Description

Ultra-thin high energy electric heater

The utility model relates to a kind of household electricity warmer, relates in particular to a kind of ultra-thin high energy electric heater, belongs to the electric-heating technology field.

Existing with the warmer of quartzy tubular electrothermal element as thermal source, be that resistance wire is arranged in the quartz ampoule, by imposing voltage, and convert electrical energy into heat energy at the resistance wire two ends, by reflector the heat energy reflection is added hot-air again, reach the purpose of warming.This warmer floor space is big, and the thermal efficiency (electric conversion efficiency) is low, heater element surface temperature height, poor stability.Also has a kind of electric heater that is referred to as electric heating installation using oil as medium, be by the tubular metal heating add the heat-sealing close in cavity oil or the material of water, heat is given to fin and passes to air, air heat is reached the purpose of heating, this electric heater structure is big, the thermal efficiency is low, and thermal inertia is big, and the temperature field is inhomogeneous, manufacturing cost is high.Above-mentioned electric heater consumes energy is many, result of use is undesirable, price is high, and security performance is not good enough, has brought inconvenience to the user.

The purpose of this utility model provides a kind of novel ultrathin high energy electric heater, and its cost is low, and is simple in structure, electricity-thermal conversion efficiency height, and security is good, diverse in function, life-span are long.

The purpose of this utility model is achieved through the following technical solutions, and a kind of ultra-thin high energy electric heater is characterized in that being made of electric hot plate and frame, and electric hot plate is superimposed successively hot-forming by insulating barrier, ornament, insulating barrier, carbon fiber electrically thermal element, insulating barrier; Frame is spliced into aluminium alloy extrusions, or is pressed into stainless sheet steel.

The utility model adopts carbon fiber electrothermal plate as heating, makes the electricity-thermal conversion efficiency height of electric heater, and thermal inertia is little, control (perseverance) temperature automatically, and simple in structure, cost is low, be easy to be accepted by wage-earners.

Accompanying drawing 1 is the utility model master TV structure schematic diagram;

Accompanying drawing 2 is the utility model side-looking structural portion view;

In the accompanying drawing, the 1st, carbon fiber electrothermal plate, the 2nd, frame, the 3,4, the 6th, insulating barrier, the 5th, ornament.

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is made of carbon fiber electrothermal plate 1, frame 2, insulating barrier 3,4,6 and ornament 5, and insulating barrier 6, ornament 5, insulating barrier 4, carbon fiber electrothermal plate 1 and insulating barrier 3 are superimposed successively hot-forming.Adopt the carbon fiber electrically hot material as heating, its core electric heating material is formed by carbon granules and epocel, utilizes the delicate balance acquisition temperature auto control between the insulating properties of the electric conductivity of carbon granules and epocel, reaches the purpose of economize on electricity.When the carbon fiber electrically thermal element of handling through surface insulation (plate) when two ends add voltage, the carbon granules that is dispersed in the epocel conducts electricity and the heat that has a resistance, resistance heat raises carbon fiber electrically thermal element (plate) temperature, and epocel expands, the distance of solid solution between carbon granules wherein increased, the electric current that passes through so just reduces, and has suppressed the rising of temperature, makes the surface temperature automatic constant-temperature of carbon fiber electrically thermal element (plate).Because electric current reduced when its temperature rose, so can reduce power consumption, reached energy-conservation effect.Simultaneously, when carbon fiber electrically thermal element (plate) heating power temperature raises, inspire far infrared, and the radiation wavelength of far infrared meets the coupling absorption approach, when promptly using carbon fiber electrically thermal element (plate) as warmer, heating target is people's skin and a clothing, and the emission wavelength of heating (plate) and the absorbing wavelength of skin and clothing are complementary, thereby have the highest heating efficiency.
