Abstract
Plate heat exchangers are equipments which can exchange heat by circulating the homogenous or different fluid types with different temperatures without intermixing. These systems are required to be as small as possible and to achieve a high rate of heat transfer. While it is possible to increase the heat transfer to higher values in the improvement studies, high pressure losses arise, which have a negative effect on the heat transfer improvement techniques. These negative effects somewhat limit the use of improvement techniques. In this study, an experimental study was done by designing a new type plate heat exchanger. In the plate heat exchanger developed for this purpose, the springs were placed vertically between the plates to increase the turbulence effect of the fluid. Water at different flow rates was used as fluid on both sides of the heat exchanger. Fluid temperatures and pressure losses were measured in the study. In this context, the effect of springs used in plate heat exchangers on heat transfer and pressure drop were investigated. It was observed that the heat transfer in the spring plate type heat exchanger was higher than that of the non-spring plate type heat exchanger. As a result, heat transfer was improved with the newly designed heat exchanger and a heat exchanger design that is easy to manufacture was realized. Thus, it was found that it is possible to obtain a smaller size heat exchanger in the same capacity by using turbulence generating springs in plate heat exchangers.
