Abstract: A heating device for heating fluids, such as water or a liquid coolant, for application in electric or hybrid vehicles, 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 heating device is provided with 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.

Abstract: The present invention relates to a heating device for use in vehicles, particularly to a device for heating a fluid, for example air, water, or liquid coolant. The device is particularly designed for vehicles the main propulsion system of which is not a combustion engine and which therefore lack residual heat from the engine. The present invention is characterized by the use of a chassis with a planar configuration and an inner chamber in fluid communication with an inlet port and an outlet port and a heating plate. The chassis comprises at least one window and the heating plate has a heating region closing the window of the chassis for heating the fluid housed in the inner chamber.

Abstract: The present invention relates to a fin body intended for being housed inside a heat exchange tube which is one from among heat exchange tubes showing a planar configuration. The fin body is configured in the form of a plate, this plate being the one inserted into the heat exchange tube. The plate is configured from a metal sheet bent into a plurality of consecutive bends. The invention is characterized by a range of characteristic width to height ratio in the interval of 0.15-0.5, and according to more specific cases, in the lower subranges. As a result, the fin gives rise to a heat exchange tube with a higher efficiency than fins known in the state of the art without penalizing the pressure drop.
