Description
The utility model relates to a kind of cpu heat fixed sturcture, is applied in the computer system, and a kind of fixed sturcture that supports heatsink weight by computer chassis is provided.
In computer system, have a central processing unit (CPU) on the motherboard, be responsible for the work of the computing of data.Circuit chip in the CPU can produce heat energy when carrying out computing work rise cpu temperature, if the temperature of CPU rises to a too high temperature, will make the work of CPU become unstable and even cause the phenomenon of computer crash.Therefore above the CPU of motherboard, can install a metal heat sink usually additional, the aluminium matter that described heating radiator is generally high-termal conductivity and is easy to shape.As a kind of traditional fixing structure of radiator that Figure 1A painted.On a CPU socket (socket) 1, be fixed with a CPU2, on described CPU2, then be fixed with a heating radiator 3, described heating radiator 3 is to be interlocked with described socket 1 by a cramp 4, make described heating radiator 3 be fixed in described CPU2 top, and the bottom contacts with described CPU2 upper end, outwards propagates by described heating radiator 3 in order to heat energy.
Because to the demand of high-speed Data Processing, impel CPU constantly progressive on making and designing, function and speed are become stronger day by day, meanwhile, the also relative raising with frequency of operation of operating voltage significantly promotes the heating power of CPU.And, make the temperature of CPU unlikely too high in order to reach enough radiating effects, and heating radiator is healed in design and is become complicated, the size increasing that becomes of also healing, and material also adopts thermal conductivity better copper simultaneously.So, cause the weight of heating radiator more and more big; Shown in Figure 1B, traditional heating radiator 3 is to be set directly on the motherboard 20, that is all weight is to be supported by motherboard 20, and for strengthening radiating effect, usually on heating radiator 3, also can install a radiator fan again, motherboard will bear the weight of heating radiator 3 and radiator fan being provided with on the position of CPU thus; But many pins that are arranged on electronic package on the motherboard are arranged usually at the bottom of motherboard 20, therefore be provided with the projection of the high motherboard of frame in two sides of motherboard 20, and when suffering external impacts or vibrations when computer, the weight that heating radiator 3 adds radiator fan adds all positions in motherboard cpu fully, general CPU is arranged on motherboard 20 ectocentral positions, and being two sides, motherboard is supported on the computer chassis, motherboard central authorities certainly will form bending, seriously then make the fracture of motherboard and projection junction.Therefore from strength to strength, under the situation that heatsink weight more and more weighs, heating radiator is arranged on the motherboard, bears the non-suitable design of weight of heating radiator by motherboard at cpu function.
The purpose of this utility model is to provide a kind of cpu heat fixed sturcture, in order to heating radiator is directly fixed on the casing, when computer is impacted or shake, avoids heating radiator that motherboard is damaged.
The purpose of this utility model is to realize like this, a kind of cpu heat fixed sturcture promptly is provided, in order to heating radiator is arranged at the top of CPU, CPU wherein is arranged on the motherboard, and described motherboard is arranged on the casing, it is characterized in that: described fixed sturcture comprises several the support columns of being located at described casing corresponding to described CPU position, and described support column passed through described motherboard by described casing, in order in conjunction with described heating radiator and support described heating radiator and be positioned at CPU top.
According to the disclosed cpu heat fixed sturcture of the utility model, be that several (for example four) support columns are set on casing, heating radiator supported and be fixed in appropriate location on the motherboard, for example, passed through motherboard and above CPU and can with the contacted position of described CPU end face.Several support columns wherein, preferably be distributed in CPU on the motherboard around, on motherboard, be formed with several perforation, pass for described support column.The lower end and the casing of support column are fixed, and the upper end then is connected fixingly with heating radiator by rights, to support heating radiator, the weight of heating radiator is directly born by casing, gets rid of the stressed of motherboard.
The mode of connection of aforementioned heating radiator and aforementioned support column can be any suitable form, for example, and can be by several screws directly with described heating radiator and the mutual sealed binding in upper end of described support column.In addition, also can at least one supporting seat be set in the upper end of described support column, supporting seat can be in order to accept and fixing described heating radiator.And the binding fixed form of supporting seat and heating radiator for example, more can relend by at least one cramp, with the mutual clip of supporting seat, and described heating radiator clip is fixed on the described supporting seat.
Advantage of the present utility model is, heating radiator directly supported by the fixed sturcture of design on computer chassis, so as to getting rid of heating radiator stressed to motherboard.
For making the purpose of this utility model, structural attitude and function thereof there are further understanding,, describe embodiment of the present utility model below in conjunction with accompanying drawing, wherein:
