PRINTED CIRCUIT HEAT EXCHANGERS

In the world of high-performance engineering, the demand for "smaller, stronger, and more efficient" is constant. Whether it’s for clean energy, aerospace, or industrial processing, managing heat is a critical challenge.

 

Enter the Printed Circuit Heat Exchanger (PCHE)—the gold standard in compact thermal management. At the heart of this revolution is Metching, the global leader in manufacturing the precision flow plates that make these advanced systems possible.

​

What is a Printed Circuit Heat Exchanger?

A PCHE is not your traditional "shell and tube" or "plate and frame" heat exchanger. Instead of using bulky pipes or gaskets, it utilizes a sophisticated combination of chemical etching and diffusion bonding.

​

The process is elegant in its complexity:

​

1. Chemical Etching: Complex flow channels are "printed" or etched into metal plates with microscopic precision.

2. Diffusion Bonding: These plates are stacked and subjected to high heat and pressure. The metals join at an atomic level, turning the stack into a single, solid block of metal.

​

The result? A heat exchanger that is up to 85% smaller and lighter than traditional designs, yet capable of withstanding extreme pressures and temperatures.

Metching: Pioneering the Flow Plate Industry

 

Since the 1990s, Metching has been at the forefront of PCHE technology. We don't just manufacture parts; we provide the volume capacity and exceptional channel accuracy that the world’s most demanding industries rely on.

​

Why Metching Leads the Market:

​

• Unmatched Scale: Our production etching plant is one of the largest in the world, capable of supplying etched flow plates up to 1500mm x 600mm in size.

• Versatility: We handle everything from 2.5mm thick plates to ultra-thin foils.

• Prototype to Production: Our process is designed for speed. We can move from a cost-effective prototype to high-volume production faster than any other provider in the market.

​

Material Excellence

 

Different environments require different metals. While 316-grade stainless steel is the industry standard for its durability and heat resistance, Metching’s chemical etching process is compatible with a vast array of materials.

​

For specialized applications, we work with:

​

• Aerospace-grade Aluminum: For when weight is the primary concern.

• Corrosion-Resistant Alloys: For harsh maritime or chemical environments.

• High-Nickel Alloys: For extreme temperature scenarios.

​

A Seamless, One-Stop Solution

 

Building a PCHE requires a bridge between two worlds: chemical etching and diffusion bonding. Metching has spent decades building that bridge.

​

Through longstanding partnerships with global leaders in diffusion bonding technology, we offer a comprehensive one-stop-shop. We ensure that the flow plates we etch are perfectly optimized for the bonding process, resulting in a seamless integration that guarantees structural integrity and thermal performance.
