Water cooling by ambient takes place with two mechanisms of heat and mass transfer. Using packings at wet cooling towers has disadvantages such as obstruction, reduction of life expectancy and production of algae and fungi. In shower cooling towers types of towers packings are completely removed and water intake is in direct contact and heat transfer takes place in two ways of latent and sensible. In this article mathematical modeling and simulation of towers has been done using differential equations. Differential equations derived using the laws of conservation of mass and energy.  Differential equations is solved in a computer program for numerical solution. The operation of shower cooling towers at different environmental conditions was observed. These towers in the area of cold, dry, warm and dry possess high efficiency. In very hot areas by reducing the drops diameter, the tower outlet temperature can be improved.
