Product Description

The demands made by the manufacturers of motor vehicles on the suppliers of engine cooling systems is such that there is an ever-increasing pressure to reduce unit size and increase utility of the radiator in an increasingly difficult environment for heat transfer. This has led to the development of high efficiency, secondary surfaces on the air side with the adoption of designs that are more common in the aerospace sector.

When dimpling is applied to a radiator core, the improvement is brought about as a result of changing the heat transfer characteristics of the air side primary surface.

A further consideration to a system that uses a HF welded, dimpled tube, is that it will have a much larger pressure drop than one with a plain tube and will therefore, require more pumping power to achieve the same water flow rates.

Details and results from an experimental facility, designed to measure and compare the heat transfer characteristics of a plain and dimpled radiator core tube, are available to download from our website.
