Thermocouple is a tubular electric heating element, is a metal shell ( Including stainless steel, copper tube) Along the tube center axial uniform spiral electric thermal bonding wire ( Nickel, chromium, iron chromium alloy) The gap filling compaction with good thermal conductivity of insulating oxide magnesia, with silicone seal on both ends of the tube, the metal armoured electric heating element to heat the air, metal molds and all kinds of liquid. The main heating mode depend on convective heat transfer, radiation heat transfer as the auxiliary pole.
electric heating radiant tube by converting electrical energy into heat transfer, radiation light waves can be heat transfer in a variety of media. Is the main way of heat radiation, convection heat transfer is complementary.
