[0032] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, the orientation words such as "upper" and "lower" are generally defined as the direction of the drawing surface, and "inner" and "outer" refer to the inner and outer parts of the relevant components. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0035] The liquid cooling plate is a structure commonly used in liquid cooling heat dissipation, and a heat exchange medium can flow in the liquid cooling plate. After the liquid cooling plate exchanges heat with the nearby heat dissipation component, the heat of the heat dissipation component can be taken away, and heat dissipation and cooling can be realized.

[0036] In the related art, the heat conduction performance of the liquid cooling plate is limited by the structural strength, which affects the heat exchange efficiency between the liquid cooling plate and the heat dissipation component, and further affects the heat dissipation effect. Especially for the liquid cooling plate in the battery pack, the liquid cooling plate is generally arranged below the battery monomer. The structural strength of the liquid cooling plate needs to be high to ensure the safety of the battery pack, and the liquid cooling plate needs to dissipate heat for the battery monomer. The liquid cooling plate needs to balance the relationship between heat conduction and structural strength. For example, the liquid cooling plate needs to be provided with a groove or a convex part to strengthen the structural strength. When the groove or the convex part is provided, the contact area with the battery monomer is reduced, which affects the heat transfer of heat exchange, and further affects the heat dissipation effect of the battery monomer.

[0037] Therefore, as shown in Figures 1-4 An aspect of the present disclosure provides a liquid cooling plate 102, which includes a plate body 1 and a filler 2.

[0038] The plate body 1 is provided with a flow channel 12 for the cooling medium to flow. The plate body 1 has a first face and a second face arranged opposite to each other. The first face is arranged as a heat conduction face, and the first face faces the heat dissipation component 100 and is used for heat exchange with the heat dissipation component 100. The first face is provided with a containing groove 11.

[0039] The flow channel 12 in the plate body 1 is used for the cooling medium to flow. The flow of the cooling medium can take away the heat exchanged heat, and realize cooling and heat dissipation.

[0040] The filler 2 is filled in the containing groove 11. The filler 2 has heat conduction property. The filler 2 can exchange heat with the cooling medium in the flow channel 12, and the filler 2 is used for heat exchange with the heat dissipation component 100.

[0041] In the technical solution, the filler 2 has thermal conductivity, can realize heat exchange between the cooling medium and the heat-dissipating component 100, realize heat dissipation and cooling, and the plate body 1 can also realize heat exchange between the cooling medium and the heat-dissipating component 100, thereby realizing heat exchange in two paths. The filler 2 can produce an auxiliary heat exchange effect and can supplement the heat exchange demand that the plate body 1 cannot meet due to structural strength, thereby greatly improving the heat exchange efficiency. The accommodating groove 11 can accommodate the filler 2, the filler 2 and the plate body 1 can both exchange heat with the heat-dissipating component 100, and the filler 2 can also strengthen the structural strength of the plate body 1, thereby improving the structural strength of the plate body 1 and improving the protection effect on the battery pack.

[0042] The first surface can have thermal conductivity, and the second surface can not need thermal conductivity, thereby reducing the cost. The accommodating groove 11 is on the first surface. It can be understood that the accommodating groove 11 is located on the outer wall of the plate body 1, and the filler 2 can be directly filled in the accommodating groove 11, thereby facilitating processing and manufacturing. In addition, the filler 2 is also on the first surface, so that the filler 2 faces the heat-dissipating component 100, and the first surface and the filler 2 can exchange heat with the heat-dissipating component 100 at the same time, thereby realizing cooling and heat dissipation. In some examples, the first surface and the filler 2 located in the accommodating groove 11 can directly contact the heat-dissipating component 100, thereby realizing heat exchange. Of course, in other examples, the first surface and the filler 2 located in the accommodating groove 11 can indirectly contact the heat-dissipating component 100, thereby realizing heat exchange.

[0043] Optionally, in an embodiment of the present disclosure, the groove wall or groove bottom of the accommodating groove is provided as a rough surface, and the filler is bonded to the rough surface. The rough surface can be provided as a frosted surface, thereby improving the bonding strength of the filler and improving the heat transfer path.

[0044] Optionally, in another embodiment of the present disclosure, the groove wall or groove bottom of the accommodating groove is provided with a reinforcing protrusion, and the filler is bonded to the groove wall of the accommodating groove, the groove bottom of the accommodating groove, and the reinforcing protrusion. Part of the groove wall or groove bottom of the accommodating groove can be provided with a reinforcing protrusion. The reinforcing protrusion can increase the bonding area of the filler, improve the heat transfer path, and increase the structural strength of the plate body.

[0045] Optionally, in an embodiment of the present disclosure, the filler 2 is provided to fill the accommodating groove 11 and is flush with the groove opening of the accommodating groove 11, and the groove opening of the accommodating groove 11 is flush with the first surface. In this way, the filler 2, the first surface, and the heat-dissipating component 100 can be connected, the contact area is ensured, and the heat exchange effect is improved.

[0046] It can be understood that the groove of the accommodation groove 11 is flush with the first surface, that is, the accommodation groove 11 is recessed from the first surface, so that the groove of the accommodation groove 11 is flush with the first surface, and after the filler 2 is filled in the accommodation groove 11, the filler 2 is filled to the groove of the accommodation groove 11, the accommodation groove 11 is completely filled, that is, the accommodation groove 11 is filled and is in the same plane as the groove of the accommodation groove 11, and does not protrude from the groove of the accommodation groove 11, so that the first surface is a whole flat surface and there is no unevenness.

[0047] Optionally, in an embodiment of the present disclosure, the filler 2 comprises a heat-conducting material and an adhesive, the heat-conducting material is connected to the accommodation groove 11 through the adhesive, and the heat-conducting material has a thermal conductivity greater than that of the plate body 1. The heat-conducting material can achieve heat conduction, and the heat-conducting material has a thermal conductivity greater than that of the plate body 1, which can further improve the heat exchange effect and the cooling effect.

[0048] The heat-conducting material is connected to the accommodation groove 11 through the adhesive, which is conducive to production and manufacturing. The heat-conducting material can be diamond, silver, copper, copper alloy, aluminum nitride or magnesium alloy. The diamond has a very high thermal conductivity, which can reach 2000 W / (m·K) to 2200 W / (m·K), which is much higher than that of aluminum, which is 200 W / (m·K)-230 W / (m·K). Silver has very good heat-conducting performance, about 429 W / (m·K), which is better than that of aluminum. The heat-conducting performance of copper is about 398 W / (m·K), which is better than that of aluminum. Some copper alloys can have better heat-conducting performance than pure copper, while also providing additional mechanical properties, such as enhanced wear resistance and corrosion resistance. Aluminum nitride has good electrical insulation and high thermal conductivity, about 310 W / (m·K). The heat-conducting performance of magnesium alloy can not be as good as that of aluminum, but the density of magnesium alloy is lower, which can meet the demand for lightness.

[0049] Optionally, in an embodiment of the present disclosure, the filler 2 further comprises a reinforcing material, the heat-conducting material and the reinforcing material are both in the form of powder, the heat-conducting material and the reinforcing material are mixed with each other and connected to each other through the adhesive, and the reinforcing material is connected to the accommodation groove 11 through the adhesive. The reinforcing material can further improve the structural strength of the liquid cooling plate 102 and better protect the battery.

[0050] The heat-conducting material and the reinforcing material are in the form of powder, which can facilitate the mixing of the heat-conducting material and the reinforcing material, and can ensure the balance of heat conduction and structural reinforcement. It can be understood that the heat-conducting material and the reinforcing material are connected to each other through the adhesive, and then connected to the accommodation groove 11 through the adhesive, so as not to fall off, and to facilitate complete filling of the accommodation groove 11. Of course, in other examples, the heat-conducting material and the reinforcing material can also have other shapes, which are not limited herein.

[0051] The adhesive can also have thermal conductivity, while being able to improve certain mechanical strength and stability, and can also have electrical insulation. In some examples, the adhesive can be a silicone-based adhesive, an epoxy-based adhesive, an acrylate-based adhesive, or a polyurethane-based adhesive. Among them, the silicone-based adhesive has a wide temperature resistance range and good anti-aging performance. The epoxy-based adhesive is known for its excellent adhesion and mechanical strength, and usually has high hardness and stability after curing. The acrylate-based adhesive has the advantage of fast curing, and its viscosity and curing speed can be adjusted as needed. The polyurethane-based adhesive has good flexibility and impact strength.

[0052] Optionally, in an embodiment of the present disclosure, the accommodation groove 11 is arranged in a strip structure, and the accommodation groove 11 extends along a first direction; wherein the first direction is arranged as the length direction or the width direction of the plate body 1. By such arrangement, the heat exchange area with the to-be-cooled part 100 can be improved, and the heat exchange effect can be improved, thereby improving the cooling effect. In some examples, the first direction is the length direction of the plate body 1. It should be noted that the width of the accommodation groove 11 can be set as needed.

[0053] Optionally, in an embodiment of the present disclosure, the number of accommodation grooves 11 is multiple, and the multiple accommodation grooves 11 are arranged in parallel along a second direction; wherein the second direction is arranged at an angle with the first direction. Each of the accommodation grooves 11 is filled with the filler 2. By such arrangement, the structural strength of the liquid cooling plate 102 can be improved, and the filling amount of the filler 2 can be improved, thereby improving the heat exchange efficiency and the cooling effect. In some examples, the second direction can be the width direction of the plate body 1, the first direction is perpendicular to the second direction, and the specific number of the accommodation grooves 11 can be set according to the specific size.

[0054] Optionally, in an embodiment of the present disclosure, the plate body 1 includes a first plate 13 and a second plate 14, and the first plate 13 and the second plate 14 are at least partially arranged in a spaced manner. The flow channel 12 is arranged between the first plate 13 and the second plate 14, the accommodation groove 11 is arranged on the first plate 13, and the first plate 13 faces the to-be-cooled part 100.

[0055] In this configuration, the first plate 13 and the second plate 14 face to face, with the circumferential edge of the first plate 13 connected to one side of the second plate 14. A flow channel 12 is located between the first plate 13 and the second plate 14, allowing the cooling medium to flow between them. The first plate 13 serves as a heat exchange plate, possessing thermal conductivity. The side of the first plate 13 facing away from the second plate 14 is designated as the first surface, and the receiving groove 11 is located on this side. The second plate 14 serves as a support plate, providing protection by being located away from the battery cells. During application, the first plate 13 is positioned above the second plate 14.

[0056] Optionally, in one embodiment of this disclosure, a portion of the first plate 13 protrudes towards the second plate 14, forming a plurality of protrusions 15 on the side of the first plate 13 facing the second plate 14, and a plurality of recesses on the side of the first plate 13 facing away from the second plate 14, the recesses being configured as receiving grooves 11. The protrusions on the first plate 13 increase the structural strength of the first plate 13, thereby enhancing the overall structural strength of the liquid cooling plate 102. During the protrusion process, a recess is formed on the side of the first plate 13 facing away from the second plate 14; this recess, which is the receiving groove 11, facilitates the filling of the filler 2. The protrusions can be elongated, thus both the protrusions 15 and the recesses are elongated.

[0057] Optionally, multiple protrusions 15 are connected to the side of the second plate 14 facing the first plate 13. The multiple protrusions 15 divide the space between the first plate 13 and the second plate 14 into at least one cavity, which is configured as a flow channel 12. The connection between the protrusions 15 and the second plate 14 creates a spacing effect, forming at least one cavity. This alters the flow direction of the cooling medium between the first plate 13 and the second plate 14, increasing the residence time and thus prolonging the heat exchange time. This allows for the removal of more heat and improves the heat dissipation and cooling effect. In some examples, the multiple protrusions 15 divide the space between the first plate 13 and the second plate 14 into multiple cavities. These cavities are interconnected and arranged side-by-side with intervals, allowing the cooling medium to flow through them sequentially.

[0058] Optionally, in another embodiment of this disclosure, a partition plate may be provided between the first plate 13 and the second plate 14. The two ends of the partition plate are connected to the first plate 13 and the second plate 14 respectively.

Alternatively, a pipe may be provided between the first plate 13 and the second plate 14, serving as the flow channel 12. A receiving groove 11 is formed by recessing the side of the first plate 13 facing away from the second plate 14.

The heat-conducting adhesive part 101 can be arranged to connect the liquid cooling plate 102 and the battery cell together, so as to ensure that the two are connected together to exchange heat, and the heat-conducting adhesive part 101 can conduct heat, without affecting the heat exchange between the liquid cooling plate 102 and the battery cell. It can be understood that one side of the heat-conducting adhesive part 101 is connected to the first side of the plate body 1 and the filler 2, and the other side of the heat-conducting adhesive part 101 is connected to the battery cell.

[0061] Optionally, in an embodiment of the present disclosure, the battery pack further comprises a frame 103, a bottom plate 104, a buffer 105, and a cover plate 106, the buffer 105 being connected to the bottom plate 104, the liquid cooling plate 102 being connected to the buffer 105, the frame 103 being connected to the liquid cooling plate 102, the battery cell being arranged above the liquid cooling plate 102 and located in the frame 103, and the cover plate 106 being connected to the frame 103 and arranged above the battery cell.
