Claim 13:
14. A heat exchanger for a heat pump, comprising
a chamber for a working fluid; and
a wall for heat exchange between the working fluid in the chamber and a substance in a space on the opposite side of the wall,
said chamber comprising a structure of a filling material that is substantially non-absorbent with respect to the working fluid,
said structure defining a plurality of channels for the working fluid, said channels at least being partly bound by the wall separating the chamber from the space,
said channels providing passage for the working fluid from an inlet of the chamber to an outlet of the chamber,
the heat exchanger further comprising a vessel for containing the working fluid, the vessel forming the chamber, wherein the chamber is bounded by a surface of a vessel wall and a wall of at least one tube, the vessel comprising an inlet and an outlet for transport of the working fluid into and out of the chamber;
said at least one tube forming the space for the substance, of which at least one tube portion is inside the vessel, wherein a first end of the tube portion is fixed to a first orifice of the vessel and a second end of the tube portion is fixed to a second orifice of the vessel to enable fluid communication into and/or out of the tube portion through the first orifice and the second orifice;
wherein the chamber outside said at least one tube is filled with the structure;
wherein the at least one tube portion has an outer surface in contact with the structure;
wherein the at least one tube portion is arranged in a plurality of windings around a wall portion of said vessel wall and around a region external to the chamber.
