Description

Magnetofluid heat pipe power generation system

Technical Field

The utility model relates to an energy conversion technical field specifically is thermoelectric direct conversion, relates to heat pipe and magnetic current body electricity generation, especially relates to a magnetic current body heat pipe power generation system.

Background

Direct thermoelectric conversion, generally referred to as the "Seebeck effect" proposed by Seebeck, a german scientist, i.e. a temperature difference that can generate an electric potential, refers to the thermoelectric phenomenon that causes a voltage difference between two substances due to a temperature difference between two different electrical conductors or semiconductors. Therefore, one existing solution is to use the temperature difference between the heat source and the cold source to generate electricity by using the thermoelectric generation piece after the heat of the heat source is conducted out. Unlike the thermoelectric generation principle, faraday proposes "magnetic generation", i.e. electromagnetic induction: when a part of the conductor of the closed circuit makes the cutting magnetic induction line movement, current can be generated on the conductor. With the help of this principle, the utility model discloses an arrange the wire, make the magnetic current body heat pipe in-process produce the electric current.

The heat pipe is applied to the fields of heat dissipation and refrigeration due to the high-efficiency heat conduction capability of the heat pipe. The heat pipe is filled with a low-boiling point heat-conducting working medium. One end of the heat pipe is an evaporation section, the other end of the heat pipe is a condensation section, and a heat insulation section can be arranged between the evaporation section and the condensation section according to application requirements. In short, a heat pipe is a device for transferring heat from one end to the other end by using a phase change method of a working medium. The working principle of heat transfer of the heat pipe is as follows: (1) In the evaporation section, the liquid working medium absorbs heat to generate phase change, and the liquid is changed into gas; (2) The gas working medium carries latent heat of evaporation and flows to the condensation section through the central channel; (3) In the condensing section, the gas working medium meets condensation to release latent heat of vaporization and the gas is changed into liquid; (4) The liquid working medium in the condensation section flows back to the evaporation section under the action of capillary force, pipe wall or gravity. And (4) continuing repeating the processes from (1) to (4) to realize the cyclic heat transfer.

The magnetic fluid is a novel functional material and has the dual properties of a magnet and a fluid. The magnetohydrodynamic generation technology cuts magnetic induction lines by driving conductive fluid through a power generation channel, and generates induced electromotive force on electrodes. The conductive fluid can be divided into a high-temperature plasma gas magnetofluid and a liquid metal magnetofluid. The current coal-fired magnetohydrodynamic power generation technology is advanced and energy-saving, and easily-ionized substances are added into gas in a certain proportion, and the coal is heated to about 3000K to ionize the gas. The liquid metal magnetic fluid is prepared by mixing low-melting-point liquid metal (such as gallium, tin, mercury, etc.) into volatile low-boiling-point working fluid (such as toluene, ethane, water vapor, liquid ammonia, etc.) as conductive liquid. After boiling, the working medium with low boiling point contacts with the liquid metal and expands into bubbles, and the liquid metal is pushed to rapidly flow through the power generation channel like a multistage piston pump, so that electromotive force is generated. Therefore, it is necessary to develop a mhd heat pipe power generation system.
