Heat exchanger with resin headers and metal body
The patent US12072155B2 describes a heat exchanger featuring a metal body with a flow passage designed for a heating medium. The flow passage extends in a specified direction and is connected to a first header, which includes an inlet or outlet. The body is characterized by distinct faces: a front face, a back face, and two side faces, with the first header bonded to multiple bonding faces on these surfaces. Notably, the first header is constructed from a resin containing fibers, with a significant alignment of the fibers (60% or more) in a consistent direction across its various portions. The design includes specific geometric features, such as curved bonding faces that extend outward, and a flow passage with a unique cross-sectional shape that combines straight and arching elements.
Additionally, the patent outlines the potential for a second header, also made from a resin containing fibers, which serves as the counterpart to the first header. This second header is similarly bonded to the body and features a comparable structure, including cylindrical bodies for the ports. The heat exchanger may also incorporate multiple flow passages, enhancing its functionality. The body can be made from aluminum or an aluminum alloy, and the design emphasizes the importance of the curvature and alignment of the bonding faces and flow passages to optimize performance. Overall, the claims detail a sophisticated heat exchanger design that integrates advanced materials and structural features to improve efficiency and effectiveness in heat transfer applications.
