• F24S 10/10 the working fluids forming pools or ponds
• F24S 10/20 having circuits for two or more working fluids (with means for exchanging heat between two or more fluids F24S10/30)
• F24S 10/25 having two or more passages for the same working fluid layered in direction of solar-rays, e.g. having upper circulation channels connected with lower circulation channels
• F24S 10/30 with means for exchanging heat between two or more working fluids
• F24S 10/40 in absorbing elements surrounded by transparent enclosures, e.g. evacuated solar collectors
• F24S 10/50 the working fluids being conveyed between plates
• F24S 10/60 the working fluids trickling freely over absorbing elements
• F24S 10/70 the working fluids being conveyed through tubular absorbing conduits
• F24S 10/80 comprising porous material or permeable masses directly contacting the working fluids (for conveying liquefied working fluid from evaporator sections to condenser sections with capillary force F24S10/95)
• F24S 10/90 using internal thermosiphonic circulation
