Benefits of technology

The inventive technology described by this patented product helps improve cooling efficiency when used on electronic devices due to its ability to conduct away excess thermal energy from certain parts inside them while still allowing some part outside their body (the case being cooled). This means less airflow into these areas during cold weather conditions or even if they are very hot at all times.

Problems solved by technology

This technical problem addressed by our researchers relates to improving cooling efficiency for electronics due to their complexity and increased power consumption caused by generating large amounts of heat. Existing methods like adding an artificial graphit sheet on top may result in poorer airflow over certain areas where excessive temperatures occur compared to others. To address these issues, some current solutions involve incorporating multiple layers of artificial graphs into one component instead of just having them all together. However, such approaches often require expensive manufacturing processes involving vacuum deposition techniques.

Abstract

The invention discloses a composite heat dissipation material. The composite heat dissipation material comprises a graphite combined layer which comprises two graphite layers, wherein two adjacent graphite layers are directly adhered together through an adhesion layer; a thermal penetrability degrading layer is arranged outside the graphite combined layer; and an adhesion layer is arranged betweenthe thermal penetrability degrading layer and the graphite combined layer. According to the composite heat dissipation material, the heat dissipation of a heat source is realized, the upward thermalpenetration time can be prolonged, more long horizontal heat conduction time of the composite heat dissipation material is realized, and the surface temperature of the composite heat dissipation material is decreased.
