De la chaleur est absorbée à partir d'une section à basse température (32b) au moyen de l'air de combustion aspiré vers une chambre de combustion (26) à travers un tuyau d'admission (33) de dissipateur thermique fixé à la section à basse température (32b) de l'élément de production d'énergie thermique. Lors de l'augmentation de la température de combustion à l'intérieur de la chambre de combustion, la vitesse d'écoulement et le débit de l'air extérieur coulant dans le tuyau d'admission (33) du dissipateur thermique augmentent en raison d'un effet d'appel d'air, et la capacité d'absorption de chaleur du côté basse température de l'élément de production d'énergie thermique augmente également. Même si la température de combustion augmente, la différence de température entre le côté haute température et le côté basse température de l'élément de production d'énergie thermique peut être maintenue, et une production suffisante d'énergie est possible.
