The utility model relates to can be assembled rapidly and can flatly closely be covered on the end face of central processing unit (CPU) chip, can evenly absorb heat and the cpu chip radiator pedestal that dispels the heat.

Usually, needed member of computer such as interface card, motherboard, data card etc. need by cpu chip control running, so cpu chip very easily generates a large amount of heats than other elements in the computing machine in operating process, this heat must be through the process of suitably distributing outwardly, and the life-span of parts decreases on every side otherwise also can make except itself quite being easy to damage.

And existing radiating mode is assembled in the radiator fan of cpu chip seat end with draw heat and discharge outwardly through one usually, and this kind radiating mode is generally put the fixing seat of forming by air feed fan lock, and circlip type and gummed solidify formula, and this three has following many shortcomings when using operation:

1. gummed solidifies formula and pastes cpu chip with the heat radiation glue and be combined into one, though there is not assembling fittings, in case have only fan failure appears, the then difficult dismounting of heat radiator and cpu chip, very easily cause the destroyed problem that can't distinguish and exist the cooling fluid sclerosis in cpu chip surface, form thermal chocking on the contrary.

2. circlip type is to block cpu chip with both sides, because the insufficient pressure of clip, causes easily can't fitting tightly between heat radiator and cpu chip and causes heat absorption and heat loss through conduction effect bad.

3. the long slab that extends along the assembled base two edges lacks flexibility because of the hard plate, must after forming body, the horizontal holding of assembled base also return once more by first dismounting CPU chip during assembling together with cpu chip, not only take a lot of work, even laterally holding is combined in promotion or rotates the surface of fixing the seat end friction cpu chip that then very easily causes assembled base up and down and the surface of destroying cpu chip, when the runners of dismantling, very easily damage when assembling cpu chip.

Therefore, above-mentioned traditional structure truly has the necessity that is improved.

Therefore, fundamental purpose of the present utility model is: provide and can bring into play the good heat absorption and the cpu chip radiator pedestal of heat radiation function so that heat radiator fits tightly on the surface of CPU wafer.

Comprise according to cpu chip radiator pedestal of the present utility model: the mounting of a square box panel seat body, in mounting two opposite side one-body molded two independence and have the lug of backacter separately, mounting is axially towards dividing into a monolithic lug with backacter, by forming the taper slotted eye down up, mounting central authorities offer one can be in conjunction with the square dead slot of the square block dish of heat radiator below projection at four jiaos of mountings place.

The one plate-like heat radiator that is square can respectively have through hole from top to bottom for four jiaos in heat radiator for the locking of radiator fan seat, extends to form one down along these card lower edge central authorities and can pass square dead slot and abut against in the square block dish of CPU top;

The mat screw from the taper slotted eye of bearing by wearing the through hole of heat radiator up down and screwing togather with nut;

The combination of mat said structure makes to be matched with assembles radiator fan on the heat radiator, form a complete cpu chip radiator structure.

Aforesaid cpu chip radiator pedestal is characterized in that: make that protrude out lug with backacter and mounting down in mounting bottom one-body molded and have elasticity, the lug that side direction can be had backacter pushes away to imbed into the cpu chip root edge and forms one.

Aforesaid cpu chip radiator pedestal, its feature also are to be formed with cross rail on the surface of heat radiator.

Aforesaid cpu chip radiator pedestal, its feature be again four screw and nuts be locked on the mounting end be with screw block set backward hold in the taper slotted eye.

Therefore, the utlity model has following advantage:

The utility model be with four screws 30 cooperate bearings oppositely with heat radiator 20 relatively to lock, and collude the root edge that is hung on cpu chip 40 with five

lugs
