van der Aa, H H.M.

There is provided a solar collector comprising a heat pipe having an evaporator section and a condenser section, together with an absorber plate thermally conductively connected to the evaporator section, one side of the absorber plate being provided with a layer for the selective absorption of incident solar heat. An evacuated transparent envelope encloses the absorber plate and the evaporator section. A part of the evaporator section is free of the absorber plate and is provided with a separate layer for the selective absorption of incident solar heat, such separate layer having the same heat absorption coefficient as but a higher heat emission coefficient than the layer on the absorber plate per unit of length of the evaporator section.
