The invention relates to a heat exchanging device (100, 200, 400), to a heat pump, to a domestic appliance, and to a method of operating a heat exchanging device (100, 200, 400). A first hollow profile (110, 210, 410) is configured to conduct a first medium. A second hollow profile (120, 220, 420) is configured to conduct a second medium. At least a part of the second hollow profile (120, 220, 420) is wound around at least a part of the first hollow profile (110, 210, 410). A nominal width (w) of the second hollow profile (120, 220, 420) is smaller than a nominal width of the first hollow profile (110, 210, 410). An outer surface of the first hollow profile (110, 210, 410) comprises a first contact portion, an outer surface of the second hollow profile (120, 220, 420) comprises a second contact portion, and the first contact portion and the second contact portion are coupled by means of a soldered connection. |
