Description

Technical Field

[0001] This invention relates to the field of refrigeration and air conditioning, and more specifically to a water-cooled condenser using rotary perturbation. Background Technology

[0002] In large-scale refrigeration and air conditioning systems, such as ammonia refrigeration systems, vertical water-cooled condensers are widely used. The high-temperature and high-pressure gas discharged from the refrigeration compressor enters the condenser, where the refrigerant exchanges heat with the cooling water outside the heat exchange tube, releasing heat and condensing. The condensed liquid occupies the space of the heat exchange tube or accumulates on the surface of the heat exchange tube, preventing the surface of the heat exchange tube from fully exchanging heat with the cooling water outside the tube. This leads to a decrease in the heat transfer performance of the condenser, an increase in the condensation temperature, an increase in the pressure ratio of the refrigeration compressor, a decrease in the performance of the refrigeration system, and an increase in energy consumption. Summary of the Invention

[0003] The purpose of this invention is to address the technical deficiencies in the existing technology by providing a rotary perturbation water-cooled condenser for the refrigeration and air conditioning field, thereby solving the problem of efficient heat transfer in vertical water-cooled condensers, improving the performance of refrigeration systems, and saving energy.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A rotating perturbation water-cooled condenser includes a cylinder connected to tube sheets at both ends, and at least one electrically driven, closed heat exchanger cylinder arranged in the cylinder and concentric with the cylinder via the tube sheets, the heat exchanger cylinder rotating in conjunction with the tube sheets; the outer side of the tube sheets has end caps, a first end cap connected to a cooling water inlet pipe and a refrigerant inlet pipe, and a second end cap connected to a cooling water outlet pipe and a refrigerant liquid pipe; the refrigerant inlet pipe is connected to the gas inlet pipe of the heat exchanger cylinder, the refrigerant liquid pipe is connected to the outlet of a liquid collecting pipe, the inlet of the liquid collecting pipe is connected to the outlet of the drain pipe at the bottom of each heat exchanger cylinder, and through holes for cooling water flow are formed on the tube sheets.

[0006] The heat exchange cylinders are multiple and concentrically arranged, with their inner diameters decreasing sequentially. One end of each heat exchange cylinder is fixed to a support to form a rotating whole. The multiple heat exchange cylinders are connected by radially arranged connecting pipes to allow the refrigerant gas to enter the outer heat exchange cylinder from one end, pass through the middle heat exchange cylinder, and then enter the inner heat exchange cylinder, while the refrigerant liquid is discharged from the other end.

[0007] The air inlet pipe is connected to the outer heat exchange cylinder, the refrigerant liquid pipe is connected to the outlet of the liquid collection pipe through a telescopic pipe, and the inlet of the liquid collection pipe is connected to the outlet of the drain pipe at the bottom of each heat exchange cylinder.

[0008] The outer heat exchange cylinder meshes with a gear on the motor output shaft via a gear mounted on its outer circular surface, and the motor is mounted on one side of the first end cap.

[0009] The cooling water inlet pipe is located on the side wall of the first end cap; the cooling water outlet pipe is located on the side wall of the second end cap.

[0010] The other end of the refrigerant inlet pipe is connected to the exhaust pipe of the refrigeration compressor, and the other end of the refrigerant liquid pipe is connected to the inlet of the throttling and pressure-reducing element.

[0011] The first end cap and the second end cap are welded to the outer surfaces of the first tube sheet and the second tube sheet, respectively, and the two ends of the cylinder are welded to the inner surfaces of the first tube sheet and the second tube sheet, respectively.

[0012] The rotating disturbance water-cooled condenser of the present invention utilizes a motor to drive the annular channel heat exchange cylinder to rotate. Under the action of centrifugal force, the liquid inside the heat exchange cylinder adheres to the inner wall of the heat exchange cylinder and flows to the bottom of the heat exchange cylinder under gravity, and is led out through the drain pipe. At the same time, the rotating heat exchange cylinder increases the disturbance of the cooling water flowing outside the tube, enhances the heat transfer effect between the refrigerant inside the heat exchange cylinder and the cooling water outside the tube, and improves the performance of the refrigeration system.

Figure 2-3 As can be seen above, the opening at the top of the tube is welded to one end of the air inlet pipe 12, and the other end of the air inlet pipe 12 is welded to the refrigerant inlet pipe 9 through the second telescopic hose 11. The refrigerant inlet pipe 9 passes through the central opening on the first end cap 7 and is sealed to the central opening, and can rotate relative to it to form a rotating sealing connection structure. The opening at the end of the first heat exchange cylinder 14 that extends into the second end cap 22 near the outer wall of the inner ring surface is welded to one end of the first connecting pipes 2-1 and 2-2. The other end of the first connecting pipes 2-1 and 2-2 is welded to the opening at the second heat exchange cylinder 15 near the outer wall of the outer ring surface of the end of the second end cap 22. The opening at the second heat exchange cylinder 15 near the outer wall of the inner ring surface of the end of the first end cap 7 is welded to one end of the second connecting pipes 3-1 and 3-2. The other end of the second connecting pipes 3-1 and 3-2 is welded to the opening at the third heat exchange cylinder 16 near the outer wall of the outer ring surface of the end of the first end cap 7.

The second tube sheet through holes 17 and the first tube sheet through holes 4 can be rectangular holes or other geometric shapes, and the number can be one or more, whichever is more specific.

[0022] In this invention, the main shaft 10 is connected to the motor 8, and the other end of the main shaft 10 is fixed with an external tooth (not shown, but can be deduced from...). Figure 1As can be seen above, the main shaft 10 rotates under the drive of the motor 8. The external teeth on the main shaft 10 mesh with the external teeth on the first heat exchange cylinder 14, thereby driving the heat exchange cylinder to rotate synchronously.

[0023] In this invention, the motor 8 is fixed on the first end cap 7, specifically on one side of the end face.

[0024] It should be noted that in this invention, the first heat exchange cylinder 14, the second heat exchange cylinder 15, and the third heat exchange cylinder 16 can be heat exchange cylinders with smooth surfaces or heat exchange cylinders with low ribs on their surfaces.

[0027] When the refrigeration system is running, the gas discharged from the refrigeration compressor enters the annular channel of the first heat exchanger 14 through the refrigerant inlet pipe 9, the second telescopic hose 11, and the inlet pipe 12. It then enters the annular channel of the second heat exchanger 15 through the first connecting pipe 2, and finally enters the annular channel of the third heat exchanger 16 through the second connecting pipe 3. The motor 8 drives the first heat exchanger 14 via the external gears of the main shaft 10. The heat exchanger connecting frame 13 drives each heat exchanger to rotate. Under the action of centrifugal force, the first heat exchanger 14, the second... The condensed liquid inside heat exchanger 15 and the third heat exchanger 16 adheres to the inner wall of the outer annular surface of the heat exchanger and enters the liquid collection pipe 27 through the first drain pipe 24, the second drain pipe 25 and the third drain pipe 26. The liquid in the liquid collection pipe 27 goes through the liquid outlet pipe 19, the first telescopic hose 20 and the refrigerant liquid pipe 21 to the throttling and pressure reducing element. The cooling water enters the annular channel of the cylinder 1, the first heat exchanger 14, the second heat exchanger 15 and the third heat exchanger 16 through the cooling water inlet pipe 6 and flows out from the cooling water outlet pipe 18.
