ABSTRACT:
A fin and refrigerant tube assembly is mounted in a housing. The fins are arranged parallel to each other and the tube is doubled back on itself a number of times to perpendicularly extend through and be connected to the fins at a plurality of locations. The doubled over U-shaped ends of the tube extend external of the ends of the fin assembly. Air is forced from a main inlet through the fins parallel thereto to an outlet. The housing in conjunction with one end of the fin assembly defines a precooling chamber having a secondary air inlet and an outlet leading to the main inlet. Air passing through the precooling chamber is cooled by the doubled over ends of the tube and moisture condenses on the doubled over ends of the tube. Dust particles entrained in the air accumulate with the moisture on the doubled over ends of the tube rather than on fins whereby the spaces between the fins do not become clogged with dust.
