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...]
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...]
Microcontrollers Offer Temperature Sensing Accuracy
Silicon Laboratories has introduced a new family of high-performance 8-bit microcontrollers featuring the company’s latest mixed-signal breakthrough, an integrated temperature sensor with best-in-class accuracy over an extended temperature range and without the need for calibration. It offers a mix of integrated high-performance analog peripherals and a particularly fast 8051 … [Read more...]
High Efficiency Thermoelectric Air Conditioners
TECA Corporation has introduced the AHP-4250 family of thermoelectric air conditioners. They have a cooling capacity of 3,600 BTU/HR. “Green Zone” styles have efficiencies approaching 100 percent. Both styles come standard with TECA’s eco-mode temperature control design which helps save energy by limiting the need for active cooling when it’s not needed. Like TECA’s other … [Read more...]
