Description

Technical Field

[0001] The present disclosure relates to the technical field of energy storage radiators, and in particular to a protective plate device of a liquid cooling plate and a liquid cooling plate. Background Art

[0002] Energy storage devices generate heat during use, so liquid cooling plates are usually required to dissipate heat to ensure the safety of the energy storage device. For example, when used in battery energy storage devices for new energy vehicles, the automotive liquid cooling plate needs to bear the weight of a large battery module, and at the same time, it cannot unilaterally increase the thickness of the liquid cooling plate to enhance its structural strength, thereby improving or increasing the load-bearing effect of the liquid cooling plate. Therefore, higher requirements are placed on the load-bearing effect of the liquid cooling plate.

[0003] In order to improve the load-bearing effect of the liquid cooling plate while taking into account the lightweight design requirements of the liquid cooling plate, as shown in Chinese patent document CN 219393522U, a liquid cooling plate and a battery pack are disclosed, including a cold plate body and a guard plate, wherein a flow channel is arranged on the cold plate body, and the guard plate is arranged at the bottom of the cold plate body. A convex strip for supporting the flow channel area on the cold plate body is arranged on the side of the guard plate facing the bottom of the cold plate body, and the length direction of the convex strip intersects with the flow channel direction located above it. The convex strip can cross the flow channel along the width direction of the flow channel at the bottom of the cold plate body, and support different areas of the flow channel in the width direction of the flow channel at the same time, which can reduce the deformation of the cold plate body, increase the structural strength of the cold plate body, and improve the overall strength and load-bearing performance of the liquid cooling plate. At the same time, the density of the convex strip arrangement can be reduced, and the area on the guard plate that can be used for weight-reducing hollowing design is larger, and the weight of the guard plate can be made lighter, which is conducive to the lightweight structural design of the liquid cooling plate, and the overall weight is controlled while achieving the improvement of strength and load-bearing performance.

[0004] However, the technical solution of the liquid cooling plate disclosed above still has the following problems: the guard plate of the technical solution is an integrally formed stamped structural part. Although the guard plate of the integrally formed stamped structural part has a certain structural strength, the guard plate is a thin sheet structure along the direction in which the first protrusion is evenly distributed (i.e., the length direction of the liquid cooling plate), that is, there is no load-bearing beam along the length direction of the liquid cooling plate. For example, when a group of battery modules needs to be added to the liquid cooling plate, the liquid cooling plate needs to be extended and lengthened, and the guard plate also needs to be extended and lengthened synchronously, so it is easy to cause the peripheral structure of the entire guard plate to bend and deform, and multiple convex strips in the middle of the guard plate to bend and collapse, thereby causing the structural strength of the guard plate to decrease, and then the load-bearing effect of the liquid cooling plate to deteriorate.

[0037] See also Figures 1 to 5 In order to better understand the protective plate device 10 of a liquid cooling plate disclosed in the present invention, the protective plate device 10 of a liquid cooling plate is further explained below:

[0038] A guard plate device 10 of a liquid cooling plate in one embodiment includes a liquid cooling plate 100, a longitudinal guard plate group 200 and a transverse guard plate group 300. The top surface of the liquid cooling plate 100 is used to support a battery module. The longitudinal guard plate group 200 is arranged at intervals along the bottom of the liquid cooling plate 100. The transverse guard plate group 300 includes a first square tube structure guard plate member 310 and a second square tube structure guard plate member 320; the first square tube structure guard plate member 310 is arranged on one side of the bottom of the liquid cooling plate 100 and is fixedly connected to the liquid cooling plate 100, and the second square tube structure guard plate member 320 is arranged on the other side of the bottom of the liquid cooling plate 100 and is fixedly connected to the liquid cooling plate 100; one end of the longitudinal guard plate group 200 is fixedly connected to the first square tube structure guard plate member 310, and the other end of the longitudinal guard plate group 200 is fixedly connected to the second square tube structure guard plate member 320, and there is a first angle between the extension direction of the longitudinal guard plate group 200 and the extension direction of the first square tube structure guard plate member 310, and there is a second angle between the extension direction of the longitudinal guard plate group 200 and the extension direction of the second square tube structure guard plate member 320.

[0039] In this embodiment, the first square through-structure guard plate 310 is arranged on one side of the bottom of the liquid cooling plate 100 and is fixedly connected to the liquid cooling plate 100, and the second square through-structure guard plate 320 is arranged on the other side of the bottom of the liquid cooling plate 100 and is fixedly connected to the liquid cooling plate 100, so that the structural strength of the liquid cooling plate 100 in the extending direction of the first square through-structure guard plate 310 and the second square through-structure guard plate 320 is effectively improved; at the same time, the longitudinal guard plate group 200 is arranged at intervals along the bottom of the liquid cooling plate 100 , a structural layout is adopted in which a first angle exists between the extension direction of the longitudinal guard plate group 200 and the extension direction of the first square-through structure guard plate component 310, and a second angle exists between the extension direction of the longitudinal guard plate group 200 and the extension direction of the second square-through structure guard plate component 320, thereby enhancing the structural connection stability of the guard plate device 10 of the liquid cooling plate, replacing the guard plate of the one-piece stamped structure component, and effectively improving the structural strength of the guard plate device 10 of the liquid cooling plate, so that the liquid cooling plate 100 has a good load-bearing effect.

[0040] like Figure 1 As shown, in one embodiment, the liquid cooling plate 100 includes an upper plate 110 and a lower flow channel plate 120, and the bottom surface of the upper plate 110 and the top surface of the lower flow channel plate 120 together form a flow channel cavity 101. The top surface of the upper plate 110 is provided with a first limit group 1110 and a second limit group 1120, the first limit group 1110 forms the battery module placement area 1101, and the second limit group 1120 forms the battery module placement area 1102, and the battery module placement area 1101 and the battery module placement area 1102 are respectively used to place the battery modules.

[0041] like Figure 1 As shown, in one embodiment, the upper plate 110 is provided with a liquid inlet 1103 and a liquid outlet 1104, and the flow channel cavity 101 is respectively connected with the liquid inlet 1103 and the liquid outlet 1104. It can be understood that the cooling medium of the cooling system of the new energy vehicle flows into the flow channel cavity 101 from the liquid inlet 1103, and flows back to the cooling system from the liquid outlet 1104 after sufficient heat exchange with the upper plate 110, so as to reliably dissipate heat and cool down the multiple battery modules on the battery module placement area 1 1101 and the battery module placement area 2 1102. In one embodiment, the liquid cooling plate 100 further includes a liquid inlet nozzle 130 and a liquid outlet nozzle 140; one end of the liquid inlet nozzle 130 is arranged at the liquid inlet 1103, so that the liquid inlet nozzle 130 is connected to the flow channel cavity 101, and the other end of the liquid inlet nozzle 130 is connected to the liquid supply end of the cooling system; one end of the liquid outlet nozzle 140 is arranged at the liquid outlet 1104, so that the liquid outlet nozzle 140 is connected to the flow channel cavity 101, and the other end of the liquid inlet nozzle 130 is connected to the liquid return end of the cooling system. It can be understood that the liquid inlet nozzle 130 and the liquid outlet nozzle 140 are used to make the cooling system and the flow channel cavity 101 have better connection effect and convenient connection.

[0042] like Figure 1 and Figure 2As shown, in one embodiment, the longitudinal guard plate group 200 includes a head end connecting guard plate 210, an intermediate connecting guard plate 220 and a tail end connecting guard plate 230; one end of the head end connecting guard plate 210, one end of the intermediate connecting guard plate 220 and one end of the tail end connecting guard plate 230 are respectively fixedly connected to the first square tube structure guard plate member 310, the other end of the head end connecting guard plate 210, the other end of the intermediate connecting guard plate 220 and the other end of the tail end connecting guard plate 230 are respectively fixedly connected to the second square tube structure guard plate member 320, and the head end connecting guard plate 210, the intermediate connecting guard plate 220 and the tail end connecting guard plate 230 are respectively staggered with the first square tube structure guard plate member 310 and the second square tube structure guard plate member 320. It can be understood that in other embodiments, the connection between the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 and the first square tube structure guard plate member 310 and the second square tube structure guard plate member 320 can be fixedly connected by ordinary welding, brazing or laser welding. In this embodiment, the connection between the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 and the first square tube structure guard plate member 310 and the second square tube structure guard plate member 320 is laser welding. Since laser welding has the characteristics of high convenience in operation and good connection stability at the welding point, the use of laser welding can ensure the overall structural connection stability of the guard plate device 10 of the liquid cooling plate, thereby effectively improving the structural strength of the guard plate device 10 of the liquid cooling plate.

[0043] like Figure 1 and Figure 5As shown, in one embodiment, the first end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 are all formed with a first protrusion 240a, and the first protrusion 240a abuts against the bottom surface of the lower flow channel plate 120. In one embodiment, the transverse guard plate group 300 also includes a middle reinforcing plate 330, and the middle reinforcing plate 330 is installed and fixed to the bottom surfaces of the first end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230. It can be understood that the number of the first protrusions 240a can be multiple, that is, the number of the first protrusions 240a can be reasonably set according to the actual shape requirements of the bottom surface of the lower flow channel plate 120; specifically, the first protrusion 240a is an integrated molding structure, and the stamping processing convenience and reliability are high. At the same time, the first protrusion 240a abuts against the bottom surface of the lower flow channel plate 120, so that the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 have better structural strength support. Among them, the middle reinforcing plate 330 is installed and fixed on the bottom surfaces of the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230, ensuring that as the number of battery modules on the liquid cooling plate 100 increases, the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 still have good structural stability, thereby effectively improving the structural strength of the guard plate device 10 of the liquid cooling plate, thereby enabling the liquid cooling plate 100 to withstand more weight of battery modules without affecting the heat dissipation performance of the liquid cooling plate 100.

[0044] It should be noted that the first protrusion 240a abuts against the bottom surface of the lower flow channel plate 120 to fix the lower flow channel plate 120 to the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 respectively by laser welding, and at the same time, the gap in the laser welding area (such as Figure 5 Elastic structural glue is filled around the front end connecting guard plate 210, the middle connecting guard plate 220 and the rear end connecting guard plate 230 to provide elastic buffering when bearing the gravity of the liquid cooling plate 100.

[0045] like Figures 1 to 4 As shown, in one embodiment, the guard plate device 10 of the liquid cooling plate also includes a fastening reinforcement plate 400 and a fastening reinforcement plate 500, the fastening reinforcement plate 400 is arranged below the connection between one end of the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 and the first square tube structure guard plate component 310 respectively; the fastening reinforcement plate 2500 is arranged below the connection between the other end of the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 and the second square tube structure guard plate component 320 respectively.

[0046] It can be understood that in this embodiment, by providing a fastening reinforcement plate 400 and a fastening reinforcement plate 2 500, the structural connection stability of the connection between the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 and the first square tube structure guard plate component 310 and the second square tube structure guard plate component 320 is further enhanced. Specifically, the fastening reinforcement plate 400 is laser welded to one end of the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 respectively; the fastening reinforcement plate 2 500 is laser welded to the other end of the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 respectively, thereby effectively improving the structural connection stability of the guard plate device 10 of the liquid cooling plate, thereby ensuring that the guard plate device 10 of the liquid cooling plate has good structural strength.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the first square tube structure guard plate 310 and the second square tube structure guard plate 320 are both hollow. It can be understood that the hollow setting can effectively ensure that the first square tube structure guard plate 310 and the second square tube structure guard plate 320 have good structural strength, and at the same time can also reduce the weight of the first square tube structure guard plate 310 and the second square tube structure guard plate 320, so that the first square tube structure guard plate 310 and the second square tube structure guard plate 320 are more lightweight and more practical.

[0048] like Figures 1 to 3 As shown, in one embodiment, the first angle is equal to the second angle; the angle of the first angle is 60° to 90°. It can be understood that the first angle and the second angle ensure that the extension direction of the longitudinal guard plate assembly 200 and the extension direction of the first square through structure guard plate member 310 and the extension direction of the second square through structure guard plate member 320 are staggered, so that the head end connecting guard plate 210, the middle connecting guard plate 220 and the tail end connecting guard plate 230 can provide strong support for the liquid cooling plate 100, ensuring the load-bearing effect of the liquid cooling plate 100.

[0049] The present disclosure also provides a liquid cooling plate, comprising the protective plate device of the liquid cooling plate described in any one of the above embodiments.

[0050] In this embodiment, by arranging the first square tube structure guard plate member on one side of the bottom of the liquid cooling plate and fixedly connected to the liquid cooling plate, and arranging the second square tube structure guard plate member on the other side of the bottom of the liquid cooling plate and fixedly connected to the liquid cooling plate, the structural strength of the liquid cooling plate in the extension direction of the first square tube structure guard plate member and the second square tube structure guard plate member is effectively improved; at the same time, the longitudinal guard plate group is also arranged at transverse intervals along the bottom of the liquid cooling plate, so that there is a first angle between the extension direction of the longitudinal guard plate group and the extension direction of the first square tube structure guard plate member, and there is a second angle between the extension direction of the longitudinal guard plate group and the extension direction of the second square tube structure guard plate member, thereby enhancing the structural connection stability of the guard plate device of the liquid cooling plate, replacing the guard plate of the one-piece stamped structure member, and then effectively improving the structural strength of the guard plate device of the liquid cooling plate, so that the liquid cooling plate has a good load-bearing effect.

[0051] Compared with the prior art, the present invention has at least the following advantages:

[0052] By arranging the first square tube structure guard plate on one side of the bottom of the liquid cooling plate and fixedly connected to the liquid cooling plate, and arranging the second square tube structure guard plate on the other side of the bottom of the liquid cooling plate and fixedly connected to the liquid cooling plate, the structural strength of the liquid cooling plate in the extension direction of the first square tube structure guard plate and the second square tube structure guard plate is effectively improved; at the same time, the longitudinal guard plate group is also arranged at transverse intervals along the bottom of the liquid cooling plate, so that there is a first angle between the extension direction of the longitudinal guard plate group and the extension direction of the first square tube structure guard plate, and there is a second angle between the extension direction of the longitudinal guard plate group and the extension direction of the second square tube structure guard plate, thereby enhancing the structural connection stability of the guard plate device of the liquid cooling plate, replacing the guard plate of the one-piece stamped structure, and then effectively improving the structural strength of the guard plate device of the liquid cooling plate, so that the liquid cooling plate has a good load-bearing effect.

[0053] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
