Abstract
The utility model discloses an electric heater, which comprises a heating element and a heating body. The heating body is made of X-type aluminum alloy; the heating element internally comprises an insulating material and a plurality of heating units for independent power supply; the heating units are vertically arrayed in the heating element; one ends of the heating units are riveted with each other, and the other end is connected with a high temperature leading wire; the insulating material is filled in a cavity surrounded by the heating units and the heating body; the heating units are preferably three in number. The electric heater of the utility model is processed integrally with aluminum alloy and takes the shape of an X, and has high heat transmission efficiency, low surface temperature and three different heating powers.
Description
Technical field
The utility model relates to a kind of firing equipment, particularly a kind of X type electric heater.
Background technology
The principle of electric heater is that gas medium to be heated shell side inlet from electric heater is entered, and along the inner heat exchange process of electric heater, absorbs the heat that the electrical heating elements surface gives out, and satisfies the process of the medium of technological requirement in electric heater outlet acquisition.The conventional electric heating device be stainless steel tube or outside stainless steel tube around steel disc, but between sheet and steel pipe, thermal resistance is arranged, influenced the radiating effect of electric heater, reduced the operating efficiency of electric heater.In addition, the conventional electric heating device has only a heater, so have only one grade of electrical heating power, uses inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of electric heater, processes by X type aluminium alloy extrusions integral body, and the heat transfer efficiency height, surface temperature is low.
A kind of electric heater described in the utility model comprises heat generating component and radiator, and described radiator is an X type aluminium alloy radiator; Described heat generating component inside comprises insulating material and a plurality of independently-powered heater, described heater is vertically arranged in heat generating component, one end of heater is riveted mutually, and the other end connects high temperature wire, and described filling insulating material is in the cavity that described heater and radiator surround; Described heater number is three.
Electric heater of the present utility model is processed by aluminium alloy extrusions integral body, is shaped as the X type, the heat transfer efficiency height, and surface temperature is low, and three kinds of different heating powers are arranged.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model is not subjected to the restriction of embodiment.
As shown in Figure 1-Figure 3, a kind of electric heater of the utility model comprises radiator 1 and contains the heat generating component of heater 3 that described radiator 1 is an X type aluminium alloy radiator, the heat transfer efficiency height is arranged, the characteristics that the radiator surface temperature is low; There are three heaters of vertically arranging 3 described heat generating component inside, one end of heater 3 is riveted mutually, and the other end connects high temperature wire, the resistance difference of three heaters of vertically arranging 3, by making up the variable three kinds of heating powers that swap out in twos, the user can select as required.
The utility model heat generating component also comprises insulating material 2, and insulating material 2 is filled in the cavity that described heater 3 and radiator 1 surround, and is used for realizing electrical isolation each other at three heaters 3, avoids interacting; Also comprise refractory seals rubber ring 4, be used for,, fix the relative position of three high temperature resistant wires simultaneously at the heater outlet with radiator 1 and extraneous the isolation with the sealing of the insulating material around the heater; Also comprise Wire sheath 5 and high temperature resistant wire 6, be used to prevent that the too high insulation of dissolving lead of radiator temperature from making the charged and short circuit of radiator, prevent that simultaneously heater 3 power are too high, the electric current of lead is excessive, produces high temperature, burns lead and causes the accident.
After the energising of this X type electric heater,,, can realize the heating of three kinds of different capacities by three heaters are controlled in twos according to user's needs.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
Claims (3)
1. an electric heater comprises heat generating component and radiator, it is characterized in that described radiator is an X type aluminium alloy radiator, and described heat generating component is positioned at the center of described X type radiator.
2. electric heater as claimed in claim 1, it is characterized in that described heat generating component inside comprises insulating material and a plurality of independently-powered heater, described heater is vertically arranged in heat generating component, one end of heater is riveted mutually, the other end connects high temperature wire, and described filling insulating material is in the cavity that described heater and radiator surround.
