[0002] A rack coolant distribution unit (Rack CDU) is a water-cooled device used on server equipment. This coolant distribution unit can directly bring coolant to a server rack through multiple pipes at the same time to cool electronic components in the server rack, such as central processing units. The coolant distribution unit can continuously deliver coolant to the server rack through related pumps, closed loops and back-end heat exchange mechanisms to remove heat from the server rack.

[0003] However, due to the rapid changes in technology, the cabinets used to store server equipment have a variety of specifications and designs in order to meet various different needs. However, the heat dissipation requirements of each server cabinet with different specifications are also different. However, the existing cabinet-type coolant distribution device cannot cope with the sudden abnormal overheating caused by various specifications of server cabinets or server equipment to regulate the flow of working liquid, which will lead to insufficient heat dissipation capacity for certain specifications of server cabinets or certain sudden abnormal situations. Therefore, how to improve the above problems has become the focus of relevant personnel in this field. Summary of the invention

Figure 5 The functional block diagram is as follows: Figure 6 is a schematic diagram of the configuration of the coolant distribution device applied to the cabinet cooling system, and Figure 7 Schematic side view of the liquid storage unit.

[0074] See also Figures 1 to 6 , Figure 1 It is a schematic diagram of the three-dimensional structure of a cooling liquid distribution device according to an embodiment of the present invention. Figure 2 for Figure 1 A three-dimensional structural schematic diagram of the coolant distribution device from another perspective is shown. Figure 3 for Figure 1 A schematic top view of a coolant distribution device is shown. Figure 4 for Figure 1 A schematic diagram of some components of the coolant distribution device is shown. Figure 5 for Figure 1The functional block diagram of the coolant distribution device is shown. Figure 6 for Figure 1 The coolant distribution device shown is applied to the configuration diagram of the cabinet type cooling system. It should be noted that in order to clearly illustrate the internal components of the coolant distribution device 1, Figures 1 to 4 The coolant distribution device 1 shown omits the housing cover.

[0075] like Figures 1 to 6 As shown, the coolant distribution device 1 includes a housing 10, a control module 11, a power module 12, a heat exchange module 13 and a power module 14. The control module 11, the power module 12, the heat exchange module 13 and the power module 14 are all arranged in the housing 10. In some embodiments, the coolant distribution device 1 further includes a first liquid inlet I1, a second liquid inlet I2, a first liquid outlet O1 and a second liquid outlet O2. The first liquid inlet I1, the second liquid inlet I2, the first liquid outlet O1 and the second liquid outlet O2 can provide working liquid to pass through and are connected to the pipeline channel T located in the housing 10. The control module 11 is electrically connected to the power module 12 and the power module 14. The control module 11 controls the power module 12 to output corresponding electricity to the power module 14 according to the actual needs, thereby driving the power module 14 to operate. The power module 14 drives the fluid to flow in the heat exchange module 13 and the pipeline channel T. The heat exchange module 13 is connected to the pipeline channel T. The heat exchange module 13 is interconnected with the first liquid inlet I1, the second liquid inlet I2, the first liquid outlet O1 and the second liquid outlet O2 through the pipeline channel T.

[0076] In some embodiments, the control module 11, the power module 12 and the power module 14 are all detachably configured in the shell 10, that is, the control module 11, the power module 12 and the power module 14 can be plugged in and out of the shell 10 according to actual needs, and the user can use the handles configured on the control module 11, the power module 12 and the power module 14 to remove the control module 11, the power module 12 and the power module 14 from the shell 10 respectively.

[0077] like Figures 1 to 6 As shown, the heat exchange module 13 includes a heat exchanger 131 and a liquid storage unit 132. The power module 14 is disposed on one side of the liquid storage unit 132 of the heat exchange module 13, and the power module 14 and the liquid storage unit 132 are in fluid communication with each other. Figure 6When the cooling liquid distribution device 1 is applied to the cabinet cooling system 2, the first liquid inlet I1 provides the low-temperature working liquid C1 without waste heat from the ice water tower 23 to enter the cooling liquid distribution device 1, the second liquid inlet I2 receives and collects the high-temperature working liquid H1 after passing through the server equipment 22, the first liquid outlet O1 provides the low-temperature working liquid C1 entering from the first liquid inlet I1 to pass through the heat exchanger 131 to form the high-temperature working liquid H2 with waste heat to be discharged, and the second liquid outlet O2 provides the high-temperature working liquid H1 entering from the second liquid inlet I2 to pass through the heat exchanger 131, the liquid storage unit 132 and the power module 14 in sequence and the low-temperature working liquid C2 that is cooled and leaves the cooling liquid distribution device 1 to be transported to the cold plate 21 in thermal contact with the server equipment 22. In other words, the path from the first liquid inlet I1 to the first liquid outlet O1 is the external circulation path of the cooling liquid distribution device 1, and the path from the second liquid inlet I2 to the second liquid outlet O2 is the internal circulation path of the cooling liquid distribution device 1. The high temperature and low temperature mentioned here are all relative comparisons or references. For example, the high temperature working liquid H2 is at a high temperature relative to the low temperature working liquid C1 , and the high temperature working liquid H1 is at a high temperature relative to the low temperature working liquid C2 .

[0078] 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 C1 entering from the first liquid inlet I1 and the high-temperature working liquid H1 entering from the second liquid inlet I2, and transfers the heat from the server device 22 carried by the high-temperature working liquid H1 to the low-temperature working liquid C1. In some embodiments, the heat exchanger 131 in the coolant distribution device 1 is preferably considered to occupy a small space, so the heat exchanger 131 disclosed in the present invention is not limited to a plate heat exchanger. In addition, the liquid storage unit 132 is used to temporarily store the working liquid passing through the heat exchanger 131 for buffering purposes, such as a water tank or liquid storage tank of any geometric shape, which can be made of a material that does not react with the working liquid, such as stainless steel. Furthermore, the power module 14 uses power to output the low-temperature working liquid C2 from the liquid storage unit 132 to the second liquid outlet O2 to provide the low-temperature working liquid C2 required by the cold plate 21.

[0079] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the control module 11 includes a main control unit 111, and the power module 14 includes a first pump 141 and a second pump 142. In some embodiments, the main control unit 111 of the control module 11 can adjust the operating performance of the pump of the power module 14 according to the operating conditions of the power module 14. For example, when the first pump 141 and the second pump 142 of the power module 14 are both operating normally, the power module 14 outputs a first analog signal, such as a speed signal of the first pump 141 or the second pump 142, to the main control unit 111 of the control module 11. After receiving the first analog signal, the main control unit 111 converts the first analog signal into a digital signal through an analog / digital converter built into the main control unit 111. The main control unit 111 determines that the operation of the first pump 141 or the second pump 142 of the power module 14 is normal based on the digital signal. The main control unit 111 processes the digital signal and then converts the processed digital signal into a second analog signal, such as a pulse width modulation signal, through a digital / analog converter built into the main control unit 111, and outputs it to the power module 14 to control the first pump 141 or the second pump 142 of the power module 14 to maintain the current rotation speed.

[0080] When one of the first pump 141 and the second pump 142 of the power module 14 is abnormal, for example, the speed of the first pump 141 is greater than 7000 rpm, such as idling, or the speed is less than 1000 rpm, such as stopping or being disassembled, the power module 14 outputs a first analog signal to the main control unit 111 of the control module 11. After receiving the first analog signal, the main control unit 111 converts the first analog signal into a digital signal through an analog / digital converter built into the main control unit 111. The main control unit 111 determines the operation of the first pump 141 of the power module 14 according to the digital signal. If the main control unit 111 processes the digital signal, it converts the processed digital signal into a second analog signal, such as a pulse width modulation signal, through a digital / analog converter built into the main control unit 111, and outputs it to the second pump 142 of the power module 14 to control the second pump 142 to increase the speed, such as increasing the speed by 10% to 20% or running at full speed. At this time, the power module 12 also provides the required power to the second pump 142 of the power module 14, thereby maintaining the normal operation of the coolant distribution device 1 to ensure that the server equipment 22 connected to the coolant distribution device 1 will not overheat.

[0081] It is worth mentioning that when the main control unit 111 fails due to an abnormality or is removed from the shell 10 for maintenance, the power module 14 will not be able to receive the second analog signal output from the main control unit 111. In order to prevent the power module 14 from stopping in such a situation and affecting the normal operation of the coolant distribution device 1, at this time, the power module 12 will directly output power to the power module 14, so that the first pump 141 and the second pump 142 in the power module 14 can still maintain full speed operation when the main control unit 111 fails, thereby maintaining the normal operation of the coolant distribution device 1 and ensuring that the server cabinet connected to the coolant distribution device 1 will not overheat.

[0082] It should be noted that in some embodiments, the power module 14 is configured with two pumps, such as the first pump 141 and the second pump 142, which are only some embodiments of the present invention. In another embodiment, the power module 14 can also be configured with more than two pumps. In the case of configuring more than two pumps, the main control unit 111 of the control module 11 can still adjust the operating performance according to the operating conditions of each pump. For example, in the case where the power module 14 is configured with three pumps, if two of the pumps are abnormal, the main control unit 111 controls the other pump that is not abnormal to increase the speed. If only one of the pumps is abnormal, the main control unit 111 controls the other two pumps that are not abnormal to increase the speed.

[0083] In addition, in some embodiments, the pumps in the power module 14, such as the first pump 141 and the second pump 142, are connected to the pipeline channel T through a quick connector Q. When the power module 14 is disassembled and pulled out of the housing 10, the quick connector Q can prevent the working fluid from leaking out of the pipeline channel T.

[0084] It should be particularly noted that, in some embodiments, the coolant distribution device 1 dissipates heat from the high-temperature working liquid H2 with waste heat discharged from the first liquid outlet O1 through an ice-water tower 23 located on the external circulation path to form a low-temperature working liquid C1, but the present invention is not limited to this. In other embodiments, the ice-water tower 23 can also be replaced with other cooling devices, such as a fan, a water-cooling radiator module, or a water-cooling radiator module with a fan, which can also achieve the technical effect of dissipating heat from the high-temperature working liquid H2 with waste heat discharged from the first liquid outlet O1. For example, when the ice-water tower 23 is replaced by a fan, the fan can be used to blow air to the external circulation path to dissipate heat. When the ice-water tower 23 is replaced by a water-cooling radiator module, the water-cooling radiator module is connected to the external circulation path to dissipate heat from the working liquid in the external circulation path. When the ice-water tower 23 is replaced by a water-cooling radiator module with a fan, the water-cooling radiator module is connected to the external circulation path to dissipate heat from the working liquid in the external circulation path, and the fan is used to blow air to the water-cooling radiator module to dissipate heat.

[0085] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the coolant distribution device 1 further includes a sensing module 15, a flow regulating module 16 and a display module 17. The control module 11 further includes an extended control unit 112. The sensing module 15 can be connected to the first liquid inlet I1, the second liquid inlet I2, the first liquid outlet O1, the second liquid outlet O2 or the pipeline channel T, so that the sensing module 15 can sense the sensing data of the working liquid in the first liquid inlet I1, the second liquid inlet I2, the first liquid outlet O1, the second liquid outlet O2 or the pipeline channel T. The sensing data is, for example, a temperature value, a flow value or a pressure value. The flow regulating module 16 can be connected to the pipeline channel T, so that the flow regulating module 16 can control the flow rate of the working liquid flowing in the pipeline channel T. The main control unit 111 of the control module 11 is electrically connected to the sensing module 15 and the flow regulating module 16, and the main control unit 111 is connected to the external monitoring center 100 through the extension control unit 112. The main control unit 111 receives the sensing data measured by the sensing module 15 and transmits the sensing data to the external monitoring center 100 through the extension control unit 112. The monitoring center 100 sends a control instruction to the extension control unit 112 according to the sensing data and transmits it to the main control unit 111. The main control unit 111 controls the operation of the flow regulating module 16 according to the control instruction. The display module 17 is used to display the sensing data such as the temperature value, flow value or pressure value sensed by the sensing module 15. In some embodiments, the sensing module 15 includes a thermal sensor, a flow meter or a pressure meter, the flow regulating module 16 includes a proportional valve, and the display module 17 includes a liquid crystal display, but the present invention is not limited thereto. The sensing module 15, the flow regulating module 16 and the display module 17 can select appropriate components according to the needs, which do not deviate from the concept and protection scope of the present invention.

[0086] It is worth mentioning that in some embodiments, in addition to being able to adjust the operating performance of the power module 14 according to the operating conditions of the power module 14, the main control unit 111 can also adjust the operating performance of the power module 14 according to the sensing data of the working fluid in the first liquid inlet I1, the second liquid inlet I2, the first liquid outlet O1, the second liquid outlet O2 or the pipeline channel T sensed by the sensing module 15. For example, when the temperature of the high-temperature working fluid H1 entering from the second liquid inlet I2, that is, the working fluid that absorbs the waste heat of the plurality of server devices 22, is higher than 80°C, the main control unit 111 controls the first pump 141 or the second pump 142 of the power module 14 to increase the speed, for example, by 10% to 20%. At this time, the power module 12 simultaneously provides the power required to the power module 14, thereby ensuring that the server devices 22 connected to the coolant distribution device 1 will not overheat.

[0087] like Figure 6 As shown, in some embodiments, the server device 22 includes a temperature sensor 221 and a control unit 222, and the cabinet cooling system 2 further includes a network switch 24 and a cloud control center 25. The temperature sensor 221 can sense the temperature of the server device 22 in real time to obtain temperature data, and the control unit 222 receives the temperature data and transmits the temperature data to the cloud control center 25 through the network switch 24, thereby storing the temperature data sensed by the temperature sensor 221 in the cloud control center 25, and the control module 11 of the coolant distribution device 1 can read the real-time temperature data of the server device 22 stored in the cloud control center 25 through the network switch 24, and the main control unit 111 of the control module 11 determines whether the server device 22 is overheated according to the read temperature data. If the main control unit 111 determines that the server device 22 is overheated, the main control unit 111 sends a control signal to the power module 14, so that the first pump 141 or the second pump 142 of the power module 14 increases the speed, thereby ensuring that the server device 22 connected to the coolant distribution device 1 does not overheat.

[0088] See also Figure 7 , which is Figure 1 The side view of the liquid storage unit is shown in FIG. Figure 7 Please also refer to Figures 1 to 5In some embodiments, the sensing module 15 further includes a plurality of liquid level gauges 151, 152, 153, 154. The liquid level gauges 151, 152, 153, 154 are disposed in the liquid storage unit 132, and the liquid level gauges 151, 152, 153, 154 are sequentially distributed on the side surface F3 of the liquid storage unit 132 from the top surface F1 to the bottom surface F2 of the liquid storage unit 132, from top to bottom. The configuration positions of the liquid level gauges 151, 152, 153, 154 respectively represent that the working liquid in the liquid storage unit 132 is at a high water level, a normal water level, a low water level, or a warning water level. When the water level of the working fluid in the liquid storage unit 132 is lower than the liquid level gauge 153, that is, the water level of the working fluid in the liquid storage unit 132 is lower than the low water level standard, at this time, the main control unit 111 of the control module 11 cannot receive the sensing signal from the liquid level gauge 153, and then determines that the water level of the working fluid in the liquid storage unit 132 is too low. The main control unit 111 sends a control signal to the power module 14, so that the first pump 141 or the second pump 142 of the power module 14 reduces the speed, thereby avoiding the first pump 141 or the second pump 142 of the power module 14 from idling due to the low water level of the working fluid in the liquid storage unit 132, so as to achieve the purpose of protecting the power module 14.

[0089] In view of this, the coolant distribution device disclosed in the present invention can effectively adjust the operating performance of another pump of the power module according to the operating condition of one pump of the power module, can also adjust the operating performance of the pump of the power module according to the sensing data of the working liquid, can also adjust the operating performance of the pump of the power module according to the temperature data of the server, and can also adjust the operating performance of the pump of the power module according to the liquid height in the liquid storage unit. In addition, when the main control unit is abnormal or is pulled out from the shell, the power module can directly output power to the power module, so that the pump of the power module runs at full speed.

That is, simple equivalent changes and modifications made according to the claims of the present invention and the content of the invention description are still within the scope of the patent of the present invention.
