Copper Micro-Channel Heatsink Research

Sidney · 25th October 2005, 17:02

"Mechanical engineers at Purdue University have new findings offering promise for modifying household refrigeration technology with small devices called "micro-channel heat sinks" that circulate coolant through numerous channels about three times the width of a human hair. The researchers are adapting refrigeration systems by using the micro-channel heat sinks to replace conventional "evaporators" – components in household refrigerators that contain a labyrinth of tubing. As coolant circulates through the tubing, heat is removed from the refrigerator to cool the food inside. The device has been tested with a refrigerant called R134a, which is used in household air conditioners and refrigerators. The micro-channel heat sink is a copper plate containing numerous grooves 231 microns wide – or about three times as wide as a human hair – and 713 microns deep."
