Abstract

The utility model relates to a heat radiator, for radiating the heat of central processor, wherein two sides of the radiator are arranged with a plurality of radiating fins with preformed spaces between nearby radiating fins, the bottom of the radiator is mounted with a heat conductive block at the center while part of the heat-conductive block is protruded outside the bottom of the radiator, to contact the heat-conductive block on the central processor when mounts the radiator on a printed circuit board, and suspend two side radiating finds above the printed circuit board, therefore, a radiating fan on the radiator can use the spaces between nearby radiating fins to blow air downwards to radiate the heat of other electric elements on the printed circuit board.

Description

Radiator

Technical field

The utility model relates to a kind of radiator, particularly a kind ofly can not only can also provide radiating effect to other electronic component of the adjacent side of CPU at CPU (central processing unit), to promote the radiator of heat radiation function.

Background technology

Tradition is used the radiator 6 on CPU 71, and as shown in Figure 1, this radiator 6 is to be an aluminium extruded type, and radiator 6 aluminium extrudeds form a base 61, and then one-body molded on the base 61 have a multi-disc radiating fin 62, above these radiating fins 62 radiator fan 63 is installed; So, this radiator 6 can be installed in CPU 71 tops of printed circuit board (PCB) 7,, by radiator fan 63 heat energy be blown to the external world again, and reach radiating effect so that the heat energy that is produced during with CPU 71 runnings brings to radiator 6.

But, the area of traditional radiator 6 can be greater than CPU 71, so when radiator 6 is installed on the printed circuit board (PCB) 7, removing middle place can fit with CPU 71, also can cover other electronic component on the printed circuit board (PCB) 7 of CPU 71 adjacent sides, cause electronic component herein to dispel the heat, and those electronic components are damaged easily.

Summary of the invention

The purpose of this utility model is to provide a kind of radiator, and this radiator also can provide radiating effect at other electronic component of the adjacent side of CPU except that the CPU heat radiation is provided.

The utility model can be realized by following measure:

Principal character of the present utility model is that this radiator is to be aluminium extruded type, form the multi-disc radiating fin in the radiator body both sides, these radiating fins can take shape on the radiator body with modes such as planing or aluminium extruded or scolding tin, and between the adjacent radiating fin space that is reserved with perforation, make the space form the passage that supplies circulation of air, and, the place is equipped with heat-conducting block in the middle of the bottom of radiator body, this heat-conducting block some is to protrude from outside the radiator body bottom, when making radiator be installed on the printed circuit board (PCB), its heat-conducting block is to fit on the CPU, the radiating fin of both sides then is and is suspended on the printed circuit board (PCB), so, so that make the radiator fan that is installed on the radiator can utilize the space between each radiating fin and air is down blown, and brush to the printed circuit board (PCB) of the adjacent side of CPU other electronic component.

The place is provided with a containing groove that is used for ccontaining heat-conducting block in the middle of the bottom of described radiator.。

The some of described heat-conducting block is to protrude from outside the radiator bottom.

Described radiating fin can be used the moulding of planing mode.

Described radiating fin can be used the moulding of aluminium extruded mode.

Described radiating fin can be used the moulding of scolding tin mode.

Advantage of the present utility model is: the some of heat-conducting block of the present utility model is to protrude from outside the radiator body base plane, making the radiating fin of both sides be unsettled places on the printed circuit board (PCB), and be reserved with the space of perforation between the adjacent radiating fin, so, just formed a vent passages, just can make the radiator fan that is installed on the radiator can utilize the space between the radiating fin and air is down blown, and brush to the printed circuit board (PCB) of the adjacent side of CPU other electronic component.

The utility model also will be described in further detail embodiment in conjunction with the accompanying drawings.

Embodiment

The utility model provides a kind of " radiator ", please refer to shown in Fig. 2,4, radiator 1 of the present utility model is to be applied on the CPU 21 of printed circuit board (PCB) 2, be provided with integrated multi-disc radiating fin 11 in the both sides of radiator body, radiating fin in the present embodiment is to be the planing moulding, and be the space 12 that is reserved with perforation between the adjacent radiating fin 11, just each radiating fin 11 to locate up and down be to be connected, radiator fan 3 then is installed above these radiating fins 11.

In the utility model, the place is provided with a containing groove 13 in the middle of the bottom of radiator body, and a heat-conducting block 14 is installed in this containing groove 13, so that make the radiating efficiency of entire radiator 1 can be higher by this heat-conducting block 14, its heat-conducting block 14 is the splendid copper material of heat-conducting effect, and these heat-conducting block 14 somes are to protrude from outside the radiator body bottom.

Please refer to Fig. 2, shown in Figure 4, during the utility model assembling, even radiator body is installed on the printed circuit board (PCB) 2 together with heat-conducting block 14, at this moment, heat-conducting block 14 is to be fitted on the CPU 21, the radiating fin 11 of both sides then is the top that is suspended on printed circuit board (PCB) 2, then radiator fan 3 is installed on the radiating fin 11 again, can roughly finish this assembling of radiator 1 on printed circuit board (PCB) 2.

Please continue with reference to shown in Figure 4, when radiator of the present utility model 1 used, this heat-conducting block 14 was because be copper material, so the heat energy that is produced can very efficiently CPU 21 be turned round the time brings on the radiating fin 11 of radiator 1, by radiator fan 3 heat energy is blown to the external world again, and reach radiating effect; In addition, when radiator fan 3 brushes air downwards, because of being reserved with the space 12 of perforation between the adjacent radiating fin 11, so that can pass through these space 12 formed passages, 3 air that down brush of radiator fan (arrow as shown in Figure 4) 12 are down brushed along the space, and the electronic component place of brushing to the printed circuit board (PCB) 2 of CPU 21 adjacent sides other, make those electronic components also can reach radiating effect.

Please continue with reference to shown in Fig. 3,5, be another embodiment of the present utility model, wherein, also can be formed with the multi-disc radiating fin 11 of equidistant arrangement on this radiator body, and also be reserved with the space 12 of perforation between the adjacent radiating fin 11 with the mode of aluminium extruded moulding.
