HEAT EXCHANGE UNIT Russian patent published in 2017 - IPC F28D7/00 

FIELD: heating.

SUBSTANCE: in the heat exchange unit the feeding medium manifold 2 is made in the cover 4. The central cavity 5 is connected to the inclined channels 6 with the peripheral cavity 7 and the suppling feeding medium pipes 8. The suppling feeding medium pipes 8 are fixed at the cover 4 and disposed coaxially to the discharge pipes of feeding medium 9, placed in the tube plate holes 10. Tube plate 10 forms with the cover 4 the cavity 11 for removing the feeding medium. At that each discharge pipe 9 is provided with the adapter 12, one end of which is fixed in the tube plate 10 and another with the ability of axial displacement is connected to the discharge pipe 9. The discharge tube 9 is installed with a gap relative to the holes in the tube plate 10 and it has the ring projection 13, which is in contact with the inner wall of the indicated hole with the ability of axial displacement, i.e. it is mobile support of the module 3.

EFFECT: alignment of the temperature field of inlet and discharge heat exchanging pipes by eliminating cold flashes of the feeding medium on the body and the heat transfer surface.
