Description

Technical Field

[0001] The present disclosure relates to the field of cooling technology, and in particular to an automatic adjustment heat exchange component, a cross-flow cooling tower and a heat exchange device. Background Art

[0002] Crossflow cooling towers have higher heat exchange efficiency than counterflow cooling towers, so crossflow cooling towers are the first choice for most refrigeration equipment. For example, the crossflow cooling tower disclosed in Chinese patent document No. CN 103759548 A, although heat exchange is performed with water through fillers on both sides, the fillers on both sides of the crossflow cooling tower are fixedly arranged in the cooling tower body, and for outdoor or open-air crossflow cooling towers, since they use natural wind, and the wind direction of natural wind is usually changeable, it is easy to cause the air inlet angles on both sides to change, which causes the air volume entering the fillers to become smaller to affect the heat exchange efficiency between the fillers on both sides and the water, and there is a problem of poor heat exchange efficiency. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide an automatically adjusting heat exchange component, a cross-flow cooling tower and a heat exchange device which can automatically adjust a porous filler plate according to the wind direction of natural wind to ensure that the porous filler plate has a higher air intake volume, thereby improving the heat exchange efficiency between the porous filler plate and water.

[0004] The purpose of this disclosure is achieved through the following technical solutions:

[0005] An automatic adjustment heat exchange component includes a porous filler plate, a connecting rod, a rotating drum, a fixing member and a limiting member.

[0006] The connecting rod is used to be horizontally arranged on the side wall of the cross-flow cooling tower body;

[0010] In one of the embodiments, the preset inclination angle is 20° to 40°.

[0011] In one embodiment, there are two fixing members, namely a first fixing member and a second fixing member. The first fixing member is located at the first end of the rotating drum, and the second fixing member is located at the second end of the rotating drum. A clamping cavity is formed between the first fixing member and the second fixing member. The porous filler plate is arranged in the clamping cavity and is connected to the first fixing member and the second fixing member respectively.

[0012] In one embodiment, the outer wall of the rotating drum is formed with a preset arc-shaped limit groove, and the outer wall of the connecting rod is formed with a threaded hole. The limit member passes through the preset arc-shaped limit groove and is screwed to the inner wall of the threaded hole, so that the rotating drum and the limit member can slide relative to each other in the preset arc-shaped limit groove.

[0013] In one embodiment, the number of the preset arc-shaped limiting grooves is at least plural, and the number of the limiting members matches the number of the preset arc-shaped limiting grooves; and / or,

[0014] The preset arc-shaped limiting groove is a preset arc-shaped limiting inclined groove; and / or,

[0016] In one embodiment, the porous filler plate is a honeycomb porous filler plate, which includes multiple layers of honeycomb pore layers, each layer of the honeycomb pore layer includes multiple guide flow holes, and a gap is formed between two guide flow holes in each adjacent layer.

[0017] A cross-flow cooling tower comprises the automatic adjustment heat exchange assembly described in any one of the above embodiments.

[0018] A heat exchange device comprises the cross-flow cooling tower described in any one of the above embodiments.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] Since the connecting rod is used to be horizontally arranged on the side wall of the cross-flow cooling tower body, the connecting rod and the side wall of the cross-flow cooling tower body are fixedly connected. Since the rotating drum is rotatably arranged on the connecting rod, and the rotating drum is connected to the porous filler plate through the fixing member, the rotating drum can rotate with the wind, thereby driving the porous filler plate connected to the rotating drum. Since the limiting member is arranged between the connecting rod and the rotating drum, the limiting member can limit the swinging of the porous filler plate in the heat exchange chamber of the cross-flow cooling tower body, so that the rotation of the porous filler plate will be automatically adjusted with the wind direction of the natural wind, so that the porous filler plate can well match the air intake of natural wind of various different wind directions, so as to ensure that the porous filler plate has a higher air intake, thereby improving the heat exchange efficiency between the porous filler plate and water, and is particularly suitable for outdoor or open-air cross-flow cooling towers.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] The present disclosure provides an automatically adjusting heat exchange component including a porous filler plate, and the heat exchange component also includes a connecting rod, a rotating drum, a fixing part and a limiting part. The connecting rod is used to be horizontally arranged on the side wall of the cross-flow cooling tower body; the rotating drum is rotatably arranged on the connecting rod, and the rotating drum is connected to the porous filler plate through the fixing part, the limiting part is arranged between the connecting rod and the rotating drum, and the limiting part is used to limit the swing of the porous filler plate in the heat exchange chamber of the cross-flow cooling tower body.

[0037] The above-mentioned automatic adjustment heat exchange assembly, because the connecting rod is used to be horizontally arranged on the side wall of the cross-flow cooling tower body, realizes the fixed connection between the connecting rod and the side wall of the cross-flow cooling tower body, because the rotating drum is rotatably arranged on the connecting rod, and the rotating drum is connected to the porous filler plate through the fixing member, so that the rotating drum can rotate with the wind, thereby driving the porous filler plate connected to the rotating drum, and because the limiting member is arranged between the connecting rod and the rotating drum, the limiting member can limit the porous filler plate from swinging in the heat exchange chamber of the cross-flow cooling tower body, so that the rotation of the porous filler plate will be automatically adjusted with the wind direction of the natural wind, so that the porous filler plate can well match the air intake of natural wind of various different wind directions, so as to ensure that the porous filler plate has a higher air intake, thereby improving the heat exchange efficiency between the porous filler plate and water, and is particularly suitable for outdoor or open-air cross-flow cooling towers. In addition, because the automatic adjustment heat exchange assembly adopts natural wind, the air intake energy consumption of the cross-flow cooling tower is effectively reduced to achieve energy-saving and environmental protection effects.

[0038] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0039] See also Figures 1 to 3 An automatic adjustment heat exchange component 10 of one embodiment includes a porous filler plate 100, and the heat exchange component also includes a connecting rod 200, a rotating drum 300, a fixing member 400 and a limiting member 500. The connecting rod 200 is used to be horizontally arranged on the side wall of the cross-flow cooling tower body 20; the rotating drum 300 is rotatably arranged on the connecting rod 200, and the rotating drum 300 is connected to the porous filler plate 100 through the fixing member 400, and the limiting member 500 is arranged between the connecting rod 200 and the rotating drum 300, and the limiting member 500 is used to limit the porous filler plate 100 from swinging in the heat exchange chamber 21 of the cross-flow cooling tower body 20.

[0040] It can be understood that since the connecting rod 200 is used to be horizontally arranged on the side wall of the cross-flow cooling tower body 20, the connecting rod 200 is fixedly connected to the side wall of the cross-flow cooling tower body 20. Since the rotating drum 300 is rotatably arranged on the connecting rod 200, and the rotating drum 300 is connected to the porous filler plate 100 through the fixing member 400, the rotating drum 300 can rotate with the wind, thereby driving the porous filler plate 100 connected to the rotating drum 300. Since the limiting member 500 is arranged on the connecting rod 200, the rotating drum 300 can rotate with the wind, thereby driving the porous filler plate 100 connected to the rotating drum 300. Between the rotating drum 300, the limiting member 500 can limit the swing of the porous filler plate 100 in the heat exchange chamber 21 of the cross-flow cooling tower body 20, so that the rotation of the porous filler plate 100 will be automatically adjusted with the wind direction of the natural wind, so that the porous filler plate 100 can well match the air intake of natural winds of various different wind directions, so as to ensure that the porous filler plate 100 has a high air intake, thereby improving the heat exchange efficiency between the porous filler plate 100 and water, and is particularly suitable for outdoor or open-air cross-flow cooling towers 1. In addition, since the automatic adjustment heat exchange component 10 uses natural wind, the air intake energy consumption of the cross-flow cooling tower 1 is effectively reduced to achieve energy-saving and environmental protection effects.

[0041] In one of the embodiments, the porous filler plate 100 swings at an angle of 0° to 90° in the heat exchange chamber 21 of the cross-flow cooling tower body 20, effectively preventing the porous filler plate 100 from colliding with the cross-flow cooling tower body 20 due to a large swing in the heat exchange chamber 21 of the cross-flow cooling tower body 20, thereby avoiding damage to the porous filler plate 100.

[0042] In a preferred embodiment, the porous filler plate 100 swings in the heat exchange chamber 21 of the cross-flow cooling tower body 20 at an angle of 0° to 50°.

[0043] It can be understood that if the rotation of the drum 300 is used alone to realize the automatic wind adjustment setting of the porous filler plate 100, then for some natural winds with relatively large wind directions, the drum 300 will rotate to a large extent, which will not only generate greater noise, but also increase the wear between the drum 300, the connecting rod 200 and the limit member 500, thereby affecting the service life of the automatic adjustment heat exchange component 10.

[0044] Therefore, if Figure 7As shown, in one embodiment, the fixing member 400 is connected to the connecting rod 200 to form a preset tilt angle, so that the porous filler plate 100 can be tilted on the connecting rod 200. When encountering natural wind with a large wind direction angle, the drum 300 will follow the natural wind and make a small adjustment at the original tilt angle, effectively reducing the rotation distance of the drum 300. In this way, while reducing the generation of noise, the service life of the automatic adjustment heat exchange component 10 is also improved. Specifically, the preset tilt angle can be reasonably set according to the natural wind at the geographical location of the cross-flow cooling tower 1.

[0045] For example, in the southern Guangdong region, the user can set the preset inclination angle of the fixing member 400 and the connecting rod 200 according to the wind direction of the geographical location of Guangdong, so as to ensure that the porous filler plate 100 can be automatically adjusted with the wind direction of the natural wind, reduce the noise, and improve the service life of the automatic adjustment heat exchange assembly 10. Further, in one embodiment, the preset inclination angle is 20° to 40°.

[0046] In a preferred embodiment, the preset inclination angle is 27° to 30°, and the porous filler plate 100 swings in the heat exchange cavity 21 of the cross-flow cooling tower body 20 at an angle of 20° to 40°.

[0047] It can be understood that in actual applications, since most of the natural wind in Guangdong Province is southeast wind, if the preset inclination angle is greater than 30°, the adjustment range of the subsequent drum 300 will be small, and it will not be able to adapt to the natural wind in Guangdong Province well. If the preset inclination angle is less than 27°, the adjustment range of the drum 300 will be large, resulting in louder noise and greater wear of the drum 300. Therefore, by setting the preset inclination angle of the connecting rod 200 and the drum 300 to 27°~30°, it is ensured that the inclination angle of the connecting rod 200 and the drum 300 is more suitable. On the premise of better adapting to the natural wind in Guangdong Province, it also minimizes the generation of noise and reduces the wear of the drum 300, thereby improving the automatic adjustment of the heat exchange component 10.

[0048] It can also be understood that if the porous filler plate 100 swings at an angle lower than 20° or higher than 40° in the heat exchange chamber 21 of the cross-flow cooling tower body 20, it cannot adapt well to the southeast wind in Guangdong Province. Therefore, in the present disclosure, by setting the porous filler plate 100 to swing at an angle of 20° to 40° in the heat exchange chamber 21 of the cross-flow cooling tower body 20, the inclined porous filler plate 100 can be adjusted left and right at a small amplitude at the original inclination angle to follow the southeast wind in Guangdong Province. In this way, while effectively reducing the distance of the left and right swing of the drum 300, it also effectively reduces the generation of noise, and also improves the service life of the automatic adjustment heat exchange component 10, so as to better adapt to the automatic adjustment of natural winds of various wind directions in Guangdong Province.

[0049] like Figure 6 and Figure 7 As shown, in one embodiment, the number of the fixing members 400 is two, namely a first fixing member 410 and a second fixing member 420. The first fixing member 410 is located at the first end of the rotating drum 300, and the second fixing member 420 is located at the second end of the rotating drum 300. A clamping cavity 430 is formed between the first fixing member 410 and the second fixing member 420. The porous filler plate 100 is arranged in the clamping cavity 430 and is respectively connected to the first fixing member 410 and the second fixing member 420 to achieve clamping and fixing of the porous filler plate 100.

[0050] It should be noted that, since the porous filling plate 100 is arranged in the clamping cavity 430, the first fixing member 410 and the second fixing member 420 are respectively located on both sides of the porous filling plate 100, which effectively avoids the problem of the first fixing member 410 and the second fixing member 420 affecting the water intake of the porous filling plate 100 due to being located above the porous filling plate 100. In this way, while ensuring the stability of the connection between the porous filling plate 100 and the connecting rod 200, it is also guaranteed that the porous filling plate 100 has a higher water intake.

[0051] It is understandable that in actual applications, two limiters 500 are generally used to limit and fix the porous filler plate 100 on the left and right sides, but the additional limiters 500 on the left and right sides will affect the circulation of wind, especially when the limiters 500 are on the air inlet side, the additional limiters 500 will not only block the entry of wind but also interfere with the change of wind direction, resulting in the interference of this part of wind can not fully enter the porous filler plate 100 to affect the heat exchange efficiency between the porous filler plate 100 and water. In order to improve the above technical problems, some scholars believe that simply adding a limiter 500 on the leeward side can better ensure the air intake of the porous filler plate 100, but the additional limiter 500 on the leeward side will interfere with the air outlet inside the cross-flow cooling tower body 20.

[0052] Therefore, in one embodiment, the outer wall of the rotating drum 300 is formed with a preset arc-shaped limit groove 310, so that the rotating drum 300 can slide well in the preset arc-shaped limit groove 310; the outer wall of the connecting rod 200 is formed with a threaded hole 210, and the limit member 500 passes through the preset arc-shaped limit groove 310 and is screwed to the inner wall of the threaded hole 210, so as to realize the fixed connection between the limit member 500 and the connecting rod 200, while the rotating drum 300 and the limit member 500 are movably arranged. When natural wind blows toward the porous filler plate 100, the rotating drum 300 connected to the porous filler plate 100 will be affected by the wind resistance in the preset arc-shaped limit groove 31 0 slides, thereby enabling the rotating drum 300 and the limiting member 500 to slide relative to each other in the preset arc-shaped limiting groove 310, thereby enabling the porous packing plate 100 to swing in the heat exchange chamber 21 of the cross-flow cooling tower body 20. In this way, on the premise that the porous packing plate 100 swings in the heat exchange chamber 21 of the cross-flow cooling tower body 20, it is also ensured that there is no interference between the wind inlet side and the leeward side of the porous packing plate 100, thereby better ensuring the air inlet and air outlet of the porous packing plate 100, and better ensuring the comprehensive and rapid heat exchange efficiency between the water in the porous packing plate 100 and the natural wind in the porous packing plate 100.

[0053] In one embodiment, the number of the preset arc-shaped limit grooves 310 is at least multiple, and the number of the limit members 500 is adapted to the number of the preset arc-shaped limit grooves 310. By increasing the number of the preset arc-shaped limit grooves 310 and the limit members 500, the flexibility of rotation of the rotating drum 300 and the limit members 500 is improved to better adapt to the automatic adjustment of natural winds in different wind directions.

[0054] In one of the embodiments, the preset arc-shaped limit groove 310 is a preset arc-shaped limit inclined groove, which enables the rotating drum 300 to slide better with the natural wind, that is, to ensure that the rotating drum 300 is not prone to jamming during rotation, and at the same time enables the rotating drum 300 to automatically adjust to the natural wind with a smaller wind inlet angle better, so as to ensure that the porous filler plate 100 can well match the automatic adjustment of natural winds of various wind directions.

[0055] In one embodiment, the limiting member 500 is a pin or a bolt to achieve a fixed connection between the limiting member 500 and the connecting member.

[0056] It can be understood that, although the positioning member 500 is arranged in the preset arc-shaped positioning groove 310, it can effectively reduce the interference with the wind direction and the impact on the air intake, but it will interfere with the water intake of the porous filler plate 100. Therefore, in the present disclosure, the positioning member 500 is arranged within the positive projection area of ​​the connecting rod 200, which effectively avoids the problem that the positioning member 500 is arranged on the side of the connecting rod 200 and blocks the water intake of the porous filler plate 100.

[0057] Specifically, in one of the embodiments, the limit member 500 is arranged at the bottom of the positive projection area of ​​the connecting rod 200, so that when the porous filler plate 100 is subjected to resistance from the wind direction, the rotating drum 300 will slowly slide from the bottom of the limit member 500 to a higher position. When the resistance from the wind direction disappears, the rotating drum 300 returns to its original position under the action of the gravity of the porous filler plate 100. In this way, the resetting operation of the rotating drum 300 can be restored without using an elastic member, while also ensuring that the porous filler plate 100 has a high water inlet.

[0058] In one of the embodiments, the rotation trajectory of the rotating drum 300 and the connecting rod 200 is an eccentric circular trajectory, so that the rotating drum 300 can swing left and right flexibly and stably under the influence of different wind directions, while also better reducing the noise and wear between the rotating drum 300, the connecting rod 200 and the limiter 500, thereby increasing the service life of the automatic adjustment heat exchange assembly 10.

[0059] like Figure 5 As shown, in one embodiment, the connecting rod 200 is cylindrical, and the rotating drum 300 is sleeved on the connecting rod 200 to ensure that the rotating drum 300 can rotate on the connecting rod 200 more flexibly. When in use, when the rotating drum 300 is not swinging, the top of the rotating drum 300 and the connecting rod 200 form the highest tangent point 600, the limiting member 500 is located at the bottom of the connecting rod 200, and the limiting member 500 is located on the diameter of the highest tangent point 600 with the connecting rod 200 as the center, so that the tangent point 600 and the limiting member 500 are respectively located at the two ends of the diameter with the connecting rod 200 as the center. In this way, while ensuring that the rotating drum 300 can rotate flexibly and reliably on the connecting rod 200 and the limiting member 500, it is also beneficial for the rotating drum 300 to be quickly reset after the wind resistance disappears, and it also effectively reduces the generation of noise and improves the service life of the automatic adjustment heat exchange component 10.

[0060] like Figure 5 As shown, it can be understood that since the rotation trajectory of the rotating drum 300 and the connecting rod 200 is an eccentric circular trajectory, that is, there is a certain gap 120 between the bottom of the rotating drum 300 and the bottom of the connecting rod 200, it is easy to cause the rotating drum 300 to get stuck at the corner of the rotation. Therefore, in one embodiment, the diameter of the stopper 500 gradually decreases from the end close to the connecting rod 200 to the end away from the connecting rod 200, so that the diameter of the end away from the connecting rod 200 is smaller, so as to effectively avoid the problem of the rotating drum 300 getting stuck at the corner of the rotation, and ensure that the rotating drum 300 can quickly return to its original position when the wind resistance disappears, that is, quickly reset, so as to better adapt to the adjustment of the next natural wind.

[0061] In one embodiment, the eccentricity between the rotating drum 300 and the connecting rod 200 is 10 mm to 30 mm.

[0062] In one embodiment, the limit member 500 includes a limit block 510 and a locking rod 520 connected to each other. The limit block 510 protrudes from one side of the locking rod 520. A threaded portion 521 is formed at one end of the locking rod 520 away from the limit block 510. The threaded portion 521 includes a plurality of thread rings. When in use, the threaded portion 521 is screwed onto the inner circumferential wall of the threaded hole 210, and the number of thread rings exposed from the threaded hole 210 is 1 / 5 to 2.

[0063] It can be understood that since the threaded ring exposed in the threaded hole 210 and the limit block 510 can form a sliding groove 522, so that the rotating drum 300 can slide reliably and smoothly in the sliding groove 522, if the threaded ring exposed in the threaded hole 210 is less than 1 / 5, the firmness of the connection between the limit member 500 and the connecting rod 200 cannot be achieved, that is, the rotating drum 300 is prone to fall off when it swings. If the threaded ring exposed in the threaded hole 210 is greater than 2, the threaded portion 521 is distributed longer on the locking rod 520, resulting in a narrower width of the sliding groove 522, and it is impossible to provide the rotating drum 300 with more rotation margin at the corners, so that the rotating drum 300 is prone to get stuck at the corners when rotating. Therefore, in the present disclosure, by controlling the number of threaded circles exposed in the threaded hole 210 to 1 / 5 to 2, the distribution of the threaded portion 521 on the locking rod 520 is ensured to be more appropriate. In this way, while ensuring that more rotation margin can be provided for the rotating drum 300 at the corner, the firmness of the connection between the limit member 500 and the connecting rod 200 is achieved, and the problem of the rotating drum 300 easily falling off after swinging for a long time is effectively avoided; it also effectively reduces the generation of noise and improves the service life of the automatic adjustment heat exchange component 10.

[0064] Furthermore, since the diameter of the locking rod 520 gradually decreases from the end close to the connecting rod 200 to the end away from the connecting rod 200, the depth of the sliding groove 522 close to the limit block 510 is deeper, which reduces the contact area between the preset arc limit groove 310 and the locking rod 520. Combined with the use of 1 / 5 to 2 of the number of thread rings exposed in the threaded hole 210, the rotating drum 300 at the corner is less likely to get stuck, and the noise generation is better reduced. It also reduces the problem of the rotating drum 300 at the corner causing the limit member to loosen when rotating.

[0065] In one embodiment, the locking rod 520 is provided with a long threaded portion, and the threaded portion extends to at least 1 / 2 of the connecting rod 200 and does not penetrate the other side of the connecting rod 200, so as to increase the contact area between the locking rod 520 and the connecting rod 200, thereby effectively reducing the probability of the locking rod 520 being loosened when the rotating drum 300 rotates. Furthermore, the threaded portion is a double thread.

[0066] In one of the embodiments, a preset micro gap is formed between the locking rod 520 and the preset arc-shaped limit groove 310. In this way, while ensuring that the locking rod 520 can provide a better guiding effect for the rotating drum 300, the probability of the rotating drum 300 contacting the locking rod 520 during the rotation process is also reduced, so as to minimize the probability of the locking rod 520 loosening when the rotating drum 300 rotates.

[0067] In a preferred embodiment, the number of threaded circles exposed in the threaded hole 210 is 1, and in particular, the length of the sliding groove 522 accounts for 1 / 2 to 2 / 3 of the length of the locking rod 520. The diameter of the locking rod 520 gradually decreases from the end close to the connecting rod 200 to the end away from the connecting rod 200, so as to ensure that the rotating drum 300 can flexibly rotate on the limit member 500 and the connecting member 200, while also reducing the probability of the limit member 500 loosening due to long-term rotation of the rotating drum 300.

[0068] In one of the embodiments, the distance between the limit member 500 and the preset arc-shaped limit groove 310 adjacent to the spray pipe 24 is smaller than the distance between the limit member 500 and the preset arc-shaped limit groove 310 away from the spray pipe 24, so that the distance between the limit member 500 and the air inlet surface of the porous filler plate 100 is longer than the distance between the limit member 500 and the leeward surface of the porous filler plate 100, so that the natural wind from the outside can more easily drive the rotating drum 300 to rotate. On the premise of improving the adaptability of the automatic adjustment heat exchange component 10 to natural winds of various wind directions, the noise generation and wear problems of the rotating drum 300 when rotating are also reduced.

[0069] like Figure 5As shown, it is worth mentioning that since the limiting member 500 is located at the bottom of the connecting rod 200, and the distance between the limiting member 500 and one end of the preset arc-shaped limiting groove 310 adjacent to the wind inlet surface of the porous filler plate 100 is greater than the distance between the limiting member 500 and one end of the preset arc-shaped limiting groove 310 adjacent to the leeward side of the porous filler plate 100, the limiting member 500 is not located at the center position of the preset arc-shaped limiting groove 310, and the force arm from the limiting member 500 to the wind inlet surface of the porous filler plate 100 adjacent to the preset arc-shaped limiting groove 310 is greater than the force arm from the limiting member 500 to the leeward side of the porous filler plate 100 adjacent to the preset arc-shaped limiting groove 310, so that the rotating drum 300 is more labor-saving when rotating with the wind, thereby reducing the limiting member 500, the rotating drum 300 and the connecting rod 200. The wear and noise problems between the connecting rods 200 are effectively avoided, and the wear and noise problems between the limiter 500, the rotating drum 300 and the connecting rod 200 are caused by long-term rotational friction on the side walls of the preset arc-shaped limit groove 310, thereby improving the service life of the automatic adjustment heat exchange component 10. In addition, the rotating drum 300 is located below the spray pipe 24, so that when the rotating drum 300 rotates with the wind, the preset arc-shaped limit groove 310 of the rotating drum 300 can be located below the spray pipe 24 with a higher moisture content, so that the moisture can have a better lubricating effect on the side walls of the preset arc-shaped limit groove 310, further reducing the wear and noise problems between the limiter 500, the rotating drum 300 and the connecting rod 200.

[0070] Furthermore, especially with the position-limiting member 500 being located at the bottom of the connecting rod 200, on the one hand, the position-limiting member 500 is effectively avoided to be disposed on the side of the connecting rod 200 and thereby block the water inflow of the porous filler plate 100, thereby ensuring that the porous filler plate 100 has a high water inflow; on the other hand, it is also convenient for the drum 300 to quickly reset after the wind disappears, so as to better prepare for the next natural wind adjustment, thereby reducing the deviation problem of the automatic adjustment to the next natural wind.

[0071] In one embodiment, the rotating drum 300, the limiting member 500 and the connecting rod 200 are made of stainless steel. Since stainless steel has high mechanical strength and good wear resistance, it is ensured that the rotating drum 300, the limiting member 500 and the connecting rod 200 can maintain normal operation after long-term use.

[0072] In one of the embodiments, the outer walls of the rotating drum 300, the limiting member 500 and the connecting rod 200 are all covered with a ceramic coating. Since the ceramic coating has good wear resistance and thermal conductivity, the added ceramic coating can effectively reduce the heat generated when the rotating drum 300, the limiting member 500 and the connecting rod 200 rotate. At the same time, in combination with an environment with a high moisture content, the ceramic coating can achieve better lubrication, effectively reducing the wear and noise problems between the limiting member 500, the rotating drum 300 and the connecting rod 200.

[0073] In one embodiment, the ceramic coating is a porous ceramic coating. Since the porous ceramic coating has a pore structure, the water absorption of the ceramic coating is increased to a certain extent, thereby providing a storage space for water, thereby better ensuring the lubrication effect between the rotating drum 300, the limit member 500 and the connecting rod 200.

[0074] In one embodiment, the porosity of the porous ceramic coating is 55% to 75%, so as to ensure that the porous ceramic coating has good wear resistance and good mechanical properties while having high water absorption.

[0075] In one embodiment, the thickness of the porous ceramic coating is 2 mm to 10 mm, so as to ensure that a more suitable porous ceramic coating can satisfy the requirements of the porous ceramic coating in terms of higher water absorption, better wear resistance and better mechanical properties.

[0076] like Figures 1 to 3 As shown, in one embodiment, the porous filler plate 100 is a honeycomb porous filler plate 100, and the honeycomb porous filler plate 100 includes a plurality of honeycomb pore layers 110, each of which includes a plurality of guide flow holes 111, and a gap 120 is formed between two guide flow holes 111 of each adjacent layer, so that water in the guide flow holes 111 of the upper layer can flow to the guide flow holes 111 of the lower layer, which not only realizes the multi-layer filtering effect on water, but also realizes a more comprehensive cooling of water to meet the cooling water requirements of refrigeration equipment.

[0077] In one embodiment, the porous packing plate 100 is a plastic porous packing plate 100. It is understood that since the plastic porous packing plate 100 is lighter than the metal porous packing plate 100, it can effectively reduce the force on the drum 300, so as to ensure that the drum 300 can rotate with the wind better, so as to better adapt to the adjustment of natural winds of various wind directions, and ensure that the drum 300 has high flexibility during the rotation process, that is, it is not easy to get stuck, and the noise and wear problems are reduced. Specifically, the plastic porous packing plate 100 is a PVC blue dumb porous packing plate 100.

[0078] In one embodiment, the porosity of the porous filler plate 100 is 80% to 98% to ensure that the porous filler plate 100 has a higher water storage capacity, thereby improving the utilization rate of the porous filler plate 100 in a single heat exchange.

[0079] It is understandable that in order to improve the utilization rate of a single heat exchange of the porous filler plate 100, a higher porosity is generally used. However, although the higher porosity increases its water storage capacity, it will cause the force on the drum 300 to be relatively large, so that the drum 300 cannot be ensured to rotate well with the wind. Therefore, in the present disclosure, by setting the porosity of the porous filler plate 100 to 80% to 90%, under the premise of ensuring that the drum 300 can rotate well with the wind to improve the adaptability of the automatic heat exchange component 10 to natural winds of multiple wind directions, the porous filler plate 100 is also ensured to have a higher utilization rate of a single heat exchange, and serious noise and wear problems of the drum 300, the connecting rod 200 and the stopper 500 are avoided.

[0080] In one embodiment, the guide flow hole 111 is tilted on the porous filler plate 100 so that the guide flow hole 111 forms a certain angle with the natural wind outside to better adapt to the natural wind in Guangdong Province. Specifically, the tilt angle between the guide flow hole 111 and the porous filler plate 100 is 2° to 15°.

[0081] It can be understood that since the temperature of the water near the spray pipe 24 of the porous packing plate 100 is the highest, the heat exchange energy of the porous packing plate 100 near the spray pipe 24 is higher. Therefore, in one embodiment, the size of the gap 120 of the guide flow hole 111 of each layer is set to gradually decrease from the end near the spray pipe 24 to the end away from the spray pipe 24, so as to achieve faster cooling of the water of the porous packing plate 100 near the spray pipe 24, and effectively avoid the problem that heat is accumulated at one end of the porous packing plate 100 near the spray pipe 24, which causes the porous packing plate 100 to be easily deformed due to excessive heat.

[0082] In one embodiment, the guiding flow hole 111 is a regular pentagon.

[0083] like Figure 8 and Fig.10 As shown, in one embodiment, the porous filler plate 100 includes a plurality of corrugated plates, which are arranged and connected in sequence along the horizontal direction, so that each two adjacent corrugated plates form a multi-layer honeycomb pore layer 110 in the horizontal direction and form a connected gap 120 in the vertical direction, so as to achieve the self-flow effect of the porous filler plate 100, and also realize the circulation of wind and water in each layer of the honeycomb pore layer 110, thereby ensuring that the water and wind in the porous filler plate 100 can achieve faster heat exchange.

[0084] like Fig.10As shown, in one of the embodiments, the width of the gap 120 gradually increases from the air inlet surface close to the porous packing plate 100 to the leeward surface of the porous packing plate 100, and in particular, the size of the gap 120 of the guide flow hole 111 of each layer gradually decreases from the end close to the spray pipe 24 to the end away from the spray pipe 24, so that the width of the gap 120 in the length direction of the porous packing plate 100 gradually decreases from the top to the bottom of the porous packing plate 100, and gradually increases from the air inlet surface to the leeward surface in the thickness direction of the porous packing plate 100. In this way, better natural wind energy from the outside can enter from the air inlet surface, that is, the wind gathering and disturbance of the air volume on the air inlet surface is achieved, and the gathered air volume can be better circulated to the interior and leeward surface of the porous packing plate 100 under the action of the exhaust fan 25. In this way, on the premise of increasing the air inlet volume of the porous packing plate 100, the heat exchange efficiency between water and wind in the porous packing plate 100 is also accelerated to achieve rapid cooling of the water.

[0085] like Fig. 9 As shown, in one embodiment, each layer of the honeycomb pore layer 110 is curved, such as an S shape, so that on the one hand, the water storage capacity of the porous filler plate 100 is increased, and on the other hand, the specific surface area of ​​the honeycomb pore layer 110 is increased to ensure high water storage capacity and high heat exchange area of ​​the porous filler plate 100, so as to achieve rapid cooling of water.

[0086] In one embodiment, an expansion portion is formed at the open end of the honeycomb porous layer 110 adjacent to the spray pipe 24 to ensure that the opening of the honeycomb porous layer 110 of the spray pipe 24 can more comprehensively receive the water sprayed from the spray pipe 24 to achieve more comprehensive cooling of the water.

[0087] In one of the embodiments, the width of the porous packing plate 100 gradually decreases from the end close to the spray pipe 24 to the end away from the spray pipe 24, so that the porous packing plate 100 is conical, so as to ensure that the porous packing plate 100 has a faster flow rate, thereby achieving rapid and comprehensive cooling of the water, and the weight of the conical porous packing plate 100 is lighter than that of the square porous packing plate 100, so as to ensure that the drum 300 can rotate flexibly with the wind, so as to better adapt to the adjustment of natural wind in various wind directions, and effectively reduce the noise and wear problems during the rotation of the drum 300.

[0088] like Figure 6 and Figure 7 As shown, the present disclosure further provides a cross-flow cooling tower 1, comprising the automatic adjustment heat exchange assembly 10 described in any of the above embodiments.

[0089] It can be understood that the cross-flow cooling tower 1 includes a cross-flow cooling tower body 20, a heat exchange chamber 21 is formed in the cross-flow cooling tower body 20, a connecting rod 200 of the automatic heat exchange assembly 10 is arranged on a side wall of the heat exchange chamber 21, and the porous filler plate 100 of the automatic heat exchange assembly 10 is connected to the heat exchange chamber 21, and an inner water inlet pipe 22 and a water outlet pipe 23 are also arranged in the cross-flow cooling tower body 20, and the inner water inlet pipe 22 and the water outlet pipe 23 are respectively arranged on both sides of the bottom of the heat exchange chamber 21, and the inner water inlet pipe 22 extends to the top of the porous filler plate 100 and is connected to the spray pipe 24. When the inner water inlet pipe 22 is connected to the external water pump, the water pump can transport the water in the inner water inlet pipe 22 to the spray pipe 24, and then the water is discharged through the spray pipe 24. The shower pipe 24 sprays water on the porous filler plate 100, and then the water flows from the top to the bottom of the porous filler plate 100, thereby completing the heat exchange between water and wind in the porous filler plate 100. When the wind direction of the external natural wind changes, the rotating drum 300 can rotate with the wind, thereby driving the porous filler plate 100 connected to the rotating drum 300 to swing, so that the rotation of the porous filler plate 100 will automatically adjust with the wind direction of the natural wind, so that the porous filler plate 100 can well match the air intake of natural winds of various different wind directions, so as to ensure that the porous filler plate 100 has a higher air intake, thereby improving the heat exchange efficiency between the porous filler plate 100 and water, and is particularly suitable for outdoor or open-air cross-flow cooling towers 1.

[0090] It can also be understood that since the inner water inlet pipe 22 and the water outlet pipe 23 are respectively arranged on both sides of the bottom of the heat exchange chamber 21, water can flow from the bottom of the heat exchange chamber 21 to the top of the heat exchange chamber 21, thereby realizing the initial heat exchange between the water in the inner water inlet pipe 22 and the heat exchange chamber 21, and then the water circulates back from the top of the heat exchange chamber 21 to the bottom of the heat exchange chamber 21. At the same time, with the use of the exhaust fan 25, the heat exchange efficiency between the water in the heat exchange chamber 21 and the wind is greatly improved, so as to achieve a more comprehensive and better cooling effect on the water.

[0091] like Figure 7 As shown, in one embodiment, the inner water inlet pipe 22 is formed with a right-angle bend to ensure that the inner water inlet pipe 22 has the longest distribution length in the heat exchange chamber 21, thereby achieving better cooling of the water in the inner water inlet pipe 22. Specifically, the inner water inlet pipe 22 includes a horizontal water inlet pipe and a vertical water inlet pipe, and the horizontal water inlet pipe is connected to the spray pipe 24 through the vertical water inlet pipe.

[0092] In one of the embodiments, the inner water inlet pipe 22 located in the heat exchange chamber 21 is a white PVC pipe, and the side wall of the inner water inlet pipe 22 exposed in the heat exchange chamber 21 is provided with a heat-insulating and anti-corrosion coating. Since the white PVC pipe has good heat dissipation, the water in the inner water inlet pipe 22 located in the heat exchange chamber 21 can achieve good heat exchange with the heat exchange chamber 21, thereby achieving better cooling of the water in the inner water inlet pipe 22, and the side wall of the inner water inlet pipe 22 exposed in the heat exchange chamber 21 is provided with a heat-insulating and anti-corrosion coating to reduce the heat absorption of the water in the exposed inner water inlet pipe 22 to affect the cooling effect of the water, and to increase the service life of the inner water inlet pipe 22 exposed in the heat exchange chamber 21.

[0093] In one embodiment, the number of automatically adjusting heat exchange components 10 is two, one of which is arranged on the left side of the heat exchange chamber 21, namely, the left automatic adjusting heat exchange component 26; the other automatically adjusting heat exchange component 10 is arranged on the right side of the heat exchange chamber 21, namely, the right automatic adjusting heat exchange component 27, so as to achieve faster and more comprehensive cooling of the water in the internal water inlet pipe 22.

[0094] like Figure 7 As shown, in one of the embodiments, the inclination angle between the left-side automatic heat exchange component 26 and the heat exchange chamber 21 is mirror-symmetrical with the inclination angle between the right-side automatic heat exchange component 27 and the heat exchange chamber 21, so that the left-side automatic heat exchange component 26 and the right-side automatic heat exchange component 27 can better adapt to the natural wind intake requirements of various wind directions.

[0095] In one embodiment, the right-angle bend is located at the center of the heat exchange chamber 21 to ensure that the water drawn by the vertical water inlet pipe can be evenly sprayed to the porous filler plates 100 on both sides to achieve uniform and rapid cooling of the inner water inlet pipe 22 .

[0096] like Figure 7 As shown, in one embodiment, a plurality of nozzles 241 are provided on the spray pipe 24, and the nozzles 241 are equidistantly distributed along the length direction of the spray pipe 24, so that the plurality of nozzles 241 can quickly and evenly spray the water in the spray pipe 24 onto the porous filler plate 100. On the premise of realizing the rapid spraying of the water in the spray pipe 24, the porous filler plate 100 can also be effectively prevented from being damaged and deformed due to the high spraying water pressure of individual nozzles 241.

[0097] like Figure 7As shown, in one embodiment, the cross-flow cooling tower 1 also includes a water guide cover 28, which is arranged on the spray pipe 24, so that the added water guide cover 28 can effectively avoid the problem of water splashing during the spraying process of the multiple nozzles 241 in the spray pipe 24, so as to ensure that the water in the spray pipe 24 can be sprayed more comprehensively onto the porous filler plate 100, thereby achieving comprehensive and rapid cooling of the water in the spray pipe 24.

[0098] In one of the embodiments, the nozzles 241 are distributed in a matrix above the porous packing plate 100 to ensure that the multiple nozzles 241 distributed in the matrix can evenly spray the water in the spray pipe 24 onto the top of the porous packing plate 100, thereby effectively avoiding the problem that the top of the porous packing plate 100 is easily deformed due to the high spray water pressure of some nozzles 241, especially when the spray flow rate of each nozzle 241 is 1.0 liters / minute to 3.2 liters / minute.

[0099] like Figure 7 As shown, in one embodiment, the exhaust fan 25 is located at the center of the top of the heat exchange chamber 21, so that the added exhaust fan 25 can extract the heat in the heat exchange chamber 21 more quickly to ensure that the heat exchange chamber 21 has a better heat exchange efficiency.

[0100] It can be understood that, since the exhaust fan 25 is located at the center of the top of the heat exchange chamber 21, the exhaust fan 25 will generate a large negative pressure when it is pumped, which will also drive the drum 300 to rotate, resulting in a large deviation between the guide flow holes 111 of the porous filler plate 100 and the air inlet angle of the external natural wind, making it difficult for the external natural wind to enter the guide flow holes 111 and affect the heat exchange efficiency between water and wind in the porous filler plate 100. Therefore, in the present disclosure, the rotation speed of the exhaust fan 25 is controlled to be 800 rpm to 1200 rpm to ensure that the exhaust fan 25 can just completely extract the air in the heat exchange chamber 21 when it is working, and will not drive the drum 300 to rotate, so as to effectively reduce the interference of the exhaust fan 25, which causes the guide flow holes 111 of the porous filler plate 100 to be unable to adapt to the air inlet angle of the external natural wind and affect the heat exchange efficiency between water and wind in the porous filler plate 100.

[0101] In one embodiment, the spraying flow rate of the nozzle 241 is 1.0 liter / minute to 3.2 liter / minute, and the water inlet flow rate of the inner water inlet pipe 22 is 80m 3 / h~100m 3 / h, the water output of the outlet pipe 23 is 60m 3 / h~80m 3 / h, to ensure that the porous filler plate 100 has a high cooling flow rate and cooling effect, that is, to achieve a better cooling effect of 23℃ to 25℃ for the normal temperature of 37℃, and also to ensure that the weight of the porous filler plate 100 when filled with water is relatively suitable, so as to ensure that the drum 300 can rotate more flexibly with the wind, so as to better adapt to the adjustment of natural winds of various wind directions, and effectively reduce the noise and wear during the rotation of the drum 300. Specifically, the noise does not exceed 45 decibels.

[0102] The present disclosure also provides a heat exchange device, including the cross-flow cooling tower 1 described in any of the above embodiments. It can be understood that the heat exchange device can be a central air conditioner, and the water inlet of the cooling water of the central air conditioner is connected to the water outlet of the cross-flow cooling tower 1, so that the cooling water of the cross-flow cooling tower 1 can enter the central air conditioner to achieve a better cooling effect on the refrigerant in the central air conditioner, so as to achieve better energy saving and environmental protection of the heat exchange device, and also ensure the good cooling and cooling of the central air conditioner for a long time, thereby ensuring the continuous normal operation of the central air conditioner.

[0103] Compared with the prior art, the present invention has at least the following advantages:

[0104] Since the connecting rod 200 is used to be horizontally arranged on the side wall of the cross-flow cooling tower body 20, the connecting rod 200 is fixedly connected to the side wall of the cross-flow cooling tower body 20. Since the rotating drum 300 is rotatably arranged on the connecting rod 200, and the rotating drum 300 is connected to the porous filler plate 100 through the fixing member 400, the rotating drum 300 can rotate with the wind, thereby driving the porous filler plate 100 connected to the rotating drum 300. In addition, since the limiting member 500 is arranged between the connecting rod 200 and the porous filler plate 100, the rotating drum 300 can rotate with the wind. Between the rotating drums 300, the limiting member 500 can limit the porous filler plate 100 from swinging in the heat exchange chamber 21 of the cross-flow cooling tower body 20, so that the rotation of the porous filler plate 100 will be automatically adjusted with the wind direction of the natural wind, so that the porous filler plate 100 can well match the air intake of natural winds of various different wind directions, so as to ensure that the porous filler plate 100 has a high air intake, thereby improving the heat exchange efficiency between the porous filler plate 100 and water, and is particularly suitable for outdoor or open-air cross-flow cooling towers 1. In addition, since the automatic adjustment heat exchange component 10 uses natural wind, the air intake energy consumption of the cross-flow cooling tower 1 is effectively reduced to achieve energy-saving and environmental protection effects.

[0105] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
