Abstract

The utility model discloses a radiator which is arranged on the computer central processor or on a heating element, comprising a radiator and a heat pipe. Wherein, the radiator is formed by a plurality of heat radiating fins which are piled up and ranged slantwise. Flow passages are formed between each two adjacent heat radiating fins. The corresponding through holes are respectively arranged on the heat radiating fins. The through holes are used to be connected with the heat pipe which is provided with a heat absorption portion and a heat radiation portion. The heat absorption portion is used to contact with the heat source. The heat radiation portion is connected with the heat radiating fins. By using the sloped settings, the swirling air which blows downward can be introduced into the radiator to avoid the heat air current to be absorbed into the inlet area. So the effect of heat radiation of the radiator can be improved.

Description

Heating radiator

Technical field

The utility model relates to a kind of heating radiator, relate in particular to a kind of being installed on central processing unit (CPU) and the heater element, the eddy airstream that blows downwards can be introduced in the radiator, be inhaled into the air inlet zone to avoid thermal current, and then improve the heating radiator of radiating effect.

Technical background

Nowadays Computing is powerful and execution speed is very fast, its shape structure develops towards the direction of " light, thin, short, little " especially, especially central processing unit of new generation (CPU) is owing to the calculation function with hypervelocity, and the heat that is produced when carrying out operational order is more.Thereby how to utilize good heat conduction and cooling system, and this central processing unit can normally be moved under the working temperature of permission, become the important topic of those skilled in the art's research.

As shown in Figure 1, known radiator and fan component mainly comprise a radiator 10a, a fixed mount 20a and a fan 30a.Wherein the bottom surface of radiator 10a is flattened on the surface of central processing unit (CPU), and its outside can cover a fixed mount 20a, and is fixedly connected with assemblies such as screws again.End face at this fixed mount 20a is provided with circular port and a plurality of screw (not shown), and this circular port is corresponding with the center of fan 30a, with screw fan 30a is fixedlyed connected with fixed mount 20a, just forms heat sink assembly.

Yet, still there are following shortcoming in known radiator and fan component: because the bottom surface of the flabellum of this fan 30a and radiator 10a is apart from too far away, make the air-flow that fan 30a blows, be not easy to be blown into the bottom of radiator 10a, and, thereby these uncooled thermal currents are sucked once again by fan 30a because these thermal currents are away from the air intake zone of fan 30a.Therefore, the radiating efficiency of these heat abstractors is not high.Thereby, the circulation continuously that goes round and begins again, the gas flow temperature that is blown into radiator 10a is more and more high with making, and makes the radiating efficiency of heating radiator not good.In addition, the air-flow that this fan 30a is blown out is vortex shape, and radiator 10a is vertically set on the fan 30a, and this air-flow is directly impinged upon on the radiator 10a, thereby reduced the flowing velocity of air-flow significantly, further reduced the radiating efficiency of this heating radiator.

Therefore, at the variety of issue of above-mentioned known technology, designer of the present utility model concentrates on studies in conjunction with the experience of being engaged in the sector for many years, in line with excelsior spirit, has designed the utility model.
