High-efficiency heating module applied to hair dryer

A high-efficiency heating module applied to a hair dryer, comprising a shell body with two run-through ends, an insulation bracket mounted in the shell body, and a heating main body fixedly mounted on the insulation bracket, wherein the heating main body comprises a heat conduction portion and a heating portion;

• the heat conduction portion comprises a heat radiation inner cylinder, at least one layer of honeycomb-shaped heat radiation plate enclosed on an outer side of the heat radiation inner cylinder, and an outer heat radiation plate enclosed outside the outermost layer of honeycomb-shaped heat radiation plate;
• the heating portion comprises a first heating film and a second heating film;
• the first heating film is sandwiched between the heat radiation inner cylinder and the honeycomb-shaped heat radiation plate, and the second heating film is sandwiched between the outer heat radiation plate and the honeycomb-shaped heat radiation plate;
• first heat radiation fins are uniformly arranged on an inner side of the heat radiation inner cylinder and an outer side of the outer heat radiation plate;
• two enclosed portions of the outer heat radiation plate have locking edges;
• the outer heat radiation plate is enclosed and locked by the two locking edges;
• the honeycomb-shaped heat radiation plate is limited between the outer heat radiation plate and the heat radiation inner cylinder;
• each honeycomb-shaped heat radiation plate comprises a first heat radiation plate and a second heat radiation plate that are spaced apart from each other;
• second heat radiation fins are uniformly arranged between the first heat radiation plate and the second heat radiation plate;
• coupling edges are arranged on two enclosed portions of the first heat radiation plate and the second heat radiation plate;
• and after being enclosed, the first heat radiation plate and the second heat radiation plate resist against and are coupled with each other through the coupling edges.
