[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, a fixing structure for a liquid cooling plate according to the present invention includes a base plate 1 and a protective plate 2 and a crossbeam 3 detachably connected to the base plate 1. The protective plate 2 and the crossbeam 3 are arranged perpendicularly. The protective plate 2 is provided with a receiving groove 21. Multiple receiving grooves 21 are provided and spaced apart along the length direction of the protective plate 2. Multiple crossbeams 3 are provided and spaced apart along the length direction of the base plate 1. The multiple crossbeams 3 are respectively inserted into and accommodated in the multiple receiving grooves 21.

[0026] The protective plate 2 and the crossbeam 3 are detachably connected to the bottom of the substrate 1. The protective plate 2 is longitudinally arranged on both sides of the substrate 1, and the crossbeam 3 is transversely arranged on the substrate 1. Multiple crossbeams 3 are spaced apart along the length of the substrate 1, and multiple receiving slots 21 are spaced apart along the length of the protective plate 2. When multiple crossbeams 3 are respectively inserted into the multiple receiving slots 21, it is ensured that the multiple crossbeams 3 and the protective plate 2 are perpendicularly arranged, increasing the contact area with the substrate 1, providing good support and load-bearing performance for the substrate 1, and further consolidating the structural strength of the substrate 1. The protective plate 2 and the crossbeam 3 adopt a detachable structure to select and adjust the number of installations, meeting diverse usage and maintenance needs. This utility model, through the detachable structure of the protective plate 2 and the crossbeam 3, allows for adjustment of the number of installations according to actual usage needs, making installation and disassembly convenient, maintenance and replacement efficient, and effectively reducing usage costs.

[0027] In this embodiment, the protective plate 2 is provided with a first connecting hole 22 and a first connecting screw 23 connected to the first connecting hole 22. The crossbeam 3 is provided with a second connecting hole 31 and a second connecting screw 32 connected to the second connecting hole 31. The base plate 1 is provided with a third connecting hole 11 and a fourth connecting hole 12. The first connecting screw 23 passes through the first connecting hole 22 and connects to the third connecting hole 11. The second connecting screw 32 passes through the second connecting hole 31 and connects to the fourth connecting hole 12. Specifically, the first connecting screw 23 passes through the first connecting hole 22 and connects to the third connecting hole 11, and the second connecting screw 32 passes through the second connecting hole 31 and connects to the fourth connecting hole 12, thereby realizing that the protective plate 2 is longitudinally installed on both sides of the base plate 1, and the crossbeam 3 is transversely installed on the base plate 1.

[0028] In this embodiment, multiple first connecting holes 22 and multiple first connecting screws 23 are provided, and the multiple first connecting holes 22 and multiple first connecting screws 23 are spaced apart along the length direction of the protective plate 2. Multiple second connecting holes 31 and multiple second connecting screws 32 are provided, and the multiple second connecting holes 31 and multiple second connecting screws 32 are spaced apart along the length direction of the crossbeam 3. Specifically, the multiple first connecting holes 22 and multiple first connecting screws 23 spaced apart along the length direction of the protective plate 2 effectively enhance the connection stability between the protective plate 2 and the substrate 1, and the multiple second connecting holes 31 and multiple second connecting screws 32 spaced apart along the length direction of the crossbeam 3 effectively enhance the connection stability between the crossbeam 3 and the substrate 1.

[0029] In this embodiment, the protective plate 2 is a hollow aluminum profile. A heat dissipation groove 24 is provided on the side of the protective plate 2 away from the crossbeam 3. The heat dissipation groove 24 is connected to the receiving groove 21. Multiple heat dissipation grooves 24 are provided, spaced apart along the length of the protective plate 2. Specifically, the protective plate 2 is a hollow aluminum profile, ensuring both good structural strength and air circulation. The heat dissipation grooves 24 are connected to the receiving groove 21, and multiple heat dissipation grooves 24 are spaced apart along the length of the protective plate 2, thereby reducing the temperature of the substrate 1 through the protective plate 2 and ensuring the operational stability of the substrate 1.

[0030] In this embodiment, the crossbeam 3 includes protrusions 33 and recesses 34 connected to the protrusions 33. Multiple protrusions 33 and recesses 34 are provided, and the multiple protrusions 33 and multiple recesses 34 are arranged alternately and integrally formed. Specifically, the alternating arrangement and integral forming of multiple protrusions 33 and multiple recesses 34 not only simplifies manufacturing and reduces manufacturing costs, but also provides good structural strength, improving the support and load-bearing stability of the crossbeam 3 on the substrate 1.

[0031] In this embodiment, the substrate 1 is provided with flow channels 4. The substrate 1 and the flow channels 4 are integrally formed and both are made of aluminum alloy. Multiple flow channels 4 are provided, and multiple flow channels 4 are arranged along the length direction of the substrate 1. Specifically, multiple flow channels 4 are arranged side-by-side on the substrate 1 and extend along the length of the substrate 1, which facilitates the flow of coolant and increases the flow path of the coolant. The coolant circulates in the multiple flow channels 4, absorbs heat through contact between the substrate 1 and the battery, and then dissipates the heat in a timely manner through external cooling devices (such as water pumps, radiators, etc.). This structural design can evenly distribute the coolant. The substrate 1 and the multiple flow channels 4 are both made of aluminum alloy. Preferably, AL6063-T6 aluminum rods are used. The AL6063-T6 aluminum rods are preheated to 500°C and then extruded through a die. The substrate 1 and the flow channels 4 are integrally extruded. The substrate 1 made of aluminum alloy has thin walls and high structural strength, and good heat dissipation. This allows the substrate 1 to be manufactured into a lightweight structure with a width of 395mm, a thickness of 10.0mm, and a wall thickness of 1.0mm, while also possessing high performance. With its high strength and low cost, this material is suitable for heat dissipation in large-size equipment. The flow channel 4 is manufactured to a length of 6.0 mm and a reinforcing rib thickness of 0.3 mm. After treatment at 530℃, water quenching, and artificial aging at 175℃ (T6), the tensile strength of the substrate 1 reaches 230 MPa. Through T6 heat treatment and the design of the reinforced structure, the compressive strength is increased by 30%. The extrusion molding process reduces production costs by more than 25%. The structural ratio of the substrate 1 and the flow channel 4 is optimized, taking into account both structural strength and heat dissipation performance. The weight is reduced by more than 40% compared to traditional liquid cooling plates. It is made of AL6063-T6 aluminum alloy in one piece through extrusion molding, which has high thermal conductivity (≥200W / m·K), medium strength (tensile strength ≥215MPa) and excellent extrusion molding properties. The substrate 1 and the flow channel 4 are integrally molded, which is simple and convenient to manufacture, reduces welding processes, and lowers production costs.
