2. Plate-fin heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Plate-fin_heat_exchanger

   Aluminum alloy plate-fin heat exchangers, often referred to as Brazed Aluminum Heat Exchangers, have been used in the aircraft industry for more than 75 years and adopted into the cryogenic air separation industry around the time of the second world war and shortly afterward into cryogenic processes in chemical plants such as Natural Gas ...

3. Air separation - Wikipedia

   en.wikipedia.org/wiki/Air_separation

   To minimize the compression cost the combined condenser/reboiler of the HP/LP columns must operate with a temperature difference of only 1-2 K, requiring plate fin brazed aluminium heat exchangers. Typical oxygen purities range in from 97.5% to 99.5% and influences the maximum recovery of oxygen.

4. Brazing - Wikipedia

   en.wikipedia.org/wiki/Brazing

   One such capability is heat-treating or age-hardening the workpiece while performing a metal-joining process, all in a single furnace thermal cycle. Products that are most commonly vacuum-brazed include aluminum cold plates, plate-fin heat exchangers, and flat tube heat exchangers. [12]

5. Plate heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Plate_heat_exchanger

   As compared to shell and tube heat exchangers, the temperature approach (the smallest difference between the temperatures of the cold and hot streams) in a plate heat exchangers may be as low as 1 °C whereas shell and tube heat exchangers require an approach of 5 °C or more. For the same amount of heat exchanged, the size of the plate heat ...

6. CuproBraze - Wikipedia

   en.wikipedia.org/wiki/CuproBraze

   Brazed copper-brass heat exchangers are also more rugged than soldered copper-brass and alternate materials, including brazed aluminum serpentine. [2] Air pressure drop is a factor of heat exchanger design. A heat exchanger core with a smaller air pressure drops from the front to the back of the core (i.e., from the windward to the leeward side ...

7. Hampson–Linde cycle - Wikipedia

   en.wikipedia.org/wiki/Hampson–Linde_cycle

   The high pressure gas is then cooled by immersing the gas in a cooler environment; the gas loses some of its energy (heat). Linde's patent example gives an example of brine at 10°C. The high pressure gas is further cooled with a countercurrent heat exchanger; the cooler gas leaving the last stage cools the gas going to the last stage.
