Abstract

The utility model provides an improved flexible heating element, and a heating band of which is formed by vertically and horizontally waving resistance wires and isolating fiber across. The utility model is suitable for winding and heating the surfaces of objects with complex shapes.

Description

Flexible heating component

The utility model relates to a kind of improved flexible heating element.

The heating tape of flexible heating element was normally having the resistive layer that forms with the carbon powder embedding on the flexible non-conductive material, as just having proposed this scheme among the U.S. Patent application No4058704 in the past.Because this resistive layer is to form with the carbon powder embedding on non-conductive material, thereby this heating tape twines repeatedly, and the carbon film layer is easy to generate be full of cracks, has shortened useful life.

The purpose of this utility model is will overcome above-mentioned shortcoming a kind of flexible heating element that can never occur chapping that twines repeatedly is provided.

The utility model is achieved like this: become flexible heating tape with resistance wire, non-conductive fibre longitude and latitude interlacing, and coat silicone rubber jacket on this surface, heating tape.

Because the resistive layer that heating tape of the present utility model adopts resistance wire, non-conductive fibre longitude and latitude interlacing to become rather than the carbon powder of the easy be full of cracks of employing is formed is so be full of cracks can never appear in the heating tape; Simultaneously, because the heating tape can use alloy resistance wire and surface, heating tape to coat silicone rubber jacket, the heating element surface loading can be done very highly.

Further describe the utility model below in conjunction with accompanying drawing for embodiment.

Fig. 1 is the structural representation of the utility model one embodiment.

Fig. 2 is a kind of electrical connection diagram of the utility model one embodiment.

Fig. 3 is the another kind of electrical connection diagram of the utility model one embodiment.

Fig. 4 is another three-phase electrical connection diagram of the utility model one embodiment.

Referring to Fig. 1, (1) is flexible heating tape, it is to become the heating tape with some alloy resistance wires (2) with alkali-free glass fibre (3) longitude and latitude interlacing, and heating tape length requires according to heating power and decides, and coats silicone rubber jacket (4) on the surface, heating tape then and constitutes heating element.This heating element electric connecting mode can be as required as Fig. 2, Fig. 3 and Fig. 4 mode, alloy resistance wire is twisted into lead terminal (5), (6), (7) get final product.Electric current is powered to the alloy resistance wire in the heating element by lead terminal during work, and alloy resistance wire produces heat and carries out heat conduction by silicone rubber jacket.

When this flexible electric heating element is wrapped in any complicated shape object surfaces, for example on the wall of pipe or jar shape object, just can easily heating object be heated and be incubated.

Claims

A kind of flexible heating element is made up of flexible heating tape [1] and sheath [4], it is characterized in that flexible heating tape [1] is formed by resistance wire [2], non-conductive fibre [3] longitude and latitude interlacing.
