Good heat sink combination. [Previous Technology] As integrated circuits develop toward denser and more complex circuits, the heat generated by their electronic components also increases dramatically. For this reason, a heat sink is usually installed on the top surface of the electronic components to assist heat dissipation. The locking method of the radiator in the commonly used heat sink combination is shown in US Patent Nos. 6,538,889 and 6,374,906. These two types of radiators each have a mounting hole at each of the four corners of the radiator base, and the mounting hole A locking device is built in, and the locking device is used to lock the heat sink to a locking hole of a circuit board. However, if this method is used to provide a through hole in the base of the radiator, the heat dissipation fins around the through hole of the radiator need to be destroyed, and the flow of the heat dissipation airflow will be disturbed, resulting in a decrease in heat dissipation efficiency. On the other hand, when this kind of locking method is used, the heat sink fan installed above the base will interfere with the locking operation of the locking device and the shape of the base of the heat sink cannot be used to lock the circuit board. There are many problems such as opening assembly holes. It can be seen that the existing heat sink assembly still has defects in practical use, and needs to be improved. The reason is that the author feels that the above-mentioned shortcomings can be improved. He has devoted himself to research and cooperated with the application of theories to finally propose a rational design and effectively improve the above-mentioned original creations. M262970 [New content] Therefore, the main purpose of this book is to provide a combination of heat sinks. The heat sink is firmly mounted to the circuit board without destroying the heat sink's fins and has good versatility.

The bolt includes a screwing bolt on one side of the fixed base plate, and a groove and a locking portion on the other side of the fixed base plate. The elastic member is sleeved. On the bolt and limited to the screw The retaining ring is installed in the groove of the bolt to prevent the bolt from coming out of the mounting hole. The outer surface of the side locking portion is provided with an external thread. The screw holes on the circuit board cooperate to lock the heat sink to the circuit board, and the bottom surface of the base of the heat sink is elastically attached to the top surface of the electronic component. The advantage of this creation is that you only need to drill four screw holes on the bottom surface of the radiator base, and then fix the two fixing base plates and the locking device with screws to the screw holes on the bottom surface of the radiator base M262970. Then use the lock.

The elastic member 222 is a spiral elastic yellow, which can be threaded into the bolt 221 through the locking portion 2213 of the bolt 221. The stop ring 223 is a ring-shaped sheet with an outer diameter slightly larger than the inner diameter of the mounting hole 2121 of the fixed bottom plate 21. The stop ring 223 is provided with a receiving hole 2231 at the center and a notch 2232 at the periphery. . The elastic member 222 is sleeved on the bolt 221 and is limited between the screwing portion 22Π and the fixed base plate 21, so that the fixed base plate 21 and the radiator 丨 form an elastic connection relationship with the bolt 221; the stop ring 223 is It is snapped into the groove 2212 of the bolt 221 to prevent the bolt 221 from coming out of the mounting hole 2121 of the fixing base plate 21.
