Description

Technical Field

[0001] This invention relates to the field of radiator manufacturing, specifically to a composite processing equipment and method for finned radiator teeth and microstructures. Background Technology

[0002] By machining microstructured grooves on the surface of the fins in traditional finned radiators, the heat dissipation area can be effectively increased, greatly improving the radiator's heat dissipation performance. While traditional finned radiators can be manufactured using milling and gear-shaping methods, microstructure machining of the densely packed heat dissipation grooves on the fins presents certain challenges.

[0003] For example, Chinese patent CN204227973U discloses a heat pipe fin array radiator, including a lower base plate, an upper base plate, a support plate, and several thin-plate heat pipe fins. The upper surface of the lower base plate is machined with several channels, and the upper base plate is provided with several slots. The channels and slots correspond to each other and are arranged in an array. The bottom ends of the heat pipe fins are installed in the channels, and the top ends of the heat pipe fins pass through the slots. The support plate connects the lower base plate and the upper base plate, and the lower base plate is provided with an interface for connecting to electronic heating components. However, due to the limitations of the finned radiator structure, the heat dissipation grooves are located in a densely packed, tiny space. After the finned portion of the finned radiator is machined, it is difficult to machine the microstructure grooves on the fins.

[0004] Chinese patent CN216775347U discloses a length-adjustable stable radiator fin, including a base plate and an outer fin. A counterweight base is fixedly installed on the lower surface of the base plate, and a movable plate is movably installed inside the base plate. A deep groove corresponding to the movable plate is formed inside the base plate, and the inner wall of the base plate is in contact with the surface of the movable plate. It also includes an inner fin, which is movably installed inside the outer fin, with its end fixedly connected to the upper surface of the movable plate. A fixing block is fixedly connected to the upper surface of the inner fin. When the overall length of the adjustable stable radiator fin needs to be adjusted according to actual conditions, rotating the threaded rod on the surface of the base plate moves the movable plate outward from the deep groove. The inner fin moves along with the movable plate, increasing the distance from the left side of the outer fin to the right side of the inner fin, thus changing the overall length of the device. However, it still cannot achieve the processing of micro-structured grooves on the fin.

[0005] Because the fins are relatively thin and have relatively poor rigidity, and are densely packed within tiny spaces, it is difficult to further process the micro-grooves using conventional metal cutting methods after the fins of a finned radiator have been manufactured. Furthermore, to avoid compromising the overall performance of the fins, once grooves are created, their size must be designed to be very small, constituting micro-grooves, which are even more impossible to process using conventional metal cutting methods. Therefore, traditional equipment and methods for processing finned radiators are insufficient for the fin processing needs, posing a significant challenge to the industrialization of finned radiators. Summary of the Invention

[0006] To address the problem that existing radiator manufacturing devices and methods cannot perform microstructure processing on radiator fins, this application designs a composite processing equipment and method for finned radiator teeth and microstructures, aiming to achieve microstructure processing on the surface of finned radiators.

[0026] Step S1: Install the blank of the finned radiator on the worktable, and adjust the front and rear position of the worktable on the slide to make the shaving cutter be positioned at the center of the blank of the finned radiator.

Adjust the position of the finned heat sink blank on the equipment using the worktable to ensure that the laser processing equipment irradiates the surface of the finned heat sink blank at the optimal light output angle.

[0028] Step S3: After the microstructure processing of the finned radiator surface is completed, reset the position of the worktable to ensure the shaving tooth processing is carried out.

[0029] Step S4: After the fin tooth of one fin of the finned radiator is processed, repeat step 2.

[0030] Step S5: After the teeth and microstructure machining are completed, the excess parts of the part are removed by milling, and the part machining is completed.
