Abstract
The utility model discloses a tubular heater comprising a metal inner tube, wherein the upper external surface of the metal inner tube is coated with an internal insulating layer that is externally provided with a heating layer, and the heating layer is further externally coated with an external insulating layer; and the heating layer is formed by spiral winding of a flat heating belt, and electrical connectors are reserved at two ends. The tubular heater has simple structure and high heating efficiency, and is especially suitable for an electric heating faucet and an instantaneous heater; the structure of the like product can be simplified, the price is lowered, and the service life is prolonged.
Description
Technical field
The utility model relates to electric heater unit, particularly a kind of tubular heater.
Background technology
Present various electric heater unit emerges in an endless stream, and evolves to board-like heating gradually by original heating wire heating, but still can not satisfy people's demand along with the development of demand.
The utility model content
For satisfying the growing demand of people, the utility model provides a kind of tubular heater.
The utility model tubular heater comprises metal inner pipe, and outer surface on metal inner pipe is covered with one deck inner insulating layer, is provided with zone of heating outside inner insulating layer, and zone of heating covers an external insulation layer outward again.
Described zone of heating adopts flat heating tape, is entwined by helical form, reserves electrical connector at two ends.
The utility model tubular heater, simple in structure, the efficiency of heating surface is high, be particularly suitable for electric hot water tap, instantaneously heated type heater uses, can simplify this series products structure, reduce price, and improve useful life.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model tubular heater;
Fig. 2 is the utility model tubular heater end view.
Embodiment
Below in conjunction with embodiment the utility model tubular heater is done detailed explanation.
Fig. 1 is the cutaway view of the utility model tubular heater, and Fig. 2 is an end view.
The utility model tubular heater comprises metal inner pipe 1, and outer surface on metal inner pipe 1 is covered with one deck inner insulating layer 2, is provided with zone of heating 3 outside inner insulating layer 2, the zone of heating 3 outer external insulation layers 4 that cover again.
Zone of heating 3 adopts flat heating tape, is entwined (see figure 2) by helical form, reserves electrical connector at two ends.Because zone of heating 3 almost is to manage in directly being wound on 1, efficiency of heating surface height, thermal loss is few.
Claims (2)
