【摘要】：波节管换热器是能显著改善换热器传热性能的新型换热器,以其优秀的传热性能备受换热器设计者青睐。传统换热器手工计算,尤其是换热器的传热计算,包括传热系数计算、传热面积计算和校核计算是一项耗时耗力的复杂过程,而且人工计算容易失误。对传统换热器的设计,已有多款不同的设计软件,但有关波节管换热器传热软件的研制,目前尚未见报道。本文详细介绍了波节管换热器传热设计的基本原理和传热软件研发的一般步骤,用Microsoft Visual Studio 2010编程软件,结合波节管换热器的工艺设计方法,研究开发了波节管换热器传热计算软件系统。将波节管换热器的设计计算由人机对话来实现,主要包括换热系数、换热面积、校核和布管设计等几项工作。结果表明,利用此软件省略了繁杂的手工计算,使波节型换热器的设计快速准确,应用方便。同时,本软件研发过程中,将水-水传热模式和汽-水传热模式集成在同一软件中,设计了波节管换热器无相变传热和有相变传热两种传热形式,扩大了软件的使用范围。本软件在研发过程中设置了一些实用的查询窗口,包括管材导热系数查询窗口、波节管中心距查询窗口等。比如程序设计中的布管窗口,将复杂的布管绘图以程序中的GDI绘图方法绘制在荧屏上,节省了设计者的结构设计时间。程序中的表格和计算书两种导出形式也为设计者的后续设计提供了方便。
[Abstract]:The corrugated tube heat exchanger is a new type of heat exchanger which can improve the heat transfer performance of the heat exchanger significantly. It is favored by the heat exchanger designers for its excellent heat transfer performance. Manual calculation of heat exchanger, especially heat transfer calculation of heat exchanger, including heat transfer coefficient calculation, heat transfer area calculation and check calculation, is a time-consuming and labor-consuming complex process, and manual calculation is easy to make mistakes. There are many different design software for traditional heat exchanger, but the development of heat transfer software for corrugated tube heat exchanger has not been reported. This paper introduces in detail the basic principle of heat transfer design of corrugated tube heat exchanger and the general steps of the development of heat transfer software, using Microsoft Visual Studio 2010 programming software, combined with the process design method of the corrugated tube heat exchanger. A software system for heat transfer calculation of corrugated tube heat exchanger is developed. The design and calculation of corrugated tube heat exchanger are realized by man-machine dialogue, including heat transfer coefficient, heat transfer area, check and pipe layout design, etc. The results show that the complicated manual calculation is omitted by this software, which makes the design of the corrugated heat exchanger fast and accurate, and the application is convenient. At the same time, the water-water heat transfer mode and the steam-water heat transfer mode are integrated into the same software in the course of the software development, and two heat transfer modes, no phase change heat transfer and phase change heat transfer mode, are designed in the corrugated tube heat exchanger, and the application range of the software is expanded. Some practical query windows are set up in the course of the development of the software, including the query window of the thermal conductivity of the pipe, the window of the center distance of the corrugated tube, and so on. For example, the tube window in the program design can be drawn on the screen by using the GDI drawing method in the program, which saves the designer's time of structure design. The two forms of table and calculation in the program also provide convenience for the designer's subsequent design.
