1. A method of measuring a heat transfer coefficient, comprising the steps of:

  • exposing a surface having a temperature to an environment having a different temperature and in which heat transfer takes place between the exposed surface and the environment by at least one of condensation, convection, and radiation mechanisms, the exposed surface having a predetermined area;

    transporting heat transferred to the exposed surface to a location external to said environment by passage of a working fluid having a heat content along a heat pipe;

    measuring the heat content of the working fluid at said external location;

    determining a temperature difference between the temperature of the exposed surface and the temperature of the environment; and

    determining the heat transfer coefficient from said heat content, said temperature difference and said predetermined area.
