Description

Technical Field

[0001] This utility model belongs to the technical field of gas compressor cooling equipment, specifically relating to a cooling device for a sleeve-fin type gas compressor. Background Technology

[0002] Gas compressors, especially air compressors, mostly use coil-type air-cooled gas coolers for interstage or final-stage cooling, while some with higher cooling requirements use shell-and-tube liquid-cooled structures. Existing coil-type air-cooled coolers typically use a fan to directly blow heat onto the coils, resulting in low cooling capacity, large coil size, and complex structure. Shell-and-tube liquid-cooled coolers, on the other hand, usually consist of a bundle of tubes and a shell, leading to numerous pipes, complex system structure, complex manufacturing processes, large size and weight, difficult maintenance, and limited cooling capacity. Both types of coolers suffer from large size, low cooling efficiency, and low reliability, affecting the overall system lifespan and operating efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cooling device for a sleeve-finned gas compressor, aiming to ensure cooling effect while achieving rapid installation. This invention first achieves rapid positioning and assembly of the cooling device and the gas compressor through mounting bosses. Then, the gas pipeline to be cooled is quickly installed to the gas passage through the inlet flange and exhaust flange. The cooling medium inside the spiral channel achieves rapid cooling of the gas, and the heat dissipation fins increase the heat dissipation area, thereby improving the cooling efficiency of the cooling device.

[0004] This utility model is mainly achieved through the following technical solutions:

[0005] A cooling device for a shell-and-tube finned gas compressor includes an outer tube and an inner tube. The outer tube has a fitting mounting cavity corresponding to the inner tube. Heat dissipation fins spirally arranged circumferentially along the outer wall of the inner tube are provided between the mounting cavity and the inner tube to form a spiral channel between the mounting cavity and the inner tube. The inner tube has a gas cooling channel, and the spiral channel has a cooling medium channel.

[0006] The outer sleeve has a mounting boss on one side. The upper left and right ends of the outer sleeve are respectively provided with an exhaust flange and an inlet flange that communicate with the cooled gas channel. The middle of the inlet flange and the exhaust flange are respectively provided with an inlet port and an exhaust port. The cooled gas pipelines at the inlet and outlet ends of the gas compressor are detachably connected to the exhaust flange and the inlet flange, respectively. The upper left end of the outer sleeve is provided with a cooling medium inlet flange that communicates with the spiral channel. The middle of the cooling medium inlet flange is provided with a liquid inlet. The upper right end of the outer sleeve is correspondingly provided with a drain port that communicates with the spiral channel.

[0007] To better realize this utility model, threaded holes are provided on both sides of the air inlet flange and the air outlet flange, and end face sealing grooves are provided on the outer sides of the air inlet and the air outlet respectively; connecting through holes are provided at both ends of the mounting boss for detachable connection with the compressor.

[0008] To better realize this utility model, further, one end of the cooled gas pipeline is provided with a connecting flange corresponding to the inlet flange or the exhaust flange, the middle of the connecting flange is provided with a connecting hole, and a first magnetic ring is provided on the outer periphery of the connecting hole, and a second magnetic ring is provided inside the end face sealing groove, and the first magnetic ring and the second magnetic ring are attracted by magnetism.

[0009] To better realize this utility model, the gas flow direction in the cooled gas channel is opposite to the cooling medium flow direction in the cooling medium channel, so as to form countercurrent cooling.

[0010] To better realize this utility model, the outer cylindrical surface of the heat dissipation fin is connected to the inner wall surface of the outer sleeve, and the inner cylindrical surface is connected to the outer wall surface of the inner sleeve.

[0011] To better realize this utility model, the outer sleeve, heat dissipation fins and inner sleeve are further integrated into a single sleeve; the inner sleeve is arranged axially inside the outer sleeve, and the outer sleeve and the inner sleeve are coaxially arranged.

[0012] To better realize this utility model, the outer sleeve and the inner sleeve are further arranged in an elliptical spiral along the horizontal direction.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model ensures the cooling effect through the structure of the outer sleeve, heat dissipation fins, and inner sleeve. Secondly, this utility model first achieves rapid positioning and assembly of the cooling device and the gas compressor through the mounting boss, and then quickly installs the cooled gas pipeline and the cooled gas passage through the inlet flange and exhaust flange. Furthermore, this utility model achieves rapid alignment of the matching second magnetic ring on the matching inlet flange or exhaust flange through the first magnetic ring on the connecting flange on the cooled gas pipeline, which accelerates the installation and improves the reliability of the installation, thus having good practicality.

[0015] (2) This utility model integrates a cooled gas channel and a cooling medium channel within the outer sleeve, forming an integrated spiral layout. The overall structure is compact, enabling miniaturization and offering advantages in size and weight. Specifically, the outer sleeve, heat dissipation fins, and inner sleeve are integrated. The outer sleeve and its internal inner sleeve and heat dissipation fins are arranged in an elliptical spiral pattern. The heat dissipation fins are long and have a large heat dissipation area, resulting in high cooling efficiency. The cooling device can be integrally 3D printed, enabling the integration and layout design of the cooled gas channel and cooling medium channel. This not only facilitates processing and shortens the manufacturing cycle but also ensures high reliability. Furthermore, it reduces many internal pipe connections, resulting in high reliability and convenient installation and maintenance. Attached Figure Description

The inner sleeve 3 has a cooling gas channel inside, and the spiral channel between the mounting cavity, the inner sleeve 3 and the heat dissipation fins 2 is a cooling medium channel.

[0028] Preferably, threaded holes are provided on both sides of the inlet flange 4 and the exhaust flange 5, and end-face sealing grooves are provided on the outer sides of the inlet port 41 and the exhaust port 51, respectively; connecting through holes are provided at both ends of the mounting boss 7 for detachable connection with the compressor. Preferably, a connecting flange is provided at one end of the cooled gas pipeline corresponding to the inlet flange 4 or the exhaust flange 5, a connecting hole is provided in the middle of the connecting flange, and a first magnetic ring is provided on the outer periphery of the connecting hole.

This utility model achieves rapid alignment of the first magnetic ring on the connecting flange of the cooled gas pipeline with the matching second magnetic ring on the inlet flange 4 or the exhaust flange 5, which accelerates installation and improves installation reliability, thus having good practicality.

[0029] Preferably, the outer sleeve 1, heat dissipation fins 2 and inner sleeve 3 are an integral sleeve. In this case, the outer sleeve 1 and the inner sleeve 3 are coaxially arranged, which can be regarded as the outer sleeve 1 covering the outer side of the inner sleeve 3, and a spiral channel is provided between the outer sleeve 1 and the inner sleeve 3 to allow the cooling medium to pass through.

[0030] Preferably, the gas flow direction in the cooled gas channel is opposite to the cooling medium flow direction in the cooling medium channel, thus forming countercurrent cooling. Specifically, the upper left and right ends of the outer sleeve 1 are respectively provided with a liquid inlet 61 and a liquid outlet 62.

[0031] During use, this invention can be quickly installed on a gas compressor via the mounting boss 7 on one side. Correspondingly, the cooled gas pipeline at the outlet end of the gas compressor is connected to the inlet flange 4, and the cooled gas pipeline at the inlet end is connected to the exhaust flange 5. The cooling medium pipeline at the liquid outlet end is connected to the liquid inlet 61, and the cooling medium pipeline at the liquid inlet end is connected to the liquid outlet 62. This invention features a compact structure, stable and reliable connections, and excellent internal cooling effect.

[0032] Example 2:

[0033] A cooling device for a shell-and-tube finned gas compressor, such as Figures 1-3As shown, the device includes an outer sleeve 1, which adopts a multi-purpose design concept and is arranged in an elliptical spiral along the horizontal direction. Inside the outer sleeve 1, a coaxial spiral structure inner sleeve 3 is arranged. Between the outer sleeve 1 and the inner sleeve 3, heat dissipation fins 2 are arranged spirally along the outer wall of the inner sleeve 3. The outer cylindrical surface of the heat dissipation fins 2 connects to the inner wall of the outer sleeve 1, and its inner cylindrical surface connects to the outer wall of the inner sleeve 3. Both the outer surface of the heat dissipation fins 2 and the outer wall of the inner sleeve 3 are heat dissipation surfaces in contact with the cooling medium. The arrangement of the heat dissipation fins 2 increases the heat dissipation area and improves the cooling efficiency of the cooling device. Preferably, the outer sleeve 1, heat dissipation fins 2, and inner sleeve 3 are an integral structure. Specifically, the outer sleeve 1, heat dissipation fins 2, and inner sleeve 3 constitute an integrated molded sleeve structure. The outer sleeve 1 is arranged in an elliptical spiral along the horizontal direction and is closely connected. Compared with other coolers, the cooling device of this utility model has a more compact structure, smaller size, lighter weight, and longer heat dissipation pipe, which greatly improves the cooling efficiency.

[0034] like Figure 4 and Figure 5 As shown, the inner sleeve 3 has a cooled gas channel inside, and the spiral channel between the outer sleeve 1, the heat dissipation fins 2, and the inner sleeve 3 is a cooling medium channel. The cooled gas channel is used for the flow of cooled gas, which enters from the inlet 41 and exits from the outlet 51. The cooling medium channel is used for the flow of cooling medium, which enters from the liquid inlet 61 and exits from the liquid outlet 62. Specifically, the outer sleeve 1 is externally integrated with an inlet flange 4, an outlet flange 5, a cooling medium inlet flange 6, and a mounting boss 7. Specifically, one end of the cooled gas channel is connected to the inlet 41 on the inlet flange 4, and the other end is connected to the outlet 51 on the outlet flange 5.

[0037] The mounting boss 7 has two through holes, through which the cooling device can be fixed to the compressor with bolts, making installation convenient and reliable.

[0038] Preferably, when the cooling device of this utility model is working, the gas to be cooled enters from the air inlet 41 at the right end of the outer tube 1 and exits from the exhaust port 51 at the left end, while the cooling medium enters from the liquid inlet 61 at the left end of the outer tube 1 and exits from the liquid outlet 62 at the right end. The flow directions of the gas to be cooled and the cooling medium are opposite, which is a counter-current cooling scheme. The flow rate of the cooling medium relative to the gas to be cooled is high, which greatly improves the cooling efficiency.

[0039] The cooling medium can be compressed air, coolant, or water, which is readily available and easy to obtain. The cooling flow rate can be adjusted according to the temperature of the gas being cooled.

[0040] The entire cooling device can be made of aluminum alloy or copper alloy with hard anodizing or passivation surface treatment. Both materials have high heat transfer coefficients, resulting in high cooling efficiency, light weight, high strength, and excellent corrosion resistance, thus extending service life. The entire cooling device can be manufactured using 3D printing additive manufacturing, enabling the integration and layout design of the cooled gas channels and cooling medium channels. This reduces many internal piping connections, making processing and molding easier, shortening the manufacturing cycle, and ensuring high reliability and convenient installation and maintenance.
