Summary: 
Teledyne Dalsa, headquartered in Canada, is a world leading
high performance digital imaging and semiconductor business,
providing engineering machine vision for a broad range of
applications such as medical, industrial, aerospace, and defense
systems. The Teledyne Dalsa Engineering Division provides
complete engineering solutions for all camera and semiconductor
projects. The division’s projects are diversified in both
application and industry, and can be either custom or standard
depending on the customer’s requirements. Recently, the
engineering division planned to develop a new “Harmony”
camera for industrial image inspection applications. Harmony
design is based on Dalsa’s existing camera and specifically
targets reduced production costs with comparable performance,
scalable component architecture and lower BOM (bill of
materials) cost. The project design focuses on the camera
assembly, specifically reducing fabrication costs of the Harmony
camera body components (H-Section, shown in Figure 1), while
maintaining adequate heat transfer performance. The H-section
is the structural housing to which key electronic components are
attached, and which transfers heat away from these components
via an internal heat sink bridge.
 
Andrew Bogdanis, a 4th year mechanical engineering student from the University of Waterloo, was asked to assess the Harmony camera H-Section parts fabrication process and perform a heat sink thermal analysis to verify conformance with requirements.
