Description
Technical field
The utility model relates to a kind of PTC thermistor, particularly a kind of PTC heating rod.
Background technology
At present, the electric heater using on market all adopts heating wire as main mode of heating, is subject to the impact of this body structure of heating wire and heating power, and heating wire can not directly be put into water and heat, if need the words of feedwater heating, heating wire outside needs sleeve pipe just can put into water, is subject to the impact of sleeve pipe heat radiation, and maximum heating power when heating wire is heated up water is lower, also lower to the heat conversion of electric energy, cost is high, and uses dangerously, is prone to naked light.
Simultaneously, heating wire only can be accomplished basic insulation at present, while using in I electric appliances, the conductive component easily touching and the protective earthing wire being arranged in fixed line need be coupled together, make the conductive component easily touching when basic insulation damages, not become electrified body, finished product design cost is higher; For the bad family of power utilization environment from far-off regions, the heating series products heating wire that need meet the requirement of II electric appliances reinforced insulation is completely inapplicable, is therefore necessary to design a kind of novel PTC heating rod, to overcome the problems referred to above.
Existing PTC constant temperature energy-saving heating rod, is comprised of PTC thermistor chip, false sheet, electrode slice, wire, sleeve pipe, silica gel; PTC thermistor chip, false sheet and both sides electrode slice adopt heat conductive silica gel bonding, and electrode slice connects and goes between and overlap with silica gel sleeve pipe, puts into circular aluminium bar and compresses mechanically.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of constant temp. warming, the flames of anger, efficient, safe, energy-conservation, not only can directly put into water and heat, and also can outer cover puts into the PTC heating rod that water heats after with sleeve pipe.
The implementation of the utility model object is, PTC heating rod, there is one or more layers arc groove in circular aluminium bar outside, inside there is one or more layers rectangular channel, one or more layers PTC heating component pierces into from one or more layers rectangular channel of circular aluminium bar, and is crimped in circular aluminium bar by one or more layers arc groove; Described PTC heat generating component has a plurality of side-by-side PTC thermistor chips and false sheet, each PTC thermistor chip and the both sides adhesion of false sheet have conductive electrode film, two electrode slice tail end riveted joint lead-in wires, insulating sleeve is sheathed on riveted joint position, the conductive electrode film outer wrapping insulating material of PTC thermistor chip, false sheet and both sides; One or more layers rectangular channel other end seals with plug.
Operation principle of the present utility model is after the energising of PTC thermistor chip, because self-heating causes component body temperature to rise, resistance value enters transition district, electric current declines rapidly, when heated at constant temperature PTC thermistor chip, its surperficial temperature also continues to keep steady state value, realizes the function of constant temp. warming; Heat dispels the heat by circular aluminium bar, can make it reach larger heating power, and the flames of anger occurs.
The utility model constant temp. warming, the flames of anger, efficient, safe, energy-conservation, not only can directly put into water and heat, and also can outer cover puts into water after with sleeve pipe and heat.
