[0002] Electrochemical energy storage is a type of energy storage technology, which refers to various secondary battery energy storage. It uses chemical elements as energy storage media, and the charging and discharging process is accompanied by chemical reactions or changes in the energy storage medium. Electrochemical energy storage devices mainly include lead-acid batteries, flow batteries, sodium-sulfur batteries, lithium-ion batteries, etc., and lithium batteries and lead-acid batteries are currently the main ones. A large amount of heat will be generated during power consumption and charging. Electrochemical energy storage devices may be damaged if stored in an overheated environment for a long time, reducing the service life of the device. Therefore, a heat dissipation device is required to cool the electrochemical energy storage device. Electrochemical energy storage devices will generate a large amount of heat during use, and currently the energy storage device is only cooled by exhaust means or coolant. This heat dissipation method cannot effectively and continuously cool down, which will cause the energy storage device to remain in a high temperature state, resulting in its service life being greatly shortened. Therefore, in response to the above problems, it is now necessary to design an electrochemical energy storage device with multiple protections. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0014] Depend on Figure 1 and Figure 2 The utility model includes a packaging shell 1 and a cover plate 2, the cover plate 2 is installed on the top of the packaging shell 1 by screws, a continuous S-shaped cold water pipe 3 is installed on the top of the cover plate 2, an electrochemical energy storage device 4 is installed at equal distances inside the packaging shell 1, two air inlets 101 are symmetrically opened at the lower part of one end of the packaging shell 1, two semiconductor refrigerators 5 are installed at the bottom of the packaging shell 1, the cooling ends of the two semiconductor refrigerators 5 are respectively located inside the two air inlets 101, two suction fans 6 are installed inside the bottom of the packaging shell 1, the two suction fans 6 are respectively connected to the two air inlets 101, two vertical grooves 7 are opened on both sides of the interior of the packaging shell 1, and air supply fans connected to the suction fans 6 are installed at the bottom of the two vertical grooves 7. Tube 8, air outlets 9 are equidistantly provided on the surface of the air supply pipe 8, heat dissipation ports 10 communicating with the upper parts of the two vertical slots 7 are respectively provided on the upper parts of the two sides of the package shell 1, and a protective net 11 is installed in the middle of the heat dissipation port 10; a first heat-conducting copper plate 12 is installed between two adjacent electrochemical energy storage devices 4 inside the package shell 1 and between the electrochemical energy storage device 4 and the inner wall of the package shell 1, a second heat-conducting copper plate 13 in contact with the first heat-conducting copper plate 12 is installed at the bottom of the cover plate 2, and heat dissipation fins 14 are equidistantly installed on the top of the second heat-conducting copper plate 13, and the heat dissipation fins 14 extend to the inside of the continuous S-shaped cold water pipe 3, so that the heat generated by the electrochemical energy storage device 4 can be effectively extracted and effectively cooled;
[0015] One end of the continuous S-shaped cold water pipe 3 is connected to an external cold water pipe, and the other end of the continuous S-shaped cold water pipe 3 is connected to an external water pipe, so that cold water continuously flows in the continuous S-shaped cold water pipe 3; and the heat generated by the electrochemical energy storage device 4 is transferred to the heat dissipation fins 14 through the first heat-conducting copper plate 12 and the second heat-conducting copper plate 13. Since the heat dissipation fins 14 are located inside the continuous S-shaped cold water pipe 3, and there is continuously flowing cold water inside the continuous S-shaped cold water pipe 3, the heat of the heat dissipation fins 14 is taken away by the cold water, thereby playing a role in heat dissipation and cooling.
[0016] A filter 17 is installed at one end of the two air inlets 101, and partitions 15 are fixedly installed at equal distances on both sides of the middle of the two air inlets 101. The middle of the air inlet 101 forms a continuous S-shaped air duct through the partition 15, so that the incoming air can be filtered and cooled; when the external air enters the interior of the air inlet 101 after being filtered by the filter 17, the semiconductor refrigerator 5 is started, so that the air in the continuous S-shaped air duct is effectively cooled and cooled by the semiconductor refrigerator 5, which is beneficial to the subsequent heat dissipation and cooling.
[0017] A dehumidification chamber 16 is provided between the two air inlet ducts 101 and the two suction fans 6, respectively.

As the electrochemical energy storage device 4 is used, heat is generated, and the start of the suction fan 6 will suck the external air into the air inlet duct 101 and cool it down through the semiconductor refrigerator 5. After that, the cold air is adsorbed by the breathable water-washing cotton layer 19, and then the cold air is delivered to the inside of the air supply pipe 8 and blown into the inside of the vertical slot 7 through the air outlet 9. The cold air will cool the heated electrochemical energy storage device 4 and dissipate the heat through the heat dissipation port 10, thereby effectively cooling and dissipating the electrochemical energy storage device 4; and the moisture on the breathable water-washing cotton layer 19 will drip and gather in the water collecting box 102 and be discharged through the leakage hole 20.
