Koolance's Response to Hardware Labs "The Copper Radiator Myth"

[hwlabs]

The Koolance heat exchangers appear to be standard automotive condensers.

We would also like to thank Koolance for demonstrating that even under such ridiculous testing conditions, our PA Series radiator outperforms the HWLabs GT Stealth 240 radiator in both Hydraulic Resistance and Thermal Capacity.

Marci, you wouldn't' be doing cartwheels if you read this: http://www.koolance.com/technical/my...ab_results.pdf

How the PA radiators "outperform" the GT Stealth radiators aren't clear in their tests.

At 5 m/sec air velocity and 5 l/min liquid mass flow:
The Thermochill 120.2 dissipates 6.25 kW
The Black Ice GTS240 dissipates 6.13 kW
The Koolance Radiator dissipates 9.62 kW

But at 10 m/sec air velocity and 5 l/min liquid mass flow:
The Thermochill 120.2 dissipates 7.11 kW
The Black Ice GTS240 dissipates 7.14 kW
The Koolance Radiator dissipates 10.41 kW

And at 3 m/sec air velocity and 5 l/min liquid mass flow:
The Thermochill 120.2 dissipates 5.64 kW
The Black Ice GTS240 dissipates 5.67 kW
The Koolance Radiator dissipates 8.86 kW

The only thing it clearly shows is how much bigger the PA's are how inefficient it is for its size in relation for this wind tunnel application. It also indicates several working points that show very minimal differences between the GTS240 and the PA 120.2 switching favors among the two.

There are some things that remain unclear with how these tests were conducted. The air pressure drop figures in relation to the W dissipated are very incongruent to real world data. How can a radiator of practically exact same dimensions, having a significantly higher pressure drop characteristic, yield 50% more performance? It doesn't make sense.

Somehow I wonder why those test results aren't allowed to be published for legal or advertising or lawsuit, deed etc..?
