2. Product Introduction:

Working Principle: 


       Frost-free refrigerator is not a real frost-free refrigerator. As a matter of fact, it has adopted the finned evaporator to hid the real evaporator. Through the fan, it sends cold air through the various air channels to various parts to achieve the purpose of cooling, It should be noted that each frost-free refrigerator has a mechanical or electronic defrosting system, when the compressor works after a period of time ( about 8 - 12 hours ) the surface of the fin evaporator will also frost, such as the middle part of the fin evaporator is provided with an electric heating wire and a bimetallic temperature control and temperature fuse, and when defrosting, the evaporator is heated by the electric heating wire to a certain temperature, the bimetallic temperature control is switched off after defrosting is finished, and refrigeration is resumed. The water formed by defrosting flows from the box to the water storage box at the bottom of the refrigerator through a water diversion pipe, and is automatically evaporated by heating.

3. Performance & Application:

        It is generally designed and developed for electric heating defrosting on various refrigeration equipment such as cold storage, refrigeration, display, island cabinet, etc. Due to the characteristics of high indoor humidity, low temperature, frequent cold and hot impact and the like when the refrigerating equipment works, on the basis of a tubular electric heating element, high-quality modified magnesium oxide is adopted as a filler, stainless steel is adopted as a shell, after the shrink tube is adopted, two terminals are pressed and sealed by special rubber, so that the electric heating tube can be normally used in the refrigerating equipment. And can bend any shape as desire by that user. It can be conveniently embedded on the fins of the air cooler and condenser and the chassis of the water accumulation tray for defrosting. 

       The performance of the product has been proved by more than twenty years of practice, it is generally equipped with: 

(1). good defrosting effect; 

(2). stable electrical performance; 

(3). high insulation resistance; 

(4). corrosion resistance and ageing resistance; 

(5). strong overload capacity; 

(6). small leakage current;

(7). stable and reliable; 

(8). Long service life and so forth.

4. Technical Data:

  • the moisture insulation resistance of 200 m Ω or higher.

  • the resistance value can get to 30 m Ω or higher after the damp heat test insulation.

  • tidal leakage current is no more than 0.1 mA.

  • surface load: no more than 3.5W/cm² or less.

  • working temperature is 150 ℃. ( up to 300℃).

5. Product Advantages:

1). Mainly used in cooling fan, refrigerator, freezer and other refrigeration equipment.

2). good insulation and water resistance.

3). good corrosion with stainless steel 304 as the outer tube material.

4). generally use oven moisture treatment, color is beige, can be high temperature annealing treatment, electric heating tube surface color is black or dark green.
