The utility model has the advantages of good insulating performance, high safety, and beautiful appearance.
Description
The utility model relates to a kind of self-control thermostatic heat generating component, particularly a kind of safe positive temperature coefficient (PTC) thermistor heat generating component.
Positive temperature coefficient (PTC) thermistor material and the assembly thereof that with the barium titanate are host material at present are widely used in household electrical appliances air-conditioning and warmer or other warm braw equipment.In various types of PTC heat generating components, with adhered most widely used, market is maximum.This is because the manufacture craft of this heat generating component is simple, with low cost and radiating efficiency is high.But present this heat generating component generally all is that the PTC euthermic chip directly contacts with metal fin, with metal fin double as conductive electrode, so radiator integral is charged when work.Heating heat generating components as household electrical appliance is very unsafe like this.Moreover because the marginal portion of PTC chip is exposed, deterioration, aging takes place in the performance of assembly easily.Particularly under high humidity environments such as bathroom, not only this deterioration is more obvious, and can take place to puncture and burn even dangerous situation such as electric shock.In addition, for some special purposes,, the insulation characterisitic on the surface of heater there is strict requirement as the heating heat generating components on the train.Common adhered PTC heat generating component can't satisfy this requirement certainly.In order to solve the problem of insulation, a kind of method is to spray heat-resisting organic resin on the surface of heat generating component to reach the purpose of insulation.But the shortcoming of this method is that the organic resin on metal fin surface can influence radiating efficiency greatly, and life-span and reliability are all undesirable, especially can not satisfy the requirement of train with space heater.
The purpose of this utility model is exactly in order to address the above problem, and a kind of safe, energy-efficient and reliability and the good safe semistor heat generating component of anti-aging characteristic are provided.
Technical solution of the present utility model:
A kind of safe semistor heat generating component, it is made up of heating core and peripheral fin one, the core that it is characterized in that generating heat is made of PTC thermistor euthermic chip, upper and lower battery lead plate and surrounding layer, the upper and lower surface and the upper and lower battery lead plate of PTC thermistor euthermic chip closely are connected as a single entity, periphery at them is enclosed with heat-resistant insulating film, the periphery of heat-resistant insulating film integral body again is enclosed with the metal surrounding layer, the upper and lower surface of this metal surrounding layer and two fin are connected as a single entity, and form heat generating component.
The adhered PTC heat generating component of surface insulation when the utility model provides a kind of operating voltage to be 100 to 240V.This thermistor heat generating component is not only fool proof, energy-efficient, and has improved the reliability and the anti-aging characteristic of assembly greatly, can be widely used in all kinds of high-grade electricity heatings and firing equipment.
The utlity model has following advantage:
1, Totally-enclosed-type, dust and moisture, good insulation preformance, security reliability height are handsome in appearance.
2, technology reasonable in design simple, be easy to make, with low cost.
3, applicability is strong, can be widely used in from household electrical appliances to industrial various heating or heating system, and be particularly suitable for the warmer of special occasions such as train.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is a decomposition texture schematic diagram of the present utility model;
Fig. 3 is the A-A sectional schematic diagram of Fig. 2.
As Fig. 1-3, the utility model is made up of heating core 1 and peripheral fin 2 one, characteristics of the present utility model are that heating core 1 is made of PTC thermistor euthermic chip 3, upper and lower battery lead plate 4,5 and surrounding layer 6, the upper and lower surface of PTC thermistor euthermic chip 3 and upper and lower battery lead plate 4,5 closely are connected as a single entity, be enclosed with heat-resistant insulating film 7 in their periphery, the periphery of heat-resistant insulating film 7 integral body again is enclosed with metal surrounding layer 6, the upper and lower surface of this metal surrounding layer 6 and two fin 2 are connected as a single entity, and form heat generating component.
In the utility model, heat-resistant insulating film 7 should closely be wrapped in the outside of PTC thermistor euthermic chip 3 and upper and lower battery lead plate 4,5 thereof.
Connect with the heat conduction heatproof is gluing between heating core 1 of the present utility model and the metal fin 2.The upper and lower battery lead plate 4,5 of heating core 1 links to each other with heatproof lead 8.The metallic plate of surrounding layer 6 can be aluminium matter, copper or other metal material.The material of battery lead plate 4,5 is aluminium matter or copper preferably, is beneficial to heat-conductivity conducting.Can constitute the PTC heating unit assembly of good insulation preformance, safe and reliable, water proof and dust proof like this.
