Description

A kind of efficient energy-saving electric heater

Technical field

The utility model relates to a kind of electric heater, especially a kind of efficient energy-saving electric heater.

Background technology

At present, electric heater kind of the prior art is a lot, but its common problem is arranged is exactly that power consumption is bigger, generally all will be more than 750 watts, many will reach 1800 watts.Be exactly that area of dissipation is little more in addition.Electric heater with the heater element of existing electric heater is made will increase area of dissipation, then also will increase power consumption.A kind of heating cable is arranged in the prior art, and name is called the self-limited type heat tape, and there is Xie Chang wire ﹠ cable factory, Beijing etc. in its manufacturer.This heating cable heats up in the energising rear surface and reaches 65 ℃-85 ℃, after it reaches the highest steady temperature and makes the indoor temperature of certain space reach its startup constant temperature value that sets up on their own, its power consumption just reduces greatly, and can under the very little situation of power consumption, keep 58-78 ℃, if the room temperature in this space does not reduce, it is big that power consumption can not become.If make electric heater, just can reduce the power consumption of electric heater greatly with such cable.

Summary of the invention

The purpose of this utility model is to solve the bigger problem of electric heater power consumption in the prior art, and a kind of efficient energy-saving electric heater that can reduce power consumption under the prerequisite of the heating-up temperature that meets or exceeds existing electric heater greatly is provided.

The purpose of this utility model is achieved in that

This electric heater has the heat conduction shell that its inside is provided with several chambers that are interconnected, in described chamber, be sealed with heat-conducting medium or form vacuum, to improve the thermal conductivity of cavity space, in each chamber of this heat conduction shell, be equipped with the self-limited type heat tape in mutual electrical connection formation loop, the outer surface of described heat tape is an insulation sheath, portion is lead and core material within it, the termination of described heat tape wherein is provided with the pin member that is connected with power supply by drawing in the described heat conduction shell.

Described heat conduction shell can be that various materials with heat conductivility are made preferred metal materials.

Described heat-conducting medium can liquid thermal conductivity media, as water, insulation wet goods, also can be the solid conductive heat medium, as charcoal powder or charcoal particle.

Heat tape outlet place at heat conduction shell is provided with sealing device, to seal heat-conducting medium wherein and to make described heat tape draw described chamber.

For described heat tape can firmly be provided with in being filled with the chamber of heat-conducting medium, be preferably in and be provided with the heat tape support in the described chamber, its card establish with chamber in, which is provided with heat tape perforation with heat tape cross section coupling, described heat tape is by passing in this perforation, floats with heat-conducting medium when the variations in temperature with the heat tape that wears in liquid thermal conductivity media in avoiding especially.Corner at described heat conduction shell chamber especially will be provided with described support, when avoiding floating and the insulation sheath of chamber wall friction damage on it.

In the chamber of described connection, described heat tape can come and go and repeat to pass same passage more than twice.

Described heat conduction shell can be a staggered or pipe of the various moulding of interleaved discs coiled not, and the termination of the described heat tape that wherein wears passes on the termination by pipe, pipe sealed at both ends.Thus, can form this electric heater of various moulding.

The efficient energy-saving electric heater that the utility model provides is by wearing the self-limited type heat tape in the conducting medium in heat conduction shell, compare with electric heater of the prior art and to have the little characteristics of power consumption, simultaneously, design structurally makes heat tape can be in heat conduction shell efficient more, safety firmly be set in the chamber of falling heat-transfer medium.In addition, the heater element in this electric heater is the ribbon cable with certain flexibility, in conjunction with tubular shell, can constitute the electric heater of different modeling and increases the volume that heat exchange area increases electric heater with exceeding.
