Beschreibung
Zusammenfassung:	At least one heat-conducting chamber (1) is included in the exhaust pipe of the combustion engine in the cogeneration unit, through which exhaust gases flow. At least one thermoelectric element (2) is placed on at least one outer wall (3) of the heat-conducting chamber (1). The warm side of the electric thermoelectric element (2) adjoins the outer wall (3) of the heat-conducting chamber (1), the cold side of the thermoelectric element (2) abuts a cooler (4) connected directly and/or through a heat exchanger or through a heat pump with the return branch of the heated system. Advantageously, one device includes several heat-conducting chambers (1) lined up next to each other, while one cooler (4) is connected to two cold sides of thermoelectric elements (2) of opposite outer walls (3) of adjacent heat-conducting chambers (1). Thermoelectric elements (2) are preferably connected in series in groups with different numbers, to achieve a balanced total voltage of the group at different temperature drops in different places of the outer wall (3), then the thermoelectric elements (2) are connected to a DC/DC converter. Vo výfukovom potrubí spaľovacieho motora v kogeneračnej jednotke je zaradená aspoň jedna teplovodivá komora (1), ktorej vnútorným priestorom pretekajú spaliny. Na aspoň jednej vonkajšej stene (3) teplovodivej komory (1) je umiestnený elektrický termočlánok (2). Teplá strana elektrického termočlánku (2) prilieha na vonkajšiu stenu (3) teplovodivej komory (1) a na studenú stranu elektrického termočlánku (2) prilieha chladič (4) prepojený priamo a/alebo cez tepelný výmenník, alebo cez tepelné čerpadlo s vratnou vetvou vykurovaného systému. Výhodne jedno zariadenie zahŕňa viacero teplovodivých komôr (1) zoradených vedľa seba, pričom jeden chladič (4) je pripojený k dvom studeným stranám elektrických termočlánkov (2) protiľahlých vonkajších stien (3) susedných teplovodivých komôr (1). Elektrické termočlánky (2) sú vo výhodnom usporiadaní zapojené za sebou do skupín s rozdielnym počtom na dosiahnutie vyváženého celkového napätia skupiny pri rozdielnom teplotnom spáde v rôznych miestach vonkajšej steny (3), následne sú elektrické termočlánky (2) pripojené k DC/DC meniču.
