Abstract

The utility model discloses a radiating device for a CPU (Central Processing Unit). The radiating device is characterized in that a position used for installing a fan is arranged on a radiator, and ribs at the position are hollowed out; the rib hollowed-out position and the CPU are non-correspondingly arranged at a set distance, and radiator ribs above the CPU are kept; and the fan is arranged at the hollowed-out position of the radiator, and a heat conducting pad is stuck on the part, to be in contact with the CPU, of the bottom surface of the radiator. The radiating method of the radiating device provided by the utility model mainly comprises the following steps that heat generated by the CPU and other power consumption chips passes through the heat conducting pad through a heat conducting mode and then are conducted to a substrate of the radiator, and then the heat is further conducted to the radiator ribs, and finally the heat is taken away along gaps between the ribs by cold air blown by the fan, so that the temperature of the CPU can be greatly reduced to realize the radiating of the CPU.

Description

A kind of CPU heat abstractor
Technical field
The utility model relates to the electronic equipment dissipating heat technical field, particularly relates to a kind of CPU heat abstractor.
Background technology
Along with the function of electronic equipment is more and more, to CPU(Central Processing Unit, central processing unit) requirement of processor is more and more higher.Heat radiation to CPU in wide temperature range has proposed Secretary.The radiating mode of CPU mainly contains at present: 1, forced air cooling heat radiation; 2, conduction cooling heat radiation.The little flat-type electronic product of business level and thermal value adopts the radiating mode of conduction cooling heat radiation that CPU is dispelled the heat more, and the general using fans such as the desktop computer that thermal value is large, industrial control equipment add the mode forced air cooling heat radiation of heating radiator.Also do not have in a kind of ready-made particular space scope that can satisfy Flat electronic equipment at present, solve the heat abstractor of 45w power consumption CPU.
The utility model content
The technical problems to be solved in the utility model is a kind of CPU heat abstractor, the problems referred to above that exist in order to solve prior art.
For solving the problems of the technologies described above, the utility model provides a kind of CPU heat abstractor, comprising:
Be provided for the position of provided with fan on heating radiator, the fin of this position is emptied; Empty position and the CPU offset control distance of fin, with the heating radiator fin reservation of CPU top; Fan is installed on the position of emptying of heating radiator, sticks heat conductive pad in the heating radiator bottom surface with the place that CPU will contact.
Further, the aerofoil fan of frame around fan is selected and do not had.
Further, the fin of heating radiator is horizontal, bar shaped fin.
Further, be provided with several longitudinal ventilation grooves on heating radiator.
Further, the position of the corresponding internal memory of heating radiator is emptied, and the heating radiator substrate of the position of emptying exists.
Further, fixed leg and the heating radiator used of installation of heat radiator is structure as a whole.
The utility model beneficial effect is as follows:
To be mainly the heat that produces on CPU and other power consumption chips conduct to the heating radiator substrate by heat conducting mode after through heat conductive pad (or heat-conducting silicone grease) to the utility model radiating mode, then further conduct to heat radiator fin, the cold wind that is blown by fan is at last taken away along the fin gap, can greatly reduce the temperature of CPU, realize the heat radiation of CPU.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, does not limit the utility model.
As shown in Figure 1, 2, the utility model embodiment relates to a kind of CPU heat abstractor, comprising: fan 1, the position is emptied in the centre that is installed on heating radiator 2, sticks heat conductive pad 3 in heating radiator 2 bottom surfaces with the place that CPU will contact.Radiating mode be the heat of generation of CPU and other power consumption chips by heat conducting mode through after heat conductive pad 3, conduct to the substrate of heating radiator 2, then conduct to the fin of heating radiator 2, the cold wind of being blowed heating radiator 2 fins by fan 1 is at last taken away.The aerofoil fan 1 of frame around fan 1 is selected and do not had can guarantee that like this fan 1 can dry to surrounding, and fan 1 is towards heating radiator 2 blowings, and cold wind heating radiator 2 fins of flowing through are taken away heat.
As shown in Fig. 3 ~ 5, for the air channel layout of the whole product of correspondence, the fin of heating radiator 2 is horizontal, bar shaped fin.In order to save the space of thickness short transverse, be provided for the position 4 of installation shaft flow fan 1 on heating radiator 2, the fin at these 4 places, position is emptied.Empty fin position 4 can not with the CPU corresponding position, the certain distance of should setovering keeps the heating radiator fin of CPU top, with the heat-sinking capability of heat radiation device 2.Heating radiator one side shown in Fig. 2 has increased several longitudinal ventilation grooves 5, the cold wind that the guarantees aerofoil fan more heating radiator fin of flowing through, thereby heat can be taken away by cold wind, promoted the heat-sinking capability of heating radiator 2.Can the meeting spatial installation requirements for the ease of heating radiator 2,7 places, position of heating radiator 2 corresponding internal memories are emptied, must guarantee the existence of heating radiator substrate after emptying, the heat of heating radiator substrate storage could conduct to the fin above substrate faster.The effect of substrate is the heat of storage area CPU, and is passed to fin corresponding in substrate.If there is no substrate under fin, fin will lose the effect of heat radiation.Be deformed at last special-shaped radiator.Fixed leg 6 and the heating radiator 2 of installation of heat radiator 2 use are structure as a whole, and form by Milling Process, have improved the contact gap precision of the chips such as heating radiator and CPU.
As can be seen from the above-described embodiment, to be mainly the heat that produces on CPU and other power consumption chips conduct to the heating radiator substrate by heat conducting mode after through heat conductive pad or heat-conducting silicone grease to the utility model radiating mode, then further conduct to heat radiator fin, the cold wind that is blown by fan is at last taken away along the fin gap, can greatly reduce the temperature of CPU, realize the heat radiation of CPU.
Although be the example purpose, preferred embodiment of the present utility model is disclosed, it is also possible those skilled in the art will recognize various improvement, increase and replacement, therefore, scope of the present utility model should be not limited to above-described embodiment.
