Support unit for e.g. planar radiator, has leakage opening running through flow through chamber or discharging into chamber, where opening has larger cross-sectional area than other opening arranged in outer circumference of support unit

摘要

The support unit (1) has a central flow through opening (1.1) formed to a flow through chamber. Leakage openings (1.2.1, 1.2.2) communicating with the flow through opening and/or flow through chamber are arranged in the circumference of the support unit. One of the leakage openings (1.2.1) running through the flow through chamber or discharging into the flow through chamber has a larger cross-sectional area with a uniform diameter than the other leakage opening (1.2.2) arranged in the outer circumference of the support unit.
