摘要
根据电子设备试验用冷却装置的技术要求,结合电子设备试验的特点,提出最佳的电子设备试验用冷却装置的设计方案。该方案将常规风-水换热和压缩制冷两种工作模式合二为一,综合利用自动控制技术,采用二次循环冷却、压缩机排气旁通调节制冷量和电动三通阀调节供水温度三种方式相结合的方法,使设计的冷却装置不仅可适应多型电子设备的变负荷试验对宽温供水以及精度的需求,而且对减少初投资和降低运行费用具有重要意义。同时该冷却装置采用模块化设计,可以通过组合满足大功率电子设备的试验需求,并可在此基础上进一步实现冷却装置的系列化。
This paper presenes an optimal solution to the system design according to the technical requirements of cooling devices for electronic equipments testing. It integrates air-water-heat-exchange-mode with regular refrigeration-mode innovatively thus ensuring the cooling devices meet the requirement of multi-type electronic equipments testing under different energy load, through utilizing automatic control technique and three advanced technique： secondary cycling cooling, by-pass system of discharge, and water temperature adjustment with electric triple valve. Synchronously modularized design makes it possible to meet the requirement of large-power electronic equipment test through combining several devices. Serialized design based on this device is realizable.
