Abstract: A magnetofluid pump device for IGBT heat dissipation and a test method therefor are provided. The magnetofluid pump device uses a liquid metal as a coolant, which can absorb more heat than an ordinary water-cooling device and better dissipate heat for IGBT chips. Temperature and pressure changes in an inlet pipe and an outlet pipe of a magnetofluid pump can be monitored in real time through temperature sensors and pressure sensors, and temperature changes of the IGBT chips can be observed in real time through a thermal imager. The test method for the magnetofluid pump device for IGBT heat dissipation proposed by the present invention is simple and easy to implement. A magnetic fluid can be driven to flow by energizing positive and negative electrodes in the magnetofluid pump under the action of magnetic fields, and water-cooling equipment can dissipate heat for the magnetic fluid in the magnetofluid pump.

Abstract: An online fast processing method for real-time data based on edge computing. In the method, a dynamic online de-noising method is adopted to remove noise contained in speeds to ensure the effectiveness and accuracy of de-noising results; for the displacement integrated online, an efficient method is adopted for dynamic online de-noising to further reduce the effectiveness of drift in the displacement value on final integration results; and under the condition of ensuring the accuracy of an integration method, an integration algorithm is embedded into an edge device to realize fast calculation and analysis of data near a data source and realize dynamic fast integration of online signals based on the edge device, which provides effective references for efficient processing and calculation of data.
