Further, the two first mounting notches 213 are provided to be offset in the width direction of the first base plate 211, and the two second mounting notches 223 are provided to be offset in the width direction of the second base plate 221.
Specifically, as shown in fig. 2, the width direction of the first base plate 211 and the width direction of the second base plate 221 are the front-rear direction in the drawing, the two first mounting notches 213 are arranged to be shifted in the front-rear direction of the first base plate 211, and the two second mounting notches 223 are arranged to be shifted in the front-rear direction of the second base plate 221, for example, the position of the first mounting notch 213 on the left side on the first base plate 211 is more forward than the position of the first mounting notch 213 on the right side on the first base plate 211, and the position of the second mounting notch 223 on the left side on the second base plate 221 is more backward than the position of the second mounting notch 223 on the right side on the second base plate 221.
As shown in fig. 3, the positions of the two first limit lugs 11 and the two second limit lugs 12 on the bracket 10 correspond to the positions of the two first mounting notches 213 and the two second mounting notches 223, respectively, for example, in the first limit lug 11 and the second limit lug 12 on the left side of the bracket 10, the first limit lug 11 is located above and forward of the second limit lug 12; it can be understood that, in the first and second limiting lugs 11 and 12 located on the right side of the bracket 10, the first limiting lug 11 is located above and behind the second limiting lug 12, so that the two first limiting lugs 11 and the two second limiting lugs 12 have a better fixing effect on the first base plate 211 and the second base plate 221, the first base plate 211 can be prevented from relatively deflecting with respect to the second base plate 221, and the first cold-forging heat sink 20 and the second cold-forging heat sink 20 can be further prevented from being loosened with respect to the black ball assembly 200.

Therefore, the contact area between the first bottom plate 211 and the second bottom plate 221 and the black ball assembly 200 is large, which is beneficial to the black ball assembly 200 to transfer heat to the upper cold forging heat sink 21 and the lower cold forging heat sink 22, thereby improving the heat dissipation efficiency of the cold forging heat sink 20; on the other hand, the black ball mounting cavity formed by the first and second mounting edges 2112 and 2212 can be wrapped around the outer sidewall of the black ball assembly 200, so as to further improve the fixing effect between the upper and lower cold-forged heat sinks 21 and 22 and the black ball assembly 200.
According to some embodiments of the present invention, as shown in fig. 3 and 4, the first and second position-limiting lugs 11 and 12 are respectively formed by blanking and bent by stamping from the side walls of the bracket 10. Specifically, a part of material is cut off on the side wall of the bracket 10 through a blanking process to define a first limit lug 11 and a second limit lug 12, the side wall of the bracket 10 cannot generate plastic deformation in the blanking process, and the first limit lug 11 and the second limit lug 12 are bent in a stamping mode to clamp an upper cold forging radiator 21 and a lower cold forging radiator 22, so that the first limit lug 11 and the second limit lug 12 are convenient to process and manufacture, and the processing cost can be further reduced.
Alternatively, with continued reference to the embodiment shown in fig. 3 and 4, the side wall of the bracket 10 is punched to form a first U-shaped hole 13 and a second U-shaped hole 14, the portion surrounded by the first U-shaped hole 13 is punched and bent to form a first limit lug 11, and the first limit lug 11 extends obliquely upward in the direction toward the cold-forged heat sink 20; the portion surrounded by the second U-shaped hole 14 is bent by punching to form the second stopper lug 12, and the second stopper lug 12 extends obliquely downward in a direction toward the cold-forged heat sink 20. It is worth to be noted that the opening direction of the first U-shaped hole 13 is downward so that the first limiting lug 11 defined by the first U-shaped hole can be bent downward through stamping, the opening direction of the second U-shaped hole 14 is upward so that the second limiting lug 12 defined by the second U-shaped hole can be bent upward through stamping, and the first limiting lug 11 defined by the first U-shaped hole 13 and the second limiting lug 12 defined by the second limiting hole have better structural strength and cannot be broken in the stamping process.
