Previous articles in this series described how thermocouple wire size [1] and thermocouple attachment method [2] can affect steady state temperature measurements. This article briefly discusses how these factors can affect the transient response of thermocouples when used to monitor temperatures that change value over time. Bare Thermocouple Junction Before addressing … [Read more...]
Tech Brief: Thermocouple Attachment
The previous article in this series on thermocouples described how the size of the thermocouple wire could affect its accuracy [1]. This is particularly true if the wire is exposed to high convection coefficients. This article addresses a separate issue, namely the degree to which the attachment method impacts thermocouple readings. As it turns out, once again the … [Read more...]
Summary of the IEEE ITherm 2023 Conference
The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the JW Marriott Grande Lakes, Orlando, FL, May 30 – June 2, 2023. This was the 22nd ITherm, which was first held in 1988. The conference was historically held every other year until 2016 when it switched to an annual schedule. ITherm 2023 was sponsored by the … [Read more...]
Statistics Corner: Weibull Distribution
A little over a pandemic ago, the first article in this series on statistical analysis mentioned that a fundamental aspect of statistics is that one assumes a mathematical model that describes the distribution of a data set and then uses that model to estimate the probability that a given value or set of values will occur [1]. This allows us, for example, to estimate whether … [Read more...]
Heat Transfer and Pressure Drop Correlations for Manifold Microchannel Heatsinks
Written by: Sevket U. Yuruker, Raphael K. Mandel, Amir Shooshtari and Michael M. Ohadi - Department of Mechanical Engineering, University of Maryland Conventional microchannel cooling has been proven capable of removing high heat fluxes, but usually at significant pressure drops. On the other hand, manifold microchannel systems offer high heat transfer coefficients/heat … [Read more...]
