Abstract: A PTC thermistor module may include at least two PTC thermistor elements. The at least two PTC thermistor elements may be spaced apart from one another by separation sections. The at least two PTC thermistor elements may include two electric lines, spaced apart from one another, for the electrical supply of the PTC thermistor elements. An increased efficiency and operational reliability of the PTC thermistor module are achieved with an electrically insulating receiving body, in which the PTC thermistor elements are received, and which encompasses the PTC thermistor elements in a circumferential direction. A method for producing such a PTC thermistor module and a temperature control device may utilize at least one such PTC thermistor module.

Abstract: An electrical heating element, in particular for a heating or air-conditioning system of a motor vehicle, having a heating block, which includes a plurality of electrical heating elements having heaters and having contacts, which electrically contact the heaters, the heating block including a plurality of radiator elements, which are thermally connected to the heaters for the purpose of transferring heat from the heaters to a medium flowing against the radiator elements, the heaters having two diametrically opposed, wide side surfaces and two diametrically opposed, narrow side surfaces. The contacts electrically contact the heaters on the diametrically opposed narrow side surfaces, or the contacts electrically contact the heaters on the diametrically opposed, wide side surfaces in diagonally opposite areas, viewed laterally, which are each adjacent to one of the diametrically opposed, narrow side surfaces.
