Abstract
A heating system for supplying thermal energy to a heater of a machine such as a hot gas engine, this system using a heat-transporting medium which flows within a closed space between a heat-receiving portion to a heat-discharging portion. Thermal energy is supplied from a heat source through a wall in the heat-receiving portion with the transporting medium changing from the liquid phase to the-vapor phase, and the absorbed thermal energy is transferred to the heater in the heat-discharging portion by changing from the vapor phase into the liquid phase. The wall parts of the heat-receiving portion, through which thermal energy can be supplied from the heat source to the transporting medium, comprise on their surface contacting this medium of a layer of a porous material having a capillary structure whereby liquid-phase medium is distributed on said walls.
