The invention discloses a bidirectional ladder-shaped heat radiation fin which consists of a fixing surface, extending surfaces and connection surfaces, wherein the fixing surface and the extending surfaces are connected through the connection surfaces and form a ladder shape, and the fixing surface is provided with a screw hole for fixing. The heat radiation fin is characterized in that the number of the extending surfaces is two; the number of the connection surfaces is two; a first extending surface is connected to one end of the fixing surface through the first connection surface; a second extending surface is connected to the other end of the fixing surface through a second connection surface; and the first extending surface and the second extending surface are both provided with screw holes for mounting electronic elements. The heat radiation fin provided by the invention is mainly used for assistant heat radiation for a circuit board, has a simple structure, and has high adaptability, good stability and a good heat radiation effect.
Description
Technical field
The invention belongs to circuit board heat radiation field, particularly a kind of two-way stairstepping fin.
Background technology
On the circuit board owing to integrated a large amount of electronic components; Can discharge a large amount of heats during work; Cause the circuit board temperature to raise; The too high job stability that can influence electronic component of temperatures at localized regions; Therefore need to improve the radiating effect of circuit board; Reduce working temperature, guarantee its stability, increase the service life.
Common radiating mode is a finned on circuit board, through the heat fast Absorption of fin with circuit board, and through its radiating surface heat transferred is gone out, thereby reaches cooling-down effect.In the practical set operation; Often run into a kind of situation; Be that required heat dissipation region has two; Lay respectively at edges adjacent and two circuit boards at interval; And two required heat dissipation region are two ends, the gap symmetrical distributions with respect to two circuit boards; To this situation; Traditional solution is with two fin to be dispelled the heat in the zone of these two needs heat radiations respectively; And traditional fin that is used for the heat radiation of board edge position is equipped with the auxiliary retention portion that reaches the circuit board outside usually; To help fixing cooling fins; Gap as if between two circuit boards is too little; The auxiliary retention portion that then can't hold two fin; If the cancellation auxiliary retention portion, the fin stability that then is installed in board edge can be affected again, and need spend more time and energy at fit on.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency that exists in the prior art, provides a kind of simple in structure, and adaptability is strong, the two-way stairstepping fin of good stability and good heat dissipation effect.
For solving the problems of the technologies described above; The present invention provides a kind of two-way stairstepping fin; Said two-way stairstepping fin is made up of stationary plane, extended surface and joint face; Said stationary plane links to each other by joint face with extended surface and forms stairstepping; Said stationary plane is provided with the screw that is used for fixing; It is characterized in that: said extended surface has two; Said joint face has two; Said first extended surface is connected an end of stationary plane by first joint face; Said second extended surface is connected the other end of stationary plane by second joint face, is equipped with the screw that is used to install electronic component on said first extended surface and second extended surface.Through stationary plane being installed in two interstitial sites between the circuit board; First extended surface of stationary plane one end links to each other with the circuit board of this side; Second extended surface of the stationary plane other end links to each other with the circuit board of opposite side; Simultaneously two circuit boards are dispelled the heat; The area of stationary plane can be set according to the gap between two circuit boards; Through this two-way step-like heat radiating fin structure; Do not advance and to dispel the heat to adjacent two circuit board opposed edges positions simultaneously; Good stable installation property can also be provided; Simple in structure; Adaptability is strong, good stability, and radiating effect might as well.
Aforesaid two-way stairstepping fin is characterized in that: said stationary plane, first extended surface, first joint face, second extended surface and second joint face structure that is formed in one.The one-body molded more secure of two-way stairstepping heat radiating fin structure that makes also makes things convenient for large-scale production.
Aforesaid two-way stairstepping fin is characterized in that: said stationary plane, first extended surface, first joint face, second extended surface and second joint face are aluminum.The stationary plane of aluminum, first extended surface, first joint face, second extended surface and second joint face be heat radiator fast, and better heat radiating effect is provided.
The beneficial effect that the present invention reached:
Utilize the two-way stairstepping characteristics of fin, dispelled the heat in opposed edges position on adjacent two circuit boards simultaneously, and good stable installation property is provided; The assembling area that takies is little; Have very strong adaptability in the practical set operation, it is simple in structure, and radiating effect might as well.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; Two-way stairstepping fin is one-body molded by stationary plane 1, first extended surface 2, first joint face 3, second extended surface 4 and second joint face 5; And material is aluminum; Said first extended surface 2 is stairstepping through the end that first joint face 3 is connected stationary plane 1; Said second extended surface 4 also is stairstepping through the other end that second joint face 5 is connected stationary plane 1; Said stationary plane 1 is provided with the screw 6 that is used for fixing, and is equipped with the screw 7 that is used to install electronic component on said first extended surface 2 and second extended surface 4.
As shown in Figure 3; In the practical set operation; Be provided with that two circuit boards are adjacent arranges and certain clearance is left in the centre; Need the zone of heat radiation to be positioned at the opposed edges position on two circuit boards; The stationary plane 1 of two-way stairstepping fin is assemblied in the gap of two circuit boards; Make first extended surface 2 and second extended surface 4 ride over two board edges respectively; Through screw 8 with electronic component 9; First extended surface 2 is connected with first circuit board 10; Also pass through screw 8 with electronic component 9; Second extended surface 4 is connected with second circuit board 11; Through screw stationary plane 1 is connected with fixing point position in two circuit board gaps; This moment, the fixing point position of two-way stairstepping fin had three; Simple in structure, the installing space that takies is few, good stability; Can accomplish heat radiation simultaneously, good heat dissipation effect to specific region on two circuit boards.
The present invention is mainly used in circuit board is carried out auxiliary heat dissipation; Utilize the two-way stairstepping characteristics of fin; Dispelled the heat in opposed edges position on adjacent two circuit boards simultaneously; And good stable installation property is provided; The assembling area that takies is little; Have very strong adaptability in the practical set operation, it is simple in structure, and radiating effect might as well.
Above embodiment limits the present invention never in any form, and every other improvement and application that above embodiment is made with the equivalent transformation mode all belongs to protection scope of the present invention.
