SINGLE-PASS SHELL AND TUBE HEAT EXCHANGER Russian patent published in 2014 - IPC F28D7/16 F28F9/02 

FIELD: heating.

SUBSTANCE: in single-pass shell and tube heat exchanger, comprising a cylindrical housing, fittings for input and output of the coolant, the heat transfer tubes, tubular grids, elliptical flanged lids, fittings for input and output of the coolant, respectively - into the elliptical lid and out of the elliptical lid, the elliptical lid with a fitting for input of the coolant is provided with a perforated circular plate with an free cross-section of from 40 to 60% located in the flanging area of the elliptical lid with the fitting of input of the coolant, and the openings in the perforated circular plate are not more than 1.5 times the diameter of the heat transfer tubes.

EFFECT: uniform distribution of the coolant through the heating tubes, increase in heat transfer coefficient with decreasing the heat transfer surface, reducing overall dimensions, material consumption and cost of the heat exchanger.
