Hybrid Manufacturing Process of Loop Heat Pipe Evaporator

In response to the FY 2022 NASA SBIR Solicitation Topic S06.15 Scope ldquo;Advanced Manufacturing of Loop Heat Pipe Evaporatorrdquo;, Advanced Cooling Technologies, Inc. (ACT) and FormAlloy Technologies, Inc. (FormAlloy) propose to develop a hybrid manufacturing process for loop heat pipe (LHP) evaporator.nbsp; Such a hybrid manufacturing process combines conventional sintering and additive manufacturing (AM) technology.nbsp; The process can retain the ~1-micrometer pore size of the current primary wick while eliminating the knife-edge seal (KES) that may fail under long exposure to thermal cycles and vibrations. In Phase I, ACT and FormAlloy will continue the process optimization, and perform LHP operation demonstration with evaporators fabricated by the proposed hybrid process.
