| 摘要 |
The invention relates to a solar collector, comprising a rectangular bottom (10), a frame (12), an outer, rectangular glass pane (14) and an inner, rectangular glass pane (16), wherein said distance between inner and outer glass panes (16, 14) is defined by spacers (18), an absorber sheet (20) and at least one riser (22) wherein said bottom (10), said frame (12) and said outer glass pane (14) define a box-shaped collector space (KR), and the bottom (10), the outer glass pane (14), the inner glass pane (16), the absorber sheet (20) and the risers (22) extend predominantly parallel to each other, as well as at least two ventilation caps (30) arranged at a distance to each other, and each cap comprising: a first section (32), abutting with an inner side (32I) against an outer side (32A) of the frame (12) at the upper end (12E) of said frame (12), a second section (34), extending orthogonally to the first section (32), overlapping with an inner side (34I) a terminal upper front face (12S) of the frame (12), wherein the inner sides (32I, 34I) of both first and second sections (32, 34) each display a pattern (32P, 34P, 34Z), providing at least one continuous ventilation channel (BK) along said inner sides (32L, 34L), which ventilation channel (BK) leads from an outside into said collector space (KR), and said ventilation channel (BK) is fluidly connected via at least one opening (24) in said spacers (18) to said space (R) between the inner and outer glass panes (16, 14). |
