New Breakthrough in Smartphone Cooling? Top 5 Flagship Phones to Feature Built-in Fans in the Second Half of the Year

IT Home, February 24 Digital blogger @DigitalChatStation revealed that a top 5 flagship smartphone slated for release in the second half of this year is currently evaluating a built-in fan cooling technology. While the blogger didn't disclose the manufacturer, the news has sparked widespread industry attention, suggesting a potential major revolution in smartphone cooling technology.

Currently, the mainstream smartphone cooling solution relies heavily on Vapor Chamber (VC) technology. VCs typically utilize copper or stainless steel and contain a micro-structured vacuum chamber. The cooling principle involves four steps: conduction, evaporation, convection, and condensation. It leverages the heat absorption during liquid evaporation and heat dissipation during condensation to circulate and dissipate heat within the phone, ultimately lowering the temperature of the hottest areas to match the ambient temperature. The ingenious design of the VC ensures efficient heat transfer, effectively reducing the temperature of core components.

However, even with significant advancements in VC technology, it struggles to completely solve smartphone overheating issues due to increasing performance demands. Three key factors contribute to this: firstly, continuously improving processor performance leads to increased power consumption and heat generation; secondly, the consumer preference for slim and lightweight phones restricts the size and space available for cooling components; and thirdly, the increasingly compact arrangement of internal components leaves less room for the cooling system, further intensifying the challenge.

To address the increasingly severe smartphone overheating problem, manufacturers have adopted various approaches, constantly exploring and improving cooling solutions. However, existing technologies still fall short. Some manufacturers enhance cooling efficiency by adding materials like graphene to their VCs, while others employ more complex designs, such as stacking multiple VCs.

It's worth noting that some manufacturers have previously experimented with built-in fans to improve cooling. The Red Magic 9S Pro+ utilizes a built-in fan combined with liquid cooling, achieving satisfactory results. Additionally, Transsion's Infinix introduced the CoolMax active fan cooling system, claiming a 10C temperature reduction on a phone with the Dimensity 9300 chipset. These examples demonstrate the potential of built-in fan technology.

However, built-in fan technology faces challenges. Firstly, fans increase phone thickness and weight, contradicting the desire for slim devices. Secondly, fan operation generates noise, impacting user experience. Finally, fan power consumption must be considered, as it could affect battery life. Balancing cooling performance, phone thickness, noise, and power consumption is crucial for successfully implementing built-in fan technology in high-end flagship phones.

@DigitalChatStation's mention of a "top 5 flagship phone" using built-in fan cooling is exciting news. If true, it suggests a significant breakthrough, allowing for effective cooling in high-end phones while maintaining a slim profile. This would be a major milestone in smartphone cooling and could signify a shift in the technology's future direction. We eagerly await the release of this flagship phone and whether built-in fan technology can truly solve high-end smartphone overheating. If successful in delivering significant cooling improvements without excessively impacting thickness, weight, battery life, or noise, it will undoubtedly become a major trend in the smartphone industry, boosting performance and user experience. However, time and continued technological advancements will be necessary to validate its effectiveness.
