Abstract
An optical transceiver cooling assembly includes stacked cages mounted to a PCB. A heat radiator also is mounted on the PCB. Cooling devices (e.g., heat pipes) are coupled to the heat radiator and at least one of the cages. In some embodiments, the cages may include a divider that extends beyond the cage and is coupled to at least one of the cooling devices outside the cage. In some embodiments, the cooling devices extend into the cage and may be coupled together.
Claims15
An assembly for cooling an optical transceiver, comprising:
- an optical transceiver cage having a first side wall, a second side wall, a back wall, and a vertical divider, the vertical divider extending from the first side wall to the second side wall wherein the vertical divider extends outside the optical transceiver cage beyond at least one of the first side wall and the second side wall;
- a thermally conductive device having a first end and a second end, wherein the first end of the first thermally conductive device is coupled to the vertical divider within the optical transceiver cage, and wherein the thermally conductive device extends through at least one of the first side wall and the second side wall of the optical transceiver cage;
- and
- a heat radiator spaced from the optical transceiver cage, wherein the second end of the thermally conductive device is coupled to the heat radiator.

An assembly for cooling an optical transceiver, comprising:
- an optical transceiver cage having a first side wall, a second side wall, a back wall, and a vertical divider, the vertical divider extending from the back wall parallel to the first side wall and the second side wall, and wherein the vertical divider extends outside the optical transceiver cage beyond the back wall;
- a thermally conductive device having a first end and a second end, wherein the first end of the first thermally conductive device is coupled to the vertical divider within the optical transceiver cage, and wherein the thermally conductive device extends through the back wall of the optical transceiver cage;
- and
- a heat radiator spaced from the optical transceiver cage, wherein the second end of the thermally conductive device is coupled to the heat radiator.
