PLATE-TYPE HEAT EXCHANGER Russian patent published in 1998 - IPC

FIELD: thermodiodes for stability or protection of bases of pipe lines, roads, structures, etc in regions at superlow ambient temperature; ceilings and floors of large rooms where temperature control is required. SUBSTANCE: heat exchanger absorbs heat at its lower surface and transfers it through its upper surface due to availability of several rectangular or oval chambers 3 (or cells) in its cross section. Each chamber 3 (or cell) is filled with definite amount of working fluid medium 6. Heat from lower surface 2b of plate 2 is transferred in cells 3 to upper surface 2a of heat exchanger due to evaporation and condensation of fluid medium 6. EFFECT: enhanced thermal efficiency. 5 cl, 6 dwg
