Abstract

The subject of the invention relates to a phase-change heat exchanger comprising a plate (1) of the exchanger, a set of pipes (10) through which the working medium flows, heating elements (5) arranged directly below the plate (1) of the exchanger or integrated into it, and a hydraulic system with a control unit (8), wherein the plate (1) of the heat exchanger with the pipe system (10) and heating elements (5) is immersed in a tank (Z) filled with a liquid phase-change medium, preferably water, characterized in that the plate (1) of the heat exchanger is positioned near the bottom of the tank (Z) filled with phase-change medium, preferably horizontally, such that above the plate (1) of the exchanger, there is a column of phase-change medium, preferably water, and the plate (1) is equipped with a number of protrusions (4), arranged next to each other in parallel rows across the entire surface of the plate (1), wherein these protrusions (4) are in the form of elongated rectangular prisms with a base chosen from: a polygon or a figure formed from segments of curves, including figures formed from segments of ellipses, and side walls (2) that converge at an angle at the apex part of the protrusion (4), wherein the apex part is in the form of an apex (4') in which the side walls (2) converge at an angle α ranging from 30° to 120°, preferably between 45° and 90°, in a shape chosen from: an apex with a sharp-edged tip, a truncated apex, or an apex equipped with a convex socket part (12) running along the apex section of the protrusion (4).
