Abstract
A method for producing a microchannel bundle heat exchanger (1) includes providing a multiplicity of tubular microchannels (2); incorporating the microchannels (2) in a weaving device; interweaving the tubular microchannels (2) with a plurality of warp wires (3) in the weaving device, and generating at least one heat exchanger mat (4) from the tubular microchannels (2) which are connected to one another by means of the warp wires (3); shaping at least one heat exchanger pack (8) from the at least one heat exchanger mat (4), in particular by folding and/or rolling up the heat exchanger mat (4); and adhesively bonding the tubular microchannels (2) at two mutually opposite end sides (9, 10) of the heat exchanger pack (8).

A method for producing a microchannel bundle heat exchanger, comprising:
- providing a multiplicity of tubular microchannels;
- incorporating the microchannels in a weaving device;
- interweaving the tubular microchannels with a plurality of warp wires in the weaving device, and generating at least one heat exchanger mat from the tubular microchannels that are connected to one another by the warp wires;
- shaping at least one heat exchanger pack from the at least one heat exchanger mat by folding and/or rolling up the heat exchanger mat;
- adhesively bonding the tubular microchannels at opposite ends of the heat exchanger pack by applying adhesive to end regions of the microchannels and curing the adhesive;
- forming at least one radial groove laterally in each of the adhesive at each of the opposite ends of the heat exchanger pack;
- and
- disposing sealing elements respectively in each of the grooves.
