AI Technical Summary
Existing heat transfer coolers, such as EGR coolers, face challenges in manufacturing complex core geometries without forming support structures, which leads to increased flow resistance, pressure drop, and manufacturing costs due to limitations in additive manufacturing technology.
A core body with interconnected unit cells featuring curved sidewalls and orifices, allowing for thermal energy transfer between fluids without mixing, and utilizing a flexible diaphragm for thermal expansion accommodation, enabling additive manufacturing without support structures and reducing flow resistance.
The solution enhances fluid throughput, reduces manufacturing costs, and increases the useful life of heat transfer apparatuses by accommodating thermal cycling and extreme temperatures, while eliminating the need for sliding interfaces and potential leak paths.
