The energy storage batteries placed on the liquid cold plates can easily bend the liquid cold plates below, especially the heat exchange tubes. The heat exchange tubes are bent and deformed, resulting in poor contact between the liquid cold plates and the energy storage batteries, thereby affecting the thermal management of the energy storage batteries.

In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0055] like Figure 1 As shown, the present application embodiment provides a tray 1 of a liquid cooling box, the tray 1 includes a main body 11 and at least one reinforcing rib 12. Along the thickness direction of the tray 1, the main body 11 has a mounting portion 111, the mounting portion 111 is used to mount an object to be mounted, and the object to be mounted may be a heat exchanger 2, etc. The reinforcing rib 12 is located in the mounting portion 111, and may be raised relative to the wall surface of the mounting portion 111, and is used to support the object to be mounted. Figure 2 As shown, the reinforcing rib 12 and / or the main body 11 is provided with a recessed portion 121 a , and the recessed portion 121 a is recessed in the thickness direction of the tray 1 .

[0056] The reinforcing rib 12 and / or the main body 11 are provided with a supporting portion 125 ; the tray further comprises a recessed portion 121 a , which is recessed in the thickness direction of the tray 1 , and has a preset height difference with the supporting portion 125 .

[0057] By providing the reinforcing rib 12 on the tray 1, the structural strength of the main body 11 can be enhanced to reduce the possibility of deformation of the main body 11. Moreover, the supporting portion 125 of the reinforcing rib 12 can be used to support the object to be installed, thereby improving the structural strength of the object to be installed and reducing the possibility of deformation of the object to be installed. In this embodiment, the recessed portion is provided on the left and right sides of the reinforcing rib 12. In other embodiments, it can be provided at the position of the reinforcing rib and / or the main body 11. The recessed portion can be a part of the structure of the reinforcing rib 12, or it can be a part of the main body that is separately provided, such as formed in the main body by sheet metal, or fixed to the main body by sheet metal parts, or an area enclosed by the reinforcing rib and the main body. The recessed portion 121a provided can be used to avoid the object to be installed located at the installation portion 111. The recessed portion 121a has a preset height difference with the supporting portion 125. The horizontal position of the recessed portion is lower than that of the supporting portion 125, thereby reducing the possibility of interference between the object to be installed and the reinforcing rib 12 and / or the main body 11, thereby facilitating the optimization of the structure of the tray 1 and more in line with actual use requirements.

[0058] In this embodiment, the tray 1 can be applied to a liquid cooling box, and a heat exchange component 2 such as a liquid cooling plate is arranged on the mounting portion 111 , and the battery and the like are located on a side of the liquid cooling plate away from the tray 1 .

[0059] By providing a reinforcing rib 12 on the tray 1, a support portion 125 is provided on the upper part of the reinforcing rib, and the support portion 125 can provide support for the heat exchanger 2 such as the liquid cooling plate, and the preset height difference between the recessed portion and the support portion 125 is roughly equal to the height difference between the heat exchanger header and the heat exchanger tube, thereby reducing the possibility of the battery bending the heat exchanger 2, causing the heat exchanger 2 to deform, and further reducing the gap between the heat exchanger 2 and the battery, affecting the contact between the heat exchanger 2 and the battery, and causing the possibility of reduced heat exchange efficiency. Therefore, by providing the reinforcing rib 12, not only the structural strength of the tray 1 can be improved, but also the stability of the contact between the heat exchanger 2 and the battery can be improved, thereby improving the heat exchange efficiency and being more in line with actual usage requirements.

[0060] like Figure 1 As shown, in this embodiment, the reinforcing rib 12 includes at least one first reinforcing rib 121 and at least one second reinforcing rib 122, the first reinforcing rib 121 extends along a first direction of the tray 1, and the second reinforcing rib 122 extends along a second direction of the tray, and there is an angle between the first direction and the second direction.

[0061] In this embodiment, the first direction may be the length direction of the tray 1 , the second direction may be the width direction of the tray 1 , and the first direction and the second direction may be perpendicular to each other.

[0062] By providing the first reinforcing ribs 121 and the second reinforcing ribs 122 , the tray 1 and the object to be installed can be supported in different directions, thereby facilitating the improvement of the structural strength of the tray 1 and reducing the possibility of deformation of the object to be installed located at the installation portion 111 .

[0063] like Figure 1 As shown, in this embodiment, the main body 11 can be provided with a plurality of first reinforcing ribs 121, and the number of the first reinforcing ribs 121 can be two, three, four or more, and the second reinforcing ribs 122 are located between adjacent first reinforcing ribs 121, and along the thickness direction of the pallet 1, the heights of the first reinforcing ribs 121 and the second reinforcing ribs 122 are the same.

[0064] By arranging the second reinforcing ribs 122 between adjacent first reinforcing ribs 121, the first reinforcing ribs 121 and the second reinforcing ribs 122 can be relatively evenly distributed, thereby facilitating the reinforcement effect of the first reinforcing ribs 121 and the second reinforcing ribs 122 on the main body 11. When the mounting portion 111 is installed with an object to be installed, the effect of the reinforcing ribs 12 on the object to be installed can also be enhanced.

[0065] The first reinforcing rib 121 may intersect with the second reinforcing rib 122, and the second reinforcing rib 122 may be inserted into the adjacent first reinforcing rib 121.

[0066] The first reinforcing ribs 121 and the second reinforcing ribs 122 may be distributed in a grid pattern so that the reinforcing ribs 12 can be relatively evenly distributed on the pallet 1 , thereby facilitating the reinforcement effect of the reinforcing ribs 12 on the pallet 1 , improving the structural strength of the pallet 1 , and reducing the possibility of deformation of the pallet 1 .

[0067] like Figure 1 As shown, in this embodiment, the first reinforcing rib 121 includes a first reinforcing portion 121b and a second reinforcing portion 121c, the width of the first reinforcing portion 121b is not less than the width of the second reinforcing portion 121c, and the first reinforcing portion 121b and the second reinforcing portion 121c are spaced apart.

[0068] In other embodiments, the width of the first reinforcing portion 121 b may be greater than the width of the second reinforcing portion 121 c .

[0069] The width of the first reinforcing portion 121b can be relatively large, and it can be used to support the object to be installed while reinforcing the structural strength of the tray 1. Since the first reinforcing portion 121b is relatively wide, it can be helpful to increase the contact area between the first reinforcing portion 121b and the object to be installed, thereby helping to improve the supporting effect of the first reinforcing portion 121b on the object to be installed. The second reinforcing portion 121c can be used to reinforce the main body 11, and the second reinforcing portion 121c can also be used to support the edge of the object to be installed.

[0070] In other embodiments, the second reinforcing portion 121c may be located at the edge of the tray 1, that is, the second reinforcing portion 121c is located outside the first reinforcing portion 121b, and is used to support the edge of the object to be installed and also to fix the object to be installed.

[0071] like Figure 2 As shown, in this embodiment, at least one end of the first reinforcing rib 121 is provided with a recessed portion 121a, and the recessed portion 121a can be used to form a mounting groove to mount the object to be mounted. The tray 1 can also include a bracket 13, at least part of the bracket 13 is located in the recessed portion 121a, and the bracket 13 is connected to the side wall of the recessed portion 121a.

[0072] The bracket 13 can be used to connect with the object to be installed, so as to improve the stability of the connection between the object to be installed and the tray 1 and better meet the actual use requirements.

[0073] like Figure 2 As shown, in this embodiment, along the extension direction of the first reinforcing rib 121, the recessed portion 121a passes through one end of the first reinforcing rib 121 close to the edge of the main body 11, and the bracket 13 can be "L"-shaped, and the bracket 13 is connected to at least two side walls of the recessed portion 121a.

[0074] Such a design facilitates positioning of the bracket 13 . Meanwhile, provision of the bracket 13 can help improve the stability of the connection between the object to be installed and the tray 1 , which is more in line with actual usage requirements.

[0075] like Figure 3 As shown, in this embodiment, the reinforcing ribs 12 can be arranged at intervals, such as Figure 4 As shown, the reinforcing rib 12 includes a body portion 123 and a connecting portion 124. The connecting portion 124 is located at opposite sides of the body portion 123. The body portion 123 is connected to the main body portion 11 through the connecting portion 124. Along the thickness direction of the tray 1, there is a gap between the body portion 123 and the main body portion 11.

[0076] In this embodiment, the cross section of the reinforcing rib 12 may be a “J”-shaped structure, and the top of the “J”-shaped structure is the supporting portion 125 .

[0077] Such a design can improve the structural strength of each reinforcing rib 12, thereby improving the reinforcing effect of the reinforcing rib 12 on the pallet 1, thereby improving the structural strength of the pallet 1. At the same time, such a design can also help improve the load-bearing capacity of the reinforcing rib 12, thereby improving the supporting capacity of the reinforcing rib 12 for the object to be installed, thereby reducing the possibility of deformation of the object to be installed under load, which is more in line with actual use requirements.

[0078] Based on the tray 1 of the liquid cooling box involved in the above embodiments, Figure 5 As shown, the embodiment of the present application also provides a liquid cooling box, such as Figure 6 As shown, the liquid cooling box includes a tray 1 and a heat exchanger 2, wherein the tray 1 can be the tray 1 involved in any of the above embodiments. That is, the tray 1 can include a main body 11 and at least one reinforcing rib 12, and the reinforcing rib 12 is arranged in the mounting portion 111 of the main body 11. The reinforcing rib 12 and / or the main body 11 are provided with a supporting portion 125, and the tray also includes a recessed portion (121a), and the recessed portion (121a) is recessed along the thickness direction of the tray (1); the recessed portion (121a) and the supporting portion 125 have a preset height difference; the heat exchanger 2 is located on the side of the tray 1 provided with the reinforcing rib 12, and along the height direction of the liquid cooling box, the heat exchanger 2 is in contact with the surface of the supporting portion 125 of the reinforcing rib 12. The heat exchanger includes a manifold 21, and at least a portion of the manifold 21 is located in the recessed portion 121a.

[0079] By designing the reinforcing ribs 12 on the tray 1, the structural strength of the tray 1 can be improved, and the heat exchanger 2 can also be used to lift and support it, thereby reducing the possibility of compression and deformation of the heat exchanger 2. The recessed portion 121a is used to avoid the manifold 21 of the heat exchanger 2 to reduce the possibility of interference between the heat exchanger 2 and the tray 1, thereby improving the stability of the installation of the heat exchanger 2 and better meeting the actual use requirements.

[0080] like Figure 5 As shown, in this embodiment, the liquid cooling box may include a shell 3, which may be connected to the tray 1 and is used to enclose a relatively closed cavity with the tray 1 to install the heat exchange component 2 and the battery, etc.

[0081] like Figure 7 As shown, in this embodiment, the heat exchange element 2 includes a header 21 and at least one flow section 24. Figure 8 and Fig. 9 As shown, the manifold 21 at least includes a first manifold 211, a second manifold 212, and a third manifold 213. The second manifold 212 and the third manifold 213 are located on opposite sides of the flow section 24, and the first manifold 211 and the second manifold 212 are located on the same side of the flow section 24. One end of the first manifold 211 has a first flow opening 211a, and the other end is connected to the second manifold 212. The third manifold 213 has a second flow opening 213a, and the flow section 24 is connected to the second manifold 212 and the third manifold 213.

[0082] The reinforcing ribs 12 and / or the recessed portions 121a provided on the main body can be formed to form a groove for installing the manifold 21. When the heat exchanger 2 is installed on the tray 1, one side of the heat exchanger 2 is in contact with the first reinforcing ribs 121 and the second reinforcing ribs 122, so that the heat exchanger 2 is supported by the first reinforcing ribs 121 and the second reinforcing ribs 122, which can reduce the possibility of the heat exchanger 2 being compressed and deformed, thereby facilitating the maintenance of the flatness of the heat exchanger 2, improving the stability of the contact between the heat exchanger 2 and the battery, and thus improving the heat exchange efficiency.

[0083] The heat exchange medium of the heat exchange element 2 can enter the first header 211 along the first flow port 211a, flow along the first header 211 to the second header 212, pass through the heat exchange section, flow between the second header 212 and the third header 213, and then flow out of the heat exchange element 2 along the third header 213. This design facilitates the heat exchange medium to flow in the heat exchange element 2, thereby performing heat exchange.

[0084] like Fig.10 As shown, in this embodiment, the heat exchanger 2 at least includes a first heat exchange portion 22 and a second heat exchange portion 23, the first heat exchange portion 22 and the second heat exchange portion 23 are connected through a header 21, and the first heat exchange portion 22 and the second heat exchange portion 23 each include at least one flow section 24. The reinforcing rib 12 includes a first reinforcing rib 121 and a second reinforcing rib 122, the first reinforcing rib 121 includes a first reinforcing portion 121b and a second reinforcing portion 121c, along the height direction of the liquid cooling box, the projection of the first reinforcing portion 121b is located within the projection range of the flow section 24 of the first heat exchange portion 22 or the flow section 24 of the second heat exchange portion 23, and a portion of the projection of the second reinforcing portion 121c is located within the projection range of the flow section 24 of the first heat exchange portion 22, and the other portion is located within the projection range of the flow section 24 of the second heat exchange portion 23. The first reinforcing portion 121b, the second reinforcing portion 121c, the first heat exchange portion 22, and the second heat exchange portion 23 all extend along the first direction of the tray 1.

[0085] The heat exchanger 2 can be composed of at least two heat exchange parts spliced ​​together. Such a design can help reduce the volume of a single heat exchange part. Compared with an integral heat exchanger 2, the assembly design can reduce the manufacturing difficulty caused by the large overall volume of the heat exchanger 2, which is conducive to improving the product qualification rate and more in line with actual production needs. Moreover, the assembly design can make the overall structure of the heat exchanger 2 more flexible, and it can be spliced ​​according to actual needs, so as to adjust the volume of the heat exchanger 2, and then make the heat exchanger 2 suitable for pallets 1 and liquid cooling boxes of different sizes, which is conducive to reducing costs. The first reinforcement part 121b is used to support the heat exchange part, and the second reinforcement part 121c can support the splicing position of the heat exchange part, which is conducive to improving the supporting effect of the reinforcement rib 12 on the heat exchange part, reducing the possibility of the heat exchange part being compressed and deformed, thereby helping to improve the stability of the contact between the heat exchange part and the object to be heat exchanged, improve the heat exchange efficiency, and better meet the actual use needs. The reinforcing part and the heat exchange part extend in the same direction, so that the reinforcing part can support the heat exchange part, especially the second reinforcing part 121c supports the joint position of the first heat exchange part 22 and the second heat exchange part 23 .

[0086] like Figure 7 As shown, in this embodiment, the heat exchange element 2 can be spliced ​​by two heat exchange parts, the first part includes two microchannel flat tubes, the second part includes three microchannel flat tubes, and the heat exchange medium flows in the direction shown by the arrow in the figure.

[0087] like Figure 7 As shown, in this embodiment, the first flow opening 211a and the second flow opening 213a are located on the same side of the liquid cooling box, and one end of the first header 211 having the first flow opening 211a is bent toward a side close to the third header 213, and / or one end of the third header 213 having the second flow opening 213a is bent toward a side close to the first header 211. At the same time, a protection design is provided for the bending positions of the first flow opening 211a and the second flow opening 213a.

[0088] By placing the first manifold 211 and the second manifold 212 on the same side of the flow section 24, and the second manifold 212 and the third manifold 213 on different sides of the flow section 24, the first flow opening 211a and the second flow opening 213a can be located on the same side of the heat exchanger 2, thereby facilitating the installation and maintenance of the heat exchanger 2, improving the distribution performance and heat exchange capacity, and better meeting the actual use requirements. The first flow opening 211a and the second flow opening 213a are bent to facilitate the installation of the heat exchanger 2 in the liquid cooling box, reducing the possibility of the first flow opening 211a and / or the second flow opening 213a interfering with other structures.

[0089] In this embodiment, along the thickness direction of the heat exchanger 2, the first header 211 is located above the second header 212. A partition is provided between the second header 212 and the third header 213.

[0090] The embodiment of the present application provides a tray 1 of a liquid cooling box and a liquid cooling box, wherein the tray 1 includes a main body 11 and at least one reinforcing rib 12, the reinforcing rib 12 is arranged in a mounting portion 111 of the main body 11, and is raised relative to the surface of the main body 11, and the reinforcing rib 12 and / or the main body 11 are provided with a recessed portion 121a recessed along the thickness direction of the tray 1. By providing the reinforcing rib 12, the structure of the tray 1 can be strengthened, and the structural strength of the tray 1 can be improved. At the same time, the reinforcing rib 12 can also support the object to be installed located at the mounting portion 111, and reduce the possibility of deformation of the object to be installed.
