Ultra-precision aluminum extrusion technology for high-performance heat exchangers
Flat multi-hole aluminum tubes with multiple tiny holes offer improved heat exchange performance and are used in automotive air conditioners and outdoor units of room air conditioners.
- Can also be manufactured using 3000 series alloys for high pressureCO2refrigerant applications.
- By having several inner ribs in its cross section, these tubes can withstand multiple bending processing in the longitudinal direction,keeping passages for refrigerant and cooling water unobstructed.
- In recent years, these tubes are also being used more to provide a cooling system for EV and FCV batteries.
Features
- Use of type 1000 alloy, which has good heat conductivity, with many tiny holes, delivers excellent heat transfer performance.
- Cross section offers a high degree of freedom in terms of design, so the tiny holes can be square, round, or rib shaped, realizing a much narrower tolerance range among extruded materials.
- The surface of the multi-hole tube can be sprayed with zinc or coated with flux to improve corrosion resistance.
