Abstract
The cooling of electronic modules on a circuit board is improved by the use of heat sinks comprising a plurality of longitudinal fins projecting from the modules. Individual tubes communicating with an air plenum fit around and part way along each heat sink. Air drawn from or forced into the plenum causes air flow within the tubes and along the fins to cool them and the modules to which they are attached.
