A heat pipe (20) includes a pipe (21), a wick (22), and an operating fluid. The wick is fixedly engaged with an inside wall of the pipe. The operating fluid is sealed in the pipe and soaks the wick. The operating fluid includes a pure liquid, and a plurality of carbon nanocapsules (23) suspended in
A heat pipe (20) includes a pipe (21), a wick (22), and an operating fluid. The wick is fixedly engaged with an inside wall of the pipe. The operating fluid is sealed in the pipe and soaks the wick. The operating fluid includes a pure liquid, and a plurality of carbon nanocapsules (23) suspended in the pure liquid. The pure liquid can be selected from the group consisting of pure water, ammonia, methanol, acetone and heptane. Each carbon nanocapsule is a polyhedral carbon cluster (231), with a metal (232) having high thermal conductivity filled therein. The operating fluid has high thermal conductivity and uniform operation, and is recyclable with no pollution of the environment. The heat pipe has correspondingly high thermal conductivity.

What is claimed is: 1. A heat pipe comprising: a pipe; a wick engaged with an inside wall of the pipe; and an operating fluid sealed in the pipe and soaking the wick; wherein the operating fluid comprises a liquid and a plurality of carbon nanocapsules suspended in the liquid, and each of the carbon nanocapsules has a metal with high thermal conductivity received therein. 2. The heat pipe as claimed in claim 1, wherein the metal is selected from the group consisting of copper, aluminum, gold, silver, and any alloy thereof. 3. The heat pipe as claimed in claim 1, wherein the liquid is selected from the group consisting of pure water, ammonia, methanol, acetone, and heptane. 4. The heat pipe as claimed in claim 1, wherein a mass of the carbon nanocapsules is in the range from one percent to three percent of that of the operating fluid. 5. The heat pipe as claimed in claim 1, wherein a diameter of each of the carbon nanocapsules is in the range from 2 to 60 nanometers. 6. The heat pipe as claimed in claim 1, wherein the carbon nanocapsules are made by an arc discharge method. 7. The heat pipe as claimed in claim 1, wherein a material of the pipe is selected from the group consisting of copper, aluminum, steel, carbonic steel, stainless steel, iron, nickel, titanium, and any alloy thereof. 8. The heat pipe as claimed in claim 1, wherein a cross-section of the pipe is circular, elliptical, square, rectangular, oblong, or rippled. 9.

The heat pipe as claimed in claim 6, wherein in the arc discharge method, a mixture of graphite and either of copper or aluminum is used as a cathode. 12. A heat pipe comprising: a pipe; and an operating fluid sealed in the pipe; wherein the operating fluid comprises a liquid and a plurality of carbon nanocapsules suspended in the liquid, and each of the carbon nanocapsules has a metal with high thermal conductivity received therein. 13. The heat pipe as claimed in claim 12, wherein the metal is selected from the group consisting of copper, aluminum, gold, silver, and any alloy thereof. 14. The heat pipe as claimed in claim 12, wherein the liquid is selected from the group consisting of pure water, ammonia, methanol, acetone, and heptane. 15. The heat pipe as claimed in claim 12, wherein a mass of the carbon nanocapsules is in the range from one percent to three percent of that of the operating fluid. 16. The heat pipe as claimed in claim 12, wherein a diameter of each of the carbon nanocapsules is in the range from 2 to 60 nanometers. 17. The heat pipe as claimed in claim 12, wherein a material of the pipe is selected from the group consisting of copper, aluminum, steel, carbonic steel, stainless steel, iron, nickel, titanium, and any alloy thereof. 18. The heat pipe as claimed in claim 12, wherein a cross-section of the pipe is circular, elliptical, square, rectangular, oblong, or rippled. 19. The heat pipe as claimed in claim 18, wherein a width of the pipe is in the range from 2 to 200 micrometers. 20. The heat pipe claimed in claim 12, further comprising a wick engaged with an inside wall of the pipe.
