Abstract
The collector comprises two thin stamped metal sheets, joined together by welding at their periphery, between which flows a heat-carrying liquid and is characterized in that said metal sheets are stamped with repetitive patterns whose concave surfaces are disposed opposite each other, but with staggering in their plane equal to approximately half a pitch, and in that the flat unstamped parts of said metal sheets are joined together by spot welds disposed substantially symmetrically and evenly in relation to said patterns. This collector is capable of resisting high pressures of the heat-carrying liquid.
