Abstract
The utility model relates to an electric appliance element, particularly an electric heating element for heating water, which can be used for an electric water heater. The utility model comprises an outer shell, a heating element and dielectric filling, wherein the outer surface of the outer shell is also provided with at least one heat conduction fin. The utility model has the advantages of simple and reasonable structure, easy fabrication, high heat efficiency, low cost and long service life.
Description
(1) technical field
The utility model relates to a kind of electric elements, and especially a kind of electrical heating element to the water heating can be used for electric heater.
(2) background technology
Existing electric heater often adopts the metal shell tubular electrical heating element, its structure is such: be shell with the metal tube, heating alloy is a heater, fills fixedly heater of closely knit magnesium oxide powder dielectric in metal tube, and its concrete structure is seen Fig. 1.When electric heater uses for a long time, owing to contain a certain amount of solid matter that is insoluble in the water, when heating, fixed substance is cemented in the metal tube surface and forms incrustation scale, and constantly thickening, hinders heat exchange, the metal tube temperature is raise, easily cause metal tube distortion, drawing crack, damage.
(3) summary of the invention
The purpose of this utility model is to provide a kind of non-damageable electrical heating element.
For achieving the above object, the utility model is by the following technical solutions:
A kind of electrical heating element comprises shell, heater and insulating packing, and the outer surface of shell also is provided with a slice heat conduction fin at least.
The heat conduction fin can make heat exchange away from shell, and incrustation scale is less to the shell influence, and shell will remain on low-temperature condition, and damage is difficult for breaking.And the heat conduction fin also strengthened heat transfer area, improved the heat efficiency.
Technique scheme can also be further improved by following technical measures.
Described shell is a metal tube, and described heat conduction fin is a sheet metal.
Described heat conduction fin is plane and is positioned at the radial section of shell.
Described heat conduction fin in the form of a ring and vertical sleeve be located on the shell.
Described heat conduction fin in the shape of a spiral the shape dish on shell.
The utlity model has following advantage: simple and reasonable for structure, easy to manufacture, heat efficiency height, cost is low, and the life-span is long.
