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 mainly made up 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 radiating aluminium sheet surface and/or downside surface and that be corrugated structure.PTC heat generating core is contained in the tube chamber of aluminum pipe of heater, comprise plural number piece neat arrangement and be combined with the PTC thermistor (ceramic positive temperature coefficient thermistor) of electrode layer and be arranged on PTC thermistor both sides and each one piece of electrode slice electrode tube electrical contact (also claiming electrical connection bar, as follows) in vacuum coating mode or in other similar mode on the surface of corresponding both sides.Heater is fixed (fixing to insert embedding mode and tailstock) together with one end and the tailstock of PTC heat generating core, and heater is fixed (fixing with electrical connection supporting seat to insert embedding mode) together with the other end of PTC heat generating core with electrical connection supporting seat.Aforesaid electrode slice (a pair of) is being connected with outside power-supply controller of electric electrical control after electrical connection supporting seat by circuit.Under the control of power-supply controller of electric, for example, while energising 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 be widely used in air-conditioning particularly hanging air conditioner or similarly device, and be no lack of and be seen in disclosed Chinese patent literature, " PTC heater " that " the composite type PTC heater " slightly providing with " the PTC heater external member ", the CN2753090Y that recommend as CN2640002Y that exemplify, " a kind of heat-conducting aluminium pipe of PTC heater and the PTE heating element " that CN201499328U introduces and CN2392334Y disclose, etc.
In order to ensure safety, set temperature controller and temperature fuse on the circuit being connected with electrode slice conventionally, and temperature controller and temperature fuse are arranged in above mentioned electrical connection supporting seat.In view of this, in the time making electrical connection supporting seat, on electrical connection supporting seat, form and have temperature controller installation position (being temperature controller installation cavity) and temperature fuse installation position (being 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 referring to Chinese utility model patent Granted publication CN201515508U and CN2402093Y bulletin.
By above-mentioned CN2402093Y and the disclosed electrical connection supporting seat of CN201515508U, (CN2402093Y is called " heater hold-down support ", CN201515508U is called " ptc heater supporting seat ") although all can embody the technique effect stating clearly in its specification technique effect hurdle, for example can be referring to the 0013rd section, the specification of CN201515508U, but there is following logical fraud: one, due to temperature controller installation position and temperature fuse installation position are formed in electrical connection supporting seat pedestal, thereby be arranged on the temperature controller in temperature controller installation position and be 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 temperature beyond cannot perception aluminum pipe, so there is just at first to cause indoor temperature such as building fire and rise sharply and run into when causing air conditioner external temperature and rise sharply and even approach the situation the critical temperature of air conditioner heating burning because of the electric short circuit of air conditioner when running into, because temperature controller and temperature fuse cannot perception still make air conditioner in running order, thereby play the effect of adding fuel to the flames of unnecessary aggravation potential safety hazard, they are two years old, because the pedestal lid that forms electrical connection supporting seat is lost rationally with the structure of electrical connection supporting seat pedestal, thereby need both be fixed to (can referring to the 0020th section, the specification of CN201515508U) as screw by means of securing member in the time that both are assembled, thereby affect efficiency of assembling, they are three years old, due to the unreasonable structure of electrical connection supporting seat pedestal, thereby self-electrode sheet can only be implemented socket connection towards one end of electrical connection supporting seat pedestal in electrical connection supporting seat pedestal, so there is electrical connection loose contact, especially the situation of the easy ablation of plugging position (to this can referring to the Instructions Page 3 of CN2402093Y and accompanying drawing thereof) when large electric current (electric current causing as fault), its four, owing to lacking the measure of the circuit of being drawn by temperature controller and temperature fuse being implemented to reliable location, thereby there is the situation of anti-pull fragility, and lose the clean and tidy effect of line arrangement.
In view of above-mentioned prior art, be necessary rational modification in addition, the applicant has done repeatedly to explore and design lastingly and effectively for this reason, finally formed technical scheme described below, and taking under secrecy provision, carried out analogue test in the applicant's laboratory (test cabinet of holding concurrently), result has shockingly showed and the beyond thought technique effect that is comprehensively made up aforementioned technical problem.
