Abstract: Implementing a neoteric practical design for dew-point evaporative cooler (DPEC) rather than the widely used flat plate and corrugated plate types has been challenging since its first invention. Thus far, no study has been dedicated to design and experimentally implement a shell and tube concept for DPEC with an innovative configuration that can contribute to mass production, globalization, and effortless maintenance of such a high-performance cooling machine. Therefore, in this paper, the shell and tube concept has been employed as a core design for DPEC that has been reinforced by practical approaches. The practical approaches include a dedicated novel design for the proposed system and utilizing super cheap materials for the system's construction. Both of the aforementioned approaches provide solutions for overcoming the aforementioned issues. In the meanwhile, the superiority of the proposed DPEC has been approved by comparing it to the flat plate DPEC. During the experimentations, the prototype was able to reduce the ambient temperature by up to 34.1 °C (from 53 °C to 18.9 °C), besides, it could achieve a dew-point effectiveness of 99.6 % and wet-bulb effectiveness of 135 %.
