SHUNT CHANNEL TECHNOLOGY (patented)


Enlarge «

80 per cent of the performance of liquid coolers is determined by the quality and design of the copper cold plate. Common liquid coolers in the market use a “micro-fin” structure. It has been proven as an efficient way to dissipate the heat by the liquid coolant. But according to the fluid mechanical theory of the “Boundary Layer”, the micro-fin design still contains a certain performance restriction: When the coolant enters the micro-fin channels, a part of the liquid will form a continuously growing laminar flow layer on the metal fins. It will obstruct the passage through the fins and alloy the heat dissipation. To compensate this effect, the pump has to run faster and push more coolant into the water block.

In 2012, Enermax engineers have finally found a clue. They successfully improved the cold plate design by adding a shunt channel. At the right position, this shunt prevents the formation of the boundary layers. The coolant can absorb more heat and the cooler achieves a much better cooling performance. Apart from that, Enermax successfully enhances the liquid flow inside the cold plate: Without the “Boundary Layer” obstacle, the heated coolant gains space to leave the hot spot area much quicker. More cool liquid can be pushed through the fins.
