technical field [0001] The invention relates to a heat dissipation device, in particular to a spiral fractal-based integrated miniature flat heat pipe designed to improve heat exchange performance. Background technique [0002] In recent years, with the rapid development of aerospace technology, information engineering, energy chemical industry, microelectronics technology, etc., the degree of integration of electronic circuits has been continuously improved, and the capacity of electronic components has been continuously expanded, and the resulting high heat flux density of electronic components become a major hidden danger affecting its normal work. The traditional heat dissipation method of simply using air forced convection cooling has reached the limit of heat transfer, and the heat dissipation problem has become the main bottleneck restricting the development of high heat flux optoelectronic chip technology and industry.

Problems solved by technology

[0004] The traditional micro-flat heat pipe manufacturing process is to design and manufacture the heat sink and the micro-flat heat pipe separately, and then apply thermal silica gel on the contact surface before attaching the micro-flat heat pipe to the bottom surface of the heat dissipation fin. The design is easy to process and manufacture, but such a design will undoubtedly increase the contact thermal resistance of the heat sink
