Abstract: A head mounted display device may include a housing, including a user-facing cavity and an electronics compartment. At least one fan may be installed in the electronics compartment. A plurality of intake ports may be defined in a peripheral wall portion of the user-facing cavity, and at least one air discharge port may be defined in a wall portion of the electronics compartment. A plurality of air channels may extend between the user-facing cavity and the electronics compartment. Operation of the at least one fan may draw external air into the housing through the plurality of air intake ports into the user—facing cavity, and into the electronics compartment through the plurality of air channels, for discharge from the housing through the at least one discharge port, to provide cooling of the user-facing cavity and the electronics compartment.
