Description

The heat abstractor of central processing unit

The utility model relates to a kind of thermal component, relates in particular to a kind of bridging and is buckled on the wafer socket of central processing unit, to improve the heat abstractor of this central processing unit radiating efficiency.

Be applied to the central processing unit (CPU) in the host computer at present, along with the increase of application, not only function is promoted thereupon, and processing speed also promotes relatively.Yet, after central processing unit is carried out a period of time fast, internal wafer just can produce heat, temperature is risen, if no suitable heat abstractor, to cause the central processing unit of high price to burn, or influence it and carry out efficient, so present general settling mode is to install a radiating component that is made of the multi-disc radiating fin on central processing unit additional, and install a radiator fan by this radiating component, to improve the radiating efficiency of central processing unit.The stationary installation of radiating component wherein normally slightly is the fastener of Jiong shape with a section, be cross-placed on this radiating component, and the both sides with this Jiong shape fastener are buckled on the wafer socket again.But the stationary installation of this form, be only applicable to the cuboid shape radiating component that constitutes side by side by the multi-disc radiating fin, and can't be applicable to the present better cylindrical radiating component of radiating efficiency of developing, make and use the central processing unit that is plugged in wafer socket (Socket) form, can't use cylindrical radiating component than high cooling efficiency.

In addition, as shown in figure 13, generally applying to the drum type brake radiating component on the computer cpu (CPU) at present, is to be processed into by a solid pole stock, and its manufacture method is as follows:

(a) get the solid pole stock of a suitable length;

(b) end of this pole stock turning one radiator fan seat (101) axially certainly;

(c) with milling cutter milling pole stock outer peripheral face radially one by one, to constitute multi-disc with this pole stock center of circle row

The radiating fin (102) of row is to finish the manufacturing of this radiating component.

There is following shortcoming in the above-mentioned manufacturing course of this radiating component:
