Microsoft patents active cooling solution for Surface tablet

Microsoft has filed a new accessory patent for its Surface tablet, which will allow both parties to dissipate heat while docking for higher performance. The so-called Thermal Dock will include active heat dissipation through a combination of Peltier heat sinks and fans, and will be equipped with a spring-loaded heat sink that is connected to the tablet via magnets to ensure good thermal contact.

In addition, the dock and tablet will communicate in a way that increases processing power when the tablet is in the dock, and reduces processing power when disconnected, making the Surface tablet an alternative to desktops, while not affecting battery life when disconnected, making the device thinner, less fanless when used on the move, but still actively dissipating on the desktop.

Microsoft said in its patent that a thermal management system includes a thermal base, which includes computing devices that can be used to operate to cool physical contact with the thermal base. The thermal base comprises a housing, a first thermal management device supported by a housing, and a second thermal management device physically connected to the first thermal management device. The first thermal management device and the second thermal management device are different types of thermal management device.

The patent was filed on July 17, 2019 and announced on May 12, 2020, and Microsoft may use it in products that will be released in the near future.
