Abstract
The present invention relates to the field of heat exchange technology, specifically to a composite process and system for producing a profiled microchannel plate heat exchanger. This process integrates selective laser melting additive manufacturing with micro electrical discharge machining to create microchannel plate heat exchangers featuring large aspect ratio flow channels and closed profile section flow channels. It enables the fabrication of channels with various cross-sections, such as circular and rectangular, as well as hollow closed profile section flow channels, including micro circular and square holes. The process allows for high-precision machining of microchannels with any aspect ratio. Heat exchangers produced using this composite process can endure extreme high temperatures and pressures, offering superior environmental benefits and contamination-free performance compared to conventional microchannel heat exchangers.
