Abstract

The invention relates to a cooling-element part for a cooling element for cooling at least one component of an electrical drive unit of a motor vehicle and can be joined together with a further cooling-element part to form at least one cooling-fluid-carrying cooling duct to the cooling element, and which has a cooling structure configured to increase a flow resistance for the cooling fluid by producing turbulences in the flow having pins that extend at least partially over a height of the cooling duct, wherein the pins are formed as droplet-shaped having a width that decreases in the direction of the flow of the cooling fluid.
