Abstract
An evaporator for discharging waste heat, for example from a space craft, uses at least one working fluid that is changed from its liquid state to its vapor state. The evaporator has at least one, preferably several, evaporator elements forming a unit. Each element has a liquid space separated from a vapor space by a tubular capillary separation member. The vapor space is divided into primary channels extending in parallel to the separation member. Secondary channels are formed in wall surfaces of the vapor space facing the separation member. The primary and secondary channels communicate with each other and extend approximately perpendicularly to each other. The secondary channels have a cross-sectional flow area which is substantially smaller than the cross-sectional flow area of the primary channels.
