The disclosure relates to electronic devices, for example, electronic devices including a heat dissipation structure for moving, dispersing and/or dissipating heat generated internally.
Generally, the electronic device may refer to a device performing a particular function according to its equipped program, such as a home appliance, an electronic scheduler, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/sound device, a desktop PC or laptop computer, a navigation for automobile, etc. For example, electronic devices may output stored information as voices or images. As electronic devices are highly integrated and high-speed, high-volume wireless communication becomes commonplace, mobile communication terminals are recently being equipped with various functions. For example, an electronic device comes with the integrated functionality, including an entertainment function, such as playing video games, a multimedia function, such as replaying music/videos, a communication and security function for mobile banking, and a scheduling or e-wallet function.
As the performance of electrical elements equipped with processors or communication modules, such as integrated circuit chips, enhances dramatically, an environment in which these various functions may be integrated into one electronic device is provided. Enhancement in the performance of electrical elements not only provides an environment in which various functions may be mounted on a single electronic device, but also enhance data communication and processing speeds.
The above-described information may be provided as related art for the purpose of helping understanding of the disclosure. No claim or determination is made as to whether any of the foregoing is applicable as background art in relation to the disclosure.
According to an example embodiment of the disclosure, there may be provided an electronic device comprising: a housing forming an exterior of the electronic device, a printed circuit board on which at least one component is disposed, and a heat dissipation member contacting the at least one component or contacting the at least one component through a thermally conductive material, and including a first plate, a second plate and a wick. The wick may be disposed on a second plate inside the heat dissipation member and include a first portion and a second portion. The first portion may be thicker than the second portion.

According to an example embodiment of the disclosure, there may be provided an electronic device comprising: a housing including a first surface and a second surface facing in a direction opposite to the first surface, a support accommodated in the housing between the first surface and the second surface, and a heat dissipation member supported by the support, and including a heat receiving portion including a portion configured to vaporize a working fluid based on heat being absorbed from a heat source disposed in the electronic device, a heat dissipation portion configured to liquify the working fluid based on the heat being discharged, and a wick disposed on the heat receiving portion and the heat dissipation portion.

The foregoing and other aspects, features, and/or advantages of certain embodiments of the present disclosure will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Throughout the drawings, like reference numerals may be assigned to like parts, components, and/or structures.
Heat generated from electrical element(s), such as integrated circuit chips, may impair the operating environment of electronic devices. As the performance of various electrical elements enhances and the degree of integration of electronic devices increases, and/or the capacity of image or sound data increases, deterioration of the operating environment due to heat generation may increase. Integrated circuit chips equipped with circuit devices, such as processors, may generate more heat than other electrical elements. Further, as development of electronic devices is directed to reducing the thickness, if more heat is generated in a narrower area, and/or the generated heat is accumulated in the electronic device, the operation environment of the electrical component(s) may further worsen. In order to enhance heat dissipation performance of the electronic device, a heat dissipation member (e.g., vapor chamber) that performs cooling using a phase change between liquid and gas may be employed. However, even if the heat dissipation performance of the electronic device is partially enhanced, enhancement for the temperature of the heat source may not be obtained due to the heat resistance between the heat dissipation member and the heat source (e.g., the processor).
Embodiments of the disclosure aim to address the foregoing issues and/or drawbacks and provide advantages described below, by providing an electronic device including a heat dissipation structure for moving, dispersing, and/or dissipating internally generated heat.
Embodiments of the disclosure may provide an electronic device including a heat dissipation member with reduced heat resistance between heat dissipation member and heat source (e.g., a processor).

According to an embodiment, the at least one component 241 may be disposed inside the shield can 249, thereby providing an electromagnetically isolated environment. Since the shield can 249 surrounds at least a portion of the at least one component 241, the shield can 249 may serve to shield electromagnetic waves generated from the at least one component 241. In an embodiment, as the shield can 249 is disposed on the heat transfer path to the heat dissipation member 230 as the at least one component 241, the heat transfer efficiency may be reduced.

According to an embodiment, the shielding sheet 245 may be pre-formed to cover components having different heights and/or the shield can 249, and may provide a structure including an inclined surface or a curved surface through the pre-forming. As another example, the shielding sheet 245 may provide a three-dimensional shape (e.g., a conformal type) structure to encapsulate components of various sizes and shapes disposed on the printed circuit board 240 into one sheet of self-adhesive vinyl, thereby providing a shielding function. According to an embodiment, the shielding sheet 245 may include a shielding film. According to an embodiment, the shielding sheet 245 may be a sheet formed of a metallic material such as copper (Cu), with an adhesive attached thereto. According to an embodiment, the shielding film may be formed of a fiber film having a nanostructure to shield electromagnetic waves. The fiber film may be formed to be thin and long by processing the fibers based on an electrospinning method, and the fibers thus formed may be plated with copper (Cu), then with nickel (Ni), and finally again with copper (Cu). In addition to the shielding function, the shielding sheet 245 may provide a heat transfer function for transferring heat that may be generated by the at least one component 241 to the outside of the at least one component 241. According to an embodiment, the shielding sheet 245 may include a conductive adhesive film. According to an embodiment, the shielding sheet 245 may be formed by stacking a plurality of layers.
