Definitions

  • the disclosure relates to a heat exchanging device, to a heat pump, to a domestic appliance, to a method of operating a heat exchanging device, and to a method of providing a heat exchanging device.
  • DE2743333A1 discloses a heat recovery system recovering heat from waste water from washing basins, sinks, bidets and showers. These sanitary installations have hot and cold water supply and smell trap in outlet. Heat recovered is used for fresh water preheating.
  • the smell trap itself or a connected vessel forms heat exchanger with a helical hollow profile coil. Water from cold water supply flows through this helical coil and cold water is warmed by the waste water heat.
  • the preheated water flows into a hot water boiler or mixing valve.
  • the whole waste water vessel and heat exchanger can be built into a boiler tank.
  • a first medium e.g., wastewater
  • a hollow profile carrying the second medium e.g., fresh water
  • the material of the hollow profile carrying the second medium then has to be chosen appropriately, in order to avoid degradation from, e.g., corrosion.
  • a heat exchanging device comprising a first hollow profile configured to conduct a first medium; a second hollow profile configured to conduct a second medium, wherein at least a part of the second hollow profile is wound around at least a part of the first hollow profile; wherein a nominal width of the second hollow profile is smaller than a nominal width of the first hollow profile; wherein an outer surface of the first hollow profile comprises a first contact portion, wherein an outer surface of the second hollow profile comprises a second contact portion, and wherein the first contact portion and the second contact portion are coupled by means of a soldered connection.
  • hollow profile shall not be limited to a hollow cylinder for conducting fluids.
  • cross section of the first and second hollow profiles is not limited to a circular shape, but the term hollow profile shall include other hollow profiles suitable for conducting fluids as well.
  • the second medium may be, e.g., a refrigerant, or more generally a phase-changing, pure, non-polluted fluid.
  • the first medium is typically a fluid, more specifically a fluid carrying dirt particles, even more specifically wastewater. If the first medium is water, such as, e.g., wastewater, the material of the second hollow profile therefore does not have to be adapted to provide sufficient protection from corrosion.
  • the first contact portion and the second contact portion are coupled by means of a soldered connection. Consequently, by providing soldering connections between the first and second hollow profiles, the present invention achieves an improved thermal contact between first medium and second medium.
  • the outer surface of the second hollow profile comprises an outside portion arranged opposite to the second contact portion, wherein the outside portion and the second contact portion are parallel.
  • the present embodiment achieves the effect of maintaining a small nominal width of the second hollow profile.
  • a convex curving of the second hollow profile is avoided.
  • the present embodiment further improves on suppressing significant thermal differences along the cross section profile.
  • a cross section of the second hollow profile has a trapezoid shape, preferably a uniform trapezoid shape, where the second contact portion corresponds to a basis of the trapezoid shape.
  • the first hollow profile comprises a straight portion, wherein the second hollow profile is wound around at least a part of the straight portion.
  • a central axis of the part of the second hollow profile that is wound around the part of the first hollow profile corresponds to a helix having a uniform pitch. Choosing a uniform pitch is one possibility to have a uniform work piece. It further enables the manufacturer to prepare second hollow profiles of differing lengths without having to decide on the respective lengths during winding of a basic hollow profile work piece. In other words, it is possible to first prepare a wound hollow profile of a given standard length and to subsequently, depending on the desired respective lengths of second hollow profiles, cut the basic work piece into a number of second hollow profiles of desired lengths.
  • a distance between two adjacent windings of the second hollow profile is equal to or larger than 1.5 mm.
  • a distance between two adjacent windings of the second hollow profile is equal to or smaller than 0.3 mm.
  • the first hollow profile comprises stainless steel, wherein the first hollow profile preferably consists of stainless steel.
  • Stainless steel has superior properties in suppressing corrosion, rust or water stains.
  • the first medium conducted in the first hollow profile corresponds to water, specifically wastewater from a domestic appliance, such as a dishwasher or washing machine.
  • the second hollow profile comprises aluminum, wherein the second hollow profile preferably consists of aluminum. Due to its excellent thermal conductivity, aluminum is well-suited as a heat sink material.
  • the second medium conducted in the second hollow profile corresponds to a refrigerant, specifically, a refrigerant configured to regain the heat of wastewater in a domestic appliance, such as a dishwasher or washing machine.
  • the nominal width of the second hollow profile corresponds to a distance between a first inner surface section of the second hollow profile arranged opposite to the second contact portion and a second inner surface section of the second hollow profile arranged opposite to the outside portion.
  • At least a part of the first hollow profile has a circular cross section. Choosing a circular cross section for the first hollow profile simplifies the manufacturing process for the second hollow profile, since the second hollow profile is wound around the first hollow profile and thus follows the first hollow profile's periphery.
  • the nominal width of the first hollow profile is equal to or larger than 20 mm and smaller than 120 mm.
  • the present embodiment ensures a sufficiently fast flow rate of the first medium. Keeping the nominal width of the first hollow profile below 120 mm ascertains that the first medium flows slow enough to provide sufficient thermal coupling between the first medium and the second medium.
  • the nominal width of the second hollow profile is equal to or larger than 5 mm and smaller than 25 mm.
  • the nominal width of the second hollow profile is equal to or larger than 5 mm and smaller than 25 mm.
  • a heat pump comprising the heat exchanging device according to the present invention, wherein the heat exchanging device is employed as one of an evaporator or a compressor.
  • a domestic appliance preferably one of a washing machine or a dishwasher, comprising a heat pump according to the present invention.
  • a method of operating a heat exchanging device comprises the steps of: conducting a first medium in a first hollow profile; conducting a second medium in a second hollow profile, wherein at least a part of the second hollow profile is wound around at least a part of the first hollow profile; wherein a nominal width of the second hollow profile is smaller than a nominal width of the first hollow profile; wherein an outer surface of the first hollow profile comprises a first contact portion, wherein an outer surface of the second hollow profile comprises a second contact portion, and wherein the first contact portion and the second contact portion are coupled by means of a soldered connection.
