High-efficiency heat radiator for closed-structure high-heat flux device

Abstract

The invention provides a high-efficiency heat radiator for a closed-structure high-heat flux device, which comprises a liquid metal pipeline and heat radiation fins, wherein the liquid metal pipelinepasses through the heat radiation fins; and the liquid metal pipeline is filled with liquid metal capable of flowing. A driving pump is also included, and the driving pump is arranged on the liquid metal pipeline for driving the liquid metal in the liquid metal pipeline to flow. A liquid metal self-circulating cold plate is made by adopting a processing mode such as overall casting or welding, a heat absorption device, a heat radiation plate, the heat radiation fins and the liquid metal pipeline are integrated, the heat resistance of the system is reduced to the most extent, and the heat conduction efficiency is high; and the heat conductivity of the liquid metal is much higher than that of water, air and multiple non-metallic media, and thus, the liquid metal heat radiator can achieve more efficient heat transport and extreme heat radiation ability than traditional water cooling.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation, and in particular relates to a new high-efficiency radiator with low energy consumption, small volume and high reliability, which integrates liquid metal, a forced air cooling device, a driving pump and an integrated cold plate. Background technique [0002] At present, with the improvement of the functions of electronic equipment, the integration and heat flux density of its devices are also significantly improved. The simple use of forced air cooling can no longer meet the thermal design specifications, and the traditional liquid cooling solution needs to fix the heating device on the liquid cooling cold plate, and the heat can be effectively taken away by the liquid flow. However, the space constraints of secondary cooling equipment required by traditional liquid cooling often become its restrictive design factor, and it also brings about increased energy consumption at low temperatur...
