Method for an apparatus for convection cooling using a product label

Disclosed is a method for an apparatus for convection cooling using a product label. Benefits include improved cooling, improved package structural integrity, and improved manufacturing process.

Description

              The disclosed method utilizes an external product label as a heat exchanger for the passive cooling of components inside an electronic system. This technique is particularly useful in consumer products where heat management must typically be undetected by the end user. In this case, a label is a good candidate for hiding the thermal exchange mechanism from the casual observer. This method has been validated in thermal tests of an Internet appliance (IA) for cooling the system hard disk. Results showed notable improvement in hard drive temperatures over systems that encapsulated the cooling elements. The label acts as a heat spreader and hides the internal thermal plate for the hard drive. This method is part of a system solution that is a fan-free IA system design.

              The key elements of the disclosed method include:

•             Conductive materials in direct surface contact

•             Thermally conductive label material attached to internal thermal circuit

•             Thermal adhesives and highly conductive thermal materials

•             High-temperature graphic printing for the label is not required, as the label design must be such that the average user will not experience a “hot” surface (This item is a design constraint, and many solutions for label material, size and shape exist to satisfy it, depending on the system thermal scenario.)

•             A system apparatus comprised of heat-generating internal elements

•             An apparatus that creates a thermal circuit from an internal heat-generating component to an exterior meta...
