THERMOELECTRIC GENERATOR IN INTERNAL COMBUSTION ENGINE EXHAUST GASES EXHAUST SYSTEM Russian patent published in 2017 - IPC F01N5/02 H01L35/30 H01L35/34 

FIELD: engines.

SUBSTANCE: invention can be used in automotive internal combustion engines. Thermoelectric generator is arranged in internal combustion engine exhaust gases exhaust system. Thermoelectric generator consists of hot heat exchanger (1) and thermoelectric modules (4) installed on hot heat exchanger (1). Hot heat exchanger (1) has regular polygonal longitudinal shape with lengthwise finning with longitudinal fins (2) variable-length profile. Above thermoelectric modules (4) cold heat exchangers (5) are installed with fluid flow, flowing against direction of exhaust gases flow. Cold heat exchangers (5) are tightly pressed to thermoelectric modules (4) plates and via them are pressed to common hot heat exchanger (1) screwed-in into pressing plates (9) by screws (8) with resilient compensation elements.

EFFECT: technical result consists in enabling of temperatures distribution uniformity along heat exchanger length.
