Abstract
In a method for producing a heat exchanger tube bundle for a heat exchanger of an electrochemical energy accumulators, heat exchanger channels and an intended profile are incorporated into material strips by deep drawing. A forward-flow distribution aperture is incorporated into a first such material strip from step b) (first heat exchanger plate), and return collecting apertures are incorporated into a second such material strip, forming first and the second heat exchanger plates. The latter are aligned in such a manner that webs of the two heat exchanger plates border each other, and the heat exchanger channels form heat exchanger tubes. The heat exchanger plates arranged in this manner are joined together to form a heat exchanger tube bundle. A corresponding pressure welding apparatus, a heat exchanger tube bundle, a heat exchanger module, a heat exchanger with two or more heat exchanger modules, and an electrochemical energy accumulator with a heat exchanger of this type are also disclosed.
