Calculation Corner: Thermal Interactions Between High-Power Packages and Heat Sinks, Part 1
Bruce Guenin, PhD Associate Technical Editor The need to accommodate increasing chip power has led to improved package and heat sink designs having much lower thermal resistance values than previously. This has led to challenges in accurately calculating the thermal performance of the package and heat sink as an integral unit on the basis of thermal resistance measurements … [Read more...]
SynJet Technology Helps Europe Go Green
Nuventix, Inc. announced it is seeing significant adoption of its SynJet technology across Europe, most notably in store installations of the region’s largest retailer. SynJet LED coolers maximize lumen output and extend the life of LEDs in the stores of Carrefour’s new hypermarket concept, Planet Carrefour. By delivering targeted pulses of air directly to the LED system's heat … [Read more...]
Analysis System Ensures Optimal Heat Sink Efficiency
The new Tactilus® heat-sink analysis system by Sensor Products Inc. enables research and design engineers to quickly and precisely test and correct the surface contact and pressure distribution between the heat sink and semiconductor. With Tactilus, engineers can visualize actual contact forces and pressure distribution data on the circuit board components. As the mounting … [Read more...]
High Power Drives Raise Standards for Heat Management
Danfoss has expanded its range of VLT drives with power capabilities up to 1.2MW. Drive voltage ratings range from 380VAC through 690VAC. A back-channel cooling method solves the heat loss problem by exhausting the majority of the cooling air and 85 percent of the heat loss to the outside of the control room. Furthermore, this cooling air only passes over heat sink surfaces and … [Read more...]
