In order to fit the request of different market, we designed a particular structure of aluminum fin/copper tube structure for your choice. Our structure has the following advantages:
<1> The aluminum fin is made by one fin but not two,thus avoid the stress on the copper from mechanical compress.
<2> The structure is good to avoid any possible electrolytic corrosion between aluminium/copper ( if ultrasonic welding between two material,this problem will happen)
<3> This structure is stronger between aluminum/ copper connection
<4> Better at heat absorption, since :
.thicker aluminum fin
.there is wrinkle on aluminum fin
.there is more contact surface between the aluminum/copper.
