Abstract

The utility model relates to a braided carbon fiber infrared quartz heating tube which is arranged in an insulating outer shell; both ends of a heating element carbon fiber braid are electrically connected with a nickel sheet, a molybdenum bar, a molybdenum sheet and an insulating lead wire end subsequently; the electric heating tube can be in C shape, U shape, omega shape or straight pipe shape. The braided carbon fiber infrared quartz heating tube is widely applied in household heater, electric oven, oven, industrial drying, stoving varnish and other fields in which heating is required, has the advantages of large heating area and high heat efficiency, saves 30 percent to 40 percent of electricity compared with tungsten halogen infrared heating tubes, has low starting current which is 50 percent to 60 percent of working current, realizes automatic soft startup, has safe and reliable circuit, long service life, is convenient to be installed, and is not restricted by the direction.

Description

Braiding charcoal fiber infrared ray quartz heating-pipe

Affiliated technical field

The utility model belongs to a kind of electric calorifie installation, and specifically a kind of is the electric heating tube of heater element with the charcoal fiber woven belt.

Background technology

Existing halogen tungsten filament infrared ray heating tube starting current is big, and the starting current of connecting moment is 8～11 times of operating current, the easy scaling loss of the electric connection point at heating element two ends, and useful life is short, surface area is little, heating efficiency is low.

Summary of the invention

For the deficiency that overcomes that existing halogen tungsten filament heating tube starting current is big, the heat efficiency is low etc., the utility model provides a kind of electric heating tube, makes the starting current of this electric heating tube low, long service life, and heating area is big, heat efficiency height.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of braiding charcoal fiber infrared ray quartz heating-pipe, be in insulation crust, the two ends of heater element are electrically connected with nickel sheet, molybdenum bar, molybdenum sheet, insulated conductor end respectively successively, it is characterized in that heater element is the charcoal fiber woven belt, the type of weave of this charcoal fiber woven belt can be plain weave, twill, satin weave, can certainly be with other suitable manner braiding, its shape of cross section can be pancake, oblateness or circular.This heating tube can be made straight tube shape, U type, C type, Ω type and other various suitable shapes.

The beneficial effects of the utility model are, starting current is low, is 50%～65% of operating current, progressively rises to operating current then, realizes automatic soft start, and the security reliability of circuit is good, long service life; The heating surface (area) (HS of charcoal fiber woven belt is big, the heat efficiency is high, and actual measurement can economize on electricity 30～40%; Easy for installation, the recipient is not to restriction.

Description of drawings

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

Fig. 1 is a kind of Ω type electric heating tube front view of the present utility model.

Fig. 2-Fig. 4 be among Fig. 1 charcoal fiber woven belt node A to enlarged drawing, wherein Fig. 2, Fig. 3, Fig. 4 are respectively plain weave band, twill weave band, satin weave band weavy grain amplification view, charcoal fiber true colors is a grey black, for ease of distinguishing, vertically white band is charcoal fibre bundle warp among the figure, and laterally the black band is a charcoal fibre bundle parallel.

In Fig. 1: 1. transparent quartz tube, 2. charcoal fiber woven belt, 3. nickel sheet, 4. molybdenum bar, 5. molybdenum sheet, 6. porcelain head, 7. fiberglass sleeve, 8. insulated conductor 9. is attached to the getter on the nickel sheet.

Embodiment

In Fig. 1, the two ends of heater element charcoal fiber woven belt (2) are electrically connected with nickel sheet (3), molybdenum bar (4), molybdenum sheet (5) and insulated conductor (8) respectively, the type of weave of charcoal fiber woven belt (2) be plain weave (Fig. 2), twill (Fig. 3) and satin weave (Fig. 4), can certainly select for use other suitable weaving manners that the charcoal fiber is combined into flat band, oblate band or round belt.The shape of heating tube can be C shape, U-shaped, Ω shape, straight tube shape or other suitable shape.

Claims
