[0084] Referring to Figures 1 to 3 As shown in the figure, the cooling liquid distribution device 100 comprises a control module 110, a power module 120, a heat exchange module 130, a power module 140, and a housing 190. The control module 110, the power module 120, the heat exchange module 130, and the power module 140 are arranged in the housing 190. In some embodiments, the cooling liquid distribution device 100 further comprises a first liquid inlet 101, a first liquid outlet 102, a second liquid inlet 103, and a second liquid outlet 104. The first liquid inlet 101, the first liquid outlet 102, the second liquid inlet 103, and the second liquid outlet 104 can provide working liquid to pass through and are connected to the pipeline channel T in the housing 190.

[0085] The control module 110 is electrically connected to the power module 120 and the power module 140. The control module 110 controls the power module 120 to output corresponding power to the power module 140 according to the actual situation, so as to drive the power module 140 to operate. The power module 140 drives the fluid to flow in the heat exchange module 130 and the pipeline channel. The heat exchange module 130 is connected to the pipeline channel. The heat exchange module 130 is in communication with the first liquid inlet 101, the first liquid outlet 102, the second liquid inlet 103 and the second liquid outlet 104 through the pipeline channel.

[0086] In some embodiments, the control module 110, the power module 120 and the power module 140 are detachably arranged in the shell 190, that is, the control module 110, the power module 120 and the power module 140 can be plugged into the shell 190 according to the actual situation. The user can detach the control module 110, the power module 120 and the power module 140 from the shell 190 by the handle arranged on the control module 110, the power module 120 and the power module 140.

[0087] In some embodiments, the power module 120 includes a first power module 122 and a second power module 124. The user can detach the first power module 122 and the second power module 124 from the shell 190 by the handle arranged on the first power module 122 and the second power module 124.

[0088] As shown in Figures 1 to 3 The heat exchange module 130 includes a heat exchanger 131 and a liquid storage unit 132. The power module 140 is arranged on one side of the liquid storage unit 132 of the heat exchange module 130. The power module 140 and the liquid storage unit 132 are in fluid communication with each other.

[0089] Specifically, referring to Figure 7When the cooling liquid distribution device 100 is applied in the cabinet cooling system 700, the first liquid inlet 101 provides the low temperature working liquid from the ice water tower 730 without waste heat into the cooling liquid distribution device 100, the second liquid inlet 103 receives the high temperature working liquid from the server device 740, the first liquid outlet 102 provides the high temperature working liquid with waste heat from the low temperature working liquid entered from the first liquid inlet 101 through the heat exchanger 131, and the second liquid outlet 104 provides the low temperature working liquid from the high temperature working liquid entered from the second liquid inlet 103 through the heat exchanger 131, the liquid storage unit 132 and the power module 140, and then the low temperature working liquid exits the cooling liquid distribution device 100 to be delivered to the cold plate 750 in thermal contact with the server device 740. In other words, the path from the first liquid inlet 101 to the first liquid outlet 102 is the external circulation path of the cooling liquid distribution device 100, and the path from the second liquid inlet 103 to the second liquid outlet 104 is the internal circulation path of the cooling liquid distribution device 100. The high temperature and the low temperature are relative comparison or reference, for example, the high temperature working liquid is high temperature relative to the low temperature working liquid, and the high temperature working liquid is high temperature relative to the low temperature working liquid.

[0090] In some embodiments, the heat exchanger 131 is, for example, a plate heat exchanger, which provides a place for heat exchange between the low temperature working liquid entered from the first liquid inlet 101 and the high temperature working liquid entered from the second liquid inlet 103, and transfers the heat from the server device 740 to the low temperature working liquid, but the present application is not limited thereto. In addition, the liquid storage unit 132 is used to temporarily store the working liquid passing through the heat exchanger 131 for buffering, for example, a water storage tank or a liquid storage tank with no specific geometric shape, which is made of a material that does not react with the working liquid, for example, stainless steel. Furthermore, the power module 140 uses power to deliver the low temperature working liquid from the liquid storage unit 132 to the second liquid outlet 104 through the integrated pipe 145 to provide the low temperature working liquid required by the cold plate 750.

[0091] Referring to Figure 6In some embodiments, the control module 110 comprises a main control unit 111, and the power module 140 comprises a first pump 141, a second pump 142, a third pump 143, and a fourth pump 144. In some embodiments, the main control unit 111 of the control module 110 is capable of adjusting the operating performance of the pumps of the power module 140 according to the operating condition of the power module 140. For example, when the first pump 141, the second pump 142, the third pump 143, and the fourth pump 144 of the power module 140 are all operating normally, the power module 140 outputs a first analog signal, such as a rotation speed signal of the first pump 141, the second pump 142, the third pump 143, and the fourth pump 144, to the main control unit 111 of the control module 110. After receiving the first analog signal, the main control unit 111 converts the first analog signal into a digital signal by using an analog / digital converter built in the main control unit 111. The main control unit 111 determines that the first pump 141, the second pump 142, the third pump 143, and the fourth pump 144 of the power module 140 are all operating normally according to the digital signal. Then, the main control unit 111 processes and calculates the digital signal, converts the processed and calculated digital signal into a second analog signal, such as a pulse width modulation signal, by using a digital / analog converter built in the main control unit 111, and outputs the second analog signal to the power module 140 to control the first pump 141, the second pump 142, the third pump 143, and the fourth pump 144 of the power module 140 to maintain the current rotation speed.

[0092] When one of the first pump 141, the second pump 142, the third pump 143 and the fourth pump 144 of the power module 140 is abnormal, for example, the rotation speed of the first pump 141 is greater than 7000 rpm, for example, the case of idling, or the rotation speed is lower than 1000 rpm, for example, the case of stopping running or being detached, the power module 140 outputs a first analog signal to the main control unit 111 of the control module 110. After the main control unit 111 receives the first analog signal, the main control unit 111 converts the first analog signal into a digital signal through the analog / digital converter built in the main control unit 111. The main control unit 111 judges that the running condition of the first pump 141 of the power module 140 is abnormal according to the digital signal. Then, the main control unit 111 processes and calculates the digital signal, converts the processed and calculated digital signal into a second analog signal, for example, a pulse width modulation signal, through the digital / analog converter built in the main control unit 111, and outputs the second analog signal to the second pump 142, the third pump 143 and the fourth pump 144 of the power module 140, so as to adjust the rotation speed of the second pump 142, the third pump 143 and the fourth pump 144, for example, to increase the rotation speed by 10% to 20% or to run at full speed. At this time, the power module 120 simultaneously provides the corresponding required power to the second pump 142, the third pump 143 and the fourth pump 144 of the power module 140, so as to maintain the normal operation of the cooling liquid distribution device 100, thereby ensuring that the server equipment 740 connected with the cooling liquid distribution device 100 does not overheat.

[0093] It is worth mentioning that when the main control unit 111 is abnormal and fails or is detached from the shell 190 for maintenance, the power module 140 will not be able to receive the second analog signal output from the main control unit 111. In order to avoid the power module 140 from stopping running in such a case and affecting the normal operation of the cooling liquid distribution device 100, at this time, the power module 120 directly outputs power to the power module 140, so that the first pump 141, the second pump 142, the third pump 143 and the fourth pump 144 in the power module 140 can still run at full speed in the case that the main control unit 111 fails, thereby maintaining the normal operation of the cooling liquid distribution device 100 and ensuring that the server cabinet connected with the cooling liquid distribution device 100 does not overheat.

[0094] It should be particularly pointed out that in some embodiments, the power module 140 is configured with four pumps, such as the first pump 141, the second pump 142, the third pump 143 and the fourth pump 144, which are only part of the embodiments of the present application. In another part of the embodiments, the power module 140 can also be configured with more pumps. In the case of being configured with multiple pumps, the main control unit 111 of the control module 110 can adjust the running performance according to the running condition of each pump.

[0095] It is worth noting that, referring to Figure 5 The integrated pipe 145 of the cooling liquid distribution device 100 is arranged between the first pump 141, the second pump 142, the third pump 143, the fourth pump 144 of the power module 140 and the second liquid outlet 104. The integrated pipe 145 has a plurality of working liquid inlets and an integrated outlet 505, and the plurality of working liquid inlets include a first inlet 501, a second inlet 502, a third inlet 503 and a fourth inlet 504, which are respectively connected to the first pump 141, the second pump 142, the third pump 143 and the fourth pump 144 to collect the working liquid of the first pump 141, the second pump 142, the third pump 143 and the fourth pump 144, and then transmit the working liquid to the second liquid outlet 104 through the integrated outlet 505.

[0096] In some embodiments, the integrated outlet 505 to the second liquid outlet 104 also includes a flow meter 153 to measure the flow of working liquid delivered to the server device 740, so that the control module 110 can adjust the operation of the power module 140 according to the flow information of the flow meter 153 to control the flow. Since the cooling liquid distribution device 100 disclosed in the present application optimizes the flow path of the liquid storage unit 132 and the integrated pipe 145, for example, a plurality of inlets are collected and guided to a single outlet, effectively reducing fluid resistance, so that the flow can be increased by more than 2 times, thereby reaching 60LPM (liters per minute), and achieving a maximum heat dissipation capacity of about 100kW (kilowatts). Since the internal and external cooling cycles are independent of each other in a double circuit, there is no risk of water leakage, and it is also beneficial for subsequent maintenance and management.

[0097] In some embodiments, the cooling liquid distribution device 100 disclosed in the present application is further designed with a liquid replacement module 180 including a cooling liquid replacement inlet 182 and a cooling liquid replacement outlet 184 arranged on the front panel 107. In addition, the cooling liquid replacement inlet 182 is connected to the liquid storage unit 132 by the pipe passage T, and the cooling liquid replacement outlet 184 is connected to the pipe passage T of the second liquid inlet 103 by the pipe passage T, so that the user can directly receive the high-temperature working liquid from the server device 740 through the second liquid inlet 103 and discharge the working liquid through the cooling liquid replacement outlet 184 to the internal circulation, and input fresh working liquid into the liquid storage unit 132 through the cooling liquid replacement inlet 182 to supplement the discharged working liquid, thereby directly replacing the working liquid from the front of the server rack without stopping the machine, effectively maintaining the stability of the quality of the working liquid.

[0098] In addition, the plurality of independent pumps have current overload protection devices, so that the overall flow can be effectively increased, and the failure risk of the cooling liquid distribution device 100 can be effectively reduced.

[0099] In some embodiments, the liquid replacement module 180 further comprises a cooling liquid discharge port 186 disposed on the rear face plate 108 and connected to the integrated tube 145 by a cooling liquid discharge line 187, preferably connected to the integrated tube 145 and the lowest point of the liquid in the overall cooling liquid distribution device 100, more preferably the lowest point of the working liquid in the cooling liquid distribution device 100, to completely discharge the working liquid from the cooling liquid distribution device 100 and thus completely replace the working liquid.

[0100] In some embodiments, the cooling liquid distribution device 100 further comprises an emergency switch 192 mounted on the front face plate 107 and electrically connected to the control module 110 to avoid the failure of network communication connection resulting in the inability to turn on or off the system. In addition, the emergency switch 192 disposed on the front face plate 107 can also facilitate the user to turn on or off the cooling liquid distribution device 100 in front of the server cabinet.

[0101] In addition, in some embodiments, the pumps in the power module 140, such as the first pump 141, the second pump 142, the third pump 143, and the fourth pump 144, are connected by quick connectors and line passages, which can prevent the working liquid from leaking out of the line passages when the power module 140 is detached from the housing 190.

[0102] It should be particularly noted that, in some embodiments, the cooling liquid distribution device 100 is cooled by the ice water tower 730 located on the outer circulation path to form low-temperature working liquid from the high-temperature working liquid with waste heat discharged from the first liquid outlet 102, but the present application is not limited thereto. In other embodiments, the ice water tower 730 can also be replaced by other cooling devices, such as a fan, a water cooling module, or a water cooling module with a fan, which can also achieve the technical effect of cooling the high-temperature working liquid with waste heat discharged from the first liquid outlet 102. For example, when the fan replaces the ice water tower 730, the fan can blow air to cool the outer circulation path. When the water cooling module replaces the ice water tower 730, the water cooling module is connected to the outer circulation path to cool the working liquid in the outer circulation path. When the water cooling module with a fan replaces the ice water tower 730, the water cooling module is connected to the outer circulation path to cool the working liquid in the outer circulation path, and the fan blows air to cool the water cooling module.

[0103] As Figure 6As shown, in some embodiments, the cooling fluid distribution system 600 comprises a cooling fluid distribution device 100 and an external monitoring center 610. The cooling fluid distribution device 100 further comprises a sensing module 150, a flow regulating module 160 and a display module 170. The control module 110 further comprises an extension control unit 112. The sensing module 150 is connected to the first inlet 101, the second inlet 103, the first outlet 102, the second outlet 104 or the pipe channel, so that the sensing module 150 can sense the sensing data of the working fluid in the first inlet 101, the second inlet 103, the first outlet 102, the second outlet 104 or the pipe channel. The sensing data can be temperature, flow rate or pressure, for example. The flow regulating module 160 is connected to the pipe channel, so that the flow regulating module 160 can control the flow rate of the working fluid in the pipe channel. The main control unit 111 of the control module 110 is electrically connected to the sensing module 150 and the flow regulating module 160, and the main control unit 111 is connected to the external monitoring center 610 through the extension control unit 112. The main control unit 111 receives the sensing data measured by the sensing module 150 and transmits the sensing data to the external monitoring center 610 through the extension control unit 112. The monitoring center 610 sends control instructions to the extension control unit 112 according to the sensing data and transmits the control instructions to the main control unit 111. The main control unit 111 controls the operation of the flow regulating module 160 according to the control instructions. The display module 170 is used to display the sensing data, such as temperature, flow rate or pressure, sensed by the sensing module 150. In some embodiments, the sensing module 150 comprises a temperature sensor 151, a pressure sensor 152 or a flow meter 153, the flow regulating module 160 is a proportional valve, for example, and the display module 170 comprises a liquid crystal display, which is preferably arranged on the front panel 107 to facilitate the user to observe, but the present application is not limited thereto. The sensing module 150, the flow regulating module 160 and the display module 170 can be selected according to the requirements, which do not deviate from the concept and protection scope of the present application.

[0104] In some embodiments, the first inlet 101, the second inlet 103, the first outlet 102 and the second outlet 104 are designed with quick connectors to quickly connect to the pipe channel outside the cooling fluid distribution device 100, and can prevent the working fluid from leaking out of the pipe channel.

[0105] It is worth mentioning that in some embodiments, in addition to being able to adjust the operating performance of the power module 140 according to the operating condition of the power module 140, the main control unit 111 can also adjust the operating performance of the power module 140 according to the sensing data of the working liquid in the first liquid inlet 101, the second liquid inlet 103, the first liquid outlet 102, the second liquid outlet 104 or the pipeline channel sensed by the sensing module 150. For example, when the high-temperature working liquid, i.e. the working liquid that absorbs the waste heat of the server equipment 740, entering from the second liquid inlet 103 has a temperature higher than 80°C, the main control unit 111 controls the first pump 141, the second pump 142, the third pump 143 or the fourth pump 144 of the power module 140 to increase the speed, for example, to increase the speed by 10%-20%. At this time, the power module 120 simultaneously provides the corresponding required power to the power module 140, thereby ensuring that the server equipment 740 connected with the cooling liquid distribution device 100 will not be overheated.

[0106] Referring again to Figure 7 In some embodiments, the cabinet cooling system 700 further comprises a network switch 720 and a cloud control center 710, and the server equipment 740 comprises a temperature sensor 742 and a control unit 744. The temperature sensor 742 can sense the temperature of the server equipment 740 in real time to obtain temperature data, and the control unit 744 receives the temperature data and transmits the temperature data to the cloud control center 710 through the network switch 720, thereby storing the temperature data sensed by the temperature sensor 742 in the cloud control center 710. The control module 110 of the cooling liquid distribution device 100 can read the real-time temperature data of the server equipment 740 stored in the cloud control center 710 through the network switch 720, and the main control unit 111 of the control module 110 determines whether the server equipment 740 has an overheating condition according to the read temperature data. If the main control unit 111 determines that the server equipment 740 has an overheating condition, the main control unit 111 sends a control signal to the power module 140, so that the first pump 141, the second pump 142, the third pump 143 or the fourth pump 144 of the power module 140 increases the speed, thereby ensuring that the server equipment 740 connected with the cooling liquid distribution device 100 will not be overheated.

[0107] Therefore, the cooling liquid distribution device can effectively integrate the working liquid output by multiple pumps, improve the flow of the working liquid, and further improve the cooling capacity of the cooling liquid distribution device.
