Thermal management for power supply device of a data communication system

A power supply device for a data communication system, the power supply device comprising:

• a busbar including a support panel, a first busbar element extending along a first side of the support panel and a second busbar element extending along a second side of the support panel;
• a shroud surrounding the busbar, the shroud including shroud walls forming a busbar chamber receiving the busbar, the shroud walls including a first side wall, a second side wall, and an end wall opposite a shroud opening configured to receive a power connector of the data communication system;
• a first heat exchanger coupled to the first side wall of the shroud, the first heat exchanger including a first internal portion thermally coupled to the first busbar element, the first heat exchanger including a first external portion exterior of the shroud cooled by convection cooling to dissipate heat from the first busbar element;
• and
• a second heat exchanger coupled to the second side wall of the shroud, the second heat exchanger including a second internal portion thermally coupled to the second busbar element, the second heat exchanger including a second external portion exterior of the shroud cooled by convection cooling to dissipate heat from the second busbar element.

A data communication system comprising:

• a data rack having a rack space;
• equipment trays received in the rack space, the equipment trays including power connectors;
• and
• a power supply device coupled to the power connectors to transmit power between the equipment trays, the power supply device including a shroud coupled to the data rack including shroud walls forming a busbar chamber, the power supply device including a busbar received in the busbar chamber being electrically connected to the power connectors, the busbar including a support panel, a first busbar element extending along a first side of the support panel, and a second busbar element extending along a second side of the support panel, the power supply device including a heat exchanger coupled to the shroud, the heat exchanger including an internal portion thermally coupled to the busbar and an external portion exterior of the shroud cooled by convection cooling to dissipate heat from the busbar.
