Recuperator, microchannel - recuperator, film, the use of a film and a method of manufacturing as well as for the operation of a recuperator

摘要

In order to heat exchanger and the microchannel - particularly effectively and to make the same time, very inexpensive to manufacture, the invention proposes that flat stacked thin film layers be arranged in such a way that free spaces in their arrangement in the film channel are two separate microprocessor systems. Also, the use of a perforated or slotted foil or film for the production of a foil stack for a microchannel - heat exchanger is proposed. Likewise, a slotted or perforated film, which is suitable in particular for the production of a foil stack is suitable for a microchannel - heat exchanger. Finally, a process for producing a microchannel - heat exchanger is presented.
