Abstract (en)

[origin: WO9942781A1] The invention relates to a heat exchanger (10) based on heat energy bound to working fluid in phase transition comprising heat exchanger elements (12) that contain working fluid for conducting elsewhere the heat energy generated by a heat source (11). The heat exchanger (10) of the invention comprises an initially one-piece heat exchanger part (13) formed in such a manner that two initially separate surface areas (13a, 13b) thereof are brought into the vicinity of one another so as to form at least one heat exchanger element (12) by the initially one-piece heat exchanger part (13). The heat exchanger (10) of the invention may preferably include heat exchanger members (17) intensifying the heat transfer capacity of the heat exchanger (10) of the invention. The invention also relates to a method for producing the heat exchanger (10) based on heat energy bound to working fluid in phase transition.
