Abstract: A heat exchanger for an aircraft includes an inlet plenum housing defining an inlet plenum configured to receive a fluid and an outlet plenum housing defining an outlet plenum configured to discharge the fluid. Furthermore, the heat exchanger includes a core configured to heat or cool a first portion of the fluid, with the core defining a plurality of fluid passages extending from the inlet plenum to the outlet plenum. Moreover, the heat exchanger includes a passive bypass defining a passive bypass flow path fluidly coupled to and extending between the inlet plenum and the outlet plenum. As such, the passive bypass flow path is in parallel with at least a portion of the core such that a second portion of the fluid bypasses at least a portion of the core and flows continuously and unobstructed through the passive bypass flow path to the outlet plenum.

Abstract: A thermal management system includes a housing, and a monolithic core structure disposed within the housing. An outer surface of the core structure defines at least part of a first passageway. An inner surface of the core structure defines at least part of a second passageway. The core structure includes a separator wall that isolates a first flow passing through the first passageway from a second flow passing through the second passageway. The first passageway is in thermal communication with the second passageway. The core structure includes one or more heat exchanger features, or fins, that are positioned within the first passageway, the second passageway, or both the first and second passageways. The core structure may have a compliant segment coupled to two or more walls.

Abstract: A system for mimicking the environmental conditions of a habitat includes an enclosure and a ventilation assembly. A ventilation strip extends horizontally through a sidewall of the enclosure. The ventilation strip includes first and second inner channels separated by an inner fin. A ventilation opening(s) allows communication between the interior of the enclosure and the inner channels. An air fan in fluid communication with the first inner channel provides airflow into the first inner channel to create a low-pressure zone over the ventilation opening, thereby drawing air through the ventilation opening and into the enclosure from the exterior of the enclosure through the second inner channel. In some embodiments, a vertical growing assembly having a mounting panel and a plurality of cells is provided. Each cell is adapted for receiving substrate for growing an organism. A method for training an artificial neural network to control said system is also provided.

Abstract: A heat exchanger that includes an input cavity defined by inlet cavity walls; a heat exchanger portion in fluid communication with the input cavity and defined between a first side and a second side, and wherein a plurality of baffles are positioned within the heat exchanger portion; and an outlet cavity in fluid communication with the heat exchanger portion and defined by outlet cavity walls. The heat exchanger portion comprises: a plurality of first fluid paths defined between the baffles and extending from the input cavity to the outlet cavity, and a plurality of tubes extending through the heat exchanger portion from the first side to the second side. Each tube extends through the baffles so as to define a second fluid path through the heat exchanger portion. Heat exchanger systems are also generally provided, along with methods for cooling a hot fluid input with a heat exchanger.

Abstract: A self contained tropical rainforest vivarium system has an enclosure and a system for creating and maintaining environmental conditions found in a natural tropical rainforest habitat, which at the same time eliminate unnecessary build-up of anaerobic bacteria so as to prevent accumulation of stench and resulting need for frequent disassembly for cleaning and removal of the bacteria and contaminants.
