Abstract: A hierarchical heat exchanger manifold includes: first and second fluid passages respectively open to an inlet and an outlet in a first level of the heat exchanger manifold; a plurality of first and second fluid passages in a second level of the heat exchanger manifold; and a plurality of first and second fluid passages in a third level of the heat exchanger manifold. A number of the first fluid passages in the third level is greater than a number of the first fluid passages in the second level. Each of the first fluid passages in the second level is in fluid communication with the inlet and at least one of the first fluid passages in the third level, and each of the second fluid passages in the second level is in fluid communication with the outlet and at least one of the second fluid passages in the third level.

Abstract: The present invention relates to a micro-lattice and, more particularly, to an ultra-light micro-lattice and a method for forming the same. The micro-lattice is a cellular material formed of interconnected hollow tubes. The cellular material has a relative density in a range of 0.001% to 0.3%, and a density of 0.9 mg/cc has been demonstrated. The cellular material also has the ability to recover from a deformation exceeding 50% strain.
