Abstract
A cooling system includes means for maintaining electronic control components of a glassware forming machine at a safe operational temperature. A circuit board heat sink is attached to and substantially covers the component mounting surface of a printed circuit board. The circuit board heat sink includes a thermoconductive pad for each component and a metallic panel. Thermoconductive means engage a portion of the circuit board heat sink to transmit heat energy from the components through the heat sink to a coolant manifold. The thermoconductive means includes at least one card guide for frictionally engaging the circuit board and the circuit board heat sink, and a card rack for supporting the card guide. A coolant manifold has a plurality of passages formed therein for the passage of coolant throughout. The manifold is attached to a housing which encloses and is attached to the card rack and receives the heat energy from the components. The coolant fluid removes the heat energy accumulated by the manifold from the cooling system.
