The utility model has the advantages that: compared with the PTC (Positive Temperature Coefficient) heater or electric heating wire in the prior art, the energy consumption is reduced by 40% to 50% and the heat efficiency is increased; the air is heated by means of forced convection to rapidly raise the ambient temperature; the ceramic electric-heating film heater is an infrared radiation body with a high electric-heat radiation conversion efficiency, so that the convection air heated by the ceramic electric-heating film heater is soft, is not dry or odor and can supply heat and simultaneously achieve the effect of health improvement; the ceramic electric-heating film heater automatically keeps constant temperature, heats uniformly, doesn't need the open fire, is safe and reliable and has a long service life; and the ceramic electric-heating film heater is applied to the electric blowers, the air heaters and other heating systems and adopts the AC/DC working voltage ranging from 3 V to 380 V.

Description

Novel energy-conserving porous ceramic electrothermal film heater

Technical field

The utility model relates to technical field of electric appliances, a kind of specifically novel energy-conserving porous ceramic electrothermal film heater.

Background technology

Existing nickel filament heater has naked light, has potential safety hazard, and high-temperature oxydation opens circuit easily, and useful life is short; The infrared ray quartz ampoule is frangible, though and the PTC ceramic heater has solved the former problem owing to be subjected to structural constraint, its electricity-thermal conversion efficiency is low, and is big with electric energy consumption, leaded waits polluter or element.

The utility model content

The purpose of this utility model is that design a kind of novel structure, technology are simplified, cost is low, stable performance and the warm-air drier of long service life or the electrothermal film heater of similar applications.

The utility model novel energy-conserving porous ceramic electrothermal film heater comprises: porous (regular hexagon, square or other) ceramic matrix 1, ceramic matrix 1 profile are can circle or rectangle; It is the electrothermal film material 2 of heatable usefulness that ceramic matrix 1 surface scribbles energising, on the base stage of the two ends of Electric radiant Heating Film 2, Ohmic electrode is arranged, the Ohmic electrode of lead and Electric radiant Heating Film 2 linked to each other to be become lead-in wire 3 and draws, and ceramic matrix 1 plays the function of heat exchanger again both as the heat transfer carrier of Electric radiant Heating Film 2.

The advantage of the utility model novel energy-conserving porous ceramic electrothermal film heater is:

1, novel structure, reliable, good stability; Adopt the heating of porous ceramic surface (single or double) or inwall, the size in hole, shape equalization, distribute all with; When energising, the ceramic matrix heating, swelling stress, the strain of being heated and causing are even, do not produce stress and concentrate, and be indeformable, not crooked, reliable in structure, stability is superior; Simultaneously, the lead-in wire production method is flexible, can select common metal silk, stranded conductor, screw connection etc. for use;

2, efficiency of heating surface height, power saving, energy-conservation; Electric radiant Heating Film slurry and ceramic matrix are fired back face densification, even; The face heating of energising back also produces infrared radiation, and the heating heat density is big, and electricity-thermal energy conversion efficiency height is than PTC ceramic heater power saving 40%～50%;

3, temperature is even, stable performance, long service life; The used Electric radiant Heating Film of this utility model adopts the prescription and the manufacture craft of lean, and film thickness is even, and face non-uniform temperature degree is less than 10%; Electric radiant Heating Film combines extremely firmly with ceramic matrix behind high-temperature firing, and both heat couplings are good; The Electric radiant Heating Film acid-alkali-corrosive-resisting, high temperature resistant, can work below 500 ℃ for a long time, its stabling current is than the ceramic little 40%-50% of PTC, and is aging slow;

4, cost economy, manufacturing process is simple; Owing to adopted full ceramic heat mode, ceramic matrix is the heating carrier, is again heat exchange, heat transfer structure; Compare with ptc heater, directly saved heat exchange, heat transfer units such as aluminium ripple bar, reduced production cost; Simultaneously, do not need bonding PTC and aluminium ripple bar yet, the Electric radiant Heating Film slurry fire behind ceramic matrix heater, technology, production process are simplified greatly, the efficient height;

5, environmental protection; By SGS-CSTC Standards Technical Services CO., LTD. detects, and not leaded, mercury, cadmium, Cr VI, noxious substances such as PBB, PBDES meet European Union environmental protection instruction 2002/95/EC (ROHS) and 2002/96/EC (WEEE) requirement;

6, infra red radiation function; After testing, the utility model electrothermic film element also is a kind of infrared radiating body, and the wave spectrum scope of its infrared radiation can be absorbed by the body at 2500～13000nm; Convection current air texture after its heating is submissive, moist, does not emit bad smell, and reaches health-care effect in heating, is a kind of heating mode of health environment-friendly;

7, automatic constant-temperature, the flames of anger improves ambient temperature fast; The utility model has positive temperature coefficient (PTC) effect equally with heater members, can realize automatic constant-temperature; The heating environment temperature is to the not enough 4min of equilibrium temperature in normal working conditions;

8, operating voltage is wide, and the use field is wide; Under AC/DC3～380V voltage, all can work;

9, the utility model reference and meet standards such as GB 4706.1-2005, GB 4706.23-2007.
