The power output of Information and Communications Technology (ICT) is ever increasing resulting in greater heat loads and increased reliability issues in vital electronics components. The problem with current ICT heat sinks is that single phase thermal management strategies have attained their upper threshold in transport capabilities due to the limited cooling capacity of air-cooled heat sinks. Indeed, this proposal's industry partner Alcatel-Lucent Canada, relies on single phase thermal management strategies for its Remote Radio Heads by increasing the size of the devices' heat sinks to match the increasing heat loads. This solution however results in an adverse size and weight to the apparatus which is not desired for their remote ICT devices. The present proposal puts forth the first phase in a heat management strategy which aims to develop a highly effective two-phase thermal system designed to handle the heat loads of ICT devices. A second phase into the viability of this thermal management strategy will be the subject of a future Engage plus application. The motivation for this project is to increase the reliability of ICT components and to reduce overall heat sink size and weight.

信息和通信技术（ICT）的功率输出不断增加， 重要电子元件中的热负荷和增加的可靠性问题。当前ICT热的问题 汇是单相热管理策略已达到其上限阈值在运输 由于风冷散热器的冷却能力有限，事实上，该提案的行业合作伙伴 阿尔卡特朗讯加拿大公司依靠单相热管理策略， 增加设备散热器的尺寸以匹配增加的热负荷。然而，该解决方案导致 其尺寸和重量对设备不利，这对于它们的远程ICT设备是不期望的。 目前的建议提出了第一阶段的热管理战略，其目的是发展一个高度 高效的两相热系统，旨在处理ICT设备的热负荷。进入第二阶段 这种热管理策略的可行性将是未来Engage plus应用的主题。的 该项目的动机是提高ICT组件的可靠性，并减小整体散热器的尺寸 和重量。
