2-4 In some embodiments, the battery module 500 can be configured as a U-shape, that is, the battery module 500 has two bends, and the heating element 100 is arranged in... Figure 2Within the area indicated by the dashed box A, the battery module 500 extends around the periphery of the heating element 100. Specifically, the battery module 500 extends along three sides of the heating element 100 on a surface parallel to the display surface of the display component 600. In this structure, the heating element 100 and the air outlet component 310 are located in the center of the electronic device, with most of the battery module 500 arranged on either side of them. This allows for a more balanced overall mass distribution in the electronic device, which is beneficial for improving the user experience, especially when the device is handheld. Alternatively, in other embodiments, the battery module 500 can be configured as an L-shape, meaning it has a bend. In this configuration, the battery module 500 can extend along two sides of the heating element 100 on a surface parallel to the display surface of the display component 600.

[0050] In some embodiments, the electronic device may have handholds at both ends in the target direction for gripping, allowing the user to hold the electronic device with both hands. The target direction is parallel to the display surface of the display component 600. It is easy to understand that when the user holds both ends of the electronic device to view the display surface of the display component 600, the target direction, which is parallel to the display surface of the display component 600, points to the left and right sides of the user's body. When the electronic device has a relatively regular shape, such as being roughly rectangular, the handholds can be provided by the edges of the electronic device's casing. For example, the ends of the electronic device's casing can be rounded to facilitate gripping. Alternatively, the handholds can be provided by making the electronic device's casing an irregular shape. For example, a raised structure can be provided on the back edge of the electronic device's casing, which allows for a more secure grip.

[0051] In some embodiments, the electronic device may include a first fin assembly 210 connected to a target region for transmitting airflow from the target region. See also Figures 3-6 The first fin assembly 210 includes a plurality of first heat dissipation fins 211. Airflow from the channel 321 of the target body 320 passes through the target area between the heat-generating component 100 and the display component 600, enters the first fin assembly 210, and flows through the gaps between the first heat dissipation fins 211. The first fin assembly 210 can guide the airflow from the target area to the heat dissipation vents on the electronic device housing, and can enhance the heat dissipation efficiency through the heat dissipation effect of the first heat dissipation fins 211.

[0052] In some embodiments, the electronic device may include a second fin assembly 220 connected to a second air outlet 314 of the air outlet assembly 310 for transmitting airflow from the second air outlet 314. See also Figures 3-6The second fin assembly 220 includes a plurality of second heat dissipation fins 221. Air from the second air outlet 314 enters the second fin assembly 220 and flows through the gaps between the second heat dissipation fins 221. The second fin assembly 220 can guide the airflow from the second air outlet 314 toward the heat dissipation vents on the electronic device housing, and can enhance the heat dissipation efficiency through the heat dissipation effect of the second heat dissipation fins 221.

[0053] In some embodiments, the second fin assembly 220 and the first fin assembly 210 can be disposed in the same direction as the air outlet assembly 310, so that the second fin assembly 220 and the first fin assembly 210 can direct airflow to the same heat dissipation vent on the electronic device housing. Of course, in other embodiments, the second fin assembly 220 and the first fin assembly 210 can be disposed in different directions as the air outlet assembly 310. For example, a first heat dissipation vent corresponding to the first fin assembly 210 and a second heat dissipation vent corresponding to the second fin assembly 220 can be respectively provided on different sides of the electronic device housing.

[0054] See Figure 6 In the case where the electronic device includes a first fin assembly 210 and / or a second fin assembly 220, the electronic device may include a heat-conducting element 800. The heat-conducting element 800 connects the first fin assembly 210 and / or the second fin assembly 220 to a heat source element on the heating element 100, for transferring heat from the heat source element to the first fin assembly 210 and / or the second fin assembly 220. The heat-conducting element 800 may take various forms, such as a heat pipe or a heat spreader, and this application does not limit it to any particular form.

[0055] In some embodiments, the first fin assembly 210 and the second fin assembly 220 can be configured as an integral structure, such as... Figure 6 As shown, the first fin assembly 210 and the second fin assembly 220 are two parts of the fin module 200. Based on this, an airflow baffle 230 can be provided at the junction of the first fin assembly 210 and the second fin assembly 220. As mentioned earlier, the first fin assembly 210 is used to transmit airflow from the target area, that is, airflow from the first air outlet of the air outlet assembly 310, while the second fin assembly 220 is used to transmit airflow from the second air outlet 314 of the air outlet assembly 310. By providing the airflow baffle 230, the airflow from one of the first fin assembly 210 and the second fin assembly 220 can be prevented from flowing back to the other. That is, the airflow baffle 230 can prevent the airflow transmitted by the first fin assembly 210 and the second fin assembly 220 from interfering with each other, thereby making the airflow smoother.

[0056] See Figures 3-6In some embodiments, a guide structure may be provided at the end of the channel 321 of the target body 320 connected to the target area. This guide structure directs the airflow from the channel 321 toward the end of the target area away from the first fin assembly 210. The guide structure defines the flow direction of the airflow as it leaves the channel 321, ensuring that after entering the target area (the area between the heating element 100 and the display element 600), the airflow first flows toward the end of the target area away from the first fin assembly 210. Figure 4 As shown, the end of the channel 321 of the target body 320 connected to the target area corresponds to position D in the orthographic projection of the display component 600. After the airflow enters the target area, it flows from position D in the direction indicated by arrow C. That is, the airflow first blows towards the end of the target area away from the first fin assembly 210, and then flows towards the position where the first fin assembly 210 is located. This arrangement allows the airflow to flow more comprehensively over the area between the heat-generating component 100 and the display component 600, thereby improving the overall heat dissipation effect.

[0057] Of course, the electronic device can achieve airflow first towards the end of the target area away from the first fin assembly 210 in other ways. For example, the target area can be provided with an air guide, which is used to guide the airflow from the channel 321 towards the end of the target area away from the first fin assembly 210. The air guide can be in various forms such as a baffle or a duct. In addition, the electronic device can also achieve airflow first towards the end of the target area away from the first fin assembly 210 by combining the above two methods. That is, an air guide structure is provided at the end of the channel 321 of the target body 320 that is connected to the target area, and an air guide is also provided in the target area, i.e., the area between the heating element 100 and the display component 600.
