[0022] See Figure 1 The embodiment of the application is a brazing integrated liquid cooling copper bar, which comprises a copper bar 1; the copper bar 1 has two waist-shaped holes 2 passing through both ends of the copper bar 1; the copper bar 1 and the waist-shaped holes 2 on the copper bar 1 are an integrated structure produced by the up-drawing continuous casting and continuous extrusion process. After the copper bar 1 plate is heated and melted to form copper liquid in the up-drawing continuous casting furnace crucible, the copper liquid flows into the holding furnace from the smelting furnace, and the copper liquid in the holding furnace is pressed into the crystallizer under the action of atmospheric pressure, and is cooled and solidified into a shape under the action of the cooling water in the crystallizer, and then is drawn out by the traction device and enters the take-up device to form an oxygen-free copper casting rod. As a preferred embodiment, the up-drawing continuous casting furnace crucible is a graphite crucible. Further, the oxygen-free copper casting rod is sent into the extruder for extrusion, and the oxygen-free copper casting rod is sent into the extruder after being preheated in the high-temperature copper rod after being heated, and the oxygen-free copper casting rod is sent into the extruder after being brushed on the surface. Through the joint action of the extrusion wheel and the compaction wheel, the oxygen-free copper casting rod is formed after extrusion, and the core rod is inserted into the core rod hole position in the extrusion die to fix the copper in the die and prevent the copper from flowing in the die to ensure the formation of a through hole during extrusion. As a preferred embodiment, the extruder should use a continuous extruder.

[0023] Further, the two sides of the copper bar 1 are designed in a semicircular arc shape, which not only facilitates close fitting with other components, but also increases the heat dissipation area and improves the heat conduction efficiency. In the liquid cooling system, the heat transfer and dissipation can be effectively accelerated to ensure that the equipment still maintains stable temperature during high-load operation and improves the overall heat dissipation performance of the system.

[0024] Further, the width of the copper bar 1 is 50 mm, the thickness is 4 mm, and the length is 150 mm. This size design not only meets the needs of various application scenarios, but also ensures the accuracy and adaptability of the copper bar during brazing. At the same time, this standardized size also facilitates quality control and inventory management during production.

[0025] Further, the copper rod for producing the copper bar 1 is melted and cast with A-grade copper, and the copper rod meets the standard of high-purity oxygen-free copper. The purity of A-grade copper is high, and the casting rod produced in cooperation with the graphite crucible meets the standard of high-purity oxygen-free copper, reducing the influence of impurities and oxygen content on performance.

[0026] Further, the width of the waist-shaped hole 2 is 22mm, the thickness is 2mm, and the two sides of the waist-shaped hole 2 are designed in a semicircular arc shape. The distance between the upper and lower inner walls of the waist-shaped hole 2 and the upper and lower end faces of the copper bar 1 is 1mm. The width, thickness, and semicircular arc shape of the two sides of the waist-shaped hole 2 of the embodiment not only optimize the flow path of the cooling liquid in the copper bar, reduce fluid resistance, but also improve cooling efficiency; at the same time, the distance between the upper and lower inner walls of the waist-shaped hole 2 and the upper and lower end faces of the copper bar 1 is 1mm, which ensures the uniform distribution of the cooling liquid in the copper bar, further improving the heat dissipation effect.
