Abstract (en)

[origin: WO2015136341A1] A fuel portable heater (1) comprises a combustion chamber (2) with a tubular side wall (3), a housing (7) having a tubular wall (8) extending externally about the side wall (3) of the combustion chamber (2), an annular space (9) formed between the side wall (3) and the tubular wall (8), an electric fan (10) received in the housing (7) and actuatable to convey a heating air flow (11) through the annular space (9), a Seebeck effect thermoelectric converter (12) connected to the side wall (3) in a thermal exchange relationship with the combustion chamber (2) and with the annular space (9), guide surfaces (15) formed in the annular space (9) so as to deviate at least one part of the heating air flow (11) from at least one first circumferential area (16) of the annular space (9) towards at least one second circumferential area (17) of the annular space (9), wherein the thermoelectric converter (12) is located at the second circumferential area (17).
