Claim 0:
1. A thermal management system for a sealed communication module having an onboard card with at least one electronic component, the thermal management system comprising: a first thermal pathway thermally coupled to the card and configured to transport heat from an upper surface of the card toward a transfer area spaced laterally apart from the upper surface; a second thermal pathway thermally coupled to the first thermal pathway in the transfer area and configured to disperse the heat in a vertical plane spaced laterally apart from the transfer area; and a third thermal pathway thermally coupled to the first thermal pathway in the transfer area and configured to disperse the heat in a horizontal plane spaced vertically apart from the transfer area; and the first thermal pathway comprises: a first heat spreader having a first surface attached to the upper surface of the card and a second surface opposite the first surface; an insulative layer at least partially covering the second surface of the first heat spreader, wherein the insulative layer at least partially blocks heat from dispersing out from an insulated portion of the second surface; a thermal pad attached to a portion of the second surface of the first heat spreader away from the insulative layer; one or more heat pipes extending a distance in a horizontal direction from the thermal pad to the transfer area, each of the one or more heat pipes having a first end portion in thermal communication with the thermal pad and a second end portion opposite the first end portion disperses the heat to a vertical plane which at least partially overlaps with a side wall of a housing; and a second heat spreader having a first portion in thermal communication with the thermal pad with the thermal pad between the first portion and the second surface of the first heat spreader, and a second portion opposite the first portion and coupled to the one or more heat pipe, wherein the second heat spreader at least partially covers an upper surface of the one or more heat pipes.
