A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.
Manufactured by the ACE photo etching process from Stainless Steel, Aluminium, Titanium, Copper or Inconel©
Photo etching leaves no mechanical or thermal stress, unlike CNC machining, stamping and laser machining, which can compromise planarity (flatness).
The photo etched plates are stacked and diffusion bonded, diffusion brazed or brazed together to make the heat exchanger.
Low set-up costs and fast lead times make etching a go-to process in batch sizes of one to multiple millions.
The tooling for etching is digital, low-cost and can be modified quickly.
No heat or force is used when etching so mechanical properties remain unaltered and parts are free from stresses and burrs.
The tooling for etching is digital, low-cost and can be modified quickly.
Flat blanks etched then diffusion bonded or brazed.
Heat Exchangers are produced as flat plates with precision micro-etched fluid flow channels in either the top or both the top and underside surfaces. This is also known as printed circuit heat exchangers (PCHEs), as the process of manufacture is the same process as printed circuits hence the product name.
Much smaller than shell and tube heat exchangers delivering excellent space and weight benefits, plate heat exchangers can have a pressure capability of 600 bars (9000 psi) while coping with temperatures ranging from cryogenic to 900°C (1650°F). More than two process streams can be incorporated in a single unit and the requirement for piping and valves dramatically reduced.
The association of chemical etching and diffusion bonding processes into a single product allows the use of a wide range of materials, which, subsequently, allows the use of a variety of clean fluids in the heat exchanger (including corrosive ones).
Reaction and mixing can also be incorporated in the plate heat exchanger design, economically increasing functionality in a single unit.
