Abstract
The utility model relates to a CPU radiating sheet which comprises a radiating sheet body and radiating fins. The radiating fins are arranged on the radiating sheet body and are arrayed in a rib shape. Two vertical supporting feet are arranged on the two sides of the radiating body downwards. The supporting feet and the radiating sheet body are connected in an integrally-forming mode. The two supporting feet are both provided with back flow holes. According to the CPU radiating sheet, the supporting feet of the radiating sheet body are both provided with the back flow holes which penetrate through the radiating sheet body, the back flow holes can enhance conduction of hot flow between the radiating sheet body and the radiating fins, so that a convection effect is enhanced, and accordingly the radiating performance of the radiating sheet is effectively enhanced.
Description
Technical field
The utility model relates to heat abstractor, relates in particular to a kind of CPU radiating fin.
Background technology
Heat radiator is a kind of device to the easy heat-generating electronic elements heat radiation in electrical equipment, how by aluminium alloy, brass or bronze are made tabular, sheet, splintery etc., as the cpu central processing unit in computer will be used sizable heat radiator, the power tube in televisor in power supply pipe, line pipe, amplifirer all will be used heat radiator.General heat radiator in use will be coated with the last layer heat-conducting silicone grease at electronic component and radiating rib contact surface, and the heat that components and parts are sent is more effective to be transmitted on heat radiator, then is dispersed in surrounding air through heat radiator.
Heat radiator on market is different because of purposes now, so the shape of heat radiator and heat sinking function are different.For example CPU radiating fin has absorbed heat and by the form of convection current, heat has been dissipated, and in the process of heat loss through convection, radiating effect is mainly determined by the surface area size of radiating fin and the convection current between radiating fin.The radiating effect of heat radiator can't reach requirement now.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of CPU radiating fin of good heat dissipation effect is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of CPU radiating fin, it is characterized in that, it comprises heat sink body and is arranged on described heat sink body the radiating fin that is the arrangement of rib shape, described heat sink body both sides are to having two vertical legs, described leg is connected with described heat sink body is one-body molded, and described two legs are equipped with the refluence hole.
In preferred embodiment of the utility model, further comprise, described refluence hole and described heat sink body connect.
In preferred embodiment of the utility model, further comprise, described radiating fin equidistantly is evenly arranged on described heat sink body.
In preferred embodiment of the utility model, further comprise, described radiating fin both side surface is provided with symmetrical tooth.
In preferred embodiment of the utility model, further comprise, described tooth is isosceles triangle.
In preferred embodiment of the utility model, further comprise, described leg lower end is fixedly connected with the PIN pin, and the connected mode of described PIN pin and described leg is riveted joint.
In preferred embodiment of the utility model, further comprise, described heat sink body bottom is provided with heat-conducting silicone grease.
The utility model has solved the defect existed in the background technology, the utlity model has following beneficial effect:
1. the utility model is equipped with the refluence hole at the leg of heat sink body, and this refluence hole and heat sink body run through, the conduction of hot-fluid between heat sink body and radiating fin can be strengthened in the refluence hole, strengthens like this convection action, thereby effectively strengthens the heat dispersion of heat radiator.
2. radiating fin of the present utility model is the rib shape and equidistantly is arranged in above heat sink body, and the radiating fin both side surface is provided with symmetrical tooth, and this structure has increased the surface area of radiating fin greatly, and cooling surface area strengthens heat dispersion and also improves.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
