This invention provides a small-scale seawater desalination device based on the Miura folding method and the solar chimney effect, comprising a seawater evaporation chamber, a heat collection shed, a chimney, and a condensate collection system. The heat collection shed is fixedly installed above the seawater evaporation chamber and covers the opening on the upper surface of the chamber. The heat collection shed is a flat plate structure with folds formed by the Miura folding method, and several Fresnel lenses are adhered to it. A ring-shaped chimney water collection trough is installed at the bottom of the chimney. The chimney is a tubular structure with folds formed by the Miura folding method. The condensate collection system includes a water collection hood and an auxiliary collection pipe. The water collection hood is installed at the top of the chimney and includes a shell, a fine condensate mesh, and a ring-shaped water collection trough. The auxiliary collection pipe connects to a drain hole on the chimney water collection trough. This invention improves solar thermal efficiency, seawater evaporation rate, and water vapor guiding efficiency.
