At least one of the components (e.g., the display device 160 or the camera module 180) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. Some of the components may be implemented as a single integrated circuit. For example, the sensor module 176 (eg, a fingerprint sensor, an iris sensor, or an illumination sensor) may be implemented to be embedded in the display device 160 (eg, a display).
[0030] The processor 120 may run, for example, software (e.g., program 140) to control at least one other component of the electronic device 101 connected to the processor 120 (e.g., a hardware component or a software component), and may perform various data processing or calculations. As at least part of the data processing or calculations, the processor 120 may load commands or data received from another component (e.g., sensor module 176 or communication module 190) into the volatile memory 132, process the commands or data stored in the volatile memory 132, and store the resulting data in the non-volatile memory 134. The processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)) and an auxiliary processor 123 (e.g., a graphics processing unit (GPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operationally independent of or integrated with the main processor 121. Additionally or alternatively, the auxiliary processor 123 may be configured to consume less power than the main processor 121 or to be specifically configured for a designated function. The auxiliary processor 123 may be implemented separately from the main processor 121 or as part of the main processor 121 .
[0031] When the main processor 121 is in an inactive (e.g., sleep) state, the auxiliary processor 123 may control at least some of the functions or states related to at least one component (e.g., the display device 160, the sensor module 176, or the communication module 190) among the components of the electronic device 101 (not the main processor 121), or when the main processor 121 is in an active state (e.g., running an application), the auxiliary processor 123 may control at least some of the functions or states related to at least one component (e.g., the display device 160, the sensor module 176, or the communication module 190) together with the main processor 121. The auxiliary processor 123 (e.g., ISP or CP) may be implemented as part of another component (e.g., camera module 180 or communication module 190) that is functionally related to the auxiliary processor 123.
[0032] The memory 130 may store data used by at least one component of the electronic device 101 (e.g., the processor 120 or the sensor module 176), which may include software (e.g., the program 140) and input data or output data for commands related to the program 140.

[0034] The input device 150 may receive commands or data from outside the electronic device 101 (e.g., a user) to be used by other components of the electronic device 101 (e.g., the processor 120). The input device 150 may include a microphone, a mouse, a keyboard, or a digital pen (e.g., a stylus).
[0035] The sound output device 155 can output sound signals to the outside of the electronic device 101. The sound output device 155 may include a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or records, and the receiver can be used for incoming calls. The receiver can be implemented separately from the speaker or as part of the speaker.
[0036] The display device 160 may visually provide information to the outside of the electronic device 101 (e.g., a user). The display device 160 may include a display, a holographic device, or a projector, and a control circuit for controlling a corresponding one of the display, the holographic device, and the projector. The display device 160 may include a touch circuit adapted to detect a touch or a sensor circuit adapted to measure the strength of the force caused by the touch (e.g., a pressure sensor).
[0037] The audio module 170 can convert sound into an electrical signal, or vice versa. The audio module 170 can obtain sound via the input device 150, or output sound via the sound output device 155 or an earphone of an external electronic device (e.g., electronic device 102) directly (e.g., wired) or wirelessly connected to the electronic device 101.
[0038] The sensor module 176 can detect the operating state of the electronic device 101 (e.g., power or temperature) or the environmental state outside the electronic device 101 (e.g., the state of the user), and then generate an electrical signal or data value corresponding to the detected state. The sensor module 176 may include a gesture sensor, a gyroscope sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illumination sensor.
[0039] The interface 177 may support one or more specific protocols for connecting the electronic device 101 directly (e.g., wired) or wirelessly to an external electronic device (e.g., the electronic device 102). The interface 177 may include a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.
[0040] The connection end 178 may include a connector through which the electronic device 101 can be physically connected to an external electronic device (eg, the electronic device 102). The connection end 178 may include an HDMI connector, a USB connector, an SD card connector, or an audio connector (eg, a headphone connector).
[0041] The haptic module 179 may convert the electrical signal into mechanical stimulation (eg, vibration or motion) or electrical stimulation that can be recognized by the user via his sense of touch or kinesthetic sense. The haptic module 179 may include a motor, a piezoelectric element, or an electrical stimulator.
[0042] The camera module 180 can capture still images or moving images. The camera module 180 may include one or more lenses, image sensors, ISPs, or flashes.
[0043] The power management module 188 may manage power supply to the electronic device 101. The power management module 188 may be implemented as at least part of a power management integrated circuit (PMIC).
[0044] The battery 189 may power at least one component of the electronic device 101. The battery 189 may include a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.
[0045] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., AP), and support direct (e.g., wired) communication or wireless communication. 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 (PLC) module). A corresponding one of these communication modules may communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth TM , Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (for example, a long-distance communication network such as a cellular network, the Internet, or a computer network (for example, a LAN or a wide area network (WAN)))). These various types of communication modules may be implemented as a single component (for example, a single chip), or may be implemented as multiple components separated from each other (for example, multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (for example, an International Mobile Subscriber Identity (IMSI)) stored in the SIM card 196.
[0046] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., an external electronic device). Antenna module 197 may include an antenna having a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). Antenna module 197 may include multiple antennas. In this case, communication module 190 (e.g., wireless communication module 192) may select at least one antenna from the multiple antennas that is suitable for the communication scheme used in the communication network (e.g., first network 198 or second network 199). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. Components other than the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may also be formed as part of antenna module 197.
[0047] At least some of the above components can be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general-purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.
[0048] Commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to second network 199. Each of electronic device 102 and electronic device 104 can be of the same type as electronic device 101, or a different type. All or some operations that would otherwise be executed on electronic device 101 can be executed on one or more of external electronic device 102, external electronic device 104, or server 108. For example, if electronic device 101 automatically performs a function or service or performs a function or service in response to a request from a user or another device, electronic device 101 can request one or more external electronic devices to perform at least part of the function or service instead of, or in addition to, performing the function or service. Upon receiving the request, the one or more external electronic devices can perform the requested at least part of the function or service, or perform another function or service related to the request, and transmit the result to electronic device 101. The electronic device 101 may provide the result as at least a partial reply to the request with or without further processing the result. To this end, for example, cloud computing technology, distributed computing technology, or client-server computing technology may be used.
[0049] Figure 2A A front surface of an electronic device according to an embodiment is shown. Figure 2B A rear surface of an electronic device according to an embodiment is shown.
[0050] Reference Figure 2A and Figure 2B In an embodiment, an electronic device 200 (e.g., electronic device 101) may be provided with a display 201 (e.g., display device 160) on a front surface (i.e., first surface) 2001 of a housing 250. A receiver 202 for outputting a voice of a counterpart may be provided above the display 201. A microphone 203 for acquiring (or collecting) the voice of a user of the electronic device 2000 for the counterpart may be provided below the display 201.
[0051] The electronic device 200 may be provided with components for performing various functions of the electronic device 200 around the location where the receiver 202 is installed. These components may include at least one sensor module 204. This sensor module 204 may include at least one of an illumination sensor (e.g., an optical sensor), a proximity sensor, an infrared sensor, and / or an ultrasonic sensor. These components may include a front camera 205 and an indicator 206 (e.g., a light emitting diode) for indicating status information of the electronic device 200 to the user.
[0052] The display 201 may be formed as a large screen, wherein the display 201 occupies most of the front surface 2001 of the electronic device 200. A home key 210a, a menu key 210b, and a back key 210c may be formed below the display 201.
[0053] The electronic device 200 may be provided with various electronic components on the lower surface 224. For example, the microphone 203, the speaker hole 208, the interface 207, and the headphone jack 209 may be provided on the lower surface 224. However, the embodiment is not limited thereto, and at least one of the above-mentioned electronic components may also be provided on the left side surface 221, the right side surface 222, or the upper side surface 223 of the housing 250.
[0054] The electronic device 200 may be provided with at least one first side key 211 on the left side surface 221. The at least one first side key 211 may be formed as a pair and may be provided on the left side surface 221 where a portion of the first side key 211 protrudes, and may perform, for example, volume up / down functions, scroll functions.
[0055] The electronic device 200 may be provided with at least one second side key 212 at the right side surface 222. The second side key 212 may, for example, perform a power on / off function, a wake-up and / or sleep function of the electronic device 200.
[0056] The electronic device 200 may be provided with a rear camera 213 on a rear surface (i.e., a second surface) 2002 facing the front surface, and at least one electronic component 214 may be arranged around the rear camera 213. For example, the electronic component 214 may include at least one of an illumination sensor (e.g., an optical sensor), a proximity sensor, an infrared sensor, an ultrasonic sensor, a heart rate sensor, a flash device, or a fingerprint scanning sensor.
[0057] The electronic device 200 may be provided with a heat source on at least one of the left side surface 221 and the right side surface 222. The heat source may be an antenna module for high-speed communication (e.g., millimeter wave communication) in a frequency band of approximately 20 GHz or higher. The antenna module may be arranged perpendicularly (e.g., in the Z-axis direction) to the front surface 2001 and the rear surface 2002 of the electronic device 200 between a battery (e.g., battery 189 (not shown)) and a side surface (i.e., the right side surface or the left side surface) of the electronic device 200.
[0058] The electronic device 200 may include a heat diffusion member for diffusing heat provided by a heat source to the outside of the electronic device. Figures 3A to 5B The heat dissipation structure including the heat diffusion member is described. For the convenience of description, it is assumed that the heat source is the antenna module.
[0059] Figure 3A A heat dissipation structure of an electronic device according to an embodiment is shown. Figure 3B It is along Figure 3A The cross section is taken along the line AA'. Figure 3C A heat diffusion member according to an embodiment is shown. Figure 3D FIG. 4 illustrates a heat dissipation path provided by an antenna module according to an embodiment.
[0060] Reference Figures 3A to 3D An electronic device of an embodiment of the present disclosure (eg, electronic device 101 or electronic device 200 ) may include a display 301 , a bracket 31 , a side housing 32 , an antenna module 310 , a conductor plate 320 , a heat pipe 330 , a thermal interface material 340 , and a battery 350 .
[0061] The display 301 may be exposed through at least a portion of the front surface of the electronic device and may be supported by a bracket 31. At least a portion of the bracket 31 may be formed of metal. A portion of the bracket 31 may be coupled or bonded to a side housing 32, which may be formed of an injection molded product (e.g., plastic).
[0062] The battery 350 may be disposed within the electronic device (eg, between the front and rear surfaces of the electronic device). The antenna module 310 may be located between the battery 350 and the side housing 32. The antenna module 310 may be disposed perpendicular to the front and rear surfaces of the electronic device.
[0063] The antenna module 310 may include at least one communication module 311 for processing high-speed wireless signals, a substrate 313 on which the at least one communication module 311 is mounted, and an antenna pattern 312. The communication module 311 may be arranged on an inner surface 313a of the substrate 313, and the antenna pattern 312 may be arranged on an outer surface 313b of the substrate 313. The communication module 311 may also include a member for shielding electromagnetic waves provided by the communication circuit and external interference signals. For example, a conductive shield or a conductively coated injection molded member may surround at least a portion of the communication module 311.
[0064] At least the communication module 311 on the inner surface of the antenna module 310 can be in thermal contact with the conductor plate 320. For example, the inner surface of the antenna module 310 and the conductor plate 320 can be in contact with each other via a thermal interface material (TIM) 340 (i.e., a first thermal interface material). The TIM 340 can be a single layer or multiple layers and can have thermal conductivity. For example, the TIM 340 can have a thermal conductivity of approximately 1 W / mK or higher (e.g., approximately 4 W / mK). Furthermore, the TIM 340 can be electrically conductive or non-conductive. For example, when the TIM 340 is electrically conductive, it can shield against electrical noise or electromagnetic interference (EMI). The TIM 340 can also have excellent wear resistance or heat resistance and can be made of a thermoplastic material.
[0065] TIM 340 may include a phase change material (PCM) that can change from a solid phase to a liquid phase by heat. A liquid phase PCM may have viscosity and may be compressible or incompressible. TIM 340 may include a material having at least one physical property that changes with heat. For example, a thermal interface material may have high viscosity due to heat.
[0066] The TIM 340 may be molded in a surface treated thermally conductive material such as silicon, silicone polymer, graphite, acrylic, etc.
[0067] The conductor plate 320 may collect and diffuse heat provided from the antenna module 310 and may be formed of a high thermal conductivity material such as copper.
[0068] The conductor plate 320 may have a specific shape (eg, a rectangular shape) and may contact the upper surface of the antenna module 310 (eg, the communication module 311) through the TIM 340. Figure 3C As shown, the conductor plate 320 may be adhered to the TIM 340 near the center of the conductor plate 320 and connected to the heat pipe 330 on both sides of the conductor plate 320. This is merely an example, and the conductor plate 320 may be connected to the heat pipe 330 on only one side of the conductor plate 320. The conductor plate 320 may contact the heat pipe 330 via a second thermal interface material or welding.
[0069] The heat pipe 330 may be a thermal interface member capable of transferring a large amount of heat to a relatively low-temperature area using a fluid having a high specific heat capacity. For example, the heat pipe 330 may control the transfer of heat provided by the antenna module 310 to a relatively low-temperature area, diffuse the heat transfer path to the area surrounding the heat pipe 330, and disperse the heat to areas away from the area surrounding the heat pipe 330. The heat pipe 330 has a known structure, and therefore a detailed description thereof is omitted.
[0070] Heat pipe 330 can be a heat transfer path, a heat transfer diffusion path, or a heat dissipation path. Heat pipe 330 can be configured in various shapes, can have one end in contact with conductor plate 320, and can have an opposite end arranged in a low temperature area. Heat pipe 330 can be configured in a flat cross-sectional shape to maximize the bonding surface of conductor plate 320.
[0071] like Figure 3D As shown, heat provided by the communication module 311 mounted in the substrate 313 can be transferred to the conductor plate 320 via the thermal interface material 340 , and moved and / or diffused to a lower temperature area via the heat pipe 330 connected to the conductor plate 320 .
[0072] The heat diffusion member (eg, the conductor plate 320 and the heat pipe 330 ) may contact the bracket 31 of the metal material. In this way, the heat provided by the antenna module 310 may be diffused through the bracket 31 of the metal material.
[0073] Since the antenna module 310, the conductor plate 320, and the heat pipe 330 are arranged vertically, rather than horizontally, relative to the front and rear surfaces of the electronic device 200, the above embodiment can minimize the lateral (e.g., X-axis) size of the installation space for installing the heat dissipation structure. In turn, the electronic device 200 can ensure the installation space (e.g., lateral length) of the battery 350 and / or can prevent the lateral size of the electronic device 200 from increasing.
[0074] Figure 4A A heat dissipation structure of an electronic device according to an embodiment is shown. Figure 4B It is along Figure 4A The cross section is taken along the line BB'. Figure 4C A heat diffusion member according to an embodiment is shown.
[0075] Reference Figures 4A to 4C , the electronic device may include a display 401 , a bracket 41 , a side housing 42 , an antenna module 410 , a heat pipe 420 , a thermal interface material 440 , and a battery 450 . Figures 4A to 4C The display 401, the bracket 41, the side housing 42, the antenna module 410 including the communication module 411, the antenna pattern 412 and the substrate 413, the thermal interface material 440 and the battery 450 are similar to Figures 3A to 3DThe display 301, the bracket 31, the side housing 32, the antenna module 310, the thermal interface material 340 and the battery 350 are shown in FIG. Therefore, a detailed description thereof is omitted.
[0076] The heat pipe 420 may include a first portion 421 and at least one second portion 422. The first portion 421 is in thermal contact with the antenna module 410 via the thermal interface material 440. The at least one second portion 422 has a height difference from the first portion 421 and extends parallel to the first portion 421.
