Many biological creatures are enabled with the ability to “see” the heat – reptiles, for example, effectively use this ability to detect the size of the heat-emitting object and its range. Other biological entities, including mammals, are enabled with the ability to perceive heat by a process known as Thermoception or Thermoreception. As humans, we are capable of sensing … [Read more...]
Computational Modeling of a Novel End-of-Aisle Close-Coupled Cooling Solution
Data centers are mostly managed by overly conservative thermal management approaches [1]. The typical thermal solution for data centers is perimeter computer room air handlers (CRAH). The traditional cooling method includes supplying air through raised floor plenum that is blown by the CRAH blowers, and the chassis fans, typically located at the rear end of the IT equipment, … [Read more...]
Laird Launches Active Transceiver Coolers for Optical Communications Market
Optimized thermoelectric-based Active Transceiver Coolers remove heat in remote radio units to enable higher data transmission speeds and lower latency in next generation communication networks… May 17, 2017 – Global technology leader Laird (LRD: London) has developed a new platform of customizable thermoelectric assemblies (TEAs) specifically designed for thermal … [Read more...]
The Problem with Effective Thermal Conductivity
Simply stated, the problem with the use of volume weighted, effective thermal conductivity, kvw, in the thermal modeling of a printed circuit board (PCB), is inaccuracy. In this paper, we show how using kvw can lead to serious errors in the prediction of PCB temperatures. We recommend two, related, alternative procedures that provide greater … [Read more...]
