A solar collector plate (1) comprises a dark-coloured absorber plate (2) facing the sun, parallel wall sheets (4) arranged perpendicularly to the rear side of the absorber sheet (2), fixed thereto and also fixed to a support sheet (3) arranged parallel to the absorber sheet (2), whereby cavity channels (5) are provided between said sheets (2, 3, 4) for flowing cooling liquid (6) which is intended to transport heat away from the absorber sheet (2). In order to provide a good thermal contact between the liquid (6) and the absorber sheet (2) at a low rate of liquid flow in the cavity channels, the cavity channels (5) are filled with particles (7), which particles lift the cooling liquid (6) to contact with the absorber sheet (2) by means of a capillary effect.
Le panneau capteur solaire (1) de la présente invention est constitué d'un panneau absorbant (2) de couleur sombre tourné vers le soleil, de panneaux fins parallèles (4) disposés perpendiculairement à la face arrière du panneau absorbant (2), lesquels panneaux fins sont fixés audit panneau absorbant et à un panneau support (3) parallèle au panneau absorbant. Cet agencement forme des canaux creux (5) entre lesdits panneaux (2, 3, 4) dans lesquels circule un liquide de refroidissement (6) prévu pour évacuer la chaleur du panneau absorbant (2). Pour assurer un bon contact thermique entre le liquide (6) et le panneau absorbant (2) malgré un faible débit d'écoulement du liquide dans les canaux creux, lesdits canaux creux (5) sont remplis de particules (7) qui font attirent par capillarité le liquide de refroidissement (6) au contact du panneau absorbant (2).
