20200241610
This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0010505, filed on Jan. 28, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
The disclosure relates generally to an electronic device, and more particularly, to an electronic device having a thermal diffusion structure.
Electronic devices, such as mobile terminals, smart phones, or wearable devices, can provide various functions including a basic voice communication function and other functions such as a short-range wireless communication (e.g., Bluetooth® (BT), wireless fidelity (Wi-Fi), near field communication (NFC), mobile communication (e.g., third generation (3G), fourth generation (4G), and fifth generation (5G) functions, music or video play, photographing, and a navigation functions.
Recent electronic devices can support high-speed data communication (e.g., millimeter wave communication). Such electronic devices can separately include an antenna module for high-speed data communication.
However, the conventional antenna module for high-speed data communication generates excess heat at operation.
In addition, the antenna module supporting high-speed communication can be mounted on a side surface of an electronic device, rendering it difficult to secure a space for applying a heat emission structure to the side surface of the electronic device, which tends to be minimal. For example, when the conventional heat emission structure is applied, a problem arises in having to change a design of the electronic device in order to secure an additional space for the heat emission structure.
Accordingly, there is a need in the art for a method for decreasing the heat generated by the antenna module, as well as an improved structure for antenna heat emission.
Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a thermal diffusion structure (or heat emission structure) that minimizes a mounting space.
Another aspect of the present disclosure is to provide a heat emission structure that effectively diffuses and emits heat.
In accordance with an aspect of the disclosure, an electronic device includes a housing including a first surface, a second surface facing the first surface, and a third surface vertical to the first surface and the second surface, a display exposed through at least part of the first surface, a battery arranged between the first surface and the second surface, a heating source arranged between the battery and the third surface in a direction vertical to the first surface and the second surface, and a first thermal diffusion member arranged vertically to the first surface and the second surface, the first thermal diffusion member including a first portion in thermal contact with at least part of the heating source and diffusing heat provided by the heating source to at least one second portion.
In accordance with another aspect of the disclosure, an electronic device includes a housing, a display exposed through at least part of a front surface of the housing, a battery arranged within the housing, an antenna module arranged vertically to the display between the battery and a side surface of the housing, and supporting communication at a frequency band of at least 20 gigahertz (GHz), a conductor plate thermally contacting at least part of an inner side surface of the antenna module at a first end of the conductor plate, and a heat pipe contacting the first end of the conductor plate at a first end of the heat pipe, and arranged vertically to the display.
In accordance with another aspect of the disclosure, an electronic device includes a housing, a display exposed through at least part of a front surface of the housing, a battery arranged within the housing, an antenna module arranged vertically to the display between the battery and a side surface of the housing, and supporting communication at a frequency band of at least 20 GHz, and a heat pipe thermally contacting at least part of an inner side surface of the antenna module at a first portion of the heat pipe and arranged vertically to the display.
The above and other aspects, features and advantages of certain embodiments of the disclosure will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Embodiments of the disclosure are described below with reference the accompanying drawings. In the disclosure, embodiments are described in the drawings and a related detailed description is set forth, but this is not intended to limit the embodiments of the disclosure. Descriptions of well-known functions and constructions are omitted for the sake of clarity and conciseness.

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 the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the AP) and supports a direct (e.g., wired) communication or a 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 with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. 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 subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the SIM card 196.

The display 301 may be exposed through at least part of a front surface of the electronic device, and may be supported by the bracket 31. At least part of the bracket 31 may be formed of metal. Part of the bracket 31 may be coupled or combined to the side housing 32, which may be formed of an injection product (e.g., plastic).
The battery 350 may be arranged within the electronic device (e.g., between the front surface and rear surface of the electronic device). The antenna module 310 may be positioned between the battery 350 and the side housing 32. The antenna module 310 may be arranged vertically to the front surface and rear surface of the electronic device.
The antenna module 310 may include at least one communication module 311 processing a high-speed wireless signal, a substrate 313 in which the at least one communication module 311 is mounted, and an antenna pattern 312. The communication module 311 may be arranged in an inner side surface 313a of the substrate 313, and the antenna pattern 312 may be arranged in an outer side surface 313b of the substrate 313. The communication module 311 may further include a member for shielding an electromagnetic wave provided by a communication circuit, and an external interference signal. For example, a conductive shield can or a conductively coated injection member may surround at least part of the communication module 311.
At least the communication module 311 of an inner side surface of the antenna module 310 may thermally contact the conductor plate 320. For example, the inner side surface of the antenna module 310 and the conductor plate 320 may contact each other by thermal interfacing materials (TIMs) 340 (i.e., first thermal interfacing materials). The TIMs 340 may be a single layer or a multi-layer and may have a thermal conductivity. For example, the TIMs 340 may have a thermal conductivity of approximately 1 W/mk or more (e.g., approximately 4 W/mk). Also, the TIMs 340 may or may not have electrical conductivity. For example, when the TIMs 340 have the electrical conductivity, the TIMs 340 may shield electrical noise or an electro-magnetic interference (EMI). The TIMs 340 may also have excellent abrasion resistance or heat resistance and may include thermoplastic materials.
The TIMs 340 may include phase change materials (PCMs) that may change from a solid phase to a liquid phase by heat. The phase change materials of the liquid phase may have viscosity and may be compressive or non-compressive. The TIMs 340 may include materials having at least one physical property that is changed by heat. For example, the thermal interfacing materials may have a high viscosity by virtue of the heat.
The TIMs 340 may be molded in a scheme of surface-processing thermal conductive materials (e.g., silicon, silicone polymer, graphite, acrylic, etc.).
The conductor plate 320 may collect and diffuse heat provided from the antenna module 310, and may be formed of high thermal conductivity materials, such as copper.
The conductor plate 320 may have a specific shape (e.g., a rectangular shape), and may contact an upper surface (e.g., the communication module 311) of the antenna module 310 through the TIMs 340. As illustrated in
The heat pipe 330 may be a thermal interfacing member capable of transferring a large amount of heat to a relatively low-temperature region by using a fluid of a high specific heat. For example, the heat pipe 330 may control transferring heat provided from the antenna module 310 to the relatively low-temperature region, diffusing a heat transfer path to a region around the heat pipe 330, and dispersing the heat to a region away from the region around the heat pipe 330. This heat pipe 330 has a known construction, and thus, a detailed description thereof is omitted.
The heat pipe 330 may be a heat transfer path, a heat transfer diffusion path, or a heat dispersion path. The heat pipe 330 may be constructed in various shapes, may have one end in contact with the conductor plate 320, and may have an opposing end arranged in a low-temperature region. The heat pipe 330 may be constructed in a shape of a flat section so as to maximize an adhesive surface of the conductor plate 320.
As illustrated in
The thermal diffusion member (e.g., the conductor plate 320 and the heat pipe 330) may contact the bracket 31 of metal materials. Through this, the heat provided by the antenna module 310 may be diffused via the bracket 31 of metal materials.
As the antenna module 310, the conductor plate 320, and the heat pipe 330 are arranged in a vertical direction not a horizontal direction with respect to the front surface and rear surface of the electronic device 200, the above-described embodiment may minimize a transverse (e.g., X axis) size of a mounting space for mounting a heat emission structure. In turn, the electronic device 200 may secure a mounting space (e.g., transverse length) of the battery 350, and/or may prevent an increase of a transverse size of the electronic device 200.

The heat pipe 420 may include a first portion 421 and at least one second portion 422. The first portion 421 thermally contacts the antenna module 410 through the thermal interfacing materials 440. The at least one second portion 422 has a height difference with the first portion 421 and is extended in parallel with the first portion 421. The first portion 421 may have a thinner thickness (e.g., a length of a horizontal direction) than the second portion 422, which minimizes a mounting space of a transverse direction (e.g., an X-axis direction of
The first potion 421 may not have a structure (e.g., wick structure) for thermal diffusion or may have a smaller structure than the second portion 422. The first portion 421 may have a specific strength enabling it to support the antenna module 410.
A part (e.g., the first portion 421) of the heat pipe 420 may have a role/function of the conductor plate 320 of
In the above-described heat emission structure, heat provided by the communication module 411 may be transferred to the first portion 421 of the heat pipe 420 through the heat interfacing materials 440, and the heat transferred to the first portion 421 may be moved and/or diffused to a low-temperature region through the second portion 422 of the heat pipe 420.

The conductor plate 520 may have a ‘┐’ shape and may include a contact surface 522 and a support surface 521. The contact surface 522 contacts the communication module 511 of the antenna module 510 through the thermal interfacing materials 540. The support surface 521 is extended vertically to the contact surface 522 and supports the contact surface 522. For example, the support surface 521 may be coupled to the bracket 51, thereby more stably supporting the antenna module 510.
The support surface 521 may be positioned at a lower end of the display 501, and may contact another thermal diffusion member (e.g., a vapor chamber) diffusing heat of the display 501.
In the above-described heat emission structure, heat provided by the communication module 511 may be transferred to the contact surface 522 of the conductor plate 520 via the thermal interfacing materials 540, and may be moved/diffused to a low-temperature region via the heat pipe 530 connected to the contact surface 522. The heat transferred to the contact surface 522 may be moved/diffused to the low-temperature region, by means of the bracket 51 connected with the support surface 521, and/or another thermal diffusion member.

An electronic device (e.g., the electronic device (101), the electronic device (200)) as described above includes a housing; a display (e.g., the display device (160), the display (201), the display (301), the display (401), the display (501)) exposed through at least part of a front surface of the housing, a battery (e.g., the battery (189), the battery (350), the battery (450), the battery (550)) arranged within the housing, an antenna module (e.g., the antenna module (310), the antenna module (410), the antenna module (510)) arranged vertically to the display between the battery and a side surface of the housing, and supporting communication at a frequency band of 20 GHz or more, and a heat pipe (e.g., the heat pipe (420)) thermally contacting at one portion with at least part of an inner side surface of the antenna module, and arranged vertically to the display.
The heat pipe may include a first portion (e.g., the first portion (421)) thermally contacting with the antenna module through the thermal interfacing materials, and at least one second portion (e.g., the second portion (422)) having a height difference with the first portion, and extended in parallel with the first portion.
A horizontal length of the first portion may be less than a horizontal length of the second portion.
By minimizing a mounting space of a heat emission component, the electronic device of the present disclosure cures a limit in structure change, battery size decrease, and terminal size increase of the electronic device. Also, the present disclosure may effectively diffuse heat provided by the antenna module and thus, may provide stable high-speed data communication. For example, embodiments of the disclosure may decrease a frequency in which, due to a high temperature, high-speed data communication is limited by a communication module or an AP.
The electronic device according to various embodiments may be one of various types of electronic devices. The electronic devices may include, for example, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.
It should be appreciated that various embodiments of the present disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms such as “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute the instructions, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one invoked instruction. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
A method according to embodiments of the disclosure may be included and provided in a computer program product that may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
Each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities. One or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally,. a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. Operations performed by the module, the program, or another component may be performed sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
