',' In order to effectively reduce assembly costs and increase the cost [previous technology] Press, the current computer computing function% I α Μ is more oriented towards "light, thin, short, fast and fast execution, its shape constitutes the central processing unit ( The development of the "CPU" with "super-captured" architecture, especially the temperature generated when a new operation instruction is more different? Alas, it is also implemented in the implementation of a cooling system 'to enable the central processing unit to perform well ::::: Operation i has become an important subject of industry research. The main book is as shown in the first figure. It is a conventional fan and a fixed frame including a radiator 10a, a fixed frame 20a, and a fan 30a. The bottom surface of the radiator 10a is flat. On the surface of the central processing unit (CPU), and the "" part can be covered by a fixing frame 20a, and then fastened by screws and other components; the top surface of the fixing frame 20a is provided with a circular through hole. And a plurality of screw holes (not shown; shown) 'This through hole corresponds to the center of the fan 30a, and the wind load 30a and the fixing frame 20a are fixedly connected with screws to form a combined type of heat dissipation device = However' It is known that the structure of the fan and the fixed frame basically has the problem of ★: Since the fixed frame 2 a and the fan 3 0 a are separately installed, the fixed frame 20a and the radiator 10a screw must be used first when the assembly is down. The connection is set, and the fan 30a is locked on the upper part of the fixed frame 20a by screws, which increases the complexity of the assembly process, and the cost of these screws is not low, so the engine and the temple are scattered.
