Description

Technical Field

[0001] This utility model relates to the field of precise temperature control and heat recovery technology for high-temperature formation cabinets, and in particular to a cold and heat source recovery and utilization system for high-temperature formation cabinets. Background Technology

[0002] The power supply cabinet and the formation cabinet are two key components of the formation equipment in a lithium battery factory. The normal operation of the formation cabinet requires a stable power supply from the power supply cabinet, and the heat dissipation requirements of the power supply cabinet are closely related to the operating status of the formation cabinet. The greater the operating load of the formation cabinet, the more heat the power supply cabinet generates, and the higher the heat dissipation requirements.

[0003] Currently, in traditional designs, power cabinets are typically placed in ambient temperature workshops, relying on the environment for self-heating. This heat dissipation method is inefficient, resulting in the internal temperature of the power cabinet being higher than the ambient temperature. Meanwhile, the formation cabinet needs to maintain a high-temperature and low-humidity environment. Traditional centralized temperature and humidity control systems suffer from high energy consumption and uneven airflow distribution, making it difficult to guarantee the consistency and stability of the air intake parameters of the formation cabinet, which affects the charging and discharging consistency and quality of the batteries.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1 In this embodiment, a heat and cold source recovery and utilization system for a high-temperature formation cabinet includes a formation cabinet 1 and a power supply cabinet 2 located below the formation cabinet 1. The formation cabinet 1 has a formation chamber 11 and a warm air chamber 12 arranged vertically and vertically. The warm air chamber 12 is equipped with a condenser coil 3 and a blower 4. The power supply cabinet 2 includes a cooling chamber 21, which is equipped with an evaporator coil 5, a compressor 6 and a throttling device 7 respectively connected to both ends of the evaporator coil 5. One end of the condenser coil 3 is connected to the compressor 6 and the other end is connected to the throttling device 7. Compressor 6 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then delivered to the condenser coil 3. There, the refrigerant condenses into a liquid state, releasing heat and raising the temperature in the heated room. The high-temperature, high-pressure liquid refrigerant, under the pressure reduction effect of the throttling device 7, becomes a low-temperature, low-pressure liquid refrigerant, which flows back to the evaporator coil 5. There, it absorbs heat and vaporizes, lowering the temperature in the cooling chamber 21 and simultaneously dehumidifying. The refrigerant continuously circulates through the path: compressor 6 → condenser coil 3 → throttling device 7 → evaporator coil 5 → compressor 6, achieving heat recovery and utilization.

[0021] Furthermore, the formation chamber 11 and the warm air chamber 12 are connected by a diffuser plate 15. Hot air from the warm air chamber 12 enters the formation chamber 11 through the diffuser plate 15. By designing multiple small holes on the diffuser plate 15, the air is dispersed into multiple airflow directions as it passes through these holes, thereby achieving uniform airflow distribution. This diffuser plate 15 effectively utilizes the thermal property of air rising to achieve airflow uniformity and improve the consistency of the battery formation temperature within the chamber.

[0022] Furthermore, the blower 4 is located below the condenser coil 3. The blower 4 draws air in from the warm air chamber 12 and blows it out through the diffuser plate 15, ensuring that the air can reach every corner of the formation chamber 11. This forced air supply method can effectively avoid uneven airflow distribution caused by natural convection.

[0023] Furthermore, the warm air chamber 12 has first ventilation holes 121 on both sides. The air in the warm air chamber 12 is heated by the condenser coil 3 and then sent into the formation chamber 11 through the blower 4 and the diffuser plate 5. In order to maintain the air balance of the system, low-humidity air needs to be introduced into the warm air chamber 12 from the formation workshop. This low-humidity air enters the warm air chamber 12 through the first ventilation holes 121.

[0024] Furthermore, the power cabinet 2 also includes a power cabinet body 22 located on one side of the cooling chamber 21, with second ventilation holes 211 on both sides of the cooling chamber 21. Air in the cooling chamber 21, after being cooled and dehumidified by the evaporator coil 5, enters the power cabinet body 22 through the second ventilation hole 211 on the right side to cool the electronic components. Simultaneously, the high-temperature air in the power cabinet body 22 returns to the cooling chamber 22 through the second ventilation hole 211 on the right side, forming a closed airflow cycle. In addition, the second ventilation hole 211 on the right side introduces low-temperature, low-humidity air from the cooling chamber 21 into the power cabinet body 22, ensuring that the temperature inside the power cabinet body 22 remains within a safe range. The second ventilation hole 211 on the left side serves to circulate air and maintain pressure balance within the cooling chamber 21.

[0025] Furthermore, a water collection tray 8 is provided at the bottom of the cooling chamber 21. The water collection tray 8 is used to collect the condensate generated by the evaporator coil 5 during the dehumidification process. The water collection tray 8 is connected to the water pipe to discharge the collected condensate from the system and prevent water from accumulating in the system.

[0026] Furthermore, a first air duct 9, connected to the cooling chamber 21, is provided above the power cabinet body 22. This first air duct 9 is used to transport the high-temperature, low-humidity air generated after dehumidification and deheating by the evaporator coil 5 to the regeneration heating section 13 of the dehumidifier, where it is used as a regeneration heat source. Similarly, this system is located inside the drying chamber 10, and a second air duct 14 is provided above the drying chamber 10; this second air duct 14 is also connected to the regeneration heating section 13, transporting the high-temperature, low-humidity air inside the drying chamber 10 out for reuse.

[0027] In operation, the condenser coil 3 in the warm air chamber 12 directly heats the ambient temperature and low dew point air in the chemical formation workshop to 45°C via refrigerant. The air is then evenly distributed through the diffuser plate 15 by the blower 4. This ensures that the chemical formation process operates at the optimal temperature of 45°C and that the airflow is more uniform, reducing the impact of local temperature inconsistencies on the chemical formation effect. After the evaporator coil 5 cools and dehumidifies the cooling chamber 21, the cooled air is introduced into the power cabinet body 22 through the second ventilation hole 211 to cool the power equipment. The condensate is collected and discharged through the water collection pan 8. The cooled high-temperature and low-humidity gas is collected through the first air duct 9 and the second air duct 14 for use in the regeneration heating of the rotary drum in the chemical formation workshop.
