In this study, the single plate model of the plate heat exchanger is made and the performance of the plate in the presence of the blocks of the separate herringbone plate and plover pattern plate is examined. The aim of the present study is to consider the effect of the plate shape and pitch of the blocks on the overall heat transfer coefficient and frictional pressure drop and to obtain the optimum one. The overall heat transfer coefficient and frictional pressure drop were obtained by measuring temperature and pressure drop between inlet and outlet of the channel, respectively. The results of the separate herringbone plate and plover pattern plate were compared with the herringbone and flat plate.
