Additively featured plates for heat exchangers

DWPI Title: Forming microchannel heat exchanger core, comprises providing one or more plate substrates, printing microchannel walls on one or more plate substrates, bonding one or more AM featured plates together to form microchannel heat exchanger core, and forming hot and cold inlet and outlet headers
Abstract: Hybrid additive featured plates used to form an overall microchannel heat exchanger and corresponding method of manufacture are disclosed. Various additive manufacturing (AM) techniques may be used to form walls defining microchannel features on a plate substrate. The manufacturing method is a hybrid process in that leverages both additive and conventional manufacturing techniques to minimize both cost and fabrication time.
Use: Method for forming a microchannel heat exchanger core.
Advantage: The method: has low-cost plate material with reliable material properties; and enables more thorough inspection to identify potential defects.
Novelty: Forming a microchannel heat exchanger core, comprising:a. providing one or more plate substrates;b. printing microchannel walls on the one or more plate substrates using an additive manufacturing (AM) process, for producing one or more AM featured plates;c. bonding the one or more AM featured plates together to form the microchannel heat exchanger core, the bonding step adapted to simultaneously join the AM featured plates and densify the microchannel walls;andd. forming hot and cold inlet and outlet headers adjacent to the microchannel walls.
