1. refrigerator defrost heating tube
Defrost heating tube is a kind of anti-freeze equipment commonly used in cold storage, freezers, display cabinets and other scenes. Its structure is composed of many small heating tubes, these defrost heaters are usually installed on the wall, ceiling or ground of the cold storage. During use, the heating tube emits heat, which increases the temperature of the air around the tube, thus avoiding frost and freezing in the cold storage.
The refrigerator defrost heater tube uses the principle of convection heating, that is, the air in the tube is heated by convection. Its advantage is that the heating speed is fast, the frost and ice in the cold storage can be quickly eliminated, and the heating tube is not easy to be limited by temperature, and can be installed anywhere in the cold storage. However, due to its large size and complex structure, installation and maintenance are more complicated.
Second, defrost wire heater
Defrost wire heater is a kind of single-wire heating equipment, which is usually used in some small refrigerators or household refrigerators. The heating wire is usually a 3.0mm silicone rubber heating wire, which is heated by electricity to raise the temperature of the surrounding air, thus eliminating frost in the refrigerator.
The defrost heating wire uses the principle of radiant heating, that is, radiating heat around through an electric hot wire. Its advantages are small size, simple structure, easy to install and maintain. However, the scope of the heating wire is small, can only be limited to a specific area of the refrigerator, the heating rate is slow, and the scope of application is relatively limited.
Third, the heating tube and heating wire comparison
In principle, the refrigerator defrost heater uses the principle of convection heating, and the heating wire uses the principle of radiation heating. From the structural characteristics, the heating tube is relatively complex, but its heating range is wider; The heating wire is simple in structure and small in size, which is suitable for small scenes. From the application scope, defrost heater tube is suitable for some large scenes, such as cold storage, freezer, etc. The heating wire is suitable for small scenarios, such as household refrigerators.
【 Conclusion 】
According to the above comparison, the difference between defrost heater tube and defrost heating wire mainly lies in their structure, principle and scope of application. Users should make the selection according to their actual needs, and consider the application scenario and environment of the device.
