摘要:
A heat pipe is provided for cooling an electronic component of a printed circuit board. The heat pipe includes a tube having an inner diameter surface defining a bore, with the tube having first and second ends along the bore. The heat pipe further includes a sorbent material coated onto the inner diameter surface of the tube, a first liquid contained within the bore, and a second liquid adsorbed by the sorbent material. The second liquid has a second boiling temperature that is higher than a first boiling temperature of the first liquid. The first liquid vaporizes into a first vapor, in response to the tube receiving heat from the electronic component and the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material and vaporizes into a second vapor in response to the second liquid reaching the second boiling temperature.
