Beschreibung
Zusammenfassung:	The collector has an air-knife (4) i.e. lower air blade, comprising a ventilation opening (6) that is closed or opened by a closing unit i.e. trap door (10). The closing unit comprises an actuating unit with shape memory alloy to open the closing unit beyond preset temperature of the collector. The shape memory alloy is selected among titanium nickel based alloy or copper based alloy, where the shape memory alloy comprises phase changing temperature ranging at 15 degree Celsius. An independent claim is also included for a method for ventilating a heat solar collector. Capteur solaire thermique comprenant une lame d'air (4) comprenant au moins un orifice de ventilation (6), qui peut être fermé ou ouvert par un moyen d'obturation, caractérisé en ce que le moyen d'obturation comprend un moyen d'actionnement comprenant un alliage à mémoire de forme (AMF) de sorte d'ouvrir le moyen d'obturation au-delà d'une température prédéfinie du capteur solaire thermique pour éviter sa surchauffe.
