Split flow-guide type aluminum alloy heat dissipating profile

Abstract

The invention discloses a split flow-guide type aluminum alloy heat dissipating profile. The split flow-guide type aluminum alloy heat dissipating profile is characterized by comprising a main radiator and an auxiliary radiator; the main radiator is composed of a main base plate and wing plates, and the main base plate and the wing plates are all long-strip-shaped plates; one face of the main base plate is a heat dissipating connecting face, the wing plates are connected to the face, opposite to a heat dissipating face, of the main base plate, the wing plates are perpendicular to the connecting face, the longitudinal directions of the wing plates are coincident with the longitudinal direction of the main base plate, the number of the wing plates is at least two, barbs are arranged at the edges of the sides, far away from the main base plate, of the wing plates, and the phase positions of the barbs on the adjacent wing plates are opposite; and the auxiliary radiator is provided with a connecting plate and connecting wings, the connecting wings and the wing plates are the same in number and correspond in a one-to-one manner, and clamping grooves matched with the barbs are formed in the sides, far away from the connecting plate, of the connecting wings. The required extruding pressure is small, only buckling is needed in using, strong convection can be formed, and the heat dissipating 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
