Description

Technical Field

[0001] This utility model relates to the technical field of water cooling devices, and in particular to a water cooling tower and a cooling circulation device. Background Technology

[0002] With the development of AI technology, the data throughput of data exchange centers is growing exponentially, and the number and size of electronic devices such as data switches in data centers and communication base stations are increasing. This brings with it the problem of equipment heat dissipation.

[0003] Currently, data exchange centers primarily employ air cooling and water cooling for temperature control. Air cooling uses fans to blow cool air across the equipment surface, carrying away heat. This method is advantageous due to its simple structure and low cost. However, the cooling effect of air cooling is limited, and its heat dissipation capacity depends mainly on the fan airflow and the area of ​​the heat sink fins. For equipment with high heat generation, air cooling often fails to meet the cooling requirements. Furthermore, fans generate significant noise during prolonged operation, affecting the working environment. In addition, fans have a relatively short lifespan, requiring regular replacement and increasing maintenance costs. Moreover, as data exchange centers occupy increasingly larger areas, conventional air cooling methods are insufficient to meet cooling demands. Secondly, water cooling uses coolant circulating in pipes to carry away the heat generated by the equipment, which is then dissipated to the external environment through cooling towers and other equipment. Compared to air cooling, water cooling offers better cooling performance and can handle larger heat loads. However, existing cooling towers also have some shortcomings in practical applications. Existing cooling towers typically employ an open structure, making the coolant susceptible to contamination during contact with air. This leads to a decline in coolant performance and affects heat dissipation, making it difficult to meet the growing heat dissipation demands of devices with high heat generation, such as data switches.

[0004] In view of this, and in order to overcome the shortcomings of the existing system, the water-cooled tower and cooling circulation device of this application are proposed. Utility Model Content

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figures 1 to 4 As shown, a water-cooled tower 10 includes an outer shell 100 and a heat dissipation assembly 200. The heat dissipation assembly 200 includes a heat dissipation inner tube 210, a heat dissipation pump 220, a spray pipe 230, a heat dissipation fan 240, a liquid guide pipe 250, and a plurality of heat dissipation fins 260. The liquid guide pipe 250 is disposed inside the outer shell 100, and both ends of the liquid guide pipe 250 extend to the outer side wall of the outer shell 100. Each heat dissipation fin 260 is spaced apart on the outer side wall of the liquid guide pipe 250, and the surface of each heat dissipation fin 260 is parallel to the vertical direction. The heat dissipation fan 240 is disposed at the top of the outer shell 100. The spray pipe 230 is disposed between the heat dissipation fan 240 and each heat dissipation fin 260. The heat dissipation pump 220 is disposed on the outer side wall of the outer shell 100, and the heat dissipation pump 220 is connected to the outer shell 100 and the spray pipe 230 respectively. The heat dissipation inner tube 210 passes through the liquid guide pipe 250, and one end of the heat dissipation inner tube 210 is connected to the spray pipe 230.

[0030] It should be noted that the heat sinks 260 are arranged equidistantly on the liquid guide tube 250, and the surfaces of the heat sinks 260 are parallel to the vertical direction. The liquid guide tube 250 is used to flow coolant, therefore both ends of the liquid guide tube 250 extend to the outer wall of the housing 100 to facilitate communication with pipes. Furthermore, a cooling fan 240 is installed on the top of the housing 100, which blows air from outside the housing 100 into the space between the heat sinks 260 inside the housing 100. Furthermore, a spray pipe 230 is installed between the cooling fan 240 and each heat sink 260. The spray pipe 230 is connected to the pump outlet of the cooling pump 220 installed on the outer wall of the outer casing 100, and the pump inlet of the cooling pump 220 is connected to the bottom of the outer casing 100. Thus, under the action of the cooling pump 220, water from the bottom of the outer casing 100 is pumped into the spray pipe 230 and then sprayed onto each heat sink 260. In this way, under the action of the cooling fan 240, the cooling pump 220, and the spray pipe 230, the heat transfer of coolant in the liquid guide pipe 250 to each heat sink 260 can be accelerated, thereby accelerating the heat dissipation of each heat sink 260. Furthermore, a heat dissipation inner tube 210 is coaxially installed on the liquid guide pipe 250. The heat dissipation inner tube 210 and the liquid guide pipe 250 are independent structures. One end of the heat dissipation inner tube 210 is connected to the spray pipe 230, and the other end of the heat dissipation inner tube 210 is located inside the outer casing 100. This further accelerates the heat transfer of the liquid in the liquid guide tube 250 to the water in the inner heat dissipation tube 210. Since the liquid guide tube 250 is in a closed environment throughout the heat dissipation process, contamination of the coolant within it is prevented. Furthermore, the combined action of the inner heat dissipation tube 210, the heat pump 220, the spray pipe 230, the cooling fan 240, and the heat sink 260 effectively improves the heat dissipation efficiency of the coolant in the liquid guide tube 250.

[0031] In one embodiment, the heat sink 260 is a steel sheet with a thickness ranging from 3mm to 8mm, and the liquid guiding tube 250 is a copper tube or an aluminum tube. Further, in one embodiment, the distance between any two adjacent heat sinks 260 is 10mm to 50mm.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the outer casing 100 is provided with an inlet pipe 271 and an outlet pipe 272, and the liquid guide pipe 250 is connected to the inlet pipe 271 and the outlet pipe 272 respectively.

[0033] Specifically, to facilitate the installation of the liquid guide pipe 250, an inlet pipe 271 and an outlet pipe 272 are welded onto the outer casing 100, both of which are equipped with flanges. The two ends of the liquid guide pipe 250 inside the outer casing 100 are connected to the inlet pipe 271 and the outlet pipe 272, respectively.

[0034] In one embodiment, multiple liquid guiding tubes 250 are provided, each liquid guiding tube 250 is inserted through each heat sink 260, and there is a gap between each liquid guiding tube 250. One end of each liquid guiding tube 250 is connected to the liquid inlet pipe 271, and the other end of each liquid guiding tube 250 is connected to the liquid outlet pipe 272. Each liquid guiding tube 250 is provided with a heat dissipation inner tube 210.

[0035] It should be noted that this embodiment provides a scheme in which multiple liquid guiding tubes 250 are provided. Specifically, each liquid guiding tube 250 passes through each heat sink 260 at intervals, wherein the heat sink 260 and the liquid guiding tube 250 are fixed together by welding. In this way, the contact area between the liquid guiding tube 250 and the heat sink 260 is increased, thereby improving the heat transfer efficiency between the liquid guiding tube 250 and the heat sink 260, and thus improving the heat dissipation efficiency of the heat sink 260.

[0036] like Figure 2 As shown, in another embodiment, the liquid guide tube 250 includes a first guide tube 251 and a second guide tube 252. The first guide tube 251 and the second guide tube 252 are both inserted through each heat sink 260. One end of the first guide tube 251 is connected to the liquid inlet tube 271, and one end of the second guide tube 252 is connected to the liquid outlet tube 272. The other end of the first guide tube 251 is connected to the other end of the second guide tube 252. A heat dissipation inner tube 210 is inserted inside the first guide tube 251 and the second guide tube 252.

[0037] Specifically, in this embodiment, the liquid guiding pipe 250 consists of a first conduit 251 and a second conduit 252 with their axes parallel to each other. Both the first conduit 251 and the second conduit 252 pass through each heat sink 260, forming a continuous conductive structure. Thus, coolant enters from the inlet pipe 271, flows sequentially through the first conduit 251 and the second conduit 252, and finally connects with the outlet pipe 272. The vertical position of the first conduit 251 and the second conduit 252 is not limited; the first conduit 251 can be located above or below the second conduit 252. This increases the total stroke of the liquid guiding pipe 250, thereby improving the efficiency of coolant dissipation through the heat sinks 260.

[0038] like Figure 3 As shown, in one embodiment, multiple first conduits 251 and second conduits 252 are provided. One end of each first conduit 251 is connected to the inlet pipe 271, and the other end of each second conduit 252 is connected to the outlet pipe 272. Each first conduit 251 is connected to each second conduit 252.

[0039] It should be noted that, in order to further improve the heat dissipation efficiency of the coolant, multiple first conduits 251 and multiple second conduits 252 are provided, and each first conduit 251 is connected to each second conduit 252. In one embodiment, two first conduits 251 and two second conduits 252 are provided.

[0040] like Figure 3 As shown, in one embodiment, a plurality of spray heads 280 are provided at intervals on the spray pipe 230, which are distributed vertically downwards.

[0041] In this way, water can be sprayed onto each heat sink 260 through the spray head 280, thereby improving the heat dissipation efficiency of the heat sink 260.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the heat dissipation assembly 200 further includes a support frame 290, which is disposed inside the housing 100, and a liquid guide tube 250 is disposed on the support frame 290.

[0043] Thus, the liquid guide tube 250 is supported by the support frame 290, so that the heat dissipation body composed of the liquid guide tube 250 and each heat sink 260 is located in the middle of the outer casing 100. This facilitates sufficient contact between air and water and each heat sink 260.

[0044] In one embodiment, two cooling fans 240 are provided, with a gap between them, and the two cooling fans 240 rotate in opposite directions. Thus, one cooling fan 240 is used to blow air from outside the housing 100 into the housing 100, and the other cooling fan 240 is used to extract air from inside the housing 100, thereby accelerating the flow efficiency of water vapor inside the housing 100 and improving the heat dissipation efficiency of the heat sink 260.

[0045] Furthermore, it should be noted that the invention of the water-cooled tower 10 in this application lies in combining air cooling and water cooling to improve the heat dissipation efficiency of the coolant. The coolant acts as a heat dissipation device for electronic equipment, and the coolant and electronic equipment are in an independent state. Secondly, as the area of ​​the data exchange center increases, it is only necessary to connect the water-cooled tower 10 to the heat dissipation equipment of the electronic equipment using pipes, thereby effectively solving the problem of decreased heat dissipation due to heat accumulation as the construction area increases.

[0046] like Figure 1 As shown, in one embodiment, a cooling circulation device 1 includes a water cooling tower 10, a cooling cabinet 20, and a liquid storage tank 30. The cooling cabinet 20 is used to house electronic equipment, and the liquid guide pipe 250, the cooling cabinet 20, and the liquid storage tank 30 are circulated in connection.

[0047] It should be noted that the cooling cabinet 20 is used to install electronic equipment such as data switches. The liquid guide pipe 250, the cooling cabinet 20, and the liquid storage tank 30 are connected in sequence through pipes to achieve circulation. In this way, after the coolant enters the water cooling tower 10 from the liquid storage tank 30 for cooling, it flows into the cooling cabinet 20 to exchange heat with the electronic equipment, then enters the liquid storage tank 30 for storage, and finally enters the water cooling tower 10 again for cooling.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
