ABSTRACT:
A refrigerant tube for use in heat exchangers comprises a flat tube having parallel refrigerant passages in its interior and comprising upper and lower walls and a plurality of reinforcing walls connected between the upper and lower walls, the reinforcing walls extending longitudinally of the tube and spaced apart from one another by a predetermined distance. The reinforcing walls are each formed with a plurality of communication holes for causing the parallel refrigerant passages to communicate with one another therethrough. Each of the reinforcing walls is 10 to 40% in opening ratio which is the proportion of all the communication holes in the reinforcing wall to the reinforcing wall.
