Abstract

Systems for cooling a virtual reality (VR) headset, including a viewing module that includes a VR display; and a cooling module that includes: a Peltier element having a cold side and a hot side; a blower mounted on the cold side of the Peltier element and configured to draw air across the cold side of the Peltier element and into a first duct; and a fan mounted on the hot side of the Peltier element and configured to draw air from a second duct, where a portion of the first duct and a portion of the second duct are positioned within the viewing module, and where each of the portions includes multiple openings.

Claims (28)

1. A virtual reality (VR) headset, comprising:

a viewing module comprising a VR display; and

a cooling module comprising:

a Peltier element comprising a cold side and a hot side;

a blower mounted on the cold side of the Peltier element and configured to draw air across the cold side of the Peltier element and into a first duct; and

a fan mounted on the hot side of the Peltier element and configured to draw air from a second duct, wherein a portion of the first duct and a portion of the second duct are positioned within the viewing module, and wherein each of the portions comprises a plurality of openings.

2. The VR headset of claim 1 , wherein the first duct and the second duct are coupled to both the cooling module and the viewing module.

3. The VR headset of claim 1 , wherein the portion of the first duct is positioned, within the viewing module, above the portion of the second duct.

4. The VR headset of claim 1 , wherein the cooling module is configured to draw air from the plurality of openings of the first duct into the plurality of openings of the second duct.

5. The VR headset of claim 1 , wherein the plurality of openings of the first duct are smaller than the plurality of openings of the second duct.

6. The VR headset of claim 1 , wherein the VR headset further comprises at least one of a heat sensor and a humidity sensor.

7. The VR headset of claim 1 , wherein the cooling module is configured to cool a user wearing the VR headset.

8. The VR headset of claim 1 , wherein the cooling module is configured to reduce a humidity level within the viewing module of the VR headset.

9. The VR headset of claim 1 , wherein the VR headset further comprises a control element configured to control a fan speed of the blower and the fan.

10. The VR headset of claim 1 , wherein the cooling module is positioned at a rear location of the VR headset.

11. The VR headset of claim 1 , wherein a speed of the blower and the fan is controlled based on a user profile of a user of the VR headset.

12. The VR headset of claim 1 , wherein the cooling module further comprises a drip collector.

13. An apparatus for cooling a virtual reality (VR) headset, the apparatus comprising:

a Peltier element comprising a cold side and a hot side;

a blower mounted on the cold side of the Peltier element and configured to draw air across the cold side of the Peltier element and into a first duct; and

a fan mounted on the hot side of the Peltier element and configured to draw air from a second duct.

14. The apparatus of claim 13 , further comprising a heatsink mounted on the hot side of the Peltier element and positioned between the Peltier element and the fan.

15. The apparatus of claim 13 , wherein the blower and the fan are axially aligned.

16. The apparatus of claim 13 , wherein both the blower and the fan are powered by a single motor.

17. The apparatus of claim 13 , further comprising a plurality of Peltier elements.

18. The apparatus of claim 17 , wherein each of the plurality of Peltier elements is radially positioned around an axis of the fan.

19. The apparatus of claim 13 , further comprising a control element configured to control a fan speed of the blower and the fan.

20. The apparatus of claim 19 , wherein the control element is one of a slider, knob, and switch.
