通过对管壳式热交换器壳侧流动的流型、流阻及其传热特性的系统研究， 得出高效冷却器的最佳参数： 最佳螺旋角为４０°， 多孔介质的最佳孔隙率为０－９８５。在此基础上研制了适于液压锚杆钻机使用的高效冷却器
Through the systematic study on flow pattern, flow resistance and heat transfer characteristics of shell and tube heat exchanger shell, the optimum parameters of high efficiency cooler are obtained: the best helix angle is 40 °, the best porosity of porous media The rate is 0-985. Based on this, an efficient cooler suitable for hydraulic anchor rig is developed
