A tube-shaped or rod-shaped heating body is made of heat-proof porcelain with conducting filling particles or a conducting glass tube with high infrared emissivity and small resistance. The interior of the tube-shaped or rod-shaped heat body is respectively provided with two or more than two conducting heating electrodes at intervals along the axial direction or the cross section. The surface of the heating body is an insulating layer which is provided with glaze and is sintered. The utility model has the advantages of water prevention and insulation performances, good safety, long service life, low cost, uniform heat field, high conversion efficiency of electric heating, etc.
Description
Technical field
The utility model relates to a kind of conductive heating appts.
Background technology
Traditional hot-water heating mode provides low-temperature heat quantity by coal, gas firing mostly.Because the chemical energy in the fuel fails to utilize fully, thus exist huge waste, and discharge a large amount of CO during burning
2, SO
2With harmful substance such as dust, not only cause environmental pollution, and cause ecological destruction, as: greenhouse effect, acid rain etc.
Electric heat source is a kind of cleaning, the direct energy, along with the progress of nuclear energy, water-energy generating electricity, uses electric heating all to be of great importance to saving coal, gas resource and protection environment in a large number.
Existing electric heating mode mainly contains wire heating electric heater, air-conditioning, Electric radiant Heating Film, cable floor etc.The electric heater area of dissipation of wire heating is little, thermal field is inhomogeneous; Electric conversion efficiency is unsatisfactory; Wasted the energy; The thermal source of air-conditioning and ceiling Electric radiant Heating Film is mostly above the people, and the lta of hot-air own will be by convection on the pin and is not easy, so rate of energy is not high, and Electric radiant Heating Film is installed under the floor maintenance difficult, poor stability.
Summary of the invention
The purpose of this utility model can overcome the deficiency of prior art, but a kind of both conductive exothermals are provided, waterproof again insulation, and have the high conductive heater pipe of the heat efficiency.
Conductive heater pipe described in the utility model is by heat-stable ceramic that is mixed with the conductive fill particulate or infrared emittance height, and the less electro-conductive glass pipe of resistance is made tubulose or bar-shaped calandria; The outer surface of described tubulose or bar-shaped calandria is the high temperature resistant enamel sinter layer of one deck; In described tubulose or bar-shaped calandria, be arranged at intervals with two or more the conductive heater electrode of forming by metal or graphite material vertically; Described two or more conductive heater electrode also can be by the cross-sectional direction of tubulose or bar-shaped heating tube around being provided with in it at interval; Described two or more conductive heater electrode, interconnects with two poles by adjacent sequential successively all by extraction electrode.
Aforesaid conductive heater pipe, described conductive heater electrode can be to be embedded in the calandria inner structure, also can place the notch of opening on the calandria, the conductive layer that between electrode and calandria, has one deck to constitute by conducting resinl, conductive silver paste or conduction putty, notch is encapsulated by insulating material.
Aforesaid conductive heater pipe, described tubulose or bar-shaped calandria can be straight, crooked and special-shaped structure.
The utility model is compared with traditional electric heater unit, has following advantage and good effect:
1. the waterproof insulation performance is good, high safety.
2. electric conversion efficiency height.
3. the life-span is long, cost is low.
