SHIP ENGINE Russian patent published in 2020 - IPC F03G7/06 B63H21/00 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering, particularly, to nonconventional converters of thermal energy into mechanical work. Ship engine consists of heat-sensitive element (HSE) in form of thin-walled pipe, which is working shaft with bearing assemblies and multiplier. Pipe surface outside and/or inside is divided by shells along entire length into two heat zones: heating zone and cooling zone. Hot heat carrier supply and removal channels and coolant channels are connected to heat zones. At the same time the pipe in the middle part is reinforced with an external bushing in contact with the thrust roller at bending of the pipe. Heat carrier supply and removal channels are connected with heat pump heat exchangers. Heat-exchanger for cooling heat carrier is located in heat carrier working agent evaporation circuit, and heat-exchanger for hot heat carrier is in compression circuit behind the compressor.

EFFECT: higher safety during engine operation and reduced environmental pollution.
