Spiral heat dissipation aluminum alloy profile

Abstract

The invention discloses a spiral heat dissipation aluminum alloy profile. The spiral heat dissipation aluminum alloy profile is characterized in that the spiral heat dissipation aluminum alloy profile comprises a main base plate, a left wing plate and a right wing plate which are all long strip-shaped plates; one face of the main base plate is a heat dissipation joint surface, and the left wing plate and the right wing plate are connected to the two sides of the other face, opposite to the heat dissipation joint surface, of the main base plate; the left wing plate and the right wing plate are perpendicular to the joint surface, and the longitudinal direction of the left wing plate and the longitudinal direction of the right wing plate are consistent with the longitudinal direction of the main base plate; the right wing plate is connected with a spiral wing, the outer end of the spiral wing is connected with the right wing plate, and the spiral wing is coiled between the left wing plate and the right wing plate; the end, far from the main base plate, of the left wing plate is provided with an inverted hook; a buckle is arranged on the outer surface of the spiral wing, and a gap is reserved between the buckle and the inverted hook; the spiral wing is coiled, and the buckle can be clamped onto the inverted hook. By adopting the spiral heat dissipation aluminum alloy profile, the required extrusion pressure is small; the main base plate, the left wing plate, the right wing plate and the spiral wing define a longitudinal air passage so that strong convection can be formed, and the heat dissipation efficiency can be improved.

Problems solved by technology

The existing aluminum profiles used as heat sinks are all composed of a base plate and a wing plate. When in use, the base plate is in contact with the heating component, and then the heat is dissipated by the wing plate. The existing wing plates are all open and arranged side by side. Direct contact dissipates heat into the air, so air fluidity is crucial to its dissipating efficiency. When there is no wind, this structure cannot form large convection, so the heat dissipation efficiency is low

This kind of aluminum alloy profile is mostly produced by extrusion process. When producing extrusion-molded hollow tubular products, the aluminum alloy billet must first enter multiple flow channels to reach the extrusion port, and then merge and merge into one and extrude from the extrusion port. The alloy billet is separated into multiple channels during the process of entering multiple flow channels, which invisibly increases the resistance and requires higher extrusion pressure to form. When the multi-channel aluminum alloy billet is merged, it is also prone to wrinkles or cracks due to the stability of the process conditions. These are still pending technical solution
