Snap-fit ​​diversion aluminum alloy cooling profile mold

Abstract

The invention discloses a buckle-fit flow guide type aluminum alloy heat dissipation profile mold, which is characterized in that it includes a main base plate flow channel and a wing plate flow channel, the wing plate flow channel is connected to the main base plate flow channel, and the cross section of the wing plate flow channel is the same as the The cross-section of the flow channel of the main base plate is vertical, and there are at least three or more odd-numbered flow channels of the wing plate. The middle part is connected to the flow channel of the wing plate, and the free end of the limit horizontal plate flow channel is close to the direction of the main base plate, and the odd-numbered flow channel of the wing plate from one side is connected to the side of the flow channel of the adjacent limit plate plate away from the flow channel of the main base plate The elastic plate flow channel extending in the direction, the free end of the elastic plate flow channel is gradually away from the main substrate flow channel; the extrusion pressure is required to be small, and the extruded product can form a strong convection to improve the heat dissipation efficiency.

AI Technical Summary

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
