Abstract
A rack for an industrial controller has a metallic top and bottom plate with grooves to receive circuit cards of functional modules. A heat sink on the functional modules has flanges forming parts of the edge of the circuit cards that engage the grooves of the rack to provide a direct path of conduction from the heat sinks to the rack augmenting the cooling of the heat sink normally provided by heat sink fins. The heat sink stands away from the circuit card and has cantilevered flanges returning to the circuit card surface that provide flexure ensuring good contact between the heat sink and the grooves on the rack.
