Why using Copper and Aluminum Composited Fin Tube for Air Cooler?
As known to all, copper is great for heat transfer. And aluminum also very effective in heat transfer. When design the heat exchanger on cooling or heating, heat transfer is always the first to consider, and then the cost.
The extended aluminum fins are responsible for 65%~70 of the heat transfer for any fin tube coil, and the base tube is responsible for the 30%~35%. The combination of copper and aluminum offers the most effective heat transfer at the most efficient cost. This is why copper and aluminum composited fin tube is welcomed by many clients.
Manufacturing process
The base copper tube (copper grade can be C12200, C70600, C44300, CuNi70/30, CuNi 90/10) is inserted into the aluminum muff tube, through rolling process, the fins are extruded out of the aluminum sleeve. Then ends fin will strip off from tube at customized length, cleaning, blast blowing, drying and then package.
Why copper and aluminum composited fin tube is popular?
Although the composited fin tube can be with base material such as carbon steel, 304/316 stainless steel, 90/10 copper-nickel, as well as other various different fin materials, none of these are as efficient or economical as copper/aluminum composited fin tubes.
We can not only produce Copper and Aluminum Composited fin tube in extruded fin type, but also can do it in L Foot Tension Fin, Overlapped L Fin, KL Fin and Grooved G Fin. For all these fin type, the base tube can be with copper and fin material be aluminum.
