Ceramtec’s CeramCool Box is made for homogeneous and efficient cooling of packing densities up to 100W/cm2. For example, with an edge length of just 16 x 40 x 40 mm it has a total cooling capacity of 1600W, which corresponds to a thermal capacity of 1200W. The maximum temperature of an LED is just 90°C with a coolant flow rate of 180l/h and an ambient and cooling water … [Read more...]
Diamond-Thin Films Cool Electronics
Two new studies performed at the U.S. Department of Energy’s Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films. The unusually attractive thermal properties of diamond thin films have led scientists to suggest using this material as a heat sink that could be integrated … [Read more...]

SEMI-THERM is pleased to announce Alfonso Ortega, Ph.D. as the recipient for the Harvey Rosten Award for his paper "An Investigation of Multi-Layer Mini-Channel Heat Sinks with Channel Geometric Sponsored by Mentor Graphics, Mechanical Analysis Division." Dr. Al Ortega is the James R. Birle Professor of Energy Technology at Villanova University and the Director of the … [Read more...]
Enhancement of Microchannel Cooling with Oblique Technology
Microchannel cooling has emerged as an effective method to enhance cooling for electronics devices [1]. However, the problem of boundary layer development, as liquid coolant travels downstream, persists in conventional microchannel heatsinks. Consequently, convective heat transfer performance of a heat sink deteriorates in the axial direction, resulting in elevated maximum … [Read more...]
Apple to Recreate Ionic Wind Generator Cooling System
The U.S. Patent & Trademark Office has published a patent application that reveals Apple’s intent to reinvent the ionic wind generator. The traditional ionic wind generator design is only effective at cooling limited areas of an electronic device and distributes air throughout the device evenly, without thought to what portions of the device are in use. According to the … [Read more...]
