Description

Technical Field

[0001] This utility model relates to the field of cold liquid distribution technology, and in particular to a cold liquid distribution device. Background Technology

[0002] The Coolant Distribution Unit (CDU) is a core component of industrial cooling systems, responsible for precisely delivering low-temperature coolant to heat sources and recovering high-temperature reflux fluid. With the miniaturization and denser deployment of high-power equipment, the space occupied by cooling systems has become a key factor restricting equipment layout.

[0003] As described above, in the prior art, the coolant distribution device generally uses a fan to exchange heat with the high-temperature return liquid flowing into the heat exchanger, thereby converting the high-temperature return liquid into a low-temperature coolant. Specifically, the fan introduces the cold air in the computer room into the cabinet from the front side of the coolant distribution device cabinet, the cold air flows through the heat exchanger, and finally flows out from the rear side of the cabinet.

[0004] However, in existing technologies, the structural layout of the distribution device responsible for supplying coolant to high-power heat sources has significant shortcomings. Specifically, too many components are arranged adjacent to the side of the heat exchanger furthest from the fan. To ensure heat exchange efficiency, existing technologies typically increase the height of the coolant distribution device's cabinet, causing the components on the fan-free side of the heat exchanger to be offset from the heat exchanger in the cabinet's height direction, thereby improving ventilation on that side. However, increasing the cabinet height results in the coolant distribution device occupying excessive space in the vertical direction, which is detrimental to the spatial arrangement of the cooling system.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

A cavity is formed between the circulation pump and the heat exchanger.

[0019] Preferably, the liquid inlet pipe is connected to the liquid inlet connector provided on the cabinet through the liquid return pipe, and the liquid return pipe is arranged on one side of the heat exchange module along the width direction;

[0020] The liquid outlet pipe is connected to the liquid outlet connector on the cabinet via the liquid supply pipe. The liquid supply pipe is arranged on one side of the heat exchange module along the width direction, and the liquid return pipe is arranged on the same side as the liquid supply pipe.

[0021] The beneficial effects of this utility model are:

[0022] This invention places the circulating pump downstream of the heat exchanger, thereby arranging the circulating pump on the side of the inlet pipe away from the heat exchanger. This improves the ventilation effect of the space in the cabinet located on the side of the heat exchanger away from the radiator.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] Based on the foregoing, existing technologies for coolant distribution devices have significant shortcomings in their structural layout. Specifically, too many components are arranged close to the side of the heat exchanger furthest from the fan. Specifically, coolant distribution devices generally use a circulating pump to provide circulation power, ensuring sufficient and stable coolant flow through the heat source requiring cooling. The circulating pump is typically located on the pipeline used to supply high-temperature return fluid to the heat exchanger. To ensure the integration and space utilization of the coolant distribution device meet requirements, existing technologies place the pipeline for supplying high-temperature return fluid close to the heat exchanger, resulting in the circulating pump and the check valve located upstream of the circulating pump being close to the heat exchanger. Therefore, existing technologies generally design the cabinet to be relatively high, thus misaligning the circulating pump and check valve with the heat exchanger in the cabinet's height direction. This prevents the circulating pump and check valve from obstructing the flow of cool air from inside the heat exchanger. However, increasing the cabinet height leads to the coolant distribution device occupying excessive space in the vertical direction, which is detrimental to the spatial arrangement of the cooling system.

[0039] To resolve the above issues, please refer to [link / reference]. Figs. 1 to 4 This embodiment provides a cold liquid distribution device, which includes a cabinet 1, a heat exchange module 2 and a piping module 3. Both the heat exchange module 2 and the piping module 3 are installed in the cabinet 1. The heat exchange module 2 includes a heat exchanger 21 and a radiator 22. The radiator 22 includes a plurality of fans 221, which are arranged along the length of the cabinet 1 toward the heat exchanger 21.

[0040] The piping module 3 is arranged along the length of the cabinet 1 on the side of the heat exchanger 21 away from the radiator 22. The piping module 3 includes an inlet pipe 31, an outlet pipe 32 and a circulation pump 33. The inlet pipe 31 is connected to the inlet of the heat exchanger 21. The circulation pump 33 is connected between the outlet of the heat exchanger 21 and the outlet pipe 32 and is arranged on the side of the inlet pipe 31 away from the heat exchanger 21. A cavity 11 is formed between the circulation pump 33 and the heat exchanger 21, and the inlet pipe 31 is arranged in the cavity 11.

[0041] Based on the above, in this embodiment, the circulating pump 33 is located downstream of the heat exchanger 21, so that it can be arranged on the side of the inlet pipe 31 away from the heat exchanger 21. Thus, a cavity 11 is formed between the circulating pump 33 and the heat exchanger 21, so that the cold air flowing through the heat exchanger 21 can smoothly enter the space inside the cabinet 1 located on the side of the heat exchanger 21 away from the radiator 22. After being diffused through the cavity 11, the cold air flowing through the heat exchanger 21 can smoothly flow out from the rear side of the cabinet 1.

[0042] That is, by placing the circulating pump 33 on the downstream side of the heat exchanger 21, the circulating pump 33 can be arranged on the side of the inlet pipe 31 away from the heat exchanger 21, thereby improving the ventilation effect of the space in the cabinet 1 on the side of the heat exchanger 21 away from the radiator 22. Thus, this embodiment does not need to increase the height of the cabinet 1, thereby avoiding increasing the space occupied by the coolant distribution device in the height direction, and thus facilitating the spatial arrangement of the cooling system.

[0043] Furthermore, in this embodiment, a first temperature sensor 311, a first pressure sensor 312, a flow meter 313, and a first filter 314 are arranged on the inlet pipe 31 to ensure the safe and reliable operation of the coolant distribution device. The first temperature sensor 311 is used to monitor the temperature of the high-temperature return fluid flowing to the heat exchanger 21 in real time; the first pressure sensor 312 is used to monitor the system pressure in real time; the flow meter 313 is used to monitor the flow rate of the high-temperature return fluid transported along the inlet pipe 31 in real time, thereby confirming whether the coolant circulation is sufficient and avoiding heat dissipation failure of the heat source due to insufficient flow; and the first filter 314 is used to intercept impurities carried in the high-temperature return fluid to ensure the purity of the coolant.

[0044] In addition, a first support frame 315 is provided at the bottom of the liquid inlet pipe 31, which is supported on the bottom wall of the cabinet 1, and a second support frame 321 is provided at the bottom of the liquid outlet pipe 32, which is supported on the bottom wall of the cabinet 1.

[0045] Furthermore, the piping module 3 also includes a water tank 34, which is connected between the outlet of the heat exchanger 21 and the circulating pump 33. The water tank 34 is connected to the outlet of the heat exchanger 21 through a liquid delivery pipe 343 and is used to provide a buffer space to prevent the inlet pipe 31, outlet pipe 32 and other pipes from bursting under pressure. The water tank 34 and the circulating pump 33 are arranged at intervals along the width of the cabinet 1. Thus, the piping module 3 can utilize the width of the cabinet 1 for structural layout, thereby improving the integration and space utilization of the cold liquid distribution device and reducing the space occupied by the cold liquid distribution device.

[0046] Furthermore, since the water tank 34 and the circulating pump 33 are arranged at intervals along the width of the cabinet 1, a channel for air circulation is formed between the water tank 34 and the circulating pump 33, which can further improve the ventilation effect of the space in the cabinet 1 located on the side of the heat exchanger 21 away from the radiator 22, thereby further ensuring that the heat exchange module 2 can fully exchange heat with the high-temperature reflux liquid.

[0047] That is, this embodiment satisfies the requirement of high integration of the coolant distribution device while avoiding affecting the ventilation effect inside the cabinet 1, thereby enabling the coolant distribution device to be designed with a smaller size.

[0048] As described above, the water tank 34 is equipped with a first level gauge 341 and a second level gauge 342. When the first level gauge 341 detects that the liquid level is too low, the control system 5 controls the automatic replenishment of coolant into the water tank 34. When the second level gauge 342 detects that the coolant level in the water tank 34 has reached the required height, the control system 5 controls the cessation of replenishment of coolant into the water tank 34.

[0049] In addition, in this embodiment, the pipeline module 3 includes two circulation pumps 33, which are connected in parallel between the water tank 34 and the outlet pipe 32. It can be understood that the two circulation pumps 33 can adopt a working mode in which one is on and the other is in standby mode, or they can adopt a working mode in which both are on. This embodiment does not make specific restrictions on this.

[0050] Moreover, in this embodiment, the two circulating pumps 33 are arranged at intervals along the width direction of the cabinet 1. That is, in this embodiment, the two circulating pumps 33 are arranged using the width of the cabinet 1, thereby further improving the integration and space utilization of the coolant distribution device, and further reducing the space occupied by the coolant distribution device.

[0051] In addition, since the two circulating pumps 33 are arranged at intervals along the width of the cabinet 1, an air circulation channel is formed between the two circulating pumps 33, which can further improve the ventilation effect of the space on the side of the heat exchanger 21 away from the radiator 22 in the cabinet 1, thereby further ensuring that the heat exchange module 2 can fully exchange heat with the high temperature reflux liquid.

[0052] That is, this embodiment can further achieve the goal of having a high degree of integration of the coolant distribution device while avoiding affecting the ventilation effect inside the cabinet 1, thereby enabling the cooling distribution device to be designed with a smaller size structure.

[0053] Furthermore, the length direction of the water tank 34 is consistent with the length direction of the cabinet 1, that is, the length direction of the water tank 34 is the length direction of the cabinet 1. Therefore, this embodiment can avoid the water tank 34 from obstructing the flow of cold air through the heat exchanger 21 to the rear side of the cabinet 1.

[0054] Furthermore, the length direction of the circulation pump 33 is consistent with the length direction of the cabinet 1, that is, the length direction of the circulation pump 33 is the length direction of the cabinet 1. The circulation pump 33 is connected to the liquid outlet pipe 32 through the connecting pipe 331, and the length direction of the connecting pipe 331 is consistent with the length direction of the cabinet 1, that is, the length direction of the connecting pipe 331 is the length direction of the cabinet 1.

[0055] Therefore, this embodiment can avoid the circulation pump 33 and the connecting pipe 331 from obstructing the flow of cold air through the heat exchanger 21 to the rear of the cabinet 1, thereby allowing the width of the cabinet 1 to be designed to be smaller, and further reducing the space occupied by the cooling distribution device.

[0056] It is worth noting that a one-way valve 3311 is installed on the connecting pipe 331 to prevent coolant backflow.

[0057] Based on the above description, in this embodiment, the coolant distribution device also includes a control system 5. The control system 5 is installed in the cabinet 1 and arranged on top of the circulating pump 33. It can be understood that the control system 5 is also arranged on top of the water tank 34. That is, this embodiment makes full use of the height space of the cabinet 1 to arrange the control system 5 and the pipeline module 3, thereby further improving the integration and space utilization of the coolant distribution device, and thus reducing the space occupied by the coolant distribution device.

[0058] Furthermore, since the control system 5 is located on top of the circulating pump 33, this embodiment can avoid increasing the length of the cabinet 1 while arranging the circulating pump 33 on the side of the inlet pipe 31 away from the heat exchanger 21, thereby further reducing the space occupied by the cold liquid distribution device.

[0059] Based on the above, the control system 5 includes a PLC controller 51 and a power supply 52. ​​The PLC controller 51 and the power supply 52 are also arranged along the width of the cabinet 1. That is, in this embodiment, the structure of the control system 5 is also laid out using the width of the cabinet 1, so that the overall structure of the coolant distribution device is more compact, thereby further improving the integration and space utilization.

[0060] Furthermore, the coolant distribution device also includes an expansion tank 4, which is connected to the water tank 34. The expansion tank 4 and the circulation pump 33 are arranged at intervals along the width of the cabinet 1. Thus, an air circulation channel is formed between the expansion tank 4 and the circulation pump 33, which can further improve the ventilation effect of the space in the cabinet 1 located on the side of the heat exchanger 21 away from the radiator 22, thereby further ensuring that the heat exchange module 2 can fully exchange heat with the high-temperature reflux liquid.

[0061] That is, this embodiment can further achieve the goal of having a high degree of integration of the coolant distribution device while avoiding affecting the ventilation effect inside the cabinet 1, thereby enabling the cooling distribution device to be designed with a smaller size structure.

[0062] Furthermore, the length direction of the expansion tank 4 is also consistent with the length direction of the cabinet 1. Therefore, this embodiment can avoid the expansion tank 4 from obstructing the flow of cold air through the heat exchanger 21 to the rear side of the cabinet 1, thereby allowing the width of the cabinet 1 to be designed to be smaller, and further reducing the space occupied by the cooling distribution device.

[0063] In addition, a first ventilation mesh 12 and a second ventilation mesh 13 are respectively provided on the two side walls of the cabinet 1 along its width direction. The first ventilation mesh 12 and the second ventilation mesh 13 are respectively located on both sides of the pipe module 3 along the width direction of the cabinet 1. A third ventilation mesh 14 is provided on the side wall of the cabinet 1 away from the heat exchange module 2 along its length direction. That is, the third ventilation mesh 14 is located on the rear side of the cabinet 1. The first ventilation mesh 12, the second ventilation mesh 13 and the third ventilation mesh 14 all connect the inner cavity of the cabinet 1 with the outside, thereby improving the ventilation effect inside and outside the cabinet 1, and thus allowing the cooling distribution device to be designed with a smaller structure.

[0064] Based on the above, in this embodiment, the liquid inlet pipe 31 and the liquid outlet pipe 32 are arranged at intervals in the vertical direction, thereby making full use of the height space of the cabinet 1 to arrange the liquid inlet pipe 31 and the liquid outlet pipe 32, and further improving the integration of the cooling distribution device.

[0065] Furthermore, the inlet pipe 31 is connected to the inlet connector 15 on the cabinet 1 via the return pipe 61. The return pipe 61 is arranged on one side of the heat exchange module 2 along the width direction. The outlet pipe 32 is connected to the outlet connector 16 on the cabinet 1 via the supply pipe 62. The supply pipe 62 is arranged on one side of the heat exchange module 2 along the width direction. The return pipe 61 and the supply pipe 62 are arranged on the same side, thereby making full use of the width space of the cabinet 1 to arrange the return pipe 61 and the supply pipe 62.

[0066] Furthermore, a second temperature sensor 621 is installed on the liquid supply pipe 62. The second temperature sensor 621 is used to monitor the temperature of the low-temperature coolant sent to the cooling ring network pipeline in real time. The first temperature sensor 311 and the second temperature sensor 621 work together to ensure that the coolant can effectively and fully dissipate heat from the heat source.

[0067] It is worth noting that in this embodiment, the cold liquid distribution device also includes a drain pipe 63, a discharge pipe 64, and a replenishment pipe 65.

[0068] The vent pipe 63 is connected to the water tank 34. When the system pressure rises abnormally, excess liquid and / or gas are discharged through the vent pipe 63 to prevent the pipe from bursting.

[0069] Specifically, a second pressure sensor 3431 is installed in the liquid delivery pipe 343 connecting the water tank 34 and the heat exchanger 21. The second pressure sensor 3431 is used to monitor the pressure in real time. When the second pressure sensor 3431 detects an abnormal increase in pressure, the control system 5 controls the discharge of excess liquid and / or gas through the vent pipe 63.

[0070] As shown above, the drain pipe 63 is arranged on one side of the heat exchange module 2 along the width direction of the cabinet 1. The drain pipe 63 and the return pipe 61 are arranged on the same side. Thus, this embodiment can make the layout of the return pipe 61, the supply pipe 62 and the drain pipe 63 with the heat exchange module 2 more compact, thereby further improving the integration of the cold liquid distribution device.

[0071] It is worth noting that in this embodiment, the expansion tank 4 is connected to the water tank 34 through the connecting pipe 41, and the discharge pipe 63 is connected to the connecting pipe 41 and can communicate with the connecting pipe 41. Specifically, a safety valve 411 is provided on the connecting pipe 41. The safety valve 411 can control the opening or closing of the discharge pipe 63 and the connecting pipe 41. When the second pressure sensor 3431 detects an abnormal increase in pressure, the control system 5 controls the opening of the discharge pipe 63 and the connecting pipe 41, thereby directionally discharging excess liquid and / or gas through the discharge pipe 63.

[0072] In addition, the drain pipe 64 is connected to the heat exchanger 21, so that the old coolant can be completely drained when the coolant is replaced.

[0073] The replenishment pipe 65 is connected to the inlet pipe 31. Specifically, the end of the inlet pipe 31 closest to the heat exchanger 21 is connected to a branch pipe 316. The branch pipe 316 and the replenishment pipe 65 are respectively provided with a first connector 3161 and a second connector (not shown in the figure). The branch pipe 316 and the replenishment pipe 65 are connected through the first connector 3161 and the second connector, so as to inject new coolant into the coolant distribution device. Moreover, the new coolant flows through the heat exchanger 21, thereby ensuring that the temperature of the new coolant flowing to the cooling ring network pipeline meets the requirements.

[0074] Understandably, a ball valve 3162 is installed on the branch pipe 316, and the control system 5 controls the opening or closing of the branch pipe 316 and the replenishment pipe 65 through the ball valve 3162. Moreover, the replenishment pipe 65 is equipped with a second filter 651 to ensure that the coolant injected into the coolant distribution device is pure coolant.

[0075] Therefore, in this embodiment, the discharge pipe 64 and the replenishment pipe 65 are both arranged on the same side as the return pipe 61, thereby further improving the integration of the cold liquid distribution device.

[0076] Based on the above description, the cabinet 1 is provided with an inlet connector 15, an outlet connector 16, a drain connector 17, a discharge connector 18, and a replenishment connector 19 along one side wall of its length direction. The inlet connector 15 is connected to the return pipe 61, the outlet connector 16 is connected to the supply pipe 62, the drain connector 17 is connected to the drain pipe 63, the discharge connector 18 is connected to the discharge pipe 64, and the replenishment connector 19 is connected to the replenishment pipe 65.

[0077] It should be noted that the specific structure of the water tank 34, the circulating pump 33, all pipes, all joints, all sensors, and all valves mentioned above, as well as the connection methods and operating principles between the pipes, are all existing technologies. Therefore, this embodiment will not elaborate on them.

[0078] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
