Abstract
A heat pipe with a non-condensable gas includes a thermal conductor, and a working fluid and a non-condensable gas filled into a hollow chamber of the thermal conductor, and the thermal conductor has a heat-absorbing side attached to a heat-generating electronic component and an exothermal side attached to a radiator, and the exothermal side has at least one protrusion, and the exothermal side with the protrusion can reduce the contact area with the radiator, and the heat pipe lowers the conduction efficiency by the non-condensable gas and the protrusion, so as to achieve a work efficiency of the heat-generating electronic component in an operation within a working temperature range.
