Magnetomotive flexible circulation heat dissipation system and heat dissipation device

Abstract

The invention relates to a magnetomotive flexible circulation heat dissipation system and a heat dissipation device. The magnetomotive flexible circulation heat dissipation system comprises a fluid pipeline used for introducing a liquid metal fluid working medium, a plurality of metal coils and an electromagnetic pump, the multiple metal coils are arranged on the fluid pipeline in a sleeving manner at intervals, the electromagnetic pump is installed on the fluid pipeline, and the liquid metal fluid working medium comprises liquid metal added with magnetic particles or liquid alloy added with magnetic particles. According to the present invention, liquid metal is driven to circularly flow to dissipate heat under the action that an electrified conductor is stressed in a magnetic field, and a magnetic liquid metal working medium is pushed to circularly flow to dissipate heat by adopting a combined driving mode of the electromagnetic driving pump and the multi-stage coils, so that higher circulating driving capability is obtained; moreover, a rotating part carried by a traditional pump is not arranged, so that the reliability is high; meanwhile, the heat conductivity coefficient of liquid metal is far higher than that of liquid water, so that the heat transfer capacity and the heat dissipation effect of the system can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field related to heat dissipation, in particular to a magnetodynamic flexible circulation heat dissipation system and a heat dissipation device. Background technique [0002] A laser projector is a projection product that uses a laser beam to transmit a picture. Its core components include a laser projector (optical machine), lens, DLP board, speaker, etc. There are red, green and blue three-color lasers in the laser projector, among which components such as the laser light source and the DMD processing chip are the high-power key components of the laser projector. With the improvement of the brightness and resolution of laser projectors, how to effectively dissipate the heat generated by these key components, control their temperature within the allowable temperature range, and control the noise of the whole machine is becoming more and more important. Ordinary laser projectors mostly use forced air cooling with...

Problems solved by technology

In order to improve the cooling capacity of the liquid cooling system, in addition to increasing the heat dissipation area and increasing the circulation flow, we can only choose a working medium with a higher thermal conductivity; while the main working medium of the traditional liquid cooling system is deionized water, it is necessary to improve the cooling of the liquid cooling system. The ability can only increase the heat dissipation area and improve the circulation flow. In the case of limited space, it cannot effectively improve the heat dissipation capacity

At the same time, driving the water cycle requires the addition of rotating parts such as water pumps. Long-term use of rotating parts has reliability risks such as mechanical wear and tear.
