Abstract
Plate evaporative water cooler has a wide application prospect in chemical and steel industries.The optimal design of its structure has important guiding significance for engineering application.This paper utilizes MATLAB to simulate the heat and moisture exchange process between cooling water,air,and spray water in a plate evaporative water cooler.By analyzing the influence of structural parameters(length,width,plate spacing and height to width ratio of the cooler)on the cooling performance of plate evaporative water cooler,the influence trend of structural parameters'change on outlet water temperature,outlet air enthalpy and cooling efficiency of evaporative water cooler is obtained.At the same time,the order of structural parameters'influence on performance indexes and the optimal structure sizes of water cooler are obtained.The results show that cooling efficiency of evaporative water cooler decreases with the increase of length,width and air channel plate spacing,and it increases with the increase of plate spacing of hot fluid channel and height to width ratio.The optimal structure sizes of the cooler are as follows when cooling water volume is 300 t/h:the plate spacing of hot fluid channel is 4.10 mm,the air channel plate spacing is 3.75 mm,the length of water cooler is 1.4 m,the width of water cooler is 1.75 m,and the height to width ratio is 0.75.关键词
