Description
Electronic device including a heat transfer member
[0001] The various embodiments disclosed in this document relate to electronic devices including heat transfer members.
[0002] While electronic devices are becoming increasingly smaller, their functions are becoming increasingly diverse. As electronic devices become smaller and slimmer, electrical components embedded within them may be positioned so that the gap between them and surrounding structures becomes increasingly narrow or concentrated, and they may generate high temperatures due to the performance of various functions. Such high temperatures can cause malfunctions in electronic devices and cause discomfort to users. Therefore, electronic devices may require a heat transfer structure capable of effectively transferring heat generated from electrical components to the surroundings.
[0003] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.
[0004] The electronic device may include at least one substrate (e.g., a printed circuit board (PCB)) disposed in an internal space and a plurality of electrical components (e.g., an application processor) as a heat source disposed on the substrate. Heat generated from the plurality of electrical components may be transferred to a heat dissipation structure (e.g., a vapor chamber) through a thermal interface material (TIM) in contact with at least some of the plurality of electrical components, and may diffuse into the surroundings.
[0005] However, since the heat transfer member is positioned to make contact primarily with the electrical component that generates the most heat among multiple electrical components, heat generated from other surrounding electrical components may not be effectively diffused. Furthermore, if the heat transfer member is designed considering all electrical components placed on the substrate, it includes a complex structure corresponding to the respective positions and shapes of the multiple electrical components; consequently, the manufacturing cost of the heat transfer member increases, and the yield may decrease during mass production.
[0006] Various embodiments of the present disclosure may provide an electronic device comprising a heat transfer member having an improved heat dissipation structure.
[0007] According to various embodiments, an electronic device including a heat transfer member that can help improve the heat transfer performance of a plurality of electrical elements can be provided.

[0012] A method for manufacturing a heat transfer member according to various embodiments of the present disclosure may include a first step of heating a mold having a shape corresponding to the first heat transfer member, which is divided into at least two regions to cover at least some of the electrical elements among a plurality of electrical elements disposed on a printed circuit board; a second step of applying the heated mold to a base material of the first heat transfer member formed of a flexible material; and a third step of punching out the outer edge of the deformed first heat transfer member.
[0013] Since the electronic device according to exemplary embodiments of the present disclosure includes a first heat transfer member formed based on the height, heat generation level, and / or density of at least one electric element included in a plurality of electric elements, the heat transfer performance of the electronic device can be improved, the impact applied to the plurality of electric elements can be mitigated, the yield can be increased, and the manufacturing cost can be reduced.

For example, the first electric elements (310) covered by the first region (510) may have a first height range (e.g., a first-1 height range (t1-1), a first-2 height range (not shown), and a first-3 height range (not shown)), and the second electric elements (320) covered by the second region (520) separated from the first region (510) may have a second height range (t2) different from the first height range. In one embodiment, the regions (510, 520, 530, 540, 551, 552, 553, 554, 555, 556, 557, 558) of the first heat transfer member (500) may be separated in such a way that they have different depths and / or heights from the outer surface of the first heat transfer member (500).For example, regions (510, 520, 530, 540, 551, 552, 553, 554, 555, 556, 557, 558) of the first heat transfer member (500) may be distinguished by recesses formed lower than the outer surface and / or protrusions formed higher than the outer surface.
[0061] According to various embodiments, a plurality of electrical elements (300) may be arranged to be covered by a first heat transfer member (500).

In this case, the highest electric element among the plurality of 5-6 electric elements (356) may be in contact with the 5-6 region (556), but the remaining electric elements among the plurality of 5-6 electric elements (356) may not be in contact with the 5-6 region (556). In one embodiment, the first region (510) and the second region (520) may be distinguished based on the height of at least one electric element (e.g., first memory (311) and processor (312)) included in the first electric elements (310) and / or the height of at least one electric element (e.g., DC circuit (321)) included in the second electric elements (320).
