Important Innovative Technology

BiFrost composite cooling management system

The cooler and quieter BiFrost composite cooling management system is designed for desktop computers where special dual fan configuration allows most of the air to be exhausted and only part of the hot air remains inside. Coupled with the Vapor Chamber design, it can effectively reduce the internal temperature of the computer through its extremely high temperature uniformity and conductivity. Compared with the dual-axial fan design, the intake air temperature of the graphics card can be reduced by up to 7 degrees.

This design is combined with the 5^th generation Acer AeroBlade 3D metal fan that was only available in Acer notebooks which is 87.5% thinner than normal generic plastic fans and can increase the airflow during rotation, and with axial FrostBlade™ 2.0 technology to keep the system cool and ventilated at any time; it utilizes a static pressure design to optimize airflow while reducing vibration and noise and speeding up the cooling via a new arc-shaped design along the ends of the fins. This design is applied to the Predator BiFrost Intel^® Arc™ A770 OC graphics card launched by Acer and Intel in 2022.

Efficient anti-vibration speaker and module design

In recent years, working from home, remote meetings, and remote teaching have become the new normal due to the impact of the Covid-19 pandemic. The use of video conferencing has played a crucial role in mobile devices and notebook computers. During video conferences, users commonly use headphones (wired or wireless) and the speaker system of notebook computers as output devices.

Given the frequent and probabilistic long-term use of headphones during remote work and distance learning at home, it is crucial for us to consider how to reduce or avoid hearing damage to users in our product development and design. Mobile devices, primarily notebook computers, are key to remote work and distance learning at home. Therefore, the performance of the notebook computer speaker system is of utmost importance. However, the trend of lightweight and slim notebook computer designs significantly affects the quality and volume of the speaker system, resulting in an inability to provide good audio performance (high loudness, low distortion, faithful sound reproduction, etc.) during video calls or leisure activities, such as listening to music or playing video games. The maximum audio performance of almost all notebook computer audio characteristics will be compromised in order to address issues of resonance noise and audio distortion. 

By incorporating high-efficiency anti-vibration speakers and their modules into notebook computers, vibrations of speaker modules can be prevented from being transmitted to other components, thereby avoiding resonance noise and optimizing audio performance. This design has already been adopted in two models of gaming notebook computers in 2022 and 2023, and we plan to adopt it in two additional models in 2024.

AI Smart Charging according to user behavior

For users maintaining a regular habit of using computers for daily life and work, there will also be a certain behavioral pattern. For instance, a fixed behavioral pattern may involve shutting down and charging the computer at 11 PM,and then turning it on for use at 7 AM in the morning. Acer's battery management system will optimize the charging algorithm for different user behavior patterns, thereby delaying battery aging and increasing battery life.

The AI Smart Charging feature can be enabled on Acer notebook computers using the built-in program, Acer Sense. By learning the user's behavior through AI, different charging strategies are applied to optimize the battery life for each user. The system aims to delay the battery from reaching full charge when the power supply is available, keeping it in a low voltage storage state to slow down the aging process. The entire charging process is completed before disconnecting the power supply, ensuring that each user has access to the full 100% battery capacity. Both the learning and charging processes are fully automated and tailored to each user.

Based on the results of testing in our internal laboratory environment, enabling the AI Smart Charging setting improves battery health by over 25% after 500 charge-discharge cycles. Additionally, it reduces the battery's prolonged exposure to high charge levels within the same charging time, thereby extending the battery's lifespan.

With regard to this solution, we successfully completed the development and verification of the functional prototype in 2022. In 2023, we implemented five representative models for production evaluation confirmation. Furthermore,in the first half of 2024, we will include two additional models for quality evaluation confirmation. We anticipated to further expand the implementation to include more models in the second half of 2024.
