SHELL-AND-TUBE CONTINUOUS HEAT EXCHANGER Russian patent published in 2016 - IPC F24D7/00 F28F1/02 F28D7/16 

FIELD: heating.

SUBSTANCE: straight-flow shell-and-tube cylindrical heat exchanger for gases and fluids with heating or cooling medium intake and discharge pipes at its ends features single-arrow arrangement of the shaped tubes along the lateral cylindrical surface. Cooling or heating medium is fed via inlets and outlets are arranged in circles at ends between the sidewall of heat exchanger and the pipe that make the tube plate elements. Note here that the heat exchange tubes feature the wedge-like cross-section over the main length with acute angles facing the central axis. This allows a uniform filling of heat exchanger. Note also that the tube cross-section decreases to cooling or heating medium feed or discharge points for tubes to be connected to the bores in heat exchange circular ends.

EFFECT: decreased irregular distribution of tube medium, higher efficiency of heat exchange.
