[0038] In the field of computer room air conditioning technology, a cold source unit is usually used to produce low-temperature cooling water to provide cooling capacity for the load in the computer room. The cold source unit, also called a cooling tower (The cooling tower), can realize the heat exchange between the cooling water and the air, dissipate the heat in the cooling water, and reduce the water temperature.

[0039] In the related art, a cold source unit usually has a relatively large external dimension. For example, the overall dimension of a certain cold source unit reaches 6m×6m×4m. Such a cold source unit exceeds the road transportation limit and has problems of being too high and too wide, bringing great inconvenience to transportation.

[0040] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art.

[0041] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0042] On the one hand, as shown in Figure 1 and Figure 2 , this embodiment provides a cold source unit, which includes: a dry cooling module 100 and an evaporative cooling module 200.

[0043] The dry cooling module 100 includes a dry cooling frame assembly 1, and the evaporative cooling module 200 includes an evaporative cooling frame assembly 2; the dry cooling frame assembly 1 is detachably connected to the evaporative cooling frame assembly 2; the dry cooling frame assembly 1 is provided with a dry cooling air inlet 101, and the evaporative cooling frame assembly 2 is provided with an evaporative cooling air outlet 201, and the dry cooling air inlet 101 is communicated with the evaporative cooling air outlet 201.

[0044] In the cold source unit of this embodiment, the dry cooling module 100 is integrally arranged in the dry cooling frame assembly 1, and the evaporative cooling module 200 is integrally arranged in the evaporative cooling frame assembly 2. The dry cooling frame assembly 1 and the evaporative cooling frame assembly 2 are detachably connected. When the dry cooling frame assembly 1 and the evaporative cooling frame assembly 2 are in a connected state, the dry cooling air inlet 101 and the evaporative cooling air outlet 201 are communicated, and the cold source unit can work normally. When the dry cooling frame assembly 1 and the evaporative cooling frame assembly 2 are in a disassembled and separated state, the cold source unit can be separated for transportation, avoiding the problems of being too high and too wide during transportation due to the relatively large single-piece external dimension, and reducing the transportation cost of the cold source unit.

[0045] In the cold source unit of this embodiment, the evaporative cooling module 200 can utilize the evaporative cooling principle to reduce the temperature of the cooling medium flowing through the evaporative cooling module 200, and the dry cooling module 100 can perform convective heat exchange with air by using the internal heat exchange components, and can provide a low-temperature cooling medium for the liquid cooling system.

[0046] In some possible implementation manners, there are various relative positions between the dry cooling module 100 and the evaporative cooling module 200. For example, the dry cooling module 100 is located above the evaporative cooling module 200, or the dry cooling module 100 is located on the horizontal side of the evaporative cooling module 200. The dry cooling module 100 and the evaporative cooling module 200 can be detachably connected in multiple directions and at multiple angles by using the dry cooling frame assembly 1 and the evaporative cooling frame assembly 2, so that the cold source unit can reasonably select different relative positions according to the space requirements, improving the adaptability of the cold source unit.

[0047] Combined with Figure 1 and Figure 2 As shown, in some embodiments, the dry cooling module 100 is located on the top of the evaporative cooling module 200, and the bottom of the dry cooling frame assembly 1 is detachably connected to the top of the evaporative cooling frame assembly 2.

[0048] The dry cooling air inlet 101 is located at the bottom of the dry cooling frame assembly 1, and the evaporative cooling air outlet 201 is located at the top of the evaporative cooling frame assembly 2.

[0049] With the above arrangement, the dry cooling module 100 is arranged on the top of the evaporative cooling module 200, and the dry cooling air inlet 101 and the evaporative cooling air outlet 201 are connected in an up-and-down correspondence. Outdoor air can first flow through the evaporative cooling module 200, and then enter the dry cooling module 100 through the evaporative cooling air outlet 201 and the dry cooling air inlet 101. The dry cooling module 100 and the evaporative cooling module 200 correspond to one air channel, so that only one set of air power components can be arranged, which is beneficial to reducing the number of components of the cold source unit, reducing the cost and volume of the cold source unit.

[0050] Combined with Figure 2 As shown, in some embodiments, the dry cooling frame assembly 1 includes a bottom frame member 11. The bottom frame member 11 is located at the bottom of the dry cooling frame assembly 1, and the bottom frame member 11 is detachably connected to the top of the evaporative cooling frame assembly 2.

[0051] With the above arrangement, the bottom frame member 11 is provided at the bottom of the dry cooling frame assembly 1. The bottom frame member 11 can provide support for the dry cooling module 100 above, facilitating the overall transportation and installation of the dry cooling module 100. The bottom frame member 11 can also conveniently achieve a detachable connection with the top of the evaporative cooling frame assembly 2. Exemplarily, the bottom frame member 11 and the top of the evaporative cooling frame assembly 2 can be detachably connected by using bolt fasteners.

[0052] In some possible implementation manners, a top frame member 26 is provided at the top of the evaporative cooling frame assembly 2, and the bottom frame member 11 of the dry cooling frame assembly 1 can be detachably connected to the top frame member 26. The top frame member 26 can also provide more reliable support for the dry cooling module 100 above.

[0053] Combined withFigure 2 As shown, in some embodiments, the cold source unit further includes a maintenance platform 3; at least a part of the chassis component 11 extends to the outside of the bottom of the dry cooling frame assembly 1; the maintenance platform 3 is located on the chassis component 11 that extends to the outside of the bottom of the dry cooling frame assembly 1.

[0054] In this embodiment, by arranging the maintenance platform 3 on the chassis component 11 outside the bottom of the dry cooling frame assembly 1, it is convenient for maintenance personnel to stand and perform pipeline connection and maintenance on the dry cooling module 100 at a high place, which can reduce the installation and maintenance difficulty of the dry cooling module 100 and provide safety guarantee for maintenance personnel.

[0055] In some embodiments, the cold source unit further includes a maintenance platform 3; at least a part of the top of the evaporative cooling frame assembly 2 is located outside the bottom of the dry cooling frame assembly 1, and the maintenance platform 3 is located on the top of the evaporative cooling frame assembly 2 outside the bottom of the dry cooling frame assembly 1.

[0056] In this embodiment, by arranging the maintenance platform on the top of the evaporative cooling frame assembly 2 outside the bottom of the dry cooling frame assembly 1, it is convenient for maintenance personnel to stand and perform pipeline connection and maintenance on the dry cooling module 100 at the top of the evaporative cooling frame assembly 2, which can reduce the installation and maintenance difficulty of the dry cooling module 100 and provide safety guarantee for maintenance personnel.

[0057] Combined with Figure 9 As shown, in some embodiments, the maintenance platform further includes a guardrail 31 and at least one maintenance ladder 32. The guardrail 31 surrounds the maintenance platform to prevent maintenance personnel from accidentally falling, and the maintenance ladder 32 is used for maintenance personnel to get on and off the maintenance platform. Among them, the number of maintenance ladders 32 can be two. One is connected between the ground and the maintenance platform for maintenance personnel to get on and off between the ground and the maintenance platform, and the other is connected between the maintenance platform and the top of the dry cooling module 100 for maintenance personnel to get on and off between the maintenance platform and the top of the dry cooling module 100.

[0058] Combined with Figure 2 and Figure 3 As shown, in some embodiments, the evaporative cooling frame assembly 2 includes an evaporation chamber 21 and an equipment chamber 22. The equipment chamber 22 is located on one side of the evaporation chamber 21 in the horizontal direction; the dry cooling frame assembly 1 is located on the top of the evaporation chamber 21, and the maintenance platform 3 is located on the top of the equipment chamber 22.

[0059] With the above arrangement, the evaporative cooling frame assembly 2 is divided into an evaporation chamber 21 and an equipment chamber 22. The two chambers are arranged horizontally. The dry cooling module 100 is located at the top of the evaporation chamber 21, facilitating the upward entry of air in the evaporation chamber 21 into the dry cooling module 100. The maintenance platform 3 is arranged at the top of the equipment chamber 22. On the one hand, the equipment chamber 22 can provide reliable support for the maintenance platform. On the other hand, the equipment chamber 22 is usually used to arrange equipment devices such as pipelines and pumps. Arranging the maintenance platform at the top of the equipment chamber 22 is beneficial to reducing the connection of various pipelines, etc.

[0060] Combined with Figure 3 As shown, in some embodiments, the evaporative cooling module 200 further includes an evaporative cooling pipeline, and the dry cooling module 100 further includes a dry cooling pipeline 12. The evaporative cooling pipeline and the dry cooling pipeline 12 are connected by a connecting pipeline 4. The connecting pipeline 4 passes through the equipment chamber 22 and the maintenance platform 3, and at least one flange connection part 41 of the connecting pipeline 4 is located on the maintenance platform 3.

[0061] In this embodiment, the evaporative cooling module 200 circulates the cooling medium through the evaporative cooling pipeline, and the dry cooling module 100 circulates the cooling medium through the dry cooling pipeline 12. After the evaporative cooling pipeline and the dry cooling pipeline 12 are connected by the connecting pipeline 4, the cooling medium can flow through the evaporative cooling module 200 and the dry cooling module 100 in sequence, and two cooling methods can be used for cooling, having better cooling capacity. In addition, the connecting pipeline 4 is arranged to pass through the equipment chamber 22 and the maintenance platform 3, and at least one flange connection part 41 is arranged on the maintenance platform 3. Thus, maintenance personnel can connect and disconnect the pipelines of the evaporative cooling module 200 and the dry cooling module 100 on the maintenance platform 3, which is convenient for installation and disassembly, and further can reduce the difficulty of the combination and separation of the dry cooling module 100 and the evaporative cooling module 200.

[0062] Exemplarily, the flange connection part 41 can be located between the evaporative cooling pipeline and the connecting pipeline 4, or between the dry cooling pipeline 12 and the connecting pipeline 4, or can also be between the sub-pipelines inside the connecting pipeline 4.

[0063] Combined with Figure 4 As shown, in some embodiments, the dry cooling module 100 further includes a dry heat exchanger 13 and at least one fan 14; the dry cooling frame assembly 1 is also provided with a dry cooling air outlet 102; the dry heat exchanger 13 is connected to the dry cooling pipeline 12, the dry heat exchanger 13 is located inside the dry cooling frame assembly 1, and is located between the dry cooling air inlet 101 and the dry cooling air outlet 102; at least one fan 14 is located on the dry cooling air outlet 102. Among them, the dry heat exchanger 13 can be Figure 4 V-shaped, or can also be flat or U-shaped, and the present application does not make any limitation thereto.

[0064] With the above arrangement, the fan 14 can drive air to enter from the dry-cooling air inlet 101. When flowing through the dry-type heat exchanger 13, it absorbs the heat contained in the cooling medium flowing in the dry-type heat exchanger 13, reduces the temperature of the cooling medium, and then blows out from the dry-cooling air outlet 102, realizing the dry cooling of the cooling medium.

[0065] Among them, regarding the number of fans 14, it can be one, two, three, etc., and can be reasonably selected according to actual needs. This application does not limit this.

[0066] Combined with Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, the evaporative cooling module 200 further includes an evaporative cooler 24 and a spraying assembly 25; the evaporative cooling frame assembly 2 is further provided with an evaporative cooling air inlet 202; the evaporative cooler 24 is connected to the evaporative cooling pipeline, the evaporative cooler 24 is located in the evaporative cooling frame assembly 2, and is located between the evaporative cooling air inlet 202 and the evaporative cooling air outlet 201; the spraying assembly 25 is located on one side of the evaporative cooler 24 and is used for spraying cooling water to the evaporative cooler 24. Among them, the evaporative cooling air inlet 202 is located at the lower part of the evaporative cooling module 200. The evaporative cooler 24 can be in the shape of a tube row and is made of copper, stainless steel or aluminum.

[0067] With the above arrangement, when the spraying assembly 25 works, the spraying assembly 25 sprays cooling water towards the evaporative cooler 24. The cooling water evaporates and absorbs heat, taking away the heat contained in the cooling medium flowing in the evaporative cooler 24, reducing the temperature of the cooling medium. At the same time, external air can enter from the evaporative cooling air inlet 202, flow through the evaporative cooler 24 and then flow to the evaporative cooling air outlet 201, and take away the high-temperature water vapor that has absorbed heat and evaporated during this period, thereby realizing the evaporative cooling of the cooling medium. When the spraying assembly 25 does not work, external air can directly absorb the heat contained in the cooling medium flowing in the evaporative cooler 24, reducing the temperature of the cooling medium.

[0068] In some possible implementation manners, referring to Figure 5 and Figure 6As shown, the evaporative cooling module 200 further includes a cooling filler 23. The cooling filler 23 is located below the evaporative cooler 24. After being sprayed onto the surface of the cooling water evaporative cooler 24, a part of it absorbs heat and evaporates into a gaseous state, but another part absorbs heat and still remains in a liquid state. This part of the cooling water will drip from the evaporative cooler 24 onto the cooling filler 23 below. The cooling water continues to penetrate downward in the cooling filler 23. During this process, a part of the cooling water evaporates, taking away the heat of the remaining cooling water, thereby reducing the temperature of the cooling water. In addition, the cooling filler 23 is located between the evaporative cooling air inlet 202 and the evaporative cooling air outlet 201. The outdoor air entering through the evaporative cooling air inlet 202 will flow through the cooling filler 23. The cooling water in the cooling filler 23 evaporates, which can cool and lower the temperature of the outdoor air flowing through.

[0069] Combined with Figure 5 and Figure 6 As shown, in some embodiments, the spraying assembly 25 includes at least one nozzle 251, a spraying pump 252, and a water collecting tank 253. At least one nozzle 251 is located above the evaporative cooler 24, the water collecting tank 253 is located below the evaporative cooler 24, and the spraying pump 252 is respectively connected to the water collecting tank 253 and at least one nozzle 251 through pipelines.

[0070] The evaporative cooling module 200 of this embodiment utilizes the evaporative cooling principle. The spraying assembly 25 uses the nozzle 251 to spray cooling water onto the evaporative cooler 24. The cooling water evaporates and absorbs heat on the surface of the evaporative cooler 24, thereby reducing the temperature of the cooling medium in the evaporative cooler 24. Part of the cooling water will drip onto the cooling filler 23, further evaporating and absorbing heat, reducing the temperature of the cooling water, and at the same time reducing the temperature of the outdoor air flowing through the cooling filler 23, and finally collecting into the water collecting tank 253. Using the spraying pump 252 to supply this part of the cooling water back to the nozzle 251 can realize the recycling of the cooling water.

[0071] Among them, the number of nozzles 251, for example, is one, two, three, etc. Exemplarily, the number of nozzles 251 is multiple, evenly arranged above the evaporative cooler 24, and can spray cooling water evenly onto the surface of the evaporative cooler 24, so as to form a dense and uniform water film on the surface of the evaporative cooler 24.

[0072] In some possible implementation manners, the spraying pump 252 is controlled according to the outdoor environmental temperature. It is closed when the outdoor dry bulb temperature is lower than 10°C. At this time, the evaporative cooler 24 exchanges heat with the surrounding air, and is turned on when it is greater than 10°C to perform evaporative cooling on the evaporative cooler 24, thereby improving the utilization efficiency of the spraying assembly 25 and taking into account the cooling demand and energy consumption.

[0073] Among them, the nozzle 251 may also be referred to as a spray head, a sprinkler, etc.

[0074] In some other possible implementation manners, refer to Figure 6 As shown, the spraying assembly 25 further includes a water replenishing assembly 254 and a water draining assembly 255. The water replenishing assembly 254 can be used to replenish cooling water into the water collecting tank 253 when the cooling water in the spraying assembly 25 is insufficient, and the water draining assembly 255 can be used to drain the cooling water in the water collecting tank 253 when there is more cooling water in the spraying assembly 25 or when replacement is needed. Exemplarily, both the water replenishing assembly 254 and the water draining assembly 255 can include pipelines and corresponding control valves.

[0075] Combined with Figure 5 and Figure 6 As shown, in some embodiments, a water retaining layer 27 is provided at the evaporation cooling air outlet 201. The water retaining layer 27 can prevent the air flowing towards the evaporation cooling air outlet 201 from blowing out the cooling water. Canceling the water retaining layer 27 may cause the air to blow out the cooling water. On the one hand, it will cause loss of cooling water. On the other hand, if the cooling water enters the dry cooling module 100, it may cause corrosion of the dry heat exchanger 13, the fan 14, the dry cooling frame assembly 1, etc.

[0076] Combined with Figure 7 and Figure 8 As shown, in some embodiments, the spraying assembly 25 and the evaporative cooler 24 are located in the evaporation chamber 21, and the spraying pump 252 is located in the equipment chamber 22; a circulation pump 5 is also provided in the equipment chamber 22, and the circulation pump 5 is connected in series with the evaporative cooler 24 by means of pipelines; an inlet and outlet pipe channel 221 is provided on the side wall of the equipment chamber 22, and the inlet and outlet pipe channel 221 is located on any side wall of the equipment chamber 22 along the horizontal direction.

[0077] Through the above arrangement, the equipment chamber 22 can be used to accommodate the circulation pump 5 and the spraying pump 252, isolating the electrical components from the water vapor environment in the evaporation chamber 21, which is beneficial to improving the safety and reliability of the cold source unit. At the same time, since the spraying pump 252 and the circulation pump 5 are arranged in the equipment chamber 22, the corresponding control devices and the like can also be arranged in the equipment chamber 22, which is beneficial to improving the control convenience of the cold source unit.

[0078] In addition, refer to Figure 8 , an inlet and outlet pipe channel 221 can be reserved on any side wall of the equipment chamber 22 along the horizontal direction, so that the connection of the inlet and outlet pipes can be conveniently carried out regardless of the layout orientation of the cold source unit, further improving the adaptability of the cold source unit. Exemplarily, the equipment chamber 22 has three side walls along the horizontal direction, and corresponding inlet and outlet pipe channels 221 can be reserved on all of them.

[0079] On the other hand, the embodiment of the present application provides a liquid cooling system, and the liquid cooling system includes the cold source unit of the present application.
