Problems solved by technology

These two types of heaters have disadvantages such as low energy utilization rate, slow heating response speed, and short service life of resistance wire.
The above two types of heaters have low energy utilization rate and low heat transfer efficiency, so the temperature difference between the surface of the heated object and the surface of the resistance wire is too large, resulting in a short life of the resistance wire

Abstract

The invention discloses electric heating equipment. The heater is used for transmitting heat energy to a heated object. The electric heating device comprises an electric heating tube, the electric heating tube comprises a quartz tube, an electric heating body arranged in an inner cavity of the quartz tube and a heat conduction layer for fixing the electric heating tube to the surface of the objectto be heated, the heat conduction layer is composed of a plurality of heat conduction elements, a heat preservation layer is arranged outside the heat conduction layer, and the outer surfaces of theheat conduction elements comprise at least one protrusion which makes contact with the heat preservation layer.

Description

technical field [0001] The invention relates to a heating device, in particular to an electric heating device. Background technique [0002] The electric heating device is a device that consumes electric energy and converts it into heat energy to heat the materials to be heated. It is widely used in a variety of industrial production equipment. The typical use is to dry raw materials in the hopper of the injection molding machine. , or other drying equipment. Most of the existing heaters heat the tungsten wire and radiate the heat to the outside to achieve the purpose of heating. The thermal effect of this tungsten wire heater is low, and it often takes a lot of electric energy to achieve the required heating effect. In order to solve the problem of low efficiency conversion of tungsten wire heaters, another method is proposed in the prior art: using resistance wires to convert part of the electric energy into infrared radiation energy, and heating the heated object throug...
