Abstract The application of diamond material significantly improves the heat dissipation capability liquid cooling microchannels, solving bottleneck problem for highly integrated electronic components and thus promoting development a new generation military equipment. In this study, microchannels with ultra-high flux density were reliably vacuum-brazed by using AgCuTi filler metal in high vacuu...

The International Thermonuclear Experiment Reactor (ITER) Thermal shield (TS) serves as a cryogenic heat exchanger to maintain the thermal stability of ITER superconducting magnet coil, which is critical control plasma during operation device. TS composed long-length 316L stainless steel (SS) and copper brazed joints. In this case, feasible fabrication design for CCS presented, accomplished by ...

Controlled atmosphere brazing (CAB) is a state-of-the-art joining technology associated with high production rates of many products, including microchannel aluminum heat exchangers. The complex designs of highly augmented compact heat transfer surfaces impose very difficult requirements for a brazing process. Regardless of the fact that brazing is a highly developed engineering art, many state-...

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...
