What Are the Differences Between Vacuum Brazing and CAB for Liquid Cold Plates?
Quick Answer Vacuum brazing and CAB (Controlled Atmosphere Brazing) are two thermal joining methods for aluminum liquid cold plates. Vacuum brazing uses a high-vacuum furnace with no flux, producing cleaner, higher-strength, leak-tight joints ideal for high-reliability applications. CAB uses nitrogen atmosphere with flux, offering lower cost and faster cycle times for standard, less demanding cold […]
How to Prevent Galvanic Corrosion in Dual-Metal Liquid Cooling Loops
Quick Answer Galvanic corrosion in dual-metal liquid cooling loops is prevented by electrically isolating dissimilar metals, selecting metals close together on the galvanic series, using corrosion-inhibited coolant, and controlling coolant conductivity. Common prevention methods include dielectric fittings, sacrificial anodes, protective coatings, and proper coolant chemistry management to stop electrochemical reactions between copper, aluminum, and other […]
Liquid Cooling Cold Plate Leaks: Causes, Testing & Prevention
Liquid cooling cold plates and liquid-cooled assemblies are increasingly used in high-density electronics, data center infrastructure, electric vehicle battery systems, industrial power modules, and other applications where conventional air cooling cannot provide sufficient heat removal. By circulating coolant through internal channels located close to heat-generating components, a cold plate can move large amounts of thermal […]
How Does Computational Fluid Dynamics (CFD) Optimize Heatsink Design?
Computational Fluid Dynamics (CFD) improves heatsink design by enabling data-driven decisions before physical prototypes are built. It allows engineers to optimize fin geometry, airflow paths, and hotspot control early—especially for AI processors, GPUs, and high-power electronics—resulting in faster validation and more reliable cooling performance. What Is Computational Fluid Dynamics (CFD)? CFD is a simulation method […]
Why Do Some Areas of a Liquid Cold Plate Run Hotter Than Others?
Liquid cold plates are widely used to cool high-power electronics that generate more heat than conventional air-cooled systems can manage effectively. Common applications include AI servers, GPU clusters, electric vehicle batteries, industrial inverters, semiconductor equipment, power electronics, and high-performance computing systems. Although liquid cooling can remove a substantial amount of heat from a compact area, […]
How to Prevent Condensation in Liquid-Cooled Electronics
Liquid cooling can remove high heat loads more efficiently than many traditional air-cooling systems. However, lowering component temperatures introduces an important reliability concern: condensation. When a cold plate, coolant tube, fitting, manifold, or nearby metal component becomes colder than the surrounding air’s dew point, moisture can collect on the exposed surface. Even a small amount […]
How Custom Cold Plate Design Improves Thermal Performance
In the high-stakes world of power electronics and hyperscale computing, “good enough” cooling is no longer an option. As chips push the boundaries of heat flux, standard cooling components often become the bottleneck that limits performance. This is where custom cold plate design transforms a system from a thermal liability into a high-performance asset. How […]
What Is Cold Plate Cooling and How Does It Work?
As electronic components shrink in size while growing exponentially in power density, traditional air-cooling methods are reaching their physical limits. For high-stakes applications like electric vehicle (EV) batteries, artificial intelligence (AI) server clusters, and high-power industrial inverters, the solution is increasingly shifting toward liquid cooling. At the heart of this shift is the cold plate. […]
