The utility model provides a two casing countercurrent flow wares, belongs to petrochemical, energy -conservation, process equipment equipment technical field for solve the conventional heat exchanger heat transfer degree of depth not high, can not satisfy degree of depth energy -conservation and require the problem. Export characterized by including two equipment casing, heat transfer component, outer tube case or outer concentrated pipe, inner tube case or interior concentrated pipes and tube side import, tube side export, shell side import, a shell side: two equipment casings overlap to be arranged, sets up casing communicating pipe, extradition pipe and inner conduit, casing communicating pipe, extradition pipe upper end are connected with last equipment shell backend and the intercommunication, and the lower extreme is connected with lower equipment shell backend and is fed through, inner conduit is that its upper end of return bend is connected through flange and last inner tube case or interior concentrated pipe, and the middle section is passed and is extradited tub, the lower extreme through the flange under with inner tube case or interior concentrated pipe be connected. Be used for high temperature medium countercurrent flow, improve the heat transfer degree of depth, realize that the degree of depth is energy -conserving.
