Embodiment 1
[0035]The invention provides a technical solution: a coated copper-aluminum composite sheet, including an aluminum foil base layer 1, a hemispherical groove 5 is evenly opened on one side of the aluminum foil base layer 1, and a hemispherical groove is evenly arranged on the side of the aluminum foil base layer 1 away from the hemispherical groove 5 The protrusion 6 is provided with a card slot 7 on one side of the inner wall of the hemispherical groove 5, and a heat dissipation fin 8 is installed inside the hemispherical groove 5, and one end of the heat dissipation fin 8 extends to the inside of the card groove 7 and is engaged with the card groove 7, The outer side of the cooling fin 8 is uniformly provided with a cooling groove 9, the side of the aluminum foil base layer 1 close to the hemispherical groove 5 is provided with a protective layer 2, and one side of the protective layer 2 is provided with a cooling hole 10, and one side of the cooling fin 8 is fixedly connected ...
Embodiment 2
[0039] The invention provides a technical solution: a coating copper-aluminum sheet composite process, comprising the following steps:
[0040] Step 1, surface treatment, put the aluminum foil into the cleaning solution to soak and clean, and then use the marble launcher to eject small particles of marbles on the surface of the aluminum foil until the surface of the aluminum foil is hit by the high-speed ejected marbles out of the hemispherical groove, and the aluminum foil is ejected The other side of the bead hits to form a hemispherical protrusion, drill a card slot inside the hemispherical groove, use a cleaning brush to scrub the surface after taking it out, and then rinse it with clean water;
[0041] Step 2, dry, fix the cleaned aluminum foil, turn on the hot air blower on both sides, simultaneously dry the surface of the aluminum foil and preheat the aluminum foil, insert the heat dissipation fins into the hemispherical groove and snap into the card groove to fix;
