Abstract
A repeater case for high density subscriber lines includes a repeater base and a repeater housing forming a sealed enclosure and having interior walls. A plurality of module slots receive HDSL-4 circuit board modules. A heat conductive material in the housing contacts HDSL-4 modules in the slots and the housing to form a heat escape path to ambient. The HDSL-4 modules are cooled through thermal conductivity with thermally conductive contact with the interior wall of the repeater housing. The heat conductive material is not required for structural support of the modules or their electrical functioning.
Claims23
A repeater case for high density subscriber lines comprising:
- a repeater base;
- a repeater housing forming a sealed enclosure with the base and having interior walls;
- a plurality of module slots configured to receive HDSL-4 circuit board modules;
- a heat conductive material in the housing sized and positioned to contact both the HDSL-4 circuit board modules and the housing to form a heat escape path from the modules to ambient, the heat conductive material attached to an interior wall of a lid of the repeater housing, the heat conductive material not being required for structural support of the modules or their electrical functioning,
- wherein the HDSL-4 circuit board modules are cooled through thermal conductivity with thermally conductive contact with the interior wall of the repeater housing to the ambient outside of the repeater case.
A repeater case for high density subscriber lines comprising:
- a repeater base;
- a repeater housing made of a high temperature plastic forming a sealed enclosure with the base and having interior walls and including a lid, the repeater base, repeater housing and lid being sealably connectable;
- a plurality of module slots in the housing configured to receive HDSL-4 circuit board modules;
- a cable inlet to the repeater base to receive the high density subscriber lines;
- a circuit board card made of phenolic material and connected to the cable inlet;
- connectors on the circuit board made of a high temperature plastic for mounting the HDSL-4 circuit boards modules;
- a heat conductive material
- having an exterior layer of metallic foil on the top and bottom of the thermally conductive material,
- being attached to an interior wall of the lid of the repeater housing, and
- sized to come in contact with the HDSL-4 circuit boards modules and become compressed when the repeater base and the repeater housing are closed, thereby thermally interconnecting the HDSL-4 circuit board modules and the lid to form a heat escape path from the modules to ambient through the heat conductive material.
A method of dissipating thermal energy from high-density subscriber lines comprising:
- opening a repeater case;
- installing HDSL-4 circuit board modules within the plurality of module slots within the base of the repeater case and mounting the HDSL-4 circuit board modules to connectors, thereby creating electrical connectivity with the high density subscriber lines through the cable inlet of the base of the repeater case;
- closing and sealing the repeater housing with a lid having a layer of thermally conductive material, thereby creating compressive contact between the HDSL-4 circuit board modules and the thermally conductive material;
- operating the high density subscriber lines thereby generating heat within the repeater case;
- and
- conducting heat from the HDSL-4 circuit board modules through the thermally conductive layer of the repeater housing lid to the outside environment.
A method of converting a repeater case so as to dissipate thermal energy from high-density subscriber lines comprising:
- providing a repeater case including a base, a housing HDSL modules in the base and a lid;
- and
- installing a thermally conductive material in the lid sized so as to come into contact with the tops of the HDSL modules mounted in the repeater case when the lid is mounted on the case.
