Abstract
A solar collector (26) includes: an outer tube (64) of circular cross-section, closed at one of its ends, an absorption layer (52) arranged inside the outer tube (64), for absorbing solar radiation (Rs), and a heat pipe (56) including a hot part (58) laid out inside the outer tube (64), a cold part (60) arranged outside the outer tube (64), and a reservoir (62) containing a heat pipe fluid (63) and extending over the hot part (58) and the cold part (60). The outer tube (64) is hermetically closed around the heat pipe (56) at the other of its ends, a vacuum being formed inside said outer tube (64). For the hot part (58) of the heat pipe (56), the reservoir (62) is applied at least locally against the absorption layer (52).
