Abstract
Description
Technical Field
[0001] The present disclosure generally relates to heat transfer components and electronic devices including the same. Background Art
[0002] Advances in mobile technology are leading to increased demand for more compact and lightweight portable terminals (eg, smartphones) that maximize user portability and convenience and integrate components in a smaller space for higher performance.
[0003] As electronic components used in electronic devices provide higher performance and capabilities, they typically generate more heat, affecting nearby components and degrading overall performance.
[0004] For example, an electronic device may have a main circuit board that is elongated in the length direction of the electronic device, such as in the shape of the letter "I". At least a portion of a battery positioned adjacent to the main circuit board may be flush with the main circuit board. When at least a portion of the battery is flush with the I-shaped main circuit board, the increase in the size of the main circuit board may impose limitations on the available space for placing the battery. As viewed from above the electronic device, the I-shaped main circuit board may be sized to correspond to the mounting area of the electronic components. Therefore, placing a larger capacity battery compromises the miniaturization of the mounting area of the electronic components of the electronic device.
[0005] In order to place a larger battery in an electronic device, a half printed circuit board (PCB) may be used, ie, a PCB that occupies approximately half of the overall size of the display.
[0006] In order to avoid a significant reduction in the installation space of electronic components, a stacked PCB structure can be used to ensure additional installation area for electronic components. If an electronic device utilizes a semi-PCB and a stacked PCB, the main heat-generating components of the electronic device (such as an application processor (AP) or a fifth-generation (5G) modem) may be arranged close to each other on the main circuit board. Therefore, the heat generated when the electronic device is running may be concentrated in one part of the electronic device (such as the top), which may cause performance degradation of the electronic device. Therefore, heat dissipation and cooling of the heat source may be required.
[0007] In addition, 5G antennas and radio frequency integrated circuits (RFICs) for 5G communications may be mounted in modules separate from heat sources mounted on the main circuit board. Therefore, they may require separate coolers. Summary of the invention

[0010] According to one aspect of the present disclosure, a heat dissipation structure is provided that can effectively transfer heat generated from a portion (eg, a top portion) of an electronic device to another portion (eg, a bottom portion) of the electronic device where the temperature is relatively low.
[0011] According to another aspect of the present disclosure, a heat dissipation structure is provided, which can cool a modular heat source in an electronic device by transferring, diffusing, scattering or releasing heat generated from the heat source.

[0015] Advantageous Effects of the Invention
[0016] As is apparent from the foregoing description, according to various embodiments, use of a heat dissipation member and an electronic device including the same can effectively transfer heat generated from various electronic components of the electronic device to a relatively low temperature portion.

The heat sink includes a low dielectric constant material to prevent the efficiency of the wireless communication signal from being reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] The housing may include a first region (eg Figure 2C The first area is divided into a space from one end of the support member 230 along the length direction. The PCB 250 is disposed in the first area. The housing may include a second area (eg Figure 2CThe second area is located adjacent to the first area and divides the space in parallel with the first area. A battery for power supply is arranged in the second area. The housing may include a second area (e.g. Figure 2C The third region (e.g. Figure 2C An auxiliary PCB (eg, a PCB on which an interface is formed) is formed in the third region.

[0095] The electronic device 200 may include an antenna module 290.

As another example, a portion of the antenna module 290 may be configured to simultaneously send or receive radio waves with the same characteristics (referred to as radio waves of frequencies A1 and A2 in frequency band A) to achieve diversity. Another portion of the antenna module 290 may be configured to simultaneously send or receive radio waves with the same characteristics (referred to as radio waves of frequencies B1 and B2 in frequency band B) to achieve diversity.

[0098] Figure 3 An electronic device in a network environment including multiple cellular networks according to an embodiment is shown.
[0099] Reference Figure 3 , the electronic device 301 includes a first CP 312, a second CP 314, a first RFIC 322, a second RFIC 324, a third RFIC 326, a fourth RFIC 328, a first RF front end (RFFE) 332, a second RFFE 334, a first antenna module 342, a second antenna module 344, and an antenna 348. The electronic device 301 also includes a processor 120 and a memory 130. The second network 199 may include a first cellular network 392 and a second cellular network 394. The electronic device 301 may also include Figures 2A-2CThe second network 199 may further include at least one of the components of the wireless communication module 192. The first CP 312, the second CP 314, the first RFIC 322, the second RFIC 334, the fourth RFIC 328, the first RFFE 332, and the second RFFE 334 may form at least part of the wireless communication module 192. The fourth RFIC 328 may be omitted or included as part of the third RFIC 326.
[0100] The first CP 312 can establish a communication channel for a frequency band for wireless communication with the first cellular network 392, or can support traditional network communication via the established communication channel. The first cellular network can be a traditional network including a second generation (2G), a third generation (3G), a fourth generation (4G) and / or a long-term evolution (LTE) network. The second CP 314 can be a communication channel corresponding to a specified frequency band (e.g., from about 6 GHz to about 60 GHz) among the frequency bands for wireless communication with the second cellular network 394, or can support 5G network communication through the established communication channel. The second cellular network 394 can be a 5G network defined by the third generation partnership project (3GPP). In addition, the first CP 312 or the second CP 314 can be a communication channel corresponding to another specified frequency band (e.g., about 6 GHZ or lower) among the frequency bands for wireless communication with the second cellular network 394, or can support 5G network communication via the established communication channel. The first CP 312 and the second CP 314 can be implemented in a single chip or a single package. The first CP 312 or the second CP 314 and the processor 120 , the auxiliary processor 123 , or the communication module 190 may be formed in a single chip or a single package.
[0101] The first RFIC 322 may convert a baseband signal generated by the first CP 312 into a radio frequency signal (RF) having a frequency in a range from about 700 MHz to about 3 GHz, which is used by the first cellular network 392 (e.g., a legacy network). The RF signal may be obtained from the first cellular network 392 through the first antenna module 342 and may be pre-processed via the first RFFE 332. The first RFIC 322 may convert the pre-processed RF signal into a baseband signal that may be processed by the first CP 312.
[0102] The second RFIC 3324 may convert a baseband signal generated by the first CP 312 or the second CP 314 into a Sub6 band (eg, approximately 6 GHz or lower) RF signal used by the second cellular network 394 (hereinafter, referred to as a “5G Sub6 RF signal”).
[0103] The 5G Sub6 RF signal may be obtained from the second cellular network 394 through the second antenna module 344 and may be pre-processed via the second RFFE 334. The second RFIC 324 may convert the pre-processed 5G Sub6 RF signal into a baseband signal that may be processed by corresponding processors in the first CP 312 and the second CP 314.
[0104] The third RFIC 326 may convert the baseband signal generated by the second CP 314 into an RF signal of a 5G Above6 frequency band (e.g., from about 6 GHz to about 60 GHz) to be used by a second cellular network 394 (e.g., a 5G network) (hereinafter, referred to as a "5G Above6 RF signal"). The 5G Above6 RF signal may be obtained from the second cellular network 394 through the antenna 348 and may be pre-processed via the third RFFE 336. The third RFIC 326 may convert the pre-processed 5G Above6 RF signal into a baseband signal that may be processed by the second CP 314. The third RFFE 336 may be formed as part of the third RFIC 326.
[0105] The electronic device 301 may include a fourth RFIC 328 that is separate from the third RFIC 326, or include the fourth RFIC 328 as at least part of the third RFIC 326. In this case, the fourth RFIC 328 may convert the baseband signal generated by the second CP 314 into an intermediate frequency band (e.g., from about 9 GHz to about 11 GHz) RF signal (hereinafter, referred to as an "intermediate frequency (IF) signal"), and transmit the IF signal to the third RFIC 326. The third RFIC 326 may convert the IF signal into a 5G Above 6 RF signal. The 5G Above 6 RF signal may be received from the second cellular network 394 through the antenna 348 and may be converted into an IF signal through the third RFIC 326. The fourth RFIC 328 may convert the IF signal into a baseband signal that may be processed by the second CP 314.
[0106] The first RFIC 322 and the second RFIC 3324 may be implemented as at least part of a single chip or a single package. The first RFFE 332 and the second RFFE 334 may be implemented as at least part of a single chip or a single package. At least one of the first antenna module 342 or the second antenna module 344 may be omitted or combined with another antenna module to process multi-band RF signals.
[0107] The third RFIC 326 and the antenna 348 may be disposed on the same substrate to form a third antenna module 346. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). The third RFIC 326 and the antenna 348 may be disposed on one region (e.g., a bottom) and another region (e.g., a top) of a second substrate (e.g., a sub-PCB) provided separately from the first substrate, respectively, to form the third antenna module 346.
[0108] Arranging the third RFIC 326 and the antenna 348 on the same substrate can shorten the length of the transmission line therebetween, which can reduce the loss (e.g., attenuation) of high-frequency band (e.g., from about 6 GHz to about 60 GHz) signals for 5G network communication due to the transmission line. Therefore, the electronic device 101 can improve the communication quality with the second cellular network 394.
[0109] The antenna 348 may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. The third RFIC 326 may include a plurality of phase shifters 338 corresponding to the plurality of antenna elements as part of the third RFFE 336. The plurality of phase shifters 338 may change the phase of a 5G Above 6 RF signal to be transmitted to an external portion of the electronic device 301 (e.g., a 5G network base station) via their respective antenna elements. The plurality of phase shifters 338 may change the phase of a 5G Above 6 RF signal received from an external portion to the same or substantially the same phase via their respective antenna elements so as to perform transmission or reception via beamforming between the electronic device 301 and the external portion.
[0110] The second cellular network 394 can operate independently of the first cellular network 392 (e.g., a traditional network) (e.g., independent networking (SA)), or be connected to the first cellular network 392 (e.g., a traditional network) (e.g., as a non-independent networking (NSA)). For example, a 5G network may include an access network (e.g., a 5G access network (RAN)), but without any core network (e.g., a next-generation core (NGC)). In this case, after accessing the 5G network access network, the electronic device 301 can access an external network (e.g., the Internet) under the control of a core network (e.g., an evolved packet core) of the traditional network. Protocol information for communicating with a traditional network (e.g., LTE protocol information) or protocol information for communicating with a 5G network (e.g., new radio (NR) protocol information) can be stored in the memory 130 and can be accessed by other components (e.g., the processor 120, the first CP 312, or the second CP 314).

The first conventional antenna 451 to the third conventional antenna 455 can be used for, for example, cellular communication (e.g., 2G, 3G, 4G, or LTE), short-range communication (e.g., Wi-Fi, Bluetooth, or NFC), and / or GNSS.
[0117] The electronic device 400 includes a first antenna assembly 461, a second antenna assembly 463, and a third antenna assembly to form a directional beam. Antenna modules 461, 463, and 465 can be used in 5G networks (e.g. Figure 3The second cellular network 394), millimeter wave communication, 60 GHz communication or WiGig communication. The antenna modules 461, 463 and 465 can be arranged in the space to be spaced apart from the metal members (such as the housing 410, the internal component 473 and / or the first to third conventional antennas 451 to 455) by a predetermined interval or more.
[0118] The first antenna assembly 461 may be located at the upper left portion (+X axis), the second antenna assembly 463 may be located at the upper middle portion (-Y axis), and the third antenna assembly 465 may be located at the middle right portion (-X axis). The electronic device 400 may include additional antenna modules at additional locations, such as the middle bottom portion (Y axis), or some of the first to third antenna modules 461 to 465 may be omitted. The first to third antenna modules 461, 463, and 465 may be electrically connected to at least one CP on the main PCB 470 using a conductive line 471, such as a coaxial cable or a flexible printed circuit board (FPCB) .
[0119] Reference Figure 4B (It is along Figure 4A ), the antenna array of the first antenna component 461 can be configured so that a portion of the antenna array of the first antenna component 461 (e.g., a patch antenna array) can emit radiation toward the second board 430, and another portion thereof (e.g., a dipole antenna array) can emit radiation through the first insulator 441.

[0123] Figure 5A A cross-sectional view of an electronic device according to an embodiment is shown. Figure 5B FIG. 1 is a cross-sectional view of an electronic device according to an embodiment. Specifically, Figure 5A Shown along Figure 2A A cross-sectional view taken along line AA' of Figure 5B Shown along Figure 5B A cross-sectional view taken along line BB'.
[0124] Reference Figure 5A , the electronic device 500 includes a front plate 510, a display 520, a support member 530, a first heat transfer member 540, a PCB, a battery, and a rear plate 580. Optionally, the electronic device 500 may not include at least one of the components, or additional components may be added. The electronic device 500 also includes a heat sink 521 on the rear surface of the display 520 and a third heat transfer member 534 on the top surface of the support member 530. The PCB may form a stacked PCB structure to ensure a component mounting space corresponding to the application of a half PCB. The PCB may include a first PCB 550a on which a plurality of electronic components are mounted and a second PCB 550b at least partially overlapping the first PCB 550a and electrically connected to the first PCB 550a.
[0125] The first PCB 550a and the second PCB 550b may be electrically connected to each other through the connecting member 550c, and may be connected along a height direction (eg, parallel to Figure 2C The connecting member 550c may be provided on a surface opposite to the surface where the first heat transfer member 540 is formed, relative to the first PCB 550a. The connecting member 550c may include, for example, an interposer, a board-to-board connector, or an FPCB. At least one or more connecting members 550c may be provided to electrically connect the first PCB 550a and the second PCB 550b.
[0126] Various electronic components may be mounted on the first PCB 550a and / or the second PCB 550b.
[0127] Reference Figure 5A (It is along Figure 2A), a stacked structure of multiple electronic components and PCBs may occupy most of the space in the electronic device 500.
[0128] For example, processors 551 and 552 may be mounted on the first PCB 550a. Processors 551 and 552 may include one or more of a CPU, an AP, a GPU, an ISP, or a baseband processor (or CP). Processors 551 and 552 may be implemented as a system on chip (SoC) or a system-in-package (SiP). Various electronic components may be mounted on the first PCB 550a and / or the second PCB 550b. For example, the control circuit may also be configured as an IC chip and mounted on a PCB. The control circuit may be part of a processor or a communication module. Various other electronic components 553a may be further mounted on the first PCB 550a.
[0129] A certain electronic component 553b among the electronic components mounted on the first PCB 550a and / or the second PCB 550b can be arranged in the area between the first PCB 550a and the second PCB 550b, and another 553c can be mounted on one surface of the second PCB 550b or on the opposite surface thereof. Therefore, even when the electronic device 500 forms a semi-PCB structure, more space can be ensured for placing batteries without significantly reducing the installation space of the electronic components. At least some of the electronic components can be surrounded by shielding covers 554a and 554b, and a shielding structure can be formed on one surface of at least some of the electronic components to protect the electronic components from external electromagnetic influences.
[0130] At least one heat transfer member (eg, 540 ) may be provided inside the electronic device 500 to effectively transfer heat generated from an electronic component to a relatively low temperature portion.
[0131] like Figure 5A As shown, the electronic device 500 includes an electronic component 551, a shielding cover 554a and a shielding structure, a heat transfer member, a support member 530, a heat sink 521, a display 520 and a front plate 510 in a cross-sectional view, which are sequentially arranged toward one surface with a PCB (e.g., a first PCB 550a) used as a reference. In addition to the first heat transfer member 540 disposed between the support member 530 and the PCB (e.g., the first PCB 550a), the electronic device 500 also includes a third heat transfer member 534 disposed between the support member 530 and the display 520 as a heat transfer member. The electronic device 500 includes an electronic component 553c, a shielding cover 554b, an antenna 560, a second support member 570 and a rear plate 580 in a cross-sectional view, which are sequentially arranged toward an opposite surface with a PCB (e.g., a second PCB 550b) used as a reference.
[0132] The shielding structure includes a shielding member 555a, heat transfer materials 555b and 555d, and a metal plate 555c. The shielding structure may be disposed between the first heat transfer member 540 and the electronic component 551 to shield the electronic component 551 from surrounding electromagnetic waves, and may be thermally coupled with the first heat transfer member 540.
[0133] At least a partial area of the first heat transfer member 540 may be disposed to face at least one electronic component 551 among the plurality of electronic components mounted on the PCB 550, and at least another partial area that is bent may be disposed to face another electronic component 552 among the plurality of electronic components mounted on the PCB 550.
[0134] The electronic device 500 further includes an antenna module 591. Since the antenna module 591 is spaced apart from the heat transfer member and vertically mounted on one side surface of the electronic device 500, as shown in FIG. Figure 5A As shown, a separate heat transfer component may be provided for antenna module 591.
[0135] like Figure 5B (It is along Figure 2A As shown in the cross-sectional view taken along the line BB' of FIG. 5 , in another cross-sectional view, the battery may occupy most of the space of the electronic device 500. Since no other components (such as a PCB) other than the battery are included on one surface of the electronic device 500, a battery of a larger capacity may be advantageously placed.
[0136] Reference Figure 5B , the electronic device 500 includes a second heat transfer member 535. The second heat transfer member 535 may be disposed between the support member 530 and the battery.
[0137] like Figure 5B As shown, the electronic device 500 includes a rear plate 580 in a cross-sectional view, and the electronic device 500 includes an antenna 560, a heat sink 563, a battery, a heat transfer member, a support member 530, a heat sink 521, a display 520, and a front plate 510 arranged in sequence from the rear plate 580 to one surface. In addition to the second heat transfer member 535 provided between the support member 530 and the battery (BAT), the electronic device 500 may further include a third heat transfer member 534 provided between the support member 530 and the display 520 as a heat transfer member.
[0138] The electronic device 500 further includes an antenna module 592. Since the antenna module 592 is spaced apart from the heat transfer member and vertically mounted on one side surface of the electronic device 500, as shown in FIG. Figure 5B As shown, a separate heat transfer means may be provided for antenna module 592.
[0139] Figure 6 The heat distribution and heat diffusion direction of a component of an electronic device according to an embodiment are shown.
[0140] Reference Figure 6 , for a half-PCB structure or a stacked PCB structure (in which high-performance electronic components such as AP, memory, or communication chips are mounted), the heat generated from the electronic components when the electronic device is operating may be concentrated in a certain area (e.g., a hot spot area on one side of the PCB). For example, more heat may be generated at a processor and an antenna modem among other various electronic components mounted on the PCB in the electronic device.
[0141] Therefore, it may be beneficial to effectively diffuse / dissipate the heat concentrated in the hot spot area to a relatively low temperature portion (eg, a battery mounting area of an electronic device).
[0142] Various heat transfer elements can be used to disperse / dissipate concentrated heat, such as vapor chambers, heat pipes, shields, solid heat sheets, or liquid heat dissipation coatings. Heat transfer by various heat transfer elements can include heat conduction, heat spreading, heat diffusion, heat radiation, or other types of moving heat energy.
[0143] Figure 7 A heat sink located on the rear surface of a display according to an embodiment is shown. More specifically, Figure 7 A plan view of an electronic device 500 ′ is shown, with some components (eg, a front panel and a display) excluded from the electronic device 500 .
[0144] Reference Figure 7 , the electronic device 500 ′ includes a heat sink 521 disposed on the rear surface of the display.
[0145] The heat sink 521 is a component for dissipating heat that may be generated when the display is operated. The heat sink 521 may be attached to the rear surface of the display via an attachment member.
[0146] The heat sink 521 may be formed of a composite sheet obtained by stacking two or more sheets 521a and 521b. At least a portion of the heat sink 521 may include a carbon-based material (e.g., carbon black, graphene, carbon nanotubes, or graphite) having high thermal conductivity or heat transfer efficiency. Through holes 521c may be formed in at least a portion of the composite sheet of the heat sink 521 to improve heat dissipation efficiency.
[0147] For example, the heat sink 521 is formed of a composite sheet having a thickness of about 32 μm. At least a portion of the heat sink 521 includes graphite. Since the heat sink 521 is included in the electronic device 500 ′, the temperature measured at the front of the electronic device 500 ′ can be reduced by about 0.5° C. to 1° C. (compared to when the heat sink 521 is not used).
[0148] Figure 8 FIG. 1 shows a third heat transfer member located on the top surface of the support member according to an embodiment. Specifically, Figure 8 is a plan view of an electronic device 500 ′, from which some components (eg, a front panel and a display) are excluded.
[0149] Reference Figure 8 The third heat transfer member 534 is coupled to the top surface 530a of the support member 530 to transfer heat from one side (eg, the top end) of the support member 530 to the other side (eg, the bottom end) of the support member 530 where the temperature is relatively low.
[0150] On the top surface of the support member 530, at least a portion of the third heat transfer member 534 may be disposed in a first area ( Figure 2C S1) of the housing, and at least another portion thereof may be disposed in a second region ( Figure 2C If the third heat transfer member 534 is added, the third heat transfer member 534 may be located in the length direction of the electronic device (eg Figure 2C y) to extend from a cross section of the electronic device 500 (eg Figure 5A ) and another cross section of the electronic device 500 (eg Figure 5B )See.
[0151] The third heat transfer member 534 may have various shapes. Figure 8 As shown, the third heat transfer member 534 may be shaped to cover the top surface of the support member 530 in a portion other than the component mounting region 533 of the support member 530. The shape of the third heat transfer member 534 is not limited thereto, and various shapes may be used.
[0152] The third heat transfer member 534 may include a carbon-based material (e.g., carbon black, graphene, carbon nanotubes, or graphite) having high thermal conductivity or heat transfer efficiency. Since the electronic device 500' includes the third heat transfer member 534 having a thickness of about 62 μm and at least a portion thereof contains graphite, the temperature measured at the front of the electronic device 500 may be reduced by about 0.5°C to 1°C, and the temperature at the rear of the electronic device 500 may be reduced by about 0.25°C to 0.5°C, compared to when the third heat transfer member 534 is not included.
[0153] Fig. 9A supporting member according to an embodiment is shown. Specifically, Fig. 9 A plan view of the electronic device 500 ′ is shown, in which some components (eg, a front plate, a display, and a third heat transfer member) are excluded from the electronic device 500 .
[0154] Reference Fig. 9 , the support member 530 may be formed of a thermally conductive material in one piece. If the support member 530 includes a side frame structure 531 and a seating portion 532 , the seating portion 532 may be formed of a thermally conductive material in one piece.
[0155] In the supporting member 530, the seating portion 532' may be formed of a thermally conductive member of a different material, such as Fig. 9 shown in the left side view.
[0156] The first seating portion 532a may be formed of a member having a first thermal conductivity (e.g., a Cu plate), and the second seating portion 532b may be formed of a member having a second thermal conductivity (e.g., SUS). If the seating portion 532' is formed of members having different thermal conductivities, when heat moves from a higher temperature portion to a lower temperature portion, the heat may be blocked by a thermal barrier between heterogeneous materials, which may hinder effective heat dissipation.
[0157] Therefore, the support member 530 is formed of an integral thermally conductive material (e.g., an all-aluminum (Al) alloy) having high heat transfer efficiency, preventing a thermal barrier between heterogeneous materials from hindering heat transfer. Using the support member 530 formed of an all-metal alloy (e.g., an all-Al alloy) can reduce the temperature measured at the front of the electronic device 500 by about 0.5°C to 1.5°C and reduce the temperature at the rear of the electronic device 500 by about 0.25°C to about 0.75°C, compared with an electronic device having a thermally conductive member of heterogeneous materials (e.g., Fig. 9 compared to the electronic device shown on the left hand side of FIG.
[0158] Fig.10 A second heat transfer member 535 is shown located on the rear surface of the support member (or on the top surface of the battery) according to one embodiment. Specifically, Fig.10 A plan view of an electronic device 500 ′ is shown, with some components excluded from the electronic device 500 .
[0159] The second heat transfer member 535 may be a component coupled to the bottom surface of the support member 530 to transfer heat concentrated on one side (e.g., the top end) of the support member 530 to the other side (e.g., the bottom end) of the support member 530 where the temperature is relatively low. Alternatively, the second heat transfer member 535 may be a structure coupled to the top surface of the battery. The second heat transfer member 535 may be disposed between the support member 530 and the battery, and the second heat transfer member 535 may transfer heat generated from the PCB 550a to one end of the battery away from the PCB 550a.
[0160] At least another portion of the second heat transfer member 535 may be disposed on the top surface of the battery or the rear surface of the support member 530 in contact with the second region ( Figure 2C The position corresponding to S2).
[0161] The second heat transfer member 535 may have various shapes. Fig.10 As shown, the opening may be formed in a portion of the surface facing the battery. The second heat transfer member 535 may be shaped to be narrowed and elongated along the length direction while bypassing the area where the battery is placed in the support member 530 (e.g., the battery attachment member application area). The second heat transfer member 535 may be shaped to extend to pass through an area close to the center and edge of the battery on the top surface of the battery. The shape of the second heat transfer member 535 is not limited thereto, and other various shapes may be used.
[0162] The second heat transfer member 535 may include a carbon-based material (e.g., carbon black, graphene, carbon nanotubes, or graphite) having high thermal conductivity or high heat transfer efficiency. Since the electronic device 500' includes the second heat transfer member 535 of about 60 μm thickness and at least a portion of the second heat transfer member 535 contains graphite, the temperature measured at the front may be reduced by about 0.5°C to 1°C compared to when the second heat transfer member 535 is not included.
[0163] Fig.11 A first heat transfer member is shown located on the top surface of at least one electronic component mounted on a PCB according to an embodiment. Specifically, Fig.11 A plan view of an electronic device 500 ′ is shown, with some components excluded from the electronic device 500 .
[0164] Reference Fig.11 The first heat transfer member 540 may be formed to cover at least a portion of the top surface of the PCB 550a where heat is concentrated. The first heat transfer member 540 may be a member that quickly diffuses heat generated from electronic components mounted on the first PCB 550a and concentrated at a portion to a relatively low temperature area.
[0165] At least a portion of the first heat transfer member 540 may be disposed on the top surface of the first PCB 550a in contact with the first region ( Figure 2C The position corresponding to S1).
[0166] The first heat transfer member 540 may have various shapes. Fig.11 As shown, when viewed from above the top surface, the first heat transfer member 540 may be L-shaped as a whole, but is not limited thereto. The shape of the first heat transfer member 540 may vary according to the types and arrangement of electronic components on the PCB 550a.
[0167] The first heat transfer member 540 may include a steam chamber. The steam chamber may have at least a portion facing a surface (e.g., a rear surface of the first heat transfer member 540) where heat is dissipated from the electronic components mounted on the first PCB 550a. The first heat transfer member 540 may receive heat through the rear surface. Since the interior of the first heat transfer member 540 is a vacuum, the heat received from the electronic components may be rapidly diffused in the horizontal direction.
[0168] For example, the first heat transfer member 540 may be treated as an internal vacuum and may be a heat conductor filled with a working fluid. If heat is applied to any part of the first heat transfer member 540, the liquid working fluid may evaporate, resulting in a pressure difference. The pressure difference allows the gaseous working fluid to move relatively quickly to a relatively low temperature area. This principle may be used for the first heat transfer member 540.
[0169] The first heat transfer member 540 may be used together with at least one of the second heat transfer member 535 and / or the third heat transfer member 534. Since the first heat transfer member 540 is disposed between the support member 530 and the first PCB 550a and the second heat transfer member 535 and / or the third heat transfer member 534 cover the area where the first heat transfer member 540 is not disposed, heat concentrated on one side (e.g., the top end) of the support member 530 may be transferred to the opposite side (e.g., the bottom end) of the support member 530 where the temperature is relatively low. This results in heat generated from the PCB being transferred to the end of the battery located away from the PCB.
[0170] Fig.12 A wireless charging antenna and a heat sink disposed between the wireless charging antenna and a battery according to an embodiment are shown.
[0171] Reference Fig.12If the electronic device includes a wireless charging antenna 560, the temperature around the wireless charging antenna 560 may soar when the battery is charged. A heat sink 563 may be provided near the wireless charging antenna 560 to transfer the generated heat to a relatively low temperature portion. The heat sink 563 may be provided between the wireless charging antenna 560 and the battery.
[0172] The shape of the wireless charging antenna 560 may vary depending on the specifications of the antenna, the arrangement relationship with other components in the electronic device, and / or the shape of the shielding structure.
[0173] When the wireless charging antenna 560 is formed as a flat plate, as Fig.12 As shown, the heat sink 563 may extend to a portion of the wireless charging antenna 560 that does not affect signal transmission / reception efficiency (eg, the segmented portion 561 or the bent portion 562 ), thereby improving heat transfer efficiency.
[0174] Fig.13 1 shows a second supporting member according to an embodiment. Specifically, Fig.13 A rear view of the electronic device 500 ′ is shown, with some components excluded from the electronic device 500 .
[0175] Reference Fig.13 , the second support member 570 can be added adjacent to the rear plate. The second support member 570 can at least partially include an injection molded material. For example, a partially separated portion of the second support member 570 can be formed by an injection molded material, while other separated portions can be formed by a cladding plate (or cladding metal). As another example, the second support member 570 can be a single structure formed by dual injection molding.
[0176] If it is difficult to implement the injection molding material at the lower portion of the PCB (eg, the lower portion of the second PCB 550 b ) due to the PCB stack structure, the second support member 570 may include a cover plate at the lower portion where the injection molding material is difficult to implement.
[0177] The entire second support member 570 may be formed of a cladding plate. Typically, the back plate is substantially opaque and may include an injection molded material or may partially include a heat sink such as SUS. Since the heat sink is implemented as a cladding plate, the heat transfer efficiency may be improved. The cladding plate may include a first material in the core and a second material in an upper layer and / or lower layer surrounding the core.
[0178] Since Cu is used as the core of the cladding plate and SUS is used as the surrounding layer (e.g., SUS / CU / SUS cladding plate), thermal conductivity can be improved several times (e.g., 0.04 cal / sec for SUS and 0.35 cal / sec for cladding) compared to when no cladding plate is used.
[0179] If the second support member 570 is formed of a cladding plate, the temperature measured at the rear of the electronic device may be reduced by about 0.5° C. to about 1° C.
[0180] Fig.14 An arrangement of an electronic component, a shielding structure, and a first heat transfer member according to an embodiment is shown.
[0181] Reference Fig.14 , various electronic components can be mounted on the first PCB 650a. The electronic components can have various shapes, sizes and specifications according to their functions. When the electronic components perform various functions of the electronic device, they can generate different amounts of heat. Typically, more heat can be generated from electronic components (such as processors) used to control and manage other electronic components. The processor may include a first processor 651 and a second processor 652. The first processor 651 and the second processor 652 may have different levels. For example, the first processor 651 may be higher than the second processor 652.
[0182] The first heat transfer member 640 may be formed to face top surfaces of the first and second processors 651 and 652 .
[0183] The first heat transfer member 640 may be indirectly connected to the first processor 651 and the second processor 652 via at least one shielding structure 655 , rather than directly contacting the first processor 651 and the second processor 652 .
[0184] At least some of the electronic components 651 and 652 mounted on the first PCB 650a may be surrounded by the shield case 654a, and a shielding structure may be provided on one surface of at least some of the electronic components to shield electromagnetic waves.

[0186] The shielding structure may include: a shielding member 655a, which is arranged to surround the outer surface of the shielding cover 654a and an opening formed in the surface of the shielding cover 654a corresponding to the electronic component and is electrically connected to the shielding cover 654a; a metal plate 655c, which is arranged on the shielding member 655a, covers the opening, and is electrically connected to the shielding member 655a; a first heat transfer material 655b, which is arranged in the opening to contact the electronic component and the metal plate 655c; and a second heat transfer material 655d, which is arranged between the metal plate 655c and the first heat transfer member 640 to contact the metal plate 655c and the first heat transfer member 640.
[0187] The shielding member may include a shielding film and a polyurethane (PU), at least a portion of which is surrounded by the shielding film. The shielding film may be a conductive film based on nanofibers. The shielding structure generated by surrounding the PU foam with a nanofiber shielding film may be referred to as a nanofoam. The first heat transfer material 655b and 655d may include a liquid or solid thermal interface material (TIM). The solid or liquid TIM may include, for example, graphite, carbon nanotubes (CNT), natural recyclable materials, silicone, silicon or other high thermal conductivity materials.
[0188] Heat generated from the electronic components 651 and 652 may be thermally coupled with the first heat transfer member 640 via at least a portion (eg, 655 b , 655 c , and 655 d ) of the shielding structure.
[0189] The first heat transfer member 640 may be stepped corresponding to the step between the first processor 651 and the second processor 652. However, the step formed in the first heat transfer member 640 does not need to be the same in height or level as the step between the first processor 651 and the second processor 652, but may vary according to various combinations and shapes of heat transfer materials. At least one partial area of the first heat transfer member 640 may be formed to face the first processor 651, and at least another partial area of the first heat transfer member 640 (which is bent) may be formed to face the second processor 652.
[0190] The electronic device may further include an attaching member 656 between the shield case 654 a and the shield member and / or between the first heat transfer member 640 and the support member 630 .
[0191] Fig.15A A perspective view is shown of a first heat transfer member according to an embodiment. Fig. 15B A front view of a first heat transfer member according to an embodiment is shown. Fig. 15C A side view of a first heat transfer member is shown according to an embodiment.

[0193] The first heat transfer member 640 includes a first flat portion 641 and a second flat portion 642 extending from the first flat portion 641 and bent to be stepped from the first flat portion 641 .
[0194] Reference FIG. 15A to FIG. 15C The bent portion 643 of the first heat transfer member 640 may have at least one of the shapes of “┐”, “L”, or “Z”. The first heat transfer member 640 may have various other bent shapes other than those listed above.
[0195] although FIG. 15A to FIG. 15C The first heat transfer member 640 is shown to have two bent portions 643, but the present disclosure is not limited thereto. The first heat transfer member 640 may include a single bent portion 643 or three or more bent portions 643. In addition to the first flat portion 641 and the second flat portion 642, the first heat transfer member 640 may further include other flat portions stepped from each of the first flat portion 641 and the second flat portion 642.
[0196] A specific shape of the first heat transfer member 640 may vary according to the kind and size of electronic components disposed on the rear surface 640 b of the first heat transfer member 640 and the amount of heat generated from the electronic components.
[0197] Fig.16 An antenna module and a low dielectric constant heat sink according to an embodiment are shown.
[0198] Reference Fig.16 , the battery and various electronic components can be placed in the internal space of the electronic device. In addition, the antenna modules 791, 792 and 793 and the heat sinks 782 and 783 are positioned adjacent to each other in the internal space of the electronic device.
[0199] The antenna modules 791 , 792 , and 793 may include a PCB formed of a plurality of conductive layers, an RFIC and a PMIC disposed on one surface of the PCB, and an antenna radiator disposed on an opposite surface of the PCB or disposed inside the PCB.
[0200] The antenna modules 791, 792, and 793 may form various directional beams. The first antenna module 791 and the second antenna module 792 may be arranged (vertically mounted) so that one surface of the antenna radiator faces the side surface of the electronic device so as to radiate electromagnetic waves to the side surface. The first antenna module 791 and the second antenna module 792 may be spaced apart from each other to radiate electromagnetic waves in different directions (e.g., in a vertical direction or a relative direction). The third antenna module 793 may be arranged (horizontally mounted) so that one surface of the antenna radiator faces the rear plate 780 so as to radiate electromagnetic waves to the rear surface of the electronic device.
[0201] The heat sinks 782 and 783 may be provided between the first support member and the rear plate 780. The heat sinks 782 and 783 may be attached to the rear plate 780. The heat sinks 782 and 783 may be arranged at positions corresponding to the antenna modules 791, 792, and 793. For example, at least a partial area of the first heat sink 782 may face the first antenna module 791 and the third antenna module 793, and at least a partial area of the second heat sink 783 may face the second antenna module 792.
[0202] The first heat sink 782 may be disposed in the top end region of the rear plate 780 and may cover one surface of the first antenna module 791 and the third antenna module 793 facing the rear plate 780. The first heat sink 782 may be formed to surround at least a portion of the periphery of the opening 781 (for exposing, for example, a camera). As another example, the first heat sink 781 may be integrally formed into a partially curved '┌' or '┐'.
[0203] The second heat sink 783 may be spaced apart from the first heat sink 782. For example, the second heat sink 783 may be disposed in the bottom middle region of the rear plate 780 and may cover the surface of the second antenna module 792 facing the rear plate 380. As another example, the second heat sink 783 may extend from the region where the second antenna module 792 is disposed to the lower end of the rear plate 380. The second heat sink 783 may be integrally shaped as a partially curved '└' or '┘'.
[0204] Despite Fig.16 Two heat sinks 782 and 783 are shown in FIG. 1 , but the present disclosure is not limited thereto. For example, three or more separate heat sinks may be provided to cover three antenna modules.
[0205] The heat sinks 782 and 783 may include an adhesive resin and a ceramic filler. The heat sinks 782 and 783 may also include a high heat dissipation filler. The high heat dissipation filler may be coated with a low dielectric constant insulating material.
[0206] The thickness of the heat sinks 782 and 783 may be in the range from 50 μm to 1000 μm.
[0207] At least one heat sink may be spaced apart from the at least one antenna module and attached to the housing.
[0208] Fig.17A A mounting structure of a vertically mounted antenna module according to an embodiment is shown. Fig. 17B A vertically mounted antenna module is shown according to an embodiment. Fig. 17C A cross-sectional view showing a mounting structure of a vertically mounted antenna module according to an embodiment.
[0209] Reference Fig.17A , the first antenna module (eg Fig.16 antenna module 791) and a second antenna module (eg Fig.16 The antenna module 792) can be a vertically mounted antenna module.
[0210] The vertically mounted antenna module includes a PCB 791b and a radiator 791a disposed on the PCB 791b to face the outside of the electronic device.
[0211] RFIC, PMIC, connectors, and other various electronic components may be disposed on the PCB 791b of the vertically mounted antenna module. The antenna radiator 791a may be disposed on one surface of the PCB 791b.
[0212] The antenna radiator 791a may be a plurality of conductive plates or an antenna array formed of a radiating conductor, and the antenna, which may have various structures, may be at least one of a patch type antenna or a dipole type antenna, for example.
[0213] The RFIC can be electrically connected to the antenna radiator and can receive a communication signal with a specified frequency through a wireless transceiver (e.g., an RF transceiver), or send a received communication signal to the RF transceiver. For example, the RFIC can perform wireless communication using the multiple conductive plates or radiating conductors under the control of the processor. The RFIC can receive control signals and power from the power management module and the processor to process communication signals received from the outside or to be sent to the outside. The RFIC may include a switching circuit for separating the transmit signal and the receive signal, or various amplifiers or filters for improving the quality of the transmit signal or the receive signal. As described above, the RFIC mounted on the board 791b of the vertically mounted antenna module can be a heat source that generates heat when the electronic device is running. Although not described separately, the PMIC can also be a heat source that generates heat when the electronic device is running.
[0214] Reference Fig. 17C , the vertically mounted antenna module 791 may be spaced apart from the heat transfer member. Therefore, it is necessary to transfer, diffuse, disperse or release the heat generated from the modular heat source installed in the electronic device separately from the heat transfer member according to the above-described embodiment.
[0215] according to Fig. 17C In the illustrated embodiment, a heat sink may be placed adjacent to the vertically mounted antenna module to reduce the heat concentrated around the antenna module. The first heat sink 782 may be spaced a specified distance from a surface of the first antenna module 791 facing the rear plate 780. The space may be filled with air, thereby allowing the heat generated from the hot spot area to be evenly diffused to the first heat sink 782.
[0216] Reference Fig. 17B and Fig. 17C, the vertically mounted antenna module 791 may be vertically mounted on the support member 730 using a frame 791c, and may be screwed and fixed using holes located in both side surfaces of the frame 791c. If the frame 791c is thermally coupled to the support member 730, heat from the modular heat source may be transferred, diffused, dispersed, or released outwardly. A heat transfer material 791d (e.g., TIM) may be additionally formed between the at least one antenna module and the frame 791c, thereby expanding the thermal contact area.
[0217] use Fig.17A , Fig. 17B and Fig. 17C configuration, the temperature measured on the electronic device side can be reduced by about 0.5°C to about 1°C, and the temperature of the board on which the RFIC is mounted can be reduced by about 8°C to 12°C.
[0218] Fig.18 A PCB of an antenna module is shown mounted horizontally according to an embodiment.
[0219] Reference Fig.18 , at least one antenna module includes a PCB 793', which is a stack of multiple layers 793a, 793b and 793c facing the placement portion of the support member, and a via 793d can be formed through at least a portion of the multiple layers in at least a partial area of the PCB 793'. The RFIC can be mounted on the PCB 793', and the heat from the PCB 793' can be reduced via the via 793d.
[0220] The surface of PCB 793' facing the rear surface of antenna module 793 can connect the metal layer of the PCB included in antenna module 793 to the rear surface of module 793 while bypassing the insulating layer of the PCB included in antenna module 793. Therefore, heat dissipation can be achieved using the metal layer of the PCB.
[0221] By using Fig.18 configuration, the temperature of a board on which an RFIC is mounted in an electronic device can be reduced by approximately 2°C to 3°C.
[0222] Fig.19 A vertically mounted antenna module and frame are shown according to one embodiment.
[0223] Reference Fig.19 , the frame 792c of the vertically mounted antenna module 792 can be typically formed of an injection molded material. For example, the frame 792c can be formed by processing one side of the support member 730 (e.g., a bracket) during the process of manufacturing the housing of the electronic device. Fig. 9The method of improving the heat transfer efficiency by forming a support member 730 of an integral all-metal alloy (for example, an all-Al alloy), the frame 792c of the vertically mounted antenna module 792 can be formed of an integral material (for example, an all-Al alloy) like the support member 730, thereby improving the heat transfer efficiency around the antenna module.
[0224] By using Fig.19 configuration, the temperature measured on the electronic device side can be reduced by about 0.5°C to about 2.5°C, and the temperature of the board on which the RFIC is mounted can be reduced by about 1.5°C to 3°C.

Specifically, Fig. 20 The upper part shows the simulation results before applying the heat transfer member according to the embodiment, Fig. 20 The lower part of shows the simulation results after applying the heat transfer member according to the embodiment.
[0226] Reference Fig. 20 The use of the heat dissipation member and the electronic device including the same can effectively transfer the heat generated from various electronic components of the electronic device to a relatively low temperature portion.
[0227] Furthermore, the electronic device may effectively release heat generated from the antenna module (eg, RFIC or PMIC) using a heat sink and / or a heat transfer material positioned adjacent to the antenna module.
[0228] The electronic device according to various embodiments may be one of various types of electronic devices.
