Coil length and heat exchange area.
Thread Content
Common method: use a 1:1 scale drawing, measure the distance between the diagonal coils, determine the circumference, and calculate the heat exchange area. Do any of you have a formula for this?
Aren’t those just calculation formulas? I haven’t seen anything else yet.
The calculation of the heat exchange area of a coiled tube heat exchanger involves multiplying the perimeter of each coil by the number of coils, which gives the total length of the tubes. Then calculate the total area of the tubes. You might be thinking that the coil diameter is inaccurate, and a margin can be added after calculation. We all calculate it this way.
The calculation of the heat exchange area of a coiled tube heat exchanger involves multiplying the perimeter of each coil by the number of coils, which gives the total length of the tubes. Just multiply the heat exchange area per meter of tube by one. The heat exchange area of coiled tubes, including their length, isn’t entirely precise; rounding it off will do. That’s how we do it in our unit. How about you all? ? ? Looking forward to everyone's replies! ! !
Detailed and accurate calculation formulas are available in the refrigeration design manual
The calculation of the heat exchange area for spiral coiled tubes can refer to the relevant calculation formulas for compression springs in the \"Mechanical Design Handbook\"...
