Abstract

A heating block including a heating block body which receives/guides a liquid medium, an electric heating element arranged in the cavity for heating the medium via electric current, a semiconductor switch for controlling the electric current flowing through the heating element to control a heating power of the heating element, and a closure piece for closing an opening in the heating block body to the cavity element. The semiconductor switch is electrically and thermally conductively connected to the closure piece via first connection terminal to electrically connect the first connection terminal to the heating element via the closure piece, and to thermally connect the first connection terminal to the medium via the closure piece. The semiconductor switch is directly connected to a control board by a second connection terminal so that the semiconductor switch is spatially arranged and mechanically connected directly between the control board and the connection piece.
