Title: EVAPORATOR AND/OR CONDENSER ELEMENT WITH SUPERFICIALLY EMBEDDED POROUS PARTICLES
Abstract:
The present invention relates to an evaporator and/or condenser element which has a substrate structure (1) composed of a thermally conductive material with a surface for the evaporation or sublimation or condensation or resublimation of a liquid or solid medium. Particles (2) composed of a porous material are embedded into the surface of the substrate structure (1) so as to partially project out of said surface. In this way, a reduction of the required evaporation superheating temperature, an increase of the volume-specific and mass-specific evaporation and condensation performance, and an increased volume-specific refrigerant storage capacity are achieved.
