Water-shedding ventilation panel for heat-dissipating electrical welding equipment housing, has facing rows of strips with curved cross sections

摘要

Two opposite rows of strips with generally convex and concave inner and outer cross sections respectively, face each other. Convex faces (131) of each row face outwards as frontal components (130). Their edges (133) are offset such that they make mutual and partial entry into the concave regions (132) of the opposite row.
