In one embodiment, the processor (510) may, for example, execute software (e.g., a program) to control at least one other component (e.g., a hardware or software component) of an electronic device (200) connected to the processor (510) and may perform various data processing or operations.

[0066] According to one embodiment, as illustrated in FIGS. 5a and 5b, the first heat dissipation sheet (610) and the second heat dissipation sheet (620) are arranged so that at least a portion overlaps with the area (A1) corresponding to the processor (510), the area (A3) corresponding to the printed circuit board (520), and the area (A4) corresponding to the first battery (291) on the first surface (211) of the first housing (210), thereby dissipating heat generated from the processor (510), the printed circuit board (520), various electronic components and / or the first battery (291) placed on the printed circuit board (520) to the surroundings. For example, the first heat dissipation sheet (610) and the second heat dissipation sheet (620) may overlap at least partially with the placement areas (e.g., A1, A3, A4) of the processor (510), printed circuit board (520), and the first battery (291) when the flexible display (230) is viewed vertically (e.g., when viewed in the Z-axis direction of FIG. 5a).

[0067] In one embodiment, the area (A1) corresponding to the processor (510), the area (A3) corresponding to the printed circuit board (520), and the area (A4) corresponding to the first battery (291) may be part of the first surface (211) of the first housing (210) corresponding to the area where the processor (510), printed circuit board (520), and first battery (291) are disposed on the second surface (212) of the first housing (210).

[0068] In one embodiment, a first heat dissipation sheet (610), a second heat dissipation sheet (620), and a flexible display (230) may be laminated in order on a first surface (211) of a first housing (210) (e.g., a surface of a first support member (261). For example, after the first heat dissipation sheet (610) is placed on the first surface (211) of the first housing (210), the second heat dissipation sheet (620) and the flexible display (230) may be placed sequentially. Accordingly, heat generated from the processor (510), the printed circuit board (520), the electronic components placed on the printed circuit board (520), and / or the first battery (291) can be conducted to the second side (212) of the first housing (210) (e.g., the other side of the first support member (261)) - the first side (211) (e.g., one side of the first support member (261)) - the first heat dissipation sheet (610) - the second heat dissipation sheet (620) and spread to the surroundings.

[0069] In the above description, the first surface (211) of the first housing (210) may be a surface facing the front of the electronic device (200) as one surface of the first support member (261) constituting the first housing (210). The second surface (212) of the first housing (210) may be a surface facing the back of the electronic device (200) as the other surface of the first support member (261). For convenience of explanation, the first surface of the first support member (261) will be described as the first surface (211) of the first housing (210), and the second surface (212) of the first housing (210) will be described as the other surface of the first support member (261).

[0070] In one embodiment, referring to FIG. 5a and FIG. 8, a recess (500) in which a first heat dissipation sheet (610) is disposed may be formed on a first surface (211) of a first housing (210). In one embodiment, the recess (500) may be an indented groove forming a step with respect to the first surface (211) of the first housing (210). In one embodiment, the recess (500) may be formed with a size corresponding to that of the first heat dissipation sheet (610).

[0071] In one embodiment, the area (A1) corresponding to the processor (510), the area (A3) corresponding to the printed circuit board (520), and the area (A4) corresponding to the first battery (291) on the first surface (211) of the first housing (210) may be located within the recess (500). In one embodiment, the first heat dissipation sheet (610) may be received in the recess (500) and adhered to the first surface (211) of the first housing (210) through an adhesive member (e.g., the first adhesive member (P1) of FIG. 6). Thus, heat generated from electronic components (e.g., processor (510), printed circuit board (520), and / or first battery (291)) placed on the second surface (212) of the first housing (210) may be transferred to the first heat dissipation sheet (610).

[0072] In one embodiment, the first heat dissipation sheet (610) may be formed with a thicker thickness than the second heat dissipation sheet (620). Accordingly, the first heat dissipation sheet (610) may have a higher heat capacity than the second heat dissipation sheet (620). Additionally, as the first heat dissipation sheet (610) is formed with a thicker thickness than the second heat dissipation sheet (620), heat generated from electronic components placed on the second surface (212) of the first housing (210) can be efficiently transferred to the second heat dissipation sheet (620). In one embodiment, the electronic device (200) may prevent or avoid an increase in thickness caused by the placement of the first heat dissipation sheet (610) as the first heat dissipation sheet (610) is accommodated within the recess (500) of the first housing (210).

[0073] In one embodiment, the second heat dissipation sheet (620) is formed with a larger area than the first heat dissipation sheet (610) so as to diffuse heat transferred from electronic components placed on the second surface (212) of the first housing (210) through the first heat dissipation sheet (610) to the surroundings. For example, the second heat dissipation sheet (620) can disperse heat generated from electronic components over a larger area than the first heat dissipation sheet (610).

[0074] In one embodiment, referring to FIG. 5b, the second heat dissipation sheet (620) may be placed on the first surface (211) of the first housing (210) to cover at least a portion of the first heat dissipation sheet (610). For example, the second heat dissipation sheet (620) may be placed on the first surface (211) of the first housing (210) to cover at least a portion of the first heat dissipation sheet (610) by being placed between the flexible display (230) and the first surface (211) of the first housing (210). In one embodiment, one side of the second heat dissipation sheet (620) may be adhered to the first surface (211) of the first housing (210), and the other side opposite to the one side may be in contact with the flexible display (230). For example, the second heat dissipation sheet (620) may come into contact with the functional layer (460) of the flexible display (230) (e.g., the digitizer (461) and / or reinforcing plate (462) of FIG. 4). Thus, heat generated from electronic components (e.g., processor (510), printed circuit board (520), and / or first battery (291)) placed on the second surface (212) of the first housing (210) may be conducted to the second surface (212) of the first housing (210) - first surface (211) - first heat dissipation sheet (610) - second heat dissipation sheet (620) and diffused into the surroundings.

[0075] According to one embodiment, as illustrated in FIGS. 5a and 5b, at least one cushion layer (640) may be disposed on the first surface (211) of the first housing (210) at a position corresponding to the second camera module (216b) disposed on the second surface (212) of the first housing (210). In one embodiment, the cushion layer (640) may be disposed in an area (A2) corresponding to the second camera module (216b) on the first surface (211). The area (A2) corresponding to the second camera module (216b) may be a part of the first surface (211) of the first housing (210) corresponding to the area where the second camera module (216b) is disposed on the second surface (212) of the first housing (210). In one embodiment, the cushion layer (640) can cushion the external impact when an external impact is applied to an area corresponding to the second camera module (216b) in the flexible display (230), thereby preventing or avoiding damage to the flexible display (230) and the second camera module (216b).

[0076] In one embodiment, the cushion layer (640) may be formed from a cushioning material for cushioning action. For example, the cushion layer (640) may include silicone rubber, EVA (ethylene vinyl acetate), thermoplastic elastomer (TPE), polyimide (PI), nanofoam materials and / or polyurethane.

[0077] According to one embodiment, the cushion layer (640) may be composed of a plurality of layers. In one embodiment, when a step is formed on the surface of the area (A2) corresponding to the second camera module (216b) on the first surface (211) of the first housing (210), the cushion layer (640) may be composed of a plurality of layers and placed on the first surface (211) of the first housing (210) to fill the step of the first housing (210).

[0078] In one embodiment, the cushion layer (640) may include a first cushion layer (6401) and a second cushion layer (6402). In one embodiment, the first cushion layer (6401) may be placed on a first seating surface (not shown) formed on a first surface (211) of the first housing (210). The second cushion layer (6402) may be placed on a second seating surface (not shown) formed on the first surface (211) of the first housing (210). In one embodiment, the first seating surface may be positioned below the second seating surface when viewed from the side of the electronic device (200) (e.g., the first side member (213)) (e.g., when viewed in the -X direction of FIG. 5a), thereby forming a step with the second seating surface. The first cushion layer (6401) is formed to be thicker than the second cushion layer (6402) by the step difference and can form a substantially flat plane with the second cushion layer (6402). In some embodiments, the second mounting surface may be located below the first mounting surface when viewed from the side of the electronic device (200) to form a step difference with the first mounting surface. The second cushion layer (6402) is formed to be thicker than the first cushion layer (6401) by the step difference and can form a substantially flat plane with the first cushion layer (6401).

[0079] According to one embodiment, as illustrated in FIG. 5b, the cushion layer (640) may not overlap with the first heat dissipation sheet (610) when the electronic device (200) is viewed in a direction perpendicular to the flexible display (230) (e.g., the Z-axis direction in FIG. 5b). In one embodiment, the electronic device (200) may prevent or avoid an increase in thickness caused by the placement of the first heat dissipation sheet (610) between the flexible display (230) and the first housing (210) by positioning the first heat dissipation sheet (610) so that it does not overlap with the cushion layer (640). In some embodiments, at least a portion of the first heat dissipation sheet (610) may overlap with the cushion layer (640).

[0080] In one embodiment, referring to FIG. 5b, the second heat dissipation sheet (620) may overlap with the cushion layer (640) by being positioned so that at least a portion of it covers the cushion layer (640) when the electronic device (200) is viewed in a direction perpendicular to the flexible display (230) (e.g., the Z-axis direction of FIG. 5b). In some embodiments, the second heat dissipation sheet (620) may not overlap with the cushion layer (640). In one embodiment, whether the first heat dissipation sheet (610), the second heat dissipation sheet (620), and the cushion layer (640) overlap may vary depending on the placement area of ​​the electronic components placed inside the first housing (210).

[0081] In one embodiment, referring to FIG. 6, a first heat dissipation sheet (610), a second heat dissipation sheet (620), a cushion layer (640), and a cover sheet (630) may be disposed on the first surface (211) of the first housing (210). In one embodiment, the cover sheet (630) may be disposed between the flexible display (230) and the second heat dissipation sheet (620) to cover at least a portion of the first heat dissipation sheet (610), the second heat dissipation sheet (620), and / or the cushion layer (640). For example, the cover sheet (630) may be formed with a larger area than the first heat dissipation sheet (610) and the second heat dissipation sheet (620) to cover at least a portion of the first heat dissipation sheet (610), the second heat dissipation sheet (620), and the cushion layer (640). In one embodiment, the cover sheet (630) may be formed to have a certain level of heat resistance and / or thermal conductivity by including polyimide (PI), PET (polyethylene terephthalate), and / or ceramic.

[0082] In one embodiment, referring to FIG. 6, a first heat dissipation sheet (610) may be attached within a recess (500) formed on the first surface (211) of the first housing (210) through a first adhesive (P1). A second heat dissipation sheet (620) may be attached to the first heat dissipation sheet (610) through a second adhesive (P2). In one embodiment, the second heat dissipation sheet (620) may be attached to the first surface (211) of the first housing (210) through a third adhesive (P3), with the remaining area excluding the area covering the first heat dissipation sheet (610). In one embodiment, a cushion layer (640) (e.g., a first cushion layer (6401) and a second cushion layer (6402)) may be attached to the first surface (211) of the first housing (210) through a fourth adhesive (P4). The second heat dissipation sheet (620) can cover the cushion layer (640) by being attached to the cushion layer (640) in at least a portion through the fifth adhesive (P5) attached to the cushion layer (640). The cover sheet (630) can be attached to the first surface (211) of the first housing (210) through the fourth adhesive (P4) to cover at least a portion of the first cover sheet (610), the second cover sheet (620), and the cushion layer (640). In one embodiment, the cover sheet (630) can cover the cushion layer (640) by being attached to the cushion layer (640) in at least a portion through the fifth adhesive (P5).

[0083] According to one embodiment, as illustrated in FIG. 7, a waterproof member (700) (e.g., the first waterproof member (WP1) of FIG. 3) forming a waterproof space (701) may be disposed between the flexible display (230) and the first surface (211) of the first housing (210). In one embodiment, the first heat dissipation sheet (610), the second heat dissipation sheet (620), and the cushion layer (640) may be accommodated within the waterproof space (701) of the waterproof member (700). Thus, the first heat dissipation sheet (610), the second heat dissipation sheet (620), and the cushion layer (640) may be protected from external moisture and / or foreign substances through the waterproof member (700).

[0084] According to one embodiment, as illustrated in FIG. 8, the electronic device (200) comprises a flexible display (230), a second heat dissipation sheet (620), a first heat dissipation sheet (610), a first housing (210), a processor (510), a printed circuit board (520), and a first rear cover (240) (e.g., the first rear cover (240) of FIG. 1b may be laminated). In one embodiment, the processor (510) and / or the first battery (291) may be adjacent to or at least partially in contact with the second surface (212) of the first housing (210). Heat generated from electronic components placed on the second surface (212) of the first housing (210) (e.g., electronic components placed on the processor (510), the first battery (291), and the printed circuit board (520)) passes through the first housing (210) to the first of the first housing (210). The heat can be transferred to the first heat dissipation sheet (610) placed on the surface (211). As the first heat dissipation sheet (610) is accommodated within the recess (500) of the electronic device (200), an increase in the thickness of the electronic device (200) due to the placement of the first heat dissipation sheet (610) can be prevented or avoided. Meanwhile, the heat transferred to the first heat dissipation sheet (610) can be transferred to the second heat dissipation sheet (620) so that the heat can spread to the surroundings of the electronic components that are the heat source. Therefore, as the heat generated from the electronic components spreads to the surroundings, the temperature of the electronic components decreases, and the performance reduction of the electronic device (200) due to heat generation can be improved.

[0085] The above description is based on the premise that the first heat dissipation sheet (610), the second heat dissipation sheet (620), the cover sheet (630), and the cushion layer (640) are placed in the first housing (210), but it is not limited thereto. In one embodiment, the first heat dissipation sheet (610), the second heat dissipation sheet (620), the cover sheet (630), and the cushion layer (640) may be placed in the second housing (220). In some embodiments, the first heat dissipation sheet (610), the second heat dissipation sheet (620), the cover sheet (630), and the cushion layer (640) may be placed in a bar-type electronic device, rather than a foldable electronic device such as the electronic device (200), to dissipate heat generated from electronic components.

[0086] A foldable electronic device (200) may include a hinge device (400, 400-1) (e.g., a hinge assembly, a hinge structure, or a hinge module) and a first housing (210) and a second housing (220) that are foldably connected to each other in opposite directions through the hinge device. The electronic device (200) (e.g., a foldable electronic device) may operate in an in-folding and / or out-folding manner by rotating the first housing (210) with respect to the second housing (220) through the hinge device in a range of 0 to 360 degrees. The electronic device (200) may include a flexible display (230) positioned to be at least partially supported through a first housing (210) and a second housing (220) in an unfolded state. This flexible display (230) may include a plurality of layers (e.g., a transparent window layer (410), a POL (420), a polymer layer (440), or at least one functional layer (460)) positioned on the upper surface and / or lower surface relative to the display panel (430).

[0087] In one embodiment, the electronic device (200) may include a heat dissipation member for dissipating heat generated from electronic components to the surroundings. For example, the electronic device (200) may include a heat dissipation member such as a heat dissipation sheet (e.g., a heat dissipation plate) and a vapor chamber comprising graphite and / or a metal material. In one embodiment, the electronic device (200) may have a stacked structure in the order of a flexible display (230) - a heat dissipation sheet comprising graphite and / or a metal material - a first housing (210) - a vapor chamber - a processor (510).

[0088] Meanwhile, if the thickness of the electronic device (200) is reduced to improve the aesthetics and user convenience of the electronic device (200), the space for placing a heat dissipation member inside the electronic device (200) may be reduced. In this case, a sealed space, such as a vapor chamber, may be formed inside the electronic device (200), and space for placing a thick heat dissipation member may not be secured. In particular, if the thickness of the electronic device (200) is reduced, space for placing a heat dissipation member between the first housing (210) and the processor (510) may not be formed. Therefore, a new heat dissipation structure may be required to reduce the thickness of the electronic device (200).

[0089] The technical tasks intended to be accomplished in this document are not limited to those mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art to which this document belongs from the description below.

[0090] According to one embodiment of the present disclosure, an electronic device (200) may include a housing (210) comprising a first surface (211) and a second surface (212) opposite to the first surface. The electronic device may include a display (230) disposed on the first surface of the housing. The electronic device may include a camera module (216b) disposed on the second surface of the housing. The electronic device may include a processor (510) disposed on the second surface of the housing. The electronic device may include a battery (291) disposed on the second surface of the housing. The electronic device may include at least one cushion layer (640) disposed on the first surface of the housing and disposed in an area (A2) corresponding to the area where the camera module is disposed.

[0096] In one embodiment, the electronic device may further include a cover sheet (630) that covers the first heat dissipation sheet, the second heat dissipation sheet, and the cushion layer, which is disposed on the first surface of the housing.

[0097] In one embodiment, the display may include a display panel (430) and a functional layer (460) disposed on the back surface of the display panel and comprising a metal material. In one embodiment, the second heat dissipation sheet may be in contact with the functional layer.

The first cushion layer may be formed thicker than the second cushion layer by the amount of the step and may form a plane with respect to the second cushion layer.

[0099] In one embodiment, the housing may include a first housing (210) and a second housing (220) rotatably connected to the first housing through a hinge device (400, 400-1). In one embodiment, the display may include a bending region disposed in the first housing and the second housing, wherein at least a portion is deformed based on the rotational movement of the second housing relative to the first housing. In one embodiment, the first heat dissipation sheet, the second heat dissipation sheet, the camera module, the processor, the battery, and the cushion layer may be disposed in either the first housing or the second housing.

[0100] In one embodiment, the first heat dissipation sheet and the second heat dissipation sheet may include graphite and / or metal materials.

[0101] According to one embodiment of the present disclosure, an electronic device (200) may include a first housing (210) comprising a first surface (211) and a second surface (212) opposite to the first surface. In one embodiment, the electronic device may include a second housing (220) comprising a third surface (221) and a fourth surface (222) opposite to the third surface. In one embodiment, the electronic device may include a hinge device (400, 400-1) that rotatably connects the first housing and the second housing. In one embodiment, the electronic device may include a flexible display (230) supported through the first surface of the first housing and the third surface of the second housing. In one embodiment, the electronic device may include a camera module (216b) disposed on the second surface of the first housing. In one embodiment, the electronic device may include a processor (510) disposed on the second surface of the first housing. In one embodiment, the electronic device may include a battery (291) disposed on a second surface of the first housing. In one embodiment, the electronic device may include at least one cushion layer (640) disposed on a first surface of the first housing and in an area (A2) corresponding to the area where the camera module is disposed. In one embodiment, the electronic device may include a first heat dissipation sheet (610) disposed on a first surface of the first housing, at least a portion of which overlaps with the processor and the battery when viewed vertically from the flexible display, and does not overlap with the cushion layer. In one embodiment, the electronic device may include a second heat dissipation sheet (620) disposed between the flexible display and the first heat dissipation sheet, at least a portion of which overlaps with the processor, the battery, and the cushion layer when viewed vertically from the flexible display.

[0102] In one embodiment, the first housing may include a recess (500) that forms a step with respect to the first surface. The first heat dissipation sheet may be received in the recess and adhered to the first surface of the first housing.

[0103] In one embodiment, the recess may be formed with a size corresponding to the first heat dissipation sheet.

[0104] In one embodiment, the second heat dissipation sheet may be formed with a larger area than the first heat dissipation sheet when viewed from a direction perpendicular to the flexible display and looking at the first housing.

[0105] In one embodiment, the electronic device may further include a waterproof member (700) disposed between the flexible display and the first surface of the first housing and forming a waterproof space (701). The first heat dissipation sheet, the second heat dissipation sheet, and the cushion layer may be accommodated in the waterproof space.

[0106] In one embodiment, the thickness of the first heat dissipation sheet may be thicker than the thickness of the second heat dissipation sheet.

[0107] In one embodiment, the electronic device may further include a cover sheet (630) that covers the first heat dissipation sheet, the second heat dissipation sheet, and the cushion layer, which is disposed on the first surface of the first housing.

[0108] In one embodiment, the flexible display may include a display panel (430) and a functional layer (460) disposed on the back surface of the display panel and comprising a metal material. In one embodiment, the second heat dissipation sheet may be in contact with the functional layer.

[0109] In one embodiment, the cushion layer may include a first cushion layer (6401) disposed on a first seating surface formed on a first surface of the first housing and a second cushion layer (6402) disposed on a second seating surface formed on a first surface of the first housing. When viewed from the side of the electronic device, the first seating surface may be positioned below the second seating surface to form a step with respect to the second seating surface. The first cushion layer may be formed thicker than the second cushion layer by the amount of the step and may form a plane with respect to the second cushion layer.

[0110] According to various embodiments disclosed in this document, a plurality of heat dissipation sheets (610, 620) may be disposed between a flexible display (230) and a first housing (210). The plurality of heat dissipation sheets (610, 620) may be thin film plates comprising graphite and / or a metal material (e.g., aluminum, copper, iron). Thus, the thickness may be relatively thin compared to a heat dissipation member in which a space is formed inside, such as a vapor chamber. In this disclosure, a plurality of heat dissipation sheets (610, 620) may be disposed in an area corresponding to an electronic component that is a heat source. As the plurality of heat dissipation sheets (610, 620) are disposed in an overlapping manner, heat dissipation performance and thermal capacity may be improved compared to an embodiment in which a single heat dissipation sheet is disposed. Accordingly, when the space for placing a heat dissipation member is reduced as the thickness of the electronic device (200) is reduced, heat generated from the electronic component can be diffused to the surroundings by placing a thin film heat dissipation sheet (610, 620) between the flexible display (230) and the first housing (210).

[0111] Additionally, a rear camera module (e.g., the second camera module (216b) of FIG. 1b) may be disposed on the rear of the first housing (210). A cushion layer (640) may be disposed on the front of the first housing (210) in an area corresponding to the rear camera module. The cushion layer (640) can cushion the external impact when an external impact is applied to the area corresponding to the rear camera module in the flexible display (230), thereby preventing or avoiding damage to the flexible display (230) and the rear camera module.

[0112] In addition, various effects that can be identified directly or indirectly through this document may be provided.
