The convection heat transfer coefficient is explored for a new academic laboratory experiment. A cost-effective design is generated with three core principles: 1) Low Cost, 2) Low Maintenance, and 3) Concept Visualization. This is achieved through the following description of the apparatus. The plexiglass chamber has a square base with a designated height. At the bottom of the chamber, there is a rectangular section removed to act as an inlet to the chamber. A high powered mini turbine fan is located at the top of the chamber. The fan acts as the driving force that pulls in the surrounding air from the inlet to generate a flow within the chamber. A hatch is located on the side to allow for interchanging of different test geometries. The geometries being used are 3D printed to components either in the form of a fin (External Flow) or a hollowed channel parallel to the flow (Internal Flow). The components are mounted to the chamber wall with a heater in plate in between. The component are heated until steady state, where the average temperature along the surface is calculated. The velocity, surface temperature, ambient temperature are record through the use of a data acquisition system. The resulting convection coefficients are then determined.
