Description

0785616 THERMALLY CONTROLLED CONTAINER UTILIZING CONTOURED FLOW PRIORITY [0001] This application claims priority to U.S. Provisional Pat. App. No. 63/524,765, entitled “Thermally Controlled Air Cargo Container Configured for Temperature Controlled Operation of Frozen to Controlled Room Temperature with Improved Efficiency and Contoured Flow,” filed on July 3, 2023, the disclosure of which is incorporated by reference herein. APPLICATION FIELD [0002] This application relates generally to cold chain or temperature-controlled shipping, and more specifically to cold chain shipping by commercial aircraft. BACKGROUND [0003] Various high value items are shipped, preferably by air freight, within a temperature controlled container. These high value items may include medicines (e.g., vaccines, organic compositions, individually developed treatments, and/or perishable medical material), food (e.g., seafood, spices, meat, yeast, and/or easily perishable edibles), and/or plants (e.g., flowers and/or seeds). For bulk loads, pallet sized loads, and other similarly sized loads, larger insulated shipping containers may regulate cargo temperature as well as include insulating features to minimize loss due to ambient conditions. [0004] Generally, there are two types of shipping containers: (1) active containers and (2) passive containers. Active containers actively control a shipping container’s cargo temperature, and include a control system to sense the temperature of the cargo bay, where a control system directs heating and cooling systems to maintain and correct for temperature deviations. Alternatively, a passive system has no control system and instead uses pre-cooled material for thermal capacitance. Passive systems may incorporate insulation to slow the ambient parasitic temperature effects similar to a common ice cooler. [0005] Air cargo containers and unit load devices (ULDs) attempt to achieve temperature control via heating and cooling systems, e.g., for use on an aircraft. Active stand-alone shipping containers include their own heating and cooling system for a 0785616 cargo bay (interior of the container) without external power or connections. Active stand-alone containers may rely on batteries and a means of thermal conversion. Further, an active stand-alone ULD is limited in performance within the tradeoff of exerted energy toward thermal regulation, the ambient effects of loss, and the on-board stored energy within the batteries. The better the thermal insulation and the more efficient the control system, the longer duration it will perform. [0006] Temperature controlled ULDs’ cargo bay and load regulation may suffer from underserved areas or regions. These underserved areas or regions may be due to initial flow pathways, cargo bay and load geometries, environmental effects, among other causes. These environmental effects may include, for example, ambient effects of a hot wall possibly being exposed to the sun on a hot day, a windward side on a cold day, and/or door seals, etc. Temperature controlled ULDs may create super-heated or super- cooled exposure near the conditioned air outlet or in low air resistance areas and insufficient exposure in farther away areas (e.g., corners or crevasses). It is undesirable for a first portion of cargo to suffer one extreme of exposure and a second portion of cargo to suffer from the other extreme (e.g., frozen in the rear, melted in the front). [0007] As a result, it is desirable for containers that accommodate temperature sensitive cargos to overcome these and other problems.
