Description

Technical Field

[0001] This utility model relates to the field of oil-water heat exchange technology, specifically an integrated high-efficiency oil-water heat exchange device for air compressors. Background Technology

[0002] During the operation of an air compressor, the oil-water heat exchanger plays a crucial role. It is responsible for exchanging and dissipating the heat generated by the air compressor to ensure stable operation in a suitable temperature environment. However, most existing integrated air compressor oil-water heat exchangers suffer from low heat exchange efficiency. Traditional heat exchangers have relatively simple structures, and the flow paths and contact methods of oil and water within the heat exchanger are not ideal, resulting in insufficient and rapid heat transfer. For example, some heat exchangers use only a single heat exchange tube structure, limiting the heat exchange area between oil and water. Furthermore, the flow state of the fluid within the heat exchanger is not optimized, making the heat exchange process inefficient and unable to quickly and effectively remove the heat generated by the air compressor, thus affecting the overall performance and service life of the air compressor.

[0003] Besides the issue of heat exchange efficiency, existing oil-water heat exchange devices for air compressors also have shortcomings in auxiliary heat exchange and operation monitoring. Regarding auxiliary heat exchange, there is a lack of effective agitation devices to enhance convective heat transfer between oil and water. When oil and water are relatively still or flowing slowly within the heat exchanger, the thermal boundary layer is thick, hindering heat transfer. Most existing devices lack corresponding agitation structures to address this problem. In terms of operation monitoring, many heat exchange devices are not equipped with comprehensive temperature and liquid level monitoring equipment, making it impossible to accurately monitor temperature and liquid level changes within the heat exchanger in real time. This prevents timely adjustments to operating parameters, potentially leading to excessively high temperatures affecting heat exchange efficiency or abnormal liquid levels impacting normal operation and even causing safety accidents. Therefore, we propose an integrated high-efficiency oil-water heat exchange device for air compressors to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated high-efficiency oil-water heat exchange device for air compressors, thereby solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: an integrated high-efficiency oil-water heat exchange device for an air compressor, comprising a heat exchanger shell, wherein serpentine heat exchange tubes are fixedly installed in the upper and lower parts of the interior of the heat exchanger shell, and the left ends of two serpentine heat exchange tubes are connected by an installed connecting pipe. A mounting base is fixedly installed in the middle of the left side wall of the heat exchanger shell, and a drive motor is installed on the top surface of the mounting base by bolts. A rotating shaft is installed at the output end of the drive motor, penetrating and extending into the interior of the heat exchanger shell. Multiple sleeves are evenly installed on the outer ring of the rotating shaft inside the heat exchanger shell, and multiple agitator blades are evenly fixedly installed on the outer ring of the sleeves.

[0006] As a preferred embodiment of this utility model, an oil inlet pipe is fixedly installed on the upper right side of the heat exchanger shell, and the oil inlet pipe is connected to the right end of a serpentine heat exchange tube located at the top.

[0007] As a preferred embodiment of this utility model, an oil outlet pipe is fixedly installed on the lower right side of the heat exchanger shell, and the oil outlet pipe is connected to the right end of a serpentine heat exchanger pipe located at the bottom.

[0008] As a preferred embodiment of this utility model, an inlet pipe is installed on the upper right side of the heat exchanger shell, extending through and into the interior of the heat exchanger shell, and an outlet pipe is installed on the lower left side of the heat exchanger shell, extending through and into the interior of the heat exchanger shell.

[0009] As a preferred embodiment of this utility model, there are two connecting pipes, and the two connecting pipes are respectively connected to the two sides of the left end of the two serpentine heat exchange tubes.

[0010] As a preferred embodiment of this utility model, the right end of the rotating shaft is rotatably connected to the right inner wall of the heat exchanger shell, a thermometer is installed on one side of the heat exchanger shell, and a liquid level sensor extending into the interior of the heat exchanger shell is installed on the top side of the heat exchanger shell.

[0011] In a preferred embodiment of this invention, the drive motor, liquid level sensor, and thermometer are uniformly connected to a controller, which can be a PLC controller.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This integrated high-efficiency oil-water heat exchange device for air compressors features serpentine heat exchange tubes installed both inside the upper and lower parts of the heat exchanger shell. Two connecting pipes connect the left ends of the two serpentine heat exchange tubes, forming a unique oil circulation structure. The oil inlet pipe is connected to the right end of the upper serpentine heat exchange tube, and the oil outlet pipe is connected to the right end of the lower serpentine heat exchange tube. Simultaneously, the water inlet pipe and water outlet pipe are respectively located on the upper right side and lower left side of the heat exchanger shell, ensuring full contact between water and oil within the shell.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 An integrated high-efficiency oil-water heat exchange device for an air compressor includes a heat exchanger shell 1. First, the heat exchanger shell 1 is constructed by selecting materials with appropriate strength and corrosion resistance to ensure that it can stably accommodate the internal structure. Inside the heat exchanger shell 1, serpentine heat exchange tubes 10 are precisely fixed and installed at the upper and lower parts. The bending radius and spacing of the serpentine heat exchange tubes 10 are reasonably designed according to the heat exchange requirements and shell space to ensure that there is sufficient heat exchange area and appropriate flow when oil and water flow in it. Two connecting pipes 14 are tightly connected to the two sides of the left end of the two serpentine heat exchange tubes 10 respectively, and the connection is well sealed to prevent oil or water leakage.

[0018] An oil inlet pipe 3 is installed on the upper right side of the heat exchanger shell 1 and reliably connected to the right end of the upper serpentine heat exchange tube 10, so that the oil can smoothly enter the upper serpentine heat exchange tube 10. An oil outlet pipe 4 is installed on the lower right side of the heat exchanger shell 1 and connected to the right end of the lower serpentine heat exchange tube 10 so that the oil after heat exchange can flow out. A water inlet pipe 2 is installed on the upper right side of the heat exchanger shell 1, penetrating and extending into the interior, and a water outlet pipe 6 is installed on the lower left side, penetrating and extending into the interior, so as to realize the circulation of water.

[0019] Next, a mounting base 7 is fixedly installed in the middle of the left side wall of the heat exchanger shell 1. The drive motor 8 is securely installed on the top surface of the mounting base 7 with bolts. The rotating shaft 12 is installed at the output end of the drive motor 8, and the right end of the rotating shaft 12 is rotatably connected to the inner wall of the right side of the heat exchanger shell 1 to ensure that the rotating shaft 12 can rotate smoothly. Multiple sleeves 11 are evenly installed on the outer ring of the rotating shaft 12 inside the heat exchanger shell 1. Multiple agitator blades 13 are evenly fixed on the outer ring of each sleeve 11. The shape and angle of the agitator blades 13 should be designed to effectively agitate the fluid in the heat exchanger and enhance convective heat transfer.

[0020] A thermometer 5 is installed on one side of the heat exchanger housing 1, and a liquid level sensor 9 extending into the heat exchanger housing 1 is installed on the top side. The drive motor 8, the liquid level sensor 9, and the thermometer 5 are evenly connected to the PLC controller. During operation, oil enters the upper serpentine heat exchange tube 10 from the oil inlet pipe 3, and water enters the serpentine heat exchange tube 10 inside the heat exchanger housing 1 from the water inlet pipe 2. The drive motor 8 drives the rotating shaft 12 to rotate, and the agitator blades 13 agitate the water to enhance the heat exchange effect. After heat exchange, the oil flows out from the oil outlet pipe 4, and the water flows out from the water outlet pipe 6. The liquid level sensor 9 monitors the liquid level in real time, and the thermometer 5 monitors the temperature and transmits the data to the PLC controller. When the liquid level or temperature is abnormal, the PLC controller controls the drive motor 8 and other components to make corresponding adjustments.

[0021] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 First, the heat exchanger housing 1 can be fixedly installed in a suitable position. Then, the compressed air oil on the air compressor can be connected to one end of the oil inlet pipe 3 through the oil pump, and the oil outlet pipe 4 can be connected to the air compressor's oil storage port, so that the compressed air oil circuit of the air compressor forms a circulation, which facilitates the heat exchange of the compressed air oil in the air compressor.

[0022] For the water circuit, a water pipe is connected to the inlet pipe 2, and the heat exchange water can be pumped into the heat exchanger shell 1 for heat exchange. After the heat exchange of the water is completed, the water can be transported to the insulated water storage tank through the outlet pipe 6 for storage, so that it can be reused.

[0023] When installing the drive motor 8, a shock-absorbing pad is added between the mounting base 7 and the drive motor 8 to reduce the impact of the vibration of the drive motor 8 during operation on the heat exchanger shell 1. The sleeve 11 and the agitator blade 13 on the rotating shaft 12 are made of wear-resistant and corrosion-resistant materials, which can extend their service life.

[0024] The thermometer 5 and the liquid level sensor 9 are selected as high-precision models to improve the accuracy of temperature and liquid level monitoring. After connecting them to the PLC controller, more refined control parameters can be set. For example, when the temperature exceeds a certain range of the set value, the PLC controller not only controls the drive motor 8 to accelerate rotation and enhance agitation, but also controls the water inlet flow rate to reduce the temperature more quickly.

[0025] At the same time, the system's flexibility is improved. In actual operation, when the liquid level sensor 9 detects that the liquid level is too low, the PLC controller not only issues an alarm, but also automatically stops the operation of the drive motor 8 and reminds people to take corresponding measures to prevent equipment damage due to lack of water or oil.

[0026] Implementation effect: This device has serpentine heat exchange tubes 10 installed in the upper and lower parts of the heat exchanger shell 1, and the left ends of the two serpentine heat exchange tubes 10 are connected by two connecting pipes 14 to form a unique oil circulation structure. The oil inlet pipe 3 is connected to the right end of the upper serpentine heat exchange tube 10, and the oil outlet pipe 4 is connected to the right end of the lower serpentine heat exchange tube 10. At the same time, the water inlet pipe 2 and the water outlet pipe 6 are respectively located in the upper right side and lower left side of the heat exchanger shell 1, so that water and oil can fully contact each other in the shell. This layout greatly increases the heat exchange area of ​​oil and water, prolongs the heat exchange time, and thus significantly improves the heat exchange efficiency, allowing the heat generated by the air compressor to be carried away by water more quickly and effectively.

[0027] The drive motor 8 can be started by the PLC controller. The output of the drive motor 8 can drive the rotating shaft 12 to rotate, which in turn can drive the stirring fan blade 13 to rotate through the sleeve 11. This allows the stirring fan blade 13 to stir the hot water inside the heat exchanger shell 1, enhance the convective heat exchange effect, and further improve the heat exchange efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
