As most readers are aware, the data center industry has put an increased focus on energy efficiency and environmental impact. Data centers in the United States are estimated to consume nearly 2% of the total electricity. The de facto metric used in the data center industry to evaluate energy efficiency has been the Power Usage Effectiveness (PUE), as defined by The Green Grid … [Read more...]
Thermocouples Basics Part 2: How They Are Made and Its Measurement System
Continuing from part 1, and the advantages of thermocouples, we will now visit the process to make a thermocouple and its measurement system. The way thermocouples are made is very simple. We have a thermocouple welder, shown in Figure 1, as a small machine. The ends of the two wires are twisted to digital wires together, and then each set of wires touches to the point where … [Read more...]
Thermocouple Basics Part 1: Advantages to Multi-Channel Isolated Thermocouples
Multichannel isolated thermocouples is a system that RECOM developed for use in a test lab. We will discuss how this will be useful for others to know the advantages and disadvantages of such a system. What is a thermocouple? It is two different types of metals that are joined together. In figure 1, we have a metal that's called chromel, and another one called alumel. When … [Read more...]
Guide to Simulation of Vapor Chambers as Anisotropic Conduction Heat Spreaders
Introduction Vapor chambers are passive two-phase devices used to spread heat from localized hotspots to larger surface areas. The device utilizes the latent heat of evaporation of an internal fluid to passively transport heat from the evaporator (heat source) to the condenser (heat sink) across very low-temperature drops. Condensed liquid returns to the evaporator from the … [Read more...]
Generative Design and Advanced 3D Printing: A Copper CPU Cooler with 55% Lower Thermal Resistance
Introduction Effective cooling is essential for CPUs, as they generate significant heat during operation while being very temperature sensitive. Improved cooling allows for maintaining the functionality of high-performance computer hardware. In this article, we demonstrate a unique approach to improving the cooling of high-performance components by combining thermal and … [Read more...]
