ELECTRONIC DEVICE INCLUDING SUPPORT PLATE

BACKGROUND
Technical Field

Certain embodiments of the disclosure relate to an electronic device including a support plate.

Description of Related Art

Owing to development of information and communication technology and semiconductor technology, the world has seen rapid increase in the distribution and usage of various types of electronic devices. Particularly, recent electronic devices provide a diversity of communication functions and are highly portable.

An electronic device refers to a device that executes one or more functions according to installed programs, such as an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/audio player, a desktop/laptop computer, a vehicle navigation device, and a home appliance. For example, such electronic devices may output stored media information visually or audibly. As electronic devices increase in functional integration, and as ultra-high-speed and large-capacity wireless communication becomes increasingly common, a single electronic device, such as a mobile communication terminal, may now implement a diversity of functions previously performed by multiple devices. For example, a single electronic device, such as a portable terminal, may include a communication function, an entertainment function (e.g., videogames), a multimedia function such as music/video playback, communication and security functions, such as mobile banking and schedule management, and an electronic wallet for executing electronic payments. All these functions are often integrated into one electronic device. Such electronic devices are also miniaturized so that users may conveniently carry them.

Electronic devices equipped with a communication function, such as portable terminals, may be reduced in size and weight to maximize portability and convenience, and have multiple components disposed in a small housing space, which nevertheless may operate at high performance levels. In such devices, heat is generated from operation of the main components, such as an application processor (AP)/communication processor (CP), to achieve the desired levels of product performance. A heat dissipation structure is often included to reduce interior temperatures by diffusing the heat to an external environment.

The heat dissipation structure may be formed so as to include a plate serving as a body, a heat pipe, and a heat sink, all of which may be coupled with each other. In this case, as the size of the plate increases, it may be difficult to retain a requisite degree of uniform flatness. However, when flatness is not uniform, the heat dissipation structure may be separated from a heat-generating component during installation, and/or may cause the component to warp due to insufficient cooling.

When the heat dissipation structure is assembled on a circuit board on which a heat generating component (e.g., an application processor (AP), a communication processor (CP), or a power management integrated circuit (PMIC)) or a shield can is disposed, there may be insufficient coupling with the circuit board at a specified position, due to the lifting phenomenon caused by different flatness of the heat dissipation structure itself, and/or warping caused by heat generated from the heat generating component. When lifting occurs, heat concentration in the component may result, because of insufficient heat dissipation. For example, a “hot spot” phenomenon may occur, and/or a shielding may be weakened. Heat dissipation may be reduced or ineffective for a heat dissipation structure, such as a shielding wall.

SUMMARY

According to certain embodiments of the disclosure, an electronic device is provided that includes a plate that compensates for the flatness of a heat dissipation module.

According to certain embodiments of the disclosure, an electronic device may be provided that includes a plate that reinforces a shielding function by increasing a bonding force between a heat dissipation module and a circuit board.

The objects to be achieved in the disclosure are not limited to what has been described above, and may be variously extended without departing from the scope of the disclosure.

According to certain embodiments of the disclosure, an electronic device includes: a first housing; a display disposed within the first housing; a printed circuit board disposed within the first housing; a heat dissipation plate disposed to face the printed circuit board; at least one heat pipe disposed between the heat dissipation plate and the printed circuit board; and a support plate disposed between the printed circuit board and the heat dissipation plate, wherein the support plate includes: a first portion disposed so as to contact with at least a part of the at least one heat pipe; and a second portion extending from the first portion in a second direction perpendicular to a first direction in which the at least one heat pipe is disposed, the second portion coupled to at least a part of the heat dissipation plate.

According to certain embodiments of the disclosure, a support plate includes: a first portion disposed in contact with at least a part of at least one heat pipe, and a second portion extending from the first portion in a second direction perpendicular to a first direction along which the at least one heat pipe is disposed, the second portion coupled to at least a part of a heat dissipation plate.

According to certain embodiments of the disclosure, because a heat dissipation module and a printed circuit board are fixedly in close proximity with each other, a diffusion of heat generated from a heat source may be increased, and a cooling effect may be improved.

According to certain embodiments of the disclosure, because the heat dissipation module and a shield can of the printed circuit board are fixed so as to be in close contact with each other, lifting of the heat dissipation module away from the heat generating component may be reduced or alleviated, thereby improving a shielding function.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (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 legacy cellular network, a 5G network, a next-generation communication 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 subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101.

FIG. 5A is a plan view illustrating a heat dissipation module according to certain embodiments of the disclosure. FIG. 5B is a perspective view illustrating the heat dissipation module according to certain embodiments of the disclosure.

Referring to FIGS. 5A and 5B, an electronic device (e.g., the electronic devices 101 and 400 of FIGS. 1 to 4) may include a heat dissipation module 500. The heat dissipation module 500 may include at least one of a heat dissipation plate 510, heat pipes 520a and 520b, heat sinks 530a and 530b, or a sidewall structure 550.

According to certain embodiments, the heat dissipation module 500 may be formed in a structure corresponding to a shape of a circuit board included in the electronic device 101. At least a part of the heat dissipation plate 510 may be coupled to at least some parts of the heat pipes 520a and 520b. At least some parts of the heat pipes 520a and 520b may be coupled to at least some parts of the heat sinks 530a and 530b. For example, at least one heat pipe 520a or 520b may be disposed at the center of the heat dissipation plate 510. The heat sinks 530a and 530b may be disposed at both ends of the at least one heat pipe 520a or 520b.

According to certain embodiments, the heat pipes 520a and 520b may diffuse heat generated from a heat source or a shield can included in the circuit board contacting with the heat pipes 520a and 520b, and the heat dissipation plate 510 may fix the heat pipes 520a and 520b to be in contact with the heat source or the shield can. The heat sinks 530a and 530b may diffuse heat transferred from the heat pipes 520a and 520b. The heat dissipation plate 510 may include at least one fastening hole 540 for connection to the circuit board, and may be coupled to the circuit board by fixing a screw or a nail in the fastening hole 540. The sidewall structure 550 may be coupled with a clip structure (e.g., a clip structure 810d of FIGS. 8A and 8B) disposed on the circuit board (e.g., a circuit board 800 of FIG. 8A). The sidewall structure 550 may be coupled with the circuit board to reinforce functional shielding in blocking noise or electromagnetic waves.

According to certain embodiments, the heat dissipation plate 510 and the heat pipes 520a and 520b may be formed of a metal material with a sufficient degree of heat transference. For example, the heat dissipation plate 510 and the heat pipes 520a and 520b may be formed of copper, aluminum, or stainless steel. Flatness may further improve the operational qualities of the heat dissipation plate 510 and the heat pipes 520a and 520b. Error tolerance in flatness for long parts of the heat pipes 520a and 520b and the heat dissipation plate 510 should be about 0.6 mm or less, and error tolerance for short parts thereof should be about 0.3 mm or less, so as to prevent lifting or warping after coupling with the circuit board. However, as the size of the heat dissipation module 500 increases, it may become difficult to manage flatness during manufacturing, and further, manufacturing resource waste may increase due to losses at the heat dissipation module when manufactured with a flatness outside the accepted tolerance range. Therefore, there is a need to devise a new configuration to compensate for and/or implement flatness.

According to certain embodiments, the shield can 1015 may be formed so as to surround at least a part of the electronic component 1010. The shield can 1015 may be coupled with one surface (e.g., one surface facing the +Z direction) of the circuit board 1005. At least a part of the surface of the circuit board 1005 may be coupled with the shield can 1015 by solder pasting.

According to an embodiment, the shielding structure 1020 may be disposed on one surface of the electronic component 1010, and serve to prevent interference caused by electromagnetic waves generated from the electronic component 1010. This interference may negatively affect other electronic components (not shown) disposed inside the electronic device. According to certain embodiments, the shielding structure 1020 may be the same as the shield can 1015 or may be included in a part of the shield can 1015. For example, when the shielding structure 1020 is the same as the shield can 1015, the shielding structure 1020 may be the top surface of the shield can 1015, without inclusion in the shield can 1015.

According to certain embodiments, the shielding structure 1020 may be disposed on at least a part of the shield can 1015 or included in a part of the shield can 1015. The shielding structure 1020 may provide a shielding function against electromagnetic waves that may be generated from the electronic component 1010 and a heat conduction function for transferring heat that may be generated from the electronic component 1010 to the outside of the electronic component 1010.

According to certain embodiments, the heat dissipation plate 1035 and the heat pipe 1030 may be disposed in the +Z-axis direction of the shield can 1015 surrounding the electronic component 1010, or the shielding structure 1020, and serve to diffuse heat generated from the electronic component 1010 to the external environment of the electronic device. In addition, the sidewall structure 1070 included in the heat dissipation plate 1035 may be disposed so as to surround at least a part of the electronic component 1010, the shield can 1015, and/or the shielding structure 1020, and supplement the shielding function against electromagnetic waves generated from the electronic component 1010. According to an embodiment, the sidewall structure 1070 may be coupled to a clip structure (not shown here) (e.g., the clip structures of FIGS. 8A and 8B) disposed on at least one surface of the circuit board 1005.

The support plate 1025 according to certain embodiments of the disclosure may be provided between the heat dissipation plate 1035 and the heat pipe 1030, and the electronic component 1010, the shielding structure 1020, and/or the shield can 1015, and thus the heat dissipation plate 1025 and the heat pipe 1030 may be fixedly disposed so as to be in close contact with the electronic component 1010. Due to the resulting rapid diffusion of heat generated from the electronic component 1010 to the external environment of the electronic device, the temperature local to the electronic component 1010 may be effectively lowered.
