Description

A kind of high acting electric heating device

Technical field

This utility model is related to a kind of electric heater, more particularly to a kind of high acting electric heating device.

Background technology

Current electric heater is roughly divided into following type：1st, electric heating installation using oil as medium is typically assembled by multi-disc fin, Gap is formed between each fin, is linked together by the hollow connection sleeve pipe of fin upper and lower ends, dissipated per a piece of Cavity is formed with backing, is filled with conduction oil in which.Electric heating assembly is immersed in conduction oil, is passed by heating conduction oil Pass heat.2nd, PTC warm-air driers it agitate air to flow through PTC heating forced convections using blower fan, as main heat exchange Mode.3rd, it is gas outlet on this electric heater case of convection heater, lower section is air inlet, the sky around energization rear electrothermal tube Gas is heated and rises, and flows out from gas outlet, and the cold air of surrounding is entered from air inlet and supplemented, and such iterative cycles make interior Temperature is improved.4th, radiant type heater is a kind of heating in the form of infrared radiant heat, heating and the heating installation for toasting.

Energy moves to cryogenic object from high temp objects, or high-temperature part of the heat from an object moves to low temperature portion The phenomenon divided is referred to as heat transfer.Heat transfer has conduction of heat, three kinds of forms of heat radiation and thermal convection current.Wherein, electric heating installation using oil as medium heat Main transfer mode is thermal convection current, and is slowly cross-ventilation, and thermal convection current is fluid (including liquids and gases) stream From temperature higher position to the phenomenon of temperature lower heat release during dynamic.Convection current is divided into forced convection and free convection again.The former It is motion of the fluid under exterior power (such as pump, fan, pressure difference etc.) driving；The latter is that fluid is lured because temperature distributing disproportionation is even Send out Density inhomogeneity and produce the motion under buoyancy.Oil Heater belongs to the latter.The convection heat transfer' heat-transfer by convection occurred in pipeline is referred to as internal Problem, it is external issues that fluid flows through the convection heat transfer' heat-transfer by convection occurred during object.

The main transfer mode of PTC warm-air driers and convection heater heat is thermal convection current.Thermal convection current is fluid (including liquid Body and gas) in flow process from temperature higher position to the phenomenon of temperature lower heat release.Convection current be divided into again forced convection and from By convection current.The former is motion of the fluid under exterior power (such as pump, fan, pressure difference etc.) driving；The latter is fluid because of temperature Skewness induces Density inhomogeneity and produces the motion under buoyancy.PTC warm-air driers belong to the former.Occur in pipeline Convection heat transfer' heat-transfer by convection is referred to as internal problem, and convection heater belongs to internal problem, and fluid flows through the convection heat transfer' heat-transfer by convection occurred during object is External issues.

The main transfer mode of radiant type heater heat is heat radiation.Heat radiation transmits the side of energy by electromagnetic wave Formula is referred to as heat radiation.It has continuous radiant-energy spectrum, and wavelength extends to ultra-violet (UV) band from far-infrared band, but longer mainly by wavelength Infrared ray.Property of the energy on radiation source surface launched within the unit interval, in unit area (or absorption) with the surface And temperature is relevant, surface is more dark more coarse, and the ability for launching (absorption) energy is stronger.Any object is all with the shape of electromagnetic wave Formula is to ambient radiation energy.Excitation is constituted the microcosmic of the object when which is propagated and runs into object on road by radiated electromagnetic wave The warm-up movement of particle, makes object heat temperature raising.

Wherein, electric heating installation using oil as medium because when which has heating tasteless, noiselessness, area of heat-supply service it is big, it is applied widely the features such as and It is used widely in the whole world, annual worldwide production 40,000,000.But because electric heating installation using oil as medium is first by conduction oil by heating tube Heating, conduction oil transfer heat to fin surface, and fin surface transmits heat to surrounding air, so as to realize heating, But country's outer surface is 85K for the industry standard of the electric heater of metal at present, as prevents false touch, it is desirable to which outer surface is gold The temperature rise at the position that the electric heater of category is can contact in human body is no more than 85 degree.I.e. to the mistake reacted and take away after human body touching Journey, is unlikely to make one to scald.For ensureing enforcement that above-mentioned industry standard specifies, existing electric heating installation using oil as medium can not be realized with nominal Power is heated for a long time so that the heat generating member in electric heating installation using oil as medium can not all the period of time the maximum heat effect of performance, it is impossible to will The nominal power of heat generating member is played to highest, is caused the waste of resource, and is improve the consumer cost of consumer.

Although PTC warm-air driers can be realized being heated with nominal power for a long time, its air supply areas is limited, and interior The blower fan in portion can produce certain noise, and during use, room air is dried very much, and the scope of application is little.

Although convection heater can be realized being heated with nominal power for a long time, its power is often less, and And cross-ventilated speed is slower, even if the long-time heating of peak power, which radiates mainly by the air outlet of cover top portion, its Area of heat-supply service is still little.

Although radiant type heater can be realized being heated with nominal power for a long time, its area of heat-supply service is little, uses During room air be dried very much, and necessarily with the presence of light when warming oneself, the scope of application is less.

Although the warmer of existing profile structure can be realized being heated with nominal power for a long time, and its heating-surface Product is larger, but its weight is larger, relatively costly.

Electric heating installation using oil as medium possesses above-mentioned every advantage because of which at present, it has also become the main product of warmer industry, is generally disappeared Expense person is received, but electric heating installation using oil as medium is due to the presence of internal conduction oil so as to internal produced by fin in the course of the work Pressure is larger, therefore electric heating installation using oil as medium is very high to the seal request of fin, and its welding procedure is extremely complex；Electric heating installation using oil as medium is full Sufficient outer surface is the design standard of its outer surface temperature rise of electric heater less than 85K of metal, generally can be in the rear end of electric heating installation using oil as medium It is located at bonnet to avoid rear end heatsink temperature too high and scald human body；Also need to arrange tumbler switch on electric heating installation using oil as medium, prevent Its fall after heating dry combustion method and cause danger；The above-mentioned ad hoc structure of electric heating installation using oil as medium all considerably increases its production cost.
