[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0035] In the description of the present application, it should be noted that the terms "upper", "lower", "inner" and "outer" are used for the purpose of simplifying the description, but do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0036] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0037] like Figure 1 The cold plate type liquid cooling charging module shown in the figure comprises a box body 1 and a box cover 12. A cavity 11 is provided in the box body 1 to accommodate a heating component 2. A hollow cold plate 7 is provided in the cavity 11. Figure 2 As shown, the heating component 2 is arranged between the bottom wall 13 of the box body 1 and the hollow cold plate 7. A liquid inlet 3 and a liquid outlet 5 are opened on the side wall of the box body 1. The liquid inlet 3 is provided with a liquid inlet pipe 4, and the liquid outlet 4 is provided with a liquid outlet pipe 5. One end of the hollow cold plate 7 is connected with the liquid inlet 3, and the other end is connected with the liquid outlet 5. The coolant flows into the hollow cold plate 7 from the liquid inlet 3 to cool the heating component 2, and then flows out from the liquid outlet 5.
[0038] By designing a box body 1 with a cavity 11 and a box cover 12, a closed and controllable environment is provided for the heating component 2, thereby avoiding the open structure of the current charging module, which causes external impurities such as dust and salt spray to enter the module and potentially cause various circuit failures inside the module, reducing the maintenance frequency and extending the life cycle of the cold plate liquid-cooled charging module.
[0039] The interior of the hollow cold plate 7 is a cavity structure, allowing the coolant to flow therein, thereby taking away the heat of the heating component 2 through heat exchange: the coolant flows into the hollow cold plate 7 from the liquid inlet 3, absorbs heat when passing through the heating component 2, and then flows out from the liquid outlet 5, forming a cooling cycle, achieving a temperature balance between the heating components 2 and the heating components 2, and controlling the temperature difference to the lowest level as much as possible, greatly improving the balance and safety of the charging capacity of the entire cold plate liquid-cooled charging module.
[0040] like Figure 4 As shown, a cross-piece assembly 72 is provided inside the hollow cold plate 7, and the cross-piece assembly 72 is perpendicular to the bottom plate 71. The cross-piece assembly 72 forms a plurality of flow channels 723 inside the hollow cold plate 7. The coolant flows into the hollow cold plate 7 from the liquid inlet 3, flows through the plurality of flow channels 723, cools the heat generating component 2, and then flows out from the liquid outlet 5. The cross-piece assembly 72 is provided inside the hollow cold plate 7, and the interior of the cold plate is divided into a plurality of flow channels 723, which prolongs the residence time of the coolant in the hollow cold plate 7, increases the contact area between the coolant and the heat generating component 2, and improves the cooling efficiency.
[0041] The cross-piece assembly 72 includes a plurality of first cross-pieces 721 and a plurality of second cross-pieces 722. The longitudinal width of the first cross-piece 721 is wider than that of the second cross-piece 722. The first cross-piece 721 and the second cross-piece 722 are arranged in parallel with a gap therebetween. The plurality of first cross-pieces 721 and the plurality of second cross-pieces 722 are evenly arranged in the hollow cold plate 7. The different width designs of the first cross-pieces 721 and the second cross-pieces 722 help the coolant to form a more complex flow path inside the hollow cold plate 7, thereby further improving the cooling effect. In addition, a plurality of positioning holes 724 may be provided in the first cross-piece 721 having a larger longitudinal width. The positioning holes 724 penetrate through the bottom plate 71 and are connected to the bottom plate 71, thereby fixing the cross-piece assembly 72 in the hollow cold plate 7.
[0042] The transverse sheet component 72 has high designability, and the number and shape of the flow channel 723 can be flexibly designed, further increasing the contact area between the coolant and the heat generating component 2 and the complexity of the flow channel 723, for example Figure 4 As shown, the first transverse piece 721 and the second transverse piece 722 can be set to a rectangular sheet with a certain width, and three first transverse pieces 721 are evenly spaced, and two second transverse pieces 722 are evenly spaced between every two first transverse pieces 721. The coolant enters the hollow cold plate 7 from the liquid inlet 3, along the flow channel 723 formed by the first transverse piece 721 and the second side wall 712 of the box body 1, turns through the third side wall 713 or the fourth side wall 714 of the box body 1 and flows into the flow channel 723 formed by the first transverse piece 721 and the second transverse piece 722, flows through the flow channels 723 composed of the first transverse piece 721 and the second transverse piece 722 in turn, and finally flows out from the liquid outlet 5, which significantly improves the cooling efficiency of the hollow cold plate 7.
[0043] The hollow cold plate 7 includes a first side wall 711, a second side wall 712, a third side wall 713, and a fourth side wall 714 which are vertically fixedly connected to the four sides of the bottom plate 71; the first side wall 711 and the second side wall 712 are arranged in parallel to each other, and the third side wall 713 and the fourth side wall 714 are arranged in parallel to each other. A cover plate opposite to the bottom plate 71 is provided on the upper edges of the first side wall 711, the second side wall 712, the third side wall 713, and the fourth side wall 714, so as to increase the sealing performance of the hollow cold plate 7 and prevent the coolant from flowing out of the hollow cold plate 7.
[0044] like Figure 1 As shown, the first cooling liquid pipe 31 is detachably fixed on the liquid inlet 3, and the second cooling liquid pipe 51 is detachably fixed on the liquid outlet 5, which is convenient for installation, maintenance and replacement. The end of the first cooling liquid pipe 31 away from the liquid inlet 3 is detachably fixedly connected to the hollow cold plate 7, connecting the liquid inlet 3 and the hollow cold plate 7, for example Figure 2A first through hole 715 is provided on the first side wall 711 of the box body 1, and the first cold liquid pipe 31 is plugged into the first through hole 715; an end of the second cold liquid pipe 51 away from the liquid outlet 5 is detachably fixedly connected to the hollow cold plate 7, connecting the liquid outlet 5 and the hollow cold plate 7, for example Figure 2 A second through hole 716 is defined on the second side wall 712 , and the second cooling liquid pipe 51 is plugged into the second through hole 716 .
[0045] Appropriate pipe types and connection methods can be selected according to different application scenarios. For example, the first cold liquid pipe 31 and the second cold liquid pipe 51 adopt circular pipes, and the connection between the first cold liquid pipe 31 and the hollow cold plate 7 and the connection between the second cold liquid pipe 51 and the hollow cold plate 7 adopt plug-in or other detachable connection methods such as bolt and nut connection or pin connection, so as to realize flexible connection and disconnection between the first cold liquid pipe 31 and the second cold liquid pipe 51 and the hollow cold plate 7, so that when the first cold liquid pipe 31 and the second cold liquid pipe 51 need to be replaced or repaired, there is no need to disassemble the entire hollow cold plate 7 or the box 1, which greatly improves the convenience of maintenance.
[0046] like Figure 5 As shown, a closed cooling liquid circulation pipe 8 is detachably fixed outside the box 1, and one end of the cooling liquid circulation pipe 8 is connected to the liquid inlet 3, and the other end is connected to the liquid outlet 5; a radiator 81 is provided at one end of the cooling liquid circulation pipe 8 near the liquid outlet 5, and the cooling liquid circulates inside the hollow cold plate 7, flows out through the liquid outlet 5, and is cooled by the radiator 81 through an external cooling device such as a cooling fan, and is recycled again. A power device 82 such as an oil pump is provided at one end of the cooling liquid circulation pipe 8 near the liquid inlet 3 to drive the cooling liquid to circulate in the cooling liquid circulation pipe 8.
[0047] A first extension plate 717 is provided at the bottom of the third side wall 713, and the first extension plate 717 is detachably fixedly connected to the bottom plate 71. A second extension plate 718 is provided at the bottom of the fourth side wall 714, and the second extension plate 718 is detachably fixedly connected to the bottom plate 71. For example, the bottom plate 71 is connected to the first extension plate 717 by threads or buckles, and the bottom plate 71 is connected to the second extension plate 718 by threads or buckles, so that the connection between the hollow cold plate 7 and the box body 1 is more secure, reducing the risk of loosening or damage caused by vibration or other external forces, and enhancing the connection stability between the hollow cold plate 7 and the box body 1.
[0048] like Figure 1The bottom wall 13 of the box 1 is provided with heat dissipation holes 131, which are evenly distributed on the bottom wall 13 of the box 1, increasing the air flow inside the box 1, allowing external air to enter the cavity 11, and perform heat exchange with the heating component 2, which helps to dissipate heat, helps to reduce the temperature of the heating component 2, and further improves the heat dissipation effect. Through the heat exchange between the heat dissipation holes 131 and the external environment, the working environment of the heating component 2 is optimized and the service life of the heating component 2 is extended.
[0049] like Figure 1 The liquid inlet 3 is provided with a liquid inlet pipe 4, on which a liquid inlet quick-connection joint 41 is detachably fixedly connected, and the liquid outlet 5 is provided with a liquid outlet pipe 6, on which a liquid outlet quick-connection joint 61 is detachably fixedly connected, and both the liquid inlet quick-connection joint 41 and the liquid outlet quick-connection joint 61 are arranged in an "L" shape; a cylindrical mounting block 411 is arranged at a right angle to the liquid inlet quick-connection joint 41, and a mounting through hole 412 is opened on the cylindrical mounting block 411. The cylindrical mounting block 411 and the mounting through hole 412 opened thereon provide an additional fixing point for maintenance personnel, which is convenient for stably fixing and operating the joint during maintenance.
[0050] like Figure 3 Preferably, the side of the cylindrical mounting block 411 is provided with a first fixing plate 413 and a second fixing plate 414 respectively, the first fixing plate 413 and the second fixing plate 414 are perpendicular to each other and tangent to the same outer wall of the cylindrical mounting block 411, the first fixing plate 413 is embedded in a side close to the liquid inlet pipe 4 and is perpendicular thereto, and the second fixing plate 414 is embedded in a side away from the liquid inlet pipe 4 and is perpendicular thereto. The first fixing plate 413 and the second fixing plate 414 are designed to fit the cylindrical mounting block 411, so that the entire liquid inlet quick plug connector 41 is more structurally stable, the loosening or deformation caused by long-term use is reduced, the structural strength of the liquid inlet quick plug connector 41 is enhanced, the liquid inlet quick plug connector 41 is more stable when subjected to pressure, and the risk of damage caused by external forces is reduced, so that the cylindrical mounting block 411 not only provides an additional mounting point, but also enhances the overall strength of the liquid inlet quick plug connector 41 through its structure, making it more durable. The specific structure of the liquid outlet quick plug connector 61 is the same as that of the liquid inlet quick plug connector 41.
[0051] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
