Defrosting heating tubes are basically conducting, but there are also non-conducting models, depending on the design and application of the specific product.
1. Characteristics and working principle of defrost heater tube
Defrost heating tube is a kind of electric heating device used for defrosting in cold storage, refrigeration equipment, air conditioning and other fields. Its shape is cylindrical, square tube or film strip shape, composed of resistance wire, insulating material and outer sheath.
The working principle of defrost heating tube is to use the resistance wire to generate heat, heat its surface, and transfer the generated heat to the surface of the pipe or equipment to raise its temperature and melt the frost or ice on it to achieve the purpose of defrost.
2. defrost tubular heater conducting characteristics and functions
Most defrost heating tubes are conductive because their resistance wires are made of materials such as copper-nickel alloy or iron-chrome-aluminum alloy, which have very small resistivity and good electrical conductivity. In addition, the surface of the conductor is covered with a layer of insulating material to ensure its safe and reliable operation.
Defrost tubular heater conducting conducting characteristics and functions are:
1. Good defrost effect: the defrost heater can release a large amount of heat and quickly increase the surface temperature of the equipment, so as to effectively defrost.
2. Prevent frost freezing: the defrost heater tube can also prevent frost freezing, so that the operation of refrigeration equipment is more stable and reliable.
3. the influencing factors of defrost tubular heater conducting
Whether defrost heater tube is conducting or not depends on its specific design and application range. Some defrosting heating tubes may use non-conductive materials to make resistance wires, and this defrosting heating tube is a non-conductive model, which is mainly suitable for some special environments, such as explosive and flammable places.
In addition, the factors that affect whether defrost heater tube conducting also include: power supply voltage, pipeline resistance, environmental temperature, etc. In the use of defrosting heating pipe, it is necessary to choose the appropriate type of conduction according to the specific situation, and ensure that it works safely and reliably.
