1. A heat transfer device for conducting heat from a heat source, the heat transfer device comprising:

  • an evaporator for generating a vapor;

    a condenser in fluid communication with the evaporator, wherein the evaporator and the condenser together define an interior space of the heat transfer device; and

    a vapor flow restrictor interposed between the evaporator and the condenser,wherein the vapor flow restrictor has opposed surfaces with an orifice extending between the opposed surfaces, the orifice having an inlet and an outlet having cross-sectional areas of equal size with the inlet disposed in one of the opposed surfaces and the outlet disposed in the other surface of the opposed surfaces, wherein the orifice defines a vapor flow path from the evaporator to the condenser, wherein the vapor flow path is unobstructed through the orifice at all operating temperatures, andwherein the vapor flow restrictor and an interior surface of the heat transfer device define between them a liquid flow path for working fluid to pass in the interior space from the condenser back toward the evaporator.
