Heat exchanger with a phase change material and method for its manufacture

Heat storage device comprises a housing (10), in which a phase change material and a heat conducting structure surrounded by the phase change material (14) are arranged. The heat conducting structure exhibits a space grid-a (16) made of bars of same material extending to the junction of the space grid. An independent claim is also included for producing a heat storage device comprising: (i) supplying a powdery active material to be produced on the heat conducting structure; (ii) fusing defined regions of the powdery active material by thermal effect of an energetic beam; (iii) repeating the steps (i) and (ii) until the fused regions of a spatial grid-a made of bars of same material extending to the junction of the space grid-a is formed; (iv) removing the non-fused powdery active material; and (v) introducing the phase change material, so it surrounds the heat conducting structure.
