Abstract
Description
Technical Field
[0001] This utility model relates to the field of combined heat and power technology, and in particular to a combined heat and power supply device for lithium battery split-type high-temperature formation workshops. Background Technology
[0002] A combined cooling and heating system is an energy supply system that integrates cooling and heating functions. Through a unified set of equipment or pipelines, it provides users with cooling and heating simultaneously or at different times, achieving centralized allocation and efficient utilization of energy.
[0003] Traditional high-temperature integrated equipment in lithium battery factories adopts an integrated design, integrating the formation power module and the needle bed reaction area into a relatively closed overall space. It mainly relies on independent cooling and independent heating modes to maintain the environmental conditions required for operation. Both modes have corresponding independent operating systems to maintain the effective operation of the integrated equipment as a whole.
[0004] Traditional lithium battery plants' split-type high-temperature formation equipment cannot effectively utilize waste heat and cold, resulting in significant energy waste during heating and cooling processes. This leads to high overall plant energy consumption, failing to meet the requirements for energy conservation and emission reduction. Traditional equipment relies on numerous air conditioning ducts to handle heating and cooling loads. In narrow areas, the arrangement of these ducts not only occupies space but also greatly increases the difficulty of pipeline laying, affecting the rational utilization of plant space and construction efficiency. Traditional equipment lacks effective temperature regulation devices for the needle bed area, making it difficult to ensure temperature uniformity in this area. Temperature fluctuations or uneven distribution can easily affect battery formation quality, thereby reducing product yield. The refrigerant system of traditional equipment has a significant risk of water leakage. For power cabinet rooms with a large number of electrical equipment and formation needle bed rooms with high dryness requirements, water leakage may affect the normal operation of equipment and the process environment, indicating poor adaptability.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only one system embodiment of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0038] Reference Figures 1-8This utility model provides an embodiment of a combined cooling and heating system for a lithium battery split-type high-temperature formation workshop. The system includes a power cabinet 1, which serves as the core of the entire combined cooling and heating system, responsible for providing continuous and stable power to all equipment within the system and related operating devices in the workshop. During continuous power supply, its internal electrical components generate a large amount of heat due to energy conversion. This heat is not only an important component of the system's heat load but also provides a usable energy foundation for subsequent waste heat recovery, ensuring the power support for the entire workshop's production and system operation. A guide plate 2 is fixedly connected to the top of the power cabinet 1. The guide plate 2, by its own structure, can precisely guide the hot airflow emitted by the power cabinet 1. It can change the natural diffusion path of the hot airflow, making the originally chaotic airflow orderly. To prevent excessive accumulation of hot air around power cabinet 1 and its impact on equipment heat dissipation, and to guide the hot air to the waste heat recovery device or designated emission area, creating favorable conditions for efficient waste heat recovery or reasonable emission of excess heat, a smoke alarm 3 is fixedly connected to the bottom of the deflector plate 2. The smoke alarm 3 constantly monitors the smoke situation in the surrounding environment. When the power cabinet 1 or surrounding equipment causes smoke due to overheating, short circuit, or other faults, it can quickly detect and trigger the alarm mechanism, promptly alerting on-site personnel through sound, light, and other signals, so as to quickly investigate potential hazards and take emergency measures, effectively preventing the occurrence of fire and other safety accidents, and building a solid defense for system and workshop safety. A temperature sensor 4 is fixedly connected to the rear of the smoke alarm 3. The temperature sensor 4 focuses on capturing the temperature changes around and in the area where the power cabinet 1 is located in real time.It continuously transmits the collected temperature information to the system control system as a basis for judging whether the current ambient temperature is suitable. When the temperature exceeds or falls below the set range, it provides data support for the control system to adjust the operating status of relevant equipment, ensuring that the temperature of the entire area is maintained within a reasonable range. The bottom of the power cabinet 1 is equipped with a ventilation opening 5, which is an important channel for air exchange between the inside and outside of the power cabinet 1. On the one hand, it can dissipate some of the heat generated inside the power cabinet 1 during operation to the outside through airflow, reducing the temperature inside the cabinet. On the other hand, it can introduce fresh air from the outside, promote air circulation inside the cabinet, and prevent heat accumulation inside the cabinet from causing overheating of electrical components, thus ensuring the stable operation of the power cabinet 1. The ventilation opening 5 is equipped with a dust filter 6, which acts as a barrier to filter the air entering the power cabinet 1. The system effectively blocks dust, lint, particulate matter, and other impurities from the air, preventing these impurities from adhering to the circuits and components inside the power cabinet 1. This avoids problems such as poor contact and obstructed heat dissipation caused by impurity accumulation, thereby extending the service life of electrical components and maintaining the normal function of the power cabinet 1. A waste heat recovery fan 7 is fixedly connected to the left side of the power cabinet 1. As the power source for the waste heat recovery process, it generates negative pressure suction through its own operation. It can draw in the waste heat air emitted by the power cabinet 1 through a specific path and then deliver it to the subsequent heat exchange equipment, providing power support for the collection and utilization of waste heat, promoting the waste heat to enter the energy conversion process, and improving the comprehensive utilization rate of energy. A fan filter 9 is fixedly connected inside the waste heat recovery fan 7. The fan filter 9 purifies the air containing waste heat that is drawn in.It can filter out dust, fine particles and other impurities in the air, preventing these impurities from entering subsequent equipment with the airflow. This avoids problems such as blockage of internal channels, reduced heat exchange efficiency or component wear, ensuring the normal operation of all equipment in the waste heat recovery system. A plate heat exchanger 10 is fixedly connected to the right side of the waste heat recovery fan 7. The plate heat exchanger 10 is the core equipment for realizing waste heat recovery. Its multiple sets of heat exchange plates increase the heat exchange area. When air containing waste heat flows through it, it can fully transfer heat with the medium on the other side, transferring the waste heat in the air to the medium that needs to be heated, so that the originally wasted heat can be effectively utilized, improving the energy utilization efficiency of the system. A bracket 11 is fixedly connected to the bottom of the plate heat exchanger 10. The bracket 11 mainly plays a supporting and fixing role. It can stably install the plate heat exchanger 10 in the designated position, resist the vibration generated during equipment operation and the slight disturbance of the external environment, and prevent the plate heat exchanger 10 from shifting or shaking. To prevent issues such as loose connections and seal failures, and to ensure the stable operation of the heat exchange process, a needle bed chamber 20 is located on the right side of the plate heat exchanger 10. As a specific functional area within the workshop, the needle bed chamber 20 is the core location for the high-temperature formation of lithium batteries. It integrates various devices and maintains a suitable high-temperature environment through a combined cooling and heating system, providing stable temperature conditions for the lithium battery formation reaction. It is also a key area for heat utilization and temperature control within the system, directly affecting the formation quality of the lithium batteries. An evaporation assembly is fixedly connected to the top of the power cabinet 1, and an axial flow fan 25 is fixedly connected inside the needle bed chamber 20. The axial flow fan 25 generates airflow through rotation, promoting air circulation within the needle bed chamber 20. It can evenly diffuse the heat released by the condenser 21 to all corners of the needle bed chamber 20, avoiding excessively high or low local temperatures and ensuring uniform temperature distribution within the needle bed chamber 20, providing a stable and consistent temperature environment for the high-temperature formation of lithium batteries.
[0039] Reference Figure 2 and Figure 3The evaporation assembly includes an evaporator 12, which, as the core of the evaporation assembly, is a key device for generating cooling capacity in the system. The refrigerant inside absorbs heat from the surrounding environment under low pressure, evaporating from a liquid state to a gaseous state. This phase change process carries away the surrounding heat, thereby lowering the ambient temperature and providing the required cooling capacity to the system, achieving a cooling effect. The evaporator 12 is fixedly connected to the top of the power cabinet 1, and a flow guide grille 13 is fixedly connected to the bottom of the evaporator 12. The flow guide grille 13 guides and distributes airflow through its structure, ensuring that air passes evenly across the surface of the evaporator 12, avoiding excessive or insufficient local airflow, ensuring sufficient contact between the evaporator 12 and the air, improving heat exchange efficiency, and allowing the cooling capacity to be more effectively dissipated into the surrounding environment. A cold storage tank 14 is fixedly connected to the left side of the evaporator 12. The cold storage tank 14 is mainly used to store the cooling capacity generated by the evaporator 12. When the temperature is low, excess cold energy is stored; when the demand for cold energy increases, the stored cold energy is released, which plays a role in regulating the supply and demand of cold energy, ensuring that the system can continuously and stably provide cold energy to the workshop and maintain temperature balance. The cold storage tank 14 is fixedly connected to the outside of the tank insulation layer 15. The tank insulation layer 15 has good heat insulation performance, which can reduce the heat exchange between the cold energy inside the cold storage tank 14 and the external environment, block the external heat from entering the tank, and prevent the cold energy from being lost due to the influence of the ambient temperature, thereby maintaining the low temperature state inside the cold storage tank 14, improving the storage efficiency and storage time of cold energy. The bottom of the cold storage tank 14 is fixedly connected to the tank base 16. The tank base 16 provides stable support for the cold storage tank 14. It can place the cold storage tank 14 stably on the ground or other foundation, preventing the cold storage tank 14 from tipping over or shifting due to unstable placement, protecting the structural integrity of the cold storage tank 14, and ensuring that its normal cold storage function is not affected.
[0040] Reference Figure 4 A rectangular exhaust duct 8 is fixedly connected to the right side of the waste heat recovery fan 7. The rectangular exhaust duct 8 is fixedly connected to the rear of the power cabinet 1. The three can form a dedicated waste heat transport path, which can concentrate the waste heat air emitted by the power cabinet 1 and guide it to the waste heat recovery fan 7, avoiding the waste heat from spreading randomly in the workshop and causing energy waste. At the same time, its rectangular structure is conducive to stabilizing airflow and ensuring that the waste heat can enter the recovery and treatment stage smoothly and efficiently.
[0041] Reference Figure 3 and Figure 6A compressor 17 is fixedly connected to the right side of the evaporator 12. The compressor 17 is the power core of the refrigerant circulation system. Through mechanical compression, it compresses the low-pressure gaseous refrigerant generated by the evaporator 12 into a high-temperature, high-pressure gaseous refrigerant, increasing the energy level of the refrigerant so that it can release more heat in subsequent components, providing power for the entire refrigerant circulation and driving the transfer of cooling and heating. A refrigerant replenishment tank 18 is fixedly connected to the right side of the compressor 17. The refrigerant replenishment tank 18 is used to store spare refrigerant. When the refrigerant quantity decreases due to minor pipeline leaks or other reasons during system operation, it can be used to replenish the system with refrigerant, maintaining the normal circulation of refrigerant within the system and preventing the system from being affected by insufficient refrigerant. To ensure stable operation of the system and enhance cooling or heating performance, a protective cover 19 is fixedly connected to the outside of the compressor 17. This cover provides all-around protection for the compressor 17, preventing collisions and impacts from external objects and preventing dust and moisture from entering and affecting its operation. It also reduces noise generated during compressor operation, creating a more suitable working environment. A condenser 21 is fixedly connected to the rear of the compressor 17. The condenser 21 plays a crucial role in refrigerant condensation and heat release. High-temperature, high-pressure gaseous refrigerant enters the condenser 21 and exchanges heat with the air in the needle bed 20, releasing a large amount of heat and condensing into liquid refrigerant. The released heat maintains the high-temperature environment in the needle bed 20, achieving efficient heat utilization and simultaneously completing the refrigerant's state transition.
[0042] Reference Figure 1 A needle bed cabinet 27 is fixedly connected inside the needle bed chamber 20. The needle bed cabinet 27 is fixedly connected to the outside of the condenser 21. The needle bed cabinet 27 plays a role in fixing and protecting the condenser 21. It can stabilize the condenser 21 in a designated position and prevent it from shifting due to external forces. At the same time, it can guide the heat released by the condenser 21 to diffuse to a specific area inside the needle bed chamber 20, helping to maintain the temperature stability of the needle bed chamber 20 and providing a good environment for the internal equipment and lithium battery formation process.
[0043] Reference Figure 5A throttling valve 22 is fixedly connected to the right side of the condenser 21. The throttling valve 22 is a key regulating component in the refrigerant circulation system. It can throttle and reduce the pressure of the high-pressure liquid refrigerant discharged from the condenser 21, converting it into low-pressure liquid refrigerant. This creates conditions for the refrigerant to evaporate and absorb heat rapidly after entering the evaporator 12. At the same time, by adjusting the degree of throttling, the flow rate of refrigerant entering the evaporator 12 can be controlled, thereby regulating the cooling capacity of the system. A two-stage refrigerant filter 23 is fixedly connected to the right side of the throttling valve 22. The two-stage refrigerant filter 23 adopts a two-stage filtration structure to deeply purify the liquid refrigerant. The first stage filters larger particulate impurities, while the second stage filters finer particles and moisture, more thoroughly removing contaminants from the refrigerant. This prevents these impurities from entering equipment such as the evaporator 12 and causing blockages or damage, ensuring the purity of the refrigerant and improving the reliability of system operation. An explosion-proof solenoid valve 24 is fixedly connected to the right side of the dual-stage refrigerant filter 23. The explosion-proof solenoid valve 24 controls the opening and closing of the valve via electromagnetic signals. During normal operation, it adjusts the refrigerant flow according to system requirements. When the system experiences abnormal pressure, excessive temperature, or other dangerous situations, it can quickly cut off the refrigerant supply to prevent the danger from escalating, providing safety protection and facilitating automated system control. A refrigerant pipeline 26 is fixedly connected inside the needle bed 20. The refrigerant pipeline 26 is a network of channels connecting equipment such as the evaporator 12, compressor 17, and condenser 21. It provides a path for the refrigerant to circulate within the system, ensuring smooth flow between various devices and achieving the transfer of cooling and heating. Its reasonable layout and sealing performance guarantee the continuity and efficiency of refrigerant circulation.
[0044] Working principle: The heat generated by the power cabinet 1 is partially dissipated through the bottom vent 5, impurities are filtered by the dust filter 6, the top guide plate 2 guides the hot airflow, the temperature sensor 4 monitors the temperature, the smoke alarm 3 ensures safety, the waste heat recovery fan 7 draws in waste heat through the rectangular exhaust channel 8, filters it through the fan filter 9, and then sends it to the plate heat exchanger 10 to complete heat exchange and recovery. The evaporator assembly starts, and the evaporator 12 absorbs heat through the guide grille 13, causing the refrigerant to vaporize. The cold storage tank 14 stores the cold energy, and the gaseous refrigerant enters... Compressor 17 compresses the refrigerant into a high-temperature, high-pressure gaseous state. Refrigerant replenishment tank 18 replenishes the refrigerant. The high-temperature, high-pressure refrigerant enters the condenser 21 in the needle bed room 20, where it works with the needle bed cabinet 27 to dissipate heat and condense into a liquid state. Axial flow fan 25 promotes air circulation in the needle bed room 20. The liquid refrigerant is depressurized by throttling valve 22, filtered by dual-stage refrigerant filter 23, and its flow is controlled by explosion-proof solenoid valve 24. It then returns to evaporator 12 through refrigerant pipeline 26 to complete the cycle. The system operates in a reciprocating manner to achieve combined cooling and heating, ensuring stable workshop temperature and improving energy efficiency.
