摘要
热带地区气温高、太阳辐射强,使得野外遥测设备机箱内部温度升高,较高的环境温度对遥测站设备的可靠性及功能和寿命都会产生不利影响。在常规遥测机箱的基础上改良设计带隔热层和通风窗的机箱,利用自然通风散热,不仅有效阻挡太阳光的直射,还可增加机箱内的空气流动,降低野外机箱内部温度,机箱内遥测设备工作在较好的工作环境中。应用实践表明改良设计的机箱完全可以降低机箱内温度,可以在高温地区使用。
High temperature and strong solar radiation in tropical area always lead to temperature increase within the cabinet, which could exert adverse effects on stability, functions and service life of equipment inside. Added heat insulation layer and ventilation window can reduce strong sunlight, increase heat divergence and airflow within the cabinet in such a way to decrease the temperature within the cabinet. In addition, this newly designed cabinet is proved to be able to bring down temperature inside and can be widely used in hot areas.
