Embodiment 1

[0031] Such as figure 1 As shown, the lithium-ion capacitor water-cooled circulation system of the present invention includes a chilled water machine 1 and several water-cooled modules 9 . Each water-cooling module 9 includes a water-cooling plate 5, a group of lithium-ion capacitors, a battery management system (BMS) and other circuit components. The temperature of the water supply is adjusted and controlled. The water-cooled plate 5 adopts a flat tube belt, which goes around back and forth in a serpentine shape, such as figure 2 shown. Lithium-ion capacitors adopt square lithium-ion capacitors, which are regularly arranged into lithium-ion capacitor modules, and the water-cooled plate 5 is detoured between the lithium-ion capacitors, so that at least one large surface of each lithium-ion capacitor is in contact with the water-cooled plate 5 to dissipate heat. Such as Figure 5 shown. The square lithium-ion capacitor is flat as a whole, and the two opposite sides with t...
