Description

Technical Field

[0001] This utility model relates to the technical field of air coolers, and in particular to a split-type tube-box air cooler. Background Technology

[0002] Chinese Patent CN214095119U discloses a novel split-type air cooler, comprising a frame, a fan, louvers, and tube bundles. The key feature is the inclusion of valves A, B, and C, and connecting pipes. The tube bundles are composed of at least a first unit tube bundle and a second unit tube bundle. One end of the connecting pipe is connected to the outlet pipe of the first unit tube bundle, and the other end is connected to the inlet pipe of the second unit tube bundle. Valve A is installed on the connecting pipe to connect the first and second unit tube bundles in series. Valve B is installed on the outlet pipe of the first unit tube bundle, and valve C is installed on the outlet pipe of the second unit tube bundle. By setting connecting pipes and valves between multiple tube bundles, and switching the flow path of the medium by opening and closing the valves, the heat exchange area is changed, thereby allowing for more targeted control of the medium outlet temperature of the air cooler in winter and summer, achieving full utilization of energy.

[0003] The aforementioned publicly available document, in paragraphs 0016 and 0017, states that "when the ambient temperature is high in summer, valves A5 and C7 are opened, and valve B6 is closed, connecting the first unit tube bundle 4-1 and the second unit tube bundle 4-2. At this time, the cooling circuit of the medium in the first unit tube bundle 4-1 and the second unit tube bundle 4-2 is a six-pass circuit, with the heat exchange area at its maximum under full load. The medium is discharged through the outlet pipe of the second unit tube bundle 4-2 to achieve the corresponding cooling effect. When the ambient temperature is low in winter, valve A5 is closed, and the first unit tube bundle 4-1 and the second unit tube bundle 4-2 are no longer connected in series, the tube bundle becomes a three-pass circuit, and the heat exchange area is halved. At this time, valve C7 is closed, and valve B6 is opened, and the cooling medium is discharged through the outlet pipe of the first unit tube bundle 4-1 to meet the cooling effect at lower ambient temperatures."

[0004] This involves controlling the heat exchange tube bundles via valves, thereby adjusting the heat exchange area to achieve the desired cooling effect. However, this setup requires additional heat exchange tube bundles within the entire split-type air cooler for valve adjustment, significantly increasing the number of heat exchange tube bundles and thus the cost. Improving the cooling effect without increasing the number of heat exchange tube bundles remains a technical challenge. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a split-type tube-box air cooler, which solves the technical problem that existing split-type air coolers require an increase in the number of heat exchange tube bundles to improve cooling effect, resulting in high production costs.

[0006] The technical solution of this utility model is implemented as follows: a split tube box air cooler includes a heat exchange tube bundle unit disposed on the tube box. The heat exchange tube bundle unit includes a first layer of heat exchange tube bundle and a second layer of heat exchange tube bundle. The second layer of heat exchange tube bundle is disposed parallel to the first layer of heat exchange tube bundle. A third layer of heat exchange tube bundle is disposed at an incline below the second layer of heat exchange tube bundle.

[0007] Preferably, the tube box includes a first tube box, a second tube box, and a third tube box. The first and second tube boxes are stacked along the height direction on one side of the split tube box air cooler, and the third tube box is disposed on the other side of the split tube box air cooler. The first and third tube boxes are connected by a first layer of heat exchange tube bundle and a second layer of heat exchange tube bundle, and the second and third tube boxes are connected by a third layer of heat exchange tube bundle.

[0008] Preferably, the third tube box is provided with a partition plate, which is located between the first heat exchange tube bundle and the second heat exchange tube bundle.

[0009] Preferably, the inclination angle of the third heat exchange tube bundle is between 0° and 20°.

[0010] Preferably, the lengths of the first heat exchange tube bundle, the second heat exchange tube bundle, and the third heat exchange tube bundle are all 3 to 3.5 meters.

[0011] Preferably, the first layer of heat exchange tube bundle, the second layer of heat exchange tube bundle, and the third layer of heat exchange tube bundle are all finned tubes.

[0012] Preferably, a pad is provided between the first pipe box and the second pipe box.

[0013] Preferably, the first tube box, the second tube box, and the third tube box all include a shell, with a plug plate connected to one side of the shell and a tube sheet connected to the other side. The shell, the plug plate, and the tube sheet are all sealed together to form a tube box. The first layer of heat exchange tube bundle, the second layer of heat exchange tube bundle, and the third layer of heat exchange tube bundle are all connected to the tube box through the tube sheet.

[0014] Preferably, the housing is provided with a positioning block, and the plug plate is provided with a positioning hole, the positioning block being adapted to the positioning hole.

[0015] Preferably, one end of the partition plate is sealed to the tube sheet and the other end is sealed to the plug plate.

[0016] The beneficial effects of this utility model are as follows: This utility model sets up a third layer of heat exchange tube bundle arranged at an angle below the second layer of heat exchange tube bundle. Without increasing the number of heat exchange tube bundles, the third layer of heat exchange tube bundle arranged at an angle greatly increases the air cooling area and heat dissipation efficiency, thereby improving the cooling effect of the split air cooler.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A split-type tube-and-box air cooler, such as Figure 1 As shown, the device includes a heat exchange tube bundle unit mounted on a tube box. The heat exchange tube bundle unit comprises a first layer of heat exchange tube bundles 4 and a second layer of heat exchange tube bundles 5. The second layer of heat exchange tube bundles 5 is arranged parallel to the first layer of heat exchange tube bundles 4, and a third layer of heat exchange tube bundles 6 is arranged at an angle below the second layer of heat exchange tube bundles 5. By arranging the third layer of heat exchange tube bundles 6 at an angle below the second layer of heat exchange tube bundles 5, without increasing the number of heat exchange tube bundles, the angled arrangement of the third layer of heat exchange tube bundles 6 significantly increases the air cooling area and heat dissipation efficiency, thereby improving the cooling effect of the split-type air cooler. This solves the technical problem of existing split-type air coolers requiring an increase in the number of heat exchange tube bundles to improve cooling performance, resulting in high production costs.

[0023] Example 2, based on Example 1, is a split-type tube-and-box air cooler, such as... Figure 1As shown, the tube box includes a first tube box 1, a second tube box 2, and a third tube box 3. The first tube box 1 and the second tube box 2 are stacked along the height direction on one side of the split tube box air cooler, and the third tube box 3 is located on the other side of the split tube box air cooler. The first tube box 1 and the third tube box 3 are connected by a first layer of heat exchange tube bundle 4 and a second layer of heat exchange tube bundle 5, and the second tube box 2 and the third tube box 3 are connected by a third layer of heat exchange tube bundle 6. In this split-type tube-and-tube air cooler, a first tube box 1 and a second tube box 2 are placed on one side, and a third tube box 3 is placed on the other side. The first tube box 1 and the second tube box 2 are stacked along their height. A first layer of heat exchange tube bundles 4 and a second layer of heat exchange tube bundles 5 are positioned between the first tube box 1 and the third tube box 3. The two ends of the first layer of heat exchange tube bundles 4 are sealed to both the first tube box 1 and the third tube box 3, respectively. The two ends of the second layer of heat exchange tube bundles 5 are also sealed to both the first tube box 1 and the third tube box 3, respectively. The second layer of heat exchange tube bundles 5 is located below the first layer of heat exchange tube bundles 4. The third layer of heat exchange tube bundles 6... Both ends are also sealed and connected to the second tube box 2 and the third tube box 3 respectively. The third heat exchange tube bundle 6 is located below the second heat exchange tube bundle 5. The second tube box 2 is provided with an inlet, and the third tube box 3 is provided with an outlet. When the medium flows into the third heat exchange tube bundle 6 along the inlet of the second tube box 2, then flows into the third tube box 3 along the third heat exchange tube bundle 6, then flows into the second heat exchange tube bundle 5, then flows into the first tube box 1 along the second heat exchange tube bundle 5, then flows into the first heat exchange tube bundle 4, then into the third tube box 3, and flows out along the outlet of the third tube box 3.

[0024] Example 3, based on Example 2, is a split-type tube-and-box air cooler, such as... Figure 1 As shown, the third tube box 3 is equipped with a baffle 7, which is located between the first heat exchange tube bundle 4 and the second heat exchange tube bundle 5. The baffle 7 prevents heat exchange between the first heat exchange tube bundle 4 and the second heat exchange tube bundle 5 within the third tube box 3, thus ensuring that the medium flowing out of the first heat exchange tube bundle 4 does not exchange heat with the medium flowing into the third tube box 3 from the second heat exchange tube bundle 5, thereby guaranteeing the cooling effect of the split-type tube box air cooler of this application. Furthermore, this design only requires one baffle 7 within the third tube box 3, resulting in a smaller number of baffles and significantly reduced production costs.

[0025] The partition board is a type of board made of materials such as fiber cement board, foam board and mineral wool board. The partition board has good heat insulation, fire resistance and water resistance. In addition, the fiber cement board and foam board in the partition board have good seismic performance and load-bearing capacity, which can effectively enhance the strength of the building structure.

[0026] Example 4, based on Example 3, a split-type tube-and-box air cooler, such as... Figure 1As shown, the tilt angle of the third heat exchange tube bundle 6 is between 0° and 20°. The tilt of the third heat exchange tube bundle 6 greatly increases the air cooling area, improves heat dissipation efficiency, and thus enhances the cooling effect of the split-type air cooler. However, when the tilt angle of the third heat exchange tube bundle 6 is too large, its length also increases significantly. When the tilt angle is 0°, the third heat exchange tube bundle 6 is arranged in parallel, without increasing the air cooling area; therefore, a tilt angle of 0° is not within the protection scope of this application. When the tilt angle of the third heat exchange tube bundle 6 is 20°, the air cooling area is greatly increased, but the length of the third heat exchange tube bundle 6 also increases significantly, resulting in higher production costs. Considering increasing the air cooling area and improving heat dissipation efficiency, a tilt angle of 20° for the third heat exchange tube bundle 6 is preferred.

[0027] Example 5, based on Example 4, a split-type tube-and-box air cooler, such as... Figure 1 As shown, the lengths of the first layer heat exchange tube bundle 4, the second layer heat exchange tube bundle 5, and the third layer heat exchange tube bundle 6 are all between 3 meters and 3.5 meters. Limiting the lengths of the first layer heat exchange tube bundle 4, the second layer heat exchange tube bundle 5, and the third layer heat exchange tube bundle 6 to between 3 meters and 3.5 meters avoids the situation where the production cost would be high if the lengths of the first layer heat exchange tube bundle 4, the second layer heat exchange tube bundle 5, and the third layer heat exchange tube bundle 6 were too long.

[0028] Example 6, based on Example 5, a split-type tube-and-box air cooler, such as... Figure 1 As shown, the first layer of heat exchange tube bundle 4, the second layer of heat exchange tube bundle 5, and the third layer of heat exchange tube bundle 6 are all finned tubes. Finned tubes are made by adding fins to the surface of the heat exchange tube bundle, thereby increasing the outer surface area of ​​the heat exchange tube bundle and thus improving the heat exchange efficiency.

[0029] Example 7, based on Example 6, a split-type tube-and-box air cooler, such as... Figure 1 As shown, a pad 8 is provided between the first tube box 1 and the second tube box 2. The pad 8 is provided to avoid mutual interference in heat exchange between the first tube box 1 and the second tube box 2. At the same time, the pad 8 also ensures the shock absorption effect of the first tube box 1 and avoids the vibration of the first tube box 1 to the second tube box 2.

[0030] Example 8, based on any one of Examples 3 to 7, a split-type tube-and-box air cooler, such as Figure 1 and Figure 2As shown, the first tube box 1, the second tube box 2, and the third tube box 3 all include a shell 9. A plug plate 10 is connected to one side of the shell 9, and a tube sheet 11 is connected to the other side. The shell 9, plug plate 10, and tube sheet 11 are all sealed together to form a tube box. The first layer heat exchange tube bundle 4, the second layer heat exchange tube bundle 5, and the third layer heat exchange tube bundle 6 are all connected to the tube box through the tube sheet 11. The shell 9, plug plate 10, and tube sheet 11 form a tube box for media exchange between the first layer heat exchange tube bundle 4, the second layer heat exchange tube bundle 5, and the third layer heat exchange tube bundle 6. The shell 9, plug plate 10, and tube sheet 11 are detachably connected by screws, facilitating disassembly and cleaning of the tube box.

[0031] Example 9, based on Example 8, a split-type tube-and-box air cooler, such as... Figure 1 and Figure 2 As shown, the housing 9 is provided with a positioning block 12, and the plug plate 10 is provided with a positioning hole 13. The positioning block 12 is adapted to the positioning hole 13. After the positioning block 12 and the positioning hole 13 are inserted and matched, the through hole on the plug plate 10 is coaxial with the through hole on the housing 9, which makes it easy to connect the plug plate 10 to the housing 9 with screws.

[0032] Example 10, based on Example 9, is a split-type tube-and-box air cooler, such as... Figure 1 As shown, one end of the partition plate 7 is sealed to the tube sheet 11, and the other end is sealed to the plug plate 10. The two ends of the partition plate 7 are sealed to the plug plate 10 and the tube sheet 11 respectively, ensuring that the third tube box 3 of the partition plate 7 is completely separated into two sealed spaces, and the medium in the two sealed spaces will not exchange heat.

[0033] In Example 10, the heat medium flows into the third heat exchange tube bundle 6 along the inlet of the second tube box 2, then into the third tube box 3 along the third heat exchange tube bundle 6, then into the second heat exchange tube bundle 5, then into the first tube box 1 along the second heat exchange tube bundle 5, and then into the first heat exchange tube bundle 4. The heat medium, after being cooled by heat exchange, returns to the third tube box 3 and flows out along the outlet of the third tube box 3.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
