Patent attributes
A head-mounted display (HMD) device includes a printed circuit board having one or more processors. A heat transfer plate having a heat-generating component facing surface is thermally coupled to the printed circuit board. The HMD exterior-facing surface of the heat transfer plate opposite from the heat-generating component facing surface is thermally coupled to a heat pipe. The heat pipe is thermally coupled to a heat transfer shell, which is configured as a heat sink to receive heat from the heat pipe. In operation, heat flows from the heat-generating components of the HMD (e.g., the HMD's processor and other electronic components) to the heat transfer plate. Thermal energy removed from the heat-generating components is transferred to the heat transfer shell via the heat pipe, which in turn transfers the heat to the external surface of the HMD to be dissipated into ambient room temperature of the surrounding environment.
