Claim of US Patent No. 9,907,201

1. A portable electronic device comprising:
a housing having a top case and a bottom case, the housing carrying:
an electronic component that generates thermal energy during operation of the electronic component;
a heat exchanger thermally coupled to the electronic component, wherein the heat exchanger receives a coolant capable of carrying
at least some of the thermal energy that is generated by the electronic component;

a fan assembly that generates an air flow, wherein the air flow comprises (i) a first air flow that impinges on the heat exchanger
and transports a first amount of the thermal energy through a port located at a first sidewall, and (ii) a second air flow
that transports a second amount of the thermal energy through a gap located between the heat exchanger and a second sidewall,
wherein mixing of the first air flow and the second air flow occurs at the port; and

an air flow duct located between the heat exchanger and the second sidewall, wherein the air flow duct directs a portion of
the second airflow away from an additional component adjacent the second sidewall within the gap.
