Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a heat recovery system. Background Technology

[0002] Power batteries are batteries used to provide electricity and are widely used in electric vehicles, energy storage systems, and other devices that require high power output. Compared to traditional small electronic batteries, power batteries have higher capacity and power output, enabling them to support longer operating times.

[0003] Power batteries typically use an aluminum casing structure. In the battery aluminum casing manufacturing line, after the aluminum casing is stretched into a finished product, it undergoes a cleaning process. The cleaning machine needs to have its water changed regularly, and the cleaning operation requires a high water temperature, which needs to be maintained between 50°C and 70°C. After adding room temperature water to the cleaning machine, the water tank undergoes a heating process. The aluminum casing can only be cleaned after the water reaches the required temperature. Heating room temperature water in the tank takes a long time, typically 5 hours. Therefore, the long waiting time for water changes in the aluminum casing cleaning machine during battery aluminum casing manufacturing affects the cleaning efficiency. Utility Model Content

[0005] A heat recovery system is applicable to a battery aluminum shell manufacturing production line. The battery aluminum shell manufacturing production line is equipped with an air compressor, which is connected to a heat medium pipeline assembly. The heat medium pipeline assembly is connected to a heat exchanger. The heat medium circulates in the air compressor, the heat medium pipeline assembly, and the heat exchanger to provide heat to the heat exchanger. The heat exchanger is used to heat the room-temperature water delivered to the cleaning machine.

[0006] Preferably, the heat medium pipeline assembly includes a heat medium inlet pipeline and a heat medium outlet pipeline. The two ends of the heat medium inlet pipeline are respectively connected to the oil outlet of the air compressor and the oil inlet of the heat exchanger, and the two ends of the heat medium outlet pipeline are respectively connected to the oil inlet of the air compressor and the oil outlet of the heat exchanger.

[0015] The beneficial effects of this utility model are: In this heat recovery system, the heat transfer medium is heated in the air compressor and then enters the heat exchanger through the heat transfer medium assembly. The heat exchanger transfers the heat provided by the heat transfer medium to the room-temperature water delivered to the cleaning machine, thus heating the water.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0019] like Figure 1 As shown, this utility model proposes a heat recovery system suitable for battery aluminum casing manufacturing production lines, which include an air compressor 1. The air compressor 1 provides compressed air for the entire production line, and compressed air plays a crucial role in multiple stages. Compressed air is used in pneumatic tools, cleaning, cooling, spraying, mold cleaning, and automated equipment within the production line; therefore, the air compressor 1 is used very frequently.

[0020] Specifically, in the aluminum casing manufacturing process, many precision machining steps such as drilling, milling, cutting, and punching require pneumatic tools. Using pneumatic tools improves work efficiency and ensures machining accuracy. Air compressor 1 provides power to the pneumatic tools. Compressed air can be used to remove dust, metal shavings, oil, and other impurities from the aluminum casing surface, ensuring a smooth and defect-free product surface. Air compressor 1 provides high-pressure airflow for cleaning the workpiece surface and equipment. In aluminum casing manufacturing, some processes such as milling, stamping, and welding generate a large amount of heat. Using compressed air for cooling effectively prevents equipment overheating and maintains product precision. Battery aluminum casings also require anti-corrosion or decorative coating treatments. Through the spraying system, the airflow provided by air compressor 1 ensures uniform coating distribution, improving appearance and durability. Air compressor 1 provides sufficient compressed air for the spraying system. Furthermore, in stamping, casting, and other processes, compressed air is also used to clean residues from the molds, ensuring smooth mold operation and preventing workpiece jamming. In this process, air compressor 1 can be used for mold cleaning and auxiliary equipment operation. In some automated equipment, such as automatic handling, automatic assembly and clamping operations, pneumatic systems are required. Air compressor 1 can provide precise power to these devices, making the production process more automated and reducing human intervention.

[0021] This heat recovery system can recover the heat generated by the air compressor 1 during operation.

[0022] Specifically, air compressor 1 is connected to a heat medium pipeline assembly, which in turn is connected to a heat exchanger 2. The heat medium circulates within air compressor 1, the heat medium pipeline assembly, and the heat exchanger 2 to provide heat to the heat exchanger 2, thereby heating and delivering room-temperature water to the cleaning machine.

[0023] The heat transfer medium includes, but is not limited to, hot oil and hot water. In this embodiment, hot oil is used as the heat transfer medium. Hot oil includes, but is not limited to, mineral oil, synthetic oil, silicone oil, and organic kerosene, and the specific type is selected according to actual needs.

[0024] The heat transfer medium piping assembly includes a heat transfer medium inlet pipe 4 and a heat transfer medium outlet pipe 5. The two ends of the heat transfer medium inlet pipe 4 are connected to the oil outlet of the air compressor 1 and the oil inlet of the heat exchanger 2, respectively. The two ends of the heat transfer medium outlet pipe 5 are connected to the oil inlet of the air compressor 1 and the oil outlet of the heat exchanger 2, respectively.

[0025] In this embodiment, hot oil is heated in the air compressor 1 to form high-temperature oil vapor. The high-temperature oil vapor enters the heat exchanger 2 through the heat medium inlet pipe 4. The high-temperature oil vapor flows through one side of the heat transfer wall of the heat exchanger 2, and the heat is conducted through its solid wall surface. From the other side of the heat transfer wall, the heat is transferred to the room-temperature water flowing through the heat exchanger 2 through convection. After passing through the heat exchanger 2, the high-temperature oil vapor is cooled and then output from the heat medium outlet pipe 5 back to the air compressor 1, forming a heat medium circulation loop.

[0026] Specifically, a hot water storage tank 3 is installed on one side of the heat exchanger 2. The hot water storage tank 3 has two inlet ends and two outlet ends, and each inlet end and each outlet end is connected to a different water supply pipeline. The water supply pipeline includes an inlet pipeline 6, a municipal water pipeline 10, an outlet pipeline 7, and a water supply pipeline 9.

[0027] Furthermore, one inlet of the hot water storage tank 3 is connected to the municipal water pipe 10, and the other inlet is connected to the inlet pipe 6. One end of the inlet pipe 6 is connected to the outlet of the heat exchanger 2. A water supply valve 11 is installed on the municipal water pipe 10.

[0028] One outlet of the hot water storage tank 3 is connected to the outlet pipe 7, and the other outlet is connected to the supply pipe 9. One end of the outlet pipe 7 is connected to the inlet of the heat exchanger 2. One end of the supply pipe 9 is connected to the inlet of the cleaning machine.

[0029] In this embodiment, the water supply valve 11 is opened, allowing external municipal water to enter the hot water storage tank 3 through the municipal water pipe 10 until the hot water storage tank 3 is full of room temperature water. The room temperature water in the hot water storage tank 3 flows from the outlet pipe 7 into the heat exchanger 2, where the heat exchanger 2 heats the room temperature water. After the room temperature water temperature rises to the required water temperature, it flows from the inlet pipe 6 into the hot water storage tank 3 for storage. When the cleaning machine needs to change the water, the hot water (heated room temperature water) in the hot water storage tank 3 is directly used as the water source and supplied to the cleaning machine. The hot water in the hot water storage tank 3 flows into the cleaning machine through the water supply pipe 9. The use of the air compressor 1 heat recovery mechanism can reduce the heating time of the water in the cleaning machine's water tank, improve the cleaning efficiency of the cleaning machine, and also realize the recovery of the heat generated by the air compressor 1 during operation, effectively improving energy utilization.

[0030] In addition, pump bodies 8 are installed on the heat medium inlet pipe 4, heat medium outlet pipe 5, water inlet pipe 6, water outlet pipe 7, and water supply pipe 9. The pump bodies 8 are used to provide power. In actual use, the pump body 8 is selected as either an air pump or a water pump based on the type of medium in the pipeline.

[0031] Working Principle: Hot oil is heated in air compressor 1 to form high-temperature oil vapor, which enters heat exchanger 2 through heat medium inlet pipe 4. Room temperature water in hot water storage tank 3 flows into heat exchanger 2 through outlet pipe 7. Heat exchanger 2 transfers the heat from the high-temperature oil vapor to the room temperature water, thus heating the water. Once the water temperature reaches the required level, it enters hot water storage tank 3 through inlet pipe 6 for storage. When the cleaning machine needs water replacement, hot water in hot water storage tank 3 flows into the cleaning machine through water supply pipe 9. The high-temperature oil vapor is cooled after passing through heat exchanger 2 and then output from heat medium outlet pipe 5 back to air compressor 1 for further heating.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
