a–d Assembled magnetic circuit and associated components. a Photo of the magnetic circuit. b Sample cabin. c The MCSs in each sample cabin. d The MCS with a size of 6.5 × 12 × 1 mm3. e Schematic diagram of the test process of the TMG system. The system consists of a magnetic circuit, a data collector, a control system, cold and hot water pumps, cold and hot water tanks, a recovery tank, pipelines, and valves. Use two K-type thermocouples to connect the data collector to record the temperature change of the water temperature at the left and right sides of the inlet. The coil is connected to the data collector, and the induced voltage generated by the TMG is recorded. f, g Infrared image of TMG. f Cold water flows through the left (lower) side while hot water flows through the right (upper) side of the magnetic circuit. g Hot water flows through the left (lower) side while cold water flows through the right (upper) side of the magnetic circuit. h–m TMG performance test. h The temperature curve of the water and MCS on the left inlet. i, The temperature curve of the water and MCS on the right inlet. j The induced voltage curve generated by the TMG. k The numerical simulation of the induced voltage. l The magnetic flux density B and m, the corresponding dB/dt curve on the left and right sides of the magnetic circuit.
