Patent ID: 7660409

Claim:
A multi-dwelling unit (MDU) module, comprising: a plurality of service units each configured for providing non-telephony service and telephony service to a plurality of service subscribers, wherein each one of said service units includes a passive heat conducting member; a motherboard having each one of said service units connected thereto and configured for interacting with said service units for providing said non-telephony service and telephony service to said service subscribers, wherein the motherboard includes a passive heat conducting member and a thermal plane, with the passive heat conducting member engaged with the thermal plane; at least one passive heat dissipation assembly configured for absorbing and dissipating heat, wherein the passive heat conducting member of each one of said service units and the passive heat conducting member of the motherboard are conductively engaged with said at least one passive heat dissipation assembly, thereby enabling heat generated by said service units and the motherboard to be absorbed by said at least one passive heat dissipation assembly and to be convectively dissipated from said at least one passive heat dissipation assembly; and wherein the motherboard includes a printed circuit substrate having a first side, a second side and a thermal plane and the second side of the printed circuit substrate of the motherboard is adjacent the passive heat dissipating assembly and the passive heat conducting member of the motherboard is comprised by the printed circuit substrate and the passive heat conducting member of the motherboard extends through the printed circuit substrate of the motherboard between the first side and the second side and is engaged with the thermal plane of the motherboard.
