摘要
为保证有效散热,同时防止有害、潮湿的气体及粉尘等进入,将热虹吸管均热器用于通用电子设备舱,对不同热流功率(800～1 200 W)和不同环境温度(39～53℃)下热虹吸管均热器的散热特性进行试验研究.结果表明,热虹吸管均热器散热性能良好,除风机外无需任何附加动力消耗;不同热流功率、不同环境温度下,舱内外气流温差低于20℃时,热虹吸管均热器均能使舱内的气流温度不超过65℃;电子设备舱内外气流温差在11～17℃,适合内外温差为15℃左右的散热场合;热虹吸管均热器能效比(energy efficiency ratio,EER)为普通空调器的2～3倍,而成本为普通空调器的1/3～1/2,运行可靠性高.
The heat can be effectively dissipated and the harmful humid gas and dust can be isolated using a thermosyphon spreader in a general sealed electric cabin. The heat radiation performance of the thermosyphon spreader is experimentally investigated under different heat fluxes （800 - 1 200 W） and different environmental temperatures （39 -53℃ ）. Experimental results show that the heat radiation performance of the thermosyphon spreader is good, and there is no other power consumption except for fans. When the temperature difference between the inside and outside of the cabin is less than 20℃ , the air temperature in the cabin is not more than 65℃ for different heat fluxes and environmental temperatures using the thermosyphon spreader. The temperature difference between the inside and outside of the sealed cabin is kept in the range of 11 - 17℃ , which shows that the thermosyphon spreader is suitable for the situations with about 15 ℃ temperature difference between the inside and outside air. In addition, the thermosyphon spreader has high reliability, the energy efficiency ratio （EER） of the thermosyphon spreader is 2 - 3 times as much as that of the conventional air-conditioner, and the cost is 1/3 - 1/2 as much as that of the conventional air-conditioner.
