DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
(16)
(17) In another embodiment, a supplemental cooling system 180 may be configured as a portable cooling pad upon which a portable information handling system 100 may mate by resting on the on the supplemental cooling system 180 without interconnects or connectors 137 to receive supplemental cooling air from supplemental cooling system 180, e.g., with optional visual indexing to assist a user in properly orienting the portable information handling system 100 on the supplemental cooling system 180 to receive supplemental cooling air from the supplemental cooling system 180 as described further herein and/or with an optional USB connection or other type power input port of the portable information handling system 100 configured to be coupled to a power output port (e.g., USB) of the portable information handling system 100.
(18) Each of portable information handling systems 100a and 100b have a chassis enclosure 149 (e.g., outer notebook plastic and/or metal case that surrounds the notebook computer electrical components) with air inlet opening 161 in the chassis enclosure 149 to allow cooling air to be drawn into and circulated through the chassis enclosure 149 by the internal notebook cooling fan/s 159 for dissipating or otherwise transferring heat from heat-producing components 191, e.g., via a heat sink that is thermally coupled to heat-producing components 191 such as one or more processing device/s like CPU, GPU, power supply unit/s, etc.). It will be understood that multiple inlet vents 161 and outlet vents 136 may be defined at different locations within chassis enclosure 149, and/or that one or more internal notebook cooling fans 159 may be provided adjacent an inlet opening 161 and/or an outlet vent 136. Moreover, one or more internal cooling fans 159 may be optionally mounted to directly direct cooling air onto a heat sink/s within chassis enclosure 149. Other components of a portable information handling system 100 may include hinged display lid 125 and keyboard 145.
(19) In the embodiment of
(20) In one embodiment, the supplemental cooling air may be cooled to a temperature that is less than the available external ambient temperature air that surrounds the supplemental cooling system 180 and the chassis enclosure 149 of the portable information handling system 100, and in one exemplary embodiment that is at least 10° F. cooler than the available ambient temperature air incoming through the cooling system air inlet 193, and alternatively that is from about 10° F. to about 30° F. cooler than the available ambient temperature air incoming through the cooling system air inlet 193. At the same time, hot side cooling fan 278 circulates ambient temperature air that is drawn in at cooling system air inlet 193 across hot side heat sink 281 and out hot air outlet 207 to exhaust heat generated by chilling system 175. Further information on chilling dock configurations may be found in U.S. patent application Ser. No. 14/965,186 filed Dec. 10, 2015, which is incorporated herein by reference in its entirety for all purposes.
(21) It will be understood that the particular combination of chilling system components illustrated in

A power switch 138 may be present to allow a user to turn power PSU 164 on and off. In one exemplary embodiment, the all or part of the supplemental cooling air path internal to the supplemental cooling system 180 may be thermally isolated (e.g., using thermal insulation material such as fiberglass insulation or foam) to increase or maximize efficiency of cooled air transport to the air inlets 161 of a portable information handing system 100.

(27) In one embodiment, a user may remove an existing lid 155 from cooling system chassis 181, and then manually move cooling air supply conduit/s 197 between the collapsed and extended positions as appropriate when no lid 155 is installed, before manually attaching the supplemental cooling air supply outlet/s 177 in fixed aligned position relative to lid openings 163 of a given lid 155 and then installing and fastening the given lid 155 to the top 222 of cooling system chassis 181. In the embodiment of
(28) Although two different cooling positions (and corresponding lids 155a and 155b) are illustrated, it will be understood that cooling air supply conduits 197 of this embodiment are adjustable to fit infinite different locations and configurations of lid openings 163 that themselves correspond to different air inlet locations of respective different portable information handling systems. Thus, in one embodiment, it is possible that a user may choose a given lid 155 to fit a corresponding portable information handling system (e.g., such as a given size and/or configuration of notebook or laptop computer) from more than two different available lids 155 that have different respective lid opening configurations that are designed to fit different air inlet openings of different portable information handling systems. This advantageously allows a given single cooling system configuration to be used to effectively cool multiple different types of information handling system configurations, and to allow a given single supplemental cooling system 180 to be reconfigured with different lids as needed to operably fit different configurations of portable information handling systems. Moreover, it will be understood that a supplemental cooling system 180 may be provided with as few as one repositionable cooling air supply conduit 197 and corresponding attached cooling air supply outlet 177, or more than two repositionable cooling air supply conduits 197 and corresponding attached cooling air supply outlets 177. Further, it is possible in another embodiment that a supplemental cooling system 180 may be provided with multiple supplemental cooling air supply sources 133 that are each attached to provide supplemental cooling air to at least one repositionable cooling air supply conduit 197 and corresponding attached cooling air supply outlet 177 that is separate and different from a repositionable cooling air supply conduit 197 and corresponding cooling air supply outlet 177 that is attached to receive supplemental cooling air from a different one of the multiple supplemental cooling air supply sources 133.
