For reaching above-mentioned purpose, the utility model provides a kind of heat pipe-type radiating fin that produces eddy current, it is characterized in that, includes:
One lamellar body;
A plurality of heat pipes hole is run through to be formed on the lamellar body and is passed with heating tube; And
Many to vortex generator, vertical projection is on lamellar body and corresponding each heat pipe hole, each vortex generator is a triangle, and with one jiao direction towards corresponding heat pipe hole, in addition, the rear that each is the left-right symmetry shape and is positioned at corresponding heat pipe hole for corresponding heat pipe hole vortex generator is so that during the airflow passes lamellar body, earlier by the heat pipe hole vortex generator of flowing through again.
The aforementioned hot pore is distributed as a plurality of files, and arrange along a longitudinal axis in each file heat pipe hole, and this longitudinal axis is parallel to the direction that air-flow is advanced, and each is left-right symmetry to vortex generator for the corresponding longitudinal axis and arranges.
Aforementioned each vortex generator is an acute angle with angle between the corresponding longitudinal axis.
Aforementioned each be that front and back dislocation is arranged to vortex generator.
There is a dividing plate aforementioned lamellar body both sides projection downwards respectively.
Aforementioned each dividing plate is parallel to the longitudinal axis.
The relative vertical projection of lamellar body has a flange around aforementioned each heat pipe hole.
Effect of the present utility model is, by above-mentioned technological means, the a plurality of of triangle and symmetric arrays can effectively make the air-flow that passes through become longitudinal turbulence to vortex generator, make air-flow can be fully and the heat pipe-type radiating fin carry out heat exchange, moreover, form an accelerating region between the vortex generator of each diabolo, order is quickened by the air-flow of this accelerating region, postpone the centrifugation in boundary layer, destroy the tail whirlpool behind the heat pipe hole simultaneously, the air-flow of rear end, heat pipe hole is and then accelerated according to this, and this further reaches the heat exchange effect at rear, heat pipe hole.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done concrete description:
Please refer to Fig. 1 to Fig. 4, the heat pipe-type radiating fin that the utility model can produce eddy current can be installed in the heat pipe 20 of a heat abstractor, and heat pipe also is connected to a radiator 30, by radiator 30 contact semiconductor chips, can dispel the heat to semiconductor chip.
The heat pipe-type radiating fin that the utility model can produce eddy current includes: a lamellar body 10, a plurality of heat pipes hole 11, many to vortex generator 12 and two dividing plates 15.
This lamellar body 10 has two smooth opposite faces for laminar.
Please with further reference to Fig. 5 to Fig. 7, this a plurality of heat pipes hole 11 is run through on the one side that is formed on lamellar body 10 and is passed with heating tube 20, around each heat pipe hole 11 relatively lamellar body 10 vertical projections one flange 111 is arranged so that be welded on the heat pipe 20.In addition, heat pipe hole 11 is distributed as a plurality of files, and arrange along a longitudinal axis X in each file heat pipe hole 11, and this longitudinal axis X is parallel to the direction that air-flow is advanced.
This many to vortex generator 12 vertical projections on lamellar body 10 and corresponding each heat pipe hole 11, each vortex generator 12 is a triangle, and with haply with one jiao direction towards corresponding heat pipe hole 11.In addition, each carefully says it to the rear that vortex generator 12 roughly is the left-right symmetry shape and is positioned at corresponding heat pipe hole 11 for corresponding heat pipe hole 11, is roughly to be left-right symmetry for corresponding longitudinal axis X to arrange.By above-mentioned vortex generator 12 external forms, arrangement mode and with respect to the priority position in heat pipe hole 11, in the time of can making the airflow passes heat pipe-type loose the lamellar body 10 of fin, earlier by heat pipe hole 11 vortex generator 12 of flowing through again.Behind airflow passes vortex generator 12, then be subjected to the guiding of vortex generator 12 and change, and then produce spiral helicine longitudinal turbulence, promote the exchange rate of air-flow and lamellar body 10.
In addition, among preferred embodiment, each vortex generator 12 is an acute angle with angle α between the corresponding longitudinal axis X, and the air-flow with the lamellar body 10 of flowing through has good eddy current to tell on for this reason.Again, dislocation was arranged before and after each can be vortex generator 12, increased the variability of the eddy current that produces so that can make air-flow and lamellar body 10 has better rate of heat exchange for this reason.
Each dividing plate 15 is from the projection downward vertically of lamellar body 10 both sides and be parallel to above-mentioned longitudinal axis X, and dividing plate 15 makes between the adjacent heat pipe-type radiating fin and to produce the space with as the air channel.
By above-mentioned technological means, the many of triangle and symmetric arrays can effectively make the air-flow that passes through become longitudinal turbulence to vortex generator 12, make air-flow can be fully and the heat pipe-type radiating fin carry out heat exchange, moreover, form an accelerating region between the vortex generator 12 of each diabolo, order is quickened by the air-flow of this accelerating region, postpone the centrifugation in boundary layer, destroy the tail whirlpool behind the heat pipe hole 11 simultaneously, the air-flow of 11 rear ends, heat pipe hole is and then accelerated according to this, further reaches the heat exchange effect at 11 rears, heat pipe hole for this reason.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
