Abstract： In this paper, the effective material properties and mechanical behavior of heat exchanger plateswith primary and secondary trapezoidal cormugated structure were theoretically modeled and numericallystudied.First , we derived the two predicted formulae for effective material properties of heat exchangerplates with only primary corrugated structures combining the two existing equivalent approaches and thegeometric dimensions of real heat exchanger cornugated plates.Then we investigated the accuracy and ap-plication range of the two predicted formulae by comparing the cornugated plate's deformation using differ-ent predicted formulae and the simulation results given by a solid mimic model using the commercial AN-SYS software.And then we derived a prediction formula for the heat exchanger plate structure with primaryand secondary corrugations using the series model of composite structures. The influence of the secondary cornugations and off-axis characteristics on the effective properties of the heat exchanger cormugated platestructure are also discussed and displayed.
