Abstract

The utility model discloses radiating fins with a progressive expanding and radiating structure. The radiating fins comprise a radiating structure composed of a plurality of radiating fins, both ends of the plurality of radiating fins are respectively the designs of narrow edge and wide edge, to ensure all the radiating fins to be arranged in sequence and to integrally form a sector expanding structure, heat exchange flow channels with narrow front and wide rear are formed between all the radiating fins, to ensure the radiated airflow to quickly flow to the gaps between all the radiating fins along the flow channels and bring away the heat source, to achieve the efficacy and purpose of quickly and effectively reducing the heat source absorbed by the radiating fins.

Description

The fin that has gradual expansion radiator structure

Technical field

The utility model relates to a kind of fin, is specifically related to a kind of fin that has gradual expansion radiator structure.

Background technology

Along with the continuous progress and development of electronic technology, the multimedia computer that combines high image quality, high tone quality is subjected to general the liking and use of consumer, and has quickened the degree of computer universalness.And the consumption of computer Related product increases, and the development of also ordering about related industry is rapidly flourishing more.As well known, the performance of the usefulness of computer system depends primarily on employed motherboard, and installs on this motherboard such as central processing unit, memory body, wafer set etc.. the performance of various element.

Central processing unit and main wafer set with a new generation owing to possessed the more core texture of elaborate, therefore can provide quite high efficiency execution speed, and more powerful calculation function.Yet along with the significantly increase of operation usefulness, the temperature problem that central processing unit and wafer set are produced in the running more needs effective solution.In order effectively to reduce the operating temperature of each element on the motherboard, cause host board fault or damage to prevent that temperature is too high, how effectively to cool off the central processing unit element peripheral with it, become current motherboard design dealer urgently in an important topic of breakthrough.

The utility model content

The technical problems to be solved in the utility model provides a kind of fin that has gradual expansion radiator structure, it can change the design of the airflow direction of cooling fan on the motherboard, with the temperature of effective reduction central processing unit, and then the useful life and the usefulness of lifting motherboard.

For solving the problems of the technologies described above, the technical solution that the utility model has the fin of gradual expansion radiator structure is:

A plurality of fin radiator structure that is arranged in a combination, described each fin has leading backing, described leading backing two ends vertically extend a heat conduction fin respectively, heat conduction fin one end of described each fin is made as narrow limit, the other end is made as broadside, described each fin and with narrow limit to the combination of narrow limit, broadside to broadside, and at one end form the arc air guide hole.

The technique effect that the utility model can reach is:

Using beloid structural arrangement to form opening one end is arcuate structure, and the heat exchange runner form that is fan-shaped flaring, make the heat radiation cold airflow along heat exchange runner form, promptly flow to each fin gap and take away thermal source, reach the effect purpose of effective reduction thermal source that fin absorbs.

Among the figure, A radiator structure, B fan, B1 fit portion, 10 fin, 11 leading backings, 12 heat conduction fins, 120 narrow limits, 121 broadsides, 13 honeycomb ducts, 14 wind-guiding spaces, 15 collection air ports, 16 card divisions, 17 draw-in grooves.

Embodiment

As shown in Figure 1, the utility model has the fin of gradual expansion radiator structure, radiator structure A is arranged in a combination by a plurality of fin 10, a plurality of fin 10 are arranged back one end and are formed arc air guide hole 14, can make the gap of the cooling blast of cooperation fan B generation by above-mentioned arc air guide hole 14 along fin 10, rapidly with the cooling blast water conservancy diversion to each fin 10 gap, reach the effect purpose of the thermal source that effective reduction fin 10 absorbed.

Each fin 10 is a ㄈ font body, each fin 10 has the leading backing 11 of a rectangular sheet, leading backing 11 two ends vertically extend the heat conduction fin 12 of a short-movie shape respectively, heat conduction fin 12 1 ends of each fin 10 are narrow limit 120, loose with gradual expansion and extend to the design that the other end forms broadside 121 in this narrow limit 120, each fin 10 is arranged in order and with 120 pairs of narrow limits 120, narrow limit, the combination of 121 pairs of broadsides 121 of broadside, make between each fin 10 and form honeycomb duct 13 respectively, and at one end forming arcs of recesses air guide hole 14, arc air guide hole 14 blows the B1 of the fit portion fit setting that formula fan B has the circular arc end for putting down.

Fig. 2, Fig. 3, Fig. 4 are another embodiment of the utility model, each fin 10 is combined and forms the radiator structure A of fan shape, a plurality of fin 10 1 ends form the collection air port 15 of semicircular arc, concentrate by the cooling blast that collection air port 15 can produce fan B, and along the honeycomb duct 13 of 10 of each fin, rapidly the cooling blast water conservancy diversion is taken away the thermal source that fin 10 absorbs, reach the effect purpose of thermal source that effective reduction fin 10 absorbs.

Fig. 5 is another embodiment of the utility model, the two ends of each ㄈ font fin 10 opening port are respectively equipped with several L shaped

corresponding card divisions

16,16 nearly corners, parallel card division, each fin 10 both sides are respectively equipped with draw-in groove 17, each fin 11 is established by card division 16 and draw-in groove 17 mutual cards and is combined into radiator structure A, and reaching provides the user to assemble practicality purpose easily.
