HEAT-EXCHANGER Russian patent published in 2006 - IPC F28D7/16 F28F9/22 

FIELD: heat-exchangers, particularly submersible ones.

SUBSTANCE: heat-exchanger comprises body perforated with orifices located at cylindrical inlet chamber height, tube plate, tube bundle arranged so that coolant is directed transversely to the tube bundle. Heat exchanger also has displacers and spacing grid. Hexahedral collector is formed on tube bundle at inlet chamber height so that the collector is coaxial to the body. The hexahedral collector perimeter is free of tubes. Radial channels extend from collector corners to tube bindle perimeter. The radial channels are also free from tubes. Displacers are installed in spacing grid below inlet chamber.

EFFECT: possibility of uniform coolant flow over each heat-exchanging tube, provision of equal temperature characteristics at each tube outlet and reduced vibration of tubes in tube bundle.
