Technical Cleanliness

Global Liquid Cooling Industry Booms: Component Cleanliness Becomes Core International Supply Chain Threshold   Driven by the rapid expansion of high-density AI computing clusters and global data center energy efficiency upgrades, liquid cooling has fully replaced traditional air cooling as the standard heat dissipation solution for high-power servers worldwide. The global liquid cooling market is undergoing explosive growth in 2026, with hyperscale cloud infrastructure, new energy storage, and electric vehicle systems serving as the primary global demand drivers. Most importantly, technical cleanliness of thermal fluid components has transitioned from an optional quality check to a mandatory supply chain qualification standard, with VDA19.1 and ISO16232 now widely specified by intern...

What Types of Contaminants Does Technical Cleanliness Primarily Control?   Content Summary Technical Cleanliness, typically evaluated in accordance with standards such as ISO 16232 and VDA 19.1, is designed to quantify and control microscopic foreign matter that can affect the performance, reliability, and service life of precision components. In practical cleanliness testing, contaminants can generally be categorized according to their physical form and material properties, including metallic hard particles, non-metallic hard particles, non-metallic soft particles, fibers, and liquid or film-like residues. These contaminants can originate from machining and manufacturing processes, production environments, handling and packaging, as well as component assembly and early-stage operatio...
