Abstract: A method that includes receiving an indication at a modular electronic system of initiation of online removal for a module removably inserted into a slot of the modular electronic system, increasing a fan speed at the modular electronic system before the module is removed, monitoring an internal temperature at the modular electronic system, and providing an indication that the module is ready for removal upon reaching a specified cooling state at the modular electronic system based on the temperature monitoring. A panel on an adjacent module is opened and extends into the slot upon removal of the module to substantially block airflow bypass from the slot and maintain cooling within the modular electronic system. An apparatus and logic are also disclosed herein.

Abstract: In one embodiment, an apparatus includes an optical module comprising a first end for insertion into a network device and a second end extending from the network device when the optical module is inserted into the network device, and a thermal protective layer extending over a portion of the second end of the optical module, the thermal protective layer preventing direct contact with an external surface of the optical module during removal of the optical module from the network device. The thermal protective layer exposes a portion of the external surface of the second end of the optical module to allow heat to be released from the external surface of the optical module.

Abstract: An electronic package (200) comprises a substrate (201), a first carrier layer arrangement (211) adapted to dissipate heat from at least one chip (217) mounted thereon, and a heat exchanger (221) mounted on the first carrier layer arrangement. The first carrier layer arrangement comprises at least one internal microchannel (213), which is fluidically interconnected with the heat exchanger (221) though an inlet (215) and an outlet (219). The heat exchange further comprises a pump (223) controlling fluid flow through the microchannel (213). The package may further comprise a stack of carrier layer arrangements (211), each of which may have one or more chips (217) mounted thereon.

Abstract: The invention relates to heat transfer apparatus for cooling electronic components. There is a continuously increasing demand for compact electronic systems such as portable laptop computers and thirst for high processing power, leading to high heat generated by components residing within these systems. These electronic systems have to be cooled due to their fixed operating temperature ranges. Operating an electronic component beyond its rated operating temperature range will damage electronic components. Instead of conventionally utilising a bigger fan, a smaller sized solution is required for cooling an electronic component contained in a compact electronic system, for example a notebook computer. A heat transfer apparatus includes a heat carrier for conveying heat away from the electronic system into a radiator for dissipation. The radiator is placed into a cooler for directing air through the radiator and expelling heated air, cooling the radiator in the process.

Abstract: Method and apparatus for fluid-based cooling of heat-generating devices are disclosed. A heat-generating device is mounted on a carrier. The heat-generating device is spatially displaced from the surface of the carrier, thereby forming a channel. The heat-generating device and the carrier are enclosed in an enclosure having an inlet and an outlet. A substantially electrically non-conductive cooling fluid for introduction into the enclosure and into the channel and expulsion from the enclosure and for extracting heat from and thereby cooling the heat-generating device and the carrier.

Abstract: A chip scale package (CSP) comprises a flip chip and chip carrier with features to enhance its electrical and thermal performance. The flip chip connects to the chip carrier through alternating signal and ground connections. Top layer routing on the chip carrier substantially maintains ground-based guard isolation between neighboring signal lines. The arrangement of inter-layer vias and bottom layer traces also maintains the isolation for flip chip signals routed to the bottom layer of the chip carrier, where they are available for interconnection with a primary circuit board via solder balls or the like. The bottom layer further includes a centralized ground plane. Special thermal vias extend from the top layer into this bottom layer ground plane. Dedicated solder ball connections for the ground plane provide a ground path between the flip chip and the primary circuit with very low electrical and thermal impedances.
