HEAT PIPE OPTIMIZATION TEAM THE HEAT PIPE ASSISTED HEAT SINK PROJECT

摘要

The Heat Pipe Assisted Heat Sink (HPAHS) team will be working on solving challenging thermal management problems for a device known as the base transceiver station (BTS); a device used to transfer cell phone calls. This problem was raised due to the high use of cell phone in recent years. According to 2002 Scarborough Research, the number of cell phones in US was 180 million (2/3 of population). Due to this high increase in demand for cell phone usage, Replacement Handset Shipments are projected to increase worldwide from Current 40% of total shipments to almost 85%. This will increase from 211 million in 2002 to 591 million by 2008 (Nokia). Cell phone calls are transferred via a device known as the base transceiver station (BTS). Cell phone companies are increasing the performance of the BTS by adding more electronics. Nokia is increasing the current BTS performance by adding another power amplifier. We will encounter the problem of designing the thermal solution to ensure optimal thermal performance, while meeting customer requirements of cost and manufacturing process.
