HEAT PIPE AND WASTE HEAT EXCHANGER OF WASTE GAS, WHICH CONTAINS SUCH HEAT PIPE Russian patent published in 2011 - IPC F28D15/02 

FIELD: power industry.

SUBSTANCE: there proposed is heat pipe containing seven sections on the side of heating unit for clean water heating using the heat of waste gas discharged from the engine, and six sections on the side of evaporative unit for evaporation of clean water heated with each section of heat pipe on the side of heating unit using the heat of waste gas, and device for slowing down the speed of clean water flow flowing in sections of heat pipe on the side of evaporative unit. Device for slowing down the flow speed is equipped with a mixing section that mixes the clean water heated with each section of heat pipe on the side of the heating unit on the side of evaporative unit, and in which the cross-section area of continuous-flow circuit is set larger than in each section of heat pipe on the side of the heating unit.

EFFECT: maintaining the effective heat exchange by repeated heating of evaporated steam-phase working fluid medium with heat of waste gas, for example during cold start-up.
