[0002] Cooling towers are highly efficient cooling devices widely used in industrial, residential, and data center air conditioning systems. They utilize evaporative heat dissipation and heat exchange between the coolant and the air to reduce the coolant's temperature. However, heat and mass transfer performance varies significantly at different locations within the cooling tower, resulting in insufficient overall heat transfer efficiency. Utility Model Content

[0003] Embodiments of the present application provide a cooling device, a system, and a data center for improving the heat exchange capacity of the cooling device and improving the heat exchange efficiency.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] In a first aspect, a cooling device is provided, which includes: a tower body; a liquid inlet channel arranged on the tower body; and a first liquid distributor, a first filler, at least one liquid distribution component and a second filler arranged inside the tower body; wherein, the first liquid distributor is connected to the liquid inlet channel; the first filler is arranged below the first liquid distributor; at least one first liquid distribution component is arranged below the first filler; the second filler is arranged below at least one first liquid distribution component; wherein, the first liquid distribution component is used to collect liquid flowing through the first filler and spray the liquid onto the second filler.

[0006] In this embodiment, the first liquid distributor can evenly spray the liquid into the first filler, and the liquid exchanges heat with the air in the first filler, and the temperature of the liquid gradually decreases. After passing through the first filler, a portion of the liquid falls directly into the second filler, and the other portion falls into the liquid distribution component. The liquid distribution component can evenly spray the collected liquid into the second filler. As a result, the liquid undergoes a secondary heat exchange with the air in the second filler to further reduce the temperature. Therefore, in this embodiment, the heat dissipation capacity of the cooling device is improved by providing multiple layers of fillers. Under the premise of the same heat dissipation, the cooling device provided by the embodiment of the present application has improved heat dissipation efficiency compared to a cooling device with only one layer of filler, and the cooling device occupies a smaller area.

[0007] In some optional embodiments, there are multiple first liquid distribution components, and the multiple first liquid distribution components are arranged at intervals in a first direction; the first direction is perpendicular to the arrangement direction of the first filler and the second filler.

[0009] In some optional embodiments, a groove is provided in the water collecting member, with the notch of the groove facing the first filler; and the second liquid distributor is connected to the groove.

[0010] In some optional embodiments, the water collecting member includes a first water collecting plate, a first connecting plate and a second water collecting plate, and the first connecting plate is connected between the first water collecting plate and the second water collecting plate; one end of the first water collecting plate away from the first connecting plate and the other end of the second water collecting plate away from the first connecting plate both extend in a direction close to the first filler, and the first water collecting plate, the first connecting plate and the second water collecting plate form a groove.

[0011] In some optional embodiments, the dimension of the groove opening along the second direction is greater than the dimension of the groove bottom along the first direction; the second direction is parallel to the arrangement direction of the first water collecting plate, the first connecting plate, and the second water collecting plate. Thus, by providing a larger groove opening, more liquid can be collected, while by providing a smaller groove bottom, the collected liquid can be pooled together, thereby reducing coolant loss.

[0012] In some optional embodiments, the cooling device further includes: at least one first water retaining member disposed between the first filler and the at least one first liquid distribution assembly; an edge portion of the first water retaining member is inclined toward the first liquid distribution assembly.

[0013] Thus, after passing through the first filler, part of the liquid falls directly into the liquid distribution assembly, while the other part falls onto the water retaining member and flows into the liquid distribution assembly through the drainage of the water retaining member. This can increase the amount of liquid collected by the liquid distribution assembly and improve the heat exchange capacity of the cooling device.

[0014] In some optional embodiments, the first water retaining member includes a first guide plate and a second guide plate; the first guide plate and the second guide plate are respectively inclined toward the slots of the two adjacent water collecting members, and the edge of the first guide plate and the edge of the second guide plate are respectively located above the slots of the two adjacent water collecting members.

[0015] In some optional embodiments, the first water retaining member further includes a second connecting plate connected between the first guide plate and the second guide plate.

[0016] In some optional embodiments, there are multiple first water retaining parts, and the multiple first water retaining parts and the multiple water collecting parts are alternately arranged up and down, and there is a gap between the water retaining parts and the water collecting parts in the third direction; the third direction is the arrangement direction of the first filler and the second filler.

[0017] In some optional embodiments, the cooling device further comprises an air inlet channel and an air outlet channel disposed on the tower body; the air inlet channel is disposed below the second filler; and the air outlet channel is disposed above the first liquid distributor. Thus, the air inlet channel and the air outlet channel promote air flow and improve heat exchange efficiency.

[0018] In some optional embodiments, the cooling device also includes: a third filler arranged inside the tower body; the third filler is arranged below the second filler and above the air inlet channel; at least one second liquid distribution assembly is arranged between the second filler and the third filler; the second liquid distribution assembly is used to collect liquid flowing through the second filler and spray the liquid onto the third filler.

[0019] In some optional embodiments, the cooling device further includes: at least one second water retaining member disposed between the third filler and the at least one second liquid distribution assembly; an edge portion of the second water retaining member is inclined toward the second liquid distribution assembly.

[0020] In some optional embodiments, the cooling device further comprises: a liquid outlet channel, which is arranged at the bottom of the tower body, so that the cooled liquid is discharged outside the tower body through the liquid outlet channel.

[0021] In a second aspect, a cooling system is provided. The cooling device includes a cooling pump and the cooling device provided in the first aspect. The cooling pump is connected to a liquid inlet channel of the cooling device.

[0022] According to a third aspect, a data center is provided, comprising: a server, and the cooling system provided in the second aspect, wherein the cooling system is used to reduce the temperature of the server.

[0036] With the rapid development of data centers, the demand for shorter construction cycles and higher energy efficiency is increasing. Data centers house numerous server cabinets 300, which generate significant heat when operating for extended periods. To ensure the proper functioning of servers 300, a cooling system 200 is required to maintain the server's temperature.

[0037] The implementation of the technical solution of the present application is further described in detail below with reference to the accompanying drawings.

[0038] With the rapid development of data centers, the demand for shorter construction cycles and higher energy efficiency is increasing. Data centers house numerous server cabinets, and servers 300 generate significant heat when operating continuously. To ensure the proper functioning of servers 300, cooling system 200 is required to maintain the server's temperature.

[0039] The implementation of the technical solution of the present application is further described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1 , Figure 1 Schematic diagram of the application scenario of the cooling system 200 provided in this application. Figure 1 As shown, the cooling system 200 includes a cooling device 100 and a cooling pump 201 .

[0041] The cooling pump 201 is used to drive the cooling liquid to circulate between the cooling device 100 and the server 300. The cooling liquid can exchange heat with the server 300, so that the temperature of the server 300 decreases and the temperature of the cooling liquid increases.

[0042] The cooling device 100 utilizes evaporation of the coolant to dissipate heat and heat exchange when the coolant contacts the air to reduce the temperature of the coolant.

[0043] However, the cooling capacity of the coolant is limited, so in some optional embodiments, the cooling system 200 further includes: a chiller 202 , a heat exchanger 203 , a freezing pump 204 and an air conditioner 205 arranged between the cooling pump 201 and the server 300 .

[0044] The chiller 202 is used to generate refrigerant through a vapor compression refrigeration cycle and supply the refrigerant to the air conditioner 205 for cooling. The chiller 202 can also be called a water-cooled chiller.

[0045] The freezing pump 204 is used to deliver the freezing liquid produced by the chiller 202 to the air conditioner so that the air conditioner performs cooling. As a result, the temperature of the server 300 is reduced under the action of the air conditioner 205, but the temperature of the freezing liquid is increased at the same time.

[0046] The freezing pump 204 is also used to drive the refrigerant with increased temperature to enter the heat exchanger 203. That is, the refrigerant circulates between the chiller 202, the air conditioner 205 and the heat exchanger 203 under the drive of the freezing pump.

[0047] The heat exchanger 203 is used to exchange heat between the freezing liquid and the cooling liquid, so that the temperature of the freezing liquid decreases while the temperature of the cooling liquid increases. For example, the heat exchanger 203 can be a plate heat exchanger.

[0048] The cooling pump 201 is used to drive the coolant to circulate in the cooling device 100 and the heat exchanger 203 .

[0049] The cooling device 100 utilizes evaporation of the coolant and heat exchange between the coolant and the air to reduce the coolant temperature. However, the heat and mass transfer performance of the cooling device 100 varies greatly at different locations, resulting in insufficient overall heat exchange.

[0050] To this end, the present application also provides a cooling device. Figure 2As shown, the cooling device includes: a tower body 101; a liquid inlet channel 102 arranged on the tower body 101; and a first liquid distributor 103, a first filler 104, at least one first liquid distribution component 105 and a second filler 106 arranged inside the tower body 101; wherein, the first liquid distributor 103 is connected to the liquid inlet channel 102; the first filler 104 is arranged below the first liquid distributor 103; the first liquid distribution component 105 is arranged below the first filler 104; the second filler 106 is arranged below at least one first liquid distribution component 105, and the first liquid distribution component 105 is used to collect liquid flowing through the first filler 104 and spray the liquid to the second filler 106.

[0051] In this embodiment, the first liquid distributor 103 can evenly spray the liquid into the first filler 104, and the liquid exchanges heat with the air in the first filler 104, and the temperature of the liquid gradually decreases. After the liquid passes through the first filler 104, a portion falls directly into the second filler 106, and the other portion falls into the first liquid distribution component 105. The first liquid distribution component 105 can evenly spray the collected liquid into the second filler 106. As a result, the liquid undergoes a secondary heat exchange with the air in the second filler 106 to further reduce the temperature. Therefore, in this embodiment, the heat dissipation capacity of the cooling device is improved by setting multiple layers of fillers. Under the premise of the same heat dissipation, compared with the cooling device with only one layer of filler, the heat dissipation efficiency of the cooling device provided by the embodiment of the present application is improved, and the cooling device occupies a smaller area.

[0052] The present application also provides a cooling device. Figure 3 The structural schematic diagram of the cooling device shown is that the cooling device 100 includes: a tower body 101; a liquid inlet channel 102 arranged on the tower body 101; and a first liquid distributor 103, a first filler 104, at least one first water retaining member 107, at least one first liquid distribution component 105 and a second filler 106 arranged inside the tower body 101.

[0053] The first liquid distributor 103 is connected to the liquid inlet channel 102; the first filler 104 is arranged below the first liquid distributor 103; at least one first water retaining member is arranged below the first filler 104, and at least one first liquid distribution component 105 is arranged below at least one first water retaining member 107; the second filler 106 is arranged below at least one first liquid distribution component 105.

[0054] Below Figure 3 Each part of the cooling device 100 shown will be described in detail.

[0055] The first liquid distributor 103 is used to evenly spray the liquid flowing through the liquid inlet channel 102 into the first filler 104. For example, the liquid can be a coolant. The first liquid distributor 103 includes a liquid distribution pipe and multiple nozzles 1031 connected to the liquid distribution pipe. The liquid distribution pipe is connected to the liquid inlet channel 102 to allow the liquid to enter the interior of the tower body 101. The multiple nozzles 1031 are evenly distributed above the first filler 104 to improve the wettability and wetted area of ​​the coolant in the first filler 104, thereby enhancing the cooling effect of the first filler 104.

[0056] It should be noted that the embodiment of the present application does not limit the position of each nozzle 1031. Multiple nozzles 1031 can be set on the same reference surface, for example, the reference surface is parallel to the upper surface of the first filler 104. They can also be set on different reference surfaces, that is, the distances between the multiple nozzles 1031 and the upper surface of the first filler 104 are different. For example, the distance between some nozzles 1031 and the first filler 104 can be a first distance value, and the distance between another part of the nozzles 1031 and the first filler 104 can be a second distance value, and the first distance value and the second distance value are different. Those skilled in the art can set the first liquid distributor 103 according to the spraying requirements, and the embodiment of the present application does not limit this.

[0057] The first filler 104 is used to increase the contact area between the liquid and the air, extending the contact time. The first filler 104 is provided with channels through which the liquid sprayed by the first liquid distributor 103 slowly flows. During this flow, heat is exchanged between the liquid and the air, causing the temperature to drop.

[0058] In some optional embodiments, the first packing 104 includes a plurality of spaced-apart corrugated packing membranes 1041. The corrugated packing membranes 1041 have S-shaped grooves 1042 and convex grooves 1043 spaced apart. The top of the convex groove 1043 of each corrugated packing membrane 1041 is connected to the bottom of the adjacent groove 1042, thereby forming an S-shaped corrugated packing membrane 1041. An S-shaped channel is formed between any two adjacent corrugated packing membranes 1041. The cross-section of the groove 1042 or the convex groove 1043 is a broken line or a trapezoid.

[0059] In this embodiment, the coolant slowly flows down the S-shaped channels in the first packing 104, exchanging heat with the air as it flows downward, thereby reducing the coolant temperature. The S-shaped channels effectively enhance the disturbance of the air and liquid flows within the channels, increasing the gas-liquid heat exchange area while significantly improving the heat transfer efficiency between the air and liquid flows and the packing.

[0060] It should be understood that the above examples are merely examples for a better understanding of the technical solutions of the embodiments of the present application and are not intended to be the sole limitations of the embodiments of the present application. In addition to employing the aforementioned first filler 104 having an S-shaped cross section, the cooling device may also employ other types of first fillers 104 in other embodiments, such as a first filler 104 having a honeycomb cross section, without limitation in the embodiments of the present application.

[0061] However, as the coolant flows downward, it becomes unevenly distributed within the first filler 104, which reduces the heat transfer efficiency of the cooling device. Given the same heat dissipation capacity, a greater temperature difference results in a smaller coolant flow rate, which in turn reduces the coolant spray density. This further degrades the wettability and heat and mass transfer performance of the first filler 104 at different heights. Therefore, with large temperature differences (e.g., a temperature difference of more than 12°C before and after entering the cooling device), the heat transfer efficiency of a single liquid distribution is worse than with smaller temperature differences.

[0062] In view of this, the cooling device 100 in the embodiment of the present application further includes a first liquid distribution assembly 105 below the first filler 104. Thus, after the coolant flows through the first filler 104, a portion falls directly into the second filler 106, while another portion falls into the first liquid distribution assembly 105. The first liquid distribution assembly 105 sprays the collected coolant onto the second filler 106.

[0063] It should be noted that the embodiment of the present application does not limit the number of the first liquid distribution assembly 105. The first liquid distribution assembly 105 can be one or more.

[0064] In some optional embodiments, only one first liquid distribution assembly 105 is provided in the cooling device 100. This first liquid distribution assembly 105 may include a water collection member 1051 and multiple second liquid distributors 1052. The water collection member 1051 is disposed below the first filler 104 and is used to collect the coolant flowing through the first filler 104. The multiple second liquid distributors 1052 are each disposed below and in communication with the water collection member 1051. Each second liquid distributor 1052 is used to evenly spray the coolant collected by the water collection member 1051 into the second filler 106, thereby improving the wettability and wetted area of ​​the coolant in the second filler 106, thereby enhancing the liquid distribution effect of the second filler 106.

[0065] In some specific embodiments, the water collecting member 1051 is provided with a groove, the opening of which faces the first filler 104 , so that at least a portion of the coolant falls into the groove after passing through the first filler 104 .

[0066] For example, Figure 4As shown, the water collecting member 1051 includes a first water collecting plate 10511, a second water collecting plate 10512, a third water collecting plate 10513, a fourth water collecting plate 10514 and a first connecting plate 10515. The first water collecting plate 10511, the second water collecting plate 10512, the third water collecting plate 10513 and the fourth water collecting plate 10514 are arranged around the first connecting plate 10515. That is, the first water collecting plate 10511 and the second water collecting plate 10512 are disposed opposite each other, and the third water collecting plate 10513 and the fourth water collecting plate 10514 are disposed opposite each other, and one end of the first water collecting plate 10511 away from the first connecting plate 10515, one end of the second water collecting plate 10512 away from the first connecting plate 10515, one end of the third water collecting plate 10513 away from the first connecting plate 10515, and one end of the fourth water collecting plate 10514 away from the first connecting plate 10515 all extend toward the first filler 104. Thus, the first water collecting plate 10511, the second water collecting plate 10512, the third water collecting plate 10513, and the fourth water collecting plate 10514 form side walls of the groove. The first connecting plate 10515 is connected between the first water collecting plate 10511 and the second water collecting plate 10512 , and is also connected between the third water collecting plate 10513 and the fourth water collecting plate 10514 , so that the first connecting plate 10515 forms the bottom of the groove.

[0067] In some specific embodiments, the size of the groove opening along the second direction is larger than the size of the groove bottom along the second direction. The second direction is parallel to the arrangement direction of the first water collecting plate 10511, the first connecting plate 10515, and the second water collecting plate 10512. The larger groove opening facilitates collecting more liquid, while the smaller groove bottom facilitates pooling the collected liquid, thereby reducing coolant loss.

[0068] Exemplarily, the third and fourth water collection plates 10513 and 10514 can be trapezoidal. The longer lower base of the trapezoidal water collection plates can serve as the edge of the notch, while the shorter upper base is connected to the first connecting plate 10515. This creates a groove whose notch, along the second direction, is larger than the bottom of the groove, along the second direction. Thus, the angles between the first and second water collection plates 10511 and 10512 and the first connecting plate 10515 are all greater than 90 degrees, which facilitates liquid flow from the first or second water collection plates 10511 and 10512 to the first connecting plate 10515.

[0069] In some specific examples, a plurality of leakage holes are provided in the first connecting plate 10515 , through which the coolant can flow from the water collecting member 1051 to the second liquid distributor 1052 .

[0070] It is understood that in the embodiment of the present application, the second direction is understood to be parallel to the arrangement direction of the first water collecting plate 10511, the first connecting plate 10515 and the second water collecting plate 10512. Here, "parallel" includes the situation described and the situation similar to the situation described, and the range of the similar situation is within the acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the error associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°.

[0071] In some optional embodiments, such as Figure 5 As shown, the cooling device 100 is provided with a plurality of first liquid distribution assemblies 105, which are arranged in a first direction with intervals therebetween. Each first liquid distribution assembly 105 includes a water collecting member 1051 and at least one second liquid distributor 1052. The first direction is perpendicular to the arrangement direction of the first filler 104 and the second filler 106.

[0072] See also Figure 6 1 is a schematic structural diagram of the first liquid distribution assembly, wherein the cooling device 100 is provided with a first liquid distribution assembly 105 - 1 , a first liquid distribution assembly 105 - 2 and a first liquid distribution assembly 105 - 3 . There is a gap between the first liquid distribution assembly 105-1, the first liquid distribution assembly 105-2 and the first liquid distribution assembly 105-3 in the first direction. The first liquid distribution assembly 105-1 includes: a water collecting part 1051-1 and a second liquid distribution device 1052-1; the second liquid distribution device 1052-1 is arranged below the water collecting part 1051-1 and is connected; the first liquid distribution assembly 105-2 includes: a water collecting part 1051-2 and a second liquid distribution device 1052-2; the second liquid distribution device 1052-2 is arranged below the water collecting part 1051-2 and is connected; the first liquid distribution assembly 105-3 includes: a water collecting part 1051-3, a second liquid distribution device 1052-3 and a second liquid distribution device 1052-4; the second liquid distribution device 1052-3 and the second liquid distribution device 1052-3 are arranged below the water collecting part 1051-3 and are connected.

[0073] In this embodiment, by providing multiple first liquid distribution assemblies 105 and leaving gaps between them, resistance to air flow is reduced, further facilitating heat exchange between the coolant and the air. Providing multiple first liquid distribution assemblies 105 also improves the uniformity and flexibility of secondary liquid distribution, further enhancing the heat exchange efficiency of the cooling device.

[0074] It should be noted that "perpendicular" includes the described situation and situations similar to the described situation, and the range of the similar situation is within an acceptable deviation range, where the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "perpendicular" includes absolute perpendicularity and approximately perpendicularity, where the acceptable deviation range for approximately perpendicularity can be, for example, within 5°.

[0075] The water collecting member 1051 in the embodiment of the present application is not limited to the structure provided in the above embodiment. In other examples, the water collecting member 1051 can also be other structures, for example, the water collecting member 1051 is cylindrical or other shapes with water collecting function.

[0076] To further improve the heat transfer capacity of the cooling device, see Figure 5 The cooling device 100 is further provided with a first water retaining member 107 between the first filler 104 and the first liquid distributing assembly 105. The edge portion of the first water retaining member 107 is inclined toward the water collecting member 1051 to facilitate the drainage of liquid into the liquid distributing device.

[0077] In some specific embodiments, there are multiple first water blocking parts 107, and the multiple first water blocking parts 107 and the multiple water collecting parts 1051 are alternately arranged up and down, and there is a gap between the first water blocking parts 107 and the water collecting parts 1051 in the third direction, and the third direction is the arrangement direction of the first filler 104 and the second filler 106.

[0078] In this embodiment, multiple first water retaining members 107 are provided, and a gap exists between the first water retaining members 107 and the water collecting member 1051 in the third direction to ensure that the air can be turned when passing through the first water retaining members 107 and continue to flow toward the first filler 104 .

[0079] In a specific embodiment, each of the first water retaining members 107 includes a first guide plate 1071 and a second guide plate 1072; the first guide plate 1071 and the second guide plate 1072 are respectively inclined toward the slots of the two adjacent water collecting members 1051, and the edges of the first guide plate 1071 and the edges of the second guide plate 1072 are respectively located above the slots of the two adjacent water collecting members 1051.

[0082] The first water retaining member 107-1 includes a first guide plate 1071-1 and a second guide plate 1072-1. The first guide plate 1071-1 is inclined toward the slot of the water collecting member 1051-1, and the edge of the first guide plate 1071-1 is located above the slot of the water collecting member 1051-1; the second guide plate 1072-1 is inclined toward the slot of the water collecting member 1051-2, and the edge of the second guide plate 1072-1 is located above the slot of the water collecting member 1051-2.

The second guide plate 1072-2 is inclined toward the slot of the water collecting member 1051-3, and the edge of the second guide plate 1072-2 is located above the slot of the water collecting member 1051-3.

[0083] Thus, by providing first water retaining members 107 above the gaps between the multiple first liquid distribution assemblies 105, a portion of the coolant, after passing through the first filler 104, will directly fall into the water collecting member 1051 in the first liquid distribution assembly 105. The remaining portion will be blocked by the first water retaining members 107 and, after being guided by the first water retaining members 107, will also flow into the water collecting member 1051. This prevents the coolant from directly falling into the second filler 106, thereby improving the liquid distribution capacity of the first liquid distribution assembly 105 and further enhancing the heat dissipation capacity and efficiency of the cooling device.

[0084] In some optional embodiments, the first water retaining member 107 further includes a second connecting plate connected between the first guide plate 1071 and the second guide plate 1072 .

[0085] For example, Figure 8As shown, the first water retaining member 107-1 includes a first guide plate 1071-1, a second guide plate 1072-1 and a first connecting plate 1073-1. The first connecting plate 1073-1 is located above the gap between the water collecting member 1051-1 and the water collecting member 1051-2. The first guide plate 1071-1 is inclined toward the slot of the water collecting member 1051-1, and the second guide plate 1072-1 is inclined toward the slot of the water collecting member 1051-2. The first water retaining member 107-2 includes a first guide plate 1071-2, a second guide plate 1072-2 and a first connecting plate 1073-2. The first connecting plate 1073-2 is located above the gap between the water collecting member 1051-2 and the water collecting member 1051-3. The first guide plate 1071-2 is inclined toward the slot of the water collecting member 1051-2, and the second guide plate 1072-2 is inclined toward the slot of the water collecting member 1051-3.

[0086] In this way, after passing through the first filler 104, a portion of the coolant will directly fall into the water collection member 1051 of the first liquid distribution assembly 105. The remaining portion will be blocked by the first connecting plate and guided by the first guide plate 1071 or the second guide plate 1072, also flowing into the water collection member 1051. This prevents the coolant from directly falling into the second filler 106, thereby improving the liquid distribution capacity of the first liquid distribution assembly 105.

[0087] The second filler 106 is used to dissipate heat for the second time for the coolant. After the second liquid distribution by the first liquid distribution component 105, the coolant falls into the second filler 106 and flows along the channels in the second filler 106 toward the bottom of the tower body 101. During the flow process, the coolant exchanges heat with the air to further reduce the temperature. Compared with a cooling device with only one layer of filler, in the cooling device provided in the embodiment of the present application, under the action of the first liquid distribution component 105, the coolant in the second filler 106 is more evenly distributed, the wettability of the second filler 106 is higher, and the area of ​​the wetted second filler 106 is also larger, so the heat exchange efficiency of the cooling device is also higher.

[0088] Since the second filler 106 provided in the embodiment of the present application has the same working principle and performs a similar function as the first filler 104 provided in the above embodiment, the structure of the first filler 104 provided in the previous embodiment is also applicable to the second filler 106 and will not be described in detail in this embodiment. In addition, the structure of the second filler 106 in the embodiment of the present application can be the same as or different from the structure of the first filler 104. For example, the first filler 104 and the second filler 106 can both use fillers with an S-shaped cross-section, or they can each use fillers with different structures, for example, using a filler with an S-shaped cross-section as the first filler 104 and a filler with a honeycomb cross-section as the second filler 106.

[0089] In some optional embodiments, such as Figure 9 As shown, the cooling device 100 further includes: an air inlet channel 108 and an air outlet channel 109 provided on the tower body 101 ; the air inlet channel 108 is provided below the second filler 106 ; and the air outlet channel 109 is provided above the first liquid distributor 103 .

[0090] For example, refer to Figure 9 The structural schematic diagram of the cooling device 100 shown in the figure shows that the air inlet channel 108 is arranged at the bottom of the tower body 101 and is connected to the outside world, so as to allow the gas to enter the interior of the tower body 101. The air outlet channel 109 is arranged at the top of the tower body 101 and is connected to the outside world, so as to allow the gas to be discharged from the interior of the tower body 101 into the atmosphere. A fan 1091 is also provided between the air outlet channel 109 and the first liquid distributor 103. The fan 1091 helps to drive the outside air into the interior of the tower body 101 through the air inlet channel, and then flows upward from the bottom of the tower body, passes through the second filler 106, the first liquid distribution component 105, the first water retaining member 107, the first filler 104, and the first liquid distributor 103 in sequence, and is then discharged to the outside of the tower body 101 through the air outlet channel.

[0091] In some optional embodiments, such as Figure 10 As shown, the cooling device 100 further includes a liquid outlet channel 110, which is disposed at the bottom of the tower body 101, for example, below the air inlet channel 108. A water collection tray may also be disposed at the bottom of the tower body 101, connected to the liquid outlet channel 110, to facilitate collection of the coolant passing through the second filler 106. The coolant is then discharged from the tower body 101 through the liquid outlet channel 110.

[0092] The cooling device 100 provided in the embodiment of the present application is provided with an air outlet channel 109 on the top of the tower body 101 and an air inlet channel 108 at the bottom of the tower body, so that air enters the tower body 101 from the outside, so as to facilitate the subsequent heat exchange between the air and the coolant. At the same time, a liquid inlet channel 102 is provided on the top of the tower body, and a first liquid distributor 103, a first filler 104 and a second filler 106 are provided in sequence from top to bottom inside the tower body 101, and a plurality of first water retaining members 107 and a plurality of first liquid distribution components 105 are provided between the first filler 104 and the second filler 106, and a liquid outlet channel 110 is provided at the bottom of the tower body 101. In this way, after the coolant enters the tower body 101 through the liquid inlet channel 102, it undergoes a first heat exchange with the air in the first filler 104, and then is evenly sprayed into the second filler 106 after passing through the first water retaining member 107 and the first liquid distribution component 105, and undergoes a second heat exchange with the air in the second filler 106. After the secondary heat exchange, the coolant temperature meets the requirements and can be discharged outside the tower body 101 through the liquid outlet channel 110. Under the premise of the same heat dissipation, the cooling device provided by the embodiment of the present application can improve the heat dissipation efficiency by 50% and reduce the floor space by 25% compared to a cooling device provided with only one layer of filler.

[0093] It can be understood that the descriptions in the embodiments of the present application such as “one object is below another object”, “one object is above another object”, “the top of the tower body” and “the bottom of the tower body” are all based on the state of the tower body when it is working normally.

[0094] The present application also provides a cooling device, such as Figure 11 As shown, the cooling device 100 includes: a tower body 101; an air outlet channel 109 and a liquid inlet channel 102 arranged on the top of the tower body 101; and a first liquid distributor 103, a first filler 104, at least one first water retaining member 107, at least one first liquid distribution component 105, a second filler 106, at least one second liquid distribution component and a third filler 112 arranged inside the tower body 101; and an air inlet channel 108 and a liquid outlet channel 110 arranged at the bottom of the tower body.

[0095] The first liquid distributor 103 is connected to the liquid inlet channel 102; the first filler 104 is arranged below the first liquid distributor 103; the first water retaining part 107-1 and the first water retaining part 107-2 are arranged below the first filler 104, and the first liquid distribution component 105-1, the first liquid distribution component 105-2 and the first liquid distribution component 105-3 are arranged below the first water retaining part 107-1 and the first water retaining part 107-2; the second filler 106 is arranged below the first liquid distribution component 105-1, the first liquid distribution component 105-2 and the first liquid distribution component 105-3; the second liquid distribution component 113-1, the second liquid distribution component 113-2 and the second liquid distribution component 113-3 are arranged below the second filler 106; the third filler 112 is arranged below the second liquid distribution component 113-1, the second liquid distribution component 113-2 and the second liquid distribution component 113-3.

[0096] In this embodiment, an air outlet channel 109 is provided at the top of the tower body 101, and an air inlet channel 108 is provided at the bottom of the tower body, so that air can enter the interior of the tower body 101 from the outside, so as to facilitate subsequent heat exchange between the air and the coolant. At the same time, a liquid inlet channel 102 is provided at the top of the tower body, and a first liquid distributor 103, a first filler 104, a second filler 106, and a third filler 112 are provided in sequence from top to bottom inside the tower body 101. A plurality of first water retaining members 107 and a plurality of first liquid distribution components 105 are provided between the first filler 104 and the second filler 106, and a plurality of second liquid distribution components 113 are provided between the second filler 106 and the third filler 112. A liquid outlet channel 110 is provided at the bottom of the tower body 101. Thus, after the coolant enters the interior of the tower body 101 through the liquid inlet channel 102, it undergoes the first heat exchange with the air in the first filler 104, and then the coolant is evenly sprayed into the second filler 106 after passing through the first water retaining member 107 and the first liquid distribution assembly 105, and undergoes a second heat exchange with the air in the second filler 106. A portion of the coolant after the second heat exchange falls into the third filler 112, and the other portion is evenly sprayed into the third filler 112 through the second liquid distribution assembly 113. All the coolant undergoes a third heat exchange with the air in the third filler 112. The temperature of the coolant after three heat exchanges meets the requirements, so it can be discharged from the outside of the tower body 101 through the liquid outlet channel 110. Thus, by providing multiple layers of fillers, the cooling efficiency of the cooling device is improved.

[0097] In some optional embodiments, the cooling device 100 further includes at least one second water retaining member, and the at least one second water retaining member is disposed between the second filler 106 and the second liquid distribution assembly 113 .

[0098] Specifically, such as Figure 11As shown, the second water retaining member 114-1 and the second water retaining member 114-2 are arranged between the second filler 106 and the second liquid distribution assembly 113. In this way, a part of the cooling liquid after the second heat exchange falls directly into the third filler 112, and the other part is drained through the second water retaining member 114-1 and the second water retaining member 114-2 and also falls into the second liquid distribution assembly 113. The second liquid distribution assembly 113 sprays all the collected cooling liquid evenly into the third filler 112. All the cooling liquid undergoes a third heat exchange with the air in the third filler 112. The temperature of the cooling liquid after three heat exchanges meets the requirements, so it can be discharged from the outside of the tower body 101 through the liquid outlet channel 110. Thus, by arranging the second water retaining member between the second filler and the third filler, the cooling efficiency of the cooling device is improved.

[0099] It is understood that the above examples are merely examples for better understanding the technical solutions of the embodiments of the present application and are not intended to be the sole limitations of the embodiments of the present application. Those skilled in the art may adjust the amount of packing within the tower body 101 based on cooling requirements. For example, four or more layers of packing may be provided within the tower body 101, with a water retaining member and a liquid distribution assembly provided between two adjacent layers of packing.

[0100] The present application also provides a cooling method, such as Figure 12 As shown, the cooling method includes: the first liquid distributor sprays the liquid flowing into the first liquid distributor into the first filler, so that the liquid exchanges heat with the gas in the first filler and then falls into the second filler and / or the first liquid distribution component, wherein the gas flows from one end of the tower body close to the second filler to the end of the tower body close to the first filler; the first liquid distribution component sprays the collected liquid into the second filler, so that the liquid exchanges heat with the gas in the second filler.

[0101] In this embodiment, the first liquid distributor can evenly spray liquid into the first packing. The liquid exchanges heat with the air in the first packing, gradually reducing the liquid temperature. After passing through the first packing, a portion of the liquid falls directly into the second packing, while another portion falls into the first liquid distribution assembly. The first liquid distribution assembly can evenly spray the collected liquid into the second packing. This liquid then undergoes a secondary heat exchange with the air in the second packing, further reducing its temperature. Thus, the cooling method provided in this embodiment can improve the uniformity of liquid distribution within the packing, thereby enhancing cooling efficiency.

[0102] Since the cooling method provided in the embodiment of the present application corresponds to the cooling devices provided in the above-mentioned embodiments, the previous implementation manner is also applicable to the cooling method provided in this embodiment and will not be described in detail in this embodiment.
