Abstract Data centers face challenges in balancing space and power, with studies showing that when power density exceeds 7kW per rack, IT equipment space utilization drops to 50%. Traditional cooling methods are reaching limits due to increasing demands from deep learning and AI, necessitating more space. Two-phase immersion cooling offers simplicity and cost savings … [Read more...]
Thermocouple Transient Behavior
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...]
Tech Brief: Effect of Thermocouple Size
Thermocouples are widely used for temperature measurements. They are particularly useful in lab testing, due to their relatively low cost and the ability to easily fabricate thermocouples of specific lengths for a given test. This Tech Brief discusses issues related to the size of a thermocouple that may be considered when using them. A thermocouple consists of two wires made … [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...]
