[0053] As Figure 1 shown, the embodiments of this application provide a tray 1 for a liquid cooling box. The tray 1 may include a first main body portion 11 and a second main body portion 12. The second main body portion 12 is disposed along the circumferential direction of the first main body portion 11. The first main body portion 11 and the second main body portion 12 are integrally formed. The second main body portion 12 includes a first frame 121 and a second frame 122. Along the first direction of the tray 1, the first frame 121 is located on opposite sides of the first main body portion 11. Along the second direction of the tray 1, the second frame 122 is located on opposite sides of the first main body portion 11. The first main body portion 11 has a receiving cavity 18. The first frame 121, the second frame 122 and the first main body portion 11 are configured to be at least part of the boundary of the receiving cavity 18. Along the thickness direction of the tray 1, the heights of the first frame 121 and the second frame 122 are the same.

[0054] In the solution provided by the embodiment of the present application, by providing the first frame 121 and the second frame 122, they can cooperate with the first main body 11 to enclose a receiving cavity 18 for installing an object to be installed. The first frame 121 and the second frame 122 are arranged along the circumferential direction of the first main body 11 to form a structure similar to a flanging, which is used to protect the object to be installed located in the receiving cavity 18 along the circumferential direction. The integral molding of the first main body 11 and the second main body 12 is beneficial to improving the integrity of the tray 1. Moreover, the same height of the first frame 121 and the second frame 122 is convenient for installing components such as gaskets. Compared with the assembled liquid cooling box chassis, the solution provided by the embodiment of the present application is beneficial to improving the sealing performance of the tray 1 when applied to the liquid cooling box, improving the performance of the liquid cooling box, and better meeting the actual use requirements.

[0055] As Figure 2 、 Figure 3 and Figure 4 shown, in the embodiment of the present application, the first frame 121 includes a first body portion 121a and a second body portion 121b. The first body portion 121a is connected to the first main body 11 and has an included angle with the first main body 11. The second body portion 121b is located at one end of the first body portion 121a away from the first main body 11 and bends towards the direction close to the receiving cavity 18.

[0056] Through such a design, the first frame 121 can form a multi-segment flanging structure. The second body portion 121b is used to be arranged at the edge position of the first main body 11 to protect the object to be installed in the receiving cavity 18. The second body portion 121b can be used to increase the area of the first frame 121 along the first direction, so as to facilitate the setting of gaskets, etc., which is beneficial to increasing the contact area between the first frame 121 and the seal 4 and improving the sealing effect.

[0057] In this embodiment, the first direction and the second direction can be perpendicular to each other, and the dimension of the tray 1 along the first direction is greater than the dimension of the tray 1 along the second direction. That is, the first direction can be parallel to the length direction of the tray 1, and the second direction can be parallel to the width direction of the tray 1.

[0058] As Figure 5 shown, in this embodiment, at least a part of the second frame 122 bends along the direction away from the receiving cavity 18, and the adjacent first frame 121 and second frame 122 are fixedly connected.

[0059] The way of fixed connection can be welding, and the joint of the first frame 121 and the second frame 122 can be fully welded and polished flat.

[0060] During welding, laser welding or other methods can be used for seam welding and grinding, thereby improving the integrity of the tray 1, which is beneficial to enhancing the overall sealing performance of the tray 1 and better meeting the actual usage requirements. In other embodiments, other means can be used to fix the first frame and the second frame to achieve the sealing effect.

[0061] As Figure 5 shown, in this embodiment, the tray 1 may further include a roller device 13. The second frame 122 may include a third body portion 122a, a fourth body portion 122b, and a fifth body portion 122c. The third body portion 122a is connected to the first main body portion 11, the fourth body portion 122b is connected to the third main body portion and bends away from the accommodating cavity 18. The fifth body portion 122c is connected to one end of the fourth body portion 122b away from the third body portion 122a. The third body portion 122a, the fourth body portion 122b, and the fifth body portion 122c are used to enclose an installation groove 14, and the roller device 13 is installed in the installation groove 14.

[0062] At least a part of the second main body portion 12 bends away from the accommodating cavity 18 to form the installation groove 14 for installing the roller device 13. By installing the roller device 13 on the tray 1, when placing the tray 1 or the liquid cooling box with the tray 1 in a position such as an energy storage cabinet, the roller device 13 can cooperate with the guide rail to facilitate installation and disassembly.

[0063] In this embodiment, the tray 1 includes at least two roller devices 13. The rollers are located on opposite sides of the first main body portion 11 along the second direction, and the roller devices 13 on the same side are arranged along the first direction.

[0064] By arranging the roller devices 13 on both sides of the first main body portion 11, the stability of the tray 1 during movement can be improved. A plurality of roller devices 13 can be arranged on the same side of the first main body portion 11, and the number of roller devices 13 on one side can be one, two, three, or more. This can further improve the convenience of installation and disassembly and the stability of the tray 1 during movement.

[0065] As Figure 5 shown, in this embodiment, the roller device 13 includes a rolling member 131, a mounting member 132, and a bracket 133. The rolling member 131 is installed on the bracket 133 through the mounting member 132, and the bracket 133 is installed on the side wall of the installation groove 14.

[0066] Through such a design, the rolling member 313, the mounting member 132, and the bracket 133 can be pre-combined to make the roller device 13 modular. During installation, it is only necessary to fixedly connect the bracket 133 to the side wall of the installation groove 14. The operation is relatively simple and is beneficial to improving the installation efficiency.

[0067] During installation, the roller device 13 as a whole can be installed on the tray 1 through connecting parts such as bolts. The roller device 13 can not only facilitate the installation and disassembly of the tray 1 from the liquid cooling box, but also be used to bear the load.

[0068] Based on the tray 1 of the liquid cooling box provided by the above embodiments, as Figure 6 shown, the embodiment of the present application also provides a liquid cooling box, which includes a housing 2, a tray 1 and a heat exchange member 3. The tray 1 can be the tray 1 involved in any of the above embodiments, that is, the tray 1 can include an integrally formed first main body portion 11 and a second main body portion 12. The second main body portion 12 includes a first frame 121 and a second frame 122. Along the first direction of the tray 1, the first frame 121 is located on opposite sides of the first main body portion 11, and the second frame 122 is located on opposite sides of the first main body portion 11 along the second direction of the tray 1 and is configured with the first main body portion 11 as at least part of the boundary of the accommodating cavity 18. The heat exchange member 3 is located in the accommodating cavity 18 of the tray 1. The housing 2 has a flange, and the flange cooperates with the second main body portion 12, as Figure 7 and Figure 8 shown. There is a sealing member 4 such as a gasket between the housing 2 and the tray 1, and the sealing member 4 abuts against one side of the first frame 121 and the second frame 122 facing the housing 2. The housing 2 can be used for the connection and fixation of electrical connectors and at the same time for protecting batteries and the like located inside the liquid cooling box. The housing 2 and the tray 1 can be connected through connecting parts such as bolts to form a relatively airtight cavity.

[0069] During processing, the tray 1 can be processed from a whole steel plate, cut by laser, and numerically controlled to form a hem, so as to form a tray 1 with a frame. Compared with the spliced chassis, the integrity and sealing performance of the tray 1 of the liquid cooling box provided by the embodiment of the present application are better. Setting the sealing member 4 between the tray 1 and the housing 2 can help improve the sealing performance of the liquid cooling box, which more meets the actual use requirements.

[0070] Compared with the all-aluminum alloy chassis, using a steel tray 1 can reduce the processes of welding and applying sealant between the aluminum alloy frame and the heat exchange member 3, which is beneficial to improving the assembly efficiency of the product and reducing the product cost.

[0071] As Figure 7 shown, in this embodiment, the tray 1 includes a first connection assembly 15, and the first connection assembly 15 is connected to the first frame 121.

[0072] The first connection component 15 can be used to protect the manifold of the heat exchanger 3 and can also be used to fixedly connect to the battery pack installed in the liquid cooling box, facilitating the positioning of the battery pack, improving the relative position accuracy between the battery pack and the heat exchanger 3, reducing the possibility of displacement of the battery pack. At the same time, the first connection component 15 can also strengthen the tray 1, which is beneficial to improving the overall structural strength of the tray 1 and better meeting the actual usage requirements.

[0073] As Figure 3 shown, in this embodiment, the first connection component 15 includes a first connecting piece 151 and a second connecting piece 152. The first connecting piece 151 and the second connecting piece 152 are connected, and the first connecting piece 151 is connected to the second main body part 12, and the second connecting piece 152 is connected to the first main body part 11. As Figure 4 shown, the tray 1 may further include a second connection component 16, and the second connection component 16 is connected to the first frame 121.

[0074] Through such a design, it is convenient for the first connection component 15 to be connected to the first main body part 11 and the second main body part 12, which is beneficial to improving the strengthening effect of the first connection component 15 on the tray 1, and further beneficial to improving the overall structural strength of the tray 1. The second connection component 16 can be used to protect the manifold of the heat exchanger 3 and can also be used to fixedly connect to the battery pack installed in the liquid cooling box, facilitating the positioning of the battery pack, improving the relative position accuracy between the battery pack and the heat exchanger 3, reducing the possibility of displacement of the battery pack. At the same time, the first connection component 15 can also strengthen the tray 1, which is beneficial to improving the overall structural strength of the tray 1, enhancing the load-bearing and bending resistance of the tray 1, and better meeting the actual usage requirements.

[0075] The first frame 121 can be bent toward the side close to the accommodation cavity 18 for connection with the first connection component 15, and the second frame 122 can be bent toward the side away from the accommodation cavity 18 for forming the installation groove 14 of the roller device 13.

[0076] As Figure 9 shown, in this embodiment, the tray 1 includes an installation part 17. The first connection component 15, the second connection component 16, the first frame 121, and the second frame 122 are used to enclose an installation space. The installation part 17 is located in the installation space. At least part of the heat exchanger 3 is located in the installation part 17, and the installation part 17 is arranged along the circumference of the heat exchanger 3.

[0077] The installation part 17 can be used to enhance the overall structural strength of the tray 1, thereby reducing the possibility of deformation of the tray 1. Moreover, through such a design, it is convenient to install the heat exchange component 3, which is beneficial to improving the installation position accuracy of the heat exchange component 3, enhancing the contact stability between the heat exchange component 3 and the battery assembly, and thus conducive to improving the heat exchange efficiency, which better meets the actual usage requirements.

[0078] An embodiment of the present application provides a tray 1 of a liquid cooling box and a liquid cooling box. The tray 1 includes a first main body part 11 and a second main body part 12 formed integrally. The second main body part 12 includes a first frame 121 and a second frame 122. Along the first direction of the tray 1, the first frame 121 is located on opposite sides of the first main body part 11. The second frame 122 is located on opposite sides of the first main body part 11 along the second direction of the tray 1 and is configured to form at least part of the boundary of the accommodating cavity 18 with the first main body part 11. Through such a design, it is beneficial to improve the sealing performance of the tray 1 and the liquid cooling box, and further beneficial to improving the heat exchange efficiency of the liquid cooling box, which better meets the actual usage requirements.
