基于SolidWorks的换热器换热效率模拟分析

摘要

换热器是化工、炼油、动力、食品、轻工、原子能、制药、航空及其他许多工业部门广泛使用的一种通用工艺设备。换热器不仅能够合理调节工艺介质的温度以满足工艺流程的需要，也是余热、废热回收利用的有效装置。鉴于换热器在工业生产中的重要作用及其能耗较大的现状，改进和提高换热器的性能及传热效率成为节能降耗的重要途径，将产生重要的经济和社会效益。目前，计算机仿真已经成为一种重要的科研方法，我们可以利用计算机仿真进行换热情况的研究。

本论文首先阐述了换热器的发展特点及国内外的研究情况，其次对流体力学分析从基本理论、处理问题的思路步骤和在软件SolidWorks中的应用进行了阐述，并通过SolidWorks对套管式进行三维建模，利用流体分析工具Flow Simulation插件对换热器进行动态分析。从而得到分析数据，数据主要利用图例从对称边界条件、流体子区域、边界条件、固体材料、体积目标说明换热器的换热情况。

应用SolidWorks软件仿真可以降低研究成本，缩短产品的开发周期，提高工作效率。本文通过对换热器的三维建模，有助于了解换热器的基本结构。对换热器的运动仿真及应用Flow Simulation进行仿真的方法可以为换热器安全性和经济效率的后续研究提供了一些参考。

Analysis of heat exchanger efficiency based on the Solidworks flow simulation

Abstract

Heat exchanger is a universal process equipment of chemical, food, light industry and pharmacy, aerospace, nuclear and many other industrial departments. Heat exchanger not only can be reasonable adjustment process medium temperature to satisfy the need, but also can be process waste heat recovery and utilization device. Since heat exchanger in industrial production have the important role of the status of large energy consumption, improving the efficiency of heat exchanger performance and becoming the important way, energy consumption will produce an important economic and social benefits. At present, the computer simulation has become an important tool, we can use the computer simulation research of stamping safety.

This paper elaborates the characteristics and development of heat exchanger and the research situation of physical analysis, secondly, the convection from basic theory, handling problems and application in software SolidWorks are expounded, and through three-dimensional type of casing SolidWorks modeling, Simulation of fluid Flow analysis tool for heat exchanger for dynamic analysis .To analyze data, using data from the symmetrical boundary conditions, and illustrations area, fluid boundary conditions, the solid material, the volume of the heat exchanger that goal.

Application of SolidWorks software simulation studies to reduce costs, shorten product development cycles, improving work efficiency. Based on the three-dimensional modeling of the heat exchanger, heat exchanger can understand the basic structure of the heat exchanger . The motion simulation of

heat flow and application simulation method of simulation for safety and economic efficiency of heat exchanger follow-up study provides some reference.
