Charge Air Coolers for Heavy-Duty Trucks

Added Strength for Severe Operating Conditions

Formed tanks are used on a majority of Griffin thermal transfer products. Formed tanks eliminate the need to weld edges or right angles. The only welding required is at the tank to header area. This area is reinforced by a header design that is equivalent to the same material thickness as the tank. The additional tank to header thickness provides added strength for severe operating conditions.

Where formed tanks are not possible, Griffin uses an extruded u-shaped tank. The extruded tank provides design flexibility for medium to large capacity products. Extruded tanks also allow for increased operating pressures.

The Difference

For normal to heavy duty operating conditions, Griffin uses high frequency welded tubes. In typical aluminum radiators for OEM and industrial applications, a water tube thickness of 0.32mm and a fin thickness of 0.08mm is used. Griffin uses a water tube thickness of 0.40mm and a fin thickness of 0.127mm. Increased water tube and fin thickness provides additional strength and enhances heat transfer characteristics.
