The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 and Figure 2 As shown, a refrigerated compressed air dryer includes: a housing 20, which is a rectangular box with a hollow interior; an inlet pipe 21 is fixedly connected to the top of the housing 20, which is cylindrical; and an outlet pipe 25 is also fixedly connected to the top of the housing 20, which is also cylindrical.

The top of the connecting pipe 24 can communicate with the bottom of the outlet pipe 25.

[0031] Evaporator 26 is fixedly connected to the bottom of the cavity of housing 20. The top of evaporator 26 can communicate with the bottom of air exchanger 23. A gas-water separator 27 is fixedly connected to the side wall of evaporator 26. The gas-water separator 27 is connected to evaporator 26 through a pipe. A drainer 28 is fixedly connected to the other side of gas-water separator 27. An opening is opened on the wall of housing 20 at the bottom of drainer 28. Drainer 28 can communicate with gas-water separator 27 through a pipe. The working layout of the cavity of housing 20 is consistent with the layout of the cavity in the prior art (publication number: CN218608694U). This is the prior art, so it will not be described in detail here.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a circulation structure is installed on the wall of the housing 20 for heat dissipation within the housing 20 cavity. The circulation structure includes: a hub chamber 30, a fan 34, a transition chamber 35, a heat exchange pipe 36, and a suction pipe 37. The hub chamber 30 is fixedly connected to the bottom left side of the housing 20, the fan 34 is rotatably connected to the cavity of the hub chamber 30, the transition chamber 35 is fixedly connected to the bottom right side of the housing 20, the heat exchange pipe 36 is fixedly connected to the top of the transition chamber 35, and the suction pipe 37 is fixedly connected to the end of the heat exchange pipe 36.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the hub chamber 30 and transition chamber 35 are hollow rectangular boxes. The interior of the hub chamber 30 can communicate with the interior of the casing 20, and the interior of the transition chamber 35 can also communicate with the interior of the casing 20. The heat exchange tube 36 is an L-shaped hollow round tube, and its bottom end is connected to the interior of the transition chamber 35. The heat exchange tube 36 can penetrate through the side wall of the outlet tube 25. The extraction tube 37 is a Z-shaped pipe, with one end connected to the heat exchange tube 36 and the other end extending to connect with the top of the hub chamber 30. The circulation structure also includes a support 33, a filter plate 31, and a mesh 32. The support 33 is fixed. The fan 34 is rotatably connected to the side wall of the support 33 inside the hub chamber 30. The other side wall of the support 33 is equipped with a motor for driving the fan 34 to rotate. The filter plate 31 is fixedly connected to the connection between the hub chamber 30 and the housing 20. The mesh 32 is opened on the side wall of the filter plate 31. The support 33 and the fan 34 are also set in the transition chamber 35. The same filter plate 31 and mesh 32 are also set at the connection between the transition chamber 35 and the housing 20. The filter plate 31 is rectangular and the mesh 32 is round. Multiple identical meshes 32 are opened on the wall of the filter plate 31.

[0034] In practical use, compressed air first enters the precooler 22 through inlet pipe 21, where it undergoes heat exchange with air or water to remove some of the heat. Then it enters the air exchanger 23, where it exchanges heat with the cold air that has already exited the evaporator 26 and been cooled to its pressure dew point, further reducing the temperature of the compressed air. Afterward, the compressed air enters the evaporator 26, which contains refrigerant, and exchanges heat with it, lowering the temperature of the compressed air to between zero and eight degrees Celsius. At this temperature, moisture in the air precipitates out and is separated by the air-water separator 27, then discharged through the drain 28 to the opening at the bottom of the casing 20. The dry, low-temperature air then enters the air exchanger 23 for heat exchange, and after its temperature rises, it is output through the outlet pipe 25 via the through pipe 24. During operation, the motor is turned on, driving the corresponding fan 34 to rotate. The fan 34 in the hub chamber 30 draws the air outward from the hub chamber 30, while the fan 34 in the transition chamber 35 draws the air into the housing 20. When the transition chamber 35 draws air through the fan 34, the air is drawn through the opening connecting the drawing pipe 37 and the hub chamber 30 to the heat exchange tube 36 and then into the transition chamber 35, and then into the housing 20. When the air is discharged from the outlet pipe 25, it will contact the wall of the heat exchange tube 36. The air passing through the heat exchange tube 36 will exchange heat with the air discharged through the outlet pipe 25. The filter plate 31 can filter the air entering the housing 20, thereby reducing the temperature of the air in the heat exchange tube 36.

[0035] In summary, by setting up a circulation structure, heat can be dissipated from the chamber 20 through circulating heat exchange, and when air enters the heat exchange tube 36, it can be cooled by the air ejected from the outlet tube 25, thus making this solution highly efficient in heat dissipation.

[0036] like Figure 1 and Figure 5 As shown, the left side wall of the hub chamber 30 is open. A side plate 40 is fixedly connected to the open side wall of the hub chamber 30. A through groove 41 is symmetrically opened on the side wall of the side plate 40. An arc plate 42 is fixedly connected to each through groove 41. The side plate 40 can cover the opening of the side wall of the hub chamber 30. The arc plate 42 is an arc-shaped plate. A rectangular gap is opened at the bottom of the arc plate 42.

[0037] In actual use, the air blown out by the fan 34 will be discharged from the rectangular gap at the bottom of the arc plate 42, which can blow away the impurities blocking the rectangular gap when it is discharged.

[0038] In summary, by setting up the arc plate 42 in conjunction with the fan 34, ventilation can be achieved while preventing the arc plate 42 from becoming clogged, thereby reducing the frequency of cleaning.

[0039] Working principle: First, compressed air enters the precooler 22 through inlet pipe 21, where it undergoes heat exchange with air or water, removing some of the heat energy. Then, it enters the air exchanger 23, where it exchanges heat with the cold air that has exited the evaporator 26 and been cooled to the pressure dew point, further reducing the temperature of the compressed air. Afterward, the compressed air enters the evaporator 26, which contains refrigerant, and exchanges heat with it, lowering the temperature of the compressed air to between zero and eight degrees Celsius. At this temperature, moisture in the air precipitates out and is separated by the air-water separator 27, then discharged through the drain 28 to the opening at the bottom of the casing 20. The dry, low-temperature air then enters the air exchanger 23 for heat exchange, and after its temperature rises, it enters the outlet pipe 25 through the through pipe 24 for output. During operation, the motor is turned on, driving the corresponding fan 34 to rotate. The fan 34 in the hub chamber 30 draws the air outward from the hub chamber 30, while the fan 34 in the transition chamber 35 draws the air into the housing 20. When the transition chamber 35 draws air through the fan 34, the air is drawn through the opening connecting the drawing pipe 37 and the hub chamber 30 to the heat exchange tube 36 and then into the transition chamber 35, and then into the housing 20. When the air is discharged through the outlet pipe 25, it will contact the wall of the heat exchange tube 36. The air passing through the heat exchange tube 36 will exchange heat with the air discharged through the outlet pipe 25. The filter plate 31 can filter the air entering the housing 20, thereby reducing the temperature of the air in the heat exchange tube 36.
