| Abstract Scope |
Microchannel heat exchanger is an attractive option for the heat transfer of small and micro reactors that require compactness and high efficiency. For gas-cooled reactors the outlet temperature could exceed 750C, posing higher demand for the high temperature performance and structural integrity of heat exchangers.
In this study, we applied the diffusion bonding technique to fabricate a microchannel heat exchanger. The channels were formed by chemical etching a nickel-base alloy plate and the plates were stacked together using diffusion bonding. To evaluate the high temperature behavior of the fabricated heat exchanger, tensile, creep, shear tests were performed to evaluate the strength of the diffusion bonding as compared to the parent alloy. Finally, the experimental data were coupled into a finite element model for the safety analysis of the microchannel heat exchanger. |
