  • the tube runs within a transparent vacuum tube, which surrounds the tube like a jacket and largely protects against heat losses by heat conduction. Inside the tube is a liquid which also heats up and evaporates when the tube is heated.

Abstract

L'invention concerne un capteur solaire comprenant un tube échangeur de chaleur, à savoir un caloduc ou un thermosiphon à deux phases, présentant un condenseur. Ce condenseur peut transférer de la chaleur par conduction thermique à un liquide à chaleur utile circulant autour du condenseur à l'intérieur d'un canal d'écoulement et s'écoulant vers l'extérieur du capteur solaire. Le condenseur se trouve en contact mécanique direct avec le liquide à chaleur utile de sorte qu'aucune matière solide ne se trouve entre le condenseur et le liquide à chaleur utile et que le liquide à chaleur utile circule ainsi directement autour du condenseur, ce qui permet d'accroître le rendement du capteur solaire.
