FRESH-CART Portable Solar Evaporative Cooling Cart

Create a professional engineering CAD model of FRESH-CART, a portable solar-powered evaporative cooling cart for fruits and vegetables. Overall design: A compact rectangular mobile cart mounted on four wheels, with a lightweight wooden/metal frame and an insulated produce-storage chamber. Main dimensions: approximately 1500 mm long × 1000 mm wide × 1200 mm high for the storage chamber. Keep the design proportional and suitable for a small farmer/vendor. Key Components 1. Insulated Produce Chamber – central enclosed chamber with shelves for fruits and vegetables. 2. Jute–Luffa Evaporative Cooling Pad – clearly visible on one side of the chamber as the main cooling component. Show the porous natural-fiber pad in a removable frame. 3. Covered Terracotta Water Tank – positioned below/next to the cooling pad, with a clearly visible lid/cover. 4. Water Pump – connected to the terracotta tank. 5. Perforated Water Distribution Pipe – placed above the jute–luffa pad to distribute water uniformly. 6. DC Fan – positioned behind the cooling pad to draw hot ambient air through the wet pad. 7. Solar Panel – mounted on the roof of the cart. 8. Battery and electrical compartment – placed safely inside the lower section. 9. Chimney/Exhaust Vent – mounted on the top of the produce chamber to discharge warm air. 10. Four wheels – strong enough for mobility on local roads. Airflow Show red arrows for hot ambient air entering through the wet jute–luffa pad, blue arrows for cooled air entering and circulating through the produce chamber, and red/orange arrows for warm air leaving through the chimney. CAD Presentation Create a clean engineering-style 3D CAD model with a sectional/cutaway view so the internal components are visible. Add clear labels for all major components, dimensions, airflow arrows, and water-flow arrows. Use a professional mechanical-design appearance with realistic component placement, suitable for a college engineering project presentation and technical poster. Important: The **jute–luffa evaporative cooling pad must be visually prominent and clearly identified as the primary cooling mechanism. Do not replace it with a conventional cooling coil or refrigeration unit. The terracotta component must be a covered water tank, not a terracotta chimney.
