Embodiment 2
[0024] As shown in Figure 1B, it is a schematic structural diagram of a second embodiment of the heat dissipation device of the present invention. The heat dissipation device includes a heat dissipation body 1, and the material of the heat dissipation body 1 is other metal materials other than aluminum. A layer of aluminum film 3, on the surface of the aluminum film 3 of the heat dissipation body 1, silver micron clusters 2 are attached.
[0025] In this embodiment, the thickness of the aluminum film should be at least 1 micron (μm), preferably an aluminum film with a thickness of 50 μm. According to needs, the aluminum film can be plated only on the heat dissipation surface where silver micro clusters need to be formed.
[0026] In the technical solutions of embodiment one and embodiment two of the heat dissipation device of the present invention, silver micron clusters are further attached to the outer surface of the heat dissipation body, which is equivalent to increasing t...
Embodiment 3
[0043] As shown in Figure 5, it is the flow chart of the third embodiment of the surface treatment method of the heat dissipation device of the present invention. This embodiment carries out surface treatment for stainless steel heat sinks, which includes the following steps:
[0044] Step 200, plating an aluminum film with a thickness of 50 microns on the surface of the stainless steel heat sink by electroplating;
[0045] Step 201, immerse the stainless steel radiator plated with the aluminum film in a hydrochloric acid solution with a concentration of 1.0 mol / L for 1 minute for corrosion treatment, then take it out, and clean it with deionized water;
[0046]Step 202, drip ammonia water with a concentration of 1.1 mol / L into 20 mL of a silver nitrate solution with a concentration of 0.12 mol / L, and titrate until the silver hydroxide (AgOH) precipitate disappears, thereby preparing a silver ammonia solution;
[0047] Step 203, adding 30ml of glucose solution with a concentra...
