Zusammenfassung:The utility model discloses a heat dissipation device for an air heater, which comprises a heat conduction pipe, an electric heating pipe assembly is inserted into the heat conduction pipe, a plurality of heat dissipation fins which are distributed from top to bottom are fixed on the outer walls of the left side and the right side of the heat conduction pipe, and the section of each heat dissipation fin is of a wave-shaped structure. A wave-shaped flow channel is formed between every two adjacent cooling fins located on the same side of the heat conduction pipe, and the flow channels are used for allowing air to flow through. After the radiating fins with the wave-shaped structures are adopted, a flow channel formed between every two adjacent radiating fins also forms a wave-shaped structure, so that when air flows through the flow channels, the contact area between the air and the radiating fins can be increased, the air can flow along a curve path, and the heat dissipation efficiency is improved. Therefore,
