20W Square Liquid Cooling Box
Thread Content
For a 20W cubic liquefied gas cooling box with two-stage throttling, what is the main coolant used to cool the temperature in the middle section?
Currently, the refrigerants used for liquefaction include ethylene, propane, isopentane, isobutane, etc·
Ethylene, propane, isobutane, nitrogen, methane
Propane, ethylene; a higher proportion of ethylene makes it easier to lower the temperature in the middle section
I’m not sure what the original poster means; liquefaction makes use of mixed refrigerants, and depending on the composition of the raw materials, the refrigerant ratios are adjusted accordingly
