Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage equipment, and specifically relates to a dehumidification system and an energy storage system. Background Art

[0002] As a device for storing energy, energy storage systems are very common in daily production and life. With the continuous development of secondary batteries, secondary batteries are also widely used in energy storage systems. During the charging and discharging process of secondary batteries, a large amount of heat energy will be generated, which will increase the temperature of the entire energy storage system. Traditional secondary battery energy storage systems usually use air cooling to control the temperature of the secondary batteries during operation. An air inlet is opened on one side of the box of the energy storage system, and an air outlet is opened on the other side. Cold air enters the energy storage system through the air inlet, and then comes into contact with the secondary battery, mixing with the hot air generated when the secondary battery is working, and the heat in the energy storage system is taken away by the air outlet. At this time, there are both cold air generated by the external environment and hot air generated when the secondary battery is working in the energy storage system. In the process of the intersection of cold air and hot air, there will be a phenomenon of mixing of cold and warm air, which will cause the problem of unsatisfactory temperature control effect of the energy storage system.

[0003] To this end, an energy storage system with the announcement number "CN220491991U" includes a box, a cold source, a battery module and a ventilation duct. The cold source, the battery module and the ventilation duct are all arranged inside the box. The side wall of the box is provided with a heat dissipation port, the cold source is provided with an air outlet, and the outer cover of the battery module is provided with a cover, and different side walls of the cover are provided with air inlet holes and heat dissipation holes respectively; one end of the ventilation duct is connected to the air outlet hole on the cold source, and the other end of the ventilation duct is connected to the air inlet hole on the cover. After the cold air generated by the cold source flows out through the air outlet hole, it enters the cover through the ventilation duct and the air inlet hole, and flows out of the cover through the heat dissipation hole, and is discharged from the heat dissipation port of the box. The ventilation duct is arranged inside the box of the energy storage system, providing a separate passage space for the cold air generated by the cold source, avoiding the contact between the cold air and the hot air inside the box, thereby avoiding the phenomenon of condensation water when the cold and hot air meet inside the box.

[0004] However, for the energy storage system, although the air inlet duct is connected with the air inlet and the cold air is introduced into the air inlet space, the function of cold air entering the cover to cool the battery module can be achieved, but there are still the following obvious defects during use: However, the cold air entering the battery module is slow because there is no corresponding water absorption and dehumidification component in the energy storage system, and the cold air flows naturally to dissipate heat, and the cold air containing moisture enters the energy storage battery module. After a long time of cold air dissipation, water droplets will be generated on the surface of the energy storage battery and the connecting circuit, which will cause water ingress, short-circuit damage and poor heat dissipation of the energy storage battery and the connecting circuit.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a dehumidification system, comprising:

[0025] Dehumidification wind box 1, the inner sides of the dehumidification wind box 1 are provided with air inlet fans 2 for allowing external cold air to enter for dehumidification and filtration, the air inlet fans 2 can help control the temperature level of the energy storage battery box 5, by introducing dry air, the air inlet fans 2 can assist the temperature inside the energy storage battery box 5, strengthen the cooling and heat dissipation of the battery modules inside the energy storage battery box 5, the air outlet ends of the air inlet fans 2 are provided with left air inlet duct 3 and right air inlet duct 6 for guiding the cold air into the energy storage device, so that the dry cold air can independently dissipate the internal heat of the energy storage battery box 5 in the energy storage box 4 on both sides of the dehumidification wind box 1, and can speed up the flow of cold air, the energy storage box 4 for wind power energy storage is provided on both sides of the dehumidification wind box 1 for installing the energy storage battery box 5, and can ensure the safety of the energy storage battery in the energy storage system;

[0026] The energy storage battery box 5 is arranged on both sides of the energy storage box body 4 at both ends of the dehumidification wind box 1, which is conducive to independent cooling and heat dissipation of the battery group in the energy storage system by cold air flow, and a cold air channel 9 is formed between the energy storage battery boxes 5 to allow external cold air to enter the energy storage battery box 5, which can enable the dehumidification component in the dehumidification system to dehumidify and dry the cold air to prevent the cold air containing moisture from entering the interior of the energy storage battery box 5. One side of the cold air channel 9 returns the cold air to guide the flow to the entrance of the energy storage battery box 5 and has a wind guide block 7 with a guiding arc surface, which can enable the cold air to fully enter the interior of the energy storage battery box 5 to cool and dissipate the energy storage battery.

[0027] The two sides of the outside of the dehumidification bellows 1 are embedded with air inlet filter plates 8, so that the cold air adsorbed by the air inlet fan 2 passes through the air inlet filter plates 8 to filter out dust and impurities, thereby reducing the entry of dust and impurities. One side of the air inlet filter plate 8 is located at the air inlet port of the air inlet fan 2, which can control the quality of the incoming cold air and ensure the cleanliness of the energy storage battery box 5. Both sides of the external top surface of the dehumidification bellows 1 are provided with activated carbon dehumidification adsorption plates 10 that penetrate into the inside of the dehumidification bellows 1 to adsorb and dehumidify the cold air. The activated carbon in the activated carbon dehumidification adsorption plate 10 has a large number of micropores and a high specific surface area, which can efficiently adsorb water molecules in the air, thereby effectively reducing humidity and keeping the cold air dry. The activated carbon dehumidification adsorption plate 10 does not require frequent maintenance, and only needs to be replaced or regenerated regularly, with low maintenance cost. Adsorption dehumidification uses an adsorbent (such as silica gel or activated carbon) to absorb moisture passing through the cold air, and a disassembly handle is fixed at the middle of the top of the activated carbon dehumidification adsorption plate 10, which is conducive to disassembly, cleaning and recycling.

[0028] The two side walls at both ends of the dehumidification bellows 1 are symmetrically provided with U-shaped positioning plates 11, and one side of the positioning plate 11 is provided with an assembly groove with the same thickness as the activated carbon dehumidification adsorption plate 10. After the activated carbon dehumidification adsorption plate 10 is installed in the dehumidification bellows 1, it is positioned and stuck in the positioning groove of the positioning plate 11, so that the activated carbon dehumidification adsorption plate 10 can be removed from the external top of the dehumidification bellows 1 for replacement or cleaning of moisture generated by dehumidification, so as to facilitate later use.

The air outlet pipe head 13 extends to the inner side of one end of the cold air channel 9. The side of the energy storage battery box 5 in contact with the energy storage box 4 is penetrated with a hot air output mesh plate 14, so that the cold wind drives the heat to be discharged from the hot air output mesh plate 14 to the outside, so that the cold wind cools down and dissipates the energy storage battery box 5. The energy storage battery box 5 is provided with an air inlet mesh plate 15 on one side corresponding to the cold air channel 9. It is conducive to the cold wind entering the energy storage battery box 5.

[0029] In addition, in order to achieve the above-mentioned purpose, the utility model also provides an energy storage system, which includes the above-mentioned dehumidification system.

[0030] Specifically, during use, when the energy storage battery box 5 needs to work, the air inlet fans 2 on both sides of the dehumidification air box 1 are operated to suck in the external cold air through the air inlet filter screen 8, so that the cold air passing through the air inlet filter screen 8 can filter the existing dust and impurities, thereby preventing the dust from entering the energy storage battery box 5 and adhering to the surface of the battery pack to affect the heat dissipation. The filtered cold air passes through the activated carbon dehumidification adsorption plate 10 loaded through the positioning plate 11, so that the moisture and humidity contained in the cold air can be dehumidified and adsorbed, so that the cold air can maintain a certain degree of dryness and enter the right air inlet duct 6 and the left air inlet duct 3, and is blocked by the cold air guiding baffle plate 12, so that the cold air can enter the air outlet pipe head 13 arranged on both sides of the dehumidification air box 1, and at the same time, the cold air enters the air outlet pipe head 13 and flows rapidly. The air moves to the cold air channel 9 in the energy storage boxes 4 on both sides, and the cold air entering the cold air channel 9 enters the interior of the energy storage battery box 5 through the air inlet mesh plate 15. The cold air enters the flow inside the energy storage battery box 5 and drives the heat to flow. The flowing heat is discharged to the outside of the energy storage box 4 through the hot air output mesh plate 14, thereby achieving the heat discharge and the cooling and heat dissipation effect of the cold air entering the battery pack. The adsorbent in the activated carbon dehumidification adsorption plate 10 adsorbs the moisture contained in the cold air, so as to remove the humidity in the cold air and maintain the dryness, thereby making the cold air entering the energy storage battery box 5 effectively cool and dissipate the heat, and there will be no problem of water droplets on the inner wall of the energy storage battery box 5 and the connecting wire causing water inlet short circuit damage, thereby further improving the safety of cold air heat dissipation of the energy storage battery box 5.
