Abstract
The utility model discloses a positive temperature coefficient (PTC) heating sheet which comprises a PTC heating sheet, wherein the front side and the back side of the PTC heating sheet are provided with surface electrodes; two ends of the front side and the back side of the PTC heating sheet are provided with grooves; the grooves are provided with leads for electrically connecting the surface electrodes; when the PTC heating assembly is assembled, silver conductive adhesive and a metal conducting sheet are not used, thereby saving material cost; meanwhile, the two ends of the PTC heating sheet are provided with the grooves, and the leads are welded to the prefabricated groove through the added scaling powder; and the flat PTC heating sheet has high electric conducting and heat conducting efficiency.
Description
Technical field
The utility model relates to a kind of electrical heating elements technology, particularly relates to a kind of PTC heater element.
Background technology
Existing PTC heater element, by the PTC ceramic heating plate, 2 thermal conductive metal plates and 2 lead-in wires are formed, and described PTC ceramic heating plate is sandwiched between 2 thermal conductive metal plates.The assembly relation of this PTC ceramic heating plate and 2 thermal conductive metal plates is clamping connection relations, thereby, just producing the loose contact between PTC ceramic heating plate and thermal conductive metal plate inevitably, this not only influences its heating efficiency, but also can directly influence heat conductivility.
In order to address this problem, Chinese patent application 200820040874.X discloses a kind of PTC heater element, comprise the PTC ceramic heating plate, be laminated with upper and lower thermal conductive metal plate at described heating sheet positive and negative, 2 lead-in wires respectively at upper and lower thermal conductive metal plate electrical connection, with the high temperature insulation spare that is encapsulated in integral outer, between described heating sheet and upper and lower thermal conductive metal plate, be respectively equipped with silver slurry adhesive layer.This PTC heater element, be through bonding behind the high-temperature baking with stamping forming sheet metal with PTC heating sheet, lead is riveted on the sheet metal link then, because this PTC heater element need be used conductive silver paste, long-time high temperature makes conductive silver paste rotten, brings potential safety hazard, because the heat release of metallic conductor, reduce the efficient of heating, increased Financial cost.
Because the defective that above-mentioned existing P TC heater element exists, the design people is actively studied innovation, in the hope of founding a kind of PTC heater element of new structure, makes it have more practicality.
The utility model content
Main purpose of the present utility model is, overcome the defective that existing P TC heater element exists, and provide a kind of PTC heater element of new structure, technical problem to be solved is to make its structure simpler, heating efficiency and safe PTC heater element, thereby be suitable for practicality more, and have the value on the industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of PTC heating sheet that the utility model proposes, comprise PTC heating sheet, the positive and negative of described PTC heating sheet is provided with surface electrode, and the two ends of the positive and negative of described PTC heating sheet are provided with groove, are provided with the lead that is electrically connected surface electrode in the described groove.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid a kind of PTC heating sheet, wherein said lead is welded on the electrode by scaling powder, and the lead and the PTC that are arranged in the described groove generate heat sheet at grade, and the welding lead place is prefabricated fluted, make the surface of PTC heating sheet keep smooth, the heat transfer efficiency height
Aforesaid a kind of PTC heating sheet, wherein said wire bonds encapsulates by insulating sleeve in the outside of the tie point of electrode, and the integral outer that described PTC heating sheet is connected with lead is enclosed with the yellow paper of insulation, has guaranteed the electric insulation of PTC heating sheet.
Aforesaid a kind of PTC heating sheet, wherein said PTC is the quadrangle sheet, or rounded sheet, or sheet triangular in shape, also can be set to multiple shape.
By technique scheme, a kind of PTC heating of the utility model sheet has following advantage at least:
When assembling PTC heat generating component, do not use conductive silver glue and metallic conduction sheet, saved material cost, adopt two ends prefabricated groove simultaneously at PTC heating sheet, directly lead can be welded auxiliary agent by adding and be welded on the prefabricated groove place, smooth PTC heating sheet, conduction and heat transfer efficiency are higher.
In sum, a kind of PTC heating sheet of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
