Heater can be divided into direct and indirect heating heater two categories, commonly used in direct heating electric blanket, electric heating shoes, electric gloves and so on. Indirect heater (also known as space heater) with quartz heater, electric oil heater and heater and so on.
Electric oil heater by the metal tubular heating element, the metal wins hot film, conducting oil, Ju control book, power transfer switch and the universal ferry and other components. Its good security, large heat dissipation area, low surface temperature, mobile and flexible and so on.
Electric oil heater is in the cavity with a heat sink into the heat transfer oil. Electricity after the bottom of the horizontal heating tube. Heat conduction oil absorbs heat and circulates along the pipe in the cavity, radiating the heat to the space through the heat sink.
Electrothermal oil generally use bimetal control device to control the degree of fatness, its travel is to adjust the lever by rotating the pressure plate to heat the pressure of the metal plate to set the mud. After the setting is reached, the bimetal contacts are separated. Cut off the power.
Electric oil heater in use, the general controller will be transferred to the first high-Ju Yu block well power switch pots in the high-power position. And the temperature was raised. When the ambient temperature increased, and then low-power block protection Ju. Focus often hold electric oil heater can not heat or Ju degree is too high, too low fault repair.
