Heatric Printed Circuit Health Exchange Construction How we construct our Printed Circuit Heat Exchangers (PCHE): Let’s first look at the construction of a Heatric exchanger. A Heatric exchanger is constructed from flat metal plates with chemically etched fluid flow channels. These fluid flow channels are typically two millimeters wide and one millimeter deep semicircles. The plate layout and flow patterns for the cold and hot sides of the exchanger are designed to suit the particular duty. Each exchanger is uniquely designed to offer an optimized balance between heat transfer, pressure drop, thermal effectiveness, and mechanical requirements. The etched plates are stacked, alternatively cold, hot cold, and hot and diffusion bonded together. Diffusion bonding is a solid-state joining process where, under high temperature and pressure, grain growth takes place at the interface of two metal surfaces in contact with each other. The resulting bond achieves the same mechanical strength as the original material. The diffusion bonding process does not employ braise, flux or gaskets to construct the heat exchanger core. This bonded core is a single metal block with engineered holes running through it. It can then be machined and welded using conventional fabrication techniques. To achieve the performance, several blocks may be required. These individual blocks are then welded to form an exchanger core of the required capacity. To confirm the absence of pressure between each block. An interblock vent is created in the block-to-block weld. Once the core is complete. Headers, including prefabricated nozzles, are attached. These are half cylinders that distribute the fluids into the exchanger core. The exchanger is connected to the customer’s process piping through nozzles. The nozzles can be designed to meet the customer’s individual requirements and typically use flanges, compact hubs or weld preparations. Supports are then attached to the exchanger. The most widely used method is end-type support. These are welded to the ends of the exchanger core. Alternatively, saddle-type supports can be fitted to the lower header of the exchanger. Lifting Lugs are typically located at each end of the exchanger and are suitable for fitting with DSH shackles to attach lifting slings or chains. The lifting points can be incorporated into the end-type supports. Finally, the exchanger can be externally protected by painting or sheathing with a corrosion-resistant material. This sheathing is a sheet metal cladding applied to the outer surface of stainless steel cores for enhanced protection in marine environments, Typical of offshore installations. Heatric exchangers are fabricated mainly from stainless steel but can be made from other materials. Heatric holds both an ASME U stamp and an ASME R stamp and operates an integrated management system, which is certified by Lloyd's Register and which encompasses ISO 9,001, ISO 14,002, and SSAS 18,001.
