▎ 摘　　要

NOVELTY - A thermal interface material (100) is made of a first graphene sheet (1), a second graphene sheet (2), and an array of carbon nanotubes (3). The array of carbon nanotubes is formed between the graphene sheets. The first end of each carbon nanotube of the array is covalently bonded via carbon-carbon bonds to the first graphene sheet and/or second end of each carbon nanotube of the array is covalently bonded via carbon-carbon bonds to the second graphene sheet. A circulating fluid is in fluid communication with the array of carbon nanotubes. USE - Thermal interface element of heat exchange system (claimed) for cooling hot spots on chip. ADVANTAGE - The high efficient exchange of heat with a surface is attained rapidly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) heat exchange system; (2) use of thermal interface element; and (3) method for cooling a surface. DESCRIPTION OF DRAWING(S) - The drawing shows the explanatory view of the thermal interface element. Graphene sheets (1,2) Array of carbon nanotube (3) Holes (11,12) Thermal interface material (100)
