Apple's AR devices, likeThis time, two new patents illustrate this dedication, one of which involves sweat and heat dissipation.
Apple said in its patent:
The second patent released today focuses on keeping the wearer cool. In the patent, apple states that in known systems, such as wearable head displays, display panels are usually supported by carriers, frames, or other such structures, which are usually made of lightweight materials (such as plastic) to reduce the overall weight of the system. However, these structures have little benefit in terms of thermal regulation, and without proper cooling and heat dissipation, they often lead to irreparable damage or system failure.
apple points out that existing systems usually add additional components, such as heat sink, to achieve heat dissipation, but these components also bring wearer comfort issues and increase the overall weight of the system. apple's solution is to reduce the working temperature and extend the service life of the system by providing a display system that integrates thermal solutions into structural components, not only reducing the overall number, complexity and weight of the display system, but also increasing thermal conductivity and improving thermal management.
That's not to say that Apple has any particularly new ways to cool or reduce heat, and the company aims to take advantage of hardware that already has to exist. The hardware includes the display panel plus the carrier supporting the first side of the display panel. The carrier, or frame, is a thermal solution to facilitate the transfer of heat from the display panel. A further step is to include a heat sink that works but does not adversely affect the wearer. There are also solutions that mean that the components move in order to generate airflow for heat dissipation.
