Abstract

The invention discloses a nano magnetic fluid magnetic drive heat pipe. The heat pipe is provided with a magnetic circuit on one side of the evaporating section, and the heat source and the magnetic circuit are arranged oppositely, so that the fluid in the pipeline is subjected to the magnetic field while being subjected to the thermomagnetic action. The magnetic force generated by the gradient is driven to complete the cycle, and the gradient magnetic field is added through the permanent magnet. On the one hand, it avoids the power consumption of the electromagnet. Convective heat exchange, and use the characteristics of nanoparticles to assist nucleation to strengthen the nucleate boiling and condensation process, so as to realize the heat pipe designed with high heat flow and heat exchange capacity.

Description

【Technical field】 [0001] The invention belongs to the technical field of heat energy exchange, and relates to a nanometer magnetic fluid magnetic drive heat pipe. 【Background technique】 [0002] The heat pipes widely used at present are mainly siphon heat pipes and gravity heat pipes, also known as cored heat pipes and coreless heat pipes. In the evaporation section of the siphon heat pipe, the working liquid in the tube core is heated and evaporated, and the heat is taken away. The heat is the latent heat of evaporation of the working liquid. The steam flows from the central channel to the condensation section of the heat pipe, condenses into a liquid, and releases latent heat at the same time. Under the action of force, the liquid flows back to the evaporation section. In this way, a closed cycle is completed, thereby transferring a large amount of heat from the heating section to the heat dissipation section. For the gravity heat pipe, the reflux of the working liquid c...
