Abstract

Evaporative heat exchange device comprising, as the evaporation structure, a wall of a heat conducting material including, on the face bathed in a liquid that partially evaporates upon contact, a network of local extensions constituted in such a way that they present, in operation, a substantial temperature gradient on their side faces, characterized in that the extensions have substantially contiguous bases, their section decreases by at least a substantial part of their height, going from their base to their end, their height b , measured perpendicular to the surface of the wall, is defined by the equation: ** (See formula) ** and its form is such that its surface sl exposed to the liquid to be evaporated is attached to its geometric base surface sa by the equation: ** (See formula) ** equations in which: o is the thermal conductivity of the material that constitutes the extensions, q the critical boiling flow of the liquid to evaporate under the operating conditions of the device, referred to the surface unit of the surface that heats the liquid, Θ the allowed temperature difference between the base and the end of the extensions, Φ the specific maximum heat flow specified for the wall, referred to the unit of surface area defined by the bases of the extensions, p a number without dimensions, comprised between 0.8 and 1.6, while the factors listed above are expressed in a coherent system of units, k a number between 1 and 2.
