ABSTRACT:
A fluid dynamic crossflow cooling tower has a tower body. In the upper portion of the tower body, there is a horizontally disposed injection tubular element which has a plural number of spaced nozzles disposed on the lateral side. Heated fluid is pumped into the injection tubular element and is ejected out through the nozzles and forms a continuous screen of high velocity liquid flow into a horizontal diffuser. Outside cooling air is drawn into the tower through the air inlet located the lower portion of the tower body. The cooling air then mixes with heated liquid in the diffuser to perform heat exchange process. The liquid and air mixture then pass through a mist eliminator which separates liquid from the air. The air is then discharged out of the tower body, liquid is cooled and falls into a water dispersing trough and then passes through a heat radiator for the second pass heat exchanging process, and finally drops into a water tray at the bottom of the tower body. This invention can be adapted for a small size one-way or a large size two-way type cooling tower.
