The use of epoxy in
Griffin Radiators is to strengthen the tube to header
brazed joints, has been used for many years by the
automotive and truck radiator manufacturers.
Designed by BF Goodrich for Ford Motor Co. and tested
over 1 million miles on cross country Class A Trucks,
the epoxy application was proven to give longer
life to the radiator core.
The addition of epoxy at the tube to header joints,
allows additional surface area, resulting in a stronger
tube to header joint when compared to aluminum brazed
radiators without the use of epoxy. |
The Griffin Thermal
Products aluminum radiators use aluminum formed
tanks, which eliminates the need to tig weld the
edges reducing fatigue failures from vibration.
Formed tanks allow the air at high speeds to flow
more uniformly, reducing drag. The ribs in the tank
provide strength and prevent aeration of the water,
which causes cavitation in the water pump, and creates
heat and reduces horsepower.
The aluminum formed tank also eliminates the need
for welding at the right angle joints. The only
welding required is at the tank to header area.
The weld joints within the tank to header area are
reinforced by the header design that is equivalent
to the same material thickness as the tank. Therefore,
the actual tank to header weld joint is approximately
two x's the thickness of the tank. This additional
tank to header thickness reinforces the needed strength
for higher pressure conditions. |
The typical Griffin
OEM aluminum brazed radiator uses a water tube thickness
of 0.32mm and fin thickness of 0.08mm.
This aluminum radiator uses a water tube thickness
of 0.40mm and a fin thickness of 0.127mm. These
additional material thicknesses' used within the
water tube and fin, allow for additional strength
within the radiator for longer life and reliability.
In addition, the added material thickness within
the water tube and fin, enhances the transfer characteristics
within the Griffin Thermal Products aluminum radiators,
when compared to many aluminum radiators that are
available by the use of the typical aluminum radiator
cores manufactured for the passenger car and light
truck applications. |
