SMC switched to using lithium iron phosphate battery DC power supply system to power the computer room

Chip Research Institute reported on January 19 that TSMC is the world's largest semiconductor wafer foundry, and the annual power consumption is staggering, and the electricity bill is a huge cost. The company's computer room will be powered by lithium iron phosphate, and the heat dissipation will be upgraded with immersive liquid cooling. It is expected to save 400 million kWh of electricity every year from 2030.

According to reports, TSMC recently announced to upgrade the power supply system of the computer room. The lead-acid battery and UPS uninterruptible power supply system previously used 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 cooling system in the computer room. TSMC will cooperate with Delta, Gigabyte, Accton, 3M and other companies to develop immersive cooling technology, which is expected to reduce server energy consumption by 15% to 30%. . This immersive liquid cooling system can immerse the server in a sealed tank, and the temperature of the system and chip does not exceed 50℃, which not only has better heat dissipation effect, but also improves the operating performance by 10%.

TSMC's immersive cooling system has been piloted in the 12B fab in the fourth quarter of last year, and will be introduced into the 18A fab in the first quarter of this year. It is expected to save 400 million kWh of electricity every year from 2030.
