CN205987427U - Novel ribbon heater - Google Patents

Abstract

The utility model discloses a novel ribbon heater, including corrugated metal pipe, heat -conduction insulation layer, metal ground plane and heat -conduction insulation layer, the outside of corrugated metal pipe outwards sets gradually heat -conduction insulation layer, metal ground plane and heat -conduction insulation layer to constitute the ribbon heater body. The utility model discloses under the condition of the same metal sectional area, existing to the current heart yearn that generates heat, sectional area that the corrugated metal pipe possess wants big many, and the unit area load of controlling into the source that generates heat behind the ribbon heater with corrugated metal is little, and it is low to issue pyrogen piece surface temperature in the condition of the same power, owing to the general temperature resistant of heat -conduction insulation layer of corrugated metal outside of tubes is the highest 260 degrees centigrade of left and right sides, so the lower source surface temperature that generates heat can improve the quality of product. This practicality sets up the metal wire on the inner wall of corrugated metal pipe or outer wall for adjust the unit length power of ribbon heater body.

Description

A kind of Novel electric torrid zone

Technical field

This utility model is related to a kind of ribbon heater, specifically a kind of Novel electric torrid zone.

Background technology

Ribbon heater is the heating of self limiting temperature heating tape, is equably to extrude one layer between two parallel metal buses There is the core ribbon that positive temperature coefficient quasiconductor ptc material is made, the operation principle of self limiting temperature heating tape and feature：Self limiting temperature heating tape Heating, be equably to extrude one layer between two parallel metal buses there is positive temperature coefficient quasiconductor ptc material system The core ribbon becoming.When two buses of cable one end and power on, electric current flows transversely through ptc layer from a bus and reaches separately A piece bus, PTC layer is exactly the resistance heater being continuously connected in parallel between bus, converts electrical energy into heat energy, to operating system Carry out tracing thermal-insulating.Core ribbon resistance raises with temperature and increases, and has arrived high resistance area, and big the arriving of resistance almost blocks electric current, core ribbon temperature Just reach high limit and no longer raise but automatic temp limit.

Pyrotoxin is wanted based on the heart yearn that generates heat in traditional ribbon heater.

Utility model content

The purpose of this utility model is to provide the Novel electric torrid zone that a kind of sectional area is big, unit area loading is little.

For achieving the above object, this utility model provides following technical scheme：

A kind of Novel electric torrid zone, including metal bellowss, thermally conductive insulating layer, metal ground plane and thermally conductive insulating layer, described The outside of metal bellowss outwards sets gradually thermally conductive insulating layer, metal ground plane and thermally conductive insulating layer, thus constituting ribbon heater Body.

As further program of the utility model：Metal wire is arranged on the inwall of described metal bellowss or outer wall.

As this utility model further scheme：Described metal wire is cylindric or flat.

Compared with prior art, the beneficial effects of the utility model are：

In the case of same metal sectional area, referring now to existing heating heart yearn, the section that metal bellowss are had Long-pending will be big many, the unit area loading making pyrotoxin behind ribbon heater with metal bellowss is little, in the case of equal-wattage Heating original paper surface temperature low, due to metal bellowss outside the general heatproof of thermally conductive insulating layer up to 260 degrees centigrade, institute The quality of product can be improved with relatively low pyrotoxin surface temperature.This practicality sets on the inwall or outer wall of metal bellowss Put metal wire, for adjusting the unit length power of electric heating band body.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Refer to Fig. 1～4, in this utility model embodiment, a kind of Novel electric torrid zone, exhausted including metal bellowss 1, heat conduction Edge layer 2, metal ground plane 3 and thermally conductive insulating layer 4, the outside of described metal bellowss 1 outwards set gradually thermally conductive insulating layer 2, Metal ground plane 3 and thermally conductive insulating layer 4, thus constituting electric heating band body, metal bellowss 1 can free bend it is ensured that it makes With conveniently.

Metal wire 5 is arranged on the inwall of described metal bellowss 1 or outer wall, metal wire 5 is cylindric or flat, For adjusting the unit length power of electric heating band body.

Operation principle of the present utility model is：

Pyrotoxin is wanted based on the heart yearn that generates heat in traditional ribbon heater, in identical gold compared with metal bellowss 1 (metal hose) In the case of belonging to sectional area, sectional area that metal bellowss 1 (internal is hollow-core construction) are had wants big many, uses wavy metal The unit area loading little (unit power/unit area) of pyrotoxin behind ribbon heater made by pipe 1, sends out in the case of equal-wattage Pyrogen part surface temperature low (unit heating surface amasss the * heat transfer coefficient * temperature difference=unit power), due to metal bellowss 1 outside The general heatproof of thermally conductive insulating layer up to 260 degrees centigrade, so relatively low pyrotoxin surface temperature can improve product Quality.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as limiting Involved claim.

Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment only wraps Containing an independent technical scheme, only for clarity, those skilled in the art should for this narrating mode of description Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined Understandable other embodiment.
