Description

Technical Field

[0001] This utility model relates to the field of cooling pipe technology, and in particular to a cooling pipe casting for an air compressor. Background Technology

[0002] Cooling pipe castings play a crucial role in the operation of air compressors. Air compressors generate a significant amount of heat during gas compression; if this heat cannot be dissipated effectively and promptly, it will severely impact the compressor's performance, reliability, and lifespan. As a key component of the heat dissipation system, cooling pipe castings bear the important responsibility of transferring the heat generated during compression.

[0003] Most existing air compressor cooling pipe castings adopt a single-pipe structure. This structure has revealed many drawbacks in practical applications, the most prominent of which is insufficient strength and impact resistance. Under prolonged high-temperature environments, the castings are prone to deformation and damage due to overheating, which seriously affects the service life of the cooling pipe castings and the stable operation of the air compressor. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling pipe casting for air compressors. The outer shell protects the cooling pipe, improving its impact resistance and increasing its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cooling pipe casting for an air compressor includes a pipe body, with connecting flanges fixedly connected to both ends of the pipe body. A spiral guide plate is fixedly connected to the outside of the pipe body, with fixing rings fixedly connected to both ends of the spiral guide plate. The opposite ends of the fixing rings are fixedly connected to the opposite side of the connecting flanges. Locating bolts are fixedly connected to both the upper and lower sides of the fixing rings. Outer shells are provided on both the upper and lower sides of the pipe body. Locating holes are provided at both ends of the outer shells, with the locating bolts passing through the locating holes. A reinforcing strip is fixedly connected to the outside of the outer shells. A ventilation assembly is provided at the upper end of the outer shell of the pipe body.

[0007] Furthermore, both the front and rear ends of the outer shell are fixedly connected with sealing edges, and through holes for fixing are provided on the outer side of each sealing edge.

[0008] Furthermore, the ventilation assembly includes an air inlet at the right end of the housing and an air outlet fixedly connected to the left end of the housing, with a fan installed inside the air outlet.

[0009] Furthermore, the external thread of the air outlet is connected to a connecting ring, and a protective plate is fixedly connected to the upper side of the connecting ring.

[0010] Furthermore, a threaded hole is provided at the right end of the outer casing, located to the left of the air inlet.

[0011] Furthermore, a filter screen is provided on the outer right end of the outer casing.

[0012] Furthermore, a fastener is provided at the left end of the filter screen, and the end of the fastener is threaded into the inside of a threaded hole.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the outer shell is installed on the outside of the tube body by setting the sealing edge to protect it, and the protective effect of the outer shell is increased by setting the reinforcing strip, thereby improving the impact resistance of the cooling tube and extending its service life.

[0021] 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.

[0022] Reference Figures 1-3 The present invention provides an embodiment of a cooling pipe casting for an air compressor, comprising a pipe body 1, connecting flanges 2 fixedly connected to both ends of the pipe body 1, a spiral guide plate 3 fixedly connected to the outside of the pipe body 1, fixing rings 4 fixedly connected to both ends of the spiral guide plate 3, one end of the fixing ring 4 fixedly connected to the opposite side of the connecting flange 2, positioning bolts 5 fixedly connected to both the upper and lower sides of the fixing ring 4, an outer shell 6 provided on both the upper and lower sides of the pipe body 1, positioning holes 7 provided at both ends of the outer shell 6, positioning bolts 5 passing through the positioning holes 7, a reinforcing strip 8 fixedly connected to the outside of the outer shell 6, and sealing edges 9 fixedly connected to both the front and rear ends of the outer shell 6, with through holes 10 for fixing provided on the outside of the sealing edges 9.

[0023] The outer shell 6 is installed on the outside of the tube 1. During installation, the positioning holes 7 at both ends of the outer shell 6 are aligned with the positioning bolts 5. The positioning bolts 5 are inserted into the positioning holes 7 for positioning and initial fixation. Then, the outer shell 6 is fixed by the bolts and nuts engaging with the through holes 10. The outer shell 6 is installed on the outside of the tube 1 by the sealing edge 9 for protection. The reinforcing strip 8 is used to increase the protective effect of the outer shell 6, improve the impact resistance of the cooling tube, and extend its service life.

[0024] Reference Figures 1-3 An air inlet 11 is provided at the right end of the outer casing 6. The ventilation assembly also includes an air outlet 15 fixedly connected to the left end of the outer casing 6. A fan 16 is installed inside the air outlet 15. A connecting ring 17 is threadedly connected to the outside of the air outlet 15. A protective plate 18 is fixedly connected to the upper side of the connecting ring 17. A threaded hole 12 is provided at the right end of the outer casing 6 to the left of the air inlet 11. A filter screen 13 is provided on the outside of the right end of the outer casing 6. A fastener 14 is threaded through the left end of the filter screen 13. The end of the fastener 14 is threadedly connected to the inside of the threaded hole 12.

[0025] When the air compressor is running, the fan 16 inside the air outlet 15 is activated, driving external air to be drawn in from the air inlet 11 and flowing through the annular air duct formed by the spiral guide plate 3 and the pipe body 1. The spiral guide plate 3 extends the airflow path and enhances turbulence, significantly improving the heat exchange efficiency of the pipe body 1 surface. Finally, the hot air is accelerated and discharged by the fan 16, forming directional forced convection, which solves the problem of insufficient traditional natural heat dissipation. The detachable filter screen 13 is fixed to the threaded hole 12 by the fastener 14, which is convenient for regular cleaning or replacement, and the maintenance is highly convenient.

[0026] Working principle: The outer shell 6 is installed on the outside of the tube 1. During installation, the positioning holes 7 at both ends of the outer shell 6 are aligned with the positioning bolts 5. The positioning bolts 5 are inserted into the positioning holes 7 for positioning and initial fixation. Then, the outer shell 6 is fixed by bolts and nuts engaging with the through holes 10. During the use of the cooling tube, the fan 16 is activated to drive the airflow inside the outer shell 6, forming a strong airflow. This airflow, combined with the air inlet 11, forms an air intake and exhaust cycle, thereby improving the heat dissipation effect of the tube 1. The filter screen 13 filters the incoming air, preventing larger impurities from entering. The outer shell 6 protects the cooling tube, and the reinforcing strips 8 enhance its impact resistance and extend its service life.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
