"plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected. Can also be detachably connected or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.

Referring to fig. 1-5, an electric heater heating body is applied to an electric heater, and includes a plurality of heat dissipation members, and a heating tube 3, wherein the heating tube 3 is disposed on the heat dissipation members.

The heat dissipation member is integrally formed and comprises a heat conduction plate 1 and fins 2. The middle part of the heat conducting plate 1 is provided with a pipeline 11 matched with the heating tube 3, and the heating tube 3 is respectively arranged in the pipeline 11. The fins 2 are of a sheet structure, which are vertically and spaced apart on both sides of the heat conductive plate 1. The heat generated by the heating tube 3 is transferred to the fins 2 through the heat conducting plate 1, and then is transferred to the air through the fins 2. Wherein, fin 2's length is the same, and fin 2's width is the same, and fin 2's height is decreased progressively to fin 2 far away from heating tube 3 by fin 2 near heating tube 3, makes the heat that fin 2 near heating tube 3 received more fully give off, and fin 2 far away from heating tube 3 simultaneously can reduce calorific loss.

The heat conducting plate 1 has two ends respectively provided with a convex strip 12 and a concave groove 13, as shown in fig. 4, the cross section of the convex strip 12 is circular, the cross section of the concave groove 13 is C-shaped, the convex strip 12 can enter the concave groove 13 through the end of the concave groove 13, or the convex strip 12 can forcibly enter the concave groove 13 through the notch of the concave groove 13. The two heat dissipating elements are connected with each other by sleeving the convex strips 12 with the grooves 13, and are rolled, as shown in fig. 5, so that the grooves 13 can tightly surround the convex strips 12, thereby realizing the fixed connection between the two heat dissipating elements. Meanwhile, the pipeline 11 can be jointed with the heating tube 3 by rolling, so that the heat conducting plate 1 can better absorb and transfer heat.

The heat dissipation piece is provided with a mounting opening 4 formed by stamping and used for mounting on the electric heater. After the heat dissipation member is connected, a process opening 41 formed by punching is arranged at the joint of the groove 13 and the convex strip 12, so that the connection between the groove 13 and the convex strip 12 is more stable.

The heat dissipation area of the fins which are closer to the heating tube is larger, so that the fins which are close to the heating tube improve the heat dissipation efficiency, and the fins which are far away from the heating tube reduce the heat loss rate, thereby improving the overall heat exchange efficiency and being beneficial to the electric heater to exert good heating effect; secondly, the utility model discloses can form by a plurality of heat-sink block built-up connection, improve the commonality widely, make its applicable electric heater in a plurality of models.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents, and all changes that can be made without inventive step are intended to be embraced therein.
