The components and arrangements described in the following specific examples are only used to simplify the present application and are only used as examples, not to limit the present application.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, 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 part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents the selected embodiments of the present application.

[0042] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] In the present application, unless otherwise clearly specified and limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, a first feature being above, above, and above a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below a second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0044] In the prior art, a curved cooling channel is usually provided inside the liquid cooling plate, and coolant is injected into the cooling channel to cool items located above the liquid cooling plate. However, the liquid cooling plate is small in size, has a small force-bearing area, and has a limited load-bearing capacity per unit area. It is easy to bend, and the cooling effect is not obvious. For example, although a support is provided under the liquid cooling plate in the prior art, the support strength of the support is insufficient, and the area where the support and the liquid cooling plate are attached is large, so that the cooling effect of the liquid cooling plate does not meet expectations.

[0045] In view of this, the purpose of the present invention is to provide a liquid cooling plate assembly and an energy storage device to solve the above technical problems existing in the prior art, which mainly include the following contents:

[0046] The first aspect of the present application provides a liquid cooling plate assembly, such as Figure 1-Figure 13 As shown, it includes: a liquid cooling plate 10 and a first support member 20, the liquid cooling plate 10 is located above the first support member 20, and the liquid cooling plate 10 is fixedly connected to the first support member 20. Exemplarily, the upper part of the liquid cooling plate 10 is usually used to place items that need to be cooled, such as a battery pack, and the first support member 20 is arranged below the liquid cooling plate 10. The liquid cooling plate and the first support member 20 are connected by nuts, welding, bonding, etc., to assist the liquid cooling plate 10 in supporting the battery pack to avoid excessive weight of the battery pack and damage to the liquid cooling plate.

[0047] The first support member 20 includes a frame structure 30 and a reinforcement structure 40;

[0048] The reinforcement structure 40 includes a transverse reinforcement member 41 and a longitudinal reinforcement member 42. The transverse reinforcement member 41 is a plate-shaped reinforcement rib, and the longitudinal reinforcement member 42 is a rod-shaped reinforcement rib. The number of transverse reinforcement members 41 is at least two, and the number of longitudinal reinforcement members 42 is at least two. The length direction of the liquid cooling plate 10 is the x direction, and the width direction is the y direction. The transverse reinforcement members 41 are spaced along the length of the liquid cooling plate 10; a plurality of longitudinal reinforcement members 42 are spaced between two adjacent transverse reinforcement members 41, and the longitudinal reinforcement members 42 are vertically connected to the transverse reinforcement members 41. The two ends of the longitudinal reinforcement members 42 are fixedly connected to the corresponding transverse reinforcement members 41 respectively, and the longitudinal reinforcement members 42 do not pass through the transverse reinforcement members 41, which reduces the influence on the support strength of the transverse reinforcement members 41. On the one hand, it reduces the damage to the structural integrity of the transverse reinforcement members, and on the other hand, it ensures the support strength of the transverse reinforcement members 41.

[0049] The frame structure 30 has a reinforcement cavity 31, and the reinforcement structure 40 is arranged in the reinforcement cavity 31. The frame structure 30 is a frame structure, including a first frame 34, a second frame 35, and a third frame 36. One end of the second frame 35 is connected to the end of the first frame 34, and the other end of the second frame 35 is connected to the end of the third frame 36. The first frame 34, the second frame 35, and the third frame 36 are connected to form an "n" shape, and the end corresponding to the second frame 35 is open, so that the frame structure 30 is a semi-enclosed frame structure. The two ends of each transverse reinforcement 41 are fixedly connected to the frame structure 30, the transverse reinforcement 41 is parallel to the second frame 35, and the two ends of the transverse reinforcement 41 are respectively connected to the corresponding first frame 34 and the third frame 36.

[0050] A plurality of reinforcing grooves 331 are provided on the upper surface of the frame structure 30 adjacent to the reinforcing structure 40. The reinforcing grooves 331 are provided in a direction parallel to the extension direction of the frame structure 30. For example, the reinforcing grooves 331 are arranged along the x direction on the upper surfaces of the first frame 34 and the third frame 36, and along the y direction on the upper surface of the second frame 35. A supporting protrusion 332 is defined between two adjacent reinforcing grooves 331, and the supporting protrusion 332 is used to support the liquid cooling plate 10. By providing the reinforcing grooves 331 and the supporting protrusion 332 on the surface of the frame structure 30, the overall structural strength of the frame structure 30 is greatly increased, the weight of the frame structure 30 is reduced, the processing difficulty of the frame structure 30 is reduced, the cost is reduced, the supporting area of ​​the frame structure 30 for the liquid cooling plate 10 is increased, and at the same time, the supporting strength of the frame structure 30 is increased, and the carrying capacity of the liquid cooling plate 10 for the objects located above is further improved. The plurality of support protrusions 332 in the frame structure 30 abut against the liquid cooling plate 10 to support the liquid cooling plate 10 and items thereon. The reinforcement grooves 331 can also dissipate the heat absorbed by the liquid cooling plate 10 .

[0051] According to some optional embodiments, the reinforcement groove 331 extends continuously along the upper surface of the frame structure 30. Exemplarily, after the first frame 34, the second frame 35, and the third frame 36 are spliced ​​together, the reinforcement grooves 331 on different frames are connected.

[0052] In the above scheme, a reinforcement groove 331 is opened on the upper surface of the frame structure 30 close to the reinforcement structure 40, and the reinforcement groove 331 extends continuously along the upper surface of the frame structure 30 without interruption in the middle, forming the same shape as the frame structure 30, so that the overall support strength of the frame structure 30 can be further increased, while increasing the heat dissipation of the liquid cooling plate 10, and the heat absorbed by the coolant in the liquid cooling plate 10 can be dissipated in time, thereby reducing the temperature deviation of different areas of the liquid cooling plate 10 and improving the cooling effect of the liquid cooling plate 10 on the product.

[0053] According to some optional embodiments, the frame structure 30 includes a connecting portion 32 and a supporting portion 33, and the connecting portion 32 and the supporting portion 33 are integrally formed. The connecting portion 32 is located on a side away from the reinforcing structure 40, and the supporting portion 33 is adjacent to a side of the reinforcing structure 40. The reinforcing groove 331 is provided on the surface of the supporting portion 33, and the cross section of the supporting portion 33 is comb-shaped.

[0054] In the above solution, the connecting portion 32 is rod-shaped and hollow, and the supporting portion 33 is located inside the connecting portion 32. The two are integrally formed, or the connecting portion 32 and the supporting portion 33 are welded to increase the supporting strength of the frame structure 30. The connecting portion 32 is usually connected to the liquid cooling plate 10 by screws, and the supporting portion 33 is attached to the liquid cooling plate 10 to assist the liquid cooling plate 10 in supporting the object and dissipating the heat of the liquid cooling plate 10.

The lower surface of the support portion 33 is located above the lower surface of the connection portion 32, and the lower surface of the support portion 33 and the side wall of the support portion 33 form a mounting groove 333. The two ends of the transverse reinforcement member 41 can be fixed in the mounting groove 333 and can be installed in the mounting groove 333 by welding or screws. The mounting groove 333 is set on the lower surface of the support portion 33, which reduces the impact on the strength of the reinforcement groove 331.

[0056] According to some optional embodiments, a receiving groove 411 is provided on the lower surface of the transverse reinforcement 41 , and both ends of the longitudinal reinforcement 42 are fixedly connected to the adjacent transverse reinforcement 41 through the receiving groove 411 .

[0057] In the above solution, both ends of the longitudinal reinforcement 42 can be fixed in the receiving groove 411 by welding, and the receiving groove 411 is arranged on the lower surface of the transverse reinforcement 41, and a protrusion is formed on the upper surface of the transverse reinforcement 41 corresponding to the position of the receiving groove 411, thereby increasing the supporting strength of the transverse reinforcement 41 to the liquid cooling plate 10. Preferably, the receiving groove 411 is arranged on the side of the transverse reinforcement 41 close to the longitudinal reinforcement 42, so that the longitudinal reinforcement 42 will not penetrate the transverse reinforcement 41, and will not affect the supporting strength of the transverse reinforcement 41.

[0058] According to some optional embodiments, the cross-section of the reinforcement groove 331 is U-shaped, so as to dissipate the heat of the liquid cooling plate 10 in a timely manner, and if the liquid cooling plate 10 leaks, the reinforcement groove 331 can collect the leaked liquid.

[0059] According to some optional embodiments, the outer wall of the connection part 32 is provided with a hanging block 50, and the hanging block 50 can be fixed on the connection part 32 by welding. The hanging block 50 is provided with an insertion hole 51 along the insertion direction, and the insertion direction is the direction in which the hanging block 50 is inserted along the side wall of the connection part 32. One end of the hanging block 50 is located in the connection part 32 and is connected to the connection part 32, so a reserved groove 52 is provided on one side of the hanging block 50 adjacent to the support part 33, and the reserved groove 52 is connected to the insertion hole 51. Usually, after the hanging pin is inserted into the insertion hole 51, it needs to be rotated to lock it. Therefore, the hanging block 50 is provided with a reserved groove 52 at the end of the connection part 32, and the hanging pin can complete the rotation operation in the reserved groove 52 without interfering with the connection part 32.

[0060] According to some optional embodiments, the upper surface of the liquid cooling plate 10 is provided with a second support member 60, which can be welded on the surface of the liquid cooling plate 10, and the second support member 60 is arranged at intervals along the width direction parallel to the liquid cooling plate 10, and the second support member 60 is used to support the cooling object, so that a gap is formed between the cooling object and the liquid cooling plate 10, so as to avoid the problems of bending, breaking, low heat dissipation efficiency, etc. of the liquid cooling plate 10.
