Abstract
The utility model discloses a radiating type printed circuit board which comprises a substrate and screw holes arranged on the substrate. Radiating holes are evenly arranged on the circumference of each screw hole. The radiating type printed circuit board enables heat accumulated on the peripheries of the screw holes when the substrate is powered on to run to be dissipated in the ambient environment rapidly through the radiating holes arranged on the circumferences of the screw holes, and working performance of the printed circuit board can be effectively guaranteed.
Description
Technical field
The utility model relates to the printed wiring board technical field, relates in particular to a kind of heat radiating type printed wiring board.
Background technology
Printed wiring board is a kind of element of electronic product, and along with the development of electronic product, people also more and more pay attention to the heat dispersion of printed wiring board.Traditional printed wiring board generally comprises substrate and is arranged on four angles of substrate and is used for printed wiring board is arranged on screw on electronic product.During substrate energising work, the circuit on substrate will generate heat and produce a large amount of heats, and these heats must in time be dispersed into the service behaviour that just can not affect printed wiring board in the surrounding environment.Screw on the substrate of existing printed wiring board is because the needs attachment screw just can be arranged on printed wiring board on electronic product, when substrate energising work, easily gather a large amount of heats near screw and can't in time distribute, finally greatly having affected the service behaviour of printed wiring board.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of heat radiating type printed wiring board, in the time of can rapidly substrate being switched on work at dissipation of heat that the screw surrounding is gathered in the surrounding environment, the service behaviour of printed wiring board is effectively ensured.
In order to solve the problems of the technologies described above, the technical scheme content that the utility model adopts is specific as follows:
A kind of heat radiating type printed wiring board comprises substrate and the screw that is arranged on described substrate; Be equipped with louvre on the circumference of each described screw.
The utility model is by arranging louvre on the circumference of screw, thus in the time of can rapidly substrate being switched on work at dissipation of heat that the screw surrounding is gathered in the surrounding environment, the service behaviour of printed wiring board is effectively ensured.
In order to guarantee good heat dispersion and not affect the installation capability of screw, preferably, be provided with equably eight louvres on the circumference of each screw.
For heat radiating type printed wiring board of the present utility model being fixedly mounted on electronic product, preferably, the quantity of described screw is four, and described four screw correspondences are distributed on four angles of described substrate.
Preferably, described louvre is the through hole of adhesion metal layer on inwall or any through hole with other radiator structures.
Preferably, described metal level is the copper layer.
Compared with prior art, the utility model has produced following beneficial effect:
Heat radiating type printed wiring board of the present utility model is by arranging louvre on the circumference of screw, thereby in the time of can rapidly substrate being switched on work at dissipation of heat that the screw surrounding is gathered in the surrounding environment, the service behaviour of printed wiring board is effectively ensured.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the more preferably structural representation of embodiment of heat radiating type printed wiring board of the present utility model.
Embodiment
As shown in Figure 1, heat radiating type printed wiring board of the present utility model comprises substrate 1 and the screw 2 that is arranged on described substrate 1; Be equipped with louvre 3 on the circumference of each described screw 2.
The utility model is by arranging louvre 3 on the circumference of screw 2, thereby the dissipation of heat that gathers in screw 2 surroundings can be rapidly with substrate 1 energising work the time is effectively ensured the service behaviour of printed wiring board in the surrounding environment.
In order to guarantee good heat dispersion and not affect the installation capability of screw 2, particularly, be provided with equably eight louvres 3 on the circumference of each screw 2.
For heat radiating type printed wiring board of the present utility model being fixedly mounted on electronic product, particularly, the quantity of described screw 2 is four, and described four screw 2 correspondences are distributed on four angles of described substrate 1.
Particularly, described louvre 3 is the through hole 32 of adhesion metal layer 31 on inwall or any through hole with other radiator structures.
Particularly, described metal level 31 is the copper layer.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection range of the utility model claim within.
