Abstract

The utility model relates to a radiator which is used to assist electronic elements to carry off heat, comprising a plurality of heat radiating fins, air flows, air intake vents and air outlets. Air flows are arranged among adjacent heat radiating fins. One end of the air flow is an air intake vent, and the other end of the air flow is an air outlet. The width of the air intake vent is larger than the air outlet, so the air intake vent is larger than the air outlet. The air flow which is formed by the adjacent heat radiating fins of the utility model can increase the disorder degree of the air flow between the heat radiating fins and the wind rate which flows through the heat radiating fins. The flow of the air flow in the air passage can be accelerated and the flow resistance at the air intake vent can be reduced. As a result, the effect of heat radiation can be improved.

Description

Radiator

[technical field]

The utility model is about a kind of radiator, particularly a kind of radiator that is used for the auxiliary electron element radiating.

[background technology]

Continuous progress along with integrated circuit technique, the speed of service of electronic component constantly promotes, the heat of its generation also increases thereupon, if untimely heat with its generation is discharged, to cause its temperature constantly to raise, and then have a strong impact on the performance of its operation, can normally move for guaranteeing electronic component, usually at its mounted on surface one radiator so that heat is distributed apace.

The normal radiator that adopts has a pedestal and the some radiating fins of being located on the pedestal with the increase area of dissipation, the radiating fin of traditional radiator is generally arranged with parallel mode on pedestal, as shown in Figure 1, this radiator comprises a pedestal 11 and some radiating fins 12, this radiating fin 12 is arranged on the pedestal 11 with the parallel arrangement of a determining deviation, the side of this radiator is provided with a fan (figure does not show) to increase the flow velocity of air-flow 12 of radiating fins, and reach the purpose that promotes radiating effect, wherein airflow direction is shown in arrow among the figure.Because radiating fin 12 is set in parallel on the

pedestal

11,12 formed airflow path of adjacent radiating fin parallel with the air-out direction of fan, the mobile comparison rule of air-flow in airflow path, be difficult for producing turbulent flow, air-flow can not fully contact and take away heat with radiating fin 12, heat exchanger effectiveness between the two is lower, in addition, be subjected to the influence of viscous force between air-flow and the radiating fin 12, air-flow is slowing down gradually away from the flow velocity between the radiating fin 12 of air outlet, so only the radiating fin 12 in nearly fan end just has better radiating effect, radiating effect away from the radiating fin 12 of fan end reduces gradually, thereby the radiating fin 12 and the rate of heat exchange in the external world are slowed down, influence the radiating effect of entire radiator.

[summary of the invention]

The purpose of this utility model be to provide a kind of increase intake, with the extraneous good radiator of radiating effect that bigger rate of heat exchange is arranged.

The purpose of this utility model is achieved through the following technical solutions: the utility model radiator, have some radiating fins, have air flow channel between adjacent radiating fin, an end of this air flow channel is an air intake vent, the other end is an air outlet, and the width of air intake vent is big than air outlet.

Compared with prior art, between the adjacent radiating fin of the utility model the air port that the is formed into air flow channel big than air outlet, can increase the disorderly degree of air-flow between radiating fin, and the air-flow that is entered by air intake vent had the guiding and the function of degree of adding, and reduce the flow resistance at air intake vent place, increase the air quantity that flows through between radiating fin, and make air-flow be unlikely deceleration at back segment, thereby accelerate and extraneous rate of heat exchange, avoid the situation of long-pending heat to take place, and promote radiating effect.

With reference to the accompanying drawings, the utility model will be further described in conjunction with the embodiments.

[description of drawings]

Fig. 1 is the stereogram of existing radiator.

Fig. 2 is the stereogram of the utility model radiator.

Fig. 3 is the vertical view of the utility model radiator.

[embodiment]

Please consult Fig. 2 and Fig. 3 simultaneously, the utility model radiator comprises a pedestal 10 and the some radiating fins 20 that stand on the pedestal 10, these pedestal 10 lower surfaces fit in electronic component (figure does not show) surface, absorb the heat of electronic component generation and conduct to above-mentioned radiating fin 20, and then heat is distributed.

The spacing of adjacent radiating fin 20 on pedestal 10 dwindled gradually from a side to its opposite side of radiating fin 20, the bigger end of the spacing of this radiating fin 20 forms the air-flow air intake vent, and spacing forms air-flow air outlet, the air flow channel that roughly is taper 30 that 20 formation of adjacent radiating fin are phased down to air outlet by air intake vent than small end.

During use, one fan (figure does not show) can be set in the bigger side of radiating fin 20 spacings of radiator, air-flow blows to narrow end from its thicker end in the taper air flow channel 30 of convergent, also can in air flow channel 30, suck the fan of air-flow in the less couple positioned opposite one of radiating fin 20 spacings, make air-flow flow to narrow end from thicker end equally, air flow direction is shown in arrow among Fig. 2 and Fig. 3.

More than be not difficult to find out, the spacing that the adjacent radiating fin of the utility model radiator is 20 is dwindled gradually from a side to its opposite side of radiating fin 20, make each air flow channel 30 roughly be the taper of convergent to air outlet by air intake vent, then when work, air-flow flows into from the thicker end of air flow channel 30, and flow out from narrow end, increase the disorderly degree of air-flow like this 20 of radiating fins, make air-flow fully contact heat radiation with radiating fin 20, and the taper air flow channel 30 of convergent has water conservancy diversion and acceleration, can reduce the flow resistance at air intake vent place, increase and flow through the air quantity of 20 of radiating fins, and make air-flow be unlikely deceleration, accelerate and extraneous rate of heat exchange at the back segment of radiating fin 20, avoid the situation of long-pending heat to take place, thereby promote radiating effect.
