Investigation of heat transfer by evaporation in capillary grooves with a porous coating

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The results of experimental investigations of heat pipe evaporators with axial grooves of various profiles are presented. A method for enhancing heat transfer by liquid evaporation from capillary grooves of evaporators is proposed. It is realized by applying to the capillary groove surface a thin (25–100 μm) porous coating containing pores up to nanosize. The use of such a coating has made it possible to increase the heat transfer coefficients by evaporation by a factor of 1.5–2.
