Experimental Study on Insulation of Submerged Phase Change Cooling Deicing Device

The submerged phase change cooling technology has excellent heat transfer performance, can reduce the ground occupation of the ice melting device, and has good economic benefits. The application of immersion phase change cooling technology to the converter valve of the ice melting device will make the valve section in the complex environment of gas-liquid two-phase state, and it is necessary to carry out insulation test on the valve section in the two-phase flow state. This paper provides the method of reliable and stable generation of two-phase flow, summarizes the insulation test items that need to be carried out in the valve section of two-phase flow, and provides the criterion of passing the insulation test.
