冻融离心模型试验装置的研发在国内尚处于起步阶段。装置根据半导体单元材料的Peltier效应(帕尔贴效应)设计了安装于双层结构冻融模型箱的热交换系统,实现了离心场下的冻融温变模拟。针对离心机设备无外接冷却水的问题,采用在离心机转臂上设置了由水箱、水泵和风冷散热器组成的自循环水冷却系统,利用离心机旋转时转臂与周围空气速度差产生的高速气流带走自循环水的热量,实现了无外接水源情况下的冻融离心试验。冻融离心试验结果表明,该试验装置满足试验需求。
Freeze-thaw centrifuge model test device research and development in China is still in its infancy. The device is designed according to the Peltier effect (Peltier effect) of the semiconductor element material, and the heat exchange system installed in the double-layer freeze-thaw model box is designed to realize the freeze-thaw temperature change simulation under the centrifugal field. Centrifuge equipment for external cooling water problems, the use of the centrifuge arm set up by the water tank, water pump and air-cooled radiator composed of self-circulating water cooling system, the use of centrifuge rotation arm and ambient air speed difference Of the high-speed airflow away from the heat of the circulating water to achieve the case of no external water freeze-thaw centrifuge test. Freeze-thaw centrifugation test results show that the test device to meet the test requirements.
