Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling, in particular to a quick-plug connector device and an immersion liquid cooling system. Background Art

[0002] As power consumption in advanced computing devices increases significantly, traditional air cooling technology can no longer meet these demands. Consequently, liquid cooling is increasingly being used to dissipate heat from computing devices. Quick-connect connectors, crucial components for connecting liquid cooling systems and cooling equipment, offer the advantage of providing a secure, fast, and leak-free connection, enabling the cooling equipment to cool the coolant in the liquid cooling system after it exchanges heat with heat-generating components. Consequently, quick-connect connectors are increasingly being used in immersion liquid cooling scenarios to achieve coolant circulation.

[0003] Currently, quick-connect connectors generally utilize a self-sealing valve design, typically creating a flow hole at the bottom of the male connector to facilitate fluid flow. However, these self-sealing valves have a very high pressure resistance, and the bottom hole also limits the coolant's flow area, resulting in a small flow area for the quick-connect connector. This requires a higher capacity to overcome the pressure resistance, which in turn increases energy consumption and reduces efficiency. Utility Model Content

[0004] The utility model provides a quick-insert connector device and an immersion liquid cooling system, which can improve working efficiency by reducing the pressure resistance of the quick-insert connector device and increasing the flow area.

[0005] In a first aspect, the present invention provides a quick-connect connector device, comprising a quick-connect male connector and a quick-connect female connector that can be plugged into each other;

[0006] The quick-connect male connector includes a connecting base and a guide pin end, wherein the connecting base is used to connect to the cooling unit, the guide pin end is connected to a side of the connecting base facing away from the cooling unit, and a plurality of first flow holes are circumferentially provided on a side surface of the guide pin end, wherein the first flow holes are connected to the interior of the cooling unit;

[0007] The quick-connect female connector is arranged inside the cabinet, and includes a base, a side plate, an elastic member, and an elastic sheet. The side plate is connected to the base, and the side plate and the base are surrounded to form a receiving space with an opening at one end. The guide pin end can be inserted into the receiving space through the opening;

[0008] The elastic member and the elastic sheet are both arranged in the accommodating space, one end of the elastic member is connected to the base, and the other end is connected to the elastic sheet;

[0009] The side plate is provided with a second flow hole. When the elastic member is in an initial state, the elastic sheet covers the opening. When the guide pin end is inserted into the accommodating space, the elastic member is compressed, and at least a portion of the first flow hole is opposite to the second flow hole.

[0010] The utility model provides a quick-connect connector device, in which the quick-connect female connector is arranged inside the cabinet, and the quick-connect male connector is arranged in the cooling unit. When the cooling unit is connected to the quick-connect female connector through the quick-connect male connector, the cooling unit can be immersed in the coolant of the cabinet. A first flow hole and a second flow hole are respectively provided on the side surfaces of the quick-connect male connector and the quick-connect female connector. When the quick-connect male connector is inserted into the quick-connect female connector, at least a portion of the first flow hole can be directly opposite the second flow hole. Since the quick-connect male connector is connected to the cooling unit, the coolant in the cooling unit can flow into the cabinet through the first flow hole and the second flow hole. Compared with the current straight-through liquid supply method with a bottom opening, since the area of the side is larger than the area of the bottom, the area of the opening can be increased by opening the hole on the side, thereby increasing the flow area. In addition, a self-sealing structure is formed by using an elastic member and an elastic sheet. Since the elastic sheet is thin and light in weight, the elastic member can be more easily compressed and rebounded, thereby reducing the pressure resistance of the quick-connect female connector. Therefore, the quick-insert connector device in the present invention reduces pressure resistance, increases flow area, and is beneficial to improving the working efficiency of the system.

[0011] In some possible implementation schemes, the cross-sectional size of the guide pin end gradually decreases along the direction from the quick-connect male connector to the quick-connect female connector.

[0012] In some possible embodiments, the accommodating space is provided with a guide cavity at one end close to the quick-connect male connector, and a guide channel for passing the guide pin end is provided in the guide cavity, and the cross-sectional size of the guide channel gradually decreases along the direction from the quick-connect male connector to the quick-connect female connector.

[0013] In some possible implementation schemes, the cross-sectional dimension of the end of the guide channel close to the quick-connect male connector is greater than or equal to the cross-sectional dimension of the connecting seat.

[0014] In some possible implementation schemes, when the quick-connect female connector is plugged into the quick-connect male connector, along the plug-in direction of the quick-connect female connector and the quick-connect male connector, the end of the first flow hole away from the base is flush with the end of the second flow hole away from the base, or the end of the first flow hole away from the base is located between the end of the second flow hole away from the base and the base.

[0015] In some possible implementations, the side plate is provided with at least two second flow holes, and the at least two second flow holes are spaced apart along the circumference of the side plate;

[0016] The area of the second flow hole is larger than the area of the first flow hole.

[0017] In some possible implementations, the number of the second flow holes is smaller than the number of the first flow holes, and the size of the second flow holes along the circumferential direction is larger than the size of the first flow holes along the circumferential direction.

[0018] In some possible implementation schemes, the elastic sheet is made of stainless steel.

[0019] In some possible implementation schemes, the elastic member is a spring.

[0020] In a second aspect, the present invention provides an immersion liquid cooling system, comprising a cabinet, a cooling unit, and a quick-connect connector device as described in any possible embodiment of the first aspect;

[0021] The quick-plug male connector of the quick-plug connector device is connected to the cooling unit, and the quick-plug female connector of the quick-plug connector device is connected to the inner wall of the cabinet. The quick-plug male connector and the quick-plug female connector are plugged into each other so that the interior of the cabinet is connected to the interior of the cooling unit, and the cooling unit is immersed in the coolant in the cabinet.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] refer to Figure 1 and Figure 3 The quick-plug connector device 100 in the embodiment of the present invention may include a quick-plug male connector 110 and a quick-plug female connector 120, wherein the quick-plug male connector 110 is connected to the cooling unit 10, and the quick-plug female connector 120 is connected to the cabinet 20. When the quick-plug male connector 110 and the quick-plug female connector 120 are plugged into each other, the quick-plug connector device 100 can be used to connect the interior of the cabinet 20 with the interior of the cooling unit 10, thereby realizing the flow of coolant.

[0032] In a specific implementation, the quick-connect female connector 120 can be disposed on the inner wall of the cabinet 20. When the cooling unit 10 is connected to the quick-connect female connector 120 via the quick-connect male connector 110, the cooling unit 10 can be directly immersed in the coolant within the cabinet 20. It is worth noting that when the coolant within the cabinet 20 dissipates heat from the heating components (e.g., servers) immersed in the coolant, the temperature of the coolant increases due to heat exchange. At this time, the cooling unit 10 can cool the coolant, thereby maintaining the coolant inside the cabinet 20 at a suitable temperature.

[0033] The cooling unit 10 may be, for example, a cold distribution unit. Compared to the conventional arrangement in which the cold distribution unit is disposed outside the cabinet and connected to the cabinet via a pipeline, in this embodiment, the cold distribution unit can be directly immersed in the coolant. This not only prevents leakage but also allows the number of cooling units 10 to be adjusted according to the number of heating elements disposed within the cabinet 10. For example, a plurality of quick-connect female connectors 120 may be pre-installed on the inner wall of the cabinet 10. When the heat generated by the heating elements disposed within the cabinet 10 increases, the number of cooling units 10 may be increased to improve the heat dissipation effect of the cooling units 10 on the coolant within the cabinet 10, thereby achieving high efficiency and convenience.

[0034] like Figure 1 As shown, the quick-connect male connector 110 may include a connecting base 111 and a guide pin end 112. The connecting base 111 is used to connect to the cooling unit 10, and the guide pin end 112 is connected to the side of the connecting base 111 facing away from the cooling unit 10. The connecting base 111 is provided with a connecting hole (not shown) for communicating with the interior of the cooling unit 10. The side of the guide pin end 112 is provided with a plurality of first flow holes 113. The first flow holes 113 are connected to the connecting hole so that the coolant can flow out of the cooling unit 10 through the connecting hole and the first flow holes 113.

[0035] Exemplarily, the guide pin end 112 may include a pressure plate 1121 and an orifice plate 1122, with opposite sides of the orifice plate 1122 connected to the connection base 111 and the pressure plate 1121, respectively. In this case, the interior of the guide pin end 112 can be considered a core-hole structure to provide space for the flow of coolant. A plurality of first flow holes 113 are provided on the orifice plate 1122, and the plurality of first flow holes 113 may be arranged at intervals along the circumference of the orifice plate 1122. In this case, a first column 114 is provided between two adjacent first flow holes 113, so that the first column 114 and the pressure plate 1121 cooperate to ensure the overall strength of the guide pin end 112.

[0036] Continue to refer Figure 1 The quick-connect female connector 120 may include a base 121, a side panel 122, an elastic member 123, and an elastic sheet 124, wherein the base 121 may be fixed to the inner wall of the cabinet, the side panel 122 is connected to the base 121, and cooperates with the base 121 to form a receiving space with an opening at one end (not shown in the figure), and the elastic member 123 and the elastic sheet 124 are both disposed in the receiving space. One end of the elastic member 123 is connected to the base 121, and the other end is connected to the elastic sheet 124. When the elastic member 123 is in the initial state, the distance between the elastic sheet 124 and the base 121 is large, and the elastic sheet 124 can cover the opening of the receiving space, so that the space on the side of the elastic sheet 124 facing away from the base 121 is separated from the receiving space by the elastic sheet 124.

[0037] For reference Figure 1 and Figure 2 The side plate 122 is provided with a second flow hole 1221, which is used to connect the inside of the accommodation space with the outside. The guide pin end 112 can be inserted into the accommodation space through the opening ( Figure 1 (The arrow in the figure indicates the direction in which the quick-connect male connector 110 is inserted into the quick-connect female connector 120.) During this process, the pressure plate 1121 of the guide pin end 112 squeezes the elastic sheet 124, thereby compressing the elastic member 123. When the quick-connect male connector 110 and the quick-connect female connector 120 are in the plugged-in state, at least a portion of the first flow hole 113 can be aligned with the second flow hole 1221, so that the first flow hole 113 and the second flow hole 1221 cooperate to form a flow channel. Since the quick-connect female connector 120 is immersed in the coolant in the cabinet 20 during use, the coolant in the cooling unit 10 can flow into the cabinet 20 through the connecting hole, the first flow hole 113, and the second flow hole 1221 in sequence.

[0038] When the quick-connect male connector 110 is separated from the quick-connect female connector 120, the elastic piece 124 is no longer squeezed by the guide pin end 112. Under the elastic force of the elastic member 123, the elastic piece 124 can be driven to move away from the base 121 until the elastic piece 124 can cover the opening.

[0039] It can be understood that in this embodiment, the first flow hole 113 is set on the side of the quick-connect male connector 110. Since the area of the side is larger than the area of the bottom, when the side plate 122 is opened, the area of the first flow hole 113 can be increased, thereby increasing the flow area. In addition, compared with the existing self-sealing valve, the elastic member 123 and the elastic sheet 124 are used in this embodiment to achieve the self-locking of the quick-connect connector device 100. Since the elastic sheet 124 is thin and lightweight, the elastic member 123 can effectively reduce the pressure resistance when it rebounds to allow the elastic sheet 124 to cover the opening. It can be seen from this that the quick-connect connector device 100 in this embodiment increases the flow area and reduces the pressure resistance, which is conducive to reducing the pressure resistance in the system, thereby improving the efficiency of the entire cooling system.

[0040] In this embodiment, the elastic member 123 may be, for example, a spring, which can further reduce the pressure resistance of the system. The elastic sheet 124 may be, for example, made of stainless steel. This ensures the strength of the elastic sheet 124 while preventing it from rusting due to long-term contact with liquids, thereby preventing the self-locking function of the quick-connect connector device 100 from being affected.

[0041] Continue to refer Figure 1A guide cavity 125 is also provided on one side of the accommodation space near the quick-connect male connector 110. The guide cavity 125 has a guide channel 1251 inside for the guide pin end 112 to pass through. This allows the guide pin end 112 to pass through the guide cavity 125 and then be inserted into the accommodation space. When the quick-connect male connector 110 and the quick-connect female connector 120 are plugged into each other, the guide cavity 125 can also accommodate the connector 111. In other words, the quick-connect male connector 110 can be basically inserted into the quick-connect female connector 120. This can limit the position of the quick-connect female connector 120 and the quick-connect male connector 110, facilitating the relative fixation of the quick-connect male connector 110 and the quick-connect female connector 120.

[0042] like Figure 1 As shown, the guide pin end 112 can be tapered overall. Specifically, the cross-sectional dimensions of the guide pin end 112 gradually decrease along the direction from the quick-connect male connector 110 to the quick-connect female connector 120. It should be noted that the cross-sectional dimensions of the guide pin end 112 can be understood as the cross-sectional dimensions of the guide pin end 112 perpendicular to the direction of insertion between the quick-connect male connector 110 and the quick-connect female connector 120. It is understood that the opening area of the guide cavity 125 is larger than the cross-sectional dimensions of the end of the guide pin end 112 where the pressure plate 1121 is provided. When the quick-connect male connector 110 and the quick-connect female connector 120 are plugged together, the end of the guide pin end 112 where the pressure plate 1121 is provided is first inserted into the guide channel 1251. During this process, high-precision alignment between the guide pin end 112 and the guide cavity 125 is not required. This improves the floating accuracy of the insertion, facilitating faster insertion of the quick-connect male connector 110 into the quick-connect female connector 120.

[0043] Further, refer to Figure 1 and Figure 5 , the cross-sectional dimensions of the guide channel 1251 gradually decrease along the direction from the quick-connect male connector 110 to the quick-connect female connector 120. When the guide pin end 112 is blindly inserted into the guide channel 1251, as it continuously moves toward the elastic sheet 124, the cross-sectional dimensions of the guide channel 1251 gradually decrease, thereby guiding the guide pin end 112 so that the axis of the guide pin end 112 coincides with the axis of the guide channel 1251 as much as possible. In this way, when the guide pin end 112 enters the accommodation space by squeezing the elastic sheet 124 and compressing the elastic member 123, the axis of the guide pin end 112 coincides with the axis of the elastic sheet 124 as much as possible, so that the elastic member 123 can be compressed in the preset direction, which is more conducive to the alignment between the first flow hole 113 and the second flow hole 1221.

[0044] In addition, the cross-sectional dimension of the guide channel 1251 at one end close to the quick-connect male connector 110 may also be greater than or equal to the cross-sectional dimension of the connecting seat 111. This makes it easier for the guide channel 1251 to accommodate the connecting seat 111, so that the connecting seat 111 is placed as a whole in the guide channel 1251, thereby keeping the quick-connect male connector 110 and the quick-connect female connector 120 relatively fixed.

[0045] In some embodiments, as Figure 1 As shown, along the plugging direction of the quick-plug male connector 110 and the quick-plug female connector 120, the second flow hole 1221 can extend toward the base 121 to the end where the side plate 122 and the base 121 are connected, so as to maximize the area of the second flow hole 1221.

[0046] Combine Figure 1 and Figure 2 When the quick-connect male connector 110 and the quick-connect female connector 120 are plugged together, the guide pin end 112 can compress the elastic member 123 to its limit, at which point the elastic sheet 124 can reach its lowest point. Along the plugging direction of the quick-connect male connector 110 and the quick-connect female connector 120, the end of the second flow hole 1221 away from the base 121 can be flush with the end of the first flow hole 113 away from the base 121. Alternatively, the end of the first flow hole 113 away from the base 121 can be located between the end of the second flow hole 1221 away from the base 121 and the base 121, that is, the end of the second flow hole 1221 away from the base 121 is higher than the end of the first flow hole 113. Moreover, in this way, along the plugging direction of the quick-connect male connector 110 and the quick-connect female connector 120, the second flow hole 1221 can completely cover the first flow hole 113, thereby preventing the portion of the side plate 122 located outside the second flow hole 1221 from blocking the first flow hole 113, resulting in a reduction in the flow area of the first flow hole 113.

[0047] Further, refer again to Figure 1 The side plate 122 may be provided with at least two second flow holes 1221. When two or more second flow holes 1221 are provided, the second flow holes 1221 may be spaced apart along the circumference of the side plate 122. A second column 1222 is provided between two adjacent second flow holes 1221, so that the second column 1222 cooperates with the base 121 to ensure the overall strength of the quick-connect female connector 120.

[0048] As mentioned above, the quick-plug male connector 110 can be blindly plugged into the quick-plug female connector 120. By providing a plurality of second flow holes 1221 arranged circumferentially, the facing area between the second flow holes 1221 and the first flow hole 113 can be maximized in the case of blind plugging, thereby ensuring the flow area of the first flow hole 113.

[0049] Based on this, as an optional embodiment, the number of second flow holes 1221 can be less than the number of first flow holes 113, and the circumferential size of the second flow holes 1221 can be larger than the circumferential size of the first flow holes 113. In this way, the area of the second flow holes 1221 can be larger than the area of the first flow holes 113, and in the case of blind insertion, the first flow holes 113 can be more easily aligned with the second flow holes 1221.

[0050] Taking the current quick-connect male connector with a diameter of 65mm as an example, when the bottom hole is originally opened, the flow area of the quick-connect male connector is 3320mm 2 When the quick-connect connector device 100 of this embodiment is used, the side circumference of the quick-connect male connector 110 is 204 mm. 2 Left and right, the total side area is 12000mm 2 The side panel 122 of the quick-connect female connector 120 has an area of 240 mm. 2 Left and right, the total side area is 10200mm 2 Assuming that the quick-connect male connector 110 is provided with four first flow holes 113 and the quick-connect female connector 120 is provided with three second flow holes 1221 , then the number of first columns 114 is four and the number of second columns 1222 is three.

[0051] Furthermore, the height of the quick-connect female connector 120 and the quick-connect male connector 110 are both 50 mm, and it is assumed that the area of the first column 114 is 500 mm. 2 , the area of the second column 1222 is 1240mm 2 , then the total area of the first column 114 is 3720mm 2 The total area of the second column 1222 is 2000mm 2 On this basis, in actual application, taking into account the most undesirable situation, that is, in the case of blind insertion, each second column 1222 is directly opposite the first flow hole 113, and each first column 114 is directly opposite the second flow hole 1221. At this time, the flow area S = the side area S1 of the quick-plug male connector 110 - the total area S2 of the first columns 114 - the total area S3 of the second columns 1222. Based on the above data, it can be inferred that the flow area of the quick-plug connector device 100 in this embodiment is 4500mm when in use, even in the most undesirable situation. 2 Compared with the current quick-connect connector, the flow increase rate is 1.35. It can be seen that the quick-connect connector device 100 in this embodiment can effectively increase the flow area, thereby helping to improve the efficiency of the system.

[0052] Continue to refer Figure 1 The quick-connect female connector 120 is further provided with a mounting structure 126, which can be connected to the side of the side panel 122 facing away from the base 121. The guide cavity 125 can be fixedly connected to the side of the mounting structure 126 facing away from the side panel 122, so as to facilitate the connection between the guide cavity 125 and the side panel 122. The mounting structure 126 can be, for example, a mounting plate with a through hole in the middle thereof, so that the guide channel 1251 inside the guide cavity 125 can communicate with the accommodating space through the through hole.

[0053] Based on the same design concept, reference Figure 1and Figure 4 The present invention also provides an immersion liquid cooling system, which may include a cabinet 20, a cooling unit 10, and a quick-connect connector device 100 as described in the aforementioned embodiment. The quick-connect male connector 110 of the quick-connect connector device 100 is connected to the cooling unit 10, and the first flow hole 113 of the quick-connect male connector 110 communicates with the interior of the cooling unit 10. The quick-connect female connector 120 of the quick-connect connector device 100 is connected to the inner wall of the cabinet 20, and the second flow hole 1221 of the quick-connect female connector 120 communicates with the interior of the cabinet 20.

[0054] When the immersion liquid cooling system in this embodiment operates normally, the quick-plug male connector 110 is plugged into the quick-plug female connector 120, the elastic member 123 is compressed, the first flow hole 113 is connected to the second flow hole 1221, and the coolant in the cooling unit 10 flows into the cabinet 20 through the first flow hole 113 and the second flow hole 1221.

[0055] When the cooling unit 10 is disconnected from the cabinet 20, the quick-plug male connector 110 is separated from the quick-plug female connector 120, and the elastic sheet 124 rebounds to its initial state under the elastic force of the elastic member 123 and covers the opening of the accommodating space, thereby realizing self-locking of the quick-plug connector device 100.

[0056] It is worth noting that Figure 1 and Figure 4 As shown in , the quick-connect female connector 120 can be disposed at the bottom of the cabinet 20. When assembling the cooling unit 10 with the cabinet 20, the hanging ears disposed on the top of the cooling unit 10 can be lifted, and then the cooling unit 10 can be lifted by the hanging ears, and the cooling unit 10 can be blind-plugged into the cabinet 20. Since the quick-connect connector device 100 in this embodiment can be blind-plugged, it not only facilitates faster plugging of the quick-connect male connector 110 and the quick-connect female connector 120, but also reduces the possibility of connection errors and damage, thereby ensuring the operational stability of the entire system.

[0057] In some embodiments, reference Figure 6 The quick-plug female connector 120 can also be set on the side wall of the cabinet 10. At this time, when it is necessary to connect the cooling unit 10 with the inside of the cabinet 20, the cooling unit 10 can be moved horizontally and the quick-plug male connector 110 and the quick-plug female connector 120 can be connected.

[0058] It should be noted that Figure 3 、 Figure 4 as well as Figure 6 The structure shown in the figure is only used to illustrate the connection relationship between the cooling unit 10, the cabinet 20 and the quick-connect connector device 100, and does not represent the actual product size.

[0059] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
