Description
Technical field
The invention belongs to electric heater technical field, be specifically related to a kind of PTC heater.
Background technology
Aforesaid PTC heater is ptc heater, and PTC is English abbreviation (English: Positive Temperature Coefficient).Heater is formed primarily of following four parts: one is heater, and this heater also claims radiator; Two is PTC heat generating core; Three is tailstock; Four is electrical connection supporting seat.Heater comprise aluminum pipe and be positioned at aluminum pipe length direction on be surface and/or downside surface and in the radiating aluminium sheet of corrugated configuration.PTC heat generating core is contained in the tube chamber of the aluminum pipe of heater, comprise plural number piece neat arrangement and corresponding both sides surface with vacuum coating mode or with other similar mode be combined with electrode layer PTC thermistor (ceramic positive temperature coefficient thermistor) and be arranged on PTC thermistor both sides with each one piece of electrode slice (also claiming to be electrically connected bar, as follows) of electrode tube electrical contact.Heater is fixed (fixing with tailstock to insert embedding mode) together with one end of PTC heat generating core and tailstock, and heater is fixed with electrical connection supporting seat (to insert embedding mode and to be electrically connected supporting seat and to fix) together with the other end of PTC heat generating core.Aforesaid electrode slice (a pair) is being connected with the power-supply controller of electric electrical control of outside after electrical connection supporting seat by circuit.Under the control of power-supply controller of electric, such as, when being energized to electrode slice, PTC themistor is generated heat and is transferred heat to the aluminum pipe of heater, and the heat of aluminum pipe is distributed by radiating aluminium sheet.
The heater of said structure form is widely used in air-conditioning particularly hanging air conditioner or similar device, and be no lack of in disclosed Chinese patent literature and be seen in, slightly with " composite type PTC heater ", " a kind of heat-conducting aluminium pipe of PTC heater and the PTE heating element " of CN201499328U introduction and " PTC heater " of CN2392334Y disclosure that " the PTC heater external member " as CN2640002Y recommendation that exemplify, CN2753090Y provide, etc.
In order to ensure safety, set temperature controller and temperature fuse on the circuit be connected with electrode slice usually, and temperature controller and temperature fuse are arranged in above mentioned electrical connection supporting seat.In view of this, when making electrical connection supporting seat, electrical connection supporting seat is configured with temperature controller installation position (i.e. temperature controller installation cavity) and temperature fuse installation position (i.e. temperature fuse installation cavity), to this, " the heater hold-down support " of " a kind of ptc heater supporting seat and the ptc heater " that can disclose see Chinese utility model patent Authorization Notice No. CN201515508U and CN2402093Y bulletin.
Disclosed in above-mentioned CN2402093Y and CN201515508U, being electrically connected supporting seat, (CN2402093Y is called " heater hold-down support ", CN201515508U is called " ptc heater supporting seat ") although the technique effect stated clearly in its specification technique effect hurdle all can be embodied, such as can see the 0013rd section, the specification of CN201515508U, but there is following logical fraud: one, owing to temperature controller installation position and temperature fuse installation position being formed in electrical connection supporting seat pedestal, thus being arranged on the temperature controller in temperature controller installation position and being arranged on temperature fuse in temperature fuse installation position can only perception built-in temperature (so-called built-in temperature refers to the aluminum pipe temperature of heater), and cannot temperature beyond perception aluminum pipe, so when run into such as building fire occur just at first to cause indoor temperature rise sharply and run into cause because of the electric short circuit of air conditioner air conditioner external temperature rise sharply so that situation close to the critical temperature and so on of air conditioner burn time, because temperature controller and temperature fuse cannot perception and still make air conditioner in running order, thus serve the effect of adding fuel to the flames of unnecessary aggravation potential safety hazard, they are two years old, because the pedestal lid forming electrical connection supporting seat is lost rationally with the structure of electrical connection supporting seat pedestal, thus by means of securing member as both are fixed (can see the 0020th section, the specification of CN201515508U) by screw, thus efficiency of assembling need be affected when both being assembled, they are three years old, due to the unreasonable structure of electrical connection supporting seat pedestal, thus self-electrode sheet can only implement socket connection towards one end of electrical connection supporting seat pedestal in electrical connection supporting seat pedestal, so there is electrical connection loose contact, the situation of the especially easy ablation of plugging position when big current (as the electric current that fault causes) (to this can see the Instructions Page 3 of CN2402093Y and accompanying drawing thereof), its four, owing to lacking the measure circuit of being drawn by temperature controller and temperature fuse being implemented to reliable location, thus there is the situation of anti-pull fragility, and lose the clean effect of line arrangement.
In view of above-mentioned prior art, be necessary rational modification in addition, the applicant has done effective exploration repeatedly and design lastingly for this reason, finally technical scheme described below is defined, and taking under secrecy provision, carried out analogue test in the laboratory (test cabinet of holding concurrently) of the applicant, result has shockingly showed and the beyond thought technique effect comprehensively being made up aforementioned technical problem.
