Laird Thermal Systems has introduced a series of thermoelectric assemblies (TEAs) designed for use in outdoor environments. The Outdoor Cooler Series are compact (cooling objects via convection) air-to-air TEAs said to provide a lower total cost of ownership by maintaining the appropriate temperature range using minimal energy due to its high coefficient of performance … [Read more...]
Using Wide Bandgap Materials in Power Electronics Presents a New Set of Thermal Challenges
The power electronics industry has reached the theoretical limits of silicon and now is moving to other semiconductor materials whose performance meets the requirements of today’s high power density systems. A number of techniques are being used to overcome the thermal limitations of power modules. One approach is using semiconductor materials which are able to bypass Si’s … [Read more...]
ACT Acquires Parker Hannifin’s Precision Cooling Business
Advanced Cooling Technologies, Inc. (“ACT”), a premier thermal management solutions company, announced today that it has completed the acquisition of Parker Hannifin Corporation’s Precision Cooling Business (“PCB”), a leading supplier of Pumped Two Phase Cooling products for power electronics applications. “Pumped Two Phase Cooling is a growing technology area for ACT,” said … [Read more...]
Heat Exchangers Cool Electrical Enclosures, Keep Dust Out
Industrial air conditioner units are typically the solution for cooling sealed enclosures. What designers sometimes fail to consider, however, is that a cooler ambient environment could be used to help cool warmer electrical enclosure, particularly when there is a temperature difference between the internal target temperature and the surrounding temperature of ∆T≥10°C. … [Read more...]
You’re Sending That Heat “Away” to Where, Exactly?
Engineers are generally hard-nosed realists and don’t rely on the mythical kingdoms of fairy tales where only good things can happen and all problems disappear. Still, there is one magical place which is often called out when dealing with the thermal aspects of design, and it has the simple name of “away.” How so? Cooling devices and techniques – including heat sinks, heat … [Read more...]
