[0001] The utility model relates to the technical field of aluminum alloy radiator fin processing, in particular to a composite surface processing device for an aluminum alloy radiator fin. Background Art

[0002] In recent years, with the rapid development of the computer industry, the CPU runs at higher and higher speeds, and its heat generation is also getting higher and higher. If this type of heat dissipation problem is not handled properly, it will seriously affect the CPU performance and further affect the normal operation of the machine as a whole. Therefore, an aluminum alloy heat sink is needed to help dissipate heat.

[0003] As the integration of CPU becomes higher and higher, the chassis space is limited, and the surface area of ​​the heat sink is greatly restricted. In order to further improve the heat dissipation performance of the heat sink, it is necessary to use an aluminum alloy heat sink composite surface treatment device to increase the roughness of the heat sink, thereby increasing the actual surface area of ​​the heat sink. At the same time, radiation heat dissipation paint is sprayed on the surface of the radiator to increase the emissivity of the radiator surface and reduce the absorption rate of the heat sink surface, thereby reducing the surface temperature of the radiator and achieving the purpose of heat dissipation.

[0004] However, since the composite surface treatment device of aluminum alloy heat sink in the prior art has a relatively single function during treatment, some technologies only grind the surface of the heat sink, which is not convenient for processing products of different shapes, especially for further processing of complex parts that are not suitable for mechanical polishing, and is not convenient for improving the heat dissipation performance of the heat sink, affecting its later heat dissipation efficiency.

[0025] The adjusting and fixing mechanism 2 includes a limiting slide 201, a driving motor 202, a transmission shaft 203, an anti-collision baffle 204, a threaded rod 205, an installation connection block 206, a limiting nut 207, a reinforcement support rod 208, a placement plate 209, a fixing plate 210, a support plate 211, a hydraulic cylinder 212, a hydraulic push rod 213 and a clamping plate 214. The limiting slide 201 is fixedly arranged at the front end of the upper end of the device body 101, the driving motor 202 is fixedly installed at the right end of the inner end of the limiting slide 201, the transmission shaft 203 is fixedly installed at the transmission end of the left end of the driving motor 202, the anti-collision baffle 204 is fixedly installed at the left end of the transmission shaft 203, and the threaded rod 205 is fixedly installed at the left end of the anti-collision baffle 204.

[0026] Working principle: When it is necessary to process the composite surface of the aluminum alloy heat sink, firstly, the composite surface treatment device of the aluminum alloy heat sink is stably placed at the position where it is needed through the support legs 105 and the placement feet 106, and the aluminum alloy heat sink is placed on the placement plate 209, and the hydraulic cylinder 212 is started to adjust the length of the hydraulic push rod 213, so that it pushes the clamping plate 214 to clamp and fix the aluminum alloy heat sink, so that it is located under the working part of the chemical polishing machine body 102, and then the polishing liquid composed of a reasonably proportioned corrosive agent, an oxidant, and an additive is injected into the chemical polishing machine body 102, and then the aluminum alloy heat sink is sprayed, so that a series of chemical reactions occur under the action of the polishing liquid, and the microscopic uneven oxide film on the surface of the heat sink or The viscous mucous film formed in the polishing liquid corrodes and reduces the micro-roughness of the surface, thereby making the surface of the heat sink smooth and bright and improving the processing efficiency. Then, the drive motor 202 is started to rotate the transmission shaft 203, so that the transmission shaft 203 drives the threaded rod 205 to rotate, and the limit nut 207 moves from left to right on the threaded rod 205 and moves to the bottom of the air-cooled spray machine body 103. The air-cooled spray machine body 103 is used to spray it. The air-cooled spray machine body 103 uses compressed air flow to create negative pressure at the paint outlet. The paint automatically flows out and is fully atomized under the impact and mixing of the compressed air flow. The paint mist is ejected onto the surface of the workpiece under the push of the air flow and deposited. When the paint output is uniform and constant, the larger the air volume, the finer the paint atomization. A layer of 70μm thick radiation heat dissipation coating is sprayed on the surface of the sample after surface treatment by cold spraying process. The coating film is uniform and single. The coating is made of base material and binder in a ratio of 20:1. It can not only increase the radiation capacity of the material surface, but also has good self-cleaning property and improve the heat dissipation efficiency. Later, the aluminum alloy heat sink is removed, and the surface temperature of the sample is measured by thermocouple. The emissivity input value of the infrared thermal imager is continuously changed until the measured temperature average is equal to the thermocouple test temperature. The current emissivity value can be considered as the emissivity of the sample surface. The influence of surface treatment on the heat dissipation performance of the CPU is measured, thereby measuring the emissivity after treatment.
