INTRODUCTION A Thermal Load Board (TLB) is a hardware tool used to simulate an actual application board, for example - computer motherboard, blade server board, handheld device main logic board, etc. Mounted on the TLB are a variety of heat source simulators that allow heat flux generation in a manner that closely approximates real semiconductor devices and other components … [Read more...]
New High-Efficiency Thermoelectric Air Conditioner
TECA Corporation has introduced the AHP-6200 family of thermoelectric air conditioners. The AHP-6200 air conditioners provide cooling performance up to 5,200 BTU/hr in the 240 VAC configurations. Each system includes TECA’s Eco-Mode temperature control design that limits active cooling when not needed, reducing total power consumption by up to 75 percent. The AHP-6200 air … [Read more...]
Semiconductors Grown on Graphene May Change Industry
CrayoNano AS, in cooperation with the Norwegian University of Science and Technology (NTNU), has introduced GaAs nanowires grown on graphene, a patented hybrid material with competitive properties. The patented method of growing semiconductor nanowires on atomically thin graphene uses MBE (Molecular Beam Epitaxy) to grow the nanowires and offers excellent optoelectronic … [Read more...]
Single Electron Diode May Control Heat Flow in Tiny Future Electronics
As the scale of electronic devices and their components continues to shrink, researchers at Aalto University in Finland are re-examining options for fine-tuning control of the heat generated by electronic components. Doctoral student Tomi Ruokola, in cooperation with researcher Teemu Ojanen of O.V. Lounasmaa Laboratory, has developed a single-electron diode that allows heat to … [Read more...]
Characteristic Length and the Cooling Circle
Introduction One of the most baffling things in cooling for the novice mechanical engineer is the fact that with the exact same geometries and dimensions, thermal solutions just do not perform the same. Past results do not guarantee future performance, and doubling the surface area of a tried and tested design to double the cooling capacity, as per Newton’s cooling law, does … [Read more...]
