Abstract
A heat exchanger includes parallel flat fins spaced apart to conduct an air current therebetween. Heat transfer pipes for conducting refrigerant pass perpendicularly through the fins in a zigzag pattern. Each fin includes grilles in the form of slits which are oriented generally radially relative to respective heat transfer pipes for disturbing the air current passing around the outer peripheries of the pipes. Ridges are formed in each fin in front of and behind each pipe to increase the heat transfer area to increase the heat transfer area of the fin and strengthen the fin against bending forces.
