  • Such oil-water heat exchangers are usually integrated in the cooling circuit of internal combustion engines and can be used for example for cooling the engine oil.
  • an electrical heater in an interior of the heat exchanger to heat one of the interacting fluids of the heat exchanger.
  • heaters which have an electrical heating layer which heats when an electrical voltage (or the flow of a current) is applied.

  • the object is achieved by an oil-water heat exchanger
  • a core idea of the invention resides in the electrical devices known per se, for example, from WO 2013/186106 A1 or WO 2013/030048 A1
  • Heating coatings (hereinafter an electric heating coating will be referred to as "heating coating” for short) in or on an oil-water heat exchanger, it has surprisingly been found that (even in low-voltage applications - especially below 100V) for example, 12 or 24 or 28 volts), the need for a separate heater (such as that proposed in US 2015/0176913 A1) is eliminated, thus reducing manufacturing costs and the installation space of the oil-water reactor.
  • a comparatively cost-effective production can also be ensured by not having to work as precisely as in high-voltage applications (as described, for example, in WO 2013/186106 A1).
  • a shielding (insulation to the outside) of the electrical heating coating in the present application may possibly be completely dispensed with.

  • Corresponding 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). Especially when used in the low-voltage range, preferably designed for 12 volts, 24 volts or 48 volts.
  • low-voltage range should preferably be understood an operating voltage of less than 100 V, in particular less than 60 V (direct current).
  • the heating coating is on a
  • Heat exchanger cover of the oil-water heat exchanger arranged.
  • Heat exchanger cover (alternatively on an inner side) arranged (applied) be. Even with a low-voltage application, even with an arrangement on the outside of the cover (which may be advantageous, for example, with regard to the contacting), a sufficiently secure use of the oil-water heat exchanger (even without further protection element) is possible. Overall, this proposes a simple yet reliable structure.

  • the heating coating is formed as a structured layer.
  • the heating coating is preferably structured by a masking process (preferably using silicone that can be embossed).
  • a masking process preferably using silicone that can be embossed.
  • Such known masking methods allow a satisfactory structuring and are less complicated than, for example, laser structuring methods which are currently used in the high-voltage range. Overall, therefore, the advantages of a masking process with regard to the present heating coating are exploited in a synergistic manner.
