Abstract

In order to improve a heat pipe comprising a housing containing a heat-transporting medium, this housing having an evaporation region and a condensation region, such that the heat pipe operates in an optimum manner with respect to its transfer capacity, it is suggested that a vapor channel be provided in the housing, that an unwettable porous structure be arranged between the vapor channel and the condensation region, this structure being impermeable for the condensate due to its pore size, and that a condensate channel be provided for guiding the condensate from the condensation region to the evaporation region.
