HEAT EXCHANGER Russian patent published in 2019 - IPC F28D7/16 F28F9/26 

FIELD: heat exchange equipment.

SUBSTANCE: invention relates to heat exchange equipment and can be used in various industries, communal and agricultural industries, mainly in industrial biogas plants. Heat exchanger comprises horizontally oriented cylindrical housing, bulged bottoms with seats, pipes medium supply and discharge branch pipes, inlet and outlet tubes of the tube medium, heat exchange elements in the form of tube bundles fixed at opposite ends in tube plates, which are fixed in opposite saddles. Central bundle of tubes is located along longitudinal axis of housing, and side bundles of pipes are located at distance from longitudinal axis at equal distance from each other. On one side of the housing, the central seat is connected to the pipe heat carrier supply pipe, and the side seats are connected to the collecting receiver inputs, the outlet of which is connected to the pipe heat carrier discharge branch pipe. On the other side of the housing, the central seat is connected to the inlet of the distribution manifold, the outlets of which are connected to the side seats, with possibility of pipe medium flowing in forward direction through central tube bundle and in reverse direction through side bundles of pipes, which realizes two-way heat exchange of heating medium.

EFFECT: technical result consists in improvement of heat exchanger efficiency and reduction of metal consumption of its manufacturing.
