Heat exchange storage tank for all-vanadium redox flow battery system

The utility model discloses a heat exchange storage tank for an all-vanadium redox flow battery system. The device comprises a tank body, short plates are fixedly connected to the upper portions of the left side and the right side of the tank body, sliding grooves are machined in the left side and the right side of the tank body, an adjusting mechanism is installed at the bottoms of the two shortplates, the adjusting mechanism comprises a threaded rod, a sleeve plate, a round wheel, a protruding plate, a pipeline and a grip, and the top of the threaded rod is rotationally connected with the bottoms of the short plates. The threaded rod of the adjusting mechanism rotates to drive the sleeve plate to move up and down; the position change of the pipeline is realized; cooling tank, the problem that the internal interlayer is broken due to cooling and heating is solved; cold water and an electrolytic solution are prevented from being mixed, waste is prevented, the cost is reduced, meanwhile, danger after mixing is
