Liquid-cooled electrical assembly

In a liquid-cooled electrical assembly containing an arrangement for cooling at least one electrical component with current flowing through it and having a coolant liquid flowing into an inlet of a cooler and heated-up coolant removed from the cooler through an outlet, the improvement which comprises:

• the cooler comprising substantially sheet-like cooling elements each having an inlet opening and an outlet opening for the coolant;
• the cooling elements and electrical components being alternately stacked together to form a pile;
• the inlet opening of each cooling element being directly connected with a liquid coolant inlet of the cooler;
• the outlet opening of each cooling element being directly connected with a liquid coolant outlet of the cooler;
• each said electrical component comprising at least one sheet-type resistive element making up a resistor;
• each of said resistive elements contain conductive paths deposited on an insulating substrate in a non-inductive pattern in a current-compensating manner;
• said resistive elements having electrical contacts;
• an electrical contact of a first resistive element being connected by a welding seam located outside of the cooling element to an electrical contact of a second resistive element separated from the first one by a cooling element;
• said cooling element being connected to a defined potential;
• and
• each cooling element is held at the same potential as the electrical contact of a neighboring resistive element.
