Their experimental system, which flushes a refrigerant through tiny channels cut into chips, is intended for the high-power electronics found in radar and advanced weapons systems such as lasers, said Issam Mudawar, a mechanical engineering professor at Purdue.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.wired.com/dynamic/stories/T/TEC_AIR_CONDITIONED_CHIPS?SITE=WIRE&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2008-07-16-07-20-15"><P class="ap-story-p">Mudawar, who's leading the research, said the new cooling system should be able to cool chips that produce more than 1,000 watts of heat for about every half-inch square of circuitry.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.wired.com/dynamic/stories/T/TEC_AIR_CONDITIONED_CHIPS?SITE=WIRE&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2008-07-16-07-20-15"><P class="ap-story-p">"Basically what we're doing is opening the window of opportunity in terms of heat dissipation, so that chip developers can make more aggressive chips, more demanding chips," Mudawar said.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.wired.com/dynamic/stories/T/TEC_AIR_CONDITIONED_CHIPS?SITE=WIRE&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2008-07-16-07-20-15">The new cooling system uses tiny parallel grooves called microchannels cut in a chip's surface and covered with a metal plate</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;"> </td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/CCCBF441-8810-404B-8C3D-0A11E831663D/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
