Project Title:
Design, Development, and Investigation of a Multi-Directional Spray Cooling Device.
Project Team:

- Christen Rhodes (Engineering, ‘12)
Project Description:
Spray cooling is one of the promising techniques for removing high heat fluxes from advanced electronics. The evolution of this technology involves the use of experimental techniques to measure heat transfer characteristics and identify key parameters in order to develop methods and correlations to predict the performance. A unique apparatus was investigated that would enable the study of droplet behavior, film thickness, and heat transfer over heated surfaces up to 10 cm2 in size. Strategic research areas for characterizing the spray cooling process at these larger surface sizes were pinpointed. Specifications of associated components for the apparatus, such as pumps and meters, were also identified. Once the overall requirements were selected, a multi-directional spray cooling apparatus was then designed and fabricated. The device provides spray cooling at various spray impact angles and in several device orientations. The spraying assembly is modularized to accommodate different sizes of nozzles or a multi-nozzle array. Heated test blocks incorporating thin aluminum or copper plates are used as the sprayed surfaces.
