Liquid cooling technology is a cooling technology that uses liquid as the heat transfer medium, and the heating device exchanges heat with the liquid through direct or indirect contact. In common understanding, liquid cooling is the process of replacing air with liquid to remove the heat generated by IT heating devices such as CPUs and memory, similar to cooling a server locally or even soaking it all. At present, liquid cooling technology can be described as a hundred flowers blooming, with common ones being cold plate liquid cooling, immersion liquid cooling, and spray liquid cooling. Among them, immersion liquid cooling has the highest heat transfer efficiency and can avoid local hot spots, making it the most likely technical means to solve various problems faced by heat dissipation systems in high-performance computing environments
The most common way to dissipate heat in liquid cooled data centers on the market is to use coolant, and fluorocarbon coolant is the most commonly used coolant on the market. Why can fluorocarbon coolant break through the tight encirclement and gain the favor of entrepreneurs in a fiercely competitive environment?
1. Anti freezing and anti icing: When the water temperature is 0 ° C, it can have a certain anti freezing effect and prevent equipment or pipelines from freezing at low temperatures.
2. Scale removal and anti-corrosion: It has strong oxidizing properties and can remove water rust, iron rust, and other dirt within the system. In addition, it also has a anti-corrosion effect, mainly referring to the corrosion of equipment.
3. Reduce metal corrosion rate and improve metal corrosion resistance: reduce equipment maintenance frequency.
4. Prevent the formation and deposition of scale: Avoid blocking the heat exchanger due to scale and affecting the heat transfer effect.
5. Improving water quality: Increasing the content of dissolved oxygen in water is beneficial for the reproduction and growth of microorganisms, and inhibits the formation of calcium carbonate precipitation.
Specifically, fluorocarbon coolant is a colorless and transparent perfluorocarbon liquid chemical with ideal chemical inertness, excellent thermal conductivity, excellent electrical insulation performance, extremely low surface tension, and good system compatibility. It can be widely used in various temperature controlled heat dissipation systems.
