板式热交换器的传热机理:
  板式热交换器传热机理是根据传热机理是根据热力学定律,“热量总是由高温物体自发地传向低温物体,两种流体存在温度差,就必然有热量进行传递”,两种存在温度差的流体在受迫对流传热过程中,由于热传递板表面采用瓦楞波结构优化设计,其热交换率达到92%,即使流体流速在雷诺准数值以下,流体在板片之间的运动亦呈三维运动,促使流体形成剧烈紊动,减少边界层热阻强化传热效率。


The heat transfer mechanism of plate heat exchanger:Plate heat exchanger heat transfer mechanism is based on the mechanism of heat transfer is according to the laws of thermodynamics, the heat is always by high temperature object spontaneously to low temperature, two kinds of fluid temperature difference exists, is bound to have heat transfer ", exist two kinds of temperature difference of fluid in the process of forced convection heat transfer, due to heat transfer plate surface using corrugated structure optimization design, the heat transfer rate of 92%, even if the fluid velocity in the Renault must value the following, fluid movement between plates was also three dimensional motion, prompting form intense turbulent fluid, reduce the boundary layer thermal resistance improved heat transfer efficiency.
