Radiator and central processing unit with same

Technical Field

The invention belongs to the technical field of radiators, and particularly relates to a radiator and a central processing unit with the radiator.

Background

In recent years, with the trend of miniaturization, high functionality and high frequency of computer cpus, the heat dissipated per unit volume is becoming higher and higher, and therefore the issue of electronic heat dissipation is becoming more and more important. In order to prevent the heat accumulation from causing over-high temperature and damaging the cpu, a heat sink is usually added, and a fan is used to force air convection to increase the heat transfer.

So far, the basic means for effectively preventing the internal of the cpu chip from overheating due to excessive heat accumulation is to attach a metal heat sink with high thermal conductivity and high heat capacity to the surface of the chip, to lead out the heat generated inside the cpu to the fins of the heat sink in a heat conduction manner, and then to transfer the heat into the air flow to be carried away by the convection action between the fins and the ambient air. However, the heat productivity of the cpu chip is gradually improved along with the performance increase, so the conventional solution is to increase the volume of the heat sink correspondingly, but the heat dissipation of the cpu is the heat propagated in the heat sink solid in a diffusion manner, so that the heat dissipation of the cpu cannot be uniformly distributed to each fin, the fin in the middle region of the heat sink directly above the cpu obtains a higher heat flux density due to a shorter heat conduction path and a smaller heat resistance, and the fins in the two side regions have a longer heat conduction distance, so that the heat resistance of the heat spreading laterally is larger, that is, the heat dissipation and cooling tasks shared by the fins of the heat sink are uneven, which results in a problem of poor heat dissipation performance of the cpu.
