Electric heating device

The utility model provides an electric heating device, which comprises electric heating elements and radiating fins, excluding a metal casing pipe. Each electric heating element comprises a positive electrode, an electric heating component and a negative electrode, and the electric heating component is positioned between the positive electrode and the negative electrode. The electric heating device provided by the utility model does not use an aluminum flat tube or a casing pipe in the prior art, saves the cost, reduces thermal resistance of the aluminum flat tube in the intermediate link, improves the efficiency of heat transfer, and increases the volume power density.
