difficult

1. After the project has been completed, it can establish the domestic productive capacity of aluminum curved heat exchangers, and the government tax is increased substantially.
2. Promote the domestic aluminum material processing technology , and integrate technology platform for industry, government and academia.


3.
(1.)Industry imports brazing and bending machine, developing pure aluminum tube composition design and evaluating fins and brazing process, overcome with the problems of welding stress concentration and spread corrosion.
(2.)Mobility test used by aluminum fins thereby effectively inhibit the weld zone segregation behavior and stress problems.
90 degrees to facilitate the back-bending, and adjusting processing conditions, making the flat tube and weld with good workability.Less susceptible to the effect of pulling tension caused by flat pipe rupture.



4.

(1)The new products made by bending process can more big area and raise rate of heat transfer, can satisfied product market.
(2)Industry in Taiwan can make aluminum technology better, expect102 103 years to raise the business volume one hundred million and three hundred million
