Cov Nanotubes, zoo li graphite thiab pob zeb diamond, yog cov cua sov zoo heev. Zoo li lawv cov hluav taws xob ua haujlwm, carbon nanotubes tseem muaj axial thermal zoo thiab yog qhov zoo tshaj plaws thermal cov ntaub ntawv. Theoretical suav qhia tias cov pa roj carbon monoxide (cov pa xaim) The researchers measured that the room temperature thermal conductivity of single-walled carbon nanotube（SWCNT） is close to 3500W/m•K, which is much greater than that of diamond and graphite (~2000W/m•K). Txawm hais tias lub tshav kub sib pauv kev ua tau zoo ntawm cov pa roj carbon nanotubes nyob rau hauv cov kev taw qhia tsawg, thiab cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide, thiab lawv cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide, thiab lawv cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide)

Qhov zoo tshaj thermal conductivity ntawm ib leeg-walled carbon nanotubes (swcnts) yog ua rau lawv lub tshuab cua sov ntawm cov computer radiators yav tom ntej. Cov pa roj carbon nanotube cpu radiator, uas yog cov ua los ntawm cov pa roj carbon nanotubes, muaj lub thermal conductivity 5 zaug uas feem ntau siv tooj liab cov ntaub ntawv. Nyob rau tib lub sijhawm, ib leeg-walled carbon firbon nanotubes muaj cov ntawv thov zoo sib xyaw thiab siv tau rau ntau cov khoom kub xws li tshuab thiab Rockets.
