Copper Micro-Channel Tube for HVAC Applications [ID 06032]



Micro-channel heat exchangers are the latest trend in heating and cooling technologies providing up to 40% increase in efficiency. Most micro-channel heat exchangers on the market today are constructed outof aluminum. An inventor here at Ohio University has found a way to engineer these tubes out of copper.


This invention involves a method to produce a copper micro-channel tube, and effectively create a more long-term and durable heat exchange system for the commercial and residential HVAC industries. Formation of a copper micro-channel tube is an engineering challenge as compared to aluminum micro-channel tubes due to the increased temperatures required. Dr. Kraft has successfully developed an apparatus capable of producing the copper micro-channel exchangers.
