摘要： A heating device is provided with plates stacked one on top of another. At least one first fluid channel is formed in a fluid-tight manner between a first plate package with a first and a second plate. An electrical heating element is arranged between a first plate of the first plate package and an additional plate. The electrical heating element is accommodated between the two plates in a sealed manner and is electrically insulated, wherein an inlet-side and an outlet side fluid connection of the first fluid channel is arranged on the second plate of the first plate package. The electrical heating element has a connection device for electrical contacting, which is connected to the electrical heating element and protrudes through a window in the second plate of the first plate package, wherein the fluid connections and the window are arranged adjacent to opposing lateral edges of the second plate.

摘要： A heater with a housing with a fluid channel, disposed therein, with a fluid inlet and a fluid outlet, whereby a coil, which generates an alternating magnetic field and is separated sealed from the fluid channel by a coil housing, is provided in the housing, whereby furthermore at least one metallic flat heating element is provided, which can be heated by the alternating magnetic field. The at least one flat heating element is disposed in the fluid channel, whereby the fluid channel is divided at least into a first channel and a second channel. Walls bounding the channels are formed by the coil housing and/or by a flat heating element.

摘要： The invention relates to an operating unit for a vehicle, provided with an operating element (12) having an operating interface (14) with multiple symbol fields (16), to which are assigned operating functions that can be triggered with the actuation of the operating element (12). The operating element (12) is arranged on a support structure (18) such that it can be pressed down in a resettable manner and by means of an actuation object, in particular by means of the finger of a hand. The operating unit (10) is also provided with a mechanical switch (22) which can be actuated when pressing down the operating element (12), a controllable press-down force threshold switching device (34) for switching the force to be overcome to press down the operating element (12) between a first threshold value and a second threshold value that is smaller in comparison to the first threshold value, an actuation sensor system (30) for detecting whether, when the operating element (12) is actuated, the actuation object contacts same within one of the symbol fields (16) of the operating interface (14), and an evaluation and control unit (32) which receives signals from the actuation sensor system (30) or, inter alia, from the actuation sensor system (30), and which only causes the press-down force threshold switching device (34) or, inter alia, the press-down force threshold switching device (34) to switch from the first threshold value to the second threshold value by changing its control, when the actuation object within one of the symbol fields is in contact with the operating interface (14) within one of the symbol fields (16) with an actuation of the operating element (12). An electromagnet or permanent holding electromagnet (40) is used as the press-down force threshold switching device (34).

摘要： The operating device for a vehicle component, in particular a human machine interface (HMI) for vehicles, is provided with a housing, comprising a front wall having a front face in particular with a display surface and a rear face facing away from the front face, and an operating element unit which is positioned and/or can be positioned on and/or in front of the front wall of the housing for manually triggering operating functions and/or for manually adjusting parameters of operating functions for a vehicle component. The operating element unit comprises at least one operating element, a display element and/or a display device, an evaluating and control unit assigned to the at least one operating element and to the display element or the display device, and an energy supply unit. In order to supply electric energy to the energy supply unit of the operating element unit, at least one first coil is arranged so as to face the rear face of the front wall, wherein at least one second coil, which is inductively coupled to the at least one first coil and is connected to the energy supply unit, is arranged in and/or on the operating element unit.

摘要： The application relates to an induction heating device having a housing and a fluid duct. The fluid duct is arranged in the housing and has a fluid inlet and a fluid outlet. Inside the housing is an induction element which generates an alternating magnetic field and which is separated from the fluid duct in a sealed manner by at least one wall. The device also includes at least one metallic areal heating element arranged in the fluid duct which can be heated by the alternating magnetic field.
