Hello! I have a process I am trying to control and need to cool a round, flat plate - localized temperatures can get as high as 500°C. We currently use a fixture that has cooling water flowing through it, but we believe that as the plate that needs to be cooled gets hot, deformation occurs and there is some surface separation and we aren't getting a proper contact between the cooling fixture and the flat plate and thus not cooling like we need to. We have tried using heat transfer grease, but we still think there is a separation issue. We have been toying with the idea of using Liquid Nitrogen, but I don't have a clue as to even where to start the investigation/research. I am looking for design resources(nozzle design, estimated transfer rates, etc.), ideas, suggestions as to where I might go with this... Please?
Thanks in advance!
