Typical automotive air conditioning & engine cooling components
- Heater cores
- Air charge coolers/intercoolers
- Engine oil coolers
- Transmission oil coolers
- Brazing is a metal joining method which provides a permanent bond between the parts joined with the help of a brazing filler metal.
- The composition of the liner-alloy is such that its melting point is slightly below the melting range of the core alloy.
- Brazing material is going to be joined mainly with finstock (either unclad or clad) or tubes (either extruded or welded from rolled aluminium).
- Brazing is done at about 600 degrees Celsius.
- The cladding can be on one or both sides and comprises 2-17 % of the thickness on each side.
- In recent years, brazed aluminium heat exchangers have been increasingly introduced to the automotive industry. Examples include automotive radiators, condensers, evaporators, heat cores, oil coolers, transmission oil coolers, air charge coolers, and fuel-cooling systems.
