The stacked arrangement of multiple plates allows for a large surface area within a relatively small footprint. ♦ Compact Design: Plate heat exchangers are known for their compact and space-saving design. However, the fluids flow in opposite directions in counterflow, enhancing the overall heat transfer efficiency. Similarly, the hot and cold fluids flow in the same direction, entering the heat exchanger at one end and exiting at the other. ♦ Flow Arrangements: Plate heat exchangers can operate in different flow arrangements, including parallel and counterflow. The turbulence generated by the plate design facilitates efficient heat transfer by minimizing the boundary layer thickness and maximizing the contact between the fluids and the plates. The hot fluid transfers its thermal energy to the plate, then conducts it to the cold liquid on the opposite side. ♦ Heat Transfer: As the fluids flow on either side of the plates, heat is exchanged through the plate material. Secondly, they increase the effective surface area of the plates in the plate heat exchanger, allowing for more significant heat transfer. Firstly, they create turbulence in the fluid flow, promoting better mixing and enhancing heat transfer efficiency. ♦ Plate Design: The plates in a plate heat exchanger design have corrugations or chevron patterns. These fluids flow on opposite sides of the plates, creating a counterflow or parallel flow arrangement. ♦ Fluid Flow: The two fluids, typically hot and cold, enter the heat exchanger through separate inlet ports.
Here’s a more detailed explanation of the process: The calculator is applicable for co-current, counter-current and mixed flow heat exchangers with no phase change in either the hot stream or cold stream where the stream heat capacities can be taken as constant through the exchanger.A plate heat exchanger’s working principle involves transferring heat between two fluids by utilizing a series of corrugated plates. The calculator determines the heat transfer area required for a heat exchanger, the heat exchanger duty, the cold stream flow rate and the mean temperature difference including correction factors. Heat Exchanger Sizing Calculator Guide Show Instructions Heat exchanger duty, cold stream flow rate and mean temperature difference are also determined by the calculator. The calculator can be used for co-current, counter-current or mixed flow heat exchangers. This calculator is used to calculate the heat transfer area required for a heat exchanger.
