Water Trap_Spiral Tube

I have the ideas based on the turbulence of H2 flow. I think the more rough surface inside, the more turbulence.At first, the design that you imported is based on how big the velocity passes through the tiny tube inside, I think. It will reduce temperature and make more water condensation.Therefore, I used the spiral tube with smaller diameter (I hope that you can produce this tube - 2.5mm dia). Moreover, I also have an idea to use adiabatic principle to reduce temperature that is to use an electronic valve with very fast on-off. But I cannot design that.
