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...]
The Impact of Hybrid Cooling on the Power and Computational Efficiency of Cloud Computing Racks
A noteworthy trend in data centers is to reduce the power consumption of cooling facilities by increasing the supplied temperature to IT services, thereby requiring less work within the cooling facility to provide the targeted temperature. This will result in lower overall power consumption and higher computational effectiveness. However, higher inlet water temperature to the … [Read more...]
