Abstract

The utility model discloses an electric heating tube, comprising a tube body and a tube core arranged in the tube body, wherein the outer side wall of the tube core is wound with a heating wire, and the winding density of the heating wire on the tube core increases axially at a rate of 1.12% per centimeter. The utility model can evenly heat the fan-shaped radiation range of the electric heating tube, maintain temperature balance, save energy, and thus greatly improve the heating performance of the heating plate.

Description

Heater

technical field

The utility model relates to the technical field of electric heating plate components, in particular to an electric heating tube.

Background technique

At present, electric heating plates are widely used in vulcanizing machines, which have the advantages of environmental protection and energy saving. Among them, electric heating tubes are important heating components. Traditional electric heating tubes are equipped with electric heating wires in the tube body, and their heat radiation range is uniform. However, in circular electric heating In the plate, the heat radiation range of the electric heating tube is fan-shaped, which cannot meet the requirements of fan-shaped heating uniformity.

Utility model content

The purpose of this utility model is to provide an electric heating tube to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: an electric heating tube, including a tube body and a tube core arranged in the tube body, the outer wall of the tube core is wound with a heating wire, and the heating wire The winding density on the die is increased axially at a rate of 1.12% per centimeter.

Compared with the prior art, the beneficial effect of the utility model is: an electric heating tube, the utility model can uniformly heat the fan surface radiation range of the electric heating tube, maintain the balance of the temperature, save energy, thereby greatly improving the temperature of the heating plate. heating performance.
