Abstract: An electrical interconnect for use in connecting layers of a multi-layer heater includes a shaped body having a lower end portion and an upper end portion. The lower end portion has a smaller contact area than a contact area of the upper end portion, and the contact area of the lower end portion is proximate a heating layer and the contact area of the upper end portion is proximate a routing layer.

Abstract: A heating system component for a heating system for heating a fluid medium is provided. The heating system component includes: a carrier unit comprising a wet side, wherein said wet side corresponds to a surface of said carrier unit configured to be in contact with said fluid medium; and a heating unit. The heating unit may be coupled to the carrier unit via soldering, laser welding, gluing, ultrasonic welding, and/or friction welding. The carrier unit may comprise aluminum.

Abstract: The present disclosure relates to a heating system component including a temperature monitoring and/or control unit comprising a lower surface, and a carrier unit comprising an upper surface. At least a part of said lower surface of said temperature monitoring and/or control unit is in thermal contact with at least a part of said upper surface of said carrier unit. Said lower surface of said temperature monitoring and/or control unit and said upper surface of said carrier unit are attached to each other by means of a welded seam, preferably by means of a laser-welded seam.

Abstract: A rotor unit for a brushless direct current motor (BLDC motor) comprises a main body integrally formed with a rotor shaft and an annular ring magnet mounted on the main body. The annular magnet comprises an anisotropic hard ferrite and is laterally magnetized. The rotary shaft and the main body of the rotor unit may be formed from one plastic material. The rotor unit is supported within the BLDC motor via self-lubricating bearing seats.

Abstract: A heating system for heating fluid media including a carrier unit, a heating unit arranged on the carrier unit and a heat transfer element arranged on the carrier unit and includes a material which is a good conductor of heat, which heat transfer element has a first mounting portion for mounting a first safety device which responds at a first response temperature and a second mounting portion for mounting a second safety device which responds at a second response temperature which is lower than the first response temperature, which heat transfer element has a first temperature pickup portion which is in direct heat-conducting contact with the heating unit and the first safety device. The heat transfer element has a second temperature pickup portion is spatially separate from the first temperature pickup portion and in heat-conducting contact with the medium to be heated and the second safety device.

Abstract: A tubular heating element for heating fluid media, in particular for household appliances, comprising a jacket pipe inside which there is disposed at least one heating coil made of an electrical resistance heating wire and embedded in an electrical insulation material, the heating coil having a first and a second terminal portion by means of which the heating coil is connected to a source of current via at least one connection element at each end, and at least one operating portion extending between the two terminal portions of the heating coil. It is further specified that the diameter of said heating coil increases at at least one terminal portion in the direction of the operating portion.
