Heat dissipation structure and heat dissipation system adopting the same

A heat dissipation system, comprising:

• a heat sink;
• a heat source;
• and
• a heat dissipation structure positioned between the heat sink and the heat source, the heat dissipation structure comprising a thermal interface material and a transition layer, the thermal interface material comprising a matrix and a plurality of carbon nanotubes dispersed in the matrix, the thermal interface material having a first surface and a second surface opposite to the first surface, and the transition layer being positioned on one of the first surface or the second surface of the thermal interface material, wherein a thickness of the transition layer is in a range from about 1 nanometer to about 100 nanometers;
• the transition layer contacts with the carbon nanotubes of the thermal interface material;
• an interface thermal resistance between the transition layer and the heat source or the heat sink is less than that between the plurality of carbon nanotubes and the heat source or the heat sink.
