Abstract
The utility model discloses a T-shaped radiating fin which comprises a radiating fin main body and is characterized in that the radiating fin main body comprises a transversely extending head structure and a longitudinally extending bottom structure, wherein the head structure and the bottom structure are connected to form a T shape; the joint of the head structure and the bottom structure is bent at an angle of 90 degrees; and the bottom structure is provided with a screw hole for fixing. The T-shaped radiating fin is mainly used for carrying out auxiliary heat dissipation on a circuit board, has a simple structure, saves space, is convenient to install and has good radiating effect.
Description
Technical field
The utility model belongs to circuit board heat radiation field, particularly a kind of T type 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, and heat transferred is gone out, thereby reach cooling-down effect through its radiating surface with circuit board; But traditional fin shape is merely the plane of a full wafer; The area of its radiating effect and radiating surface is directly proportional, and strengthens radiating effect if desired, and then radiating surface need be to expansion all around; Electronic component to the circuit board upper periphery has interference easily, and it is installed and also receives the restriction that electronic component is arranged on the circuit board.
The utility model content
The utility model technical problem to be solved is to overcome the deficiency that exists in the prior art, provides a kind of simple in structure, saves the space, the T type fin of easy for installation and good heat dissipation effect.
For solving the problems of the technologies described above; The utility model provides a kind of T type fin; Comprise heat sink body, it is characterized in that: said heat sink body comprises the head construction and the longitudinally extending polycrystalline substance of extending transversely, and said head construction and polycrystalline substance connect to form the T type; The junction of said head construction and polycrystalline substance is 90 degree bendings, and said polycrystalline substance is provided with the screw that is used for fixing.Link to each other successively with circuit board through the polycrystalline substance of screw with electronic component, heat sink body, easy for installation, the size of the polycrystalline substance of T type heat sink body and the size of electronic component adapt; Said head construction is 90 ° of bendings with polycrystalline substance and is connected, and perpendicular to circuit board surface, extends to both sides; Save the space; Simultaneously can guarantee enough big area of dissipation, simple in structure, good heat dissipation effect.
Aforesaid T type fin is characterized in that said head construction is provided with the screw that is used for fixing.Vertical fixing point position screw on the head construction and periphery is adjacent through screw links to each other, can auxiliary fixing T type heat sink body.
Aforesaid T type fin is characterized in that the head construction and the polycrystalline substance of said heat sink body are formed in one.The integrated formed structure good stability is fit to large-scale production.
The beneficial effect that the utility model reached:
Simple in structure, save the space, easy for installation and good heat dissipation effect.
Description of drawings
Fig. 1 is the structural representation behind the utility model fit on electronic component.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, T type heat sink body is made up of head construction 1 and polycrystalline substance 2, and head construction 1 is combined into the T type with polycrystalline substance 2; And the bending that formation 90 is spent in the connection, polycrystalline substance 2 is provided with screw 3, is used to install electronic component 4; And be connected to a fixed with circuit board, also being provided with screw 3 on the head construction 1, can be connected with the fixing point position of lateral vertical; Auxiliary fixing T type heat sink body, head construction 1 is formed in one with polycrystalline substance 2.
For traditional fin; T type fin shared area of plane on circuit board is littler, and the area of its polycrystalline substance 2 can correspond essentially to the floor space size of electronic component 4, guarantees and fully the contacting of electronic component 4; To absorb heat; And can extend to both sides under the situation of height-limited system perpendicular to the head construction 1 of circuit board, on the space flexibility bigger, can bring better heat radiating effect.
The utility model is mainly used in circuit board is carried out auxiliary heat dissipation, and it is simple in structure, saves the space, easy for installation and good heat dissipation effect.
Above embodiment limits the utility model never in any form, every above embodiment is made with the equivalent transformation mode other improve and use, all belong to the protection range of the utility model.
Claims (3)
1. T type fin; Comprise heat sink body; It is characterized in that: said heat sink body comprises the head construction and the longitudinally extending polycrystalline substance of extending transversely; Said head construction and polycrystalline substance connect to form the T type, and the junction of said head construction and polycrystalline substance is 90 degree bendings, and said polycrystalline substance is provided with the screw that is used for fixing.
