Abstract: TSMC is the world's largest semiconductor wafer foundry, the annual power consumption is amazing, and the electricity bill is also a huge cost. According to Taiwan media reports, TSMC has adjusted the backup power supply system architecture of its high-performance computing computer room and changed it to a lithium iron phosphate battery DC power supply system to improve power efficiency, and at the same time, heat dissipation has also been upgraded to immersive liquid cooling, and it is expected to save 400 million kWh per year from 2030.
TSMC is the world's largest semiconductor wafer foundry, which consumes amazing electricity every year, and the electricity bill is also a huge cost. According to Taiwan media reports, TSMC has adjusted the backup power supply system architecture of its high-performance computing computer room and changed it to a lithium iron phosphate battery DC power supply system to improve power efficiency, and at the same time, heat dissipation has also been upgraded to immersive liquid cooling, and it is expected to save 400 million kWh per year from 2030.
According to the report, TSMC recently announced the upgrade of the power supply system of the computer room, and the lead-acid battery and UPS uninterruptible power supply system used before will be eliminated and upgraded to a lithium iron phosphate DC power supply system, with higher power supply efficiency.
In addition to improving the power supply system, another major power consumer is the computer room cooling system, TSMC will cooperate with Delta, GIGABYTE, Zhibang, 3M and other companies to develop immersive cooling technology, which is expected to reduce the energy consumption of the server by 15% to 30%.
This immersive liquid-cooled cooling system can soak the server in a sealing tank, and the temperature of the system and chip does not exceed 50 degrees, which not only has a better heat dissipation effect, but also improves the operating performance by 10%.
TSMC's immersive cooling system was piloted at the 12B fab in Q4 last year, and will be introduced into the 18A fab in Q1 this year, and it is expected to save 400 million kWh of electricity per year from 2030.
