[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This embodiment provides a high-efficiency intelligent cooler for a dryer, in which condensed water in the air is preliminarily processed to reduce the workload of a steam-water separator.

[0029] like Figure 1 and Figure 2 As shown, it includes a vertically arranged shell 1, the side wall of the shell 1 is provided with a first shell-side pipe 10 and a second shell-side pipe 11 connected to the inner cavity of the shell 1, wherein the first shell-side pipe 10 is located below the second shell-side pipe 11, and the inner cavity of the shell 1 is provided with a heat exchange tube group 3 which is vertically arranged and consists of a plurality of heat exchange tubes 34, and the top of the shell 1 is provided with a blocking shell 16 for blocking the inner cavity of the shell 1, wherein, as shown Figure 6 As shown, the inner wall of the blocking shell 16 is fixedly provided with a partition 161 which divides its inner cavity into an air inlet cavity 162 and an air outlet cavity 163 . The blocking shell 16 is provided with an air inlet pipe 164 connected to the air inlet cavity 162 , and an air outlet pipe 165 connected to the air outlet cavity 163 .

[0030] It is worth mentioning here that the two ends of the heat exchange tube 34 are connected, wherein the heat exchange tube group 3 and the bottom of the inner cavity of the shell 1 form a condensate collection chamber 14, and the heat exchange tube 34 can be used to make the condensate collection chamber 14 connected to the air inlet chamber 162 and the air outlet chamber 163 at the same time.

[0031] Through the above arrangement, compressed high-temperature air is transported to the inside of the air inlet chamber 162 through the air inlet pipe 164. At this time, the air flows vertically downward to the condensate collection chamber 14 through the heat exchange tube 34 connected to the air inlet chamber 162. The gas in the condensate collection chamber 14 flows vertically upward through the heat exchange tube 34 connected to the air outlet chamber 163 and flows out of the cooler through the air outlet pipe 165. The coolant is transported to the inner cavity of the shell 1 through the first shell-side pipe 10. At this time, the coolant flows out through the second shell-side pipe 11. In this process, the air in the heat exchange tube 34 exchanges heat with the coolant, and then the air in the air heat exchange tube 34 is cooled, so that the air is output in the form of low temperature.

[0032] It is worth noting here that the temperature of the air gradually decreases during the flow inside the heat exchange tube 34. At this time, the water vapor in the air forms condensed water in the heat exchange tube 34. Since the heat exchange tube 34 in the heat exchange tube group 3 is in a vertical state, the condensed water flows back along the inner wall of the heat exchange tube 34 to the condensed water gathering chamber 14 for accumulation, thereby realizing the preliminary treatment of the condensed water in the air and reducing the water vapor content in the exhaust gas of the cooler. Since the steam-water separator is located at the next workstation of the cooler, the water vapor entering the steam-water separator is reduced, thereby reducing the working load of the steam-water separator.

[0033] In order to discharge the water accumulated in the condensed water collection chamber 14 to the outside, in this embodiment, as shown in FIG. Figure 2 and Figure 4 As shown, the shell 1 is provided with a drain pipe 15 connected to the bottom wall of the condensate collection chamber 14, and a valve is installed on the drain pipe 15. By opening the valve, the water in the condensate collection chamber 14 can be discharged from the cooler.

[0034] Since the coolant enters the inner cavity of the shell 1 from the first shell-side pipe 10 and flows out of the cooler from the second shell-side pipe 11, the compressed gas passes through the heat exchange tube 34 of the heat exchange tube group 3. In order to prevent the gas from contacting the coolant, in this embodiment, as shown in FIG. Figure 5 and Figure 7 As shown, the heat exchange tube group 3 also includes a first tube sheet 31 and a second tube sheet 32, wherein a plurality of heat exchange tubes 34 are fixedly installed between the first tube sheet 31 and the second tube sheet 32. It is worth noting that the diameter of the first tube sheet 31 is larger than the tube diameter of the inner cavity of the shell 1, and the diameter of the second tube sheet 32 ​​is smaller than the tube diameter of the inner cavity of the shell 1. The second tube sheet 32 ​​is installed in the inner cavity of the shell 1. Figure 2 and Figure 4As shown, a supporting retaining ring 13 extending inwardly along and radially is fixedly provided on the side wall of the inner cavity of the shell 1, and the supporting retaining ring 13 is located below the first shell-side pipe 10. When the heat exchange tube group 3 is installed, the bottom wall of the second tube sheet 32 ​​abuts against the top wall of the supporting retaining ring 13, wherein the first tube sheet 31 is located on the outside of the shell 1 and between the top wall of the shell 1 and the bottom wall of the sealing shell 16, thereby preventing the gas from contacting the coolant.

[0035] In order to enhance the sealing performance between the shell 1 and the heat exchange tube group 3, in this embodiment, as shown in FIG. Figure 3 As shown, a downwardly recessed sealing ring groove 17 is provided on the top wall of the shell 1, and a sealing gasket 171 is installed in the sealing ring groove 17, wherein the sealing gasket 171 is made of rubber material, and the thickness of the sealing gasket 171 is greater than the depth of the sealing ring groove 17. During the installation process, the bottom wall of the first tube sheet 31 abuts against the top wall of the sealing gasket 171, and the bottom wall of the blocking shell 16 abuts against the top wall of the first tube sheet 31, and then the blocking shell 16 and the shell 1 are fixedly connected by a bolt assembly. At this time, the sealing gasket 171 is squeezed and elastically deformed, thereby improving the sealing between the heat exchange tube group 3 and the shell 1.

[0036] Here, the first tube sheet 31 blocks the bottom opening of the blocking shell 16, and the first tube sheet 31 abuts against the partition 161, thereby sealing the air inlet cavity 162 and the air outlet cavity 163. In order to realize the installation of the partition 161, in this embodiment, as shown in FIG. Figure 3 and Figure 5 As shown, the top wall of the first tube sheet 31 is provided with a downwardly recessed insertion groove 311 , and when the blocking shell 16 is installed, the partition plate 161 is inserted into the insertion groove 311 .

[0037] When a certain amount of condensed water exists in the condensed water collection chamber 14, the gas entering the condensed water collection chamber 14 from the heat exchange tube 34 is easy to contact with the condensed water, and the condensed water is blown back into the heat exchange tube 34, and discharged outward through the air outlet chamber 163 and the air outlet pipe 165 along with the air flow. In order to solve this problem, in this embodiment, as shown in FIG. Figure 2 , Figure 4 and Figure 5 As shown, the condensate collection chamber 14 is provided with a hemispherical air guide cover 2 with an upward opening, wherein the side wall of the hemispherical air guide cover 2 is provided with a retaining edge 21 extending radially outward, as shown in FIG. Figure 4 As shown, when the hemispherical air guide cover 2 is installed, the bottom wall of the retaining edge 21 abuts against the bottom wall of the supporting retaining ring 13 , and the bottom wall of the heat exchange tube group 3 abuts against the top wall of the retaining edge 21 .

[0038] Among them, the inner wall of the hemispherical air guide cover 2 is arc-shaped, and the bottom wall of the hemispherical air guide cover 2 is provided with a water collecting port 22. The hemispherical air guide cover 2 also includes a protective baffle 23 located directly below the water collecting port 22, wherein the protective baffle 23 is fixedly connected to the outer wall of the hemispherical air guide cover 2 through a column.

[0039] With the above settings, Figure 4 As shown, the gas flowing downward from the heat exchange tube 34 blows toward the inner wall of the hemispherical air guide cover 2, then rises upward along the curvature of the inner wall and flows from the heat exchange tube 34 to the air outlet cavity 163 and is discharged from the cooler from the air outlet pipe 165. The condensed water falling downward from the heat exchange tube 34 flows downward through the water gathering port 22 and accumulates at the bottom of the condensed water gathering cavity 14. At this time, the protective baffle 23 at the bottom of the water gathering port 22 can block the downward flow of the airflow, thereby reducing the risk of contact between air and accumulated water.

[0040] Under normal circumstances, the heat exchange tube group 3 is composed of a first tube sheet 31, a second tube sheet 32 ​​and a plurality of heat exchange tubes 34, wherein the first tube sheet 31 and the second tube sheet 32 ​​are located at both ends of the heat exchange tube 34, and the heat exchange tube 34 is welded to the first tube sheet 31 and the second tube sheet 32. When one of the heat exchange tubes 34 is damaged, the entire heat exchange tube group 3 needs to be replaced, and the heat exchange tube 34 cannot be disassembled.

[0041] Therefore, in this embodiment, in order to realize the replacement of the heat exchange tube 34, as shown in FIG. Figure 7 and Figure 8 The heat exchange tube group 3 further includes a support mechanism 33 for fixing the first tube sheet 31 and the second tube sheet 32, wherein the support mechanism 33 includes two support rods 331, and the two support rods 331 are fixedly installed between the first tube sheet 31 and the second tube sheet 32 ​​by bolts.

[0042] Specifically, Figure 7 and Figure 8 As shown, the first tube sheet 31 and the second tube sheet 32 ​​are both provided with countersunk holes, and bolts are passed through the countersunk holes and fixedly connected to the support rod 331, which can prevent the bolts from being higher than the end walls of the first tube sheet 31 and the second tube sheet 32. Specifically, the countersunk holes on the first tube sheet 31 are located in the bottom wall of the plug-in slot 311.

[0043] In order to facilitate the installation of the heat exchange tube 34, in this embodiment, Figure 8As shown, the second tube sheet 32 ​​is provided with a plurality of sedimentation grooves 321, and the first tube sheet 31 is provided with a guide pipe 312 aligned with the sedimentation grooves 321, wherein the guide pipe 312 connects the heat exchange tube 34 with the air inlet cavity 162 or the air outlet cavity 163, and a side wall at one end of the heat exchange tube 34 is provided with a limiting end cap 341 extending radially outward. When the heat exchange tube 34 is installed, the small diameter end of the heat exchange tube 34 is inserted into the first tube sheet 31 through the sedimentation groove 321, and the heat exchange tube 34 is connected to the guide pipe 312, and finally, the limiting end cap 341 is inserted into the sedimentation groove 321.

[0044] When the heat exchange tube 34 is installed in the sedimentation tank 321 of the second tube sheet 32, in order to prevent the heat exchange tube 34 from moving, the heat exchange tube group 3 also includes a positioning hole plate 35, wherein the positioning hole plate 35 is provided with a through hole aligned with the orifice of the heat exchange tube 34. When the heat exchange tube 34 is completely installed, the positioning hole plate 35 is fixed to the second tube sheet 32 ​​by bolts.

[0045] When the heat exchange tube group 3 is installed in the inner cavity of the shell 1 , the bottom wall of the positioning hole plate 35 abuts against the top wall of the retaining edge 21 .

[0046] In order to enhance the stability of the heat exchange tube 34, in the present embodiment, a sealing gasket 36 is provided on the outer side of the heat exchange tube 34. When the heat exchange tube 34 is installed, one end wall of the sealing gasket 36 abuts against the bottom wall of the sedimentation tank 321, and the other end wall of the sealing gasket 36 abuts against the limiting end cap 341.

[0047] In order to extend the flow path of the coolant in the inner cavity of the housing 1, in this embodiment, Figure 5 and Figure 7 As shown, the support mechanism 33 also includes a plurality of baffles 332 fixed on the support rods 331, wherein the baffles 332 are provided with through holes for the heat exchange tubes 34 to pass through, and two adjacent baffles 332 are staggered with each other. Here, the baffles 332 not only extend the flow path of the coolant, but also can utilize the baffles 332 to strengthen the strength of the heat exchange tubes 34 and prevent the heat exchange tubes 34 from deformation.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
