Abstract
A heat management device able to be manufactured using 3-D printing and corresponding to a body of a head mounted display system having an outer wall that partially encloses a chamber. The outer wall of the heat management device comprises a plurality of channels that traverse a thickness of the outer wall, each channel shaped to allow air to flow between the interior and exterior of the chamber, while preventing light from outside the chamber from entering the chamber. In some embodiments, each channel may be shaped to comprise a first portion and a second portion connected at an acute angle, the connection between the first and second portions serving to block a direct path for light to traverse between the ends of the channel.
