Outdoor rental screen cabinets are protective enclosures that house LED panels, power supplies, and driver boards—designed to balance durability, portability, and heat dissipation for temporary outdoor use. Unlike fixed outdoor screen enclosures (which are heavy and permanent), rental cabinets prioritize lightweight materials and easy access to components (for quick maintenance or panel replacement).

Key design features include: 1) Material Selection: Cabinets are made of 1.5-2mm thick aluminum alloy (weight: 3-5kg per cabinet) to reduce overall load while resisting corrosion (critical for coastal events with salt spray). Some models use reinforced plastic (ABS) for even lighter weight (2-3kg per cabinet), suitable for small-scale events like pop-up shops. 2) Waterproof & Dustproof Design: Cabinets meet IP65 or IP67 ratings—seams are sealed with EPDM rubber gaskets, and ventilation holes have dust filters to prevent debris from entering. The back panel has a hinged door (with a waterproof latch) for easy access to internal components (no need to remove the entire cabinet for repairs). 3) Heat Dissipation: Built-in axial fans (2-4 per cabinet) or passive heat sinks draw hot air out of the cabinet—critical for outdoor use, as internal temperatures can rise to 50°C in direct sun. Fans are temperature-controlled (activate at 35°C) to save energy and reduce noise (fan noise <40dB, unnoticeable at events). 4) Compatibility: Cabinets are standardized to fit common panel sizes (500x500mm or 500x1000mm) and have universal mounting points (compatible with most truss systems). They also include cable management channels to route power and signal cables neatly, reducing tripping hazards.

A rental company noted that aluminum cabinets had a 95% reuse rate over 3 years, with minimal damage from transportation (thanks to reinforced corners). For large events, cabinets can be stacked horizontally or vertically (up to 10 cabinets high) to form custom screen sizes—each cabinet has alignment guides to ensure stable stacking.
