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 1050, 1100, 3003, 5083, 6061, 6063 aluminum tube to play the role of heat dissipation and cooling.
The choice of alloy depends on factors such as the specific application, operating conditions and required properties such as strength, corrosion resistance and thermal conductivity.Quick Quote
Aluminium finned tube for heat exchanger
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.

Aluminum flat tube for heat exchangers
Aluminum brazed heat exchangers are widely used in automotive air conditioning systems. Typically, such heat exchangers are made from flat tubes with multiple independent channels in cross-section, forming a serpentine or parallel flow geometry.
In these heat exchangers, multiple louvered corrugated fins are inserted into the gaps between flat tubes. Due to their high performance, some companies are beginning to use extruded brazed aluminum heat exchangers in heating, ventilation and air conditioning applications.Quick Quote
