STACKED DISC HEAT EXCHANGER FOR A THERMAL MANAGEMENT MODULE

Abstract

A stacked disc heat exchanger for a thermal management module may include a plurality of stacked discs arranged following one another in a stacking direction. Each stacked disc of the plurality of stacked discs may include a bottom extending transversely to the stacking direction. An outermost disc of the plurality of stacked discs in the stacking direction defining a cover disc. The cover disc may include at least one convexity formed in the stacking direction towards an outside. The at least one convexity may extend transversely to the stacking direction and may form a channel for a flow path extending through the stacked disc heat exchanger of a fluid. The cover disc may further include at least one opening that is open in the stacking direction towards the outside for fluidic connection with the thermal management module.
