Brief Introduction of 1. PTFE Liquid Cooling Pipe
PTFE (polytetrafluoroethylene) liquid cooling pipe is a kind of high-grade plastic pipe specially designed for liquid cooling system. Liquid cooling systems are used in many applications, especially in high-performance computing, electronic equipment (such as the cooling of computer CPUs, GPUs, and other heat-generating components), and industrial cooling processes to efficiently conduct and dissipate large amounts of heat.
2. PTFE liquid cooling tube function
Heat transfer medium channel: As one of the core components in the liquid cooling system, the PTFE liquid cooling tube plays the role of transmitting the coolant, and the heat generated from the heat source (such as computer CPU, GPU or other industrial equipment) is transported through the coolant To the heat dissipation device (such as heat exchanger or heat dissipation row) for heat dissipation.
Heat and cold resistance: PTFE material has excellent heat resistance and low temperature toughness, and can maintain stable performance in a wide temperature range of -80 ℃ to 260 ℃, ensuring the normal operation of the liquid cooling system at extreme temperatures.
Low friction resistance: The inner wall of the PTFE liquid cooling tube is extremely smooth, which reduces the resistance of the coolant during the flow process, which is beneficial to improve the flow efficiency and overall heat dissipation effect of the coolant.
Chemical stability: PTFE has strong resistance to most chemical substances and will not be corroded by the components in the coolant, which ensures the stability of the coolant during the circulation process and prolongs the service life of the liquid cooling system.
Electrical insulation: In applications involving the cooling of electronic equipment, PTFE's good electrical insulation properties can prevent accidental short circuits between the cooling system and electrical components.
Reasons for choosing PTFE hose in 3. corrosion-resistant high-strength liquid-cooled pipeline components
The selection of hoses for liquid-cooled pipelines should take into account factors such as environmental adaptability, compressive strength, minimum bending radius, and reliability. At present, hoses supporting buckling assembly include rubber hose, nylon pipe and PTFE hose, but only PTFE hose can meet the working environment temperature and reliability requirements of avionics equipment of -55 ℃ ~ 70 ℃, and the compressive strength of PTFE hose with stainless steel braid layer can meet the design requirements, so PTFE hose with stainless steel braid layer is selected as the hose of liquid cooling pipeline assembly.
