[0003] The adjacent cooling pipes in the air cooler are connected by a welded elbow pipe, and the flow of high-temperature medium will impact the welded position, causing leakage of high-temperature medium.

[0004] The air cooler is installed with a fan at the bottom to blow in ambient air, and the air flow is constant and the flow direction is single, which cannot adapt to the situation of changes in flow and temperature of high-temperature medium.

[0005] It should be noted that the information disclosed in the above BACKGROUND section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is to provide an air cooler with adjustable air direction and an adjusting method thereof, to solve the problem that the air flow is constant and the flow direction is single in the prior art, which cannot adapt to the situation of changes in flow and temperature of high-temperature medium.

[0007] To achieve the above-mentioned purpose, the technical solutions of the present application are as follows: An air cooler with adjustable air direction; comprises an air cooling cylinder, an inlet structure swingingly arranged at the inlet of the air cooling cylinder, a blowing device arranged at the inlet of the inlet structure, a coil pipe stacked and laid in the air cooling cylinder, an intermediate cylinder arranged in the air cooling cylinder, and an exhaust mechanism for exhausting gas in the air cooling cylinder; wherein the inlet structure surrounds the air cooling cylinder and is tangent to the air cooling cylinder; the exhaust mechanism is rotationally arranged between the air cooling cylinder and the intermediate cylinder, and opens and closes the outlet of the air cooling cylinder and the intermediate cylinder.

[0008] Further technical solutions are that the inlet structure comprises a base, a swing frame for arranging the blowing device, and an extension channel arranged around the swing frame; wherein the swing frame is slidingly arranged on the base; the swing frame is swingingly connected to the inlet of the air cooling cylinder; the extension channel connects the edge of the inlet of the air cooling cylinder.

[0009] Further technical solutions are that the coil pipe comprises fins, pipe racks stacked and laid up and down, a pipe laid in a spiral manner on the pipe racks, and a sub-pipe for connecting adjacent pipes; wherein the sub-pipe is distributed along the spiral curvature; the fins are wound on the pipe and the sub-pipe.

[0010] Further technical solutions are that the exhaust mechanism comprises an inner ring frame rotatably arranged on the intermediate cylinder and an outer ring frame rotatably arranged in the air cooling cylinder; the inner ring frame and the outer ring frame are slidably connected with each other; the inner ring frame rotates to open and close the intermediate cylinder inlet, and the outer ring frame rotates to open and close the air cooling cylinder outlet.

[0011] Further technical solutions are that the exhaust mechanism further comprises a curtain slidably connected on the inner ring frame and the outer ring frame; the curtain opens and closes the inner ring frame and the outer ring frame to guide the gas flow to a preset direction.

[0012] Further technical solutions are that the air cooler further comprises a sensor for detecting the temperature of the medium in the coil; the sensor is electrically connected with the inlet structure, the air blowing device and the exhaust mechanism.

[0013] An adjusting method of an air cooler with adjustable air direction, comprising the following steps: A starting step: medium flows into the coil, and a half-open mode or a full-open mode is switched according to the flow of the medium; the air blowing device is started to blow gas into the air cooling cylinder, the gas contacts the coil, the gas rises along the spiral in the air cooling cylinder, and the heat of the medium is taken out; The half-open mode comprises the following steps: the curtain closes part of the positions of the inner ring frame and the outer ring frame to separate the air cooling cylinder; the inner ring frame and / or the outer ring frame rotates to open the air cooling cylinder outlet and / or the intermediate cylinder outlet; The full-open mode comprises the following steps: the curtain opens the positions of the inner ring frame and the outer ring frame; the inner ring frame and the outer ring frame rotate to close the air cooling cylinder outlet and the intermediate cylinder outlet; An adjusting step: the sensor detects the temperature of the medium, the swing frame moves along the base to adjust the gas inflow angle; the temperature of the medium is positively correlated with the inflow angle.

[0014] Further technical solutions are that in the full-open mode: when the sensor detects that the temperature of the medium exceeds a preset range, the outer ring frame rotates to open the air cooling cylinder outlet, and external gas is sucked into the air cooling cylinder.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) When the angle between the inlet structure and the air-cooled cylinder is small, the gas flows spirally along the edge of the air-cooled cylinder and gradually rises. The gas and the coil have less contact, and the air-cooling heat dissipation effect is limited. It can be used for air-cooling heat dissipation of low-temperature media. When the angle between the inlet structure and the air-cooled cylinder 1 is large, the gas moves closer to the inside of the air-cooled cylinder, flows spirally and gradually rises. The gas and the coil have more contact, and the air-cooling heat dissipation effect is better. It can be used for air-cooling heat dissipation of high-temperature media. When the medium flow rate is high, the exhaust mechanism closes the outlet of the air-cooled cylinder and the intermediate cylinder. The blowing device blows in the gas, and the gas flows spirally from the bottom of the air-cooled cylinder to the top of the air-cooled cylinder and is discharged. The gas and all the coils are in contact and the contact time is long, thus completing the air-cooling heat dissipation of high-flow-rate media. When the medium flow rate is low, the exhaust mechanism rotates to open the outlet of the air-cooled cylinder and the intermediate cylinder, and the exhaust mechanism itself closes. The blowing device blows in the gas, and the gas flows spirally from the bottom of the air-cooled cylinder to the outlet position and is discharged from the outlet. The gas and some of the coils are in contact and the contact time is short, thus completing the air-cooling heat dissipation of low-flow-rate media.

[0016] (2) The secondary pipe is used to connect the pipes on different pipe racks; the pipe bending process has fewer welding points, the medium flows spirally in the pipe and has little impact on the inner wall of the pipe, and there will be no leakage at the welding point; the secondary pipe is distributed along the spiral curvature, and the pipe and the secondary pipe are connected by welding, so the medium can flow smoothly and reduce the impact on the welding position.

[0017] (3) A shielding cloth is installed at positions 63a, 63b, 63c and 63d. The direction of gas flow is changed by controlling the opening and closing of the shielding cloth at each position. The rotation of the second frame plate realizes the extension and retraction of the hinge. The second frame plate supports the shielding cloth and improves the shielding cloth's resistance to gas impact. Attached Figure Description

Detailed Implementation

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0028] Figure 1 A schematic diagram of the air cooler with adjustable airflow direction in the first embodiment of the present invention is shown. Figure 2 It shows Figure 1 A top-down enlarged view of the central inlet structure and the blowing device. Figure 3 It shows Figure 2 Enlarged front view of the central gear. (Combined with...) Figures 1-3 As shown, the present invention discloses an air cooler with adjustable airflow direction, comprising: an air cooler cylinder 1, an inlet structure 2 oscillatingly disposed at the inlet of the air cooler cylinder 1, a blower device 3 arranged at the inlet of the inlet structure 2, a coil 4 stacked and laid inside the air cooler cylinder 1, an intermediate cylinder 5 disposed vertically inside the air cooler cylinder 1, and an exhaust mechanism 6 for discharging gas from inside the air cooler cylinder 1.

[0029] The air-cooled cylinder 1 is arranged vertically, with its bottom sealed and its top open for venting gas. An intermediate cylinder 5 is coaxially arranged inside the air-cooled cylinder 1, with its bottom sealed and its top open for venting gas.

[0030] An inlet 111 is formed on the air-cooled cylinder 1, with the inlet 111 extending vertically, and several inlets 111 are distributed around the air-cooled cylinder 1. An inlet structure 2 surrounds the air-cooled cylinder 1 and is tangential to it. The inlet structure 2 is installed at the inlet 111. A blowing device 3 blows gas into the air-cooled cylinder 1, and the gas flows spirally inside the air-cooled cylinder 1 and gradually rises before being discharged from the top of the air-cooled cylinder 1.

[0031] When the angle between the inlet structure 2 and the air-cooled cylinder 1 is small, the gas flows spirally along the edge inside the air-cooled cylinder 1 and gradually rises. The gas has less contact with the coil 4, and the air-cooling effect is limited. It can be used for air-cooling of low-temperature media.

[0032] When the angle between the inlet structure 2 and the air-cooled cylinder 1 is large, the gas moves closer to the interior of the air-cooled cylinder 1, flows in a spiral and gradually rises. The gas has more contact with the coil 4, resulting in better air-cooling performance, which can be used for air-cooling of high-temperature media.

[0033] The outlet of air-cooled cylinder 1 is located in the middle of air-cooled cylinder 1, and the outlet of intermediate cylinder 5 is located in the middle of intermediate cylinder 5. The exhaust mechanism 6 is rotatably arranged between air-cooled cylinder 1 and intermediate cylinder 5 to open and close the outlets of air-cooled cylinder 1 and intermediate cylinder 5.

[0034] The coils 4 are arranged in several groups and distributed on the upper and lower sides of the exhaust mechanism 6. The exhaust mechanism 6 can be closed or opened. When the exhaust mechanism 6 is open, the gas at the bottom of the air-cooled cylinder 1 can be discharged from the top of the air-cooled cylinder 1 through the exhaust mechanism 6. When the exhaust mechanism 6 is closed, the gas at the bottom of the air-cooled cylinder 1 is discharged through the outlets of the air-cooled cylinder 1 and the intermediate cylinder 5.

[0035] When the medium flow rate is high, the exhaust mechanism 6 closes the outlets of the air-cooled cylinder 1 and the intermediate cylinder 5. The blowing device 3 blows in gas, which spirals up from the bottom of the air-cooled cylinder 1 to the top and is discharged. The gas comes into contact with all the coils 4 for a relatively long time, thus completing the air-cooling heat dissipation of the high-flow-rate medium.

[0036] When the medium flow rate is low, the exhaust mechanism 6 rotates to open the outlets of the air-cooled cylinder 1 and the intermediate cylinder 5, and the exhaust mechanism 6 itself closes. The blowing device 3 blows in gas, which spirals up from the bottom of the air-cooled cylinder 1 to the outlet position and is then discharged from the outlet. The gas comes into contact with part of the coil 4 for a short time, thus completing the air-cooling heat dissipation of the low-flow medium.

[0037] The inlet structure 2 includes: a base 23, a swing frame 21 for arranging the air blowing devices 3, and a telescopic channel 22 arranged around the swing frame 21.

[0038] For example, the base 23 is arc-shaped. The side of the base 23 has a toothed shape, and a gear 211 is rotatably mounted on the swing frame 21. The gear 211 is driven by a motor. The motor drives the gear 211 to rotate, causing the swing frame 21 to slide along the base 23, thus adjusting the swing angle of the swing frame 21.

[0039] One end of the swing frame 21 is sway-connected to the inlet of the air-cooled cylinder 1, and the other end of the swing frame 21 is slidably mounted on the base 23. Cylinder seats 112 are installed at the upper and lower ends of the inlet 111 of the air-cooled cylinder 1, and one end of the swing frame 21 is hinged to the cylinder seat 112.

[0040] For example, the telescopic channel 22 is an aluminum foil telescopic tube. The shape of the telescopic channel 22 corresponds to the shape of the swing frame 21. The telescopic channel 22 is connected to the edge of the air-cooled cylinder 1 inlet. When the swing frame 21 swings, the telescopic channel 22 at the corresponding position extends or retracts, so that the telescopic channel 22 always surrounds the swing frame 21, allowing the gas blown out by the blower 3 to smoothly enter the air-cooled cylinder 1 and avoid leakage.

[0041] Figure 4 A schematic diagram of part of the coil structure in the first embodiment is shown. Combined with... Figures 1-4 As shown, the coil 4 includes: fins 44, a pipe rack 41 stacked vertically, a pipe 42 spirally laid horizontally on the pipe rack 41, and a secondary pipe 43 connecting the adjacent pipe 42.

[0042] The tube rack 41 connects the air-cooled cylinder 1 and the intermediate cylinder 5. In the horizontal direction, gaps exist between the pipes 42 to facilitate the installation of fins 44 and gas flow. In the vertical direction, gaps exist between the tube racks 41 to facilitate the installation of auxiliary pipes 43 and gas flow.

[0043] The secondary pipe 43 is used to connect pipes 42 on different pipe supports 41. Pipe 42 has fewer bends and welds, resulting in less impact on the inner wall of pipe 42 due to the spiral flow of the medium, and preventing leakage at the weld points. The secondary pipe 43 is distributed along the spiral curvature, and pipes 42 and 43 are connected by welding, allowing for smooth flow of the medium and reducing impact on the welded areas.

[0044] Fins 44 are wound around pipe 42 and secondary pipe 43. The heat of the medium is transferred to fins 44 through pipe 42 and secondary pipe 43, which increases the heat dissipation area of ​​the medium and can carry away more heat during gas flow.

[0045] Figure 5 It shows Figure 1 A schematic diagram of the exhaust mechanism. Figure 6 It shows Figure 5 A schematic diagram of the structure at point A in the middle. Figure 7 A partial top view of the hinge structure in the first embodiment is shown. Figure 8A schematic diagram showing the positions of 63a, 63b, 63c, and 63d in the first embodiment is shown. Figures 1-8 As shown, the exhaust mechanism 6 includes an inner ring frame 61 rotatably mounted on the intermediate cylinder 5 and an outer ring frame 62 rotatably mounted inside the air-cooling cylinder 1. An inner groove 511 is formed around the outer surface of the intermediate cylinder 5, and one end of the inner ring frame 61 is placed in the inner groove 511, rotating along the inner groove 511. An outer groove 113 is formed around the inner surface of the air-cooling cylinder 1, and the other end of the outer ring frame 62 is placed in the outer groove 113, rotating along the outer groove 113.

[0046] The other end of the inner ring frame 61 is slidably connected to one end of the outer ring frame 62. Ring pieces 611 are formed around the other end of the inner ring frame 61 and one end of the outer ring frame 62, respectively. The ring pieces 611 on the inner ring frame 61 and the ring pieces 611 on the outer ring frame 62 are inserted into each other in a staggered manner, and the ring pieces 611 slide against each other, so that the inner ring frame 61 and the outer ring frame 62 are slidably connected to each other.

[0047] The inner ring frame 61 rotates to open and close the inlet of the intermediate cylinder 5, and the outer ring frame 62 rotates to open and close the outlet of the air-cooled cylinder 1.

[0048] First support plates 612 are arranged at intervals around the inner side of the inner ring frame 61 and the outer side of the outer ring frame 62. The inner ring frame 61 is rotated at a certain angle, so that the first support plates 612 on the inner ring frame 61 cover the inlet of the intermediate cylinder 5, thus closing the inlet of the intermediate cylinder 5. The inner ring frame 61 is rotated back to its original position, so that the first support plates 612 on the inner ring frame 61 expose the inlet of the intermediate cylinder 5, thus opening the inlet of the intermediate cylinder 5.

[0049] The outer ring frame 62 rotates at a certain angle, causing the first plate 612 on the outer ring frame 62 to block the outlet of the air-cooled cylinder 1, thus closing the outlet of the air-cooled cylinder 1. The outer ring frame 62 rotates back to its original position, causing the first plate 612 on the outer ring frame 62 to expose the outlet of the air-cooled cylinder 1, thus opening the outlet of the air-cooled cylinder 1.

[0050] The exhaust mechanism 6 also includes a cover 63 that is slidably connected to the inner ring frame 61 and the outer ring frame 62; wherein the cover 63 opens and closes the inner ring frame 61 and the outer ring frame 62 to guide the gas flow in a preset direction.

[0051] The height of the inner ring frame 61 gradually decreases towards the outer ring frame 62. The height of the outer ring frame 62 gradually decreases towards the inner ring frame 61. For example, there are four sets of shielding cloths 63. The shielding cloths 63 are located on the upper and lower sides of the inner ring frame 61 and the upper and lower sides of the outer ring frame 62, respectively. Shielding cloths 63 are installed at positions 63a, 63b, 63c, and 63d in the attached diagram. The gas flow direction is changed by controlling the opening and closing of the shielding cloths 63 at each position.

[0052] The cover 63 is opened and closed by a drive mechanism 64. The drive mechanism 64 includes a crossbeam 641, a lead screw 642 rotatably disposed within the crossbeam 641, a slider 643 slidably disposed on the crossbeam 641, and a hinge 644 connected in sequence.

[0053] The lead screw 642 is threadedly connected to the slider 643. The lead screw 642 is driven to rotate by a motor, which in turn drives the slider 643 to move along the crossbeam 641. The slider 643 is connected to a cover 63, which covers and is connected to a hinge 644. The hinge 644 at its end is connected to the slider 643.

[0054] Slider 643 causes hinge 644 to extend, which unfolds the cover 63, closing the inner ring frame 61 and the outer ring frame 62. Slider 643 causes hinge 644 to retract, which folds the cover 63, opening the inner ring frame 61 and the outer ring frame 62.

[0055] Hinge 644 includes a second hinge plate 645 that is cross-hinged. The second hinge plates 645 on adjacent hinges 644 are hinged to each other. A slider 643 is connected to the cross-hinged position of the second hinge plate 645 on the end hinge 644.

[0056] The rotation of the second frame plate 645 enables the extension and retraction of the hinge 644. The second frame plate 645 supports the cover 63, improving the cover 63's resistance to gas impact.

[0057] The air cooler with adjustable airflow direction also includes a sensor 7 for detecting the temperature of the medium inside the coil 4. The sensor 7 is electrically connected to the inlet structure 2, the air blowing device 3, and the exhaust mechanism 6. For example, there are several sets of sensors 7 used to detect the temperature distribution inside the coil 4.

[0058] Second embodiment: The adjustment method for an air cooler with adjustable airflow direction includes the following steps: Start-up procedure: Medium flows into coil 4. Depending on the flow rate, switch between half-open and full-open modes. In half-open mode, medium flows into coil 4 located below exhaust mechanism 6; the air cooler with adjustable airflow can handle a smaller volume of medium. In full-open mode, medium flows into coil 4 located both above and below exhaust mechanism 6; the air cooler with adjustable airflow can handle a larger volume of medium.

[0059] The medium flows spirally into pipe 42 and then into the lower pipe 42 through the secondary pipe 43. The heat of the medium is transferred to pipe 42, secondary pipe 43, and fins 44. The blowing device 3 is activated to blow gas into the air-cooled cylinder 1. The gas contacts the coil 4 and rises spirally along the inside of the air-cooled cylinder 1, carrying away the heat of the medium.

[0060] The semi-open mode includes the following steps: the cover 63 closes part of the inner ring frame 61 and the outer ring frame 62, that is, the cover 63 at positions 63a and 63c is closed, thus dividing the air-cooled cylinder 1.

[0061] The angle between the inlet structure 2 and the air-cooled cylinder 1 is small. At this time, the outer ring frame 62 rotates to open the outlet of the air-cooled cylinder 1, and the cover 63 at position 63b closes, so that the gas blown out by the blowing device 3 flows spirally along the edge of the coil 4 and gradually rises, and the gas is discharged from the outlet of the air-cooled cylinder 1.

[0062] If the temperature of the inflow medium rises, the air cooling capacity of the air cooler with adjustable airflow direction needs to be increased. At this time, the outer ring frame 62 rotates in the opposite direction to reset and close the outlet of the air cooling cylinder 1, while the inner ring frame 61 rotates to open the outlet of the intermediate cylinder 5. At the same time, the shielding cloth 63 at position 63b opens and the shielding cloth 63 at position 63d closes, causing the gas blown out by the blowing device 3 to spiral flow and gradually rise. During the rising process, it moves closer to the outlet of the intermediate cylinder 5, allowing the gas to come into contact with more coils 4 and carry away more heat. The gas is then discharged from the outlet of the intermediate cylinder 5.

[0063] Adjustment steps: Sensor 7 detects the medium temperature, and the swing frame 21 moves along the base 23 to adjust the gas inflow angle. The medium temperature and the inflow angle are positively correlated.

[0064] If the temperature of the inflow medium continues to rise, the air cooling capacity of the air cooler with adjustable airflow direction needs to be further improved. The inlet structure 2 is oscillating to increase the angle between the inlet structure 2 and the air cooling cylinder 1, allowing the gas to extend into the coil 4 near the intermediate cylinder 5. At this time, the outer ring frame 62 rotates to open the outlet of the air cooling cylinder 1. Since the outlets of the air cooling cylinder 1 and the intermediate cylinder 5 open simultaneously, the gas blown out by the blowing device 3 flows spirally along the coil 4 and gradually rises. The gas is in complete contact with the coil 4, which can remove more heat. The gas is discharged from the outlets of the intermediate cylinder 5 and the air cooling cylinder 1 simultaneously.

[0065] The fully open mode includes the following steps: The cover 63 opens the inner ring frame 61 and the outer ring frame 62. Specifically, the cover 63 at positions 63a, 63b, 63c, and 63d is opened, connecting the air-cooled cylinder 1 internally. The inner ring frame 61 and the outer ring frame 62 rotate to close the outlet of the air-cooled cylinder 1 and the intermediate cylinder 5. The angle between the inlet structure 2 and the air-cooled cylinder 1 is small, causing the gas blown out by the blowing device 3 to spiral along the edge of the coil 4 and gradually rise, with the gas exiting from the top of the air-cooled cylinder 1.

[0066] Adjustment steps: Sensor 7 detects the medium temperature, and the swing frame 21 moves along the base 23 to adjust the gas inflow angle. The medium temperature and the inflow angle are positively correlated.

[0067] If the temperature of the inflow medium continues to rise, it is necessary to further improve the air cooling capacity of the air cooler with adjustable airflow direction. The inlet structure 2 is oscillating to increase the angle between the inlet structure 2 and the air cooling cylinder 1, so that the gas can extend into the coil 4 near the middle cylinder 5. The gas blown out by the blowing device 3 flows spirally along the coil 4 and gradually rises. The gas and the coil 4 are in complete contact, which can remove more heat. The gas is discharged from the top of the air cooling cylinder 1.

[0068] In full-open mode: If sensor 7 detects that the medium temperature exceeds the preset range, the air cooling capacity of the air cooler with adjustable airflow needs to be further increased. The outer ring frame 62 rotates to open the outlet of the air cooling cylinder 1, and external gas is drawn into the air cooling cylinder 1. This increases the amount of gas in the air cooling cylinder 1, and at the same time, it can also reduce the temperature inside the air cooling cylinder 1, increasing the heat carried away by the gas. The gas is discharged from the top of the air cooling cylinder 1.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
