UL Solutions Launches Certification for Direct-to-Chip Liquid Cooling Equipment Used in AI Data Centers

NORTHBROOK, Ill.--(BUSINESS WIRE)--Sep 29, 2026--

UL Solutions Inc. (NYSE: ULS), a global leader in applied safety science, today launched a certification program for liquid cooling subassemblies that target powerful chips directly, providing more effective cooling in AI data centers and other high-density computing systems.

AI computers use chips that produce a large amount of heat. If that heat is not removed, equipment may slow down, shut off or become damaged, but traditional air cooling, such as fans or chilled air, may not be enough for today’s most powerful computing systems. With direct-to-chip liquid cooling, coolant flows through a cold plate that is attached to the chip. The coolant absorbs heat from the chip and carries it away, much like water flowing through a radiator.

“As AI data centers handle more powerful computing, they depend on even more advanced cooling systems to operate safely and reliably,” said Jennifer Scanlon, president and CEO of UL Solutions. “Our certification helps IT equipment manufacturers demonstrate product performance and safety while giving data center operators greater confidence during integration.”

AI and other high-performance computing systems are increasing energy use and heat in data centers. Global data center electricity use is expected to more than double between 2024 and 2030. Cooling can account for up to 40% of a data center’s energy use. Liquid cooling can improve heat control, but it also brings risks. Leaks, corrosion, contamination or parts that do not work well together can affect system safety, performance and reliability.

Connecting parts from different suppliers can also be a challenge. Parts may fit together but require different coolants, pressure levels or operating conditions. Industry observers have identified integration problems and limited standards as barriers to wider use of liquid cooling.

The UL Solutions certification program covers eligible liquid-filled parts and subassemblies that move coolant through information and communication technology equipment. These may include:

UL Solutions uses UL 4501, the Outline of Investigation for Safety, Performance and Interoperability of Liquid-Filled Components and Assemblies Used in Liquid Cooling Systems, to evaluate eligible liquid cooling subassemblies. The evaluation covers coolant compatibility, pressure and leak integrity, durability, liquid flow, interoperability, production controls and installation requirements.

Evaluating these parts before adding them to a complete cooling system can help identify problems earlier and reduce the need for repeated testing. Independent certification demonstrates that an eligible product meets applicable requirements. This helps manufacturers support their product claims and helps data center customers make informed buying and integration decisions.

“AI infrastructure must scale without sacrificing safety or reliability,” said Milan Dotlich, vice president and general manager of Data Center Solutions at UL Solutions. “Independent evaluation of liquid cooling components can help organizations deploy advanced computing systems with greater confidence.”

UL Solutions can also evaluate other data center cooling equipment under applicable UL Standards. This equipment includes coolant distribution units, self-contained liquid-filled systems, liquid-cooled busways, cables, connectors, power whips, gaskets, O-rings and hoses. Requirements depend on each product’s design, function and intended use.

A former Ohio music pastor who once appeared on “American Idol” was convicted of murder Tuesday in the killing of his wife while he was having an affair.

Prosecutors said Caleb Flynn, 40, staged a home invasion in February after shooting his wife, Ashley Flynn, a 37-year-old schoolteacher and volleyball coach.

Flynn, who claimed his wife was killed by a burglar, could now be sentenced to life in prison without the chance of parole. He closed his eyes, shook his head to the side and fought to maintain his composure as the judge read the guilty verdicts to murder, felonious assault and tampering with evidence.

Flynn appeared on “American Idol” in 2013, telling TV viewers about how his wife had encouraged him to chase his dreams on the singing competition. He sang before judges Mariah Carey, Randy Jackson and Nicki Minaj but did not advance to the main competition in Hollywood.

Prosecutors told jurors during closing arguments Tuesday that Flynn wanted out of his marriage when he shot his wife at their home in Tipp City, a suburb north of Dayton. Flynn and the couple’s two daughters were home when police arrived.

Flynn also didn’t want to lose his daughters, his high-paying job at his wife’s family business or his position in the church, prosecutors said.

“He wanted to keep his mistress and have his daughters all to himself,” said Matthew Joseph, an assistant Miami County prosecutor.

During the trial, a woman who said she was having an affair with Flynn testified that he said he hated his wife and had thoughts of killing her.

Flynn’s attorney told the jury Tuesday that investigators never found a gun or evidence that Flynn fired a gun that day.

“His being unfaithful doesn’t equal murder,” said defense attorney Patrick Mulligan. “The issue here isn’t, ‘Was he a good husband?’”

Text messages Flynn sent to his lover complaining about his wife were meant to make her feel good, Mulligan said.

Alleigha Botner testified she met Flynn in 2022 while she was a 20-year-old intern at his church and had an affair with him for more than a year. Botner read some of her text messages with Flynn.

About six months before the killing, Flynn wrote: “I was up until 4 a.m. last night crying, literally trying to think of ways to kill her and not go to jail.”
