DEVICE FOR UTILIZATION OF HEAT OF MOBILE POWER PLANT OF DRILLING RIG Russian patent published in 2024 - IPC F02G5/02 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building, in particular to a mobile power plant with internal combustion engines and with means of utilization of engine heat losses, and can be used in drilling of geological exploration wells by using secondary energy resources of an internal combustion engine of mobile power plants. According to the invention, the internal combustion engine heat recovery device contains an internal combustion engine, a fan, a cooling system radiator and three heat exchangers. Device further comprises a unit of thermoelectric generators, connected on one side to the exhaust pipe, on the other side to the vortex pipe, unit of thermoelectric generators is cooled with water in water cooler, which is installed between pump and unit of thermoelectric generators, water, in its turn, is cooled by cold flow coming from vortex tube. Hot end of vortex tube is connected to heat exchanger.

EFFECT: reduction of energy costs during drilling of geological exploration wells due to use of secondary energy resources of internal combustion engine of mobile power plant for production of hot water, as well as generation of electric energy.
