Enabling Engineering Breakthroughs that Lead to a Better Tomorrow

Heat Exchanger Flow Plates


The fluids in Heatric’s diffusion bonded heat exchangers are channeled through flow paths chemically etched into metal sheets. These unique flow plates are key in providing the performance of a much larger unit in a considerably smaller footprint.

Each Heatric diffusion-bonded exchanger typically requires 2 plate designs; one for the process fluid flow and one for the cooling medium flow. The flow plates are produced from the material specifically selected according to the duty, process fluids and environment in which the exchanger is required to operate.

The maximum plate size currently available to produce each exchanger core ‘block’ is 600 x 1500mm. If necessary, multiple blocks can then be joined to form the final exchanger core.

Each plate is typically 1.6mm thick into which the specific design of flow channels is then chemically etched creating 2mm diameter semi-circles which, once diffusion-bonded, create the final solid exchanger core.

Flow plate designs

Every flow plate design and resulting exchanger is bespoke created by Heatric’s highly experienced team of chemical and mechanical engineers to match each customer’s detailed duty specifications. The diagram below shows examples of a number of different hot and cold flow plate designs and configurations including counter-flow, multi-pass counter-flow and multi-pass counter-cross-flow.
