Abstract
The utility model discloses a spiral radiator. The radiator comprises a radiator body, a PCB installed on one end of the radiator body and a cooling fan installed on the PCB. The radiator body is provided with a machine cover which wraps the PCB and the cooling fan. One end of the radiator body, which is connected with the PCB, is provided with arc radiating ribs which are distributed spirally. A spiral direction of the radiating ribs is consistent with a rotation direction of the cooling fan during working. A wind path is formed between cambered surfaces of the adjacent radiating ribs. By using the radiator of the utility model, through arranging the arc radiating ribs which are distributed spirally, a heat dissipation surface is increased; the arc radiating ribs make the wind path from a middle part to an edge be longer and lengthens contact time of an air flow and a radiator surface. When the cambered surfaces of the spiral radiating ribs lead out the air flow, friction between the cambered surfaces of the spiral radiating ribs and the air flow is full and contact heat transfer effect is good. The spiral direction of the radiating ribs is consistent with the rotation direction of the cooling fan so that a rebound effect of the ribs to the air flow is reduced.
Description
Technical field
The utility model relates to a kind of spiral radiator.
Background technology
Radiator is the general designation for a series of devices of conduction, release heat.And radiating mode refers to the major way of this heat sink radiates heat.In thermodynamics, heat radiation is exactly heat transmission, and the transfer mode of heat mainly contains three kinds: heat conduction, thermal convection and thermal radiation.Material itself or when material contacts with material, the transmission of energy is just called as heat conduction, and this is the most general a kind of thermaltransmission mode.Such as, the mode that the direct contact zones of LED cooling fin fin base and LED are walked heat just belongs to heat conduction.Thermal convection refers to the thermaltransmission mode that mobile fluid (gas or liquid) is walked the torrid zone, " pressure thermal convection " radiating mode of more commonly radiator fan drive gas flow in the cooling system of LED.Thermal radiation refers to and relies on x radiation x transferring heat, daily modal be exactly solar radiation.These three kinds of radiating modes do not isolate, and in daily heat transmits, these three kinds of radiating modes are all to occur simultaneously, concur.
The straight muscle of the general employing of radiating ribs in present radiator.Adopt straight muscle heat radiation to have following shortcoming: cooling surface area is little, wind path is short, air-flow is had to certain rebound effect, and then the effect of impact heat radiation.
Now need the radiator that a kind of cooling surface area is large, wind path is long.
Utility model content
The purpose of this utility model, is to provide a kind of spiral radiator.
The solution that the utility model solves its technical problem is: spiral radiator, it comprises radiator body, is arranged on the pcb board of radiator body one end and is arranged on the cooling fan on pcb board, on described radiator body, be also provided with the cover of pcb board and cooling fan parcel, one end that radiator body is connected with pcb board is provided with the arcuation radiating ribs of Spiral distribution, when the hand of spiral of described radiating ribs is worked with cooling fan, the direction of rotation is consistent, between the cambered surface of adjacent radiating ribs, forms wind path.
As the further improvement of technique scheme, the junction of described radiating ribs and radiator body is provided with a plurality of air outlets, and the middle position of described cover is provided with circular fresh air inlet.
As the further improvement of technique scheme, the axis of described fresh air inlet overlaps with the axis of cooling fan.
As the further improvement of technique scheme, described radiator body is cylindric, and the quantity of described air outlet is 2, and air outlet is symmetrically distributed on the outer round surface of radiator body.
The beneficial effects of the utility model are:
Compare with adopting the radiator of straight muscle heat radiation, have following advantage:
1, strengthened cooling surface area;
2, arcuation radiating ribs is longer to the wind path at edge in the middle of making, and has lengthened the time that air-flow contacts with spreader surface;
3, the cambered surface of spiral helicine radiating ribs is when deriving air-flow, more abundant with gas current friction, the better effects if of transmission of heat by contact;
4, the hand of spiral of radiating ribs and the direction of rotation of cooling fan are consistent, reduce the rebound effect of rib to air-flow.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is further described.
Fig. 1 is the structural representation of radiator body of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is explosive view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, describe application of the present utility model in detail.
With reference to Fig. 1～Fig. 3, spiral radiator, it comprises radiator body 1, is arranged on the pcb board 6 of radiator body 1 one end and is arranged on the cooling fan 7 on pcb board 6, on described radiator body 1, be also provided with the cover 3 of pcb board 6 and cooling fan 7 parcels, one end that radiator body 1 is connected with pcb board 6 is provided with the arcuation radiating ribs 2 of Spiral distribution, when the hand of spiral of described radiating ribs 2 is worked with cooling fan 7, the direction of rotation is consistent, between the cambered surface of adjacent radiating ribs 2, forms wind path.
By the arcuation radiating ribs 2 of Spiral distribution is set, strengthened cooling surface area; Longer to the wind path at edge in the middle of arcuation radiating ribs 2 makes, lengthened the time that air-flow contacts with spreader surface; The cambered surface of spiral helicine radiating ribs 2 is when deriving air-flow, more abundant with gas current friction, the better effects if of transmission of heat by contact; The hand of spiral of radiating ribs is consistent with the direction of rotation of cooling fan, reduces the rebound effect of rib to air-flow.
Be further used as preferred embodiment, the junction of described radiating ribs 2 and radiator body 1 is provided with a plurality of air outlets 5, the middle position of described cover is provided with circular fresh air inlet 4, cooling air enters from fresh air inlet 4, after radiator fan 7, pcb board 6 and radiator body 1, from air outlet 2, go out successively, the heat producing on pcb board 6 is taken away.
Be further used as preferred embodiment, the axis of described fresh air inlet 4 overlaps with the axis of cooling fan 7, and such layout makes heat radiation evenly.
Be further used as preferred embodiment, described radiator body 1 is cylindric, and the quantity of described air outlet 2 is 2, and air outlet 2 is symmetrically distributed on the outer round surface of radiator body 1, and such layout makes heat radiation evenly.
More than that preferred embodiments of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
