Description

Technical Field

[0001] This utility model patent relates to the field of waste heat recovery technology, and in particular to a heat energy recycling and reuse exchange device for heating and ventilation ducts. Background Technology

[0002] Currently, waste heat recovery technology is used in peripheral power equipment such as air compressors in the lithium battery industry to recover heat and reduce energy consumption. However, during the lithium battery production process, various mechanical equipment such as fans and motors, as well as process procedures, also generate a large amount of waste heat. If this heat is not effectively recovered and utilized, it will not only waste energy but also increase the temperature inside the factory, affecting the comfort of the working environment and the operating efficiency of production equipment. At present, the HVAC systems in lithium battery production plants often rely on external energy inputs such as electric heating and boiler steam to handle air heating and ambient temperature regulation, which further increases energy consumption and operating costs.

[0003] Existing factory preheating and recovery systems typically recover large amounts of hot air directly. For example, application number CN201721867317.0 describes an industrial plant waste heat recovery and utilization system that collects waste heat, connects the waste heat collection point to the waste heat usage point, and transports the hot air to the lowest usage point in the factory after dust suppression treatment, achieving the result of recycling and reusing the waste heat within the factory for heating. This utility model is typically applied to high-temperature factories such as coal, oil, and steel plants, but is not suitable for lithium battery production plants. Utility Model Content

[0014] Furthermore, the heat sink has multiple fins on its outer side.

[0015] The technical effect achieved by the above configuration is that the heat transfer fluid is heated fully and evenly through multiple fins.

[0016] Furthermore, the clamp is provided with a clamping groove and an adjusting bolt for adjusting the gap between the inner sidewalls of the clamping groove, the clamping groove being used to clamp the flexible heat-conducting sheet.

[0017] The technical effect achieved by the above settings is that it facilitates the replacement of flexible heat-conducting sheets of different specifications, or the replacement of damaged flexible heat-conducting sheets.

[0018] Furthermore, the end of the connecting duct is connected to the heating duct via a connecting frame.

[0019] The technical effect achieved by the above settings is to make the connection between the connecting air duct and the heating air duct more secure.

[0020] Furthermore, the heat exchange holes are evenly distributed on the heat exchange block.

[0021] The technical effect achieved by the above settings is that the airflow is heated more evenly.

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical utility model of the present invention, and should not be construed as limiting the scope of protection of the present invention.

[0039] Example 1: This example provides a heat energy recycling and reuse exchange device for a heating and ventilation duct, including: a connecting duct 1, which is connected to a heating and ventilation duct; a heat exchange component is provided inside the connecting duct 1, which is connected to a heat absorption component through a heat conduction component. The heat absorption component is in contact with the heating device, fully absorbing the heat from the heating device, and transferring the heat to the heat exchange component through the heat conduction component. The heat exchange component heats the airflow entering the connecting duct 1, and the heated airflow enters the heating and ventilation duct for utilization. This not only achieves the cyclic cooling of the heating device, but also recycles the heat from the heating device.

[0040] Example 2: Based on the concept of Example 1, this example refines the structure of the heat exchange component, the heat conduction component, and the heat absorption component.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, the heat exchange component heat exchange block 3 has multiple heat exchange through holes 301, and multiple heat-conducting meshes 15 are arranged inside the heat exchange through holes 301. The connecting air duct 1 can be connected to the heating and ventilation duct through the connecting frame 2. When the airflow enters the interior of the connecting air duct 1, the airflow passes through the heat exchange through holes 301 in the heat exchange block 3. When it passes through the heat-conducting meshes 15, it quickly absorbs the heat from the heat-conducting meshes 15. After the airflow is heated, it enters the heating and ventilation duct to recover and utilize the heat.

[0042] like Figure 1 , Figure 4 and Figure 5As shown, the heat-conducting assembly includes a liquid storage box 6 and a pipe 5. The heat exchange block 3 is hollow, with a first liquid inlet 4 and a first liquid outlet connected to its bottom. The top of the liquid storage box 6 is connected to a second liquid inlet 14 and a second liquid outlet. The second liquid outlet is connected to the first liquid inlet 4 via the pipe 5, and the second liquid inlet 14 is connected to the first liquid outlet via the pipe 5. The second liquid outlet is equipped with a pump 8 for drawing the heat-conducting liquid 16 from the liquid storage box 6 into the heat exchange assembly 3. Under the action of the pump 8, the heat-conducting liquid 16 can circulate among the heat exchange block 3, the pipe 5, and the liquid storage box 6 to transfer heat to the heat exchange block 3. The heat-conducting liquid 16 is preferably an oil with good thermal conductivity. The pipe 5 is preferably a corrugated pipe with an adjustable shape to adapt to different spatial arrangement requirements.

[0043] like Figures 1-3 As shown, the heat absorption assembly includes a clamp 9, a heat sink 11, and multiple flexible heat-conducting sheets 10. The clamp 9 is fixedly installed at the bottom of the liquid storage box 6, and the heat sink 11 is fixedly installed at the top of the clamp 9. The heat sink 11 is located inside the liquid storage box 6 and has multiple fins 12. The bottom of the clamp 9 has a clamping groove 901. The top of the flexible heat-conducting sheet 10 extends into the clamping groove 901 and is in contact with the inner sidewall of the clamping groove 901. The flexible heat-conducting sheet 10 is supported by a flexible metal material. In use, the flexible heat-conducting sheet 10 is attached to the heating position of the heating device with high-temperature resistant thermally conductive adhesive. The flexibility of the flexible heat-conducting sheet 10 allows it to fit well into the device, thereby improving the heat transfer efficiency. The heat absorbed by the flexible heat-conducting sheet 10 is transferred to the liquid storage box 6, and then transferred to the heat-conducting liquid 16 inside the liquid storage box 6 through the fins 12 on the heat sink 11, causing the heat-conducting liquid 16 to heat up. The heat-conducting liquid 16 is then transferred to the heat exchange block 3.

[0044] like Figure 1 and Figure 2 As shown, mounting plates 7 are fixedly installed at both ends of the liquid storage box 6. The mounting plates 7 have through holes to fix the liquid storage box 6 to the equipment. Adjusting bolts 13 are installed at both ends of the clamp 9. The width of the clamping groove 901 can be adjusted by rotating the adjusting bolts 13. After the width is widened, the flexible heat-conducting sheet 10 can be removed to facilitate the replacement of flexible heat-conducting sheets 10 of different lengths to adapt to different equipment, or to replace the damaged flexible heat-conducting sheet 10.
