Abstract

The invention discloses a convective heat transferring system with thermomagnetic convection magnetic fluid, belonging to magnetic fluid and reinforced heat exchanging technology. Heater is set in the heating region in the closed pipe driven by magnetic fluid convection. Magnetic poles are fixed on the outside of the closed pipe driven by magnetic fluid convention at two sides of heater. The heating region is located at one side of the systemic center of magnetic pole and radiator is set on the closed pipe driven by magnetic fluid convection. In the closed pipe driven by magnetic fluid convention, flowing magnetic fluid carries the quantity of heat away from the heating region where the heater is set continuously and the magnetic fluid flows through the radiator. The radiator dissipates the quantity of heat to external equipment. thermomagnetic convection cycling flowing is formed. The unbalance of temperature distribution at two sides of magnetic pole is retained to ensure the cycling flowing of magnetic fluid. The basic liquid of magnetic fluid can be high thermal conduction liquid to improve the efficiency of heat exchanging system furthermore. The invention is provided with simple structure, small cubage, 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...
