The review article emphasizes a single technique: Spray cooling, which is essential in diverse fields from laser treatments to humidifiers. Thus, proving its significance in modern-day research by proving it to be a perfect alternate solution as a cooling technique. The article thoroughly details single and multi-phase cooling with detailed insight into its architectural aspect, classification, and design. The article further emphasizes modeling heat transfer dynamics with a few attempts from simulations. It highlights the general mechanism of heat exchange involving arguments from the droplet level, impacted by successive generations of droplets, and the evolving thermal footprint of a hot surface to visualize cooling. Furthermore, an attempt to list out the factors involved in spray cooling, such as the nozzle characteristics, surface texture, flow rate, and spraying combinations have been discussed in detail. The later parts of the paper deal with the fundamental challenges related to the conduction of electricity, power consumption, efficient packing, corrosion, flooding, and suitable suggestions to overcome the mentioned problems. In the final part, a new enhancement has been suggested by the authors, which could, in theory, be the subsequent developmental work in spray cooling. The paper also includes summary tables relevant to the heading concepts to enhance, deepen, and help in the thorough understanding of the concepts.
