Claim of US Patent No. 10,015,910

1. A heat pipe, comprising:a housing comprising a first end to couple to a processing unit and a second end to couple to a heat sink, wherein the housing has an outer surface and an inner surface, the inner surface defines a cavity in the heat pipe;
a wick structure coupled to the inner surface; and
a binary working fluid in the cavity comprising a composition of isopropanol and water, the boiling point as a function of the composition of the isopropanol and the water is within one degree Celsius of and less than an azeotropic boiling point in a thermodynamic phase diagram as a function of a temperature and the composition of the isopropanol and the water.
