摘　　要：以螺旋角25°为例,研究了泄流槽式螺旋折流板换热器传热系数与压降的变化,并给出了泄流槽螺式旋折流板换热器的传热系数与压降相关的计算公式。该结果可为系统仿真和泄流槽式螺旋折流板换热器的设计计算提供借鉴。Taking the helical angle of 25° for example, an investigation is done for the variation of the heat transfer coefficient and pressure drop in draw - off pan spiral baffled heat exchangers. Some calculations of coefficient of heat transfer and pressure drop are given. These calculations provide helpful reference for system simulation and design.
