THERMOELECTRIC DEVICE FOR PRESTART HEATING OF STATIONARY ICE Russian patent published in 2019 - IPC F02N19/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, in particular to heating systems for combustion engines in the winter time for remote start. Device for prestart heating of stationary ICE includes first thermoelectric section consisting of thermionic converters, each consisting of a pair of sections made of different metals M1 and M2, ends of which are interconnected by soldering or welding, forming a zigzag-shaped row in the form of an open circle and an annular channel between the row and the outer surface housing, wherein the lengths of the metal sections M1 and M2 are selected such that the upper junctions of the zigzag row are located in the area of the base of the flame, the lower junctions of the above row are located near the lower end of the lower branch pipe, and the current leads are connected to the collectors with similar charges connected to the converter, where required voltage and current for required battery charging are created; heat chamber box bottom is provided with slots in which straight zigzag-like rows are inserted, consisting of thermionic converters, interconnected at ends by bridges and electric capacitors, forming second thermoelectric section, wherein lengths of metal sections M1 and M2 of thermionic transducers is selected such that upper junctions of rows of second thermoelectric section are located in zone of heat chamber, and lower aforesaid lines of the rows are located outside the bottom of heat chamber, part of thermionic converters sections located in slots are placed into planks made of dielectric material, terminal leads of the second thermoelectric section are connected to collectors with similar charges connected to the converter, where required voltage and current are generated for recharging of the accumulator; crankcase heating assembly consists of a heat pan forming between it and casing a gas gap equipped with several lower nozzles, in which, as in the heat chamber, gas burners without thermoelectric sections are inserted, similar to the device with the gas burner of the heat chamber, connected from below to the distributing pipeline.

EFFECT: higher efficiency of thermoelectric device for prestart heating of stationary ICE.
