Technical Field

[0001] This utility model relates to the field of air compressor technology, and more specifically, to an intercooler and an air compressor. Background Technology

[0002] Air compressors are important equipment in industrial production and are mainly used to compress air. During the operation of an air compressor, the compressed air will generate a lot of heat, which will cause the gas temperature to rise. In order to improve compression efficiency and reduce energy consumption, an intercooler is usually installed in the air compressor system to cool the compressed air and lower its temperature.

[0003] Currently, the cooling core in intercoolers is fixed and cannot be disassembled. When impurities, dust, or oil accumulate on the surface of the cooling core in the compressed air, it leads to a decrease in cooling efficiency. Because the cooling core is fixed, the entire intercooler needs to be maintained or replaced, which not only increases maintenance costs but also reduces cooling efficiency and ease of maintenance, affecting the normal operating efficiency of the equipment.

[0025] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0026] like Figures 1 to 3 As shown, an embodiment of this utility model provides an intercooler, including a cooling shell 10 and a cooling core 20. The cooling shell 10 includes a cooling cylinder 11, an inlet pipe 12, and an outlet pipe 13. The cooling cylinder 11 has a cooling chamber 111. The inlet pipe 12 and the outlet pipe 13 are installed at intervals in the cooling cylinder 11 and are both connected to the cooling chamber 111 to input and output gas into and out of the cooling chamber 111. The cooling core 20 includes a cooling body 21, a liquid inlet pipe 22, and a liquid outlet pipe 23. The liquid inlet pipe 22 and the liquid outlet pipe 23 are both connected to the cooling body 21 and are used to input and output cooling fluid into and out of the cooling body 21. The cooling core 20 and the cooling shell 10 are detachably connected. When the cooling core 20 and the cooling shell 10 are connected, the cooling body 21 extends into the cooling chamber 111 and is used to cool the gas in the cooling chamber 111.

[0027] In this design, the inlet pipe 12 and outlet pipe 13 are installed alternately on the cooling cylinder 11, which extends the flow path of compressed air in the cooling chamber and enhances the cooling effect. With the cooling core 20 and the cooling shell 10 connected, the cooling body 21 extends into the cooling chamber 111. The cooling core 20 and the cooling shell 10 are detachably connected. When the cooling efficiency of the intercooler decreases due to the accumulation of impurities or oil, the cooling core 20 can be removed from the cooling shell 10 for cleaning or replacement. This makes the operation more convenient, avoids replacing the entire intercooler, greatly reduces maintenance costs, and ensures timely cleaning and replacement of the cooling filter element. This not only guarantees the cooling efficiency of the intercooler but also extends the service life of the equipment and enhances the reliability of equipment operation.

[0028] like Figure 1 As shown, the intercooler also includes a first temperature transmitter 31 and a second temperature transmitter 32. The first temperature transmitter 31 is installed on the inlet pipe 12, and the second temperature transmitter 32 is installed on the outlet pipe 13. By setting the first temperature transmitter 31 and the second temperature transmitter 32, the temperature of the compressed air at the inlet pipe 12 and the outlet pipe 13 can be monitored in real time, enabling timely detection of abnormal cooling efficiency and ensuring the efficient operation of the intercooler.

[0029] In this embodiment, the intercooler also includes a first pressure transmitter 33 and a second pressure transmitter 34. The first pressure transmitter 33 is installed in the inlet pipe 12, and the second pressure transmitter 34 is installed in the outlet pipe 13. By setting the first pressure transmitter 33 and the second pressure transmitter 34, the pressure of compressed air at the inlet pipe 12 and the outlet pipe 13 can be monitored in real time, enabling timely detection of equipment malfunctions and improving the stability and safety of equipment operation.

[0030] In this embodiment, the intercooler also includes a controller and an alarm. The first temperature transmitter 31, the second temperature transmitter 32, the first pressure transmitter 33, the second pressure transmitter 34, and the alarm are all electrically connected to the controller. The temperature and pressure transmitters, both electrically connected to the controller, can transmit the temperature and pressure parameters of the compressed air at the inlet pipe 12 and outlet pipe 13 to the controller in real time. The data is monitored and analyzed to determine if the cooling efficiency of the equipment is normal. If an abnormality occurs, the alarm is activated to remind the user to perform timely equipment maintenance.

[0031] like Figure 2 , Figure 3As shown, the inner wall of the cooling cylinder 11 has guide ribs 41, and the outer wall of the cooling body 21 has guide grooves 42, with the guide ribs 41 and guide grooves 42 slidingly engaged; or, the inner wall of the cooling cylinder 11 has guide grooves 42, and the outer wall of the cooling body 21 has guide ribs 41, with the guide ribs 41 and guide grooves 42 slidingly engaged. Multiple guide ribs 41 and guide grooves 42 are provided to facilitate the assembly between the cooling body 21 and the cooling cylinder 11, improve positioning accuracy, make the assembly process more stable and accurate, and avoid damage to components due to impacts.

[0032] In this embodiment, the cooling chamber 111 has a mounting port 1111, and the cooling shell 10 also includes a connecting flange 14, which is disposed around the mounting port 1111. The cooling core 20 also includes a sealing plate 24, which is disposed at one end of the cooling body 21. The sealing plate 24 and the connecting flange 14 are detachably connected and seal the mounting port 1111. The sealing plate 24 and the connecting flange 14, which are detachably connected, increase the connection strength between the cooling shell 10 and the cooling core 20 when they are fitted together, and facilitate the replacement of the cooling core 20, thus improving the convenience of operation.

[0033] In this embodiment, the cooling housing 10 also includes a sealing gasket disposed between the connecting flange 14 and the sealing plate 24. The sealing gasket between the connecting flange 14 and the sealing plate 24 significantly increases the sealing performance at the connection point, effectively reducing the risk of compressed air leaking from the connection.

[0034] like Figure 1 As shown, the cooling core 20 also includes a connecting cover 25 and a lifting ring 26. The connecting cover 25 is installed on the sealing plate 24. The inlet pipe 22 and the outlet pipe 23 are both installed on the side of the connecting cover 25, and the lifting ring 26 is installed on the top surface of the connecting cover 25. The inlet pipe 22 and the outlet pipe 23 are both installed on the side of the connecting cover 25 to facilitate the entry of cooling fluid into the cooling core 20. The lifting ring 26 is installed on the top surface of the connecting cover 25, providing a safe and reliable lifting point for equipment maintenance operations. Operators can pull the cooling core 20 out of the cooling shell 10 through the lifting ring 26, improving the safety and convenience of operation.

[0035] like Figure 3 As shown, the cooling body 21 includes a cooling pipe assembly 211 and a protective shell 212 surrounding the cooling pipe assembly 211. The inlet pipe 22 and outlet pipe 23 are both connected to the cooling pipe assembly 211. Multiple through holes 2121 are distributed on the protective shell 212. Compressed air flows through the through holes 2121 on the protective shell 212 through the cooling pipe assembly 211. The compressed air transfers heat to the cooling fluid in the cooling pipe assembly 211 through the pipe wall, achieving a cooling effect.

[0036] Optionally, the cooling housing 10 also includes a base, which is installed at the bottom of the cooling housing 10 and provides support for the entire device.

[0037] An embodiment of this utility model also provides an air compressor, which includes a compressor main unit and the aforementioned intercooler, with the outlet of the compressor main unit and the inlet pipe 12 of the intercooler connected. By integrating the aforementioned intercooler into the air compressor, efficient cooling and convenient maintenance of the air compressor are achieved, significantly improving the operating efficiency and reliability of the air compressor, reducing maintenance costs, and extending the service life of the equipment.

[0038] When the controller analyzes temperature and pressure parameters and detects a decrease in cooling efficiency, it activates an alarm to alert the user that equipment maintenance is required. Following the alert, the user shuts down the air compressor and disconnects the power supply to ensure the equipment stops operating. The user then disassembles the connecting flange 14 and the sealing plate 24, removing the sealing gasket to allow the cooling core 20 to be extracted. The user uses the lifting ring 26 to pull the cooling core 20 out of the cooling housing 10 and cleans it to remove surface deposits or other impurities. Cleaning methods include blowing with compressed air, cleaning with a soft brush, or rinsing with water. Care must be taken to avoid damaging the heat dissipation components during cleaning. After cleaning, the cooling core 20 is reinserted into the cooling housing 10, ensuring a tight seal. The compressed air line is reconnected, the air compressor is started, and the system returns to normal operation. If the problem persists, the controller will continue to activate the alarm, prompting the user to conduct further checks or contact technical support.

[0039] By adopting this intercooler and applying it to air compressors, the following significant benefits are achieved:

[0040] 1. Reduced maintenance costs: Traditional intercooler cores are fixed designs. When the cooling efficiency decreases due to scale buildup on the surface of the cooling core, users can only choose to replace the entire intercooler, which is costly. In contrast, the intercooler in this solution is designed as a removable cooling core 20. This allows users to remove the cooling core 20 for cleaning and maintenance when a decrease in cooling efficiency is detected, without having to replace the entire intercooler, thus significantly reducing maintenance costs.

[0041] 2. Improved maintenance convenience: The maintenance of traditional intercoolers is relatively complicated and time-consuming; however, this solution, through the design of the removable cooling core 20, makes the cleaning and maintenance of the cooling core 20 simpler, saving time and effort and significantly improving the convenience of maintenance.

[0042] 3. Improve equipment performance and reliability: Timely cleaning of the cooling core 20 can effectively restore cooling efficiency, avoid malfunctions such as overheating and performance degradation of the air compressor due to insufficient cooling of compressed air, improve the operating efficiency of the air compressor, and enhance the reliability of the equipment.

[0043] 4. Extend equipment lifespan: Cleaning the cooling core 20 becomes simpler, allowing for regular maintenance and repair. This effectively prevents wear and overheating caused by long-term dust or dirt accumulation, thus preventing a decline in the cooling performance of the equipment and extending its overall lifespan.

[0044] 5. Strong applicability: The intercooler of this solution adopts the design of a removable cooling core 20, which is not only suitable for magnetic levitation air compressors, but can also be applied to other types of air compressors or compression equipment, and has wide applicability and promotion value.
