Abstract

The invention makes it possible to increase the heat output of the heat exchanger by ensuring its multi-pass rate. In the frame adjoining the tube plate 2, a bundle of U-shaped tubes 3-5 is placed, arranged in a checkerboard pattern. The inlet manifold 6 with nozzle 7 and the outlet collector 8 with nozzle 9 are separated by a partition 10 and additional partitions 11 into compartments 12-15. The partitions 10 and 11 are provided with overflow holes 16. Each U-shaped tube 3-5 is bent in one plane and communicated with adjacent compartments 12-15 of collectors 6 and 8. Turbulyzers are installed in the annular space in the form of undulating plates. 6 Il.
