Abstract

The invention discloses a thermomagnetic convection type magnetic fluid convection heat exchange system belonging to the technical field of magnetic fluid and enhanced heat exchange. A heater is placed in the heating area in the closed pipeline driven by magnetic fluid convection. The magnetic poles are fixed on the outside of the closed pipeline driven by magnetic fluid convection on both sides of the heater. The heating zone is located on the side of the symmetrical center of the magnetic pole. Drive closed pipeline. In the closed pipeline driven by magnetic fluid convection, the flowing magnetic fluid continuously takes heat away from the heating area where the heater is located, and then the magnetic fluid flows through the radiator, and the radiator dissipates heat to external equipment, forming a thermomagnetic convection cycle flow; and maintain the unbalanced temperature distribution on both sides of the magnetic poles to ensure the circulation of the magnetic fluid. The base liquid of the magnetic fluid can be a high thermal conductivity liquid to further improve the efficiency of the heat exchange system. The invention has the characteristics of simple structure, small volume, no mechanical moving parts, no energy consumption, no noise and simple maintenance.

Description

technical field [0001] The invention belongs to the technical field of magnetic fluid and enhanced heat exchange, and particularly relates to the principle of thermomagnetic convection of magnetic fluid in a gradient magnetic field, with magnetic fluid as the medium, driven by a non-mechanical method, without energy consumption and forced by moving parts A thermomagnetic convection magnetic fluid convection heat exchange system for convective heat exchange. Background technique [0002] Forced convection heat transfer is a heat transfer method widely used in industry, which requires a mechanical pump to drive the flow of fluid in the heat exchanger. In some special fields, the use of mechanical pumps is limited due to reasons such as reliability, volume, noise, and energy consumption. The present invention uses magnetic fluid as a working medium and is driven by the principle of thermomagnetic convection of magnetic fluid, which can solve the problem of traditional forced co...
