The utility model is mainly formed by that two pin rods are extended on the back side of a heat radiating fin; a heat conducting plate is provided with a circular punch hole and a long punch hole; moreover, the two pin rods are respectively inserted into the circular punch hole and the long punch hole. Therefore, the stead heat radiating effect of the heat radiating fin is kept.

Description

Central processing unit heat radiator with anti-rotating torque

The utility model relates to a kind of central processing unit heat radiator.

At present, be installed in the central processing unit (CPU) of computer inside, on handling running except that consumed power, maximum shortcoming is to produce high temperature, and high temperature influences the stability of its work relatively, therefore, the dealer in the design of computer except that the thermal diffusivity of integral body, need look that CPU is dispelled the heat especially, and the heat radiation of CPU at present is to see through that heat radiator is set up on the surface and fan is reached; CPU develops so far again, and its arithmetic speed is more and more faster, and output power is also brought up to 40 watts at present, and working temperature improves much relatively, and its radiating requirements was also big, and the radiating mode that is adopted also has pattern different from the past.

At Ying Daier the new CPU that releases remove in the encapsulation of body, still include outside group and establish the casket shell, as Fig. 1, shown in 2, it mainly is central processing unit (CPU) 12 to be arranged on the outside have on the plugboard (PCB) 11 of inserted terminal, and integral body is arranged in the casket shell 1, and the upper side of this central processing unit 12 just and the heat-conducting plate 13 of casket shell 1 touch to, derive by means of heat-conducting plate 13 and with the work high temperature of CPU12, and these heat-conducting plate 13 surface systems are preset with identical most circular perforations 15 of diameter and long perforation 14, the radiating effect of this heat-conducting plate 13 is limited, still need and borrow heat radiation such as heat radiator 16 heat abstractors such as grade, make things convenient for central processing unit 12 work to have more stability; And this heat radiator 16 is to be sticked on the heat-conducting plate 13 of device central processing unit 12 casket shells 1, relend clamping element 17 and insert putting in the groove that heat radiator 16 offered, collude on heat-conducting plate 13 tops according to one button pin 18, another button pin 18 passes the relative perforation 14 of heat-conducting plate 13, and the bottom surface of catching on heat-conducting plate 13; So, still, still can there be following shortcoming in installing fan (not shown) on the heat radiator 16:

1) one of clamping element 17 button pin 18 is to collude on heat-conducting plate 13 tops, and another button pin 18 is to pass perforation 14 to catch on heat-conducting plate 13 bottom surfaces; Though only provide holding force according to button pin 18, can make that fixed effect is quite firm longitudinally, but the horizontal fixing then possibility of some microslip; When heat radiator 16 bears rotating torque, (can produce nondirectional moment of inertia to heat radiator during fan running), clamping element 17 collude the button pin 18 on heat-conducting plate 13 tops most probably thereby elasticity throw off, cause heat radiator 16 and heat-conducting plate 131 to break away from; Heat radiator 16 can't provide CPU suitable radiating effect in case break away from heat-conducting plate 13, due to produce the stability that high temperature influences work relatively.

2) at Ying Daier the new CPU that releases, its relative working temperature improves a lot, the heat radiator that is adopted is also big, relative weight is heavier, only probably has and can't support with clamping element 17 hooks.

In view of this, the purpose of this utility model provides a kind of central processing unit heat radiator with anti-rotating torque, inserts extremely in heat-conducting plate with heat radiator bottom pin rod, makes the upper and lower clamping that cooperates clamping element, keeps heat radiator not throw off heat-conducting plate.

The purpose of this utility model is achieved in that a kind of central processing unit heat radiator with anti-rotating torque comprises heat-conducting plate, the heat radiator of casket shell and fastens heat-conducting plate and the clamping element of heat radiator, it is characterized in that: the heat radiator back side is stretched and is established two pin rods, and offer circular perforations and microscler perforation on the heat-conducting plate, and two pin rods are plugged on respectively in circular perforations and the microscler perforation.

Described pin rod and heat radiator are one-body molded.

Owing to adopt such scheme: guarantee the stable radiating effect of heat radiator.

Below in conjunction with drawings and Examples the utility model is further specified.

The exploded view of Fig. 1 located by prior art;

The assembled sectional view of Fig. 2 located by prior art;

Fig. 3 is the exploded view of the utility model exemplary embodiments;

Fig. 4 is the assembled sectional view of the utility model exemplary embodiments;

Fig. 5 is the another kind of pin rod part sectioned view of the utility model exemplary embodiments;

Among the figure: 1. casket shell 11. plugboards (PCB) 12. central processing units (CPU) 13. heat conduction 14. perforation 15. perforation 16. heat radiator 17. clamping elements 18. are buckled pin 2. heat radiator 21. pin rods

Present embodiment, as shown in Figure 3, heat radiator 2 is for being sticked on a heat-conducting plate 13 that tightly has above the casket shell 1 of central processing unit 12, its back side system stretches and is provided with two circular pin rods 21, this pin rod 21 is fastened in the circular perforations 15 that is engaged in heat-conducting plate 13, and it protrudes out the thickness that length is equivalent to heat-conducting plate 13, and its relevant position system is separately positioned on the center of gravity both sides appropriate location of heat radiator 2, one pin rod 21 is aligned in the circular perforations 15 of heat-conducting plate 13, and another pin rod 21 is in alignment with the microscler perforation 14 of heat-conducting plate 13.

As shown in Figure 4, heat radiator 2 is sticked on the heat-conducting plate 13 on the casket shell 1 of central processing unit 12 is housed, be plugged on respectively in circular perforations 15 and the microscler perforation 14 according to its two pin rod 21, again clamping element 17 integral body are inserted putting in the groove that heat radiator 2 offered, and collude on heat-conducting plate 13 tops according to one button pin 13, another button pin 18 passes the relative perforation 14 of heat-conducting plate 13, and the bottom surface of catching on heat-conducting plate 13; So, heat radiator 16 can be fixed on the heat-conducting plate 13 of casket shell 1, install the fan (not shown) more in addition on heat radiator 16, the conclusion characteristics are as follows:

1) heat radiator 2 utilizes its two pin rod 21 to be plugged in the circular perforations 15 and a microscler perforation 14 of heat-conducting plate 13, any direction of limiting to heat radiator 2 and heat-conducting plate 13 fully moves the rotation with any direction, effectively resist rotating torque, form a kind of locating effect relatively, after cooperating clamping element 17 hooks to live, can make heat radiator 2 be fitted in heat-conducting plate 13 surfaces fully, no matter when heat radiator 2 bears the stressed or rotating torque of any direction, its clamping element 17 neither meetings thereby elasticity are thrown off.

2) heat radiator 2 utilizes two pin rods 21 to be plugged in the circular perforations 15 and a microscler perforation 14 of heat-conducting plate 13, major part is supported itself weight, 17 of clamping elements are responsible for the button voltage supply and are tightly reached the elastic force that hook is lived relatively, need not to carry the weight of heat radiator 2, can can't not support because of the heavier clamping element 17 that makes of heat radiator 2 weight.

In addition, heat radiator 2 can stretch out pin rod 21 at its back side, as shown in Figure 5, this pin rod 21 can be by the directly impact briquetting down of bottom surface of heat radiator 2, the any direction that can finish limitation heat radiator 2 and heat-conducting plate 13 equally moves or rotates, and forms a kind of locating effect, anti-effectively rotating torque.
