Abstract

The invention discloses an impacted water cooling chip radiator with an imitated vegetation vein fractal micro-channel. The radiator comprises a shell composed of a circular baseboard, a cylindrical side wall and an annular top plate, wherein the baseboard is provided with a circular hollow part, and first-level, second-level, third-level and fourth-level grooves, the circular hollow part of the imitated vegetation vein fractal micro-channel is arranged at the centre of the baseboard, the first-level groove is symmetrically and radially arranged along the outer edge of the circular hollow part, each first-level groove is divided into two second-level grooves, each second-level groove is divided into two third-level grooves, each third-level groove is divided into two fourth-level grooves, the centre of the annular top plate is connected with a water inlet, and the periphery of the water inlet is uniformly provided with at least two water outlets which are connected with the annular top plate. The radiator is characterized in that the surface of the imitated vegetation vein fractal micro-channel is adopted, so that the fluid is better in flowing property, and the radiator is beneficial to improve the heat-sink thermal homogeneity and local high temperature of the micro-channel. The radiator is simple in structure, novel in principle and obvious in heat dissipation effect.

Description

technical field [0001] The invention relates to a chip radiator, in particular to an impact-type water-cooled radiator based on the bionic principle. Background technique [0002] According to Moore's Law, the number of transistors on an integrated circuit doubles every 18 months. On a tiny chip with the same area, the more integrated circuits, the higher the power consumption required and the greater the heat released at the same time. For chips with high heat flux density, if effective cooling measures are not taken, the stability and service life of the chips will be seriously affected. [0003] Bionics is a science based on imitating biological systems to construct corresponding technical systems, or making technical systems invented by humans have similar characteristics to biological systems. Bionics is the science of imitating living things. The combination of bionics and engineering technology forms the discipline of bionic engineering. The significance of bionic...
