Abstract:
A method for manufacturing a radiator with thin fins, comprising the steps of:a. forming thin fins by punching metal sheets with dies so that a plurality of first through holes are formed near a lower end of said thin fins, said metal sheets having a high coefficient of heat transmission; b. forming spacers by punching metal sheets with dies so that a plurality of second through holes are formed near a lower end of said spacers at positions corresponding to said first through holes, said spacers being elongated plates having a height smaller than that of said thin fins, and said spacers having a thickness larger than that of said thin fins, said metal sheets having a high coefficient of heat transmission; c. assembling said thin fins and said spacers by spacing said thin fins alternately with said spacers and aligning said first through holes with said second through holes, and sequentially extending rivets through said aligned first and second through holes to fix said thin fins and said spacers together to provide a preform of said radiator; and d. grinding an uneven bottom of said preform of said radiator to remove any unevenness so that a finished product of said radiator is provided.
