Description

Improved heating radiator

The utility model relates to a kind of heating radiator, particularly a kind of heating radiator of improved computer cpu.

Central processing unit (CPU) is the computer core, because demand, development and the integrated circuit production technology of computer technology improve constantly, the speed and the efficient that make CPU carry out are more and more fast, the speed that CPU carries out is faster, it is also higher that it produces corresponding heat, and if fail the heat of CPU is spread rapidly, very huge for the stability influence of computation.Therefore, be to solve the CPU problems of excessive heat, the most direct and simple mode promptly is to install a heat abstractor on CPU additional, the high temperature that CPU is produced can be led thermal source shedding by heat abstractor, to keep the degree of stability of CPU execution.And at present general heat abstractor is combined by fan and heating radiator, wherein, fan is to be fixed on the heating radiator, the base plate of heating radiator is then closely pushed down CPU, the high temperature that is produced when making the CPU running, promptly because of fan imports gas, by the heat radiation section of heating radiator thermal source is led to shed, and reach the function of heat radiation.Yet known heat spreader structures (seeing also Fig. 1), how heat radiator 11 and heat radiator base plate 12 is one-body molded with aluminium extruded type processing, the heating radiator loam cake 10 of again end face being offered air inlet 101 covers and forms, owing to be subject to pressing mold and extrusion technique, the windage face 11 of its heat radiator 11 is comparatively generous, the air-flow face that not only intercepts fan is bigger, heat-transfer rate is slower, and radiating groove 12 spacings are big, so heat radiator quantity is few, and area of dissipation is also little, heating radiator loam cake 10 is sealed heat radiator 11 again, thermal source all distributes from the two ends, front and back, produces harmful effect for the radiating rate of heating radiator, makes the fan poor effect.

In addition, still there is a kind of finned radiator structure the market at present, and as shown in Figure 2, it is with the moulding of rolling mode, then with heat radiator 14 and base plate 15 riveted joints or gummed, again with 13 combinations of heating radiator loam cake with heat radiator 14.But when assembling, need spacer region 141 between heat radiator 14 and heat radiator, so will reduce area of dissipation, and its assembling is comparatively difficult, difficult quality control.And the air-flow of this kind heat radiator obstruct face is also thicker, and the distance of its surface level and fan is too approaching again, and anti-drag consumes fan power every fan airstream, and the shortcoming of improving the aluminium extruded type processing heat radiator is not arranged.

This creator is because the various shortcomings on the structural design of known heating radiator, and cause many bad on practicality and the stability, be manufacturing experience and the technology accumulation of being engaged in the electronics five metals according to it, method at the various solutions of the concentrated research of above-mentioned shortcoming, after through continuous research and improvement, finally create a kind of improved heat spreader structures, many shortcomings of the known technology of forgoing.

Fundamental purpose of the present utility model is to provide a kind of improved heating radiator, and structure to promote heat conduction, the radiating effect of thermal source that CPU is produced, improves the computer stability in use by this.

The purpose of this utility model is achieved in that a kind of improved heating radiator, mainly include ventilative cover, heat radiation net sheet and base plate, it is characterized in that: the end face of this ventilative cover is provided with the top through hole of a plurality of hollow outs, and its two sides are provided with the side through hole of symmetrical a plurality of hollow outs; This heat radiation net sheet is provided with the thin slice of a plurality of through holes for the sheet body, the side through hole of the arrangement of its through hole, structure and the cover that lets in air is identical, this heat radiation net sheet is formed groups of fins through the front and back buckle, and the netted open-end hole that this groups of fins forms forms honeycomb to discharge orifice with corresponding the communicating of side through hole of ventilative cover.

Particularly, the utility model is with the monolithic impact briquetting with heat radiation net sheet, produce more traditional aluminium extruded type, the combined type heat radiation net sheet that the rolling type is thinner, the obstruct face of heat radiation net sheet is thinner, make the air-flow of fan intercept less, can reduce the adverse current that windage produces, and when equal area, it is many that the quantity of heat radiator can be used always again, strengthen contact area significantly with thermal source, and be provided with the through hole of a plurality of hollow outs at the sheet body, can form honeycomb to discharge orifice with corresponding the communicating of through hole of ventilative cover both sides, make the air-flow that fan imports can rapid smooth and easy circulation, reduce choked flow, the thermal source that gives out from CPU also can make progress rapidly and lead diffusing from the four sides and go out simultaneously, preferable heat-conducting effect is not only arranged, can make heat radiator reach best thermolysis again, and can give full play to fan functionality, and solve the problems of excessive heat of more and more fast CPU execution speed.

The utility model utilization is provided with the heat radiation net sheet of through hole and forms groups of fins, the through hole of corresponding ventilative cover, form the flow-guiding radiation net of honeycomb by this to discharge orifice, when fan imports air-flow, air-flow freely, and with the thermal source circulation and be spread in the top rapidly and all around on four sides, distribute speed and can strengthen thermal source, accelerate radiating effect, CPU is remained under the best working temperature, and then improve the computer stability in use.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.
