Description

Technical Field

[0001] This invention relates to the field of air coolers, specifically to a compact vertical induced draft finned air cooler. Background Technology

[0002] Air coolers use air as a cooling medium, transferring the heat of a high-temperature fluid to the flowing air through a heat exchanger, thereby reducing the fluid's temperature.

[0003] CN220250785U discloses an air cooler with a heat recovery structure. A mounting base is installed on the back of the air collector shroud, and a semi-spherical shell is rotatably installed inside the mounting base. The semi-spherical shell can rotate horizontally or tilt at the same time, and can always pass through the air collector shroud and communicate with the exhaust port of the air cooler body during the movement. Therefore, it is convenient to adjust the arrangement position of the heat recovery pipe, and further facilitates the docking between the air cooler and the heat recovery equipment.

[0004] However, some air coolers are small in size and generate less heat. The cost of transferring this heat to a heat recovery device for recycling may exceed the value of the heat itself, making it uneconomical and resulting in ineffective heat utilization. Furthermore, in cold weather, the absorption of heat from high-temperature fluids by heat exchangers can cause the fluid temperature to drop too low, leading to condensation or freezing, which also affects performance. Therefore, this invention provides a compact vertical induced draft plate-fin air cooler. Summary of the Invention

[0011] Preferably, a pair of vertical openings in the air guide box are sliding openings, facing opposite directions and matching the rotation direction of the adjustment device; a first air outlet and a second air outlet are respectively opened on the front and rear sides of the air guide box; a pair of first limiting beads are fixedly connected to the side wall of the second air outlet; the position of the first limiting beads corresponds to the orientation of the sliding opening; the air guide hole penetrates through the air guide box.

[0012] Preferably, the heat dissipation component includes a heat dissipation plate, a sliding plate, and a heat absorption bag; the heat dissipation plate is fixedly connected to the air guide box body on one side with a second air outlet; a third air outlet is opened in the middle of the heat dissipation plate, and the third air outlet is slidably adjusted by the sliding plate; a support frame for mounting the heat absorption bag is provided on the outer periphery of the third air outlet.

[0013] Preferably, the outer wall of the adjusting semi-ring is provided with a first rack for meshing with the drive device; the windshield is hollow in the middle and has openings on the front and rear sides along the axial direction of the air inlet cover; the windshield matches the interior of the air guide box and has a ventilation hole matching the air guide hole in the middle of the side wall away from the air inlet cover.

[0014] Preferably, the adjusting device further includes a pair of switching plates, a wind deflector, and a pair of rotating plates; the pair of switching plates are slidably connected to the pair of wind deflector housings respectively; the pair of rotating plates are fixedly connected to the upper and lower parts of the pair of switching plates respectively; the wind deflector is fixedly connected to the upper side of the wind deflector housing of the corresponding downward-facing air guide box.

[0015] Preferably, one of the windshield shells corresponds to the air guide box with the opening facing downwards, and one of the rotating plates is fixedly connected to the upper part of the switching plate inside the windshield shell and fits against the top side of the inner wall of the windshield shell; the other windshield shell corresponds to the air guide box with the opening facing upwards, and the other rotating plate is fixedly connected to the lower part of the switching plate inside the windshield shell and fits against the bottom side of the inner wall of the windshield shell.

[0016] Preferably, two pairs of second limiting beads are fixedly connected to the inner sidewalls of a pair of wind deflectors.

[0019] Compared with the prior art, the beneficial effects of the present invention are: by setting up an air guide box device and an adjustment device, the hot air generated by the air cooler body is reused, thereby ensuring a high-quality cooling effect on the fluid.

[0020] In cold weather, by rotating the windshield out of the air guide box, the air duct is connected to the air inlet shroud, allowing heat from the air duct to be transferred to the air inlet shroud, increasing the temperature inside. During heat exchange with the fluid, this reduces the release of fluid temperature, preventing condensation or freezing. The windshield has a ventilation hole on only one side; when rotated into the air guide box, it can also deliver the airflow from the air duct to the outside.

[0021] In hot weather, auxiliary cooling can be implemented to ensure the release of heat from the fluid. By pulling the switching plate to the second limit bead, the airflow in the air duct 13 is guided to pass through the second air outlet and the heat dissipation bag for cooling before being blown onto the outer shell of the air cooler body, thereby further releasing the heat from the fluid.

[0022] After prolonged use, the drive unit can be used to rotate the drive shaft, rotating shaft, and brush to clean the filter surface. This ensures sufficient airflow into the air inlet shroud, allowing the air cooler to provide a stable cooling effect for the fluid. Attached Figure Description

Detailed Implementation

[0038] Example 1:

[0039] Please see Figures 1-14 This invention provides a technical solution: a compact vertical induced draft plate-fin air cooler, such as... Figures 1-2 and Figure 14As shown, the system includes an air cooler body 11, an air inlet shroud 12, a pair of air ducts 13, and a fan. The air inlet shroud 12 is fixedly connected to the air inlet side of the air cooler body 11. The fan is located on the air inlet side of the air cooler body 11 and inside the air inlet shroud 12. The pair of air ducts 13 are located on both sides of the air cooler 11, with one end of each pair of air ducts 13 fixedly connected to the air outlet side of the air cooler body 11.

[0040] It also includes a pair of support parts 21, a pair of vertical openings with the openings facing opposite directions, an air guide box device 22, and an adjustment device 3.

[0041] A pair of air guide box devices 22 are fixedly connected to both sides of the outer wall of the air inlet shroud 12. A pair of support parts 21 are located on the upper and lower sides of the pair of air guide box devices 22 and are fixedly connected to the outer wall of the air inlet shroud 12. The support parts 21 are arc-shaped and match the outer wall of the air inlet shroud 12. An air guide hole 221 is opened in the middle of the air guide box device 22. The air guide hole 221 penetrates the air inlet shroud 12. The other ends of a pair of air guide pipes 13 are fixedly connected to the outside of the pair of air guide box devices 22 and communicate with the air guide hole 221.

[0042] The adjusting device 3 is rotatably connected to the outer wall of the support portion 21 on the lower side of the air guide box device 22. When both ends of the adjusting device 3 are rotated to the outside of the air guide box device 22, the air guide pipe 13 communicates with the air inlet hood 12, and is used to deliver air into the air inlet hood 12. When the end of the adjusting device 3 is rotated to the inside of the air guide box device 22, the air guide pipe 13 is not communicated with the air inlet hood 12, and is used to change the direction of the air output from the air guide pipe 13.

[0043] The lower side of the support part 21 is engaged with a drive device 5.

[0044] like Figures 2-6As shown, the air guide box device 22 includes an air guide box body 222 and a heat dissipation component 223. The inner wall of the air guide box body 222 is attached to the outer wall of the air inlet shroud 12 and is fixedly connected to the outer wall of the air inlet shroud 12. The heat dissipation component 223 is fixedly connected to the side of the air guide box body 222 near the air cooler body 11. The vertical opening of the air guide box body 222 is a sliding opening. One sliding opening faces downward and the other faces upward, to match the rotation direction of the adjusting device 3, so as to facilitate the adjusting device 3 to rotate into or out of the air guide box body 222. The air guide box body 222 with the sliding opening facing downward is on the left side of the air inlet shroud 12, and the air guide box body 222 with the sliding opening facing upward is on the right side of the air inlet shroud 12. A first air outlet 231 is opened on the side of the air guide box body 222 away from the air cooler body 11. The middle part of the side of the air guide box body 222 near the air cooler body 11 is hollowed out to serve as a second air outlet 232. A pair of first limiting beads 233 are fixedly connected to the side wall of the second air outlet 232. The position of the first limiting beads 233 corresponds to the orientation of the sliding opening. In the air guide box 222 with the sliding opening facing downward, the first limiting beads 233 are located on the lower side wall of the second air outlet 232. In the air guide box 222 with the sliding opening facing upward, the first limiting beads 233 are located on the upper side wall of the second air outlet 232. The air guide hole 221 penetrates through the air guide box 222.

[0045] The heat dissipation component 223 includes a heat dissipation plate 241, a sliding plate 242, and a heat absorption bag 243. The heat dissipation plate 241 is fixedly connected to one side of the air guide box 222 where the second air outlet 232 is located. A third air outlet 251 is located in the middle of the heat dissipation plate 241, and the width of the third air outlet 251 is smaller than that of the second air outlet 232. A sliding groove 252 is also located on the side of the heat dissipation plate 241 near the air guide box 222. The sliding groove 252 is larger than the third air outlet 251. The sliding plate 242 is slidably connected within the sliding groove 252 and is used to open or close the third air outlet 251. The sliding plate 242 protrudes upward from the top of the heat dissipation plate 241. A support frame extends from the outer periphery of the heat dissipation plate 241 toward the air cooler body 11. The heat absorption bag 243 is fitted onto the support frame and contains a cooling fluid, such as water or coolant.

[0046] like Figure 2 and Figures 7-11As shown, the adjusting device 3 includes an adjusting semi-ring 31, a pair of wind baffle shells 32, a pair of switching plates 33, a wind baffle 34, and a pair of rotating plates 35. The two ends of the adjusting semi-ring 31 are fixedly connected to the lower sides of the pair of wind baffle shells 32. The sides of the adjusting semi-ring 31 and the wind baffle shells 32 away from the air cooler body 11 are flush. The inner wall of the adjusting semi-ring 31 is rotatably connected to the outer wall of the support portion 21 on the lower side of the air inlet shroud 12. The outer wall of the adjusting semi-ring 31 is provided with a first rack, which meshes with the driving end of the driving device 5. The two ends of the first rack are designated as the beginning and end, with the beginning end close to the upward-facing air guide box 222. The driving device 5 is located at the beginning end of the rack. The wind baffle shell 32 has a hollow center and openings on both the front and rear sides along the axial direction of the air inlet shroud 12. The wind baffle shell 32 matches the interior of the air guide box 222, and a ventilation hole 321 is provided in the center of the side wall of the wind baffle shell 32 away from the air inlet shroud 12. The ventilation hole 321 and the air guide hole 221 are matched in diameter. When the windproof shell 32 is fully rotated into the air guide box 222, the ventilation hole 321 and the air guide hole 221 are connected.

[0047] A pair of switching plates 33 are slidably connected to a pair of windshield shells 32. A pair of rotating plates 35 are fixedly connected to the upper and lower parts of the pair of switching plates 33, respectively, and are used to drive the switching plates 33 to move.

[0048] One of the wind deflector shells 32 corresponds to the downward-opening air guide box 222. One rotating plate 35 is fixedly connected to the upper part of the switching plate 33 inside the wind deflector shell 32 and fits against the top side of the inner wall of the wind deflector shell 32. The other wind deflector shell 32 corresponds to the upward-opening air guide box 222. The other rotating plate 35 is fixedly connected to the lower part of the switching plate 33 inside the wind deflector shell 32 and fits against the bottom side of the inner wall of the wind deflector shell 32. Two pairs of second limiting beads 322 are also fixedly connected to the inner walls of the pair of wind deflector shells 32. The two pairs of second limiting beads 322 correspond to the pair of rotating plates 32 and are located on the top or bottom side of the inner walls of the pair of wind deflector shells 32, respectively. The second limiting beads 322 are located near the end of the wind deflector shell 32 away from the air cooler body 11. The wind deflector 34 is fixedly connected to the upper side of the wind deflector shell 32 of the corresponding downward-facing air guide box 222, and the inner wall of the wind deflector 34 matches the curvature of the outer wall of the support part 21.

[0049] The rotating plate 35 includes a snap-fit ​​plate 351, a first rotating plate 352, and a second rotating plate 353. The two ends of the first rotating plate 352 are rotatably connected to the snap-fit ​​plate 351 and the second rotating plate 353, respectively. The first rotating plate 352 and the second rotating plate 353 within the pair of rotating plates 35 are respectively attached to the top or bottom side of the inner wall of the windshield 32; both sides of the first rotating plate 352 and the second rotating plate 353 are slidably connected to the inner wall of the windshield 32.

[0050] The upper sides of the snap-fit ​​plate 351 and the first rotating plate 352, located on the top side of the windshield 32, are each provided with a first snap-fit ​​groove for engaging with the windshield plate 34, which has a first snap-fit ​​block. The lower sides of the snap-fit ​​plate 351 and the first rotating plate 352, located on the bottom side of the windshield 32, are provided with a second snap-fit ​​groove for engaging with the adjusting half-ring 31, which has a second snap-fit ​​block.

[0051] Working principle: In the initial state, the wind deflector 32 is completely located inside the air guide box 222, blocking the air passage to the air inlet shroud 12, so that the air volume in the air guide duct 13 cannot flow into the air inlet shroud 12. At the same time, a pair of snap-fit ​​plates 351 are snap-fitted and connected to the wind deflector 34 and the adjusting half ring 31 respectively.

[0052] When the air cooler body 11 is started, the airflow entering the air cooler body 11 cools the fluid and then flows out from the rear of the air cooler body 11. It then flows through the air duct 13, air duct 221, and ventilation hole 321 into the wind baffle 32, and finally exits from the front opening of the wind baffle 32. In extremely cold weather, to prevent excessive heat loss from the fluid, which could cause condensation or freezing, the position of the wind baffle 32 can be changed to direct the airflow from the air duct 13 into the air inlet shroud 12, thus warming the airflow within the air inlet shroud 12.

[0053] The specific operation is as follows: Define the air guide box 222 with the sliding opening facing downwards as the left air guide box 222, and the air guide box 222 with the sliding opening facing upwards as the right air guide box 222. The operator starts the drive device 5, which drives the adjusting half-ring 31, the windshield 32, the switching plate 33, and the rotating plate 35 to rotate together. The rotation direction is from the end of the first rack towards the beginning. Figure 9(As indicated by the arrow), the baffle shell 32 inside the left air guide box 222 rotates downward to the lower side of the corresponding air guide hole 221; the baffle shell 32 inside the right air guide box 222 rotates upward to the upper side of the corresponding air guide hole 221. At this time, the air guide pipe 13 communicates with the air guide hole 221 and the interior of the air inlet shroud 12, and the top or bottom of the pair of baffle shells 32 respectively block the sliding opening of the left air guide box 222 or the right air guide box 222. At the same time, the baffle plate 34 also rotates downward synchronously to the first air inlet 231 of the left air guide box 222 to close it; the adjusting half ring 31 near the right air guide box 222 moves upward to block the first air inlet 231; so that the air volume in the air guide pipe 13 can only flow into the air inlet shroud 12. Then the drive device 5 is turned off. Because the air volume in the air guide pipe 13 absorbs the heat of the fluid, its temperature is higher than the temperature of the gas in the air inlet shroud 12. Therefore, when the airflow in the duct 13 flows into the air inlet shroud 12, it mixes with the gas flowing into the air inlet shroud 12 from the outside, thereby increasing the overall temperature of the gas in the air inlet shroud 12. Then, when the heated mixed gas flows to the air cooler body 11, it will not reduce the heat of the fluid in the air cooler body 11 too much, ensuring that the fluid will not condense due to the low temperature when it flows out of the air cooler body 11.

[0054] The airflow entering the air inlet shroud 12 through the air duct 13 can also be adjusted to adapt to different external temperatures, thereby ensuring that the cooled fluid remains within a stable temperature range. When adjusting the semi-ring 31, the baffle 32, the switching plate 33, the rotating plate 35, and the rotation of the rotating plate 35, it is not necessary to completely rotate the baffle 32 inside the left air guide box 222 out; instead, rotate it out partially so that only a portion of the air guide hole 221 communicates with the interior of the air inlet shroud 12 (see...). Figure 11 The other part is connected to the ventilation hole 321; while the baffle plate 34 blocks the exposed first air outlet 231. Therefore, part of the air volume in the air duct 13 will flow into the air inlet shroud 12 through the air guide hole 221, and the other part will flow out from the front of the baffle shell 32 through the air guide hole 221 and the ventilation hole 321. Figure 11 The two arrows indicate the two directions of airflow. The right air guide box 222 is similar to the left air guide box 222, except that the adjusting half ring 31 blocks the first air outlet 231 exposed by the right air guide box 222.

[0055] In summer when the temperature is extremely high, in order to ensure that the fluid can be effectively cooled, the cooling component 223 can be used to cool the outside of the air cooler body 11 to assist in heat dissipation.

[0056] The specific operation is as follows: In the initial state, the operator disengages the snap-fit ​​plate 351 from the baffle plate 34, and then pulls the snap-fit ​​plate 351 away from the heat dissipation component 223. The snap-fit ​​plate 351 then drives the first rotating plate 352, the second rotating plate 353, and the switching plate 33 to move synchronously until the switching plate 33 abuts against the second limit bead 322. Then, the second rotating plate 353 is rotated upwards and snapped into the baffle plate 34. At this time, the switching plate 33 blocks the first air outlet 231. Then, the sliding plate 242 is moved so that the third air outlet 251 communicates with the second air outlet 232. The air volume in the air duct 13 will flow into the baffle shell 32 through the air guide hole 221 and the ventilation hole 321. Since the first air outlet 231 is blocked, the air volume will flow out of the baffle shell 32 through the second air outlet 232, the third air outlet 251, and the heat absorption bag 243, and blow towards the outer shell of the air cooler body 11. The width of the third air outlet 251 is smaller than that of the second air outlet 232, causing the airflow to accelerate and release heat. After the heat-absorbing bag 243 absorbs the heat, the temperature of the outflowing air is significantly reduced, while the air velocity is significantly increased, thus cooling the air cooler body 11. After use, the second rotating plate 352 is disengaged from the baffle plate 34, and then the locking plate 351 is pushed to move the first rotating plate 352, the second rotating plate 353, and the switching plate 33 toward the second air outlet 232 until the switching plate 33 abuts against the first limit bead 233. The operation of the rotating plate 35, which is locked to the adjusting half-ring 31, is the same as above, except that the locking plate 351 is locked to the adjusting half-ring 31.

[0057] Example 2

[0058] Based on Example 1, such as Figure 10 and Figures 12-13 As shown, a dust removal device 4 is also provided at the end of the air inlet hood 12. The dust removal device 4 includes a filter screen 41, a rotating shaft 42, a brush 43, a chain 44, and a drive shaft 45. The filter screen 41 is fixedly connected to the end of the air inlet hood 12. The rotating shaft 42 is rotatably connected to the middle of the filter screen 41. The brush 42 and the chain 44 are arranged sequentially on the rotating shaft 42 away from the filter screen 41. The brush 43 is fixedly connected to the outer wall of the rotating shaft 42 and is used to clean the dust on the filter screen 41. The drive shaft 45 is rotatably connected to the adjusting half-ring 31 and is located at the end of the first rack. The length of the first rack allows the windshield 32 to rotate out of the air guide box 222 and rotate further. The chain 44 is meshed with the rotating shaft 42 and the drive shaft 45 respectively. A second rack is fixedly connected to the outer wall of the drive shaft 45 between the chain 44 and the filter screen 41 for meshing with the drive device 5.

[0059] Working principle: After prolonged use, a lot of dust will accumulate on the surface of filter 41, affecting the air intake. The dust removal device 4 can also be used to remove dust from filter 41.

[0060] The specific operation is as follows: The operator starts the drive device 5, which drives the adjusting half-ring 31 and the drive shaft 45 to rotate until the adjusting half-ring 31 drives the windshield 32 to rotate out of the air guide box 222. The adjusting half-ring 31 continues to rotate until it reaches the end of the first rack. At this point, the adjusting half-ring 31 stops rotating, and the drive device 5 begins to engage with the drive shaft 45, driving the drive shaft 45 to rotate. The drive shaft 45 drives the chain 44, the rotating shaft 42, and the brush 43 to rotate. The brush 43 rotates along the center of the filter screen 41, beginning to remove dust from the surface of the filter screen 41. After dust removal is completed, the drive device 5 rotates in the opposite direction, re-engaging with the first rack and disengaging from the drive shaft 45. As the drive device 5 continues to rotate in the opposite direction, the windshield 32 returns to its initial state. Dust removal is completed.
