The heat transfer to determine the best cooling effect. This cooler adopts tubular, cooling area is large and cooling effect is better.

The number of copper tubes in this cooler is more than three times that of the thistle tube type kettle. The cooling area is calculated based on the surface of the copper tube, so the cooling area is sufficient.

Cooler material is best for dissipating heat. Made of pure red copper tube, the thermal conductivity is over 95%.
