Thermal management system for portable electronic devices

Abstract

A wearable electronic device is disclosed. The device can include a support structure and an electronic component disposed in or on the support structure. A heat exchanger element can be thermally coupled with the electronic component, the heat exchanger element comprising a fluid inlet port and a fluid outlet port. A first conduit can be fluidly connected to the fluid inlet port of the heat exchanger, the first conduit configured to convey, to the heat exchanger, liquid at a first temperature. A second conduit can be fluidly connected to the fluid outlet port of the heat exchanger, the second conduit configured to convey, away from the heat exchanger, liquid at a second temperature different from the first temperature.
