Solar collector

A solar collector comprising:

• a rectangular bottom,
• a rectangular frame, wherein the frame
• substantially corresponds in shape and is connected to the bottom and extends in a first direction therefrom,
• includes four wall sections,
• includes four corner sections,
• wherein each corner section extends between two immediately adjacent wall sections and terminates in the first direction away from the bottom at a corner section end,
• an outer rectangular glass pane, wherein the outer rectangular glass pane
• is in operative attached connection with the frame,
• extends substantially parallel to the bottom,
• is disposed in the first direction from the bottom,
• wherein the bottom, the rectangular frame and the outer rectangular glass pane bound a box-shaped collector space,
• an inner rectangular glass pane, wherein the inner rectangular glass pane
• is disposed within the box-shaped collector space,
• is disposed in the first direction from the bottom and extends intermediate of the bottom and the outer rectangular glass pane,
• extends substantially parallel to the bottom,
• four spacers, wherein the four spacers are positioned within the box shaped collector space,
• wherein each spacer extends in the first direction between and is in connection with a respective peripheral area of each of the outer rectangular glass pane and the inner rectangular glass pane,
• wherein the four spacers and the outer rectangular glass pane and the inner rectangular glass pane bound and intermediate pane space,
• wherein at least one air vent opening extends through the spacers to the intermediate pane space,
• an absorber sheet, wherein the absorber sheet
• is disposed within the box shaped collector space,
• is disposed in the first direction from the bottom and is intermediate of the bottom and the inner rectangular glass pane,
• extends substantially parallel to the bottom,
• at least one riser, wherein the at least one riser
• extends in the box shaped collector space,
• is disposed in the first direction from the bottom and extends intermediate of the bottom and the absorber sheet,
• extends substantially parallel to the bottom,
• at least two ventilation caps,
• wherein each ventilation cap outwardly overlies a respective corner section end of the frame,
• wherein each ventilation cap includes
• a first section, wherein the first section extends substantially parallel to the bottom and in overlying relation of respective corner section end,
• a pair of second sections, wherein each second section is attached to and extends substantially perpendicular to the first section,
• wherein each second section extends substantially parallel to and in outward overlying relation of a respective immediately adjacent side wall section at the respective corner section,
• at least one air passage, wherein the at least one air passage extends intermediate of each respective second section and a respective underlying wall section from at least one air passage end opening that is open to outside the box shaped collector space and faces in an opposed direction of the first direction, and wherein the at least one air passage is in fluid connection with the box shaped collector space, the at least one air vent opening and the intermediate pane space,
• whereby at least one ventilation channel including the at least one air passage fluidly extends between outside the box shaped collector space and the intermediate pane space.
