From the material point of view, electric heaters can be divided into many kinds. Cast copper electric heater is just one of them. It is an electric heater with a tubular electric heating element as the heating body and high-quality copper casting material as the shell and is die-casted. It can be widely used in plastic machinery, die head, cable machinery, chemical industry, rubber, petroleum and other equipment.
After practice, the operating temperature of the cast copper electric heater can reach between 150 and 600 degrees. In addition to a wide temperature range, the cast copper electric heater also has long life, good heat preservation performance, strong mechanical Anti-magnetic field and so on.
Because the cast copper electric heater is a high-efficiency heater with uniform heat distribution, the metal alloy with excellent thermal conductivity ensures the uniform temperature of the hot surface and eliminates the hot and cold spots of the equipment. Moreover, it also adds a thermal insulation device to the outer heat dissipation surface, and sinters infrared rays on the inner heat dissipation surface, so that the power saving effect is more obvious.
When using cast copper electric heaters, it is required that the working voltage should not exceed 10% of the rated value, the relative humidity of the air should not exceed 95%, and there should be no explosive and corrosive gases; its wiring should be placed outside the heating layer and insulation layer. , the shell should be effectively grounded, and at the same time avoid contact with corrosive, explosive media and moisture.
The whole cast copper electric heater should be placed in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours, and it can return to normal. Or reduce the voltage and energize until the insulation resistance is restored.
In addition, when using the cast copper electric heater, it should be well positioned and fixed, so that the effective heating area must be closely attached to the heating body, and empty burning is strictly prohibited; once dust or pollutants are found on the surface, it should be cleaned up in time. use, so as not to affect the heat dissipation and shorten the service life.
