Refrigerating heat pipes

The concept of novel heat pipe application, called refrigerating heat pipes (RHPs) is discussed. Thermodynamic classification of the RHPs is proposed. The possibilities of using classical driving forces for the RHP analysis (osmotic, inertial, capillary, gravitational, electrohydrodynamical, etc.) are firmly established. The cycles of absorption, vapour-ejector and mixed RHP with respect to their thermodynamic performance are considered.
