  • Heating Device For Use Thereof In A Vehicle
    Publication number: 20200317027
    Abstract: The present invention relates to a heating device for heating fluids, such as water or a liquid coolant, for example, which can be applied in electric or hybrid vehicles, for example, where the absence of an internal combustion engine or its shorter time of use requires using heating devices for heating either the passenger compartment or other parts of the vehicle that require it. The present invention is characterized by a configuration which limits the temperature to the temperature at which heat exchange occurs between the heat generation source and the liquid to be heated, such that the liquid does not generate precipitates, prolonging the service life of the device.
