Advantages of cast aluminum disc electric heaters

Advantages of cast aluminum disc electric heaters

1、 Technical field

The utility model relates to an electric heater, especially an electric heater used in packaging machinery.

2、 Background technology

Although electric heating plates have been around for a long time and have been continuously improved in design, to this day, existing electric heating plates still have some defects: due to the plate structure and single layer of electric heating tubes inside the electric heating plates, and the thin resistance wire, there are defects such as poor reliability, high failure rate, and short service life. For the existence of the aforementioned defects, many users continuously provide feedback and demand improvement as soon as possible.

3、 Invention Content

The utility model aims to solve the problems of poor reliability, high failure rate, and short service life existing in the existing technology.

In order to achieve the purpose of solving the above technology, the technical solution of this utility model is: a cast aluminum disc electric heater, which includes a shell body and a built-in electric heating body, characterized in that: a. the electric heating body is wound into at least two coils or more in a coil tube shape. b. The electric heater is disc shaped with a through hole in the middle. c. The electric heater is evenly distributed with screw holes. d. The electric heating pipes are wrapped and tied with aluminum wire.

e. The electric heating tube is made of copper.

4、 Structural features

The utility model provides a cast aluminum disc electric heater, which includes a shell body and a built-in electric heating body, characterized in that the electric heating body is wound into at least two coils or more in a disc tube shape. The electric heating body has been improved from a plate type to a disc tube shape with more than two coils, increasing the area, reducing the failure rate, greatly improving reliability, and service life.

1. A cast aluminum disc electric heater, comprising a shell body and a built-in electric heating body, characterized in that the electric heating body is wound into at least two coils or more in a disc tube shape.

2. A cast aluminum disc electric heater according to claim 1, characterized in that the electric heating tubes are wrapped and tied with aluminum wires.

3. A cast aluminum disc electric heater according to claim 1 or 2, characterized in that the electric heater is disc shaped with a through hole in the middle.

4. A cast aluminum disc electric heater according to claim 3, characterized in that screw holes are uniformly distributed on the electric heater.

5. A cast aluminum disc electric heater according to claim 3, characterized in that the electric heating tube is a copper tube.

5、 What distinguishes it from other technologies

Compared with existing technologies, this utility model has the following advantages and positive effects: 1. The electric heating body is improved from a plate type to a disc tube shape with more than two coils, which increases the area, reduces the failure rate, greatly improves reliability, and service life. 2. The electric heater is disc shaped with a through hole in the middle, with a simple and practical structure, and is easy to manufacture. 3. Using aluminum wire to surround and fix the electric heating tube, due to its softness, it adopts a surrounding and fixed structure form, which is easy to bundle and tie, does not cause positioning deviation, and does not rust.
