How to calculate a coiled tube heat exchanger?
Thread Content
Dear friends, we currently have N2 at 450C and would like to cool it down to 35C. A coiled tube heat exchanger will be used: the N2 flows through the coiled tubes, which are immersed in flowing water (the water enters at 25C and exits at 35C). How to determine the heat exchange area of a coiled tube heat exchanger? Is there a convenient way?
The total heat exchanged, Q, is calculated based on the heat exchange conditions; then, using the formula S=Q/(K·△tm), s can be determined. This is just my opinion – please disregard any inaccuracies
The key question is how to estimate or calculate K?
For the calculation of this k value, I think one can refer to the vaporizers used for the vaporization of liquid chlorine (of the coil type), which operate in flowing hot water
