Abstract: An electric heating device, in particular for mobile applications, having a substrate and a heat conductor layer formed on the substrate. The heat conductor layer is interrupted by at least a first isolating interruption, the first isolating interruption separating at least a first and a second layer portion of the heat conductor layer from one another. The first layer portion is connected at a first end to a first terminal, for example positive pole, and the second layer portion is connected at a first end to a second terminal, for example negative pole. The first layer portion is connected at a second end to the second layer portion and is connected via this second layer portion to the second terminal.

Abstract: A heat exchanger and a method of manufacturing a heat exchanger having an internal conduit for conducting a fluid, and a heat dissipating body for dissipating heat of the fluid. The heat dissipating body has a cavity extending in a longitudinal direction. An end piece of the internal conduit extends inside of the cavity and has an orifice facing a bottom surface of the cavity for feeding the fluid into a bottom area of the cavity. An inner shell of the heat dissipating body includes a first portion and a second portion, each portion having at least two ribs transversally displaced in relation to each other. At least one rib of one of the first and the second portion is transversally displaced in relation to each rib of the other of the first and the second portion.

Abstract: The invention relates to a heating device (10) for a vehicle, comprising: a flow path (14, 16, 20, 22, 24) for a liquid heat transfer agent; an electric heating device (34) for generating heat and for releasing generated heat to the heat transfer agent on a heating portion (20) of the flow path; and an electronic controller (26) for controlling a heat output of the heating device. The controller (26) is provided with a heat releasing body in order to release waste heat of the controller (26) to the heat transfer agent on a preheating portion (16) of the flow path upstream of the heating portion (20). The invention likewise relates to a method for cooling the controller.

Abstract: A heating device for a vehicle and a method for operating the heating device includes a flow path for a heat transport medium and an electrical heating arrangement for heating the heat transport medium on a heating section of the flow path. The heating section has at least two channels running in a serpentine pattern, through which the heat transport medium can flow in parallel.

Abstract: The invention relates to a heat exchanger (10) having an internal conduct (32) for conducting a fluid, and having a heat dissipating body (12, 12?) for dissipating heat of the fluid, wherein the heat dissipating body (12, 12?) having a cavity (14, 14?) extending in a longitudinal direction (36), at least one end piece (34) of the internal conduct (32) extending inside of the cavity (14, 14?) the end piece (34) having an orifice (42) facing a bottom surface (44) of the cavity (14, 14?) for feeding the fluid into a bottom area of the cavity, wherein between an outer shell (48) of the internal conduct (32) and an inner shell (20, 20?) of the heat dissipating body (12, 12?) a streaming space for conducting the fluid away from the bottom (46) is provided, the streaming space extending in the longitudinal direction (36).
