Heat exchange enhanced module shell

Abstract

To provide a heat exchange enhancement module shell that can be effectively transmitted by a heat sink in a fitting connector or a cage for a pluggable transceiver module.SOLUTION: A pluggable transceiver module 102 contains: an upper shell 112; and a lower shell 114. The upper shell contains a flat inner surface, and a concave-like area formed on the flat inner surface. The module 102 also contains: a PCB 120; a semiconductor chip 122 that is mounted onto the PCB 120; and a heat spreader that is fixed into the concave area between the upper shell 112 and the semiconductor chip 122. The heat spreader can use a heat pipe, a vapor chamber, or a related thermal expansion structure. The heat spreader helps a heat transmission from the semiconductor chip 122 over an expander area of the upper shell 112 of the module 102, and a heat can be effectively transmitted by the heat sink 170.SELECTED DRAWING: Figure 4
