The aluminum heat exchanger is composed of aluminum tubes for heat exchangers passing cooling water and cooling fins for heat dissipation.
Aluminum tubes for heat exchangers are generally extruded and drawn from 1000 and 3000 series aluminum alloys to play the role of heat dissipation and cooling.

The Aluminum inner-grooved tubes for heat exchanger are mainly used in household air conditioners, freezers, refrigerators, automotive air conditioner tubes, automotive solar energy, etc.
The aluminum finned tube process is a labor-intensive process. It adopts the form of a base tube covered with an aluminum tube. (The base tube can be carbon steel or stainless steel) is extruded by a machine to form fins. The base of the fins is closely attached to the outer wall of the tube. Together, the length is from 0.5 meters to 6 meters.
It meets the demand for the length of the steel-aluminum finned tube, thus solving the trouble of re-cutting caused by improper length during use.

Fins per pitch(Density) : 4-12
Fin segments: 12, 16, 24 fins or as per your design
Fin height: Max. 16.5mm
Fin thickness: 0.4mm average
Core tube material: Aluminum alloy (Core tube with extremely thin wall materials can be applied.)
Base tube OD: Max 2”(50.8mm)
Tube wall thickness: No Limit
Tube length: No limit
Accessories: Tube support box, clamp & spacer box
Packaging details:
(1) Steel frame case sealed by plywoods with each end-capped.
(2) Solid fumigated wooden box with each end-capped.
Aluminum finned tubes have the characteristics of tight combination, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, not easy to deform in long-term cold and hot conditions, and long working life.
Aluminum finned tubes are mainly used in air coolers and air heaters in petrochemical, electric power, papermaking, tobacco, building heating and other industries, and air heaters in spray drying systems for vegetable eggs and starch in the food industry.
The advantages and characteristics of aluminum finned tubes in application is that aluminum finned tubes are formed in parallel with aluminum alloy plates and aluminum tubes at one time.
