This article describes a semi-empirical equation that can be used to assess radiation heat transfer in terms of an effective convection coefficient. The effective convection coefficient due to radiation is shown to be: Where temperatures are in °C and ε is the emissivity of the radiating surface. This equation is accurate to within ~10% over a temperature range of 0 - … [Read more...]
Utilizing Boyd Coolant Distribution Units (CDUs)
Introduction Let's begin with two images that may be familiar, but will provide a very good illustration to help us frame the current market trend and why liquid cooling is on the rise. The two charts in Figure 1 show actual CPU and GPU power consumption over the years, and Figure 2 shows an overall trend in chip power. As we can see here at this point, in 2023 at 700 … [Read more...]
Revolutionizing Data Center Sustainability with Intelligent, Purpose-Built Solutions
Introduction By pairing an air-cooled, magnetic bearing chiller and mission-critical air handling units with the sophisticated AI capabilities of open-source digital platforms, data centers can reduce energy use by allowing for a dynamic — rather than static — chilled water setpoint. The primary objective for any data center is flawless data processing; critical to … [Read more...]
Cooling the Heat: A Journey Through Data Center Cooling Systems
Introduction Data centers play a vital role in the digital era by facilitating the storage, processing and distribution of vast amounts of information. As our world becomes more interconnected the demand for data centers keeps rising, which calls for efficient and sustainable cooling methods. It has been noticed that 42% of a data centers energy consumption is devoted to … [Read more...]
Thermal Management and Safety Regulation of Smart Watches
ABSTRACT A smartwatch is one of the most popular wearable devices now. Along with battery life and security, thermal safety is the most common concern. We show how to meet ergonomic standards for users and predict thermal performance in typical scenarios. Thermal simulation software applied at the design stage can provide guidance on the use of heat-spreading materials and … [Read more...]
