[0055] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.
[0056] In one specific embodiment, such as Figures 1-4 As shown, a modular liquid-cooled cold plate includes a thermal management system module and a cold management system module. The thermal management system module and the cold management system module are connected by a metal waterproof connector. The cold management system module includes a refrigeration system, a chilled water system, a detection system, and a connecting device. The refrigeration system includes a liquid-cooled cold plate 10, and the liquid-cooled cold plate 10 has a cold flow channel 13 with corrugated grooves inside. The connecting device includes an inlet manifold 6, a connecting hose 7, an outlet manifold 8, and upper and lower connecting pipes 9. The detection system includes an inlet control detection module 14 and an outlet control detection module 15. The inlet manifold 6 is connected to the inlet control detection module 14, and the outlet manifold 8 is connected to the outlet control detection module 15.
[0057] With the above settings, the present invention adopts an upper part as a thermal management system module and a lower part as a cold management system module. The two parts are isolated to prevent the mixing of hot and cold. The cold flow channel 13 of the liquid cooling plate 10 adopts a wave channel groove design to improve heat exchange efficiency. The inlet control detection module 14 and the outlet control detection module 15 are used to monitor parameters such as the flow rate, temperature, and pressure of the refrigerant at the inlet and outlet of the liquid cooling plate 10, thereby monitoring the cooling efficiency of the liquid cooling plate 10.
[0058] In some specific implementations, the thermal management system module includes a thermal management system, a primary side system, and a secondary side system. The thermal management system includes a radiator 1, a heat exchanger, a cooling fan 2, an inlet water collection assembly 3, an outlet water collection assembly 4, and a circulating pump 5.
[0059] Furthermore, the thermal management system is connected to the primary system. The liquid-cooled plate 10 transfers heat to the outlet manifold 8 through the connecting hose 7, and then to the radiator 1 through the circulation pump 5, and then the heat is carried away by the cooling fan 2.
[0060] Furthermore, the thermal management system is connected to the secondary system. The liquid-cooled plate 10 transmits heat to the outlet manifold 8 through the connecting hose 7, and then to the heat exchanger through the circulating pump 5. The heat exchanger is connected to the chilled water system, and the heat exchanger and the chilled water system exchange heat to remove heat.
[0061] In the above scheme, the thermal management system can be connected to either the primary or secondary system. If connected to the primary system, it can be combined with a hot aisle return air system. Heat passes through the refrigerant in the liquid-cooled plate 10, through the connecting hose 7 to the outlet manifold 8, and then through the circulation pump 5 to the radiator 1. The cooling fan 2 carries away the heat with air. The top of the cabinet can be fitted with a sealed hot aisle leading to the outside or the air conditioning inlet. The refrigerant in the radiator 1 then circulates back to the liquid-cooled plate 10 through the inlet manifold 6 and the circulation pump 5.
[0062] If connected to a secondary system, the heat exchanger is combined with the chilled water system. Heat is transferred through the refrigerant in the liquid-cooled plate 10, through the connecting hose 7 to the outlet manifold 8, and then through the circulation pump 5 to the heat exchanger. The heat exchanger is connected to the chilled water system. Heat is transferred to the outside through heat exchange between the chilled water and the refrigerant. The refrigerant in the heat exchanger then circulates back to the liquid-cooled plate 10 through the inlet manifold 6 and the circulation pump 5.
[0063] In some specific implementations, the refrigeration system consists of at least two sets, which are connected to the inlet main pipe 6 and the outlet main pipe 8 via upper and lower set pipes 9.
[0064] In some specific implementations, the refrigeration system includes 14 liquid-cooled cold plates 10.
[0065] In some specific embodiments, the liquid-cooled cold plate 10 is provided with an inlet connector 11 and an outlet connector 12 at both ends. The inlet connector 11 is connected to the inlet main pipe 6, and the outlet connector 12 is connected to the outlet main pipe 8.
[0066] With the above configuration, the liquid-cooled cold plate 10 is equipped with quick connectors at both ends for easy connection to the inlet and outlet manifolds. The liquid-cooled cold plate 10 has a corrugated grooved cold flow channel 13 inside, using liquid as the heat transfer medium to flow through the internal channels of the cold plate, achieving non-contact liquid cooling of the heat source through heat transfer. It is suitable for heat dissipation of high power consumption or high heat density components.
[0067] In some specific implementations, the outlet main pipe 8 and the inlet main pipe 6 are provided with 14 branch pipes, and are connected to the liquid cooling plate 10 through connecting hoses 7.
[0068] In some specific implementations, the thermal management system module is placed in the upper cabinet and the cold management system module is placed in the lower cabinet, with the upper and lower cabinets connected together.
[0069] In some specific implementations, the upper cabinet has a height of 500mm, a width of 850mm, and a depth of 1200mm, while the lower cabinet has a height of 1500mm, a width of 850mm, and a depth of 1200mm.
[0070] In the above scheme, the refrigeration management system module includes two sets of refrigeration systems, each set containing 14 liquid-cooled cold plates 10, for a total of 28 cold plates. Each inlet / outlet main pipe 6 contains 14 branch pipes, which can be quickly connected to the liquid-cooled cold plates 10 using connecting hoses 7. Through the inlet control detection module 14 and the outlet control detection module 14, the flow rate, temperature, pressure, and other parameters of the refrigerant at the 14 inlet / outlet points of the liquid-cooled cold plates 10 are monitored, thereby monitoring the refrigeration efficiency of each liquid-cooled cold plate 10 in different zones. The two sets of modules are connected to the inlet main pipe 6 at the front right and the outlet main pipe 8 at the rear right inside the cabinet via upper and lower group pipes 9, thus the cabinet can be divided into 28 zones.
[0071] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
