Abstract

The invention discloses a combined tool, device and method for forming array structure fins. Combined tools include cutting tools and limiting tools. The cylindrical workpiece is processed by using the coulter and limiting block of the limiting tool and the cutting edge and rake face of the cutting tool; the coulter plows out multiple parallel continuous lines on the chips. Grooves, the material between the grooves accumulates to form fins on top of the chips, the cutting edge cuts out continuous chips, and the continuous fins are "accumulated-destroyed" in the compression area between the limiting block and the rake face The principle is to form a periodic wavy shape, and a three-dimensional structure of fins can be produced by combining tools. The device includes the above-mentioned combination tool and vibrator. The combination tool is driven to reciprocate and vibrate along the feed direction through the vibrator, so that the unstable self-excited vibration becomes stable forced vibration, shortens the period of the "accumulation-destruction" state of chips, and makes the wing The sheet molding cycle is relatively stable, and the fins are needle-shaped, with high heat transfer performance.

Description

technical field [0001] The invention relates to the technical field of fin manufacturing, in particular to a combined cutter, device and method for forming array-structured fins. Background technique [0002] Heat transfer technology is an important technology in the field of energy and power, especially with the continuous development of low-temperature processing technology and portable electronic devices, the demand for heat transfer performance in local spaces continues to increase. In the technical field of surface enhanced heat transfer, a variety of surface array structures including needle-like array structures have been proven to have excellent heat transfer performance. Compared with traditional smooth surfaces and grooved continuous fin surfaces, their heat transfer performance can be improved. Increased by more than 20%, and with the application of technologies such as enhanced convection, its advantages become more and more obvious. [0003] However, the curren...
