A facade element for heat-insulation purposes has at least two parallel panels (101, 102), a cavity (103), which is formed between these two panels (101, 102) and has fluid flowing through it, and at least one inlet (13), for feeding a radiation-absorbing fluid, and at least one outlet (13′), for di
A facade element for heat-insulation purposes has at least two parallel panels (101, 102), a cavity (103), which is formed between these two panels (101, 102) and has fluid flowing through it, and at least one inlet (13), for feeding a radiation-absorbing fluid, and at least one outlet (13′), for discharging the fluid. The inlet (13) is arranged on a first side of the panels (101, 102) and the outlet (13′) is arranged on an opposite, second side of the panels (101, 102). The at least one inlet (13) and the cavity (103) have arranged between them a first flow distributor (14), which extends for distribution along the length of the first side. This facade element makes straightforward and cost-effective industrial production possible.

1. A facade element for thermal insulation comprising: at least two panes arranged parallel to and at a distance from one another,a cavity which is formed between said at least two panes,at least one inlet for feeding a radiation-absorbing fluid into the cavity,at least one outlet for discharging the fluid from the cavity, anda first flow distributor arranged within the cavity,wherein the at least one inlet is arranged on a first side of the at least two panes and the at least one outlet is arranged on an opposite, second side of the at least two panes,wherein the first flow distributor is a strip that extends along the first side in an edge region of the at least two panes, between an inlet portion of the cavity and a remaining portion of the cavity, the strip filling the distance between the at least two panes such that the strip contacts the at least two panes, the strip having a longitudinal direction and the strip defining a plurality of passages, each passage connecting the inlet portion and the remaining portion of the cavity, the strip thereby sealingly separating the inlet portion from the remaining portion except for the passages,the strip having elevations, which are arranged at a distance from one another along the strip to form spacings between the elevations, the passages being formed by said spacings, the passages thereby extending in a direction perpendicular to the longitudinal direction of the strip. 2. The facade element as claimed in claim 1, wherein the passages form nozzles. 3. The facade element as claimed in claim 2, wherein each nozzle has, in a flow direction, an inlet opening, the inlet opening narrowing along the flow direction and having a first opening angle in a plane defined by said at least two panes, the inlet opening defining an inlet path, and wherein each nozzle has, downstream from said inlet opening, an outlet opening, the outlet opening widening along the flow direction and having a second opening angle in said plane, the outlet opening defining an outlet path, wherein the first opening angle is greater than the second opening angle and the inlet path is shorter than the outlet path. 4. The facade element as claimed in claim 1, wherein the elevations have a droplet shape when viewed in a plane defined by the at least two panes. 5. The facade element as claimed in claim 1, wherein the strip is produced from plastic or from a metal. 6. The facade element as claimed in claim 1, wherein a plurality of inlets are present which are arranged in a distributed manner along the first side of the at least two panes. 7. The facade element as claimed in claim 1, wherein the first side is the lowermost side of the facade element in its vertical use position. 8. The facade element as claimed in claim 1, wherein a second flow distributor is arranged in the cavity upstream of the at least one outlet. 9. The facade element as claimed in claim 8, wherein the second flow distributor is designed identically to the first flow distributor and is oriented identically or in a mirror-inverted manner. 10. The facade element as claimed in claim 1, wherein a plurality of outlets are provided which are arranged in a distributed manner over the second side. 11. A facade element for thermal insulation comprising: at least two panes arranged parallel to and at a distance from one another,a cavity which is formed between said at least two panes,at least one inlet for feeding a radiation-absorbing fluid into the cavity,at least one outlet for discharging the fluid from the cavity, anda first flow distributor arranged within the cavity,wherein the at least one inlet is arranged on a first side of the at least two panes and the at least one outlet is arranged on an opposite, second side of the at least two panes,wherein the first flow distributor extends along the first side in an edge region of the at least two panes, between an inlet portion of the cavity and a remaining portion of the cavity, the first flow distributor filling the distance between the at least two panes such that the first flow distributor contacts the at least two panes, the first flow distributor defining a plurality of passages, each passage connecting the inlet portion and the remaining portion of the cavity, the first flow distributor thereby sealingly separating the inlet portion from the remaining portion except for the passages,the passages forming nozzles, each nozzle having, in a flow direction, an inlet opening, the inlet opening narrowing along the flow direction and having a first opening angle in a plane defined by said at least two panes, the inlet opening defining an inlet path, and each nozzle having, downstream from said inlet opening, an outlet opening, the outlet opening widening along the flow direction and having a second opening angle in said plane, the outlet opening defining an outlet path, andwherein the first opening angle is greater than the second opening angle and the inlet path is shorter than the outlet path. 12. The façade element according to claim 1 wherein the at least two panes are transparent. 13. The façade element according to claim 1 wherein the façade element is permeable to visible light. 14. The façade element according to claim 1 wherein the façade element is a window.
