Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of cooling technology, in particular to an automatic adjustment heat exchange assembly and cross flow cooling tower. BACKGROUND

[0002] The cross flow cooling tower has higher heat exchange efficiency than the counter flow cooling tower, so the cross flow cooling tower is currently the first choice for most refrigeration equipment. The cross flow cooling tower disclosed in Chinese patent document No. CN 103759548 A exchanges heat with water through the fillers on both sides, but the fillers on both sides of the above cross flow cooling tower are fixedly arranged in the cooling tower body. For outdoor or open-air type cross flow cooling towers, since they use natural wind, the direction of the natural wind is usually variable, which easily causes the air inlet angle of both sides to change, thus causing the air volume entering the filler to become smaller to affect the heat exchange efficiency of the fillers on both sides and the water, and there is a problem of poor heat exchange efficiency. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present disclosure is to overcome the deficiencies in the prior art, and to provide an automatic adjustment heat exchange assembly and cross flow cooling tower, in which the porous filler plate is automatically adjusted according to the direction of the natural wind, so as to ensure that the porous filler plate has a higher air inlet volume, thereby improving the heat exchange efficiency of the porous filler plate and the water.

[0004] The purpose of the present disclosure is achieved by the following technical solutions:

[0005] An automatic adjustment heat exchange assembly, comprising a porous filler plate, the heat exchange assembly further comprising a connecting rod, a rotating drum, a fixing member and a limiting member,

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

[0007] The rotating drum is rotatably arranged on the connecting rod, and the rotating drum is connected with the porous filler plate through the fixing member. The limiting member is arranged between the connecting rod and the rotating drum, and the limiting member is used to limit the swing of the porous filler plate in the heat exchange cavity of the cross flow cooling tower body.

[0008] In one embodiment, the swing angle of the porous filler plate in the heat exchange cavity of the cross flow cooling tower body is 0°-90°.

[0009] In one embodiment, the fixing member and the connecting rod are connected to form a preset inclination angle.

[0010] In one embodiment, the preset inclination angle is 20°-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, a preset arc-shaped limit groove is formed on the outer peripheral wall of the rotating drum, and a threaded hole is formed on the outer peripheral wall of the connecting rod. 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.

[0014] In one embodiment, the preset arc-shaped limiting groove is a preset arc-shaped limiting inclined groove; and / or,

[0015] The limiting member is a pin or a bolt.

[0016] In one embodiment, the porous filler plate is a honeycomb porous filler plate, which includes multiple honeycomb hole layers, each honeycomb hole layer includes multiple flow holes, and a gap is formed between two 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] Compared with the prior art, the present disclosure has at least the following advantages:

[0019] Since the connecting rod is used to be horizontally arranged on the side wall of the cross-flow cooling tower body, a fixed connection between the connecting rod and the side wall of the cross-flow cooling tower body is achieved. 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 automatically adjust with the wind direction of the natural wind, so that the porous filler plate can well match the air intake of natural winds of various wind directions, 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.

The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] For better understanding of the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0032] Please refer to FIG. 1 to FIG. 4 Figure 3 The automatic adjustment heat exchange assembly 10 of an embodiment comprises a porous filler plate 100, and further comprises a connecting rod 200, a rotating drum 300, a fixing member 400 and a limiting member 500. The connecting rod 200 is arranged horizontally on the side wall of the cross-flow cooling tower body 20. The rotating drum 300 is arranged rotatably on the connecting rod 200, and the rotating drum 300 is connected with the porous filler plate 100 through the fixing member 400. Please refer to FIG. 3 and FIG. 4 Figure 4 The limiting member 500 is arranged between the connecting rod 200 and the rotating drum 300, and is used for limiting the swing of the porous filler plate 100 in the heat exchange cavity 21 of the cross-flow cooling tower body 20.

[0033] It can be understood that, since the connecting rod 200 is used to be arranged on the side wall of the cross flow cooling tower body 20, the connecting rod 200 is fixedly connected with the side wall of the cross flow cooling tower body 20, the rotating drum 300 is arranged on the connecting rod 200, and the rotating drum 300 is connected with the porous filler plate 100 through the fixing member 400, so that the rotating drum 300 can rotate with the wind, thereby driving the porous filler plate 100 connected with the rotating drum 300, and since the limiting member 500 is arranged between the connecting rod 200 and the rotating drum 300, the limiting member 500 can limit the swing of the porous filler plate 100 in the heat exchange cavity 21 of the cross flow cooling tower body 20, so that the rotation of the porous filler plate 100 can be automatically adjusted according to the wind direction of the natural wind, so that the porous filler plate 100 can well match the air inlet amount of the natural wind with different wind directions, so as to ensure that the porous filler plate 100 has a high air inlet amount, thereby improving the heat exchange efficiency of the porous filler plate 100 and the water, and the cross flow cooling tower 1 is especially suitable for outdoor or open-air type.

[0034] In one embodiment, the swing angle of the porous filler plate 100 in the heat exchange cavity 21 of the cross flow cooling tower body 20 is 0°-90°, which effectively avoids the collision between the porous filler plate 100 and the cross flow cooling tower body 20 due to the large swing of the porous filler plate 100 in the heat exchange cavity 21 of the cross flow cooling tower body 20, thereby avoiding the damage of the porous filler plate 100.

[0035] In a more preferred embodiment, the swing angle of the porous filler plate 100 in the heat exchange cavity 21 of the cross flow cooling tower body 20 is 0°-50°.

[0036] It can be understood that, if the rotating drum 300 is used alone to realize the automatic adjustment of the porous filler plate 100, the rotating drum 300 will rotate greatly to produce noise for some natural wind with a relatively large wind direction angle. Therefore, in one embodiment, the fixing member 400 and the connecting rod 200 are connected to form a preset inclination angle, so that the porous filler plate 100 can be arranged on the connecting rod 200 at an inclination angle, and when encountering natural wind with a large wind direction angle, the rotating drum 300 can automatically adjust at the original inclination angle, effectively reducing the rotation distance of the rotating drum 300, thereby reducing the noise and improving the service life of the automatic adjustment heat exchange assembly 10. Specifically, the preset inclination angle can be reasonably set according to the natural wind at the geographical position of the cross flow cooling tower 1.

[0037] 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 geographical location of Guangdong, so as to ensure that the porous filler plate 100 can automatically adjust the wind direction of the natural wind, and also reduce the rotation distance of the rotating drum 300, thereby reducing the noise and improving the service life of the automatic adjustment heat exchange assembly 10. Further, in one embodiment, the preset inclination angle is 20°-40°.

[0038] In a more preferred embodiment, the preset inclination angle is 27°-30°, especially in combination with the use of the porous filler plate 100 in the heat exchange cavity 21 of the cross-flow cooling tower body 20 with a swing angle of 20°-40°, to better adapt to the southeast wind in Guangdong Province.

[0039] In one embodiment, the number of the fixing member 400 is two, which are the first fixing member 410 and the 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 connected with the first fixing member 410 and the second fixing member 420, thereby achieving clamping and fixing of the porous filler plate 100.

[0040] It should be noted that, since the porous filler 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 filler plate 100, thereby effectively avoiding the problem that the first fixing member 410 and the second fixing member 420 affect the water inflow of the porous filler plate 100 due to being located above the porous filler plate 100. In this way, the stability of the connection between the porous filler plate 100 and the connecting rod 200 is ensured, and the porous filler plate 100 also has a high water inflow.

[0041] 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. However, adding limiters 500 on the left and right sides will block the flow of wind. In particular, when the limiters 500 are on the air inlet side, the added limiters 500 will not only block the entry of wind but also interfere with the change of wind direction, resulting in this part of the wind being unable to fully enter the porous filler plate 100, thereby affecting the heat exchange efficiency between the porous filler plate 100 and the water. In order to improve the above-mentioned technical problems, some scholars believe that adding a limiter 500 on the leeward side can better ensure the air intake of the porous filler plate 100. However, the additional limiter 500 on the leeward side will also interfere with the air outlet inside the crossflow cooling tower body 20. Therefore, in one embodiment, the outer wall of the rotating drum 300 is formed with a preset arc-shaped limiting groove 310, and the outer wall of the connecting rod 200 is formed with a threaded hole 210. The limiting member 500 passes through the preset arc-shaped limiting groove 310 and is screwed to the inner wall of the threaded hole 210, so as to realize the fixed connection between the limiting member 500 and the connecting rod 200, while the rotating drum 300 and the limiting member 500 are movably connected. When natural wind blows toward the porous filler plate 100, the rotating drum 300 connected to the porous filler plate 100 is subjected to wind resistance in the preset arc-shaped limiting groove 310. 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 filler plate 100 to swing in the heat exchange cavity 21 of the cross-flow cooling tower body 20. In this way, while enabling the porous filler plate 100 to swing in the heat exchange cavity 21 of the cross-flow cooling tower body 20, it is also ensured that the wind inlet side and the leeward side of the porous filler plate 100 are not interfered with, thereby better ensuring the air inlet and air outlet of the porous filler plate 100, and better ensuring the heat exchange efficiency between water and natural wind.

[0042] 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 preset arc-shaped limit grooves 310 and the limit members 500, the flexibility of the rotation of the rotating drum 300 and the limit members 500 is improved, so as to better adapt to the automatic adjustment of natural winds in different wind directions.

[0043] In one embodiment, 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 better automatically adjust to the natural wind with a smaller wind inlet angle, so as to ensure that the porous filler plate 100 can well match the automatic adjustment of natural winds of various wind directions.

[0044] In one of the embodiments, the limiting member 500 is a pin or a bolt to achieve the fixed connection of the limiting member 500 and the connecting member.

[0045] As shown in Figure 2 and Figure 3 In one of the embodiments, the porous filler plate 100 is a honeycomb porous filler plate 100, which includes multiple layers of honeycomb hole layers 110, each layer of the honeycomb hole layer includes multiple flow-through holes 111, and a gap 120 is formed between two flow-through holes 111 of each adjacent layer, so that the water in the flow-through hole 111 of the upper layer can flow into the flow-through hole 111 of the lower layer, not only achieving the multi-layer filtering effect on the water, but also achieving the comprehensive cooling of the water to meet the cooling water requirements of the refrigeration equipment.

[0046] As shown in Figure 5 and Figure 6 The disclosure also provides a cross-flow cooling tower 1, which includes the automatic adjustment heat exchange assembly 10 of any of the above embodiments.

[0047] It can be understood that the cross-flow cooling tower 1 includes a cross-flow cooling tower body 20, a heat exchange cavity 21 is formed in the cross-flow cooling tower body 20, the connecting rod 200 of the automatic adjustment heat exchange assembly 10 is arranged on one side wall of the heat exchange cavity 21, and the porous filler plate 100 of the automatic adjustment heat exchange assembly 10 is communicated with the heat exchange cavity 21. The cross-flow cooling tower body 20 is also provided with an inner water inlet pipe 22 and a water outlet pipe 23, which are respectively arranged on both sides of the bottom of the heat exchange cavity 21, and the inner water inlet pipe 22 extends above the porous filler plate 100 and is communicated with a spray pipe 24. When the inner water inlet pipe 22 is communicated with an 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 sprayed on the porous filler plate 100 through the spray pipe 24. Then the water will flow from the top to the bottom of the porous filler plate 100, so as to complete the heat exchange between the water and the wind in the porous filler plate 100. Please refer to Figure 6 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. 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 inlet amount of the natural wind of various different wind directions, so as to ensure that the porous filler plate 100 has a high air inlet amount, thereby improving the heat exchange efficiency between the porous filler plate 100 and the water. It is especially suitable for outdoor or open-air cross-flow cooling towers 1.

[0048] Compared with the prior art, the disclosure has at least the following advantages:

[0049] Since the connecting rod 200 is used to be arranged on the side wall of the cross flow cooling tower body 20, the fixed connection between the connecting rod 200 and the side wall of the cross flow cooling tower body 20 is realized, since the rotating drum 300 is arranged on the connecting rod 200, and the rotating drum 300 is connected with the porous filler plate 100 through the fixing piece 400, the rotating drum 300 can rotate with the wind, so as to drive the porous filler plate 100 connected with the rotating drum 300, and since the limiting piece 500 is arranged between the connecting rod 200 and the rotating drum 300, the limiting piece 500 can limit the swing of the porous filler plate 100 in the heat exchange cavity 21 of the cross flow cooling tower body 20, so that the rotation of the porous filler plate 100 can be automatically adjusted with the wind direction of the natural wind, so that the porous filler plate 100 can well match the air inlet amount of the natural wind with various wind directions, so as to ensure that the porous filler plate 100 has a high air inlet amount, thereby improving the heat exchange efficiency of the porous filler plate 100 and the water, and the cross flow cooling tower 1 is especially suitable for outdoor or open-air type.

[0050] The above-mentioned embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it cannot be understood as the limitation of the disclosed patent scope. It should be noted that for ordinary skilled in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
