Metal and carbon laminate transmitting electromagnetic waves or having function of heat radiation

Abstract

Disclosed herein is a metal and carbon laminate transmitting electromagnetic waves or having a function of heat radiation including a first layer configured of a carbon material, and a second layer configured of metal, wherein a groove is formed on at least one area of the second layer in order to allow the first layer to be exposed, thereby giving a characteristic of electromagnetic wave transmission, or wherein a slit is formed on the first layer along with the groove. According to the above-described invention, the metal and carbon laminate transmitting electromagnetic waves or having a function of heat radiation may have an advantageous effect of being attached to an outer case of diverse devices that is configured of plastic, being equipped inside the device and, most particularly, being capable of enhancing the aesthetic external features of the device along with the heat radiation function by adding a metallic texture when applied to the outer case, and an advantageous effect ofbeing installed at any position within the device regardless of the moving direction of the electromagnetic waves, thereby enabling an optimal selection of an installation position for heat radiation.

Description

technical field [0001] The present invention relates to a metal and graphite laminate that can penetrate radio waves or have heat dissipation properties, and in particular provides a metal and graphite laminate that forms a groove with a specific width in a part of the metal layer. Exposed, or forming a slit in the graphite while forming a groove, and when the above-mentioned laminate is attached to the case of a device having a wireless charging or wireless communication function or built into the case thereof, even when it is usually equipped with radio waves Radio wave penetration can also be achieved in the presence of a metal layer with a shielding function, and because of its heat dissipation performance, it can prevent overheating of the applicable device and ensure its stable use state, so it can be used to replace the existing heat dissipation parts, that is, the carbon series A heat sink or a laminate of metal and graphite that can penetrate radio waves or have heat ...

AI Technical Summary

Problems solved by technology

[0007] However, when it is necessary to apply the metal body heat sink to devices that require radio wave penetration characteristics such as wireless chargers, mobile phones, and NFC, it cannot be applied to the above devices because of its own radio wave shielding properties. Install heat sinks where the electric waves propagate, so only graphite heat sinks can be used in the cases described above
