Example Embodiment
[0026] Example 1
[0027] The invention provides a foamed metal composite phase change material heat storage thermoelectric power generation device, such as figure 1 , figure 2 Shown.
[0028] The outer wall of the high-temperature flue gas carbon steel pipe 1 is equipped with a small partition sealed carbon steel container 2, and the small partition sealed carbon steel container 2 is filled with a foamed metal composite phase change energy storage material 3, which is a foamed metal Cu as a skeleton and a phase change material For KHF 2 , The phase transition temperature is 196℃. The small separated sealed container 2 is closely connected with the hot end of the thermoelectric power generation module 5 through the thermal conductive glue 4, and the cold end of the thermoelectric power generation module 5 is connected with the heat dissipation block 6. Cooling circulating water 7 passes through the radiating block 6, and its outer side is connected with the radiating fin 8. The...
Example Embodiment
[0031] Example 2:
[0032] This embodiment applies the foam metal composite phase change material heat storage temperature difference power generation device provided in Example 1. The difference is that the small partition sealed container 2 uses aluminum alloy material; the small partition sealed aluminum alloy container 2 is filled with foam metal composite The phase change energy storage material 3 is made of foamed metal Al as the framework, the phase change material is AlCl3, the phase change temperature is 192℃; the AlCl3 phase change material accounts for 85% of the total weight; the high temperature flue gas aluminum alloy pipe 1 is equipped with aluminum alloy fins inside 9. The working engineering of Example 2 is the same as that of Example 1.
Example Embodiment
[0033] Example 3:
[0034] This embodiment applies the foam metal composite phase change material heat storage thermoelectric power generation device provided in Example 1. The only difference is that the small partition sealed container 2 uses copper alloy material; the small partition sealed copper alloy container 2 is filled with foam metal composite Phase change energy storage material 3, using foamed metal Cu as the framework, phase change material 50% LiF / 50% LiOH, phase change temperature 427℃; phase change material accounts for 80% of the total weight; high temperature flue gas copper alloy pipe 1 internal assembly There are copper alloy ribs 9. The working engineering of Example 3 is the same as that of Example 1.
