Having read myriad papers/articles/books/reports on thermal management, I feel there is a lot of misunderstanding about what really should drive a sound approach of how to tackle the thermal problems that tend to land on the desk of thermal designers. I also have the feeling that many “how to” articles presented on the Web are just meant to show off the knowledge of the author … [Read more...]
Simplified Formula for Estimating Natural Convection Heat Transfer Coefficient on a Flat Plate
Although most of the emphasis today in the electronics cooling community is devoted to extending forced convection cooling capability, many applications still depend upon natural convection cooling. Basically, natural convection cooling combined with radiation is what results when a fan is not used in the cooling design to move air. Instead, movement of the air is induced by … [Read more...]
Natural convection modeling of heat sinks using web-based tools
Heat transfer in electronic packages is a complex problem involving a network of resistive paths for the various laminated structures, bonding adhesives, lead frames, and attachment mechanisms, such as ball grid arrays. However, despite the multitude of materials and interfaces within an electronic package, the largest thermal resistance, and consequently the controlling … [Read more...]
