Abstract:
A packaging system, comprising:a substantially sealed and insulated housing;support means disposed internally of the housing for supporting equipment;first passive cooling means comprising phase change material disposed internal of the housing for absorbing heat above a first predetermined temperature thereby limiting further increases in temperature internal of the housing;second passive cooling means comprising:heat sink means disposed externally of the housing; andpassive switch means for providing a low thermal resistance path between the interior of the housing and the heat sink means above a second predetermined temperature to effect cooling of the equipment and for providing a high thermal resistance between the interior of the housing and the heat sink means below the second predetermined temperature to thereby preserve heat internal of the housing;an electronic equipment supported by the support means, the electronic equipment having electrical components thermally conductively attached to a substrate, the substrate being thermally conductively attached to a thermally conductive member to form a module and wherein the module is removably thermally conductively attached to the switch means.
