ABSTRACT:
A tank holds a pool of liquid coolant in which spaced, rotatable disks are partially submerged. An air flow is established over exposed portions of the disks, preferably parallel thereto, whereby coolant adhering to the disks upon rotating out of the coolant pool is partially evaporated and the disks and remaining adhering coolant have their temperature lowered and serve to cool the coolant pool upon reentry into the pool from the air space above. A fluid to be cooled is passed through tubes mounted in the tank, below the surface of the liquid coolant, parallel to the surfaces of the disks. Adjacent rows of tubes define spaces therebetween, each of which receives the submerged portion of at least one disk. The evaporative cooler may be used in a refrigeration apparatus in combination with a compressor and an evaporator.
