Definitions

  • the invention relates to a heat exchanger, in particular a water-air heat exchanger or an oil-water heat exchanger according to claim 1, and a method for producing a heat exchanger, in particular a water-air heat exchanger or an oil-water heat exchanger according to claim 6.
  • EP 2 466 241 A1 describes an oil-water heat exchanger with several pan elements stacked on top of one another and soldered together.
  • Such oil-water heat exchangers are usually integrated into the cooling circuit of internal combustion engines and can be used, for example, to cool the engine oil.
  • an electric heater is proposed there in an interior space of the heat exchanger in order to heat one of the interacting fluids of the heat exchanger.
  • DE 10 2013 010 907 A1 shows an electrical heating device for heating a first medium and a second medium according to the preamble of claim 1, comprising at least one pipe carrying the second medium, a heat exchanger which is in thermally conductive contact with the at least one pipe and which carries the first medium, and a Layer heating element that at least partially covers the surface of the at least one tube.
  • FR 2 966 580 A1 shows a heat exchanger which has a collector box for receiving a coolant and a radiator in which the coolant is circulated.
  • the collector box contains an electrical heating element, for example an electric immersion heater, which is provided with an active part which extends into an internal volume defined by the collector box.
  • heaters are described that have an electrical heating layer that heats up when an electrical voltage is applied (or when a current flows).
  • DE 10 2011 006 248 A1 A household refrigerator with a heating device is described there.
  • the heating device is produced as a layer heater by painting and applied to a surface of an evaporator of the household refrigerator.
  • the stratified heating is according to DE 10 2011 006 248 A1 Directly applied over a surface of the evaporator and hardly thermally insulating in order to impair the functionality of the evaporator as little as possible.
  • it is considered to be disadvantageous that the production according to this prior art is comparatively complex and appears to be tailored to a very special application. It is the object of the invention to propose a heat exchanger which enables a fluid flowing through the heat exchanger to be heated in a simple and effective manner.
  • a heat exchanger in particular water-air heat exchanger or oil-water heat exchanger, comprising at least one first fluid channel for guiding a first fluid (e.g. oil from an oil-water heat exchanger or water from a water-air heat exchanger ), as well as at least one second fluid channel for guiding a second fluid (e.g. water of the oil-water heat exchanger or air of the water-air heat exchanger), the at least one first fluid channel being connected to a fluid receiving volume (in particular the outlet side), the fluid receiving volume is equipped with an electrical heating coating, wherein the fluid receiving volume is provided by a separate module, wherein the separate module can be or is attached to the remaining components of the heat exchanger.
  • the heat exchanger can generally be a liquid-liquid heat exchanger or a liquid-gas heat exchanger or a gas-gas heat exchanger.
  • a core idea of the invention is that of the per se, for example WO 2013/186106 A1 or WO 2013/030048 A1 known electrical heating coatings to apply to a fluid receiving volume which is connected to at least one of the fluid channels.
  • a fluid to be heated with the heat exchanger can effectively be additionally heated or the temperature of a heating fluid can be increased further (in particular if the electrical heating coating is connected on the inlet side to a fluid channel of the heating fluid).
  • a fluid can be effectively heated, for example an oil of an oil-water heat exchanger for an internal combustion engine of a motor vehicle can be heated.
  • the heat exchanger can have several first fluid channels and / or several second fluid channels.
  • the fluid receiving volume is a volume of the heat exchanger before (or after) the fluid is distributed to a plurality of individual fluid channels (that is to say, for example, a fluid collecting device or fluid distributing device).
  • the first fluid can be oil or water.
  • the second fluid can be water or air.
  • the first and / or second fluid can be liquid or gaseous.
  • the fluid receiving volume is defined by a fluid receiving container, in particular an oil receiving container.
  • a fluid receiving container in particular an oil receiving container, is preferably connected on the outlet side to one or more fluid channels through which oil preferably flows.
  • the fluid receiving volume can be defined by a connection pipe, in particular an outlet pipe, preferably an oil-water heat exchanger.
  • a connection pipe in particular an outlet pipe, preferably an oil-water heat exchanger.
  • a turbulator can be provided. This is preferably provided in the vicinity of an electrical heating coating (ie in particular not further than 5 cm, in particular 2 cm away).
  • the turbulator can be arranged inside the outlet pipe (provided with an electrical heating coating).
  • the electrical heating coating can be arranged on an outer wall of the fluid receiving volume (for example outlet pipe) or on an inner wall of the fluid receiving volume (for example outlet pipe). If a turbulator is provided, it can optionally also be provided with an electrical heating coating itself.
  • the fluid receiving volume is provided by a separate module, the separate module being attachable or being attached to the other components of the heat exchanger.
  • a separate fluid receiving volume is proposed so that existing heat exchangers (in particular oil-water heat exchangers) can be further improved by a simple upgrade.
  • the modular design of the fluid intake volume also has the advantage that manufacturing costs can possibly be reduced, for example by using the same fluid intake module for different types and / or sizes of heat exchangers.
  • the heating coating is particularly preferably designed for operation in the low-voltage range, preferably for 12 volts, 24 volts or 48 volts.
  • Appropriate electrical and / or electronic components of the oil-water heat exchanger are then preferably also designed for such a low-voltage range (12 volts, 24 volts or 48 volts).
  • "Low-voltage range” should preferably be understood to mean an operating voltage of less than 100 V, in particular less than 60 V (direct current).
  • the heating coating is applied indirectly, in particular via an insulation layer, to or in the fluid receiving volume.
  • an insulation layer can be formed, for example, by an adhesion promoter layer or attached to the oil-water heat exchanger via such a layer.

Overall, simple yet adequate electrical insulation is provided (especially in low-voltage applications).
  • the heating coating can even be applied directly to or in the fluid receiving volume (for example in low-voltage applications and / or if the substrate is not or only poorly electrically conductive).
  • the heating coating and / or insulation layer is preferably applied over the entire surface of the fluid receiving volume.
  • the heating coating and / or the insulation layer can have an (at least essentially) constant layer thickness.
  • the heating coating and / or the insulation layer can per se be designed to be dimensionally unstable (or not self-supporting).
  • a substrate can be dispensed with, so that the heating coating (and an optional insulation layer) may be formed free of a substrate.
  • a possibly necessary carrying and / or support structure can be provided by the fluid receiving volume (or a wall of the same).
  • the heating coating can be materially connected to a surface, in particular an outer and / or inner surface, of the fluid receiving volume.
  • the heating coating is designed as a continuous (in particular unstructured and / or uninterrupted) layer.
  • the heating coating can generally have at least one section within which there are no interruptions in the heating coating in two mutually perpendicular directions over a distance of at least 1 cm, preferably at least 2 cm, even more preferably at least 4 cm.
  • the heating coating can comprise at least one rectangular section with a length and a width of at least 1 cm, preferably at least 2 cm, even more preferably at least 4 cm, within which there are no interruptions or possibly other structures in the heating coating.
  • An “interruption” within the heating coating is to be understood as a section through which no current can flow, for example because this section remains (completely) free of material and / or is (at least partially) filled with an insulator.
  • the heating coating can be (thermally) sprayed on (regardless of whether it is unstructured or structured, in the final state). In this context it has surprisingly been found that even such a simply configured heating coating can bring about sufficient heating of the oil.
  • the heating coating is designed as a structured layer.
  • the heating coating is preferably structured by a masking process (preferably using silicone, which can be embossed).
  • a masking process preferably using silicone, which can be embossed.
  • the insulating layer described above can have a thickness of at least 50 ⁇ m, preferably at least 200 ⁇ m and / or at most 1000 ⁇ m, preferably at most 500 ⁇ m.
  • the heating coating preferably has a height (thickness) of at least 5 ⁇ m, preferably at least 10 ⁇ m and / or at most 1 mm, preferably at most 500 ⁇ m, even more preferably at most 30 ⁇ m, even more preferably at most 20 ⁇ m.
  • a conductor path defined by the heating coating can be at least 1 mm, preferably at least 3 mm, even more preferably at least 5 mm, even more preferably at least 10 mm, more preferably at least 30 mm wide. “Width” should be understood to mean the extension of the conductor track perpendicular to its longitudinal extension (which usually also defines the direction of the current flow).
  • a protective cover for example a silicone protective layer, is attached over the heating coating.
  • the heating coating can also define an outside or inside of the fluid receiving volume (in an embodiment that is particularly easy to manufacture).
  • the oil-water heat exchanger has a plurality of modules, in particular tub elements, which further preferably, as in FIG EP 2 466 241 A1 described, can be formed.
  • the oil-water heat exchanger (apart from the fluid holding volume according to the invention) as in EP 2 466 241 A1 or US 2015/0176913 A1 described, be formed.
  • the disclosure of these documents is hereby explicitly incorporated by reference.
  • at least one heating coating can be arranged between two modules.
  • the oil-water heat exchanger comprises several pan elements, at least one heating coating can optionally be arranged (applied) between two of these pan elements (on one of the pan elements).
  • an additional heating coating can be applied to further surfaces of the heat exchanger.

If necessary, the electrical heating coating can be sprayed on (thermally).
  • passivation oxygen, in particular anodizing
  • the electrical heating coating can be sprayed on (thermally).
  • the above-mentioned object is also achieved by using a heat exchanger of the type described above or produced according to the type described above, as a water-air heat exchanger or as an oil-water heat exchanger, in particular for the internal combustion engine of a motor vehicle.
  • the insulating layer can be a ceramic material or a polymer material or consist of such a material, Al 2 O 3, for example, being considered as the ceramic material.
