[0059] The moving tube plate 110 is movably connected with the first end of the shell body 130, that is, the moving tube plate 110 is configured to be movable along the shell body 130.

[0060] The fixed tube plate 120 is fixedly connected with the second end of the shell body 130; for example, the fixed tube plate 120 and the second end of the shell body 130 are fixedly connected by welding, bolt connection or the like. Optionally, the fixed tube plate 120 and the shell body 130 are sealingly connected by a sealing gasket, so as to improve the sealing performance between the fixed tube plate 120 and the shell body 130.

[0061] The moving end cover 400 is fixedly connected with the moving tube plate 110, and forms an inner chamber 410; for example, the moving end cover 400 and the moving tube plate 110 are fixedly connected by welding, bolt connection or the like. By fixedly connecting the moving end cover 400 and the moving tube plate 110, the moving end cover 400 and the moving tube plate 110 are simultaneously movable in the outer chamber 310 along with the expansion and contraction of the cooling pipe group 200. Optionally, the moving end cover 400 and the moving tube plate 110 are sealingly connected by a sealing gasket, so as to improve the sealing performance between the moving end cover 400 and the moving tube plate 110.

[0062] The cooling pipe group 200 is arranged in the shell body 130; along the axial direction of the cooling pipe group 200, the two ends of the cooling pipe group 200 are fixedly connected with the fixed tube plate 120 and the moving tube plate 110 respectively; that is, one end of the cooling pipe group 200 is fixedly connected with the fixed tube plate 120, and the other end of the cooling pipe group 200 is fixedly connected with the moving tube plate 110.

[0063] The cooling tube group 200 passes through the fixed tube plate 120 and the movable tube plate 110 respectively, and is in communication with the inner chamber 410.

[0064] In the embodiment, the air cooler is used for heat exchange between the first medium and the second medium, wherein the first medium flows inside the cooling tube group 200 and in the inner chamber 410, and the second medium flows outside the cooling tube group 200. For example, the second medium flows between the fixed tube plate 120 and the movable tube plate 110 outside the cooling tube group 200. Alternatively, the first medium is cooling water, and the second medium is high-temperature pressurized air.

[0065] In the embodiment, the cooling tube group 200 comprises a plurality of cooling tubes arranged side by side. Two ends of each cooling tube are fixedly connected with the movable tube plate 110 and the fixed tube plate 120 respectively.

[0066] Alternatively, the cooling tubes of the cooling tube group 200 are provided with fins. Alternatively, the fins are attached to the outer walls of the cooling tubes by means of a tube expander.

[0067] In the embodiment, the air cooler is provided with the movable end cover 400 in the outer chamber 310 formed by the shell 100 and the first end cover 300, and the movable end cover 400 is fixedly connected with the movable tube plate 110, and the movable tube plate 110 is fixedly connected with the cooling tube group 200, so that the movable end cover 400 and the movable tube plate 110 can freely move in the outer chamber 310 relative to the shell body 130 along with the expansion and contraction of the cooling tube group 200. When the air cooler is operated in a high-temperature and high-pressure working environment, the cooling tube group 200 can freely expand and contract, thereby avoiding or reducing thermal stress generated by the cooling tube group 200 during operation, greatly improving the service life of the cooling tube group 200, and avoiding or reducing the problem of sealing failure between the cooling tube group 200 and the fixed tube plate 120 and the movable tube plate 110 due to thermal expansion and contraction, thereby improving the service life of the air cooler to a certain extent.

[0068] Referring to Figure 4 , Figure 6 and Figure 7 , in an optional scheme of the embodiment, the movable end cover 400 is provided with an inner chamber medium discharging device 420 in communication with the inner chamber 410; the inner chamber medium discharging device 420 passes through and extends out of the first end cover 300. Through the inner chamber medium discharging device 420, water, gas or a mixture of water and gas in the inner chamber 410 can be discharged, so that the inner chamber 410 has a water and gas discharging function. In the embodiment, the inner chamber medium discharging device 420 passes through the outer chamber 310 and the first end cover 300 and extends out of the first end cover 300.

[0069] In order to ensure the sealing between the inner chamber medium discharging device 420 and the outer chamber 310, and between the outer chamber 310 and the outside atmosphere, referring to Figure 4 ,Figure 6 and Figure 7 As shown, in an optional embodiment, the inner cavity discharge medium device 420 includes a discharge medium body 421 and a sealing gasket 422.

[0070] One end of the discharge medium body 421 is fixedly connected to the movable end cover 400; for example, the discharge medium body 421 and the movable end cover 400 are integrally formed, or the discharge medium body 421 and the movable end cover 400 are fixedly connected by welding or screwing.

[0071] The other end of the discharge medium body 421 passes through and extends out of the first end cap 300; a plug 424 is detachably connected to the other end of the discharge medium body 421. The discharge medium body 421 has an inner cavity discharge medium through hole 423 communicating with the inner cavity 410, and the plug 424 cooperates with the inner cavity discharge medium through hole 423; water, gas, or a mixture of water and vapor can be discharged from the inner cavity 410 through the inner cavity discharge medium through hole 423, so that the inner cavity 410 has the function of draining and venting. By using the plug 424 to seal the inner cavity discharge medium through hole 423, the inner cavity 410 can be kept in a sealed state when the inner cavity 410 does not need to drain or vent.

[0072] Optionally, the sealing gasket 422 is fitted over the discharge medium body 421, and the sealing gasket 422 is fixedly connected to the side of the first end cap 300 away from the outer chamber 310. The sealing gasket 422 is used to better ensure the seal between the inner cavity discharge medium device 420 and the outer chamber 310, and between the outer chamber 310 and the outside atmosphere.

[0073] Optionally, a first row of media sealing rings 425 are provided between the sealing gasket 422 and the media discharge body 421; the first row of media sealing rings 425 are used to ensure the seal between the inner cavity media discharge device 420 and the outer cavity 310.

[0074] Optionally, a second row of medium sealing rings 426 is provided between the sealing gasket 422 and the first end cap 300, and the second row of medium sealing rings 426 is located on the outer periphery of the medium discharge body 421. The second row of medium sealing rings 426 ensures the seal between the outer chamber 310 and the outside atmosphere.

[0075] See Figure 7 As shown, in the optional embodiment, the medium discharge body 421 is connected to a threaded sleeve 427 on the medium discharge through hole 423 in the inner cavity, and the threaded sleeve 427 and the plug 424 are detachably connected.

[0076] Optionally, the hardness of the threaded sleeve 427 is greater than that of the media discharge body 421. By setting the threaded sleeve 427, damage to the threads after repeated disassembly and assembly of the plug 424 can be prevented, thereby improving the service life of the internal media discharge device 420 to a certain extent.

[0077] Optionally, the plug 424 is a bolt.

[0078] Optionally, the discharge medium body 421 is made of aluminum or aluminum alloy, or other materials.

[0079] Alternatively, the 427 threaded insert can be made of steel or other materials with high hardness.

[0080] See Figure 1 and Figure 4 As shown, in an optional embodiment, the first end cap 300 is provided with an external cavity discharge medium through hole that communicates with the external cavity 310; through the external cavity discharge medium through hole, water, gas or water vapor mixture of the external cavity 310 can be discharged, so that the external cavity 310 has drainage and exhaust functions.

[0081] Optionally, the external cavity discharge medium through hole is connected to an external cavity discharge medium plug 320; by using the external cavity discharge medium plug 320 to block the external cavity discharge medium through hole, the external cavity 310 can be kept in a sealed state when the external cavity 310 does not need to drain or vent.

[0082] Optionally, the external cavity discharge medium plug 320 can be a bolt or other structure.

[0083] See Figure 8 and Figure 9 As shown, in an optional embodiment, the interior of the cooling tube assembly 200 and the inner chamber 410 are used for the flow of the first medium; a second medium chamber is formed outside the cooling tube assembly 200 and between the fixed tube sheet 120 and the movable tube sheet 110 for the flow of the second medium.

[0084] The movable end cover 400 and the movable tube sheet 110 are provided with movable through holes 500. The movable through holes 500 penetrate the movable end cover 400 and the movable tube sheet 110, and connect the outer chamber 310 and the second medium chamber. The movable through holes 500 can be used to balance the air pressure between the outer chamber 310 and the second medium chamber, and can also discharge condensate in the second medium chamber to the outer chamber 310 through the movable through holes 500, and then discharge it through the outer medium discharge through hole of the outer chamber 310. Specifically, when the air cooler is running, the outer chamber 310 and the second medium chamber have the same air pressure, which can prevent certain components of the outer chamber 310 and the second medium chamber from being stressed due to pressure differences, and also facilitates the expansion and contraction of the movable end cover 400 and the movable tube sheet 110 with the cooling tube assembly 200; at the same time, when the air cooler is positioned appropriately, the movable through holes 500 can also drain condensate from the second medium chamber.

[0085] See Figure 4 , Figure 6 and Figure 9As shown, in the optional solution of the embodiment, in order to reduce the vibration of the movable end cover 400 and the movable tube plate 110 during the expansion and contraction, the outer circumferential surface of the movable end cover 400 is provided with a damping groove, a damping ring 600 is arranged in the damping groove, and part of the damping ring 600 protrudes out of the damping groove. By protruding part of the damping ring 600 out of the damping groove, when the movable end cover 400 expands and contracts with the cooling tube group 200, the movable end cover 400 does not directly contact the first end cover 300, but contacts the first end cover 300 through the damping ring 600, so that the damping ring 600 plays a damping role.

[0086] Optionally, the damping ring 600 abuts or clearance fits the first end cover 300; the damping ring 600 is configured to be movable relative to the first end cover 300 with the movable end cover 400. By abutting or clearance fitting the damping ring 600 with the first end cover 300, the resistance generated by the damping ring 600 can be reduced or avoided when the movable end cover 400 expands and contracts with the cooling tube group 200.

[0087] In the embodiment, in addition to the damping effect, the damping ring 600 also has a fixing and supporting effect, which can avoid mutual vibration and friction between the movable end cover 400 and the first end cover 300.

[0088] In the embodiment, the material of the damping ring 600 is rubber, silicone or other elastic material.

[0089] Referring to Figure 6 and Figure 9 As shown, in the optional solution of the embodiment, the inner circumferential surface of the first end cover 300 is provided with a chamfer groove 330; the chamfer groove 330 extends to the end surface of the first end cover 300 close to the shell 100. Through the chamfer groove 330, the rapid installation of the first end cover 300 can be effectively guaranteed.

[0090] Referring to Figures 1-6 As shown, in the optional solution of the embodiment, the air cooler further comprises a second end cover 700; the shell 100 comprises a second end corresponding to the first end.

[0091] The second end of the shell 100 is connected with the second end cover 700 and forms a second end cover chamber 710; for example, the shell body 130, the fixed tube plate 120 and the second end cover 700 are sequentially fixedly connected, for another example, the shell body 130 is directly fixedly connected with the second end cover 700, and for another example, the fixed tube plate 120 and the second end cover 700 are fixedly connected.

[0092] Optionally, the fixed tube plate 120 and the second end cover 700 form the second end cover chamber 710; the cooling tube group 200 communicates with the second end cover chamber 710.

[0093] As Figure 4As shown, in the optional solution of the embodiment, at least one partitioning member 800 is arranged on the inner chamber 410 and / or the chamber of the second end cover 700; that is, at least one partitioning member 800 is arranged on the inner chamber 410 or the chamber of the second end cover 700, or at least one partitioning member 800 is arranged on both the inner chamber 410 and the chamber of the second end cover 700.

[0094] The partitioning member 800 divides the inner chamber 410 or the chamber of the second end cover 700 into sub-chambers that are not communicated with each other, each of the sub-chambers is communicated with a plurality of cooling pipes corresponding to the cooling pipe group 200, so that the first medium flowing in the cooling pipe group 200 can flow in a zigzag shape; Figure 4 In the embodiment, the first medium flowing in the cooling pipe group 200 flows in a U shape, and the water inlet and the water outlet of the first medium can be arranged on the second end cover 700.

[0095] Optionally, part or all of the sub-chambers of the inner chamber 410 are communicated with an inner chamber medium discharging device 420.
