Summary:
Christie Digital Systems Inc. (Christie) has established a global reputation as the world’s single source manufacturer of a variety of display technologies and solutions for cinema, large audience environments, business presentations, simulation, 3D and virtual reality. The company has a wide global presence that includes manufacturing facilities in Kitchener, Ontario, Canada. The company needed to develop a 450 W projector which uses the same major components as an existing 350 W projector, without overheating the components. This required exploring ways to prevent temperature sensitive parts from overheating under the new power. One of the parts which has overheated in the new projector, is a hollow pipe made of glass, with a reflective coating on the inner surface. The reflective coating has a specified maximum operating temperature of 200 °C. Figure 1shows the hollow pipe’s approximate location in the projector.
Jesse A. Dyck, a co-op student from the University of Waterloo, was asked to investigate alternative components to replace this component.
Learning objectives:
This case study is intended for use in Mechanical Engineering and System Design courses covering topics such as thermodynamics and heat transfer. The main expected learning outcome is to generate a need assessment and develop analytical model for the heat sink design. This case could also be used to analyze and compare features and characteristics of the difference metal heat sink design and apply FEA tools to validate that.
