HEAT EXCHANGER

摘要

A heat exchanger made from seamless or welded and drawn tubes. A first layer of tubes (13) is laid onto a base plate (10) so that the tubes lie parallel to sidewalls (12A, 12B). A similar layer running at right angles to the first and sitting on an intermediate plate (20), is laid on top of the first layer. The packing is arranged such that when heat and loading is applied to the composite structure in a vacuum, the tubes (13) are deformed and are bonded to the plates with the sidewalls (12A, 12B) being bonded to the plate above.
