Abstract: A cooling module for batteries of an electric or hybrid vehicle that has a coolant supply line, a coolant discharge line, and flat tubes arranged side by side, between which there is space for batteries to be cooled. Each of the flat tubes is connected to the coolant supply line and the coolant discharge line. The flat tubes each carry connectors and the coolant supply line and the coolant discharge line are each assembled from a plurality of line segments connected by a connector of one of the flat tubes to one of the connectors of an adjacent flat tube.

Abstract: The present description relates to a flat heat exchanger of the types which use a single working fluid circulating continuously through the inside of one or a plurality of heat transmission conduits for cooling one or more electric or electronic components or the like located in a position close to or in contact with a region of the outer part of at least one heat transmission conduit.
