Heat conduction bus, particularly for a microprocessor-based computation unit

A heat conduction bus, particularly for a microprocessor-based computation unit, comprising, from one end of the bus to an opposing end:

• a heat-conducting strip provided with a plurality of tabs for solder-connecting to respective connection terminals of electronic components likely to become hot;
• and
• a collector joined to the heat-conducting strip and arranged so as to channel and evacuate thermal energy drained by the plurality of tabs and passing through the strip,
• said heat conduction bus further comprising, at least with respect to ones of the plurality of tabs geometrically closest to the collector, an opening provided in the heat-conducting strip near to said ones of the plurality of tabs, so as to be located interposed between said ones of the plurality of tabs and the collector and to form an obstacle opposing direct routing of the thermal energy between said ones of the plurality of tabs and said collector.
