Abstract
Description
Electronic devices including heat dissipation structures
[0001] Various embodiments disclosed in this document relate to electronic devices, for example, electronic devices including a heat dissipation structure.
[0002] Electronic devices can refer to devices that perform specific functions based on the programs installed on them, such as home appliances, electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, audio / video devices, desktop / laptop computers, or car navigation systems. For example, these electronic devices can output stored information as audio or video. As electronic device integration increases and ultra-high-speed, high-capacity wireless communications become more widespread, a single electronic device, such as a mobile communication terminal, can be equipped with various functions. For example, in addition to communication functions, entertainment functions such as games, multimedia functions such as music / video playback, communication and security functions for mobile banking, or functions such as schedule management or electronic wallets are being integrated into a single electronic device.
[0003] As the use of personal or portable communication devices, such as smartphones, becomes more widespread, user demand for portability and ease of use is increasing. For example, a touchscreen display can serve as an output device, such as a screen that outputs visual information, while also providing a virtual keypad that replaces mechanical input devices (e.g., button-type input devices). This allows portable communication devices or electronic devices to be miniaturized while still offering the same or improved usability (e.g., a larger screen). On the other hand, the commercialization of flexible displays, such as those that can be folded or rolled, is expected to further enhance the portability and usability of electronic devices. Electronic devices including flexible displays can be carried in a folded or rolled state with multiple different structures (e.g., housings) and can provide a large screen when unfolded, thereby enhancing portability and usability.

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.
[0035] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).
[0050] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.
[0053] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).
[0054] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

For example, in one embodiment, the first housing (210) and the first rear cover (280) may be formed integrally, and the second housing (220) and the second rear cover (290) may be formed integrally.
[0067] According to one embodiment, the first housing (210) is connected to a hinge structure (e.g., the hinge structure (202) of FIG. 4) and may include a first front surface (210a) facing a first direction and a first rear surface (210b) facing a second direction opposite to the first direction. The second housing (220) is connected to the hinge structure and includes a second front surface (220a) facing a third direction and a second rear surface (220b) facing a fourth direction opposite to the third direction, and may rotate with respect to the first housing (210) about the hinge structure (202). Accordingly, the electronic device (101) may be variable between a folded state and an unfolded state. The folding or unfolding motion of the electronic device (101) can be understood as the rotation of the first housing (210) with respect to the hinge structure or the rotation of the second housing (220) with respect to the hinge structure. When the electronic device (101) is in a folded state, the first front side (210a) can face the second front side (220a). When the electronic device (101) is in an unfolded state, the third direction can be the same as the first direction. In the following, unless otherwise stated, the directions are described based on the unfolded state of the electronic device (101).
[0068] According to one embodiment, the first housing (210) and the second housing (220) are arranged on both sides with respect to the folding axis (Ax) as the center, and may have an overall symmetrical shape with respect to the folding axis (Ax). As described below, the angle or distance between the first housing (210) and the second housing (220) may vary depending on whether the state of the electronic device (101) is in an unfolded state, a folded state, or an intermediate state. According to one embodiment, the second housing (220) additionally includes a sensor area (224) in which sensors (e.g., a front camera) are arranged, but may have a shape that is symmetrical with respect to the first housing (210) in other areas.
[0069] According to one embodiment, the folding axis (Ax) may be a plurality of parallel folding axes (e.g., two). In the present disclosure, the folding axis (Ax) is provided along the longitudinal direction (Y-axis direction) of the electronic device (101), but the direction of the folding axis (Ax) is not limited thereto. For example (not shown), an embodiment may be implemented in which the electronic device (101) includes a folding axis extending along the width direction (e.g., X-axis direction).
[0070] According to one embodiment, the electronic device (101) may include a structure into which a digital pen (not shown) can be attached. For example, the electronic device (101) may include a magnetic body configured to attach the digital pen to a side of the first housing (210) or a side of the second housing (220).

[0071] According to one embodiment, at least a portion of the first housing (210) and the second housing (220) may be formed of a metallic or non-metallic material having a rigidity of a size selected to support the display (230). At least a portion formed of the metallic material may provide a ground plane of the electronic device (101) and may be electrically connected to a ground line formed on a printed circuit board (e.g., the board portion (260) of FIG. 4).
[0072] According to one embodiment, the sensor area (224) may be formed to have a predetermined area adjacent to one edge or one corner of the second housing (220). However, the arrangement, shape, and size of the sensor area (224) are not limited to the illustrated example. For example, in another embodiment, the sensor area (224) may be provided in another corner of the second housing (220) or any area between the upper and lower corners or in the first housing (210). In one embodiment, components for performing various functions built into the electronic device (101) may be exposed to the front of the electronic device (101) through the sensor area (224) or through one or more openings provided in the sensor area (224). In one embodiment, the components may include various types of sensors. The sensor(s) may include, for example, at least one of a front camera, a receiver, or a proximity sensor.
[0073] According to one embodiment, the first rear cover (280) is disposed on one side of the folding axis (Ax) at the rear of the electronic device (101) and may have, for example, a substantially rectangular periphery, the periphery of which may be wrapped by another structure of the first housing (210). Similarly, the second rear cover (290) is disposed on the other side of the folding axis (Ax) at the rear of the electronic device (101) and the periphery of which may be wrapped by another structure of the second housing (220).
[0074] According to one embodiment, the first rear cover (280) and / or the second rear cover (290) may have a shape that is substantially symmetrical about the folding axis (Ax). However, the first rear cover (280) and the second rear cover (290) do not necessarily have mutually symmetrical shapes, and in one embodiment, the electronic device (101) may include the first rear cover (280) and the second rear cover (290) of different shapes that are not symmetrical.
[0075] In one embodiment, the first rear cover (280), the second rear cover (290), the first housing (210), and the second housing (220) may provide spaces in which various components of the electronic device (101) (e.g., a printed circuit board or a battery) may be placed. In one embodiment, one or more components may be placed or visually exposed on the rear surface of the electronic device (101). For example, at least a portion of the sub-display (234) may be visually exposed through at least a portion of the first rear cover (280). In another embodiment, one or more components or sensors may be visually exposed through at least a portion of the second rear cover (290). In various embodiments, the sensors may include a proximity sensor and / or a camera module (206) (e.g., a rear camera).
[0076] According to one embodiment, a front camera exposed to the front of the electronic device (101) through one or more openings provided in the sensor area (224) or a camera module (206) exposed through at least a portion of the second rear cover (290) may include one or more lenses, image sensors, and / or image signal processors. In some embodiments, two or more lenses (infrared camera, wide-angle and telephoto lenses) and image sensors may be arranged on one side of the electronic device (101).
[0077] According to one embodiment, the hinge cover (240) may be disposed between the first housing (210) and the second housing (220) to cover internal components (e.g., the hinge structure (202) of FIG. 4). According to one embodiment, the hinge cover (240) may be covered by a portion of the first housing (210) and the second housing (220) or exposed to the outside, depending on the state of the electronic device (101) (flat state or folded state).
[0078] According to one embodiment, as illustrated in FIG. 2, when the electronic device (101) is in an unfolded state, the hinge cover (240) may be covered by the first housing (210) and the second housing (220) and may not be exposed. As another example, as illustrated in FIG. 3, when the electronic device (101) is in a folded state (e.g., a fully folded state), the hinge cover (240) may be exposed to the outside between the first housing (210) and the second housing (220). As another example, when the first housing (210) and the second housing (220) are in an intermediate state where they are folded at a certain angle, the hinge cover (240) may be partially exposed to the outside between the first housing (210) and the second housing (220). However, in this case, the exposed area may be less than that in the fully folded state. In one embodiment, the hinge cover (240) may include a curved surface.
[0079] According to one embodiment, the display (230) may be positioned on a space formed (or defined) by the housing (201). For example, the display (230) may be seated on a recess provided by the housing (201) and may form a majority of the front surface of the electronic device (101). Accordingly, the front surface of the electronic device (101) may include the display (230), a portion of the first housing (210) adjacent to the display (230) and a portion of the second housing (220). The back surface of the electronic device (101) may include a first back cover (280), a portion of the first housing (210) adjacent to the first back cover (280), a second back cover (290), and a portion of the second housing (220) adjacent to the second back cover (290).
[0080] In one embodiment, the display (230) may include a plurality of display areas spaced apart from each other. For example, the display (230) may include a first display area (231) disposed on a first housing (210), a second display area (232) disposed on a second housing (220), and a folding area (233). In one embodiment, the first display area (231) and the second display area (232) may rotate about a folding axis (Ax).
[0081] According to one embodiment, the display (230) may refer to a display in which at least a portion of the display can be transformed into a flat or curved surface. For example, the display (230) may be a foldable or flexible display. According to one embodiment, the display (230) may include a folding area (233), a first display area (231) arranged on one side (e.g., the left side of the folding area (233) illustrated in FIG. 2) with respect to the folding area (233), and a second display area (232) arranged on the other side (e.g., the right side of the folding area (233) illustrated in FIG. 2). However, the division of the areas of the display (230) is exemplary, and the display (230) may be divided into a plurality of areas (e.g., four or more or two) depending on the structure or function. For example, in the embodiment illustrated in FIG. 2, the display (230) may be divided into regions by a folding region (233) or a folding axis (Ax) extending parallel to the Y-axis, but in other embodiments, the display (230) may be divided into regions based on other folding regions (e.g., a folding region parallel to the X-axis) or other folding axes (e.g., a folding axis parallel to the X-axis). According to one embodiment, the display (230) may be coupled to or disposed adjacent to a touch detection circuit, a pressure sensor capable of measuring the intensity (pressure) of a touch, and / or a digitizer (not shown) configured to detect a magnetic field-type stylus pen.
[0082] According to one embodiment, the first display area (231) and the second display area (232) may have an overall symmetrical shape centered on the folding area (233). According to one embodiment (not shown), the second display area (232), unlike the first display area (231), may include a cut notch depending on the presence of the sensor area (224), but may have a shape that is substantially symmetrical with respect to the first display area (231) in other areas. For example, the first display area (231) and the second display area (232) may include a portion having a symmetrical shape with respect to each other and a portion having an asymmetrical shape with respect to each other.
[0083] Hereinafter, the operation of the first housing (210) and the second housing (220) and each area of the display (230) according to the state of the electronic device (101) (e.g., flat state or unfolded state and folded state) will be described.

The surface of the first display area (231) of the display (230) and the surface of the second display area (232) may form a 180-degree angle with each other and face the same direction (e.g., toward the front of the electronic device). The folding area (233) may form the same plane as the first display area (231) and the second display area (232).
[0085] According to one embodiment, when the electronic device (101) is in a folded state (e.g., FIG. 3), the first housing (210) and the second housing (220) may be arranged to face each other. The surface of the first display area (231) of the display (230) and the surface of the second display area (232) may form a narrow angle (e.g., between about 0 and 10 degrees) with each other and may face each other. When the electronic device (101) is in a folded state, at least a portion of the folding area (233) may be formed as a curved surface having a predetermined curvature.
[0086] According to one embodiment, when the electronic device (101) is in an intermediate state (not shown), the first housing (210) and the second housing (220) may be arranged at a certain angle with respect to each other. The surface of the first display area (231) of the display (230) and the surface of the second display area (232) may form an angle that is greater than the angle in the folded state and less than the angle in the unfolded state. The folding area (233) may be formed as a curved surface having at least a certain curvature, and the curvature at this time may be less than that in the folded state.
