Abstract
The utility model provides a heat emission device arranged on a PCB plate, which comprises a cover plate and two heat sinks connected with the cover plate; wherein the cover plate is integrally molded with one of the heat sinks. The heat emission device of the utility model makes the cover plate is integrally molded with one heat sink, the other heat sink keeps independently, the structure is simple, the operation is easy and the cost is saved.
Description
[technical field]
The utility model relates to a kind of heat abstractor, relates in particular to the heat abstractor on a kind of power panel.
[background technology]
The heat abstractor of existing power supply plate mostly be with two independently fin and cover plate form, described two fin are vertically mounted on earlier on the pcb board, cover plate are screwed on fin again.Each fin is fixed by two pins, because 2 determined straight lines can not play stable effect.During production, respectively two fin are inserted earlier earlier, played cover plate again behind the mistake tin stove.In the process of crossing the tin stove, be easy to because the rolling of red-hot scolding tin comes fin jack-up, perhaps owing to artificial touch or shake pin transposition with fin.All play not upper cover plate through the pcb board behind the tin stove is a lot of like this, have to do over again because of the transposition of fin.
The structure of independent separate separately of existing fin and cover plate not only increases the station of playing cover plate, cause the waste of material and human cost, simultaneously, dilapidated because cross vibrations when welding or touching in the process of producing, cause a lot of problems such as can't fix, the cover plate screw can not get through or pin can't get out.
[utility model content]
The technical problem of the required solution of the utility model is to provide a kind of heat abstractor, and it is easy to processing, saves cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of heat abstractor is provided, is installed on the pcb board, it comprises a cover plate and two fin that are connected with cover plate; Wherein, described cover plate is with wherein a fin is one-body molded.
One fin of described heat abstractor is extended downward vertically by the lateral margin one of cover plate and forms.
The cover plate of described heat abstractor reaches with it, and the fin of one is installed on the pcb board by two pins.
The cover plate of described heat abstractor is connected by screw with another fin.
Compared with prior art, the utility model heat abstractor is with cover plate and wherein a fin is one-body molded, and keeps independent with another fin, and described cover plate and integrated with it fin are inserted on the pcb board, just has two one lines to fix.22 pins that are described cover plate and fin insertion pcb board, a line promptly is the contact wire of described cover plate and another independent fin.Convenient for production, phenomenon such as cover plate can not occur can't beating because of the fin transposition or do over again is easy to processing, saves cost.
[description of drawings]
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic top plan view that is made up the radiator that forms in the utility model heat abstractor by cover plate and one of them fin.
Fig. 2 is the schematic side view of radiator among Fig. 1.
Fig. 3 is the schematic diagram of fin among Fig. 1.
Fig. 4 is the structural representation of the pin of the utility model heat abstractor.
[embodiment]
See also Fig. 1 to Fig. 4, the utility model heat abstractor comprises a cover plate 2 and two fin 3, wherein a fin 3 is extended downward vertically by a wherein lateral margin one of cover plate 2 and forms and in conjunction with being an angle of 90 degrees, and another lateral margin of cover plate 2 is connected with screw with another fin (not shown), and two fin are inserted on the pcb board (not shown) by pin 10.Because cover plate 2 of the present utility model is with wherein a fin 3 is one-body molded, therefore can solve the simple problem that fin can't be fixed of prior art, simultaneously, also can save production cost, only need a die sinking, (fin 3 and cover plate 2 will carry out die sinking separately in the past) reduced station, saved human cost.Described cover plate 2 is connected with screw with another fin (not shown).Described cover plate 2 is provided with some louvres 20, the function that it has heat radiation and makes airflow.
During installation, at first will be independently fin insert in the pcb board, more described cover plate 2 and integrated with it fin 3 are inserted on the pcb boards, and cover plate 2 and fin independently are fixed up with screw.
Said structure has utilized triangle to have the principle of stability, adopts fin 3 and cover plate 2 integrated structures, in actual production, will stablize the operation of becoming reconciled well than independent fin; Described heat abstractor is that the another one fin still keeps independent structures with cover plate 2 and one of them fin 3 be combined into.Described cover plate 2 and integrated with it fin 3 are inserted on the pcb board, just have two one lines to fix: 2 are described cover plate 2 promptly is the contact wire of described cover plate 2 and another independent fin with 2 pin 10, one lines that fin 3 inserts pcb board.Convenient for production, cover plate 2 can not appear can't beating because of the fin transposition or phenomenon such as do over again.
Claims (4)
1. a heat abstractor is installed on the pcb board, and it comprises a cover plate and two fin that are connected with cover plate; It is characterized in that: described cover plate is with wherein a fin is one-body molded.
