Xiaobai asks: Regarding the air separation aluminum plate-fin subcooler, what reasonable flow rates should be maintained at the inlets and outlets of each flow stream?

For air separation aluminum plate-fin subcoolers, what should be the appropriate range of inlet and outlet flow velocities for each stream? Heat flow: Nitrogen, contaminated nitrogen. Cold streams: oxygen-enriched liquid air, liquid nitrogen. Which parameter in EDR should be adjusted to control the flow rate? Is it the inlet and outlet connection diameter?
It is related to the flow cross-sectional area; the total flow area is inversely proportional to the flow velocity. With a constant flow rate, the larger the flow cross-sectional area, the lower the flow velocity. For example, using higher fins, or if the flow occurs in a certain direction and entry occurs from the side, increasing the length of the flow guidance area helps.
