Sectional material used for low voltage switch shell

Abstract

The invention provides a sectional material used for a low voltage switch shell, relates to a heat radiation structure which is suitable for the low voltage switch shell, and provides the sectional material which is great in heat radiation effect and used for the low voltage switch shell. A cross section of the sectional material presents to be a U-shape. Opening edges of U-shape openings are respectively provided with sides which orient outwardly. External surfaces of U-shape two sides are provided with axial heat radiation fins. Inclined angles between the heat radiation fins and the sides present to be from 0 to 15 degrees. A current state of a technology of bending a thin plate to process the shell in the prior art is changed, and the aluminum sectional material is adopted to mold. When the sectional material is used, the sectional material is cut segment by segment according to height of a switch so that the single shell is obtained. After the surface of the shell is provided with the heat radiation fins, heat of the internal part can be better transmitted outwardly so that working environment of the internal part is better and thus reliability of the switch is enhanced.

Description

technical field [0001] The invention relates to a profile, in particular to a heat dissipation structure suitable for a low-voltage switch housing. Background technique [0002] In the prior art low-voltage switches, such as reversing switches, air switches, vehicle power supplies, etc., the shells are generally made of metal sheets to be folded into a U shape, and the surface is flat. The existing problem is that the heat dissipation effect of the switch during operation is low, which increases the failure rate and reduces the reliability of the switch. Contents of the invention [0003] Aiming at the above problems, the present invention provides a low-voltage switch housing profile with good heat dissipation effect. [0004] The technical solution of the present invention is: the section of the profile is U-shaped, and the edges of the U-shaped opening are respectively provided with sides facing the outside, and the outer surfaces of both sides of the U-shaped are prov...
