  • each coil tube is the same.
  • a heat exchanger comprising at least one axial divider wall extending between the outer surface of the core and the inner surface of the body and having holes for coil tubes.
  • a heat exchanger comprising at least one radial divider extending from either the outer surface of the core or the inner surface of the body in between the coil tubes creating one or multiple flow paths for the second liquid.
  • the ninth aspect of the invention there is provided a heat exchanger wherein the axial dividers comprise multiple holes.
  • a heat exchanger wherein the coil tubes (6, 7, 7xx) are single continuous pipes without splices or joints.
  • the heat exchanger described herein is primarily for collecting heat energy or for dissipating heat energy for cooling using sea- river or lake water or other water bodies having sufficient volume.
  • the heat exchanger is usable in waters at low temperatures, even close to the freezing temperature.
  • the heat exchanger is suitable for connecting to a heat pump system for either collecting heat to a heat pump circuit or for dissipating heat from the circuit.

  • a coil tube assembly for the first liquid is fitted in the flow path of the secondary liquid.
  • the heat exchanger is preferably made of plastic, for example polyethylene or polypropylene.
  • FIGURE 1 illustrates a heat exchanger in accordance with at least some embodiments of the present invention.

  • the shape of the heat exchanger tubing 2 has a first part 4 formed as a cone and a second part 5 formed as a cylinder.
  • the diameter of the cylinder is the same as the largest diameter of the cone, so these diameters match each other.
  • a body 3 forms the outer casing of the heat exchanger.
  • the outer surface of the body is cylindrical.
  • the inner surface of the body is also cylindrical, but has a lining wall 13 extending from the inner surface of the cylinder towards the core 1.

  • the inner wall of the body 3 with the lining wall 13 and the outer surface of the core 1 form a flow path for a liquid.
  • This liquid is the second liquid, that functions as a volume from which the heat is collected from or to which it is dissipated.
  • the second liquid is usually water, as it is easily accessible in large enough volumes. However, any other liquid may be used, as long as the materials and structure of the heat exchanger is capable of handling such liquid, e.g. waste water, process water.
  • the second liquid is fed to the heat exchanger through an intake 14 that is placed over the top of the heat exchanger tubing 2 when the heat exchanger is in vertical position in relation to the ground, i.e. the central axis of the core and the heat exchanger being placed on a right angle in relation to the ground. From the intake 14 the second liquid flows on a screen 15.
  • the screen 15 is a plate having holes in it. This simple part effectively divides the second liquid over the heat exchanger tubing placed under it.
  • the second liquid flows by the gravity downwards over the heat exchanger tubing and releases heat to the first liquid flowing in the heat exchanger tubing 2. Consequently the temperature of the second liquid decreases.
  • the action is obviously the opposite.
  • the heat exchanger may be used even in cold waters having temperature only few degrees above zero, even at a range from 0,5 - 5°C, freezing may be a problem.
  • the second liquid flows on the bottom reservoir 16 of the body 3 and exits via outlet 17.
  • the operation and setup of the heat exchanger is described herein in a vertical mounting and operation position.
  • the apparatus may be operated and mounted horizontally, for example, or on an angle to the ground. If such mounting positions are used, forced feeding of second liquid may be needed. This applies to all assemblies when sufficient flow speed can't be achieved by gravity.
  • the force feeding may be accomplished by pumping or using a liquid source placed on an elevated position in relation to the heat exchanger.
  • the first liquid i.e. the liquid used for collecting or dissipating the heat energy
  • the manifold 18 is connected to first ends 9 of each of the coil tubes 6, 7, 7xx of the heat exchanger tubing 2.

  • the second ends 10 of the coil tubes 6, 7, 7xx are connected through a collector 20 to an exit pipe 21.
  • the exit pipe also runs through the core 1.
  • the structure of the heat exchange tubing 2 is described in the following referring to FIGURES 2-6 .
  • the core has axial brackets 22. herein 4, but other number might be used.
  • On these brackets 22 are mounted axial divider walls 11. These axial divider walls 11?? divide the circumference of the heat exchanger tubing in sections, in this case quadrants.
  • the coil tubes 6, 7, 7xx are mounted on these axial divider walls 11?.
  • Each axial divider wall 11 is built of mounting strips 23.
  • the mounting strips 23 have semi-circular seats 24 for a coil tube and fasteners for joining the mounting strips to the brackets and to each other.
  • the seats may have other forms, for example oval or angular.
  • the seat doesn't adapt closely to the outer cross section of the coil tube, the seats allow passage of water between eh mounting strip and the coil tube.
  • the fasteners may be of any convenient kind, for example snap-on clips, rivets, screws, or glue. However, metal parts should be avoided in order to prevent risk of freezing and corrosion.
  • the first mounting strips 23 (4 pcs) are fixed on the brackets of the core 1 and the first coil tube 6 is wound around the core 1 placing the coil tube in the seats 24 of the mounting strips 23.
  • the first end 9 of the first coil tube is placed closest to the first end 8 of the core 1, i.e. closest to the bottom of the heat exchanger.
  • the first coil tube 6 is would around the core until the top wherein the second end of the coil tube 10 is set on a set level.

  • the second end 10 of the second coil tube 7 is set on the same level as the first coil tube 6.
  • Further coil tubes 7xx are mounted in similar fashion by adding mounting strips and successive coil tubes.
  • the first purpose of this structure is to form said cone shape to accommodate the conical shape of the inner wall of the body.
  • the second purpose is to enable using coil tubes having same length.
  • the first ends of the coil tubes are connected to a manifold 18 (18?) and the second ends to a collector 20.
  • the second ends of the coil tubes are set on a same level.
  • radial dividers 12 are set between the rounds of coil tubes.
  • the radial dividers 12 are perforated plates mounted on axial divider walls 11. by trusses 25.
  • the radial dividers 12 are set stepwise over the axial length of the heat exchanger tubing so that every other radial divider plate extends from the outer surface of the core 1 and every other from the inner wall of the body 3.
  • Each of the radial divider plates extend only partially over the radial distance between the inner wall of the body and the outer surface of the body creating stepwise winding flow path. In this way the second liquid is mixed and its temperature is evened out.
  • One feature relates to perforations of the radial dividers 12. The perforations allow second liquid to flow over the coil tube under the radial divider 12 so that the surface of the coil tube is not obscured by the axial divider plate.
  • the apparatus described above and depicted in the drawings is configured by using parts that have circular cross section.
  • Such parts like core, body and connecting pipelines can be conveniently obtained as they are or can be manufactured by using existing apparatuses of plastic industry.
  • the core and body are made of parts having oval cross section.
  • Such configuration may be needed to fit the heat exchanger in shallow heat sources. Any sharply angular cross sections like rectangular or hexagonal are to be avoided as they may create areas where flow speed is decreased, leading to decreased heat transfer and affinity to freezing.
  • the preferred material of the heat exchanger is plastic, in particular polyethylene (PE), polypropylene (PP).
  • PE polyethylene
  • PP polypropylene
  • the bottom of the heat exchanger can be made of a panel made of plastic profiles, e.g. UPONOR WEHOPANEL ® for example.
  • the body may be made of tube made of wound profile.
  • the second liquid is, for example ethanol. This allows for incoming temperatures of the first liquid as low as 0,5 - 1°C.
  • the size of the heat exchanger dimensions of 2,4 m diameter, up to 3 - 4 m high, comprising 13 rounds of coil tubes each having length of 100 - 300 m, can be given. However, the dimensions may be adjusted as required.
  • the structure of the heat exchanger enables dismantling for maintenance and transfer.
  • the apparatus can be operated by gravity or the pressure may be elevated by pumping.
  • the invention can be used for collecting or dissipating heat energy and for providing heat exchangers for collecting or dissipating heat energy.
