Description

Technical Field

[0001] This utility model relates to the field of debugging device technology, and in particular to a split-type Stirling refrigerator debugging device. Background Technology

[0002] A commissioning device is a set of tools used to test, adjust, and optimize specific equipment or systems. In the refrigeration unit production process, each refrigeration unit needs to be tested by a commissioning device to ensure its performance meets quality standards. By testing parameters such as cooling capacity, efficiency, and stability, substandard products can be screened out, ensuring the reliability of the refrigeration units leaving the factory.

[0003] The separate Stirling chiller commissioning device can accurately measure the cooling capacity of a separate Stirling chiller under different operating conditions. By setting specific parameters such as ambient temperature and input power, it monitors the low temperature reached by the chiller after running for a period of time, and calculates the actual cooling capacity of the chiller by combining this with the heat load characteristics of the object being cooled.

[0004] In existing technologies, some commissioning devices are difficult to seal, and poor sealing can affect the test results of the refrigeration unit's performance. For example, leaked gas may lead to inaccurate pressure and temperature measurements, thereby affecting the assessment of refrigeration capacity, efficiency, and stability. This makes it difficult to guarantee the stability of the expander commissioning process and the accuracy of the commissioning results. Therefore, to address the above shortcomings, a split-type Stirling refrigeration unit commissioning device is proposed. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a split-type Stirling refrigerator debugging device, including an expander piston 1, which plays a key role in the device. It slides within an expander cylinder 2, changing the internal working volume of the refrigerator through its movement, thereby realizing the gas expansion process in the refrigeration cycle and providing power for refrigeration. The expander cylinder 2 is slidably connected to the outside of the expander piston 1, providing space and support for its sliding. Its inner wall tightly fits the expander piston 1, ensuring no leakage of the working gas during expansion. Simultaneously, the structural strength of the expander cylinder 2 ensures the stability of the refrigerator during operation. A flange 2 10 is fixedly connected to the left side of the expander cylinder 2, and a flange 1 9 is detachably connected to the left side of the flange 2 10. A bracket 8 is fixedly connected to the left side of the flange 1 9, and a threaded rod 4 is threadedly connected internally to the bracket 8. The threaded rod 4 is an important adjusting component in the debugging device. Through its threaded connection with the bracket 8, it can reciprocate linearly up and down along the axial direction. When the threaded rod 4 is rotated, its right side contacts the expander spring 3, which pushes the spring to move axially. A flange bracket 7 is fixedly connected to the inner left side of the bracket 8, providing the installation and support structure for the debugging device. It connects to the threaded rod 4 via a threaded connection, providing guidance and support for the movement of the threaded rod 4. Simultaneously, the flange bracket 7 is fixedly connected to the inner left side of the bracket 8, ensuring the overall stability of the debugging device. A corrugated hose 5 is fixedly connected to the right side of the flange bracket 7, connecting the flange 9 and the flange bracket 7, providing a flexible connection. During the operation of the refrigeration unit, the corrugated hose 5 can absorb dimensional changes caused by vibration or temperature variations, avoiding stress concentration and damage caused by rigid connections.

[0033] Reference Figure 1 , Figure 4 , Figure 5An expander spring 3 is fixedly connected to the left side of the expander piston 1. The expander spring 3, located to the left of the expander piston 1, provides a restoring force to the piston. During the operation of the refrigeration unit, the elasticity of the spring helps the piston reciprocate at a specific operating frequency, ensuring the smooth operation of the refrigeration cycle. An annular cavity 17 is formed inside the flange 19. A telescopic spring 18 is fixedly connected to the left inner wall of the annular cavity 17. A sliding ring 19 is fixedly connected to the right side of the telescopic spring 18. A sliding ring 20 is fixedly connected to the right side of the sliding ring 19. A sealing gasket 21 is fixedly connected to the right side of the sliding ring 20. The sealing gasket 21 is installed on the right side of the sliding ring 20. When the flange 20 is connected to the flange 19, the sealing gasket 21 is in close contact with the left side of the flange 20, achieving a seal on the adjustment device. The material of the sealing gasket 21 should have good elasticity and sealing performance, capable of withstanding a certain pressure without leakage.

[0034] Reference Figures 3 to 5 The right side of the corrugated hose 5 is fixedly connected to the left side of flange 9. A nut 6 is threaded onto the external thread of the threaded rod 4, which works in conjunction with the threaded rod 4 to fix its position. After adjusting the position of the threaded rod 4, tightening the nut 6 ensures tight contact with the bracket 8, preventing loosening or displacement of the threaded rod 4 during refrigeration operation. The right side of the threaded rod 4 contacts the left side of the expander spring 3, and the right side of the nut 6 contacts the left side of the bracket 8. The external sliding ring 19 is slidably connected to the inner wall of the annular cavity 17. The right side of the sealing gasket 21 contacts the left side of flange 10. Sliding blocks 15 are fixedly connected to both the upper and lower left sides of flange 10. A rack 16 is fixedly connected to the front side of the sliding block 15, meshing with the gear 12 inside flange 9. When flange 2 10 is connected to flange 1 9, sliding block 15 drives rack 16 to move, thereby driving gear 12 to rotate, realizing automatic adjustment of the sealing structure. Flange 1 9 has an inner cavity 14. The outer side of sliding block 15 is detachably connected to the inner wall of inner cavity 14. Rotating rods 11 are rotatably connected to the upper and lower sides of flange 1 9. Gear 12 is fixedly connected to the outer side of rotating rod 11 and meshes with rack 16. When flange 2 10 is connected to flange 1 9, rack 16 moves and drives gear 12 to rotate, thereby driving rotating rod 11 and sealing structure to adjust. Rotating handle 13 is fixedly connected to the outer side of rotating rod 11. The outer teeth of rack 16 mesh with the outer teeth of gear 12. Threaded posts 22 are threadedly connected to the upper and lower sides of flange 1 9. Rotating handle 23 is fixedly connected to the outer side of threaded posts 22.

[0035] Working principle: First, by inserting the sliding block 15 into the inner cavity 14, the sliding block 15 drives the rack 16 to move, which in turn drives the gear 12 to rotate. After the flange 2 10 contacts the sealing gasket 21, the sealing gasket 21 drives the sliding ring 20 to move, which in turn drives the sliding ring 19 to slide. The sliding ring 19 compresses the telescopic spring 18, and then the rotating handle 23 is rotated, which drives the threaded column 22 to move. After the threaded column 22 contacts the sliding block 15, the debugging device is sealed, thus preventing gas leakage and improving the accuracy of the test results. The separate Stirling refrigeration unit debugging device and the expander are assembled into one unit using the flange 9 and the threaded rod 4. By rotating the threaded rod 4, the threaded rod 4 can move back and forth linearly along the axial direction, which in turn drives the expander spring 3 to move linearly along the axial direction. Then, the optimal parameters are determined based on the real-time detection values ​​of the external detection device.

[0036] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
