Description
Technical Field
The invention relates to the field of electric heaters, in particular to a novel electric heater.
Background
The electric heater includes three kinds of forms such as convection type, energy storage formula and microcirculation: the convection type electric heater adopts the electric heating tube as a heating element, heats through heating convection of air, and has the advantages of small volume, quick start, quick temperature rise, accurate control and simple and convenient installation and maintenance; the energy storage type electric heater adopts energy storage materials, can store energy when the electricity price is lower at night and release heat in the daytime, but has larger volume and poorer heating comfort; the microcirculation electric heater is a novel electric heater which utilizes a heat-conducting medium filled in a radiator and utilizes the circulation of the medium in the radiator to improve the indoor temperature, the operation is reliable, and the heating efficiency is higher. Of the three types of electric heaters, the convection type electric heater is most commonly used, and almost all the civil electric heaters commonly seen in household electrical appliances are of the convection type.
The convection type electric heater utilizes the aerodynamic principle to cause the heating to be naturally convected from bottom to top. The convection type electric heater cover is provided with an air outlet and an air inlet below, air around the electric heating tube is heated and ascended after being electrified and flows out of the air outlet, and cold air around the electric heating tube enters and is supplemented from the air inlet. The above-mentioned processes are repeated so as to raise indoor temp. However, this method relying on natural convection of air has a limited acceleration of indoor air circulation, and cannot rapidly increase the indoor temperature.
And can fill the filler between the electric core in the electric heater pipe of electric heater and the shell, this is because the shell and the electric core of metal are uninsulated, and the filler closely fills can play the insulating effect in heating wire and tub of shell clearance position, and electric heating pipe's body is uncharged during the circular telegram, uses safe and reliable, and the filler generally needs to possess following characteristic:
1. the filler has sufficient insulativity and electrical strength, the metal shell and the electric heating core are not insulated, the filler is tightly filled in the gap between the electric heating wire and the tube shell to play an insulating role and also play a role in heat preservation and heat storage, and the shell of the electric heating tube is not electrified when electrified, so that the use is safe and reliable;
2. the heat conducting sleeve has good heat conductivity, and can timely transmit heat generated by electrifying and generating the carbon fiber heating wire to the protective sleeve;
3. the filler has high heat resistance and an expansion coefficient close to that of the electric heating core, and limits the displacement of the carbon fiber heating wire in the manufacturing procedures of shrinkage, annealing and bending of the electric heating tube;
4. the filler has higher mechanical property and temperature extreme change resistance, and can protect the electric heating wire from external mechanical pressure and impact; the pipe wall cannot be bulged and burst due to over expansion caused by sudden temperature rise in a short time, such as: the temperature of the electric heating pipe of the mold can rise to 3-4 hundred degrees instantly after being electrified for tens of seconds or even several seconds;
5. the filler has chemical inertia to the electric heating wire, and cannot generate chemical reaction with the electric heating wire to influence the characteristics of the electric heating wire;
6. the volume weight is small, and after the electric heating pipe is filled, the electric heating pipe cannot be too heavy;
7. the moisture absorption is small, so that even if the seal is polluted, the filler can not absorb a large amount of moisture in a short time when contacting air, thereby generating an electric leakage phenomenon or generating a tube burst phenomenon because the moisture is evaporated into air due to thermal expansion and cold contraction and the air is heated and expanded;
8. the material source is wide, the price is low, and the production and use cost of the electric heating tube is reduced.
However, the general inorganic composite filler has too large volume weight, and the heating pipe is too heavy after being filled, or has low thermal conductivity and poor thermal conductivity, and the thermal conductivity and low density of the inorganic composite material cannot be obtained at the same time, so that the requirement of the heating pipe filler cannot be met.
