Microsoft’s Surface Book 2 is long overdue for an upgrade and
it appears that Microsoft will push the limits even further
with the next version. The long-awaited Surface Book 3 could
come sport an entirely new thermal management system that would
keep it cool under different processing conditions.
According to a patent filing uncovered by
us, Microsoft’s Surface Book 3 may come with adaptive airflow
guides. Based on the description of the patent, the mysterious
device appears to be part of the Surface line, but the
technology can be implemented in gaming consoles as well.
In the filing, Microsoft says airflow guides may provide
optimal thermal management for laptops and minimize acoustics
(mechanical waves) in the device for a plurality of rotational
The company also suggested that its new optimal thermal
management may deliver improved performance and increase in
Surface Book’s life expectancy.
The thermal management includes a fan and the fan has been
designed to move air through an open outlet of the fan. The
system also uses one airflow guide, which is positioned
adjacent to the outlet opening.
The airflow guide’s role is to direct the movement of the air
from the outlet and reduce heat within the flagship device.
Multiple airflow guides are used and one is configured to pivot
about an axis to move between a first position to a second
position based on a change in rotational speed of the fan.
The function of adaptive airflow guides is apparently based on
the temperature detected by the thermal sensors. Based on
the data, fan speed may be set and one or more airflow guides
will be adjusted to adapt to the airflow configuration for the
specific fan speed.
In an effort to efficiently cool the computing device, the fan
speed may be adjusted (e.g., increased) to meet the new
demanded cooling capability,” the company noted.
In simple words, Microsoft is claiming that the features of the
new thermal system may provide better heat management in
laptops and 2-in-1s.
