Sheath electric heater

HRY5Sheath electric heaterProduct Introduction

It is an electric heating device used to heat pipelines or their internal media. It consists of a microcontroller and a temperature sensor to form a temperature control unit, and also has two metal inner shells in the shape of bearing shells. There is an electric heating tube fixed on the inner wall surface of each metal inner shell; There are also two bearing shaped formed thermal conductive layers made of thermal conductive materials for fitting on the pipeline, and the outer wall surface of the formed thermal conductive layer is in contact with the inner wall surfaces of the two metal inner shells; It also has two bearing shell shaped insulation layers that are in contact with the outer walls of the two metal inner shells, and two bearing shell shaped outer shells are provided on the outer surfaces of the two formed insulation layers; It also serves as a fixed component for attaching the heating element to the pipeline. The present invention has the advantages of high thermal efficiency and convenient installation and disassembly, and is widely applicable to various pipeline heating occasions.

Electric heating is the process of converting electrical energy into thermal energy. Since the discovery that power can generate thermal effects through wires, many inventors around the world have been engaged in the research and manufacturing of various electric heating appliances. The development and widespread application of electric heating, like other industries, follows a pattern: it is gradually promoted from advanced countries to countries around the world; Gradually developing from urban areas to rural areas; From collective use to family, and then to individuals; The product has evolved from low-end to high-end.

Product comparison:
1. The heating of resistance heaters is the most primitive, so their thermal efficiency is also the worst, usually only about 70%, and a large amount of heat energy is emitted into the air.
2. Infrared heating is slightly better than resistance, but still emits a large amount of heat into the air. However, it is not the infrared itself that emits heat into the air, but rather the object being heated that emits heat into the air.
When the Feiru electromagnetic heater works, there is a layer of insulation that wraps around the heated object, and then the magnetic field passes through the insulation layer to directly heat the object itself, so the thermal efficiency is the highest with almost no loss of heat energy, and its thermal efficiency exceeds 95%. Moreover, since the Feiru electromagnetic heater generates heat from the heated object itself, there is no loss of heat transfer, resulting in an overall energy saving of about 30% -70% compared to resistance heating under the same conditions. Infrared heaters cannot be compared in detail with electromagnetic heating due to their heating characteristics, but based on the temperature emitted, Feiru electromagnetic heating should save more than 20% of energy compared to infrared heating under the same conditions.
