Fanless cooling of more and more efficient systems requires powerful heatsinks having a extremely large surface. To cool these systems efficiently, EKL AG offers coolers coming from a cold forging procedure. Using high purity aluminum and copper in the shape of pin coolers meets these requirements in an optimum way. In contrast to extruded coolers more complex geometries can be manufactured as well. Apart from customized design EKL AG also offers a selection of standard dimensions.
