Tube bundle is a core heat transfer component in shell-and-tube coolers, consisting of multiple tubes arranged in a bundle within a shell to facilitate efficient thermal exchange between fluids.
A tube bundle is the primary heat transfer assembly in shell-and-tube coolers, comprising an array of parallel tubes secured within tube sheets and often supported by baffles. It enables thermal energy transfer between two separate fluid streams—one flowing through the tubes (tube-side fluid) and the other around the tubes within the shell (shell-side fluid). The design optimizes surface area for heat exchange while maintaining structural integrity under operational pressures and temperatures.

这些分值是采购评估维度示例,不代表真实客户评分、具体国家买家反馈或实时询盘。
Baffles direct shell-side fluid flow across the tubes, increasing turbulence and heat transfer efficiency while supporting tubes to prevent vibration.
Cleaning methods include mechanical rodding, high-pressure water jetting, chemical cleaning, and brush systems, depending on fouling type and tube material.
Stainless steel (316), titanium, or cupronickel tubes are preferred for high corrosion resistance in aggressive chemical or marine applications.
