PLATE HEAT EXCHANGER WITH PLUG-IN TURBULATORS Russian patent published in 2023 - IPC F28D9/02 F28F3/02 F28F13/12 

FIELD: heat power engineering.

SUBSTANCE: used in plate heat exchangers. In a plate heat exchanger with insert turbulators, containing a horizontal casing made in the shape of a rectangular parallelepiped, the top, bottom and ends of which are made in the form of upper and lower tube sheets with rectangular holes and two end tube sheets with rectangular holes, a package consisting of heat exchange plates installed between the upper and lower tube sheets and the end tube sheets with the formation of vertical channels communicating with each other with holes in the upper and lower tube sheets and horizontal channels communicating with the holes of the end tube sheets, which, in turn, are closed by the top, bottom and end covers, covering the casing at the top, bottom and ends, wherein the end covers and the top and bottom covers are equipped with inlet and outlet pipes, and in the vertical and horizontal channels there are inserted turbulators made of stainless material, the length and height of which are determined by the corresponding dimensions vertical and horizontal channels, each turbulator consists of upper and lower brackets, interconnected by vertical swirlers with vortex blades, attached along the length of the swirlers in pairs and crosswise opposite each other and equipped at the ends with removable U-shaped clamps connected to locking rings.

EFFECT: increasing the efficiency and reliability of a plate heat exchanger with plug-in turbulators.
