Description

Technical Field

[0001] The utility model relates to the technical field of cold water circulation machines, in particular to a high-precision air-cooled vortex-type cooling water circulation machine. Background Art

[0002] Cooling water circulation units, also known as chillers or chillers, primarily utilize air or water cooling. Scroll-type air-cooled chillers offer cooling capacities ranging from 27.8kW to 284.5kW and heating capacities from 29kW to 303.5kW, meeting diverse load requirements in various applications. These units feature a compact structure, a small footprint, and a simple piping design, requiring only external water pipe connections for easy installation and maintenance. They are available in both monolithic and modular configurations. Modular units, comprised of 2 to 8 modules, offer high cooling capacity, redundant backup, and intermittent operation.

[0003] However, when the scroll-type air-cooled chiller is working, the internal compressor, water pump, fan and other electrical appliances are prone to vibration, and the chiller needs to be connected to external pipelines. The vibration amplitude of the internal pipeline of the chiller is different from that of the external pipeline, resulting in the connection point between the internal pipeline of the chiller and the external pipeline being subjected to greater force, affecting the service life of the connection structure. Over time, it is easy to cause the connection position to break and leak. Utility Model Content

[0013] Furthermore, the diameter of one end of the first water pipe and the inner diameter of the fixing frame are both larger than the diameter of one end of the second water pipe.

[0014] By adopting the above technical solution, the first water pipe and the second water pipe can move relative to each other, avoiding the phenomenon that the rigid connection between the two is caused by fatigue damage caused by vibration of the connection point due to different amplitudes.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] Example 1:

[0038] The inner ring of the fixing frame 10 is respectively connected with the first buffer seal 14, the second buffer seal 15 and the third buffer seal 16. The fixing frame 10, the first buffer seal 14, the second buffer seal 15 and the third buffer seal 16 are each provided with four groups. Two fixing frames 10, the first buffer seal 14, the second buffer seal 15 and the third buffer seal 16 form a group. The first buffer seal 14, the second buffer seal 15 and the third buffer seal 16 are all made of FLS fluorosilicone rubber. Firstly, they play a sealing role to avoid water leakage. Secondly, they play a buffering role to avoid the second water pipe 9 colliding with the first water pipe 8 or the fixing frame 10 and causing structural damage. Moreover, the first buffer seal 14, the second buffer seal 15 and the third buffer seal 16 are all FLS fluorosilicone rubber, which has good high and low temperature resistance, and avoids the high temperature of the return hot water and the low temperature of the output cold water causing the sealing failure.

[0039] A first reinforcing rib 12 is fixed to the top of the fixing frame 10, and a second reinforcing rib 13 is fixed to the upper surface and the upper back of the fixing frame 10. A plurality of first reinforcing ribs 12 and second reinforcing ribs 13 are provided, and the plurality of first reinforcing ribs 12 and second reinforcing ribs 13 are distributed in a circular array. The first reinforcing ribs 12 and second reinforcing ribs 13 increase the wall thickness of the fixing frame 10, thereby increasing the structural strength of the fixing frame 10 and preventing the fixing frame 10 from being deformed and stretched due to the displacement of the first water pipe 8 and the second water pipe 9.

[0040] Bolts 11 are passed through the upper and lower sides of the fixing frame 10. The two fixing frames 10 are disassembled and connected by the bolts 11. The staff puts a set of fixing frames 10 between the first water pipe 8 and the second water pipe 9 and passes through and tightens the bolts 11 to complete the limiting operation.

[0041] See Figure 1 and Figure 2 In the above embodiment, an air outlet 3 is provided on the top of the chiller body 1, and an air inlet 2 is provided above the outer surface of the chiller body 1. When the chiller body 1 is working, cooling air enters from the air inlet 2 and is discharged from the air outlet 3, thereby dissipating heat to the internal scroll compressor unit, and then cooling the circulating water through the scroll compressor unit; an inspection door 4 is hinged at the bottom of the outer surface of the chiller body 1 to facilitate maintenance of the scroll compressor inside the chiller body 1.

[0042] Example 2:

[0043] On the basis of the above embodiment 1, in order to reduce vibration, the following settings are now adopted.

[0044] See Figure 1 and Figure 2 In the above embodiment, a bracket 5 is fixed to the bottom of the chiller body 1, an inner spring damper 6 is installed at the bottom of the bracket 5, and a foot pad 7 is connected to the bottom of the inner spring damper 6.

Then the staff puts a set of fixing frames 10 between the first water pipes 8 and the second water pipes 9 and passes through and tightens the bolts 11 to complete the limiting operation;

[0046] When the chiller body 1 is working, cooling air enters from the air inlet 2 and is discharged from the air outlet 3, thereby dissipating heat to the internal scroll compressor unit, and then the circulating water is cooled by the scroll compressor unit. When the compressor, water pump, fan and other electrical appliances inside the chiller body 1 vibrate, the first water pipe 8 and the second water pipe 9 can move relative to each other to avoid the rigid connection between the two, which causes the connection point to be fatigued and damaged due to the vibration due to different amplitudes. At the same time, the second water pipe 9 is flexibly connected to the fixed frame 10 and the first water pipe 8 through the first buffer seal 14, the second buffer seal 15 and the third buffer seal 16. Firstly, it plays a sealing role to avoid water leakage, and secondly, it plays a buffering role to avoid The second water pipe 9 is prevented from colliding with the first water pipe 8 or the fixing frame 10 to cause structural damage, and the first buffer seal 14, the second buffer seal 15 and the third buffer seal 16 are all FLS fluorosilicone rubber, which has good high and low temperature resistance, and avoids the high temperature of the return hot water and the low temperature of the output cold water causing sealing failure. The wall thickness of the fixing frame 10 is increased by the first reinforcing rib 12 and the second reinforcing rib 13, thereby increasing the structural strength of the fixing frame 10, and avoiding the deformation and opening of the fixing frame 10 due to the displacement of the first water pipe 8 and the second water pipe 9; and the vibration of the chiller body 1 is reduced by the internal spring damper 6, thereby reducing the vibration of the pipeline and extending the service life of the pipeline connection point.
