Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning cooling towers, in particular to a nozzle and a cooling tower. Background Art

[0002] Cooling towers are evaporative heat dissipation devices that dissipate excess heat generated in industrial and air conditioning applications to reduce water temperature. In central air conditioning systems, the heat conversion efficiency of cooling towers is crucial. One criterion for determining a cooling tower's cooling performance is whether the cooling water is evenly distributed from the tower's spray pan to the packing. The larger the surface area over which the cooling water spreads, the better the cooling tower's heat dissipation. Therefore, even distribution of cooling water across the spray pan is crucial. Existing cooling towers use nozzles to spray cooling water onto the spray pan, ensuring uniform water distribution.

[0003] Conventional nozzles include a housing with a water inlet on the side of the housing and a spiral baffle inside the inlet. A water dispersion unit is located within the housing. Cooling water flows through the inlet and through the baffle into the housing in a swirling pattern. Under the influence of gravity, it falls to the water dispersion unit, where it is dispersed and flows toward the spray pan. In this process, the cooling water's gravitational potential energy is converted into kinetic energy, which is superimposed on the impact force of the swirling water flow to increase the impact force on the water dispersion unit and improve the dispersion of the cooling water.

[0004] However, the vortex-shaped water inlet method easily causes the cooling water to collide with the water flow in the shell, which not only consumes the impact force of the water flow, causing the impact force of the water flow to be weakened, and failing to give the water dispersion part a greater impact force, but also consumes the kinetic energy converted from gravitational potential energy, resulting in a decrease in the falling speed of the cooling water, and at the same time reducing the impact force of the cooling water on the water dispersion part, affecting the dispersion effect of the cooling water, and reducing the uniformity of the water distribution of the sprinkler plate. Utility Model Content

[0005] In view of this, the present invention provides a nozzle and a cooling tower to solve the problem that the existing nozzle uses a vortex-shaped water inlet method, which easily causes the cooling water to collide with the water flow in the shell, resulting in a weakening of the water flow impact force, and is unable to give a greater impact force to the water dispersion part. It also consumes the kinetic energy converted from gravitational potential energy, resulting in a decrease in the falling speed of the cooling water, and at the same time reduces the impact force of the cooling water on the water dispersion part, affecting the cooling water dispersion effect and reducing the uniformity of the water distribution of the sprinkler.

[0006] In a first aspect, the present invention provides a nozzle, comprising:

[0007] The water inlet portion has a water inlet cavity inside, and at least two water inlet channels communicating with the water inlet cavity are provided on the side of the water inlet portion; the water inlet channels include:

[0008] a water inlet, provided on the outer wall of the water inlet portion;

[0009] a water outlet, provided on the inner wall of the water inlet;

[0010] The water outlets are arranged at intervals, and the water flows of the water outlets are independent of each other.

[0011] Beneficial Effects: By spacing out the water outlets and allowing the water flows from each outlet to flow independently of each other, and without any other structures in the water inlet chamber, compared to the related art of vortex trajectory water inlet, the water flows from each outlet enter the water inlet chamber along independent flow trajectories, which can avoid the occurrence of water flow collisions. As a result, the kinetic energy converted from the gravitational potential energy of the water in the water inlet will not be consumed due to water flow collisions, thereby reducing the energy consumption of the water flow in the water inlet, thereby achieving the technical effect of increasing the falling speed of the cooling water.

[0012] In an optional embodiment, on a cross section perpendicular to the axial direction of the water inlet, a line connecting the center of the water inlet and the center of the water outlet is arranged at an angle to the cross section;

[0014] Beneficial effect: The water is introduced into the nozzle along an oblique trajectory so that the water flows ejected from each water outlet flow independently of each other, thereby avoiding the occurrence of water flow collisions, reducing the energy consumption of the water flow in the water inlet, and thus achieving the technical effect of increasing the falling speed of the cooling water. At the same time, on a cross section perpendicular to the axial direction of the water inlet, a projection of the side of the water inlet of the water inlet channel is provided. When the projection of the water inlet channel is arranged perpendicular to the projection of the water inlet channel, by defining the line between the center of one water outlet and the center of the water inlet, and staggering the line between the center of another water outlet and the center of the water inlet, the water flows ejected from each water outlet can also flow independently of each other, thereby avoiding the occurrence of water flow collisions and consuming the energy of the water flow, thereby achieving the technical effect of increasing the falling speed of the cooling water.

[0018] In an optional embodiment, the nozzle includes:

[0019] The water separation part is connected to the lower part of the water collection part; the size of the end surface of the water separation part close to the water collection part and the size of the end surface of the water separation part away from the water collection part are both larger than the size of the end surface of the water collection part away from the water inlet part.

[0020] Beneficial effect: By setting up a water separation portion, and the end face size of the water separation portion close to the water gathering portion and the end face size of the water separation portion away from the water gathering portion are both larger than the end face size of the water gathering portion away from the water inlet portion, the cooling water falling through the water gathering portion will not contact the inner wall of the water separation portion, avoiding the energy consumption of the cooling water during the falling process, thereby reducing the loss of energy conversion between the gravitational potential energy and kinetic energy of the cooling water, thereby achieving the technical effect of increasing the descending flow rate of the cooling water.

[0021] In an optional embodiment, the nozzle includes:

[0022] The extension portion is connected to the lower side of the end surface of the water separation portion away from the water collection portion, or the extension portion is connected to the upper side of the end surface of the water separation portion close to the water collection portion;

[0023] The size of the end surface of the extension portion communicating with the water separation portion and the size of the end surface of the extension portion away from the water separation portion are not less than the size of the end surface of the water separation portion away from the water collection portion.

[0031] a housing, wherein a thread is provided on an inner side surface of the housing;

[0055] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0056] The following combination Figures 1 to 7 , describing the embodiments of the present utility model.

[0057] On the one hand, according to an embodiment of the present invention, a nozzle is provided, comprising:

[0058] The water inlet portion 1 has a water inlet cavity 101 therein, and at least two water inlet channels 102 are provided around the water inlet portion 1 and communicate with the water inlet cavity 101; each water inlet channel 102 includes:

[0059] The water inlet 1021 is provided on the outer wall of the water inlet portion 1;

[0060] A water outlet is provided on the inner wall of the water inlet portion 1;

[0061] The water outlets are arranged at intervals, and the water flows of the water outlets are independent of each other.

[0062] In the nozzle of this embodiment, the water outlets are spaced apart, and the water flows from each outlet flow independently of each other, and no other structure is provided in the water inlet chamber 101. Based on this, compared with the vortex trajectory water inlet in the related art, the water flows from each water outlet enter the water inlet chamber 101 along independent flow trajectories, which can avoid the occurrence of water flow collision. The kinetic energy converted from the gravitational potential energy of the water in the water inlet part 1 is not consumed by the water flow collision, thereby reducing the water flow energy consumption in the water inlet part 1, thereby achieving the technical effect of increasing the falling speed of the cooling water.

[0063] In addition, in this embodiment, along the cross section perpendicular to the axis of the water inlet 1, the line connecting the center of the water inlet 1021 and the center of the water outlet is arranged at an angle to the cross section, that is, the angle between the line connecting the center of the water inlet 1021 and the center of the water outlet and the cross section is not equal to 0 degrees and 180 degrees, that is, the line connecting the center of the water inlet 1021 and the center of the water outlet is an oblique line, and no other structure is set in the water inlet chamber 101, and the water outlets are arranged at intervals. Based on this, water is introduced along the oblique trajectory by the nozzle so that the water flows sprayed from each water outlet flow independently of each other, thereby avoiding the occurrence of water flow collisions, reducing the water flow energy consumption of the water inlet 1, and thus achieving the technical effect of increasing the falling speed of the cooling water.

[0064] Among them, Figure 5 As shown, the cross-section of the water inlet 1 is a regular hexagon, and the cross-section of each water inlet channel 102 is rectangular. The width of the water inlet 1021 and the water outlet of each water inlet channel 102 is 0.3mm-1.2mm, and the length of the water inlet 1021 and the water outlet is 5mm-20mm. Six water inlet channels 102 are provided on the side of the water inlet 1, and a water inlet channel 102 is provided on the side of each water inlet 1. Based on this, the angle α between the line connecting the center of the water inlet 1021 and the center of the water outlet and the cross-section is the angle between the line connecting the center of the water inlet 1021 and the center of the water outlet and the side of the water inlet 1. Of course, in other embodiments, the number of water inlet channels 102 and the cross-sectional shape of the water inlet 1 can also be adjusted according to the different designs of the nozzles.

[0065] Preferably, in this embodiment, the angle α between the line connecting the center of the water inlet 1021 and the center of the water outlet and the cross section is 25° to 60°. This allows water from adjacent water inlet channels 102 to enter the water inlet chamber 101 through the water outlets in separate trajectories. This allows the water ejected from each outlet to flow independently, preventing the water from counteracting and consuming water energy, thereby achieving the technical effect of increasing the falling speed of the cooling water.

[0066] In this embodiment, the angle between the line connecting the center of the water inlet 1021 and the center of the water outlet and the cross section is 45°.

[0067] Of course, in other embodiments, the angle between the line connecting the center of the water inlet 1021 and the center of the water outlet and the cross section can be adjusted according to the different designs of the nozzles, so that the water flows ejected from each water outlet are independent of each other.

[0068] Combine Figure 7 As shown, in other embodiments, a projection of the side of the water inlet 1 with a water inlet channel 102 may be provided on a cross section perpendicular to the axial direction of the water inlet 1, and the projection of the water inlet channel 102 may be arranged perpendicularly, so that the line between the center of one water outlet and the center of the water inlet 1 is staggered with the line between the center of the other water outlet and the center of the water inlet 1. Figure 7 The line connecting the center a of the upper water inlet and the center b of the upper water outlet is perpendicular to the top edge c of the cross section. Similarly, the line connecting the center d of the lower water inlet and the center e of the lower water outlet is perpendicular to the bottom edge f of the cross section. Furthermore, the line connecting the center b of the upper water outlet and the center g of the water inlet is staggered with the line connecting the center of any of the other five water inlets 1021 and the center g of the water inlet. Based on this, water can also flow independently from each other at each water outlet.

[0069] In addition, combined Figure 4 As shown, in this embodiment, the nozzle includes:

[0070] The water collecting part 2 is connected to the lower part of the water inlet 1. The size of the end surface 201 connecting the water collecting part and the water inlet is larger than the size of the end surface 202 away from the water inlet, that is, the cross section of the water collecting part 2 is trumpet-shaped.

[0071] Based on this, not only can the cooling water flowing out of the outlet of each water inlet channel 102 be drained and collected through the water collecting part 2, but the cooling water can also be squeezed through the end face 202 of the water collecting part away from the water inlet part, so as to achieve the technical effect of increasing the descending flow rate of the cooling water.

[0072] Of course, in other embodiments, the cross-section of the water collecting portion 2 may be adjusted according to different designs of the nozzle to achieve the technical effect of collecting cooling water.

[0073] In addition, combined Figure 2 and Figure 4 As shown, in this embodiment, the nozzle includes:

[0074] The water separation portion 3 is connected to the lower portion of the water collection portion 2. The end surface 301 of the water separation portion close to the water collection portion is connected to the end surface 202 of the water collection portion away from the water inlet portion. The size of the end surface 301 of the water separation portion close to the water collection portion and the size of the end surface 302 of the water separation portion away from the water collection portion are both larger than the size of the end surface 202 of the water collection portion away from the water inlet portion. Based on this, the cooling water falling through the water collection portion 2 will not come into contact with the inner wall of the water separation portion 3, avoiding energy loss caused by the cooling water and the inner wall of the water separation portion 3 during the falling process, ensuring that the kinetic energy converted from the gravitational potential energy of the cooling water will not be lost, thereby achieving the technical effect of increasing the downward flow rate of the cooling water.

[0075] Among them, combined Figure 4 As shown, in this embodiment, the cross section of the water separation portion 3 is square. Of course, in other embodiments, the cross section of the water separation portion 3 can also be adjusted according to the design of the nozzle and actual use.

[0076] In addition, in this embodiment, the nozzle includes:

[0077] The extension portion is connected to the lower side of the end surface 302 of the water separation portion away from the water collection portion.

[0078] The size of the end face of the extension part connected to the water separation part 3 and the size of the end face of the extension part away from the water separation part 3 are both equal to the size of the end face 302 of the water separation part away from the water collection part. Figure 4 The vertical dimension shown is 5 mm to 10 mm. As a convertible embodiment, the specific extension dimension of the extension portion can be adjusted according to actual needs, and no excessive restrictions are made here.

[0079] Based on this, by setting an extension part, the height of the water inlet part 1 and the water collecting part 2 can be increased, that is, the falling height of the cooling water is increased, and the gravitational potential energy that can be converted into kinetic energy of the cooling water is further increased, thereby achieving the technical effect of increasing the falling speed of the cooling water.

[0080] Preferably, the extension portion is made integrally with the water separation portion 3 , that is, the extension portion is made as a part of the water separation portion 3 , so as to achieve the technical effect of improving the simplicity of making the extension portion.

[0081] Of course, in other embodiments, the extension part can be arranged between the water separation part 3 and the water collection part 2, and the size of the end face of the extension part connecting with the water separation part 3 and the size of the end face of the extension part away from the water separation part 3 are both larger than the size of the end face 302 of the water separation part away from the water collection part, which can also achieve the technical effect of reducing the energy consumption of cooling water and increasing the falling speed of cooling water.

[0082] In addition, in this embodiment, combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the nozzle includes:

[0083] The fixing portion 4 has a partial extension portion disposed therein. Since the extension portion is a part of the water separation portion 3, part of the water separation portion 3 is disposed within the water separation portion 3. The provision of the fixing portion 4 facilitates the installation and fixation of the water inlet portion 1, the water collecting portion 2, the water separation portion 3, and the extension portion, thereby achieving a technical effect of improving the stability of the positions of the water inlet portion 1, the water collecting portion 2, the water separation portion 3, and the extension portion.

[0084] Preferably, the fixing portion 4 is detachably connected to the water separation portion 3. Based on this, the positions of the water inlet portion 1, the water collecting portion 2, the water separation portion 3 and the extension portion relative to the fixing portion 4 can be adjusted, and the balance of the cooling water outlet level in the extension portion can be adjusted as needed, so as to adjust the level of the cooling water outlet level as needed.

[0085] Among them, the end face size of the fixed part 4 close to the water separation part 3 and the end face size of the fixed part 4 away from the water separation part 3 are not smaller than the end face 302 size of the water separation part away from the water collecting part, which can further avoid the cooling water from contacting the wall of the fixed part 4, causing energy loss, thereby achieving the technical effect of increasing the cooling water speed.

[0086] At the same time, through the detachable connection between the fixing part 4 and the water separation part 3, the extension part and the fixing part 4 can be assembled and disassembled as needed, so as to achieve the technical effect of improving the convenience of replacing the extension part and the fixing part 4.

[0087] In this embodiment, the outer side surface of the extension portion is provided with threads. In addition, the fixing portion 4 includes:

[0088] The housing 401 has a thread on its inner side;

[0089] The water distribution element 402 is disposed below the housing 401 and is used to evenly disperse the water flow.

[0090] By providing threads on the inner side of housing 401, housing 401 can be detachably connected to the threads provided on the outer side of the extension, improving the stability of the connection and simplifying assembly and disassembly. Furthermore, water diversion element 402 disperses cooling water falling from the extension, improving its dispersion and achieving a more even cooling water distribution.

[0091] Specifically, the water diversion element 402 includes:

[0092] The first water diversion element 4021 is fixed below the housing 401;

[0093] The second water diversion element 4022 is fixed at the center of the first water diversion element 4021. The first water diversion element 4021 is shaped like a plum blossom petal, while the second water diversion element 4022 is a conical water diverter. When the cooling water falls into the fixed portion 4, it is first dispersed in all directions by the second water diversion element 4022, splashing onto the first water diversion element 4021. The first water diversion element 4021 further disperses the water flow, increasing the number of water dispersions and thus achieving the technical effect of improving the uniformity of the cooling water's fall.

[0094] Preferably, the first water diversion element 4021 has at least 6 petals. The water flow dispersed by the first water diversion element 4021 can fall through the gaps between adjacent petals in the first water diversion element 4021. By limiting the number of petals in the first water diversion element 4021, the water flow dispersion effect can be improved, while also improving the aesthetics of the first water diversion element 4021.

[0095] At the same time, the second water diversion element 4022 Figure 4 As shown, a raised portion is provided in the vertical direction, so that the second water diversion element 4022 can be raised by 5 mm to 10 mm, thereby improving the dispersion effect of the cooling water.

[0096] Of course, in other embodiments, the types of the first water-dividing element 4021 and the second water-dividing element 4022 may be replaced and adjusted as needed.

[0097] Meanwhile, in other embodiments, depending on the design of the nozzle and actual usage, only the first water-dividing element 4021 or only the second water-dividing element 4022 may be provided to break up the flow of the cooling water.

[0098] In addition, a plurality of clamping blocks 4011 are provided on the outer surface of the shell 401, so that the position of the shell 401 can be fixed by the clamping blocks 4011, that is, the shell 401 can be inserted into the hole groove of the required device, and the clamping blocks 4011 are located above the hole groove to prevent the shell 401 from falling, so as to achieve the technical effect of fixing the position stability of the shell 401.

[0099] According to an embodiment of the present invention, on the other hand, a cooling tower is provided, comprising:

[0100] The above-mentioned nozzle;

[0101] The water tray is installed below the nozzle.

[0102] The cooling water can be evenly dispersed through the nozzle, and the nozzle can increase the falling impact force of the cooling water, so as to improve the uniformity of the cooling water falling on the water tray, thereby improving the uniformity of the water distribution on the water tray and further improving the cooling effect of the cooling tower.

[0103] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
