Abstract

The application of a liquid thermal-bridge system for spot cooling of a fluorescent lamps inside fixtures is described. A thermal bridging system facilitates the convection of heat away from a small area on the lamp to the fixture housing, where is it dissipated to the plenum or surrounding ambient space. This results in reduced minimum lamp wall temperatures with a corresponding increase in light output and system efficacy. Experimental performance data for a range of ambient temperatures is presented, and the overall feasibility and application of using liquid heat sinks in fixtures are discussed.<>

液体热桥在提高荧光灯具热性能中的应用
介绍了液体热桥系统在荧光灯内点冷却中的应用。热桥接系统促进热量从灯上的一个小区域到灯具外壳的对流,在那里它消散到静压室或周围的环境空间。这导致降低最低灯壁温度与相应的光输出和系统效率的增加。给出了一系列环境温度下的实验性能数据,并讨论了在夹具中使用液体散热器的总体可行性和应用。
