Detailed Implementation

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Please refer to this as well. Figures 1-6 This utility model discloses a unidirectional immersion liquid-cooled data center cabinet, which is mainly used for long-term low-temperature protection of running servers. Its main structure includes a cabinet 1, an immersion liquid cooling box 3, and a cooling circulation unit 5.

[0032] In this embodiment, a lifting and hoisting device 2 is installed on the top of the cabinet 1. The lifting and hoisting device 2 is a movable robotic arm used for disassembling and installing the server 7 and the baffle 6. Several baffles 6 are provided inside the immersion liquid cooling box 3, such as... Figure 1 Several baffles 6 divide the interior of the immersion liquid cooling tank 3 into several compartments, each containing a separate server 7. The immersion liquid cooling tank 3 is located in the middle of the cabinet 1, and a lifting device 2 is installed above it for removing the server 7 for maintenance. A distributor 4 is installed at the bottom of the immersion liquid cooling tank 3, which is connected to the input of the cooling circulation unit 5. Because the immersion liquid cooling tank 3 contains coolant, the coolant submerges the server 7 within the compartment, thus absorbing heat through the coolant. Simultaneously, the output of the cooling circulation unit 5 is connected to the distributor 4, allowing the cooling circulation unit 5 to replenish coolant to any individual compartment via the distributor 4.

[0033] In some embodiments, the immersion liquid cooling box 3 includes a box body 31, a motherboard slot 32 and an overflow interlayer 34. A plurality of baffle grooves 35 are vertically arranged inside the box body 31. The baffle grooves 35 are suitable for inserting baffles 6. In this embodiment, guide strips adapted to the baffle grooves 35 are provided on both sides of the baffles 6. The baffles 6 are provided with handles. The lifting and hoisting device 2 is suitable for pulling the handles to assemble and disassemble the baffles 6.

[0034] On the other hand, the exterior of the enclosure 31 is provided with reinforcing ribs 33 to enhance the structural strength of the enclosure 31. Inside the enclosure 31, a motherboard slot 32 is provided between two adjacent baffle slides 35. The motherboard slot 32 is used to install the server 7, which allows the server 7 to be accurately inserted into the interface along the motherboard slot 32, and the interface is connected to the data cable through the wire hole 36 provided above the motherboard slot 32.

[0035] In this embodiment, an overflow interlayer 34 is provided on the front end face of the housing 31. The height of the overflow interlayer 34 is lower than the height of all partitions, thereby enabling the overflow interlayer 34 to communicate with all partitions and to communicate with the input end of the cooling circulation unit 5.

[0036] In a specific embodiment of this utility model, the cooling circulation unit 5 includes a casing 51 and a heat exchanger 53. An electric pump 52 is installed at the bottom of the casing 51. The electric pump 52 drives the coolant to flow. The electric pump 52 is connected to the controller 54 by circuit. The electric pump 52 is controlled by a frequency converter. Therefore, the operating power of the electric pump 52 can be adjusted by the controller 54 to ensure that the coolant flow rate meets the cooling requirements.

[0037] In this embodiment, the input end of the heat exchanger 53 is connected to the electric pump 52, and the output end is connected to the overflow jacket 34. The heat exchanger 53 is installed inside the casing 51, thereby exchanging heat with the external cooling medium through the heat exchanger 53 to transfer the heat dissipated by the server 7 to the outside.

[0038] In some embodiments, the controller 54 includes a flow rate sensor 541, a microcontroller 542, and a control panel 543. A flow rate sensor 541 is installed in each of the dispensing tanks 43. Both the electric pump 52 and the flow rate sensor 541 are connected to the microcontroller 542. Thus, using the value measured by the flow rate sensor 541 as input, the microcontroller 542 controls the power of the electric pump 52 in response. The coolant flow rate can be maintained by inputting a program into the microcontroller. The microcontroller 542 is electrically connected to the control panel 543 for manual adjustment.

[0039] Specifically, expanding further outwards, in the data center, the prediction of coolant flow in enclosure 31 involves multiple factors, including equipment load, environmental conditions, and coolant properties. Regarding the pre-operation and frequency setting and operation of the variable frequency pump 52 in the data center, sensors detect and record the operating parameters of server 7, and using the current coolant physical properties, the system, based on deep data analysis, determines the heat generated by the server operation. The AI ​​system continuously optimizes and improves prediction and control strategies through reinforcement learning to minimize energy consumption. Thus, the system can use a genetically optimized artificial neural network model to utilize the measured data to determine the highest, lowest, and average temperatures of heat-generating components, the heat transfer coefficient of the liquid at different locations, and the coolant pressure at different locations inside enclosure 31, the flow resistance of the coolant in the channels, etc., and predict the overall operating conditions of the liquid-cooled enclosure. Based on these parameters, the required current coolant flow rate for the server can be calculated, and precise control can be achieved through negative feedback adjustment using the predicted values. When all server units inside the liquid-cooled enclosure are in operation, the system accurately predicts the relevant data required for cooling each server and adjusts it in real time.

[0040] In some embodiments, the liquid dispenser 4 includes a dispensing base 41 and a dispensing plate 44. The dispensing base 41 has several dispensing grooves 43 corresponding to partitions inside. The dispensing plate 44 is located at the upper end of the dispensing base 41, and its end face has several through holes 46. The dispensing grooves 43 communicate with the corresponding partitions through the through holes 46. In this embodiment, each dispensing groove 43 is equipped with an independent solenoid valve 45. The solenoid valve 45 is electrically connected to the microcontroller 542 of the controller 54, and is connected in series on the infusion pipe 42. When the server 7 is not running, the electric pump 52 stops, and the electric solenoid valve 45 closes.

[0041] In this embodiment, temperature sensors are installed in both the heat exchanger 53 and any one of the distribution tanks 43, and these temperature sensors are all connected to the microcontroller 542. It should be noted that when the equipment starts running, the power of the electric pump 52 is set to maximum to ensure the coolant flow rate. As the server operates, the coolant temperature slowly increases, the resistance coefficient decreases, and the coolant flow rate increases. However, once a certain point is reached, an excessively fast coolant flow rate can lead to insufficient heat exchange between the server and the coolant. Therefore, temperature sensors are added for monitoring. Specifically, temperature sensors are installed at key locations in the cooling system (such as the inlet and outlet of the server 7) to monitor coolant temperature changes in real time. The heat exchange efficiency is evaluated by calculating the temperature difference between the server and the coolant. Simultaneously, a flow rate sensor 541 is used for flow monitoring to accurately measure the coolant flow rate and evaluate the heat exchange environment. Based on this, if the temperature difference is too large, it indicates insufficient heat exchange.

[0042] At this point, a dynamic adjustment method can be used: based on the monitored temperature and flow data, the pump power can be dynamically adjusted using a PID (proportional-integral-derivative) control algorithm. This ensures that the coolant flow rate meets the cooling requirements without causing insufficient heat exchange.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
