Description

A kind of electric heater

Technical field

The utility model relates to a kind of heater, is meant a kind of some fin and heat-generating pipe of comprising especially, and this heat-generating pipe is plugged in the heater in some these fin successively.

Background technology

As everyone knows, along with the progress of society more and more can be convenient for people in the now very general life that has been applied in people of the apparatus of daily life, and in this class apparatus, especially be subjected to liking of people with the electric energy apparatus, it has transmission conveniently to electric energy when in use as a kind of clean energy resource, produce easy-to-use characteristics, so a large amount of apparatus adopts power-actuated mode to work now.

People often need carry out liquid the work of temperature raising in the process of concrete productive life, traditional fado of doing is to adopt by combustion fuel to obtain thermal source and further utilize thermal source that liquid is heated, the mode that mostly is employing burning coal or fuel oil, combustion gas in concrete enforcement is carried out, and its operating procedure is also more loaded down with trivial details simultaneously and this mode of heating not only can produce a large amount of waste gas.

Some electric heaters have appeared in people's the life under above-mentioned social background, with regard to the electric heater of present appearance, its structure generally all comprises Power tabs and electrothermal tube, by Power tabs electric power is introduced in the electrothermal tube when in use, electrothermal tube is inserted in the liquid and this moment and converts electrical energy into heat energy to reach the purpose of heating by electrothermal tube, but traditional not high while of its whole heating efficiency of this class electric heater is because its structure too simply often exists some potential safety hazards, and this is the major defect for conventional art.

Summary of the invention

The utility model provides a kind of electric heater, its heating efficiency height, and the integral heat sink excellent in efficiency can greatly facilitate people and use, and this is a main purpose of the present utility model.

Technical solution adopted in the utility model is: a kind of electric heater, it comprises some fin and heat-generating pipe, this heat-generating pipe is plugged in some these fin successively, the utility model is in work, this heat-generating pipe connects external circuit, electric energy is transferred in this heat-generating pipe, and converts electrical energy into heat energy by this heat-generating pipe, and finally by some these fin thermal energy transfer is gone out.

Each this fin all comprises plate body, perforation and connecting ring, and wherein, this perforation is opened on this plate body, and this connecting ring is fixedly connected in this perforation, and this fin is made by metallic aluminium.

This heat-generating pipe comprises and draws rod, sleeve pipe and terminal plate, wherein, this draws rod and is plugged in this sleeve pipe, and this terminal plate is fixedly connected on this two ends of drawing rod, is filled with heating layer in this sleeve pipe, draw in this sleeve pipe and this at these sleeve pipe two ends and to be arranged with plug between the rod, offer connecting hole in this plug, this draw the rod in this connecting hole, pass, this plug is made by ceramic material, this casing pipe sleeve is located at and connects in the aluminum pipe, and this connection aluminum pipe is connected between this connecting ring and this sleeve pipe of this fin.

The beneficial effects of the utility model are: draw rod because this heat-generating pipe of the present utility model comprises as mentioned above, sleeve pipe and terminal plate, wherein, this draws rod and is plugged in this sleeve pipe, this terminal plate is fixedly connected on this two ends of drawing rod, be filled with heating layer in this sleeve pipe, draw in this sleeve pipe and this at these sleeve pipe two ends and to be arranged with plug between the rod, offer connecting hole in this plug, this draws rod and passes in this connecting hole, this casing pipe sleeve is located at and connects in the aluminum pipe, this connection aluminum pipe is connected between this connecting ring and this sleeve pipe of this fin, and the efficiency of heating surface that can promote integral heater by above-mentioned structure improves the security protection coefficient of heater simultaneously.
