Plate-Fin Heat Exchangers for Compact, Lightweight Heat Transfer

Lytron’s aluminum heat exchangers offer superior heat transfer. They are vacuum-brazed in an environmentally controlled room for maximum cleanliness, quality, and reliability. With our numerically controlled vacuum brazing process and robust fixture designs, we can ensure complete metallurgical bonding between the fins and the separator plates or flat tubes. This guarantees ruggedness and leak-free operation. Lytron operates several vacuum brazing ovens, including one that can braze parts up to 10 feet (3.05 m) long and 3 feet 2 inches (0.97 m) wide.

All of our aluminum, vacuum-brazed, plate-fin heat exchangers are custom-designed, as every requirement is unique. Plate-fin heat exchangers are widely used in aerospace, military, and other high performance applications because they offer excellent thermal transfer capacity combined with small size and weight. Plate-fin heat exchangers can be designed for use with any combination of gas, liquid, and two-phase fluids. We carefully select the number of plate and fin layers, the size of the plates and fin, and the type of fin for optimum performance. Manifold ducting and mounting brackets are welded in place as specified, and any required paint or coating (including MilSpec) can be added.
