Heating Block for Heating Water

摘要

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.

1: A heating block for heating a liquid medium, comprising:
a heating block body with a cavity for receiving or guiding the medium; an electric heating element arranged in the cavity, and configured to heat the medium by means of electric current passing through the heating element; a semiconductor switch configured to control the electric current flowing through the heating element so as to control a heating power of the heating element; and a closure piece configured to close an opening in the heating block body to the cavity element; wherein the semiconductor switch is electrically and thermally conductively connected to the closure piece by a first connection terminal, such that an electrical connection of the first connection terminal to the heating element is carried out via the closure piece and a thermal connection of the first connection terminal to the medium is carried out via the closure piece; and wherein 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.
