Wearable device with heat transfer pathway
First Claim
1. A wearable device comprising:
- an eyewear body configured for wearing by a user to hold one or more optical elements mounted on the eyewear body within a field of view of the user;
onboard electronic components carried by the eyewear body at a first portion of the eyewear body and comprising a heat source that generates heat during electrically powered operation thereof;
a thermal coupling disposed at a second portion of the eyewear body; and
an elongate heat transfer device disposed within the eyewear body and thermally coupled to the heat source and the thermal coupling and extending lengthwise between the heat source and the thermal coupling to transfer heat from the heat source to the thermal coupling;
wherein the heat transfer device comprises a core wire configured to form part of a structural framework for at least part of the eyewear body.

Abstract
A wearable device is disclosed according to one embodiment. The wearable device can include an eyewear body, onboard electronic components, a thermal coupling and a heat transfer device. The eyewear body can be configured for wearing by a user to hold one or more optical elements mounted on the eyewear body within a field of view of the user. The onboard electronic components can be carried by the eyewear body at a first portion of the eyewear body and can comprise a heat source that generates heat during electrically powered operation thereof. The thermal coupling can be thermally coupled to the heat transfer device at a second portion of the eyewear body. The elongate heat transfer device can be disposed within the eyewear body and can be thermally coupled to the heat source and the thermal coupling. The heat transfer device can extend lengthwise between the heat source and the thermal coupling to transfer heat from the heat source to the thermal coupling.
