CPU (central processing unit) integrated heating pipe radiator structure

Abstract

The invention belongs to the technical field of computer radiation and particularly relates to a CPU (central processing unit) integrated heating pipe radiator structure. A rectangular cross-section condensation heating pipe is arranged above a flat plate evaporation heating pipe; the downside of the flat plate evaporation heating pipe is in direct contact with a heat source; fiber liquid absorbing core structures which are laminated are arranged in the flat plate evaporation heating pipe; a through hole supporting frame is arranged in the rectangular cross-section condensation heating pipe; radiating fins are arranged outside the rectangular cross-section condensation heating pipe and combine the flat plate evaporation heating pipe and the rectangular cross-section condensation heating pipe into a whole and communicate the flat plate evaporation heating pipe with the rectangular cross-section condensation heating pipe to form an inner passage type structure; the fiber liquid absorbing core structures are formed by arranging three cylindrical metal wires of which the circles are tangential to one another; a flowing passage is arranged between every two metal wires. The CPU integrated heating pipe radiator structure has the beneficial effects that due to the fact that the flat plate evaporation heating pipe is in direct contact with the heat source, the contact heat resistance is reduced, and the heat transfer power is high; a larger condensation area is obtained on the basis that steam is enabled to fully flow by the rectangular cross-section condensation heating pipe, and the heat transfer performance is high.

Description

technical field [0001] The invention belongs to the technical field of computer heat dissipation, and in particular relates to a CPU integrated heat pipe radiator structure. Background technique [0002] With the continuous improvement of the CPU integration and performance of personal computers, the power consumption of the CPU is increasing, and the heat flux on the surface of the CPU increases sharply, which reduces the performance and life of the chip, and affects the reliability of the system operation. At the same time, very high requirements have been put forward for the CPU cooling method, which has caused many changes in the cooling method. Traditional methods of cooling CPUs typically employ aluminum extruded heatsinks, which offer advantages in terms of unit cost, weight, and performance. However, as computers develop toward compactness, the cooling performance of radiators is limited. At present, aluminum extruded radiators have tended to the limit of heat trans...
