A main outlet is on a side of the microchannels opposite the cold plate and includes outlet channels with nozzles adjacent the microchannels. The inlet channels are interleaved with the outlet channels. In operation, the main inlet delivers a cooling fluid to the cold plate microchannels via the inlet channels and nozzles, and the main outlet receives the cooling fluid from the microchannels via the outlet channels and nozzles. This configuration provides a cooling fluid distribution pattern for efficient cooling of the electronics.Type: ApplicationFiled: February 18, 2022Publication date: April 18, 2024Inventors: Qihong Nie, Steven D.
