Concentric tube heat exchanger and end seal therefor

摘要: A concentric tube heat exchanger comprises an outer and a inner tube, with annular passageway between the tubes. The ends of are sealed by sealing members having axially extending walls which connected to one another respective member preferably integrally formed connecting wall. resilient diverge so as form friction fit tubes during assembly exchanger. further turbulizer plurality rows corrugations defining flow passages. Preferably, have top land width greater than bottom that side corrugation radially arranged in passageway. Adjacent each row offset relative amount from about 30 percent 40 percent.
