WIPO Patent Application WO/2020/218753
Kind Code:
A1
Abstract:
A power generation device according to an embodiment of the present invention comprises: a case comprising a through-hole penetrating same along a first direction so as to form the inner surface thereof; a duct disposed inside the through-hole of the case, a channel being formed in the duct such that a first fluid flows along a second direction perpendicular to the first direction; a first thermoelectric module comprising a first thermoelectric element disposed on a first surface of the duct and a first pin disposed on the first thermoelectric element; a second thermoelectric module comprising a second thermoelectric element disposed on a second surface facing the first surface of the duct, and a second pin disposed on the second thermoelectric element; multiple first guide units coupled to the case and disposed on the duct so as to face each other; and a second guide unit disposed on a third surface formed between the first surface of the duct and the second surface. The second guide unit extends along the second direction between the multiple first guide units. The multiple first guide units and the second guide unit comprise sloping surfaces, respectively, and the inclination angle of the sloping surface of the second guide unit is different from the inclination angle of respective sloping surfaces of the multiple first guide units.
