摘　　要：本文采用数值模拟软件FLUENT对宽流道板式换热器进行建模,拟合出相关传热准则方程和欧拉方程。使用三项指标为评价标准,经过数据处理得出以下结论:再生水侧运行流速为1.4 m/s左右三项指标最优。提高中介水侧入口温度,可以获得更好的净可用能获比。降低中介水侧入口温度,可以获得更好的可用能流率和可用能耗比。The numerical simulation software FLUENT was applied on a wide flow channel plate heat exchanger modeling,fitting out the relevant transfer rule equation and Euler equations.Using three indicators for the evaluation,after data processing it gets the following conclusions： when the velocity of recycled water side about 1.4 m/s,the three indicators is best; improving the intermediary water inlet temperature,it can get a better net available energy ratio;reducing the intermediary water inlet temperature,it can get a better available energy flow rate and available energy ratio.
