How Integrated Thermal Protection Technology Can Prevent Solid State Relay Failure in Industrial Systems

Rogelio Castaneda and Oscar Rivera

What do large industrial/commercial HVAC and refrigeration systems, heavy duty transportation, conveyor belts, assembly lines, medical, energy and other complex manufacturing systems all have in common? Motors. Big and expensive electrical motors that, if they overheat, can be damaged or even destroyed. Most large motor driven machinery requires a system attached to the motor’s power supply that will sense overheating and turn off the motor to prevent this damage. In many cases, this device is an electrical relay that turns power on and off. There are two main types of these relays – electro-mechanical (EMRs) and solid state (SSRs). Continue reading

The Key to Solving the Problem of Thermal Management

Chris Aldham, Product Manager at 6SigmaET

As competition within the fast-paced world of the electronics industry scales new heights, product designers and manufacturers have found themselves under increasing pressure to cut both cost and time-to-market (TTM). The rapid rate at which modern technology is evolving is pushing engineers to create complex designs within a limited timeframe, often driven by marketing-led lines. Continue reading

Five Common Misconceptions about Thermal Design

Chris Aldham, Product Manager

Small, powerful, compact devices have always been at the heart of the electronics industry. But, with the constant demand for shrinking devices comes increased power densities and a lot more heat being generated in ever-decreasing spaces. The smaller the devices get, the more heat-conscious engineers need to be. Continue reading

Fanless Thermal Solution Design Guide for IoT Applications

The internet of things (IoT) network of interconnected devices is driving an explosion of integrated-electronic components (IC) for embedded applications. Compute and wireless systems and sensors will be deployed at the IoT edge, where environmental considerations have challenging implications for thermal and mechanical design. In order to function reliably in harsh environments with extended operating ambient temperature ranges, electronics housings for IoT solutions that support low-power components with fan-less designs in sealed enclosures will be desirable. This paper is intended to be a practical guide for the thermal designer to quickly size and implement an optimized fanless thermal solution that is feasible for high volume manufacturing.

Cooling Towers Offer Water and Energy Savings as Part of Efficient Data Center Cooling Systems

Douglas Bougher and Kent Martens, P.E.
SPX Cooling Technologies, Inc.

The number of data centers in the United States continues to grow in response to the enormous amount of digital information stored and streamed. The massive computer power within these data centers generates heat, making efficient cooling a key building system requirement. Evaporative cooling towers are an integral part of many data center cooling systems. Continue reading

Using Thermal Simulation to Design a Better Outdoor Electronic Product

Electronic products operate in varied thermal environments. Their operation is challenged when the size of the housing is reduced and when the product is mounted in an open environment exposed to climatic conditions. Solar radiation increases the temperature difference of the product’s internal air from the ambient by 150 to 300 percent. Continue reading

2 oz, or Not 2 oz: That is the Question?

Dr Giles Humpston, Applications Manager
Cambridge Nanotherm 

A variation of this question vexed Prince Hamlet while the modern version unsettles many a LED PCB designer. It’s all about copper thickness. When designing a PCB for LEDs, what weight of copper should be specified? Continue reading
