“…Roll-bond technology is already widely used in the manufacturing of heat exchangers, such as evaporators for domestic refrigeration or radiant panels. It has also been investigated in various studies on solar thermal application (Anon, 1984;Joshi, 1986;Hufnagel, 1976;Orlando et al, 1979;Tekkaya et al, 2012) and in the recent past roll-bond exchanger are being introduced in PVT collectors (Boddaert and Caccavelli, 2006), due to the recent technological improvements which allow the PV lamination on the absorber plate (Dupeyrat et al, 2009;Dupeyrat et al, 2011a).…”
