A solar thermal collector for heating a fluid with absorbed solar thermal energy from solar radiations is provided. The solar thermal collector comprises an inlet configured to supply the fluid into the solar thermal collector, an outlet configured to evacuate the fluid from the solar thermal collector, and a solar absorber having an absorber plate and a base plate. The absorber plate has an absorber plate perimeter and an absorbing surface configured for absorbing the solar thermal energy from solar radiations. The base plate is connected to the absorber plate along the entire absorber plate perimeter so as to define a sealed cavity. The base plate and the absorber plate are connected at a plurality of contact points distributed so as to create an array of junctures across the sealed cavity, thereby allowing the fluid to circulate throughout the sealed cavity when flowing from the inlet to the outlet.
A solar thermal collector for heating a fluid with absorbed solar thermal energy from solar radiations, the solar thermal collector comprising:
The solar thermal collector according to claim 0, wherein the contact points are evenly distributed along the absorbing surface of the absorber plate.
The solar thermal collector according to claim 0, wherein the array of junctures defines a juncture density selected within a range between about 100 junctures/m2 and 300 junctures/m2.
A solar thermal collector according to claim 0, further comprising at least one absorbing protuberance mounted to the absorbing surface of the absorber plate.
A solar thermal collector according to claim 0, wherein each of the at least one absorbing protuberance consists of a longitudinal bar having an L-shaped cross-section and having a contact portion mounted on the absorber plate and projecting from the contact portion, the longitudinal bar extending outwardly from the absorber plate so as to offer an extended absorbing surface to solar radiations.
A solar thermal assembly comprising the solar thermal collector according to according to claim 0, and further comprises a heat-insulating casing enclosing the solar absorber, the heat-insulating casing having a cover made from an optically transparent material and spaced-apart from the absorber plate.
A solar thermal collector according to claim 0, wherein the inlet and the outlet are located at diagonally opposed corners of the base plate.
A solar thermal collector according to claim 0, wherein the inlet and the outlet are maximally spaced-apart.
