Abstract
The utility model introduces a temperature self-limiting PTC electric heating band, which is composed of two or more than two chemical fiber core wires, metal wires, and a PTC material, wherein, the metal wires are wound on the chemical fiber core wires and form a current loop with the PTC material. Because the novel structural feature of the utility model, the utility model has the advantages of good flexibility and toughness, and both the bending resistance and the tensile strength of the utility model are enhanced.
Description
The utility model relates to a kind of heating wire, particularly makes the self-temperature-limiting heating strip of heater with the ptc conductive polymer material.
Existing P TC self-temperature-limiting heating strip is to synthesize one with many wires, as conductive core line.The defective of this structure is that the conductive core line cross section is big, and pliability is poor, and then makes whole ribbon heater external diameter thick, causes the ribbon heater flexibility poor, can not be arbitrarily crooked.When bending experiment, the conductive core line that real silk constitutes very easily fractures.These defectives are restricted the range of application of PTC self-temperature-limiting heating strip.
In view of the deficiency that above-mentioned PTC limits warm heating wire to exist certainly, the purpose of this utility model is a kind of PTC self-temperature-limiting heating strip with good pliability, bending resistance folding endurance and tensile strength of development.
The utility model PTC self-temperature-limiting heating strip has following design feature: it is made of the heart yearn more than two or two, metal wire and ptc conductive polymer material, the heart yearn parallel arranged, metal wire is wound on the heart yearn, the ptc conductive polymer material is rolled in metal wire on the heart yearn that is wound with metal wire, forms current circuit with the ptc conductive polymer exothermic material of extrusion molding on heart yearn.After the metal wire energized on the heart yearn that is wound on chemical fibre material, electric current flows out from a wires, flows to another wires through the ptc conductive polymer material.Electric energy heats up the PTC exothermic material.Along with the rising of temperature, the resistance of ptc material also increases gradually.When temperature rises to certain when a bit, ptc material resistance increases to the blocking-up electric current, heats up this moment to stop.The ribbon heater heat conducts heat to the lower heated object of temperature, and to the temperature of heated object during near the ribbon heater temperature, heat transfer stops, and the electrical power that send the ribbon heater levels off to zero, thereby realizes that the limit temperature is conducted heat automatically.
Because the utility model is taked to make heart yearn with the chemical fibre more than two or two, make electrode with the metal wire that is wound on the heart yearn, do from the temperature control exothermic material with extrusion molding ptc conductive polymer material on core work and metal wire, make this ribbon heater except that having from the advantage of limit temperature with novel structure, also have good flexibility and toughness, its bending resistance folding endurance and tensile strength all strengthen greatly.Can be widely used in industry and civilian electric heating field.
Describe the utility model in detail below in conjunction with accompanying drawing:
Fig. 1 ribbon heater cross-sectional view
Fig. 2 vertical structure schematic diagram
This ribbon heater is made of chemical fibre heart yearn 1, metal wire 2 and ptc conductive polymer exothermic material 3.In the present embodiment, heart yearn adopts two, is wound with metal wire on the every heart yearn, extrusion molding ptc conductive polymer exothermic material on the heart yearn.The metal wire of coiling is a pair of electrodes on the heart yearn, constitutes current circuit with ptc material.Because adopt two heart yearns to make the heating wire skeleton, and make it present the bandlet shape, this structure makes the ribbon heater have good flexibility and toughness, has strengthened the bending resistance folding endurance and the tensile strength of PTC self-temperature-limiting heating strip greatly.
