Why would Apple want to add liquid cooling to the iMac? That was the question on February 10 and it becomes the focus of several new Apple patent applications discovered today at the USPTO. The Mac community, for some reason, got hung up on Apple's old G5 Mac that was designed with large pipes etc, even though the patent clearly indicated it was about a mini-cooling system. To make this point crystal clear - you could download this four page PDF from Asetech that shows just how small cooling systems are getting. In today's patents, Apple mainly focuses on new thermoelectric cooling systems that could be built into a modified MacBook hinge system. Apple's patents attack the problem from different angles making it clear that Apple is searching and researching new ways to keep all of their future devices even cooler. Considering that Steve Jobs tried to change our perception of Apple in January by stating that they were the number one mobile device company in the world, it stands to reason why keeping mobile devices cool physically as well as esthetically is paramount.
