AI Technical Summary

Technical Problem

In the traditional heat exchanger development process, simulation calculation results do not match the actual operating conditions and cannot accurately reflect the impact of flow path layout on heat exchange effect, thus rendering the simulation calculation results worthless.

Method used

A simulation calculation method for heat exchanger flow rate is adopted. By establishing a flow path representation method and creating a process array, all flow paths are represented as two-dimensional arrays. The method considers flow path bifurcation and merging, simulates the flow distribution in the actual operation process, and simplifies the simulation calculation program logic.

Benefits of technology

It improves the accuracy and efficiency of simulation calculations, reduces the waste of prototype manufacturing and experimental resources, shortens the development cycle, and simplifies calculation time.

Abstract

This invention provides a simulation calculation method, computer device, and readable storage medium for heat exchanger flow rate. The simulation calculation method includes establishing a flow path representation method for the heat exchanger, which includes: Step 1, numbering the heat exchange tubes arranged in m rows and n columns, starting with the heat exchange tube in the first column of the first row, which is numbered 1#, the heat exchange tube in the first column of the second row is numbered (n+1)#, and so on, until the heat exchange tube in the nth column of the mth row is numbered Nr#, the inlet manifold is numbered 0#, and the outlet manifold is numbered (Nr+1)#; Step 2, creating a flow array, representing all flow paths as a two-dimensional array, where each row of the two-dimensional array represents the flow of one refrigerant, and filling the array with the tube numbers of each heat exchange tube as elements according to a preset sorting rule. This simulation calculation method can improve the accuracy of simulation calculations, simplify the logic of simulation calculation programs, and shorten calculation time.
