US 10,379,583 B2 · System for discharging heat out of head-mounted display based on hybrid fan and heat pipe

Abstract

A head-mounted display (HMD) includes a hybrid fan, a printed circuit board (PCB) with one or more electronic components and a heat pipe to dissipate heat. The hybrid fan has a center axis extending from a rear side of the HMD to a front side of the HMD. The hybrid fan pulls air from a rear side of the HMD. The heat pipe has an end coupled to the PCB. The heat pipe partially surrounds a periphery of the hybrid fan and transfers heat away from at least the PCB. The HMD further includes a side cover and a front cover. The side cover encloses the hybrid fan, the PCB and the heat pipe. The front cover is attached to the side cover with a slit between an outer edge of the front cover and an outer edge of the side cover to discharge air from the hybrid fan.

Dependent claims

A head-mounted display (HMD) comprising:

a fan having a center axis extending from a rear side of the HMD to a front side of the HMD, the fan configured to pull air from a rear side of the HMD;
a printed circuit board (PCB) with one or more electronic components;
a heat pipe having an end coupled to the PCB, the heat pipe at least partially surrounding a periphery of the fan and transferring heat away from the PCB;
and
an integrated metal frame onto which the PCB is directly mounted, the integrated metal frame in contact with the heat pipe and configured to function as a heat sink that receives the heat from the heat pipe and dissipates the heat, the integrated metal frame formed with a hole to receive the fan.
