20130056176 | Heat Exchanger with Controlled Coefficient of Thermal Expansion - The heat exchanger with a controlled coefficient of thermal expansion (CTE) includes a low CTE thermal expansion control member operatively connected to a heat transfer member in order to restrain the lateral thermal expansion of the heat transfer member during use. The thermal expansion control member is placed outside the heat transfer path, so the thermal expansion control member can be made of a low thermal conductivity material without increasing the thermal resistance of the heat exchanger. The CTE of the thermal expansion control member is lower than that of the heat transfer member, so as to constrain lateral thermal expansion of the heat transfer member during operation. The difference between the CTE of the device being cooled and the heat transfer member, i.e. the CTE mismatch, is reduced over conventional heat exchangers by restraining the heat transfer member during operation. | 03-07-2013 |
20110226448 | HEAT EXCHANGER HAVING WINDING CHANNELS - A winding channel heat exchanger includes a heat transfer member having winding channels, a manifold, and a cover plate. The channels' winding design is defined by a non-linear flow axis that may include a plurality of short pitch and small amplitude undulations, which cause the flow to change directions, and may also or alternatively include two or more large amplitude bends that cause the flow to reverse direction. In one embodiment, the undulations have varying amplitudes to increase the heat transfer coefficient along the length of the channel. The winding channels allow a user to customize the pressure drop to promote good flow distribution, to achieve improved heat transfer uniformity, and to improve the heat transfer coefficient. | 09-22-2011 |
20100032147 | HEAT EXCHANGER HAVING WINDING MICRO-CHANNELS - A micro-channel heat exchanger suited for use in large-area cold plates includes a heat transfer member having winding micro-channels, a manifold, and a cover plate. The micro-channels' winding design is defined by a nonlinear flow axis that may include a plurality of short pitch and small amplitude undulations, which cause the flow to change directions, as well as two or more large amplitude bends that cause the flow to reverse direction. In low flow per unit area applications, the winding micro-channels allow a user to customize the pressure drop to promote good flow distribution, to achieve improved heat transfer uniformity, and to enable the pressure drop to remain above the bubble point of the heat transfer structure to prevent gas blockage. The winding micro-channels also improve the heat transfer coefficient. | 02-11-2010 |
