Abstract

PURPOSE: To improve the heat transfer coefficient and obtain a fin type heat exchanger of excellent performance by cutting a plurality of grooves in the surfce of each fin so that the air flowing between fins is made turbulent.
CONSTITUTION: A fin material 8 is fed to a fin machining press by material feed rollers 9 and 10. Providing cutting edges 9' and 10' to cut grooves 7' on the surfaces of the material feed rollers 9 and 10 permits the grooves 7' to be cut while feeding the material. Thereby, a fin type heat exchanger of excellent performance can be obtained with a simple apparatus as well as without increasing the number of the processes.
