In today's episode of Tech Diaries, let's dive into one of the coolest (literally!) innovations in flagship smartphones: liquid cooling.

If you've ever wondered how your high-performance device stays cool during intense gaming sessions or multitasking marathons, this thread will give you all the details!


What is Liquid Cooling?

Liquid cooling is a heat dissipation technology used to prevent smartphones from overheating by efficiently transferring excess heat away from the device's components.

Flagship smartphones with powerful processors, high refresh rate displays, and intense gaming capabilities generate a lot of heat during extended usage. Liquid cooling helps to maintain optimal performance by managing these temperature spikes.

How Does Liquid Cooling Work in Smartphones?

Liquid cooling in smartphones typically involves a closed-loop system with a liquid coolant, usually water or a special thermal fluid. Here's how the process works:

  1. Heat Generation:
  2. When you're using power-intensive apps (like gaming, video streaming, or multitasking), the processor (CPU) and graphics unit (GPU) generate a lot of heat.
  3. Heat Absorption:
  4. A thermal plate or heat pipe absorbs this heat. In advanced systems, a graphene sheet or copper heat sink may help increase the heat absorption efficiency.
  5. Liquid Circulation:
  6. The absorbed heat is transferred to a liquid coolant that circulates within a small cooling chamber. This liquid is designed to quickly absorb and move the heat to other parts of the phone.
  7. Heat Dissipation:
  8. The heated liquid is passed through a cooling mechanism, like a vapor chamber, which is often made of copper or a similar material. The heat dissipates into the environment, either through passive methods like convection or through an active heat sink.
  9. Cooling Effect:
  10. After the heat is dissipated, the liquid coolant cools down and is ready to circulate again. This cycle keeps the smartphone's internals at an ideal temperature.

Types of Liquid Cooling Used in Smartphones

  1. Vapor Chamber Cooling:
  2. Found in many flagship devices, it involves a sealed chamber with liquid inside. When the liquid evaporates, it carries heat away, and as it condenses, it returns to its original state. This is highly efficient and compact.
  3. Heat Pipes:
  4. These are tiny tubes filled with a special liquid that absorbs heat from the processor and releases it at another point in the phone. They are typically combined with graphene or copper plates to improve performance.
  5. Graphene-based Cooling:
  6. Some flagship smartphones use graphene layers as part of their cooling system. Graphene is a highly conductive material that spreads heat more effectively across the phone, preventing hot spots.


Why is Liquid Cooling Important?

  1. Maintains Performance:
  2. Excessive heat can throttle your device's performance. Liquid cooling helps keep temperatures low, ensuring your smartphone runs smoothly without performance dips during gaming or heavy multitasking.
  3. Improved Battery Life:
  4. When a phone is overheated, it can lead to battery degradation over time. By managing the temperature, liquid cooling can extend the overall lifespan of your device's battery.
  5. Better Gaming Experience:
  6. For gamers, this technology is a game-changer! Liquid cooling ensures your device doesn't overheat, giving you a consistent, lag-free experience during long gaming sessions.

Liquid Cooling in iQOO Smartphones


Flagship iQOO smartphones, such as the iQOO 12, integrate advanced cooling systems to ensure you get the best performance, even under the most intense usage scenarios. By combining liquid cooling with other technologies, iQOO devices keep the heat under control, so you can game and multitask for longer periods without worrying about performance throttling.
