摘要:

本文针对户外电子设备恶劣的工作环境设计了一种空空热交换器散热装置,该装置同时具有智能控制和自诊断功能,可以有效地调节机柜内部温度,并隔绝外部环境潮湿、砂尘和盐雾的影响,保证设备长时间的正常运行,且结构紧凑、维修更换方便。同时,采用了流体网络建模(FNM)技术对其进行仿真和实验验证,结果表明:在-40℃~55℃环境下,该空空热交换器能有效控制机柜于正常的工作温度范围内,显示了该空空热交换器可为户外通讯、电子、电力设备营造良好和可靠的工作环境,具有广阔的应用前景。

Abstract:

This paper presents an airtoair heat exchanger that is designed by taking into account the bad working environment of the open air. The internal cabinet temperature is regulated and the external circumstance is isolated effectively by the present device with the features of intelligent control, selfdiagnosis, compact structure and convenient maintenance. Meanwhile, a flow network model of the entire system is constructed by MacroFlow which is based on the Flow Network Modeling (FNM). Accordingly, longtime operation can be guaranteed and the application of the airtoair heat exchanger has a promising future.

Key words: air-to-air heat exchanger;thermal design;electronics heat dispersion;FNM
