Sandia's new design offers a breakthrough in refrigeration technology

Sandia National Laboratories has developed a new technology with the potential to completely revolutionize the field of cooling air in the computer world. They are currently in the process of registering the product license to start marketing it. The "Watermelon Cooler" is also known as "Air Bearing Heat Exchanger," or translated, "the heat exchanger orientation of the air." This is a totally new product, invented and developed by Sandia researcher Jeff Koplow.

In a conventional CPU cooler, bottlenecks are formed in the transfer of heat by the "dead air" that falls between the aluminum fins. With Sandia Cooler, heat is transferred efficiently through a narrow air gap from a fixed base to a rotating structure. Thanks to a powerful centrifugal pump, these blades spin, making its thickness is reduced 10 times compared to normal.

This reduction allows a huge improvement in cooling capacity with a size much smaller. Additionally, the high speed of rotation of the heat exchanger plates minimizes the problem of dirt in the sink. Also, the way they have been redesigned aluminum blades make the air flow through them more efficiently, resulting in a much quieter operation.

Cooler Sandia These benefits have been thoroughly tested by scientists using the first prototype, approximately the same size as that of a CPU cooler. Basically, the Sandia Cooler is a copper base that makes direct contact with the processor, with a central rotor that spins the aluminum fins (so it has no fan) and the heat transferred from the base of these copper is efficiently dissipated, and they are the ones that are spinning, not a fan.
