The structure comprises a connection element, a radiating crust, a radiating fin, a transitional heat conducting plate, a carbon fiber heating body, a spring electrode and an insulation layer. The insulation layer, the transitional heat conducting plate and the radiating fin are respectively arranged between the radiating crust and the carbon fiber heating body whose both ends connect with the spring electrode and arranged in U shape from inner to outer. Both ends of the transitional heat conducting plate are directly connected with the radiating crust by the connection element. Compared with the prior art, the carbon fiber heater of the utility model has the characteristics of simple structure, long service life, high conversion efficiency of the electricity and the heat, broad operating temperature range, safe in use, etc, does not have the visible light in the operating process and is convenient in picking up the telephone.

Description

Carbon fiber heaters

1, technical field

The utility model relates to a kind of electrical heating elements, a kind of specifically carbon fiber heaters.

2, background technology

As everyone knows, the heater wire under the prior art mostly uses nichrome, molybdenum filament, tungsten filament or ptc material to do electric heating element.Reason owing to these thermo electric materials self inherent characteristic, in use exist many deficiencies, as the electric heating element that general nichrome material, molybdenum filament, tungsten filament material are made, easily oxidation of surface in the electric heating process, cause local overheating thus and be blown, useful life is short.Have visible light to exist in the process of electric heating simultaneously, so the heat efficiency is low; Easily decay and puncture of electrical heating power during ptc material uses, useful life is short, and the heat efficiency is low.Though above-mentioned thermo electric material has the application of broad, they but are difficult to be made into the anti-permanent and high electric heating element that does not influence its range of application again of the heat efficiency of use.

3, summary of the invention

The purpose of this utility model is at above weak point, provides that a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, does not have visible light in the course of work, connects convenient, the safe in utilization carbon fiber heaters of electricity.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of carbon fiber heaters, comprise connector, heat-dissipating casing, fin, transition heat-conducting plate, carbon fiber exothermic part, spring electrode and insulating barrier, it is characterized in that two ends connect spring electrode, take the shape of the letter U between the carbon fiber exothermic part and heat-dissipating casing that is provided with, are respectively arranged with insulating barrier, transition heat-conducting plate and fin from the inside to the outside, transition heat-conducting plate two ends directly are connected with heat-dissipating casing by connector.

Carbon fiber heaters of the present utility model is compared with prior art, have that simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, do not have visible light in the course of work, connect characteristics such as electricity is convenient, safe in utilization, this reality is except that above characteristics, and the utility model also comprises:

1, mechanism design is simple;

2, thermo-lag is little, quick heating, and heating temp is even;

3, electrical heating power is adjustable, 50 ℃-200 ℃ of surface Working Temperature, and surface heat power is at 2W/cm ²-5W/cm ²Between the rice;

4, the geometry range of variation is wide, therefore in actual application, can adopt standard or non-standard unit mode to use;

5, electric property is stable, and reliable, useful life is up to more than 5 years;

6, applied environment: can be applied in air heat of industry, agricultural, civil area or the like widely.

Thereby, the utlity model has excellent popularization use value.

4, description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is the structural representation of carbon fiber heaters;

Accompanying drawing 2 is the side structure schematic diagram of carbon fiber heaters.

5, embodiment

Explain below with reference to Figure of description carbon fiber heaters of the present utility model being done.

Carbon fiber heaters of the present utility model, its structure is by connector 1, heat-dissipating casing 2, fin 3, transition heat-conducting plate 4, carbon fiber exothermic part 5, spring electrode 6 and insulating barrier 7, it is characterized in that two ends connect spring electrode 6, take the shape of the letter U between the carbon fiber exothermic part 5 and heat-dissipating casing 2 that is provided with, are respectively arranged with insulating barrier 7, transition heat-conducting plate 4 and fin 3 from the inside to the outside, transition heat-conducting plate 4 two ends directly are connected with heat-dissipating casing 2 by connector 1.

When making the utility model, one section carbon fiber exothermic part 5 is curved U-shaped, and its two ends are connected with spring electrode 6, externally set gradually insulating barrier 7, transition heat-conducting plate 4, fin 3 and heat-dissipating casing 2 then, for transition heat-conducting plate 4 two ends, then directly be connected with heat-dissipating casing 2 by connector 1.

The spring electrode 6 that carbon fiber exothermic part 5 two ends are connected inserts power supply, and electric current forms the loop through spring electrode 6 and the carbon fiber exothermic part between it 5, can realize heating function of the present utility model.

Carbon fiber heaters of the present utility model, carbon fiber exothermic part 5 can adopt braiding, single or many after-combustion or carbon fiber bundle to make; The material of connector 1 can be metal material; Heat-dissipating casing 2, fin 3 and transition heat-conducting plate 4 adopt metal material to make; The material of insulating barrier 7 can be pottery, quartz or other nonmetallic materials, and processing and fabricating is very simple and convenient, gets final product processing and fabricating shown in the by specification accompanying drawing.

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
