This report discusses the design problem of developing an air-based cooling system for an infantry soldier. The background explores the different designs that already exist as well as specific parts and materials that will be essential to the design process. Currently, liquid-based cooling systems are the most explored types of cooling devices. However, there are specific downsides to this type of cooling device. As opposed to an air-based system, water requires more energy to be cooled, and therefore more battery power. The liquid-based system is also relatively bulky and heavy due to battery size and the water that runs through the system. With air-based cooling systems, efficient cooling is possible. An air-based cooling system was tested in a laboratory and field environment. In a humid environment, a desiccant attachment can improve the cooling device’s effectiveness. The cooling design effectively reduces the wearer’s core body temperature through evaporative cooling. The design evaporates a significant amount of sweat from wearer’s back and torso. While the prototype can be improved, evaporative cooling is an effective cooling solution for Soldiers.
