Thermal management of projection displays

The key requirements constraining the solutions were described. One constraint on the cooling design for most projection display products was cost. This, almost immediately, pointed to an air-cooled solution using conventional fans and heat sinks. Another constraint with a more direct customer impact that couples in with the air-cooled approach was audible noise. A third constraint was that the cooling design for projection displays must accommodate a variety of different types of components. As evident from these design constraints, the cooling solutions for projection displays was confined to conventional air-cooling approaches. The challenge was using the conventional techniques to achieve an efficient design that met all the requirements for the product.
