These are the show’s leading actors. But just like every pop artist has a team supporting them, the OPPO Find X5 Pro has something equally significant. This is the cooling system for the OPPO Find X5 Pro. It is what enables the OPPO Find X5 Pro to remain composed under pressure. When playing a detailed 3D game, you won’t feel its back becoming uncomfortablely warm. The phone won’t overheat to the point where you have to stop recording 4K video. A powerful phone’s full potential can be realised with a great cooling system.
The OPPO Find X5 Pro is a smartphone with a number of standout features that vie for attention. It has the most cutting-edge camera system, two superb Sony IMX766 flagship sensors, and MariSilicon X. Whether you utilise a cable or wireless pad, the super-charged SUPERVOOC technology quickly recharges its battery.
The phone’s cooling system’s ultimate goal is to go unnoticed and uncredited but perhaps it is time to give the OPPO Find X5 Pro’s cooling some credit and figure out how this unlikely goal was achieved. A vapor chamber is the heart of the phone’s cooling system. It is an ultra-thin copper cave injected with a very small amount of liquid. As heat from the components underneath conducts through the chamber’s bottom, this liquid evaporates and spreads throughout the chamber. It condenses on the outer walls, spreading the heat it held over a much larger surface area, dissipating the heat in the process.
Perfecting cooling system in a phone is not a simple process. The OPPO Find X5 Pro uses a full passive cooling solution, generating zero noise and all its pieces have to slot in around the core components in a precision-crafted case less than 9mm thick. Each step of the process is guided by the human body’s perception of temperature. There can be no hot spot on the phone’s back that your fingers will notice, no heat build-up to distract from whatever you choose to do with your OPPO Find X5 Pro.
It almost completely covers the battery and SoC, the main processor, which is exactly where you want such a chamber to sit. When fast-charging or playing a console-grade game, any heat generated is quickly spread across a huge area so it can dissipate almost unnoticed, out through the phone’s back. But the vapor chamber is only a single part of a whole one-way circulatory system that runs through the phone. Advanced materials engineering is used to pull warmth away from all the key components.
The larger a vapor chamber is, the wider and more effectively it can move heat away from the components that generate it, like the primary processor. OPPO has managed to increase its size by 75% over the previous generation.
Copper is the traditional material for cooling components. However, when devising heat management for the display, OPPO’s R&D team found they could improve both heat dispersal and the resilience of the screen by using a copper sheet sandwiched with an ultra-thin layer of graphite. This material helps keep the display cool while delivering searing brightness at 120Hz, while also dramatically improving the drop resilience of the OPPO Find X5 Pro by increasing structural integrity.
The other hot zones in a phone, like the motherboard and battery coil, did not need the same level of structural support, letting OPPO R&D dig even further into possible solutions. They landed on a graphene film which dramatically improves strength and conductivity.
Following years of experimentation and fine-tuning, OPPO has achieved a 50% improvement in thermal conductivity of the graphene film compared to its first-generation process, for industry-leading performance. The compromise-free cooling system lowers the OPPO Find X5 Pro heat to a comfortable range even when running a 90/120 Hz high refresh game and keeps the phone cool while charging.
