Mobile technology: why we need liquid cooling in our smartphones

By Zia Askari

We all want our smartphones to do more for us, especially when we’re playing games or engaged in video calls for long durations. However, their small form factor coupled with heavy use of CPU/GPU intensive applications causes smartphones to overheat.

Once the phone gets hot enough and reaches a certain temperature, the operating system (OS) slows down the performance of the phone by 10-20%. This leads to lag in device performance and hampered user experience. Liquid cooling is the answer to this problem.

Liquid cooling in a smartphone works on the basic principle of heat dissipation. Smartphones with this technology come with a pre-installed heat pipe that contains a coolant. Whenever there is a need, this pipe absorbs the excessive heat generated by the processor and turns the liquid present in the pipe into vapor. This results in a considerable drop in the temperature of the device. This also helps to increase the lifespan of the SoC in the device.

As for the latest devices that have incorporated this liquid cooling technology feature, Samsung’s latest flagship device, the Samsung Galaxy S22 Ultra, is specially designed to help the device stay cool during sustained heavy usage like playing games or watching UHD videos. The Galaxy S22 Ultra deploys a new heat transfer technology called Gel-TIM. This is designed to help dissipate heat in a more efficient manner than ever before and as a result, better sustained performance results. Samsung’s Gel-TIM is a thermal paste used for the CPU. According to the company, this allows it to transfer heat 3.5 times more efficiently than last year’s device.

Likewise, the iQOO Neo 6 series is equipped with the latest cascade cooling system. With uneven thickness of graphite structure, the 5-layer 3D graphite cooling plates of the waterfall cooling system make better use of the phone’s internal space, fit the heat source tightly, and further accelerate the heat transfer, creating a “cascading” effect. According to the company, this technology has achieved a large cooling area of ​​up to 36,907 mm and promises a good gaming experience anytime, anywhere.

Among other things, the OnePlus 10 Pro is equipped with a 3D passive cooling system that helps disperse heat efficiently and guarantees both casual and experienced users optimal performance for a long time. The device’s 5-layer 3D passive cooling system, for example, provides a cooling area of ​​over 34,119.052 mm and features a large custom vapor chamber, copper foil, a new Graphene cooling film and copper carbon on both sides of the motherboard.

In short, our smartphones also need to stay calm and cool.
