In the past, in this matured heat exchanger, the plate element was used to handle highly viscous flows, such as when cooling large engines. Due to its high viscosity, the fluid supplied into the space between the plates from the flow holes formed at the separation between the plates should be dispersed throughout the effective heat transfer section of the plate. In addition, there was a tendency to exhibit uneven flow without being able to disperse uniformly over the entire width of the ripening surface. That is, the fluid flowing out of the flow hole into the inter-plate space gradually decreases in flow velocity as it moves away from the flow hole, but if the viscosity of the fluid is high, the fluid flows in the width direction of the flow. The flow velocity deviations are particularly pronounced

It is easy to do this, and the width of the main part of the flow is narrow and apparently produces dead space. Therefore, the apparent flow velocity is high and the pressure loss is increased, and the heat transfer rate is reduced due to the dead space, and the heat transfer coefficient is reduced.
