Description

Electromagnetic heating energy storage device

Technical field:

The utility model relates to a device that provides heat sources for heating systems, industrial hot air manufacturing devices, steam generators, etc., and has the function of storing heat energy.

Background technique:

Existing devices that provide heat sources for heating systems, industrial hot air manufacturing devices, steam generators, etc. include a furnace body, which is equipped with magnesia refractory materials, and is equipped with resistance wires in the furnace body. The heat is sent to the heat exchanger for heat exchange. Its disadvantage is that the energy storage material magnesia refractory is solid and cannot flow, resulting in uneven temperature in the furnace body and large heat consumption. In addition, heat exchange is performed through hot air, and the heat utilization rate is low. The wire is easily damaged.

Invention content:

The technical problem to be solved by the utility model is to provide an electromagnetic heating energy storage device with uniform heat conduction, high heat utilization rate and not easily damaged.

The above purpose is achieved in this way: it includes a tank body, a heat medium inlet at the top of the tank body, a heat medium outlet at the bottom of the tank body, an inner tank is provided in the tank body, and an insulating material layer is wrapped on the outer wall of the inner tank body. A high-temperature wire is wound, and a coil is installed in the liner. The inlet and outlet of the coil protrude from the upper and lower parts of the tank respectively. Several cooling fins are fixed on the outer wall of the coil in the liner. The space between is filled with molten salt.

An electromagnetic heating rod is connected to the outlet of the coil outside the tank, and the electromagnetic heating rod includes a casing, and an intermediate pipe connected with the outlet of the coil is arranged in the casing, and several cooling fins are fixed on the inner wall of the intermediate pipe , the outer surface of the intermediate pipe is wrapped with an insulating material layer, and the outer surface of the insulating material layer is wound with a high-temperature wire.

The utility model has the advantages of high thermal efficiency, high-temperature heated wires are separated from the heat medium material, high safety, and not easy to be damaged; since the molten salt undergoes a phase change when heated, the deformation heat can store heat energy in a large amount, and the temperature changes when the temperature reaches a certain value. It is liquid and has good fluidity, so the heat conduction is uniform and the heat utilization rate is high.
