Description

Economize on electricity significantly, electric heating installation using oil as medium fast heats up

Technical field

The utility model relates to a kind of electric heating installation using oil as medium, and especially economize on electricity significantly, electric heating installation using oil as medium fast heats up.

Background technology

Electric heating installation using oil as medium is being commonly called as of oil-filled electric heating device, and its advantage is, heating evenly odorlessness, clean environmental protection, feels comfortable.Temperature does not raise when having " Sunny ", electrothermal tube, plane formula warmer over against heat radiation surface, and with regard to cold shortcoming, oily spit of fland makes the heating of whole room when leaving heat radiation surface, and just like the same effect of air-conditioning, but the price in oily spit of fland is merely 5-10/one of air-conditioning.Because the thermal inertia of oil is very big, the oil in oily spit of fland has the heat accumulation function, even outage, the oily temperature in the oily spit of fland still can be kept 10-20 slowly cooling in many minutes, and this is the great advantage that oily spit of fland is different from other warmer.When normal heating work, the oil temperature is in case reduce, and the electric automatic control switch is switched on immediately and heated, and keeps temperature constant constant.The disadvantage in oil spit of fland is, because the thermal inertia of oil is very big, the energising programming rate is very slow, generally reaches 10-20 many minutes, in temperature-rise period power consumption very big, this also is that having of liking of many users that used oily spit of fland adds the reason of hating that also adds.If can accelerate start switches on heat time heating time; Save a large amount of power consumptions in the start heating-up time, then the comfortable effect in oily spit of fland is not inferior to air-conditioning, does not have vexed, the airless problem of air-conditioning yet; More than other warmer " once open heat, cold once closing " common fault.Generally believe in the industry that oily from now on spit of fland is the most promising, the warmer of hommization, development prospect is very big.

Analyze domestic present various forms of oily spits of fland, they exist three big influences to be rapidly heated and the power consumption reason jointly: 1, oil---the thermal conductivity factor of oil is 0.128, be aluminium (thermal conductivity factor: 237) 1/1850; Belong to one of extremely low Heat Conduction Material; So the programming rate of oil is extremely low, and heat insulating coefficient is very high, the temperature storage function is very strong; It is an oily spit of fland disadvantage, is again oily spit of fland biggest advantage simultaneously; 2, the shell fin in most oily spits of fland all is that the sheet metal material is processed, and the thermal conductivity factor of steel is 54, is 1/4 of aluminium, copper (thermal conductivity factor: 401) 1/7; 3, oily spit of fland all adopts electric conversion efficiency to have only the electric heating tube about 35%, becomes the main cause of high power consumption.

Thus, keep the advantage of oil, overcome its shortcoming, improve the shell fin material, superseded electric heating tube adopts new heating material, is the main purpose of this patent.

Summary of the invention

A kind of economize on electricity is remarkable, the electric heating installation using oil as medium fast that heats up, and adopts very high PTC (semistor) element of electric conversion efficiency as heating tube, and power savings very significantly; And oil-electricity separates; Safe, long service life, combination property is far above common electrical heated filament heating tube; Aluminum alloy plate materials fin with high thermal conductivity coefficient replaces sheet metal material fin, accelerates the start programming rate; Still adopt industrial insulating oil to do to heat up, heat; It is high to have kept oily spit of fland comfort level; Temperature stabilization, long, the advantage slowly of lowering the temperature of accumulation of heat time have overcome the shortcoming that oily warm-up time is long, power consumption is big, are the novel energy-conserving products of traditional electrical thermal oil heater upgrading; Novel power saving oil of the present invention spit of fland is expected to replace existing electric heating installation using oil as medium, and it is also advantageous to compare other electric heating device.

The technical scheme of the utility model is:

1, adopt very high PTC (the Positive Tempperature Coefficent-semistor) element of electric conversion efficiency as heating tube, power savings very significantly.The electric conversion efficiency of the heating wire heating tube in traditional oils spit of fland is merely about 35%, and the electric conversion efficiency of PTC heating tube is up to 98%, near 3 times of heating wire heating tube! Heat, in the temperature-rise period, the most of electric energy of electrothermal tube is lost, and only has few part electric energy to become heat energy; PTC heating tube overwhelming majority electric energy directly converts heat energy into.PTC also has exclusive characteristics to be, it is in heating process, and it is big that temperature rising resistance becomes, and its operating current reduces, thereby temperature reduces; Temperature reduces, and resistance reduces, and its operating current increases, and temperature raises, and shows as temperature from steady state, also makes the PTC pipe can not cross cause thermal damage by Yin Jiawen, and increase service life.Oil-electricity separates, and is safe, also is one of advantage of PTC.The PTC element can adopt circle, also can adopt rectangle, perhaps other shape, in a word, to get final product in the pipeline that can feed into heating.

2, the aluminum alloy plate materials fin with high thermal conductivity coefficient directly replaces sheet metal material fin.Present oily spit of fland leans on entirely to oil that heating slowly heats up, and the thermal conductivity factor of oil is very low, is merely 0.128, be aluminium (thermal conductivity factor: 237) 1/1850, belong to one of extremely low Heat Conduction Material, the extremely slow main cause of all oily spit of fland heat temperature raisings now that Here it is.Adopt the aluminum alloy plate materials fin of high thermal conductivity coefficient, during start, the PTC heating tube at first makes aluminium radiator fin heat up rapidly, has overcome the slow problem of conventional oil spit of fland heating; Simultaneously, because fin surrounds thin oil pipe, heating up rapidly, aluminium radiator fin also surrounds heating to the thin oil pipe on the fin; The programming rate of thin oil pipe is accelerated, and so, the temperature rise of whole oily spit of fland oil is also accelerated rapidly; Like this, the raising of dual rate of warming makes oily spit of fland start programming rate faster than sheet metal material fin.Because the temperature in oily spit of fland receives electric automatic control, operating current is on-off-break-make batch (-type) ground constant temperature, temperature control, between the PTC turnoff time; The aluminum alloy heat sink cooling is very fast, but the thermal inertia of oil pipe oil is very big, and it is very slow to dispel the heat; Delayed the aluminium radiator fin temperature-fall period, and Sunny and so on other warmer " once open heat, cold once closing "; Can not shut down during heating, the warmer actual power consumption amount of the continuous mode of heating of this type is very big at all.The oil spit of fland belongs to the batch (-type) heating, and power consumption is littler relatively within the equal heating time.

3,, heat, temperature fall time is all long, adopted such scheme, can overcome the long shortcoming of warm-up time of oil, and kept the advantage of temperature fall time prolongation because the thermal inertia of oil is big.So novel power saving oil of the present invention spit of fland is expected to replace existing oily spit of fland, also can replace other warmer in the larger context.

The useful effect of the utility model is:

1, directly adopt the very high ptc material of electric conversion efficiency as heating tube, 30%-50% can economize on electricity.

2, change the aluminum alloy plate materials fin that sheet metal material fin is a high thermal conductivity coefficient, solved the slow problem of conventional oil spit of fland heating; Electric automatic control makes oily spit of fland be in batch (-type) constant temperature, temperature control duty, and with respect to other warmer, power consumption is littler relatively within the equal heating time.

3, be expected to replace existing oily spit of fland, also can replace other warmer in the larger context.
