Abstract
Abstract A solar heat absorber including a heat exchanger panel having a first surface and a second surface, the first surface having a grid-like pattern of upstanding intersecting walls with at least one of the walls being of a height which is greater than the other walls. The wall of greater height reaches substantially to the cover of the heat absorber so as to restrain air currents near the cover. The second surface includes a number of parallel spaced-apart walls defining passageways along which air can flow.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
186 words
A solar heat absorber comprising: a housing having a translucent cover; a heat exchanger panel located within said housing; inlet and outlet duct means coupled to said housing, whereby air can respectively enter and leave said housing, said heat exchanger panel having a first surface which faces said cover and a second surface on the opposite side thereof, said first surface having a grid-like pattern of upstanding intersecting walls with at least one of said walls being of a height which is greater than the other walls, said wall of greater height reaching substantially to the said translucent cover so as to restrain air currents near the said cover, and said second surface having a number of parallel spaced-apart walls extending therefrom, said heat exchanger panel being separated from the walls of said housing by insulating material, the walls extending from the second surface defining passageways along which air entering into said housing from said inlet duct means can flow to said outlet duct means and in the process be heated by heat absorbed by the first surface from solar radiation and transferred through said panel.
Claim 2
Dependent Claim
186 words
A solar heat absorber comprising: a housing having a translucent cover; a heat exchanger panel located within said housing; inlet and outlet duct means coupled to said housing, whereby air can respectively enter and leave said housing, said heat exchanger panel having a first surface which faces said cover and a second surface on the opposite side thereof, said first surface having a grid-like pattern of upstanding intersecting walls with at least one of said walls being of a height which is greater than the other walls, said wall of greater height reaching substantially to the said translucent cover so as to restrain air currents near the said cover, and said second surface having a number of parallel spaced-apart walls extending therefrom, said heat exchanger panel being separated from the walls of said housing by insulating material, the walls extending from the second surface defining passageways along which air entering into said housing from said inlet duct means can flow to said outlet duct means and in the process be heated by heat absorbed by the first surface from solar radiation and transferred through said panel.
