散热器用户热动态模型的创建及应用

Creation and application of thermal dynamic model for radiator users

基于传热学机理,建立了散热器及供暖房间的传热平衡模型,编制算法导入Cyber Sim仿真平台对模型进行测试,将测试结果与前人的研究成果进行对比,仿真模型运行结果符合实际规律。通过模型运行模拟供水流量、温度对散热器散热量及供暖房间室内温度的影响,结果表明,低温热水供暖时,供水温度相同,通过增大流量并不能明显提高散热器的散热效率。

Based on the principles of heat transfer,a heat transfer balance model for radiators and heating rooms is established. An algorithm is compiled and imported into the CyberSim simulation platform to test the model. The test results are compared with previous research results. The simulation model running results are in line with the actual law. The effect of water supply flow and temperature on the heat dissipation of the radiator and the indoor temperature of the heating room was simulated by running the model. The results show that when heating in low temperature hot water,the water supply temperature is the same,and the heat dissipation efficiency of the radiator cannot be significantly improved by increasing the flow rate.
