Description

Technical Field

[0001] This invention belongs to the technical field of heat exchange equipment, and specifically discloses a modular quick-installation air cooler. Background Technology

[0002] Air coolers, as a common heat exchange device, are widely used in industries such as petrochemicals, power, and metallurgy. They cool high-temperature fluids inside the tubes through air convection, and have advantages such as water saving, environmental protection, and low operating costs.

[0003] Traditional air coolers typically use a fixed tube bundle and tube box connection structure. The heat exchange tubes are usually installed on the tube sheet by welding or bolting. When the heat exchange tubes need to be replaced or maintained, it is often necessary to disassemble the entire tube box or a large area of ​​tube bundle. The maintenance operation is cumbersome, the downtime is long, and it affects the continuity of production.

[0004] Therefore, those skilled in the art have proposed a modular quick-installation air cooler to solve the problems mentioned above. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to propose a modular quick-installation air cooler to solve the problem that the prior art is inconvenient to install and disassemble.

[0006] To achieve the above objectives, the present invention provides a modular quick-installation air cooler, comprising two mounting plates, with an inlet shell and an outlet shell fixedly connected to opposite sides of the two mounting plates respectively. The top of the inlet shell is connected to an inlet pipe, and the top of the outlet shell is connected to an outlet pipe. Limiting components are provided on the surfaces of the inlet shell and the outlet shell, and a heat exchange component is provided between the two mounting plates.

[0007] The heat exchange assembly includes a heat exchange tube disposed between two mounting plates. The surface of the heat exchange tube has evenly distributed annular grooves. The inner wall of the heat exchange tube is fixedly connected with several end-to-end partition plates. The cross-sectional shape of the partition plates is cross-shaped. Two adjacent partition plates are staggered. One end of the heat exchange tube is connected to the liquid outlet shell. The other end of the heat exchange tube is fixedly connected to a connecting pipe. The other end of the connecting pipe passes through the liquid inlet shell and is rotatably connected to a rotating block. Two symmetrically distributed limiting blocks are fixedly connected to the surface of the end of the heat exchange tube near the connecting pipe.

[0008] In the above technical solution, preferably, the surface of the connecting pipe is provided with uniformly distributed water inlet grooves, the inside of the connecting pipe is provided with a rotating shaft coaxial with the connecting pipe, one end of the rotating shaft is fixedly connected to one end of the rotating block, the inner side of the connecting pipe is provided with blocking blocks that are staggered with the water inlet grooves, and a connecting rod is fixedly connected between the blocking block and the rotating shaft.

[0009] In the above technical solution, preferably, the area of ​​the shielding block is larger than the opening area of ​​the water inlet tank.

[0010] In the above technical solution, preferably, a pull block is fixedly connected to the side of the rotating block away from the liquid inlet shell, two symmetrically distributed sliding grooves are formed on the surface of the rotating block, and a limiting groove is formed on the surface of the rotating block that communicates with the adjacent sliding groove.

[0011] In the above technical solution, preferably, a fixing column is fixedly connected to the inner wall of the end of the heat exchange tube away from the connecting tube, a through groove is opened on the surface of the fixing column, a retaining ring is fixedly connected to the inner wall of the heat exchange tube, a slip ring is slidably connected to the surface of the fixing column, a fixing ring is fixedly connected to the inner wall of the heat exchange tube, and a second spring is fixedly connected between the fixing ring and the slip ring.

[0012] In the above technical solution, preferably, the inner diameter of the retaining ring is larger than the inner diameter of the slip ring.

[0013] In the above technical solution, preferably, the limiting component includes a connecting ring fixedly connected to the side of the liquid outlet shell away from the mounting plate. The connecting ring is connected to the liquid outlet shell. A through hole communicating with the liquid outlet shell is opened on the surface of one side of the mounting plate. Two limiting grooves are opened on the inner wall of the through hole and are symmetrically distributed. The connecting ring is coaxially arranged with the through hole.

[0014] In the above technical solution, preferably, a sealing ring is fixedly connected to the inner side of the connecting ring, and two symmetrically distributed connecting blocks are provided on the surface of the connecting ring. A limit rod is fixedly connected to one side of the connecting block, and the other end of the limit rod passes through the connecting ring and is provided with an inclined surface. A first spring is fixedly connected to the surface of the connecting block, and the other end of the first spring is fixedly connected to the surface of the connecting ring.

[0015] In the above technical solution, preferably, the inner wall of the liquid outlet shell is provided with an insertion hole, a push tube is provided on the inner side of the insertion hole, a fixing plate is fixedly connected to the surface of the push tube, and the other side of the fixing plate is fixedly connected to the inner wall of the liquid outlet shell.

[0016] In the above technical solution, preferably, the outer diameter of the push tube matches the inner diameter of the retaining ring, and the inner diameter of the push tube is larger than the diameter of the fixed column.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting limit components and heat exchange components, the heat exchange tubes can be quickly installed and disassembled without the need for overall disassembly. Individual disassembly can be performed according to replacement needs, and the installation and disassembly methods are simple. Each heat exchange tube is an independent module that can be disassembled and replaced individually. When a heat exchange tube is damaged or blocked, it is not necessary to disassemble the entire tube bundle or large components, which significantly reduces maintenance workload, downtime, and replacement costs.

[0019] 2. The opening and closing of the water inlet tank can be controlled by rotating the rotating block to drive the blocking block. Closing it before installation and during disassembly effectively prevents liquid leakage, ensuring clean and safe operation. The slip ring and second spring installed inside the heat exchange tube automatically seal the liquid outlet when not installed. During installation, the push tube opens the slip ring and locks it in the through groove position, forming a reliable flow channel; during disassembly, the slip ring automatically resets and re-seals, realizing plug-and-play and plug-and-close at the liquid outlet.

[0020] 3. The annular grooves on the outer wall of the heat exchange tube form a continuous, integrated spiral fin structure, which effectively increases the heat dissipation area on the air side and enhances air turbulence, thereby improving the external convective heat transfer efficiency. The internal cross-shaped partition plates divide, turn, and remix the fluid multiple times, breaking the flow boundary layer, reducing the flow dead zone, making the fluid temperature distribution more uniform, strengthening the internal convective heat transfer, and improving the overall heat transfer efficiency.

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1-8 The modular quick-install air cooler shown includes two mounting plates 1. An inlet shell 102 and an outlet shell 101 are fixedly connected to opposite sides of the two mounting plates 1, respectively. An inlet pipe 104 is connected to the top of the inlet shell 102, and an outlet pipe 103 is connected to the top of the outlet shell 101. Limiting components 2 are provided on the surfaces of the inlet shell 102 and the outlet shell 101. A heat exchange component 3 is provided between the two mounting plates 1.

[0033] The heat exchange assembly 3 includes a heat exchange tube 301 disposed between two mounting plates 1. The surface of the heat exchange tube 301 is provided with uniformly distributed annular grooves 313. Several end-to-end partition plates 312 are fixedly connected to the inner wall of the heat exchange tube 301. The cross-sectional shape of the partition plates 312 is cross-shaped. Two adjacent partition plates 312 are staggered. One end of the heat exchange tube 301 is connected to the liquid outlet shell 101. The other end of the heat exchange tube 301 is fixedly connected to a connecting pipe 303. The other end of the connecting pipe 303 passes through the liquid inlet shell 102 and is rotatably connected to a rotating block 304. Two symmetrically distributed limiting blocks 302 are fixedly connected to the surface of the end of the heat exchange tube 301 near the connecting pipe 303.

[0034] The heat exchange tube 301 is designed for the passage of liquid. The liquid that needs to be cooled is introduced into the interior of the liquid inlet shell 102 through the liquid inlet pipe 104. After the cooperation of the heat exchange component 3 and the limiting component 2, the liquid can be introduced into the interior of the heat exchange tube 301 and finally into the liquid outlet shell 101, and finally discharged through the liquid outlet pipe 103.

[0035] In this process, the setting of the annular groove 313 enables the heat exchange tube 301 to form uniformly distributed heat dissipation fins on its surface, and the setting of the annular groove 313 can increase the air flow and the contact area with the heat exchange tube 301, thereby increasing the heat dissipation area.

[0036] The partition plate 312 allows the liquid to be separated into multiple streams after passing through it. Furthermore, since the partition plate 312 of the next layer is staggered with the previous partition plate 312, the separated liquid streams are further divided and mixed, making the liquid streams more uniform and the heat can be better dissipated through the heat exchange tube 301.

[0037] like Figures 1-8 As shown, the surface of the connecting pipe 303 is provided with evenly distributed water inlet grooves 308. The inside of the connecting pipe 303 is provided with a rotating shaft 311 coaxial with the connecting pipe 303. One end of the rotating shaft 311 is fixedly connected to one end of the rotating block 304. The inner side of the connecting pipe 303 is provided with blocking blocks 309 that are staggered with the water inlet grooves 308. A connecting rod 310 is fixedly connected between the blocking block 309 and the rotating shaft 311.

[0038] The area of ​​the shielding block 309 is larger than the opening area of ​​the water inlet trough 308.

[0039] A pull block 307 is fixedly connected to the side of the rotating block 304 away from the liquid inlet shell 102. Two symmetrically distributed sliding grooves 305 are opened on the surface of the rotating block 304. A limiting groove 306 connected to the adjacent sliding groove 305 is opened on the surface of the rotating block 304.

[0040] By rotating the rotating block 304, the rotating shaft 311 can be driven to rotate synchronously. In turn, under the action of the connecting rod 310, the shielding block 309 can be driven to rotate synchronously. By changing the position of the shielding block 309, the connection state of the water inlet tank 308 can be adjusted. When the water inlet tank 308 is open, the liquid that needs to be cooled can be introduced into the interior of the connecting pipe 303, and after being guided by the connecting pipe 303, it is injected into the interior of the heat exchange tube 301 for heat exchange treatment.

[0041] like Figures 1-8As shown, a fixing post 315 is fixedly connected to the inner wall of the end of the heat exchange tube 301 away from the connecting tube 303. A through groove 319 is opened on the surface of the fixing post 315. A retaining ring 314 is fixedly connected to the inner wall of the heat exchange tube 301. A slip ring 316 is slidably connected to the surface of the fixing post 315. A fixing ring 318 is fixedly connected to the inner wall of the heat exchange tube 301. A second spring 317 is fixedly connected between the fixing ring 318 and the slip ring 316.

[0042] The inner diameter of the retaining ring 314 is larger than the inner diameter of the slip ring 316.

[0043] When the heat exchange tube 301 is not installed, the slip ring 316 can be kept in close contact with the surface of the retaining ring 314 under the action of the second spring 317. During this process, the heat exchange tube 301 can be blocked, so that the liquid cannot be discharged from the end of the heat exchange tube 301 where the retaining ring 314 is installed.

[0044] like Figures 1-8 As shown, the limiting component 2 includes a connecting ring 203 fixedly connected to the side of the liquid outlet shell 101 away from the mounting plate 1. The connecting ring 203 is connected to the liquid outlet shell 101. A through hole 201 connected to the liquid outlet shell 101 is opened on the surface of one side of the mounting plate 1. Two limiting grooves 202 are opened on the inner wall of the through hole 201 and are symmetrically distributed. The connecting ring 203 is coaxially arranged with the through hole 201.

[0045] A sealing ring 204 is fixedly connected to the inner side of the connecting ring 203. Two connecting blocks 205 are provided on the surface of the connecting ring 203 and are symmetrically distributed. A limit rod 207 is fixedly connected to one side of the connecting block 205. The other end of the limit rod 207 passes through the connecting ring 203 and is provided with an inclined surface. A first spring 206 is fixedly connected to the surface of the connecting block 205. The other end of the first spring 206 is fixedly connected to the surface of the connecting ring 203.

[0046] An insertion hole 210 is provided on the inner wall of the liquid outlet shell 101. A push tube 209 is provided on the inner side of the insertion hole 210. A fixing plate 208 is fixedly connected to the surface of the push tube 209. The other side of the fixing plate 208 is fixedly connected to the inner wall of the liquid outlet shell 101.

[0047] The outer diameter of the push tube 209 matches the inner diameter of the retaining ring 314, and the inner diameter of the push tube 209 is larger than the diameter of the fixed post 315.

[0048] During installation, the heat exchange tube 301 is passed through the connecting ring 203, the through hole 201, and the insertion hole 210, allowing the heat exchange tube 301 to communicate with the liquid outlet shell 101. Simultaneously, during installation, the surface of the rotating block 304 presses against the inclined surface of the limiting rod 207, moving it away from the rotating block 304 and stretching the first spring 206. Once installed in place, the first spring 206 causes the limiting rod 207 to reset and insert into the sliding groove 305. At this point, the blocking block 309 blocks the water inlet tank 308 to prevent liquid from entering during installation. If the body leaks, rotate the rotating block 304 to adjust the shielding block 309 so that it no longer blocks the water inlet tank 308. At the same time, the limiting rod 207 can slide along the inner wall of the slide groove 305 until it moves to the limiting groove 306. Under the action of the first spring 206, it can be inserted into the limiting groove 306 as a whole, thus completing the adjustment. The operator can judge whether the shielding block 309 is adjusted in place by observing the height of the connecting block 205. The cooperation between the limiting groove 306 and the limiting rod 207 can limit the position of the heat exchange tube 301.

[0049] During installation, the push tube 209 can be inserted into the inner side of the retaining ring 314 to push the slip ring 316 along the surface of the fixed column 315 until it is installed in place. After that, the slip ring 316 moves to the middle of the opening of the through groove 319. Since the inner diameter of the push tube 209 is larger than the diameter of the fixed column 315, it can ensure that the flowing liquid passes through the through groove 319, bypasses the slip ring 316, enters the interior of the push tube 209, and is then introduced into the interior of the liquid shell 101 and discharged through the liquid outlet pipe 103.

[0050] Working principle: The heat exchange tube 301 is designed for liquid passage. The liquid to be cooled is introduced into the liquid inlet shell 102 through the liquid inlet pipe 104. After the cooperation of the heat exchange component 3 and the limiting component 2, the liquid is guided into the heat exchange tube 301 and finally into the liquid outlet shell 101, and then discharged through the liquid outlet pipe 103. During this process, the annular groove 313 enables the formation of uniformly distributed heat dissipation fins on the surface of the heat exchange tube 301. The annular groove 313 also increases the airflow and the contact area between the airflow and the heat exchange tube 301, thus increasing the heat dissipation area. At the same time, the partition plate 312 causes the liquid flow to be divided and mixed multiple times, making the liquid flow more uniform and the heat dissipation better through the heat exchange tube 301. The heat exchange component 3 and the limiting component 2 enable the heat exchange tube 301 to be quickly installed and disassembled. Operators can install and disassemble the heat exchange tube 301 individually, thus achieving individual replacement.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
