Titanium Alloy Plate-Fin Heat Exchanger Core

This stacked metal assembly consists of multiple thin plates with guide fins, integrated via vacuum brazing or diffusion welding to form an internal network of交错 fluid channels. The top cover plate features four circular interface ports and two locating pins, enabling precise alignment and sealed connections with external piping systems. The compact structure offers a large heat exchange surface area, making it common in automotive intercoolers, construction machinery oil coolers, and industrial compressed air cooling systems.

The manufacturing core lies in controlling the alignment precision of stacked thin plates and managing thermal deformation during welding to ensure unobstructed internal channels and pressure resistance meeting operational requirements. The center-to-center tolerance of interface ports and the positional accuracy of locating pins directly impact assembly sealing and require strict control. Meanwhile, the consistency of fin formation determines fluid flow dynamics and heat exchange efficiency, relying heavily on mold precision and stable welding parameters.

Leveraging our comprehensive capabilities in precision machining and specialized welding, we offer full-cycle services from single-piece prototyping to mass production. For structures involving complex internal cavities and multi-port fittings, we recommend providing 2D/3D drawings that specify material grades (e.g., 3003 aluminum alloy), interface dimensional tolerances, and pressure testing standards. We will evaluate costs and lead times based on weld inspection requirements, airtightness testing standards, and surface treatment processes (such as cleaning and passivation).
