[0004] In the process of realizing the present utility model, the inventors found that at least the following problems in the prior art have not been solved. In the above case, when the temperature in the storage box is too high, the temperature detector sends a signal to drive the exhaust fan to start, and then the hot air flows out of the storage box, thereby being able to exhaust heat and cool the storage box. However, during use, the exhaust fan is installed at the top of the storage box, and can only blow air to dissipate heat to the vanadium liquid flow batteries close to the exhaust fan side, while the vanadium liquid flow batteries close to the bottom of the storage box cannot be effectively dissipated, and the heat dissipation effect is limited. Moreover, blowing air to dissipate heat can easily bring external dust into the storage box, affecting the storage environment inside the storage box.
