A calculation method for counter-current type double-stream coil-wound heat exchanger was presented for heat exchange process. The numerical simulation method was applied to determine the basic physical parameters of double-stream wound bundles. In accordance with methanol-methanol double-stream coil-wound heat exchanger to program and calculate the iterative process. Ccalculation data was analyzed by comparison and a double-stream coil-wound heat exchanger bundle model was built. Studies show that the introduction of numerical simulation method can simplify the tube bundles winding process calculations of double-stream coil-wound heat exchanger. The overall structure design parameters of the heat exchanger can be obtained and be applied to the modeling process. The corresponding three-dimensional physical model can be applied to heat transfer calculation process. It can be programmed to calculate and optimize the overall design of the double-stream heat exchange calculation process.
