Problems solved by technology

[0002] The frosting phenomenon not only affects the transparency of the glass of the refrigerated display cabinet, but also the door and window glass is easy to freeze, which makes it inconvenient to store and take out food, so the display cabinet and refrigerator must be equipped with a defrosting heater
Due to the characteristics of high indoor humidity, low temperature, and frequent cold and heat shocks when the refrigeration equipment is working, the technical performance requirements for the defrosting heater are particularly high. The main heating element of the existing heater in the market is an electric heating tube, while ordinary electric Tubes are easily damaged and have a short lifespan under low temperature and high humidity working conditions in display cabinets and refrigerators

Abstract

The invention discloses a heating pipe for defrosting, which comprises a pipe body, wherein an electric heating wire is arranged in the pipe body, both ends of the pipe body are fixedly connected with an insulating layer, the insulating layer is connected with conducting wires, the material of the pipe body is an aluminum foil, a clearance in the pipe of the pipe body is filled with compacted magnesia sand, the material of the electric heating wire is ferrochromium, the pipe body is designed into an E shape, and the number of the conducting wires is 3. The structure is simple. The aluminum foil pipe body has very good adaptability under the conditions of low temperature and high humidity, and the insulation resistance of the low-temperature state of a pipe-shaped electric heating element is enhanced by filling the compacted magnesia sand. Meanwhile, leakage current at a low-temperature state is lowered, and the E-shaped pipe body which is exclusively arranged can be inlaid on the fins of an air cooler and a condenser and at a chassis of a water accumulating disk more conveniently for defrosting.

Description

technical field [0001] The invention relates to an electric heating tube, in particular to a defrosting heating tube applied to freezing equipment such as freezing and refrigerating display cabinets and household refrigerators. Background technique [0002] The frosting phenomenon not only affects the transparency of the glass of the refrigerated display cabinet, but also the door and window glass is easy to freeze, which makes it inconvenient to store and take out food. Therefore, the display cabinet and refrigerator must be equipped with defrosting heaters. Due to the characteristics of high indoor humidity, low temperature and frequent cold and heat shocks when the refrigeration equipment is working, the technical performance requirements of the defrosting heater are particularly high. The main heating element of the existing heater in the market is an electric heating tube, while the ordinary electric Tubes are easily damaged and have a short lifespan under low temperatu...
