A shell and tube heat exchanger is a durable, versatile device widely used in industrial applications to transfer heat between two fluids without mixing them. It features a cylindrical shell housing a bundle of tubes—often made of stainless steel, copper, or titanium—where one fluid flows through the tubes (tube side) and the other flows around them within the shell (shell side). Key components include tube sheets that secure the tubes and separate the fluids, baffles that guide the shell-side fluid in a zigzag pattern to enhance turbulence and heat transfer, and headers/nozzles for fluid entry and exit, ensuring efficient thermal performance across diverse operating conditions.
Shell and tube heat exchangers have a wide range of applications, a few of which are:
A brazed plate heat exchanger is engineered as a compact, efficient system comprising a stack of corrugated channel plates sandwiched between robust front and rear cover-plate assemblies. These assemblies include sealing plates, blind rings, and customizable cover plates equipped with connections tailored to meet diverse market and application demands, such as HVAC, refrigeration, or industrial processes. During the vacuum-brazing process, a strong joint is formed at every contact point between the base plates and the filler material—typically pure copper or nickel—resulting in a durable structure with two distinct channels or circuits for fluid flow, preventing any mixing of the fluids.
The channel plates feature varying herringbone patterns, which allow precise tuning of hydraulic and thermal characteristics. This flexibility enables brazed plate heat exchangers to maintain consistent pressure drops across both sides, even with differing flow rates, optimizing performance for specific applications. Fluid flow can be configured as co-current (parallel) or counter-current, with options like dual-circuit, two-pass, or dual-over-two-pass designs to suit complex thermal requirements. Standard plate materials include AISI 316 stainless steel, vacuum-brazed with copper or nickel-based fillers for corrosion resistance, while high-molybdenum SMO 254 stainless steel is available for harsh, corrosive environments. This combination of customizable design, material versatility, and high-efficiency heat transfer makes brazed plate heat exchangers ideal for demanding industrial, marine, and energy applications.
