Description

technical field [0001] The invention relates to a heat conduction device, in particular to a heat conduction device that can be independently fixed and can be easily mounted with high density. Background technique [0002] Recently, the amount of heat generated by the high integration and performance of heat-generating electronic components or modules is increasing. In addition, as product miniaturization progresses, heat generation density increases, and heat dissipation methods are becoming more important. [0003] This situation is more obvious in mobile terminals such as smart phones or tablet computers, and the generated heat needs to be cooled directly or transferred to other places for cooling. [0004] As the heat transfer device, a heat transfer plate or a graphite plate with good thermal conductivity in the horizontal direction can be used, but if the heat transfer is not sufficient, a heat transfer pipe, a heat sink or a soaking plate (hereinafter referred to as ...

AI Technical Summary

Problems solved by technology

[0008] Therefore, when the shape of the heat pipe is curved or the like is complicated and the length is long, it is necessary to prepare the shape of the double-sided adhesive tape accordingly. It is difficult to prepare and install the tank in a matching way

[0009] Also, in order to fix the heat pipe, an additional double-sided adhesive tape is required, so it has the disadvantage of being inconvenient for high-density mounting and requiring additional setup costs

[0010] Moreover, since the heat pipe is made of metal, it cannot elastically thermally contact the heat source or the metal shell for cooling, so that it cannot conduct heat quickly and reliably.

[0011] Therefore, it is usually necessary to additionally interpose thermally conductive components such as thermal pads (Thermal Pad), thermal grease (Thermal Grease) or heat dissipation space fillers (Thermal Gap Filler) between the heat pipe and the heat source, or between the cooling shell. Shortcomings

[0012] In particular, in the case where a heat pipe made of metal is combined and in contact with a plurality of metal fins for cooling, there is a disadvantage that the heat conduction effect is not good due to direct contact between metal and metal
